Muscle biopsy involves taking a muscle sample for examination with the aim to determine and confirm diagnosis of progressive spinal muscular atrophy. Electromyogram measures the muscle's electrical activity; abnormal electrical muscle activity caused by diseases and neuromuscular conditions can be distinguished by Electromyogram.


At present, there is still no specific treatment to heal damage to the nerve. Supportive care is managed with the help of physio and respiratory drainage.

Symptoms and Signs

Weakness and wasting of voluntary muscles is more severe in the legs compared to the arms. Because of the atrophied muscles in the parts closest to the body, there is great difficulty experienced in walking, crawling, swallowing. There is also difficulty in controlling the head and neck. Babies suffering for progressive spinal muscular atrophy will have trouble in lifting the head, delayed or lack in normal development in combination with problems in swallowing, breathing, and eating. Due to non-activity muscles are expected to shrink in size causing more difficulty.
