Connection to the mains
Read the "Safety Instructions" before using instrument!
Make sure that the mains switch is at "0". Connect mains cable to the connector on the rear panel with mains 230 V/50 Hz. Switch the main switch to "1". The program number, the preset treatment time, and the ultrasound frequency are lit up on the display. Choose the irradiation surface area and the emitter head (1 cm
2
or 4 cm
2
). Connect the emitter head with emitter head connector on the front panel. Never change emitter heads during ultrasound generation. Change emitter heads only if the instrument is switched off with the START/PAUSE button (17). Use RESET button if you begin therapy with another patient.
Choosing the ultrasound frequency
Use the FREQUENCY push-button (15) to choose the 1 MHz or 3 MHz frequency. The green diodes (13), situated to the left of the FREQUENCY button, indicate which of the two frequencies is activated. Both frequencies can be applied with either emitter head sizes. Choose a 1 MHz frequency if you wish to therapeutically affect deep tissues and a 3 MHz frequency for superficial tissues.

emitter head to Connector (11) and the
be used for either continuous or pulse modes and for both frequencies. The emitter head must be connected before intensity of acoustic output is set. The therapy cannot start without connecting and identifying the emitter head. The red diode on the emitter head indicates insufficient contact between the emitter head and the tissue. If contact is insufficient, the control light lights up red. The countdown on the TIME display (3) stops. Power absorption (indicated by the light blinking) stops. Therapy is interrupted until contact is restored. If there is proper contact, the control signal on the emitter head will light up green.
Choosing PPR (pulse-to-period ratio)
Different pulse-to-period ratios are related to different ultrasound thermic effects. Continuous ultrasound deeply heats tissues. A 1:2 or 1:4 PPR ultrasound only has a moderate thermic effect and 1:8 or 1:16 PPR ultrasound has an athermic. Use the DUTY CYCLE push-button (9) to set the PPR. The activated PPR is indicated by the green diode (17).
Choosing pulse frequency
The pulse ultrasound (1:2 - 1:16 PPR) allows the user to choose one of the pulse frequencies and the time duration. The BTL-07p uses 50 Hz and 100 Hz pulse frequencies. Press the PULSE FREQUENCY button (16) to switch between the two frequencies. The activated pulse frequency is indicated by the diode next to the PULSE FREQUENCY button (14). Impulse and pause duration of both frequencies are specified in the following tables.

BTL – 07p operating manual & user's guide
Time setting
The therapy time is shown on the TIME display (3). Press the up/down arrow push-buttons to increase or decrease time (4). The time is adjustable in steps of 0.5 minute up to 5 minutes and in steps of 1 minute up to 25 minutes. The maximum application time is 25 minutes. Hold the up/down push-button pressed to increase or decrease time.
Ultrasound generation
Generation of ultrasound begins after the following operations have taken place: Connect an emitter head to the instrument. Set intensity and time. READY control light should light up. If it does not, check the emitter head (19) connection and the head type (5). Try the other emitter head (8). Press START/PAUSE push-button (18). The set time must not be 0. The time display starts to count/down the pre-set time. If there is sufficient contact between the emitter head and the skin, the “Program” display will stop showing the program number and will start to count the amount of absorbed energy. The lowest green light in the CONTACT row will light up (10) and the light in the TIME and INTENSITY decimal boxes will start to blink. The columnar graph (10) and the emitter head control light both monitor the quality of contact during application. If contact is insufficient, diodes light up red. If this happens, moisten the skin with more ultrasound gel. A cold emitter head can also cause insufficient contact. In this case set the intensity to 0.1 W/cm
2
and generate ultrasound for approximately 1 minute to warm up the head. Then set the intensity. If there is insufficient contact between the head and the patient, the unit stops. If there is proper contact, the therapy continued. All parameters can be changed at any time.
Indication of stationary waves
Any ultrasound application to a bone or bony area situated just under the skin (condyles, epicondyles, ankles) may, if the emitter head is not moved sufficiently, result in interference between a reflected wave and an arising wave arising (stationary wave). Consequently, there are "peaks of intensity". A peak of intensity is an area, which is exposed to intensity higher than the preset intensity level. There is an increased local temperature in these areas. BTL-07p emitter heads have a very low BNR. Further more, the BTL-07p features an optic indicator to signal stationary waves, placed on the Bar-graph (10) (the orange LED diode). Respond to this signal by immediately removing the emitter head from the application site in order to eliminate any risk of soft tissue damage.
Interrupting the therapy
Pressing the START/PAUSE push-button (18) immediately interrupts the therapy. The time countdown stops and the pre-set intensity level, as well as the amount of absorbed energy, do not change. To continue therapy, press the START/PAUSE push-button again. To start a new treatment, set the time and start the ultrasound generation.
Selecting the program
The unit has pre-set programs for ultrasound and combined ultrasound/electrotherapy. The list of programs and procedures can be found in the user’s guide. Press button (2) to select the program or diagnosis. Any parameters can be changed before starting the application. Press the START/PAUSE button (18) to start the therapy.
Saving personalised programs
The BTL-07p enables you to save your own programs, which can be stored under codes 80-99. Set all the parameters. Press and hold the START/PAUSE button. After 2 seconds the bar-graph (10) blinks and there is an acoustic signal. Programs are stored when the unit is turned off.
Combined ultrasound/electrotherapy
The BTL-07p allows the user to apply ultrasound and electrotherapy at the same time. The ultrasound instrument can be connected to the BTL-06 electrotherapy unit. Do not connect the BTL-07p to electrotherapy units manufactured by other companies.
Connecting the units
Place the BTL-06 on the ultrasound BTL-07p. For combined therapy, the units are connected with a special cable. Plug the cable connector of an ultrasound emitter head into the outlet on the front panel (21). Insert the cable for combined therapy into the electrotherapy unit outlet (channel B for voltage mode). Insert the red banana plug into the BTL-07p outlet (20). Connect the electrode to the green banana plug. The ultrasound emitter head then serves as the anode (+) and the electrode as the cathode (-).

