Muscle atrophy from intristic disease in an 18-year-old woman, weight 27 pounds (12.2 kg) Muscle atrophy from intristic disease in a 17-year-old girl with chronic rheumatism Muscle diseases, such as muscular dystrophy , amyotrophic lateral sclerosis (ALS), or myositis such as inclusion body myositis can cause muscle atrophy.
Spinal muscular atrophies (SMAs) are a genetically and clinically heterogeneous group of rare debilitating disorders characterised by the degeneration of lower motor neurons (neuronal cells situated in the anterior horn of the spinal cord) and subsequent atrophy (wasting) of various muscle groups in the body.

These paresthesias may be painful, such as shooting pain, burning, or a dull ache. They may also be pain-free, such as numbness or tingling. Motor nerve entrapment may present with muscle weakness or paralysis for voluntary movements of the innervated muscles. Entrapment of certain pelvic nerves can cause incontinence and/or sexual dysfunction. [2]
Injuries at the level of T1 to T8 result in inability to control the abdominal muscles. Trunk stability may be affected; even more so in higher level injuries. [48] The lower the level of injury, the less extensive its effects. Injuries from T9 to T12 result in partial loss of trunk and abdominal muscle control. Thoracic spinal injuries result ...
Denervation can occur as a consequence of nerve injury. The three primary categories of nerve injury are neurapraxia, axonotmesis, and neurotmesis, each corresponding to varying degrees of damage and potential for recovery. In cases of nerve injury, the brain demonstrates an impressive ability to rewire or reorganize its neuronal circuitry ...
Disuse atrophy of the muscle occurs i.e., shrinkage of muscle fibre finally replaced by fibrous tissue (fibrous muscle) Other causes include Guillain–Barré syndrome, West Nile fever, C. botulism, polio, and cauda equina syndrome; another common cause of lower motor neuron degeneration is amyotrophic lateral sclerosis.
The exoskeleton may be used in areas that can not afford robotic devices, or, in areas that can not provide adequate physiotherapy care. Restorative neurology offers a different paradigm of treating spinal cord injury by focusing on the residual remaining motor control and on the intrinsic function of the sub-lesional spinal cord segments.

Spinal muscular atrophy (SMA) is a rare neuromuscular disorder that results in the loss of motor neurons and progressive muscle wasting. [ 3 ] [ 4 ] [ 5 ] It is usually diagnosed in infancy or early childhood and if left untreated it is the most common genetic cause of infant death. [ 6 ]
