The ST-304 Transcutaneous Electrical Nerve Stimulator is a wearable home-use device for adults with sore or aching muscles at the back of the neck. It provides temporary pain relief for strain associated with exercise or normal household and work activities. It is available over the counter.
Two fixed titanium electrode pads deliver low-frequency electrical pulses through intact neck skin. Users select either of two stimulation modes and adjust intensity through 15 levels. Conductive gel is applied to the pads before use. The default session lasts ten minutes.
Heat and Power
A separate heating mode provides a warming temperature of 32 to 38 degrees Celsius and can run alone or with stimulation. A rechargeable 3.7 V lithium battery powers the unit. The device cannot be used while charging, and manual buttons control power, mode, heat and intensity.
