Generally speaking, the length of time for which a TENS unit can be used on a regular basis depends on the type of condition being treated and the individual’s response to the treatment. Generally, a TENS unit can be used for up to one hour per day, but the duration can be extended based on individual need and comfort level.
It’s always best to consult a doctor beforehand, who can provide the best advice depending on an individual’s specific needs and medical history. Additionally, it’s important to note that one should not use a TENS machine for more than three to four hours in any given 24-hour period.
It’s also important to take a break after using the unit for an hour, since extended use beyond this recommended duration may lead to muscle fatigue, restlessness and inflammation.
