Electromyography can demonstrate fibrillation potentials and positive sharp waves in the more distal weak limb muscles along with decreased recruitment of polyphasic, long-duration, large-amplitude MUAPs.
They do not correspond to the SENIAM recommendations which focuses merely on amplitude and frequency characteristics, timing properties and MUAP width and shape [20].
EMG reveals fibrillation potentials, positive sharp waves, and early recruitment of myopathic MUAP in proximal muscles.
Right median, ulnar and radial nerve innervating the distal muscles had neurogenic motor unit action potential (MUAP) changes with fewer MUAPs.
Analyzing the MUAPs can also be used to gauge the duration and progression of LSS.
