Abstract:Objective To investigate the clinical and electrophysiological features of post-poliomyelitis syndrome (PPS), and to investigate diagnosis, differential diagnosis, and treatment.Methods The clinical data of 10 patients with PPS were analyzed retrospectively.Results All the 10 patients had weakened muscle strength in the affected limbs; 5 patients were accompanied by fatigue, 3 patients by intolerable chill, and 5 patients by pain in limbs. The typical electrophysiological features included prolonged duration, increased amplitude, and reduced recruitment order of motor unit potential, as well as normal motor and sensory nerve conduction.Objective The most common symptoms of PPS are weakness, chronic fatigue, and pain, and its diagnosis is mainly based on a comprehensive analysis of medical history, clinical manifestations, and electrophysiological features. The treatment of PPS includes rehabilitation and medication, and early intervention can improve quality of life.
