It is not always possible to recover from muscle atrophy. It is important to see the cause of muscle atrophy to determine whether it can be restored to normal muscle strength. If a patient has neurogenic atrophy, recovery is generally relatively difficult. Muscle atrophy occurs when motor neurons are damaged, such as in patients with motor neuron disease, and this condition is relatively difficult to recover because motor neurons are nerves that are not renewable. If the patient’s muscle atrophy is caused by genetic factors, familial muscular dystrophy or the development of myositis or dermatomyositis, muscle atrophy occurs and is more difficult to recover. If the patient’s muscle atrophy is due to prolonged non-use, resulting in disuse atrophy, it is relatively well treated, attention to muscle rehabilitation, and with acupuncture, massage can help the recovery of muscle atrophy.
