A portable, hand-held, electrically-powered, digital instrument designed to assess neuromuscular function by measuring the force or power exerted by the back, chest, and/or leg muscles during flexion. It includes a force gauge, which may be attached to a handle or strap, to assess force generated during a variety of movements (e.g., leg abduction, lifting) and/or force required to be exerted by a clinician to overcome a patient’s resistance (break test techniques). Is typically used to test or control a patient's muscle strength as part of a rehabilitation program.