BTL – 07p operating manual & user's guide
Starting the combined therapy
Set the instruments after they are connected. Set all needed parameters on the BTL 07p and press the START/PAUSE button (17). Press the STOP button (V/mA) (18) to set the voltage (the V control light is on). Choose the program and set the therapy time. Apply the electrode and the emitter head to the treatment area. The moment the emitter head touches the skin, the ultrasound will start and the time will begin to count down. Press the button (19) on the electrotherapy unit to set the voltage and start the combined therapy. Caution: Keep the ultrasound emitter head on the treated area during the therapy!
Ending the combined therapy
After the pre-set time has elapsed and the START/PAUSE button (17) on the BTL-07p has been pressed, the combined therapy stops. If there is a need to stop or interrupt the application before the pre-set time elapses, press the button (18) on the BTL-06 before removing the emitter head or the electrode from the skin.

Important!
Each BTL-07p instrument has its own specific ultrasonic emitter heads that are produced and set only for that particular unit. Do not use emitter heads from a different BTL-07p unit or an ultrasound unit made by another producer. Protect the emitter heads from shock or intense cold. Do not bend the cable. Be especially careful with the emitter head connection area. Regularly disinfect emitter heads with a commonly used disinfectant.

BTL – 07p operating manual & user's guide
II. USER'S GUIDE
Mechanical waves with a frequency higher than 20,000 Hz are called ultrasound. Ultrasound is not generated electronically for the application of therapy and is classified as mechano-therapy.
Mechanism of action
If a minimal air gap between emitter head and body surface is eliminated, the emitter head vibration will be more easily transferred deeply into the tissues in the form of longitudinal waves. Every cell in the path of the ultrasonic "beam" will begin to oscillate: a micro-massage is followed by a transformation from gel to sol (jelly structures becoming liquefied) and transformation from mechanical to thermal power, with deep warming of tissues. The amount of heat generated is dependent on the amount of energy that is absorbed. Other effects of ultrasound (solution degassing, cavitation arising of cavities in humour, and local alkalization) are negligible with the small intensities and ultrasound doses that are used for physical therapy. The prophylaxis of ultrasound side-effects must include the knowledge that molecular oscillation occurs not only in the course of the ultrasonic beam but, as a result of humour transportation to areas that are distant from the application site, may possibly result in the restoration of former epistaxis or the acceleration of menstruation. The quality of an ultrasonic beam and its distance from the emitter head determine its characterization as a close or distant ultrasonic field. Great variation in ultrasound intensity caused by interferential effects and low beam divergence is typical characteristics of a close ultrasonic field. The length of the close field is directly proportional to the effective emitting surface of the emitter heads (ERA) and indirectly proportional to the frequency. For example, the length of a close field with a 4 cm cm; the length of a close field with a 1 cm
2
2
ERA emitter head and a 1 MHz frequency is 2 cm.
ERA emitter head and a 1 MHz frequency is approximately 10
The characteristics of a distant ultrasonic field are increasing beam divergence, gradual decrease in intensity and almost no interferential processes. Therapeutic effects take place mostly in a close field. Since the ultrasonic beam in a close field shows marked interferential effects (interference of applied and reflected waves, both constructive and destructive), the result is an uniform ultrasonic beam. The beam’s peaks of intensity (local increase in intensity caused by constructive interference) may reach values many times higher than the preset value (the rise of stationary waves). The Beam Non-uniformity Ratio (BNR) illustrates how often peaks of intensity exceed preset values. This value is characteristic for an ultrasonic head when the frequency is fixed. A good quality head should not exceed 6. With a preset intensity of 1 W/cm
2
, the intensity should not exceed 6 W/cm2 in any part of the ultrasonic beam.
The BNR of older ultrasonic heads, as well as many of the newer ones (where the producer does not mention the BNR), is often 20 or more!
The Effective Radiating Area (ERA) is always smaller than the actual surface area of the emitter head (the ERA is determined by the size of the piezoelectric crystal or ceramic table that generates ultrasound by oscillating). The dose of ultrasound (amount of power emitted to surface area) is therefore related to the ERA, not to the actual surface area of the emitter head.
