背侧骨间肌、掌侧骨间肌和蚓状肌的动作使用施加的电刺激进行研究，并记录在掌指关节屈曲/伸展和外展/内收、近端指间关节屈曲/伸展和远端指间关节屈曲/伸展时产生的力矩。这些测量是在各种关节角度和刺激水平下对健全受试者和持续性四肢瘫痪的人进行的。确定背侧骨间肌（包括第一骨间肌）是手指的强外展肌，并在掌指（MP）关节屈曲和指间（IP）关节伸展中产生显著力矩。掌侧骨间肌是手指的主要内收肌，并在MP关节屈曲和IP关节伸展中提供重要力矩。蚓状肌被认为是MP关节屈肌和IP关节伸肌，尽管产生的力矩平均比骨间肌低70%。从数据中无法确定蚓状神经作为手指外展肌或内收肌的作用。这些关于内在肌肉的动作和力矩产生能力的信息导致骨间肌并入由植入的神经假体提供的电诱导手抓握中。通过记录这些肌肉在手指的每个关节上的力矩产生能力来完成神经假体中的内在肌肉的评估。这些肌肉能够产生的力矩是身体健全的受试者所获得的平均值的80-90%，并且为电诱导的手抓握提供了实质性的改善。
The actions of the dorsal interosseous, volar interosseous, and lumbrical muscles were investigated using applied electrical stimulation and recording the moments that were generated across the metacarpophalangeal joint in flexion/extension and abduction/adduction, the proximal interphalangeal joint in flexion/extension, and the distal interphalangeal joint in flexion/extension. These measurements were made isometrically at various joint angles and levels of stimulation with both able bodied subjects and persons who had sustained tetraplegia. It was determined that the dorsal interossei, including the first, were strong abductors of the fingers and generated a significant moment in metacarpophalangeal (MP) joint flexion and interphalangeal (IP) joint extension. The volar interossei were the primary adductors of the fingers, as well as providing a significant moment in MP joint flexion and IP joint extension. The lumbrical muscles were found to be MP joint flexors and IP joint extensors, although the moments that were generated were on average 70% lower than the interossei. The role of the lumbricals as finger abductors or adductors could not be determined from the data. This information on the actions and moment generating capabilities of the intrinsic muscles led to the incorporation of the interossei into electrically induced hand grasp provided by an implanted neuroprosthesis. The evaluation of the intrinsic muscles in the neuroprosthesis was accomplished by recording the moment generating capabilities of these muscles across each of the joints of the finger. These muscles were capable of generating moments that were 80-90% of the average attained by the able bodied subjects, and have provided a substantial improvement to the electrically induced hand grasp.
