Brief Summary

Does movement of hand from supination to pronation affect the cut threshold for electomyography (EMG) relaxation measurement Does the threshold level differ between adductor pollucis and dorsal interosseus muscle

Conditions

Relaxation

Keywords

Train of four; EMG

Outcome Measures

Primary Outcomes (2)

• To differ the difference in the stimulation current between adductor pollucis and dorsal interosseus muscles

  Defining the supramaximal stimulation current in the hand using EMG muscle rekaxation

  30 minutes

• To differ the stimulation threshold in hand supination and pronation postures

  Measuring the EMG stimulation threshold in two hand postures

  30 minutes
