The Soken S-2000 is a versatile modality which allows the therapist/patient a means to comfortably stimulate and contract various muscle groups. Sokenís enhanced patient comfort is the result of the unique Soken waveform. This waveform is uniphasic and has a specific pulse duration which allows for effective stimulation with a minimal amount of output current, (0-25 milliamps in normal use). The Soken Electronic Muscle Stimulator is easy to operate and ideal for clinical or home use.

Mode Selector Settings:

#1. Constant High Frequency: Variable pulses per second (200 to 50pps.) dependent upon output

level for enhanced comfort.

#2. Intermittent High Frequency: Variable pulses per second (200 to 50pps) dependent upon output

level. "ON-Time" is 8 seconds followed by a rest cycle "OFF-TIME" of 2 seconds.

#3. Constant Low Frequency: 2 pulses per second.
