Abstract
A devise for trophic stimulation of muscles is provided. The device contains a pulse generation circuit that mimics the Motor Unit Action Potentials, MUAP's that are naturally generated when muscles are innervated. The invention provides the basic method for synthesizing the requisite waveform and provides the apparatus for the synthesis. Alternative pulse conditioning circuits are provided; one using a step-up transformer and one using pulse voltage multipliers. The resulting apparatus is safe, relatively painless to use and does not depend upon muscle contraction to achieve a therapeutic result.
Claims8
A device for trophic stimulation of muscles comprising:
- a. a pulse generator for generating electro-optical emitter signals that are an analog of Motor Unit Action Potentials that naturally occur in muscle contractions;
- b. a pulse conditioner for taking the output of said pulse generator and producing signals that are appropriate for the electrical simulation of muscles;
- c. at least two electrodes for applying the electrical output of said pulse conditioner to skin overlying the muscles to be simulated;
- d. a continuous low-rate firing activity that can be described mathematically as a delta function continuously pulsing at a slow base rate with interpulse intervals in a range of approximately 120 to 200 milliseconds;
- e. a superimposed rectangular-like rate modulation with exponential rise and fall, with T=20 to 40 milliseconds, changes said slow base rate into a burst of high rate pulses with short interpulse intervals in a range of about 10 to 20 milliseconds;
- wherein said high burst rate then declines exponentially into a slower rate with interpulse intervals of approximately 60 to 80 milliseconds, and, after approximately 500 milliseconds, decreases further to said slow rate of 120 to 200 milliseconds;
- and wherein said high rate burst modulation, as well as the entire cycle of rate changes described herein has an approximate recurrent period of 1 plus or minus 0.2 seconds;
- and
- f) a transformerless design using pulse voltage multiplication, wherein said pulse voltage multiplier circuit comprises cascaded transistors driving capacitors connected in series such that when said transistors are fired on, the output voltage is the sum of all the voltages stored in said capacitors.
A method of applying trophic stimulation to muscle fiber comprising generating and applying to the muscle fibres, or to ovelaying tissue, a stimulus pulse sequence, wherein the pulse sequence is analogous to the Motor Unit Action Potentials occurring naturally in muscle fibers, and comprising a continuous low-rate firing activity that can be described mathematically as a delta function continuously pulsing at a slow base rate with interpulse intervals in a range of approximately 120 to 200 milliseconds, and a superimposed rectangular-like rate modulation with exponential rise and fall, with T=2 to 40 milliseconds, changes said slow base rate into a burst of high rate pulses with short interpulse intervals in a range of about 10 to 20 milliseconds, wherein said high burst rate then declines exponentially into a slower rate with interpulse intervals of approximately 60 to 80 milliseconds, and, after aproximately 500 milliseconds, decreases further to said slow rate of 120 to 200 milliseconds, and wherein said high rate burst modulation, as well as the entire cycle of rate changes described herein has an approximate recurrent period of 1 plus or minus 0.2 seconds.
