Method of providing electrical stimulation of tissue
First Claim
1. A method of providing electrical stimulation of tissue comprising:
- generating a continuous train of repetitive pulses having a frequency in the range of 500 Hz to 100,000 Hz;
gating said pulse train to produce an output signal having intervals of continuous pulse train output alternated with intervals of no pulse train output in the frequency range of 0.1 to 200 Hz; and
delivering said output signal through electrodes to a tissue treatment area, said sequence of intervals of the pulse train output signal having a width of each successive interval different than the preceding and successive intervals.

Abstract
An electrotherapeutic method of providing electrical stimulation to human or animal tissue. A stimulating pulse train, having a primary frequency of 500 Hz to 100,000 Hz, is coupled to two electrodes attached to the portion of tissue to be stimulated. The train of pulses of the primary frequency are gated on and off so that they are applied and discontinued in predetermined intervals. For neural stimulation, the gating is performed at 0.1 Hz to 200 Hz. For muscle stimulation, the current is provided for predetermined intervals of 0.001 to 100 seconds and is discontinued in alternate intervals for 0.001 to 100 seconds. The stimulating pulse train may be amplitude modulated so that its amplitude rises at the beginning of each on-time period and falls at the end of each on-time period, the rise and fall time varying between 0.5% and 50% of the total on-time of the stimulating current.
