1. INTRODUCTION

Designed specifically for rehabilitation and retraining of gait for patients with neurologic and
orthopedic gait dysfunctions, the Biodex Gait Trainer 2 provides both the audio and visual feed-

ack needed to progress patients quickly and safely to normal ambulation.

b

The Gait Trainer 2 is easy to use. The clinician need only select the patient’s age and height for the
treadmill to automatically calculate the exact speed needed to achieve desired step cycle. The
rhythmic movement and the audio feedback provide patients with added stimulus for retraining
of neural pathways to improve gait pattern.

The Gait Trainer 2 promotes correct stride length for early phase patients. By starting out slowly
(with the zero starting speed and small .1 step cycle speed increments) it is possible to manually
position the patient’s lower extremities in the desired patterns for gait, thus reinforcing the prop­er techniques early in the rehabilitation process. As the patient progresses, correct stride length is
coupled to the correct step cycle. When belt speed is increased, the patient must either take longer
strides or more strides to stay on target. Normative data allows clinicians to compare patient
progress to baseline norms.

Of course, the Gait Trainer 2 can also be used for many other rehabilitation treadmill applications.
In treadmill mode, its unparalleled speed control, durability, incline and decline in both forward
and reverse directions, digital feedback, low profile, and choice of handrail configurations make
it the ideal choice for virtually any patient young or old.

The Biodex Gait Trainer 2 comes with a printer which is easy to install and resides on the printer
stand. Options include -3 to 12% incline/decline (ideal for work with back, posture, lumbar spine
and patella patients,) and a choice of handrails.

2. CLINICAL CONSIDERATIONS FOR GENERAL USE

The following clinical considerations should be observed for all patients who exercise on the
Biodex Gait Trainer 2. Additional clinical considerations, specific to gait training, are provided in

he chapter titled: Clinical Applications and References.

t

1. All patients should consult a physician before beginning any rehabilitation program.

2. Instruct patient on proper use and all Gait Trainer 2 safety features before beginning exercise.

3. Always attach the Safety Lanyard to the patient’s clothing or wrist before allowing exercise to begin.

4. Ensure patient has stretched and warmed-up prior to starting exercise.

5. Do not allow any patient to exercise unattended on the Gait Trainer 2. Never leave the Gait Trainer 2
running unattended.

6. Periodically monitor the heart rate of patients exercising on the Gait Trainer 2.

7. Begin all exercise at a slow pace, increasing speed gradually to patient tolerance and progressing toward
exercise goals. Always inform the patient immediately prior to increasing or decreasing speed or eleva­tion.

8. If reversing belt direction, bring the Gait Trainer 2 to a complete stop and inform patient that the belt
will begin moving in the opposite direction.

9. Immediately discontinue exercise if patient feels faint, dizzy or short of breath.

10. Never allow anyone to step onto the Gait Trainer 2 while the treadbelt is in motion. Always stop the
Gait Trainer 2 prior to allowing the patient to step up onto the treadbelt.

11. Instruct patients to use the handrails when first learning to walk on the Gait Trainer 2.

1. Tous les patients doivent voir leur médecin responsable avant d’entreprendre la séance de rééducation.

2. Expliquer au patient la bonne utilisation des systémes de sécurité du tapis avant de démarrer la séance.

3. Connector toujours la sangle de sécurité aux vêtements du patient ou poignet avant que le patient ne
commence à travailler.

4. Vérifier que la patient s’est échauffé et a fait des étirements avant de commencer l’entraînement sur le
tapis.

5. Ne pas laisser le patient seul sur le tapis pendant la séance. Ne jamais laisser le tapis tourner sans
patient et sans surveillance.

6. Surveiller de temps à autre la fréquence cardiaque du patient pendant la séance.

7. Démarrer les protocloes à une vitesse lente et augmenter progressivement la vitesse en fonction de la
tolérance du patient et progres uers les objectifs de la séance. Signaler avant de l’appliquer tonte aug­mentation ou diminution de vitesse ou d’inclinaison.

8. Avant de changer la direction de déplacement du tapis, arrêter le tapis complétement et expliquer au
patient que le tapis va démarrer dans le sens opposé.

9. Arrêter la séance immédiatement en cas de dyspnée, d’étourdissements ou d’autres signes de malaise.

10.

Ne jamais faire monter personne sur le tapis pendant que le tapis est en marche. Arrêter toujours le
tapis avant que le patient ne s’y positionne.

11. Donner la consigne au patient d’utiliser les barres horizontales lors de sa premiére séance sur le tapis.

4. GAIT TRAINING MODE

The Biodex Gait Trainer 2 can be used for gait training applications, or as a rehabilitation tread­mill. The following section describes use in the Gait Training Mode. Rehabilitation treadmill oper-

tion is described later in this manual.

a

THE GAIT TRAINING MODE

The Gait Training Mode is useful for the rehabilitation and retraining of gait for patients with neu­ralgic and orthopedic gait dysfunctions. It provides both audio and visual feedback for patient
compliance. The rhythmic movement of the treadbelt along with the audio and visual biofeed­back, provides the necessary stimulus for retraining neural pathways, thus improving the gait pat­tern of the patient.

