本研究提出的方法，以确定关节力矩的手的手指在捏功能。该方法包含了识别基于标记的运动学数据的步骤，这些数据定义了单个数字段和关节中心位置的对齐坐标系。然后将运动学数据与定制设备在三维（3-D）捏触时收集的力数据一起转换为公共参考系。这些方法通过试点调查来验证，以检查在特定端点力水平施加于手指垫的两位数对位精确捏捏期间发生的静态关节力矩。在两指近端关节处观察到明显的外展关节力矩，这暗示了各自的内在和外在肌肉在维持抓握中的作用。当替换此方法学方法的选择步骤时，检查关节力矩结果的差异表明，对于关节中心识别和段坐标系对齐具有更大的相对重要性。
This study presents methodology to determine joint moments of the digits of the hand during pinch function. This methodology incorporates steps to identify marker-based kinematic data defining aligned coordinate systems for individual digit segments and joint center locations. The kinematic data are then transformed to a common reference frame along with the force data collected at pinch contact of a customized apparatus in three-dimensions (3-D). These methods were demonstrated with a pilot investigation to examine the static joint moments occurring during two-digit oppositional precision pinch at a particular endpoint force level applied at the digit pads. Notable abduction joint moments at the proximal joints of both digits were observed, which implicate the role of respective intrinsic and extrinsic muscles in maintaining pinch grasp. Examining differences in joint moment results when substituting select steps of this methodological approach suggested greater relative importance for joint center identification and segment coordinate system alignment.
