It can be also used for people with musculoskeletal pain such as long- term (chronic) back pain or knee joint arthritis.

You can use low frequency (<10 Hz) programmes on acupuncture points, to achieve similar effects to acupuncture.
TENS machines can be used alone for pain relief or be combined with other treatments. You can safely use TENS as long as it gives you pain relief. The effect may wear off after a few hours (this is called “accommodation”). If this happens, take a break of an hour or so before trying again.
