Muscle stimulation tennis device

Portable TENS device with four channels helps with neuro muscular electrical stimulation (NMES) which is sending electrical pulses to nerves resulting in muscle contraction. It can be applied during functional movement or without functional movement. It has been used over the years to strengthen muscles and maintain them and prevent atrophy especially with patients who do not move. Intended use of the portable TENS device with four channels: 1. Improve muscle strength and prevent muscle atrophy. 2. Improve the range of motion around the joint and maintain it. 3. Reduce muscle spasm and cramps. 4. Increase cardiovascular functions through activity of large muscle groups. Features of the portable TENS device with four channels: The device contains four channels, each channel has two electrodes. All four channels can be used or each channel can be used separately. Control of pulse strength and pulse shape is possible. The device contains several ready-made programs. Time can be set to control session duration. It operates on electrical current or batteries. It can be used as TENS or NMES. It operates with adhesive electrodes.
