1.1 What is a Neuromuscular Stimulator?

Neuromuscular Stimulation is achieved by sending small electrical impulses through the skin to the underlying motor
units (nerves and muscles) to create an involuntary muscle contraction.
Neuromuscular stimulation has many uses beyond its traditional application to prevent disuse atrophy, including:

●

An increased range of motion: As a substitute for passive stretching exercise performed by the patient or therapist.

●

Muscle re-education: for example, teaching patients how to set their quads.

1.2 How does a Neuromuscular Stimulator work?

Because the transdermal stimulation of nerves and muscles may be accomplished by electrical pulses, this modality
can help prevent disuse atrophy. Accordingly, incapacitated patients can receive therapeutic treatment to create
involuntary muscle contractions thereby improving and maintaining muscle tone without actual physical activity.

1.3 The Instrument:

The Neuromuscular Stimulator is an easy to use system. A marvel of miniaturized electronics, the lightweight power
unit transmits electrical pulses through the skin surface and stimulates motor units (nerve and muscles). The
electrical impulses are "ramped" so they closely emulate natural muscle contractions.

1. GENERAL INFORMATION

1

2.1 Caution:

Federal law (USA) restricts this device to sale by or on the order of practitioners licensed by the State in which they
practice to use or order the use of the device.

2.2 Indications:

This NMES is intended to be used in:

1. Relaxation of muscle spasm.

2. Prevention or retardation of disuse atrophy.

3. Increase local blood circulation.

4. Muscle re-education.

5. Immediate post surgical stimulation of calf muscles to prevent venous thrombosis.

6. Maintaining or increasing range of motion.

2.3 Warnings:

●

The long-term effects of chronic electrical stimulation are unknown.

●

Stimulation should not be applied over the carotid sinus nerves, particularly in patients with a known sensitivity to
the carotid sinus reflex.

●

Stimulation should not be applied over the neck or mouth. Severe spasm of the laryngeal and pharyngeal muscles
may occur and the contractions may be strong enough to close the airway or cause difficulty in breathing.

2. SAFETY

2

●

Stimulation should not be applied transthoracically in that the introduction of electrical current into the heart may
cause cardiac arrhythmias.

●

Stimulation should not be applied over swollen, infected, or inflamed areas or skin eruptions, (e.g., phlebitis, thrombophlebitis,

varicose veins, etc).

●

Stimulation should not be applied over, or in proximity to, cancerous lesions.

●

Keep electrodes separate during treatment. Electrodes in contact with each other could result in improper
stimulation or skin burns.

2.4 Precautions:

●

Safety of powered muscle stimulators for use during pregnancy has not been established.

●

Caution should be used for patients with suspected or diagnosed heart problems.

●

Caution should be used for patients with suspected or diagnosed epilepsy.

●

Caution should be used in the presence of the following:
a. When there is a tendency to hemorrhage following acute trauma or fracture
b. Following recent surgical procedures when muscle contraction may disrupt the healing process
c. Over the menstruating or pregnant uterus
d. Over areas of the skin which lack normal sensation.

●

Some patients may experience skin irritation or hypersensitivity due to the electrical stimulation or electrical
conductive medium. The irritation can usually be reduced by using an alternate conductive medium, or alternate
electrode placement.

3

●

Electrode placement and stimulation settings should be based on the guidance of the prescribing practitioner.

●

Stimulators should be kept out of the reach of children.

●

Stimulators should be used only with the leads and electrodes recommended for use by the manufacturer.

●

Machinery Operation: Patient should never operate potentially dangerous machinery such as power saws,
automobiles, etc. during stimulation.

2.5 Adverse Reactions:

●

Possible skin irritation or electrode burn under the electrodes may occur.

●

Possible allergic skin reaction to tape or gel may occur.

●

If the stimulation levels are uncomfortable or become uncomfortable, reduce the stimulation amplitude to a
comfortable level and contact your physician if problems persist.