Refraction and reflection of ultrasound follow the laws of wave physics. They originate from ultrasonic wave transmission between tissues and the differences in vibration flow speed in these tissues. Therapeutic application must include elimination of the air gap between the emitter head and skin (a 10 ultrasonic wave reflection because of the marked difference in the air and skin flow speed. With a pre-set intensity of 1.0 W/cm
2
, the tissue receives only 10 mW/cm
2
- energy without any biological effect). Therefore, modern
-9
m thick air gap causes 99 %
ultrasonic heads have a built-in optic and/or acoustic unit that gives a signal and stops the time counter when contact is insufficient. Ultrasonic beam power increases (constructive interference) and decreases (destructive interference) occur as a result of interference in the close field, which reaches its peak (up to 35 %) at the soft tissue-bone boundary. It is necessary to move the emitter head continuously (see below) to prevent tissue lesions at peaks of intensity. The BTL-07p signals when there are stationary waves and stops ultrasonic power generation until stationary waves are eliminated through more rapid movement of the emitter head. As a result of reflection and constructive interference increases in local intensity and temperature may occur, particularly in the periosteum-bone boundary. This increase can cause periosteum pain during treatment. When this occurs, the intensity must be lowered immediately. Ultrasound is primarily absorbed in deep tissues. Since these tissues contain virtually no thermoreceptors, it is impossible to perceive a rise in local temperature. Nociceptive receptors are irritated and the patient feels pain only if the local temperature exceeds 45
ο
C. Most experts agree that a short-lasting local temperature of 45οC is not dangerous. As far as classic inflammation (edema, erythema, local temperature increase, pain, and non-function) is concerned, additional heat production is contraindicated. In certain cases, only a pulse ultrasound (athermic) can be applied. In the peracute period of post-traumatic states (up to 24 - 36 hours), even pulse ultrasound application is contraindicated (resulting vibrations obstruct capillary proliferation and may cause laggard bleeding).
page 11
BTL – 07p operating manual & user's guide
Increases in local temperature and micromassage have several physiological effects:
1. Improvement in local circulation resulting in metabolic improvement. Vasodilatation increase follows the
increasing temperature (more evident in continuous ultrasound).
2. Increased permeability of capillaries resulting in quick extravasation humour absorption.
3. Improvement in local circulation and decreased orthosympathic activity, leading to marked muscle relaxation.
4. Local ischemia pain improvement.
5. Transformation from gel to sol occurs as a result of fibrinogen to fibrin transformation, and haematoma and
edema transform to gel. Ultrasound dissolves this gel and hastens reabsorption. Since fibrinogen to fibrin transformation is a fundamental feature of the healing process (scar formation), we do not recommend the application of ultrasound during the peracute post-traumatic period.
6. Tissue regeneration improves as a result of the above-mentioned effects.
Ultrasound can also have several negative effects:
1. Tissue lesion - a mechanic and/or thermic tissue lesion can occur when intensity is too strong. Particularly
sensitive is the nervous system (peripheral nerve), which is situated just on the bone (interference) and just below the surface (close field). If intensity is too strong, flow speed can decelerate in the corresponding nerve, followed by a total (reversible) impulse flow block and irreversible disintegration of the neuron (myelin coats are preserved). Bone projections just under the skin (ankles, epicondyles, spondyle spines, etc.) are also sensitive.
2. Leukocyte mobility impairment is minimized by sufficiently moving of the emitter head.
3. Other negative effects, largely caused by overdoses, are possible: glycemia decline, increased fatigue,
nervousness, changes in appetite, constipation, increased tendency to catch colds (common and severe).
Methods of application
A) Application site and movement of the emitter head
1. Static application: A special holder fixes the emitter head at the application site and emitter head is not
moved. This is the least suitable method because of the possibility of the above-mentioned adverse effects.
2. Semistatic application: Employed when the application site corresponds with the ERA of the emitter head.
The therapist moves the emitter head continuously in a circular pattern.
3. Dynamic application: Employed when the application site is larger than the ERA of the emitter head. The
therapist moves the emitter head in a circular pattern. The application time is prolonged proportionally to the ERA and the size of the application site.
B) Application site
1. Local application: The ultrasound is applied to the affected site. This is the most common type of application,
