Multichannel Nerve Stimulation for Diverse Activation of Finger Flexors

Objective: Neuromuscular electrical stimulation (NMES) is a common approach to restore muscle strength of individuals with a neurological injury but restoring hand dexterity is still a challenge. This study sought to quantify the diversity of finger movements elicited by a multichannel nerve stimulation technique. Methods: A 2 × 8 stimulation grid, placed on the upper arm along the ulnar and median nerves, was used to activate different finger...
