System comprises stimulator unit, sequencer for channel selection, patient cables, and skin-applied electrodes. Device outputs various electrical waveforms to stimulate muscles. Patient controls signal intensity for comfort. Sequenced output allows bilateral or multi-region stimulation. Used in clinical settings under medical supervision for adjunctive therapy. Output affects muscle contraction to achieve therapeutic goals like spasm relaxation or atrophy prevention. ## Clinical Evidence Bench testing only. Testing included electrical safety, electromagnetic compatibility, and waveform performance. No clinical data provided. ## Technological Characteristics Transcutaneous electrical muscle stimulator. Features multi-channel sequencer, patient cables with shrouded connectors, and external electrodes. Energy source is electrical. Device is a standalone unit. Safety testing performed per standards for nerve and muscle stimulators. ## Regulatory Identification A powered muscle stimulator is an electrically powered device intended for medical purposes that repeatedly contracts muscles by passing electrical currents through electrodes contacting the affected body area. ## Predicate Devices - TAI SHENG Powered Muscle Stimulator, TS-166, ([K031310](/device/K031310.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Various types of waveforms may be output to generate the desired effect on the muscle(s) to be treated, and the patient is given control of the signal intensity for personal safety and comfort. Sequenced system may have more than on output channel in order to operate bilaterally on the body or to treat multiple regions simultaneously or serially in a prescribed sequence. Non-Clinical Tests The KS-138 has been tested in accordance with Submitted: applicable standards for medical device electrical electromagnetic compatibility, and safetv. the particular requirements for safety of nerve and muscle stimulators. > Accessories also meet safety requirements: 510(k) electrodes are specified, and the patient cable utilizes shrouded connectors to meet lead wire safety requirements. > System level testing including waveform testing was performed in combination the KS-138 stimulator. Clinical Tests Submitted: Conclusion: As the product description and tests as above, the new device: KINGLY STAR Powered Muscle Stimulator KS-138 is as safe and effective as, and the function in a manner equivalent to the predicate device: TAI SHENG Powered Muscle Stimulator TS-166. Thus the new device is substantially equivalent to the predicate devices in this aspect.
