MULTI-MODALITY THERAPY USER MANUAL

Medium Frequency Alternating Current (MFAC)

Neuro-Muscular 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.



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.



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.



Increased Blood Flow

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.