and is particularly suitable for the management of muscle spasm, chronic post-traumatic edemas, etc.
2. Segmental application: The ultrasound is applied to the nerve radix outflow of the affected site (e.g., Sudeck
syndrome, morbus Raynaud). This method of application is paravertebral and homolateral, making it suitable for the management of limb diseases (arms C5 - Th1, legs L3 - S1).
3. Neural application: Based on the effect of flow speed decrease in the peripheral nerve to which ultrasound
has been applied. The boundary between the lowering of conductivity and irreversible nerve damage (asymptomatic) is very narrow. Neural application is considered risky and indicated infrequently as phantom pain.
4. Radicular application: Ultrasound is applied to the corresponding spinal cord radix and then to the
manifested Head zone.
C) Contact between emitter head and body surface
1. Direct contact: Provided by a contact medium (a special gel for ultrasound therapy). This method is
considered customary, and it is therefore not necessary to mention it in an ultrasound therapy prescription. However, because paraffin oil does not conduct electricity, it is useful to use a "conductive gel" for an ultrasound therapy when giving combined therapy (ultrasound + electrotherapy).
2. Subaqual emission:
Advantages: Subaqual emission employs most of the distant ultrasonic field so that risk of interference is almost eliminated. In addition, there is no need to apply emitter head pressure against the skin in order to maintain sufficient contact (the pressure is unpleasant or even painful for a post-trauma patient). Ultrasound can be applied to interphalangeal joints as well with this method, because treatment is not limited by uneven surfaces. Disadvantages: Cumbersome and difficult handling of the special porcelain tanks. Ultrasound application is limited to acral the body parts. The therapist also risks lesions to the hands if precautions against dipping them into the water tank during therapy are not followed (due to reflection and interference of the ultrasonic waves). Some emitter heads (newer ones included) are advertised as water resistant, but neither feature a holder nor provide a safe subaqual ultrasound treatment. Ultrasound application through a thin-walled rubber bag (surgical gloves, condom) full of previously boiled water may be a solution. However, this method makes it
page 12
BTL – 07p operating manual & user's guide
necessary to eliminate even a minimal air gap between the skin, the bag and the emitter head by using vaseline or paraffin oil, often considered unnecessarily time-consuming.
Ultrasound frequency
Older instruments operate at a fixed frequency, usually 0.8 - 1 MHz. Newer ones have a choice of frequencies. The level of frequency is determined by the affected tissue’s location (see above). A frequency of 1 MHz for deep tissues and 3 MHz for superficial tissues is recommended.
Modes of operation
A/ continuous ultrasound - predominantly deep heat generation in tissues. This form of ultrasound is contraindicated in inflamed areas and in cases where local warming of the tissue is undesirable. B/ pulse ultrasound - the shortened impulse time is followed by a decreased pulse-to-period ratio - PPR. As a result, the thermic effect is suppressed. With a PPR smaller than 1:8, an athermic effect can be expected.
The BTL-07p’s impulse time is shown by a proportional number. This number actually represents a fraction, which expresses a certain part of the ultrasonic emission period. With a pulse frequency of 100 Hz, the period time is 10 ms. A 1:4 PPR means that the impulse lasts 1/4 of the period (2.5 ms). A pause lasts the rest of the period (7.5 ms). 1:8 PPR - the impulse lasts 1.25 ms (1/8 of 10 ms) and the pause 8.75 ms. With a pulse frequency of 50 Hz, the period is 20 ms long. 1:4 PPR - the impulse time is 5 ms (1/4 of 20 ms), pause 15 ms. 1:16 PPR - the impulse time is 1.25 ms (1/16 of 20 ms), pause 18.75 ms.
Emitter head size
The emitter head size determines the effective radiating area - ERA 1 cm
2
(small) and 4 cm
2
(medium - although some producers consider it large). The choice of emitter head size is determined by the size of the application site. Ultrasound emission to large areas is difficult for the therapist, lasts too long, and the dose is not applied consistently. Small ERA 1 cm
2
emitter heads are used either to manage trigger points and scars or to manage small, uneven
surfaces which have to be treated by the subaqual method if the emitter head size is large.
Application time
Individual application times vary. They largely depend on the stage of the disease or condition. In acute states, an application lasts 3 minutes; in chronic states, 5 minutes. Application time is then extended using a positive step method. Application time usually must not exceed 10 minutes. When the application site area is x-times larger than the emitter head ERA, application time must be prolonged x-times. The dynamic method should be used.
Intensity
An intensity of 0.5 W/cm
0.2 W/cm

