TENS Units
The first option has a distinct operating role: TENS Units apply low-voltage electrical pulses through surface electrodes to alter sensory input.
- This mechanism makes TENS Units relevant when the desired job matches that pathway.
- Within TENS versus massage comparison use, evaluate electrode placement, pulse settings, skin response, comfort, and task function.
- Its boundary is important because TENS does not strengthen muscle like dedicated stimulation or diagnose pain origin.
