Muscle stimulating currents, including Bio-stim, to improve awareness and strength in individual muscles that are weakened due to pain (and therefore disuse and lack of co-ordination occurs) and as a result this improves mobility. It is applied in: disuse atrophy (may even be used in the elderly to improve frailty and co-ordination); increasing and maintaining range of motion; and muscle re-education and facilitation. It will reduce the duration of the rehabilitation, thus impacting on health care costs and returning the patient to gainful employment or independence.
