EMS- Electrical Muscle Stimulation - Relaxation of muscle spasm - Increasing local blood circulation - Muscle re-education - Prevention or retardation of disuse atrophy - Prevention of venous thrombosis of the calf muscles immediately after surgery - Maintaining or increase range of motion

Device Story

TENS-EMS-14 is a combination transcutaneous electrical nerve stimulator and electrical muscle stimulator. Device delivers adjustable electrical current waveforms to patient skin via 2 or 4 electrodes. Powered by 4 AA batteries; features 2 output channels. Includes patient compliance timer capable of storing 60 operation records (up to 999 hours). Used by patients under physician prescription for pain management and muscle therapy. Healthcare providers use device output to treat muscle spasms, improve circulation, and prevent atrophy. Benefits include non-invasive pain relief and physical rehabilitation support.

Clinical Evidence

Bench testing only. Performance testing included output measurements, calculations, and safety inspections for electrical leakage current, electrode/lead wire safety, and output power density. Electromagnetic compatibility testing was performed in accordance with IEC 60601-1-2.

Technological Characteristics

Battery-powered (4 AA) electrical stimulator. Features 2 output channels for 2 or 4 electrodes. Adjustable waveforms and output parameters. Compliance timer for record-keeping. Tested per IEC 60601-1-2 for electromagnetic compatibility.

Indications for Use

Indicated for patients requiring symptomatic relief of chronic intractable pain, post-traumatic/post-surgical pain, muscle spasm relaxation, local blood circulation improvement, muscle re-education, prevention/retardation of disuse atrophy, prevention of post-surgical calf muscle venous thrombosis, and maintenance/increase of range of motion.

Regulatory Classification

Identification

A transcutaneous electrical nerve stimulator for pain relief is a device used to apply an electrical current to electrodes on a patient's skin to treat pain.

Device Description: The TENS-EMS-14 is a combination TENS and EMS device which delivers nerve or muscle stimulation by applying an electrical current to electrodes, which are attached on the patient's skin. The output and waveform is adjustable according to the intended treatment of patient. The stimulator has 2 output channels, accessed through jacks at the top of the housing, so that it may stimulate either 2 or 4 patient electrodes. The device is powered by 4 AA batteries. A patient compliance timer can memorize 60 sets of operation records; the total recordable time is 999 hours.

Intended Use: As prescribed by a physician for the following:

#### TENS- Transcutaneous Nerve Stimulation

- . Symptomatic relief of chronic intractable pain
- Post traumatic and post surgical pain relief .

### EMS- Electrical Muscle Stimulation

- . Relaxation of muscle spasm
- . Increasing local blood circulation
- . Muscle re-education
- . Prevention or retardation of disuse atrophy
- . Prevention of venous thrombosis of the calf muscles immediately after surgery
- . Maintaining or increase range of motion

Discussion of performance testing: Based on the output measurements, calculations, and safety testing/inspection; the TENS-EMS-14 is safe with respect to electrical leakage current, electrode and lead wire safety, as well as output current and power density. Testing performed in accordance with the accepted FDA requirements of IEC 60601-1-2, Medical Electrical Equipment, Part 1: General Requirements for Safety. Collateral Standard: Electromagnetic Compatibility- Requirements and Test, found the TENS-EMS-14 passed all of the applicable test.

#### Technological Characteristics and Substantial Equivalence

Output specifications, device design, waveforms and programmability demonstrated the TENS-EMS-14 to be substantially equivalent to the predicate device.