on the spasmodic fibres of m. temporalis. This muscle is situated just below the surface, on the bone. Since work is usually performed in a close ultrasonic field, a very low intensity is chosen. In chronic states, a 0.8 - 1.0 W/cm Using a positive step method and paying close attention to the patient’s reactions, the intensity is increased. Continuous ultrasound intensity must not exceed 2.0 W/cm

is used initially in acute states. In certain cases it is even lower - e.g. in trismus

intensity is initially used.
2
or a pulse ultrasound intensity of 3.0 W/cm2. It is not recommended to increase two parameters at the same time. If application time is extended, do not increase intensity. If intensity is increased, do not extend application time.
Procedure frequency
For acute cases: 5 times a week. For chronic cases: 3 times a week. In some cases it is suitable to change the procedure frequency during the treatment process (e.g. 3 times a day, 3 times every second day).
Total number of treatments
The total number of treatments varies according to individual circumstances, and can range from a single application prior to myosceletal surgery to 9 applications over a 3-week period for chronic states.

Specific contraindications of ultrasonic therapy
A) Absolute
Epiphysis of growing bones Ultrasound patients risk irreversible growth zone damage, deformity and/or permanent disablement. Since older types of ultrasound instruments operate at low intensities (displayed data does not correspond with the actual amount of the energy applied), their use does not lead, in most cases, to growth zone damage. For this reason, many physicians disagree with this contraindication. Modern stronger and more effective instruments can, in contrast with the older ones, cause actual growth zone damage, especially when the emitter is not moved sufficiently. Prevention of this contraindication is the absolute responsibility of the prescribing physician and the ultrasound therapist.
Gonads Small doses result in transient and high doses in permanent spermio- or ovogenesis impairment.
Eyes The use of opthalmic ultrasound instruments is restricted to specialized centers. Physiotherapy must follow the above-mentioned contraindication.
St. P. laminectomy
Since the spinal cord is not completely covered by an osseous cover after laminectomy, ultrasound application to the medulla may result in transient or permanent paraparesis DK (when the axons of the spinal cord paths are disorganized). This is one of the most serious negative effects of physiotherapy.
New bleeding (anywhere)
Since ultrasound waves spread considerably via humours during ultrasound therapy, various side-effects may occur in spite of the lowered wave energy. For example, by applying ultrasound to a knee, refractory epistaxis can re-occur.
B) Relative
Brain, Heart, Parenchymatous Organs
There is no reason to apply ultrasound to these organs. In addition, the brain is covered by the cranium. However, an article was published about a person who irradiated his sinuses while applying ultrasound to his own knee. This patient died because of massive bleeding in the forehead lobe, as the calcified atheroma plate was disturbed. It is widely believed that this was not an accident. This information is included only as a strong reminder to the therapist that ultrasound is not to be used in these areas. A patient must never apply ultrasound to himself or herself, even if the application site can be reached easily.
Peripheral Nerves (situated just below the surface, on the bone) This group includes: n. ulnaris in the elbow area, volar areas of the wrist, inguines, the areas under the external and internal ankles, etc. As a result of constructive interference (stationary waves), local intensity peaks occur in all of the above­mentioned areas. Intensity peaks lead to impulse flow speed prolongation and irreversible destruction of nerve fibres. Muscular fibres and myelin covers of the damaged nerves are usually preserved.