NOTE: It is recommended that the Biodex Unweighing System be used in conjunction with the Gait Trainer
2 to provide a safe environment for the patient and clinician, and also to allow for proper patient position­ing for weight distribution and coordination of balance.

POWER-UP

(See Figure 4.1)

To provide power to the Gait Trainer 2, ensure the power plug is connected to an appropriate sock­et. Press the ON/OFF switch, located on the base of the Gait Trainer 2 in the left corner at the front

• Speed (Cycles/Second): Located at the top right of the screen. Use the associated ▲ and ▼ icons

to set this goal to match the desired cycles per second.

The step cycle default is 0.10 cycles/sec and the range is 0.1 to 5 cycles/sec. This parameter, in
conjunction with the patient’s height, is used to determine belt speed (since walking speed is
determined by step length and step cycle) and is important for developing proper gait patterns.
Changing either the step cycle or target step length will cause the speed of the belt to increase
or decrease. The initial starting speed of 0.1 cycles/sec can easily be adjusted during the exer­cise session by using the

NOTE: For visual and audio biofeedback, the treadbelt speed must be greater than 0.8 mph (0.9 kmh, or

0.34 meters/second).

The cycle/sec speed and/or step length regulate the treadbelt speed. If treadbelt speed is below 0.8 mph
(0.9 kmh, or 0.34 meters/second) a message will display noting that the treadbelt is moving too slowly

miles, meters and kilometers.

• Speed (Treadbelt Speed): Located at the top left of the screen, touch the solid yellow dot <o>, to

toggle units of measure between KMH, MPH and meters/second.

• Heart Rate: Heart rate monitoring is accomplished by having the subject hold onto both heart

rate handgrips on the front handrail. The heart rate value will be displayed at the top left of the
screen when the handgrips are held.

• Histogram or Footfall: Located at the bottom left of the screen, touch the desired icon to toggle

between these two choices.

Footfalls: Displays alternating right and left targets in the shape of feet. When the patient’s
actual footfalls are detected they are displayed with respect to the target. When the patient falls
within the set standard deviation the footfalls are synchronized with the targets and are told
“good job” by the display. Should they fall outside of the SD the footfalls and targets are out
of synch the display will tell the patient which footfall is outside of the standard deviation by
pr

ompting them to go longer or shorter on the respected foot.

Histogram: Displays footfalls as a 2-pixel wide dot. The X-axis shows distance traveled in
meters and the Y-axis shows the deviation, where 1 pixel is equal to 1cm of deviation. If the
patient goes beyond the SD, the histogram will deviate from straight path.

NOTE: On the histogram graph, the upper and lower lines are the target step lengths plus/minus the
standard deviation. You will notice that the upper line and lower line are equal to the range of the aver­age step length.

5. NORMATIVE DATA

(Refer to Tables A1 and A2.)

he normative data charts provided in this manual can be used to develop rehabilitation pro-

T
grams and discharge criteria for your patients. The normative values are based on age and gen­der so comparisons can be easily made.

NOTE: Clarification of Normative Data for the Gait Trainer 2: The normative data presented in the Biodex
Gait Trainer 2 id derived from the reference tables in
Michael W. Whittle, 1997, pgs. 218-219.

Cycle time in Whittle is seconds, whereas the Gait Trainer uses cycles/second. Therefore, data is presented
as the inverse function of the cycle time:

Gait Analysis, An Introduction, 2nd. Edition,

Cycles per second = Cycles

Whittle also presents normative data for stride length. The Gait Trainer 2 uses step length. A stride equals
two steps, therefore, these tables represent stride length divided by two.

— 5-1 — NORMATIVE DATA

6. GAIT TRAINER OPERATION

GAIT TRAINER 2 THEORY OF OPERATION

1. Walking (gait) speed can be increased two ways: Increase step frequency (step cycle) or
increase step length.

2. Step cycle: A successive heel strike for the same foot, i.e. Right step, left step, right step. Can
be used to set belt speed based on how many complete successive heel strikes occur within a

econd. .1 cycle per second is very slow, 3 cycles per second is fast. Normal walking step cycle

s
approximates 1 cycle per second.

3. Step Target: A theoretical footfall area based on calculated step length. When step target dis­tance is increased, belt moves faster as steps need to become longer. If target distance is
decreased, belt speed decreases, as steps need to become shorter.

4. Step Length : Is a range [Leg length (cm) x .69] to [Leg length (cm) x .86]. Step Target is placed
within this range plus or minus the entered standard deviation.

5. In Footfall display: Standard deviation is used to prompt walker if they need to go faster on
either right or left side, or both sides. If footfalls occur within standard deviation they are told
good job.

6. In Histogram display: Standard deviation is bandwidth of where step footfalls should occur.
Normal healthy walking at a comfortable pace exhibits step lengths within 3 cm.

