Résumé
A 21-year-old Thai man presented with progressive weakness and atrophy of both hands for 2 years. His left leg was atrophic and weak secondary to poliomyelitis since he was 8 months old. Physical examination showed that there was atrophy of both hands and forearms as well as left leg. Sensation was normal. Deep tendon reflexes were normal except for hyporeflexia of left leg. EMG showed chronic denervation pattern in the recent atrophic muscles and in normal power muscles. Motor and sensory nerve conductions were normal. Biopsy of forearm muscle revealed degeneration and fibrosis of muscle fibers. These findings were compatible with post-polio syndrome (PPS) which presents in patients with late paralysis following poliomyelitis. It is not a form of amyotrophic lateral sclerosis although some clinical similarities exist. Weakness from PPS may lead to musculoskeletal pain and increased functional disability. Proper rehabilitation program is to maintain his functional status and allow him to continue to live as independently as possible by regular exercise without stressing joints and muscles.