Bone projections just under the skin: - spinous projections of the spondyles, ankles, condyles, and epicondyles.
This is again a commonly ignored contraindication. Many experts consider ultrasonic therapy to be an epicondylitis treatment. This is only true insofar as ultrasound application to a corresponding muscular group (extensoric if lateral, flexoric if there is ulnar epicondylitis) is also taking place. Direct ultrasound application to a painful attachment often leads to increased pain, but more often leads to the process of chronification (the same effect as that of numerous massive local corticosteroid applications). Similarly, the application of ultrasound directly to the spine often results in refractory periosteum pain around spinal projections.
Emphysema, Bronchiectasis (via ultrasound therapy on the chest) Menses
This contraindication is considered absolute as far as the hypogastrium area is concerned. Before ultrasound is applied to a different area, the patient should be told that intensity of menstruation might increase (more often in menstruation acceleration than in the form of metrorrhagia). If the anamnesis shows that an ultrasound application may adversely affect menstruation, the therapist should refuse to carry out the procedure and suggest that the patient consult her physician.

Facultative features of the prescription
Patient's position, contact medium, additional information for the physiotherapist.
Instructions for a patient
Ultrasound therapy is mostly asymptomatic, but a sensation of moderate heat or warmth may be felt in the treated area. A burning sensation on the skin during therapy indicates insufficient contact. Pain during application indicates either an overdose or insufficient movement of the emitter head. In the case of an overdose, stop the procedure immediately and inform prescribing physician. Therapy can be resumed at a lower intensity, usually after a one-day break. After the first treatment, a transient deterioration of the disease may occur. A marked improvement should occur not later than the third application. If there is no improvement (in acute and subacute states), ultrasound therapy should not be continued. If ultrasound therapy is applied to chronic processes (which rarely happens) or to change the mechanical qualities of tissues (e.g., Dupuytren's contracture or plantar aponeurosis related to calcar calcanei), impressive results cannot be expected by the third application. If ultrasound therapy is not immediately followed by a manual therapy, results should not be expected, even after the tenth application.
Procedure
1. Inform the patient about the procedure. NEVER LET PATIENTS APPLY THE ULTRASOUND
TO THEMSELVES!
2. It is unnecessary to inform patients about rare contraindications unless such information is specifically
requested. However, be sure to ask if epistaxis is present or if patient is menstruating.
3. Place the patient in the proper position for the therapy.
4. Use a sufficient amount of the appropriate contact medium.
5. Set the prescribed intensity and time, apply the emitter head, and switch on the ultrasound.
6. Move the emitter head continuously in accordance with the prescribed application.
7. Repeatedly ask the patient about his or her sensations. If he or she feels a burning sensation, add more
contact medium. If pain occurs, lower the intensity. If necessary, interrupt the procedure and inform the prescribing physician.
8. After the prescribed time has elapsed, lower the intensity and switch the instrument off. Most instruments
switch off automatically.
9. Clean the contact medium off the patient and dry the skin.

