A detailed study of the patterns of two movements (pure metacarpophalangeal flexion and pure interphalangeal extension) in intrinsic minus fingers shows that the long extensors and long flexors produce simultaneous movement at the metacarpophalangeal and interphalangeal joints. A comparison of the patterns of these movements in totally intrinsic minus and interosseous minus fingers shows that in the latter the lumbricals are probably largely inactive during attempted pure metacarpophalangeal flexion and contribute to restrain metacarpophalangeal extension considerably during attempted pure interphalangeal extension. Active participation by the interosseous muscles appears necessary for completing these movements.
对内在肌功能减弱手指的两种运动模式（单纯掌指关节屈曲和单纯指间关节伸展）的详细研究表明，指长伸肌和指长屈肌在掌指关节和指间关节产生同步运动。对完全内在肌功能减弱和骨间肌功能减弱手指的这些运动模式进行比较后发现，在后者中，在尝试单纯掌指关节屈曲时，蚓状肌可能基本不活动，而在尝试单纯指间关节伸展时，蚓状肌在很大程度上有助于抑制掌指关节伸展。骨间肌的积极参与似乎是完成这些运动所必需的。
