An electronic devise normally used to ease labour pains is being trialled on people with osteoarthritis.
Patients are to use a TENS machine, combined with exercise, as part of a trial being conducted across the West of England.

The machines send electrical impulses to muscles that override pain and distract from discomfort, making it easier to exercise. Almost half of all over-65s suffer from osteoarthritis.
