Relevant muscle selection for needle electromyography examination in polio survivors

Objectives: Needle electromyography (EMG) has an important role in the diagnosis of poliomyelitis. Since needle EMG is a painful and time consuming procedure, selecting most effective muscles for important. We aimed to determine clinically or subclinically affected regions polio survivors by examining minimum number with EMG. Methods: Polio weakness at least one limb were included this retrospective cohort study. The extremities divided into two groups: 1) Group 1: Medical Research Council score ≤ 1 muscle, 2) 2: Clinically unaffected mildly moderately that do not meet criteria 1. findings analyzed. Results: Twenty-nine 352 reviewed. 57 lower thirty-two upper There was no extremity meeting Thirty-eight amplitudes durations motor unit action potentials (MUAPs) different between (p > 0.05). Among 2 extremities, amplitude duration MUAPs higher deltoid vastus lateralis compared other muscles, respectively = 0.002 p 0.003 muscles; 0.005 < 0.001 muscles). Conclusions: Using findings, algorithm made regions. Thus, can be identified applying muscles.
