Outcome assessment
Fasciculations, pain
CONTRACTION, FLICKER
Motor and sensory functions were evaluated according to the British Medical Research Council (BMRC) scale. Excellent: Complete recovery of muscle strength on the affected side and complete recovery of superficial pain and tactile sensation. Good: Incomplete recovery of muscle strength on the affected side and incomplete recovery of superficial pain and tactile sensation. Muscle contraction can still move joint against week resistance. Fair: Incomplete recovery of muscle strength on the affected side. Partial recovery of superficial pain and tactile sensation. Muscle strength is further reduced. Poor: No recovery of muscle strength on the affected side and superficial pain and tactile sensation.The strength of muscle was assessed by the Lovett scale. V: Muscle contracts normally against full resistance. IV: Muscle strength is reduced but muscle contraction can still move joint against resistance. III: Muscle strength is further reduced such that the joint can be moved only against gravity with the examiner's resistance completely removed. II: Muscle can move only if the resistance of gravity is removed. I: Fasciculations are observed in the muscle or only a trace or flicker of movement is seen or felt in the muscle.Key pinch strength was evaluated by pinch gauge (B&L Engineering, Santa Ana, California). Grip strength was evaluated by Jamar dynamometer (Sammons Preston Rolyan, Bolingbrook, Illinois).