GAIT TRAINER 2 OPERATION

At this point, you should be ready to begin gait training using the following procedure:

1. Press the ON/OFF switch, located on the base of the Gait Trainer 2 in the left corner at the
front end, to the “l” (ON) position. The orange LED on the <ON/STANDBY> key, located at

Distance: The distance covered in miles or KM from the beginning to the end of the current exer­cise session.

Calories: Toggle between:

• Calories: Total calories burned by the user during the current exercise session. This value is dis-

played in real-time.

• Calories/Hr: Total calories that will be burned in one hour if exercise continues at the current

rate. This parameter is dependent upon a default weight of 150 pounds.

• METs: This value reflects the resting rate of Oxygen consumption with one MET equal to the

Oxygen consumption of a seated individual at rest. Thus, a seated individual in a resting state is
consuming one MET. A seated individual exercising at a rate of two METs is consuming twice the
Oxygen of a seated, resting individual. A person exercising at 10 METs is consuming ten times the
Oxygen of a seated, resting individual. To compute the METs of a person actively exercising on
the Gait Trainer 2, the system uses standard calculations based on American College of Sports
Medicine Guidelines for Testing and Exercise. The METs value is always displayed in real/time
for current speed.

Pace: The amount of time it will take the user to move one mile or KM at the current treadbelt
speed.

Heart Rate: This is the real-time heart rate of the user during the exercise session measured using
the contact handgrips.

QUARTERLY MAINTENANCE
Lubricate Treadbelt and Slider Deck

The Biodex Lubricant Kit is designed to reduce friction between the treadbelt and the slider deck.
It is required for all institutional treadmills. Proper and timely application of the lubricant will
prevent premature failures due to excessive wear and load. Items affected by inadequate lubrica­tion are the treadbelt, slider deck, motor, and motor controller.

angle iron brackets attached by securing nuts, and four running deck support bars secured by
Allen screws. Once all support brackets are removed the treadbelt can be removed.

10. Tension treadbelt and adjust tracking after you reassemble the Gait Trainer. (See Treadbelt
Adjustment procedure.)

Treadbelt Adjustment

Although the Gait Trainer incorporates the “Exact Track System,” occasional belt adjustments are
still necessary for correct tensioning and tracking.

Tension Adjustment

CAUTION: Before testing treadbelt tension as described below, turn the Gait Trainer OFF and
unplug the system. Moving parts on the Gait Trainer can cause serious injury. Do not attempt to
determine treadbelt tension while the belt is moving.

ATTENTION: Avant de tester la tension du tapis selon la procédure décrite ci-dessons, méttre le
tapis à l’arrêt et déconnecter le câble secteur
blessures graves. Ne jamais essayer de déterminer la tension sur le tapis pendant que ce dernier est
en mouvement.

The need for tension adjustment is indicated by uneven belt speed or the belt stopping suddenly
upon foot impact. Properly tensioned, the treadbelt will allow the user to slip a hand snugly under
the center of the belt.

Treadbelt tension is adjusted by tightening or loosening the two hex-head, 9/16, bolts at the end of

amount, in the same direction. Turn both bolts clockwise to tighten the belt. Turn both bolts coun­terclockwise to loosen the belt. Failure to turn both bolts equally may affect tracking. One quick test
is to apply hand heel strikes and observe if belt momentarily stops. If belt speed remains constant,
this indicates belt is tight. If belt hesitates during heel strikes, additional tightening is required. To
check over tightening, set Gait Trainer to .5 mph and, while holding rail, resist until belt stops. If

Tracking

racking adjustment is necessary when a pronounced bump appears toward the left side of the

T
belt, approximately two inches from the left edge. This occurs when the belt works its way out of

he Exact-Track grooves.

t

To Adjust Treadbelt Tracking:
Tighten the hex tensioning bolt on the side to which the treadbelt has migrated, turn bolt in 1/8
increments clockwise. The tread belt should slowly move away from the tightened bolt. Once belt
migrates back into roller slot the bump will disappear. At this point, fine tracking adjustment is
necessary.

Fine Tracking

Fine tracking adjustment prevents premature wear of the tacking belt rib which rides in the Exact­Track groove. The belt rib should be centered in the tracking groove. If the rib rides against the
groove wall, a friction point forms causing excessive wear. This adjustment should be made dur­ing preventative maintenance or during belt replacements.

To Adjust Fine Tracking:
Determine which side of the exact track groove the belt rib is riding on. Mark treadbelt tracking
position on deck.

Tighten the hex tensioning bolt on the side the belt is tracking against, belt should migrate to the
opposite side of the groove. Mark the treadbelt tracking position on the deck. You now have two
marks on the deck 1/4” apart. Mark the center position of the marks. This is where the belt should
track. Adjust 9/16 tensioning bolt so that the belt is centered on the mark. Remember the belt will
migrate away from the tension bolt that is adjusted last. Tracking adjustments are done in forward
direction only, at 8 mph.

Check tensioning after adjustment to ensure proper belt performance and wear.

NOTE: Motor drive belt should never slip. Check this when you check for treadbelt overtightening. If tread­belt drive roller is stopped, motor should also stall. If motor turns, but drive roller is stopped, tighten motor
tension bracket located under the mill. Adjust until the motor belt stops slipping.