(A subacute process usually calls for a lower intensity. However, in this case, the use of pulse ultrasound is most important with a distant ultrasonic field where intensity is at least two times lower). Application time: 6 minutes. Irradiated area is approximately twice larger than the emitter head ERA. The shortest time for acute states is twice 3 minutes. Since intensity increases in increments, length of time should not. Frequency of procedures: At first, three procedures daily, after that every second day. As the condition changes from subacute to subchronic, pauses between procedures are lengthened in order to give the organism a better opportunity to heal itself. Total number of procedures: 5

Combined therapy
Combined therapy is the application of two or more kinds of energy. Classic diadynamic currents comprised of simultaneous low frequency galvanic and pulse currents are also considered a form of combined therapy.The procedure generally includes the following combinations: ultrasound + low frequency currents ultrasound + amplitude modulated mid-frequency currents ultrasound + TENS
Ultrasound and low frequency currents
Can be used with one unit or by connecting two separate units (BTL-06 + BTL-07p). The desired current with an adjustable intensity should be brought to the emitter head. The other electrode is placed opposite the emitter head so that the ultrasound field and the low frequency current are both located in the treatment area.
Mechanism of action
The myorelaxation is effective, if the proper frequency (100 - 200 Hz) is used. The combined therapy with a 3 MHz ultrasound frequency is suitable especially for treating the located myospasm, uncoordinated muscle fibres and the trigger points. The risk of galvanic effect is heightened. It can be seen on the emitter head rather than on the skin. To guarantee the patient’s safety it is necessary to be aware of this, especially if higher frequencies are used.
Application time
Usually 3 - 6 minutes. The application time can be extended with the positive step method. In acute states or in cases when the treatment area is small, the length of the therapy should be reduced.
Intensity
Set the ultrasound intensity at 0.5 - 0.7 W/cm
2
for continuous ultrasound and at a max. 1.0 W/cm2 for a pulse ultrasound with 1:2 PPR or greater. Set the low frequency component intensity according to the object. When searching for the trigger points, set the threshold sensitive intensity outside the area where reflex changes are expected and with this intensity try to get as close as possible to the area. The intensity will be above threshold sensitive in a hyperalgeic zone, and the patient may even feel pain. The threshold motor and above threshold motor pre-set intensity evokes a motor response. If the pain threshold is not reached, use the same intensity for the therapy. Otherwise adjust the low frequency component intensity according to the current used and effect desired. The size of the indifferent desk electrode should be 2x - 10x larger so that the sensitivities are located on the ultrasound margin.
Total number of procedures
A total of 2 - 3 treatments is recommended, based on the indication + effect. Five or more treatments are recommended only in special cases.
Frequency of procedures
Daily or as a pre-medication (postisometric relaxation-PPR).

Indifferent electrode at least 6 x 6 cm on the right forearm flexors Application time: 4 minutes Number of treatments: 3, daily application
Ultrasound + amplitude modulated mid-frequency currents
The mid-frequency currents have no galvanic effects,and better tolerance. They have a deeper effect hence can be used for changing reflexes in deep muscles. Use a 1 MHz ultrasound frequency when treating deeply underlying muscles. The combination of the BTL-06 and BTL-07p offers a selection of ultrasound parameters and amplitude modulations Hence these currents can be used for surface muscles (at a 3 MHz frequency) as well as deep muscles (at a 1 MHz frequency)
Mechanism of action
Same as the ultrasound/electrotherapy combination (see above). Optimal myorelaxation is attained at 150 - 180 Hz frequencies (The effectiveness of myorelaxation, unlike that of diadynamic current, is not lowered by a 50 Hz frequency. (MF - DD current). Use the continuous ultrasound if improving the myorelaxation by increasing the temperature. If you want to point out the micro-massage or if hyperthermia is not indicated, use the pulse ultrasound.
Application time
3 - 10 minutes. Using the positive step method after 1 minute is recommended. The application time for the semistatic method refers to the affected area, whose surface is equal to the emitter head ERA. The application time for dynamic method should be x times longer because the affected area is x times larger than the emitter head ERA. An initial intensity of 0.4 - 0.6 W/cm intensity 0.5 - 1.0 W/cm

is used for continuous ultrasound (1:1 PPR). For 1:2 - 1:4 PPR use the
The AMP intensity is chosen according to the effect. The above threshold sensitive intensity principally has an 100 Hz amplitude modulation analgetic effect. Use the threshold motor intensity for an optimum myorelaxation modulation 150 - 180 Hz effect. The patient should not feel any pain or burning in hyperallergenic zones or at trigger points during the application. If the application becomes painful, set the lower ultrasound intensity (include this in the patient‘s medical record and make sure the patient‘s doctor does an immediate check-up on the patient). If a burning sensation is felt on the trigger point, set the lower mid-frequency component intensity, add the desired contact medium (it is not necessary to inform the patient‘s doctor).
Number of procedures
Usually 3 - 6 treatments. Written justification must be given in the patient‘s medical record for a greater number of treatments. Three applications are recommended for a status acutus in deeply lying muscles. More applications for usual status subacutus or subchronicus. Therapy may be continued if the effect is good and no causal therapy is available.
Procedure frequency
Apply daily for status acutus. For status subchronicus the frequency may be changed within one cure period (3 times a day, later 3 times every second day).
Procedure prescription
Same as the ultrasound/electrotherapy combination (see above).

