Muscle StimulationSince the mid 18th Century, neuromuscular electrical stimulation (NMES) has been used as an adjunctive therapyfor various neuromuscular and musculoskeletal disorders. Clinicians and investigators have been successfully usingNMES to facilitate muscle contraction, to re-educate muscle action, to aid in the prevention of atrophy and toovercome neuromuscular inhibition following injury or surgery.a. Isometric Muscle StimulationNMES during isometric exercise offers a reduced threat of over-stress and re-injury to the joint. NMES is clinically used at themidpoint of the range of motion where the muscle can generatemaximum torque.Procedure:Gradually increase intensity to maximum patient tolerance during each contraction. The intensity should beincreased to produce at least 50 to 80% of Maximum Voluntary Contraction (MVC). Place ACP ReusableElectrodes in a bipolar or quadripolar pattern on the muscle(s) being stimulated. The treatment should beapproximately 15 minutes duration 3 to 4 times a week.b. Muscle Spasm ReductionNMES can be utilized to induce fatigue of muscles in spasm.Researchers have found that the greatest fatigue of muscles occurswhen the muscle contraction relaxation times are equivalent (1:1ratio) and when higher frequencies (60-80 Hz) are used. Electricalstimulation of the motor neuron using medium frequency currentsresults in neuromuscular junction fatigue.Procedure:Gradually increase intensity to maximum patient tolerance during each contraction. Place electrodes in amonopolar, bipolar or quadripolar pattern on the muscles in spasm. The treatment time should be ofapproximately 20 minutes duration repeated 2 or 3 times per week.c. Increased Blood Flow / Edema ReductionLong and short-term electrical stimulation of muscle has been shownto alter the vascular dynamics affecting local muscle blood andlymph flow. It has been shown that blood-flow increasedsignificantly during the first minute of electrical stimulation andremained elevated during and for ten minutes following stimulation.The immediacy of vasodilatation following electrical stimulationindicates that the vascular response is a functional, reflexiveresponse. In addition, long-term electrical stimulation has beenshown to increase the number of capillaries and thus improve thecapillary blood-flow to the stimulated muscle. Not all types andparameters of electrical stimulation affect the blood-flow dynamicsof the muscle being stimulated. Therefore, the following clinicalparameters should be adhered to for optimal effectiveness.Procedure:Place one or two sets of electrodes in a bipolar or quadripolartechnique over the selected muscle(s). Gradually increase intensityto 15 to 30% of maximum voluntary contractions. Continue thetreatment for approximately 10 minutes.Mode NMESTime ON 10 SecTime OFF 50 SecON Ramp 2 SecOFF Ramp 2 SecPulse Rate 35-50HzMode NMESTime ON 10 SecTime OFF 10 SecON Ramp 1-2 SecOFF Ramp 1-2 SecPulse Rate 35-50HzBlood FlowMode NMESSimultaneousTime ON 15 SecTime OFF 50 SecON Ramp 2 SecOFF Ramp 2 SecPulse Rate 50HzMuscle PumpEdema ReductionMode NMESAlternateTime ON 4 SecTime OFF 4 SecON Ramp 2 SecOFF Ramp 2 SecPulse Rate 35Hz
