1. Muscle Stimulation

Since the mid 18th Century, neuromuscular electrical stimulation (NMES) has been used as an adjunctive therapy
for various neuromuscular and musculoskeletal disorders. Clinicians and investigators have been successfully using
NMES to facilitate muscle contraction, to re-educate muscle action, to aid in the prevention of atrophy and to
overcome neuromuscular inhibition following injury or surgery.

a. Isometric Muscle Stimulation

NMES during isometric exercise offers a reduced threat of over-stress

and re-injury to the joint. NMES is clinically used at the mid point of the
range of motion where the muscle can generate maximum torque.

Procedure:

Gradually increase intensity to maximum patient tolerance during
each contraction. The intensity should be increased to produce at least 50 to 80% of Maximum Voluntary
Contraction (MVC). Place ACP Reusable Electrodes in a bipolar or quadripolar pattern on the muscle(s)
being stimulated. The treatment should be approximately 15 minutes duration 3 to 4 times a week.

b. Muscle Spasm Reduction

NMES can be utilized to induce fatigue of muscles in spasm.
Researchers have found that the greatest fatigue of muscles occurs
when the muscle contraction relaxation times are equivalent (1:1
ratio) and when higher frequencies (60-80 Hz) are used. Electrical
stimulation of the motor neuron using medium frequency currents
results in neuromuscular junction fatigue.

Procedures:

Gradually increase intensity to maximum patient tolerance during each contraction. Place electrodes in a
monopolar, bipolar or quadripolar pattern on the muscles in spasm. The treatment time should be of
approximately 20 minutes duration repeated 2 or 3 times per week.

c. Increased Blood Flow / Edema Reduction

Long and short-term electrical stimulation of muscle has been shown to
alter the vascular dynamics affecting local muscle blood and lymph flow.
It has been shown that blood-flow increased significantly during the first
minute of electrical stimulation and remained elevated during and for ten
minutes following stimulation. The immediacy of vasodilatation following
electrical stimulation indicates that the vascular response is a functional,
reflexive response. In addition, long-term electrical stimulation has been
shown to increase the number of capillaries and thus improve the capillary
blood-flow to the stimulated muscle. Not all types and parameters of
electrical stimulation affect the blood-flow dynamics of the muscle being
stimulated. Therefore, the following clinical parameters should be adhered
to for optimal effectiveness.

Procedure:

Place one or two sets of electrodes in a bipolar or quadripolar
technique over the selected muscle(s). Gradually increase intensity to
15 to 30% of maximum voluntary contractions. Continue the treatment
for approximately 10 minutes.