Ultrasound + TENS (transcutaneous electrostimulation)
While emphasis was placed on myorelaxation, therapy of hyperalgetic zones and trigger points in the aforementioned types of combined therapy, a combined US and TENS treatment is applied as a general analgesic, not only for the above mentioned reflex changes but also for other kinds of pains. In these cases, we recommend that you review the list of pains that ultrasound can treat because not every pain can be treated with an ultrasound. The combined US and TENS treatment can be used for myalgia (post-injury, reflexive, etc.), post­traumatic pain (after 24 - 36 hours), lege artis during the whole therapy (relaxation, decompression, etc.) The preferred TENS impulses are symmetric biphasal or alternating biphasal impulses - program numbers 10, 11, 13, 14, 16, and 17 (the galvanic effect is omitted). When the degree of pain is small, use continual (conventional) or random TENS; when the degree of pain is greater, use a basic TENS 100 Hz frequency and 2-8 Hz burst frequency. The intensity should always be as high as the patient can stand it. This combination will have a faster effect than other sequential procedures. However, it is important to keep in mind all the contraindications for ultrasound (see Operator’s Manual - Ultrasound).
Mechanism of action
Reducing the perception of pain positively affects the trophic in the injured area. The simultaneous ultrasound application followed by increased capillary permeability, improved extravasal liquid absorbtion, increased vasoactive amines secretion and the influence on the pre-capillar spfincters are considered the most effective prevention against the algodystrophic syndrom. Physical therapy in the porouses area is contraindicated. Use the segmental method only for trophicus.
Application time
Status acutus : 3 - 5 minutes. Status subacutus : 3 - 10 minutes (you may use the positive step method).
Intensity
The ultrasound intensity - see above. The continuous TENS intensity abovethreshold sensitive - at the highest tolerable level, TENS burst at highest tolerable level. Use the TENS surge with the above threshold motor intensity for the trigger points or application to spastic muscles.
Total number of treatments
Individual, usually 1 - 6 treatments in one therapy.
Frequency of treatment
Usually daily application. In selected cases, every second day as the sessions come to an end. In segemental long term treatments(sy. Sudeck, for example)., we recommend ending the therapy by slowly decreasing the frequency of treatments (three times a week, twice a week, once a week and then ending the therapy

. Electrotherapy: TENS continuous, imp. 0.05 ms, asymmetrically biphase, f = 100 Hz, (program 1525) Procedure: First apply contact gel (electrically conductive) to the examined area. Set the ultrasound parameters.
Outside the hyper-allergic zone (HAZ) or the assumed trigger (TP) set the intensity of the electrical to threshold sensitive and through a fluent head movement we move to the assumed and reflective changed area. HAZ is announced by the patient as a increased intensity of a feeling by electric current bypass. TP localisation can be found in two ways:
1. The patient reports a typical radiating pain.
2. Asymptotic motor effect (muscle contraction) in the affected muscle.

Note the current intensity in mA, causing the reaction.
B/ TP treatment
Without moving the head, change the PPR to 1:2, maintaining the original intensity and using either a semi­stationary or a stationary method to apply the combined therapy directly to the TP for 1 - 3 minutes. There must be no standing waving - acoustic and optical indication. All parameters of the electric component, only if there is a lowered intensity (the patient stops perceiving the current), increase it and maintain it at a threshold sensitive.
C/ Therapy effect control
Set identical parameters as in A including the current intensity and move the head as in A. If the therapy is successful the original TP will no longer exist. Otherwise, repeat the B procedure.
If a palpably or clinically diagnosed trigger cannot be detected by the method described in A, repeat the whole procedure with the ultrasound intensity increasing by 0.1 W/cm
