- Needle EMG of upper limb showed denervation potentials in the left biceps and bilateral first dorsal interosseous. Left upper limb showed neurogenic polyphasic MUAPs in all sampled muscles. Recruitment pattern was reduced with more reduction in distal muscles. Right side showed few polyphasic in extensor digitorum and first dorsal interosseous. Right deltoid was mostly unremarkable.
