Botulinum toxin acts at neuromuscular junctions close to muscle motor points and is used to help manage spastic upper-limb deformities. To develop a system allowing clinicians to identify optimal injection sites by an easily reproducible technique, forearm flexor muscles were dissected in 20 formalin-preserved human limbs. Motor points for flexor carpi ulnaris, flexor carpi radialis, flexor digitorum superficialis and pronator teres were (1) identified, (2) related to a reference grid based on lines (proximal, distal, lateral, medial and diagonals) drawn between forearm anatomical landmarks, and (3) defined in terms of their percentage distances along the established grid lines.
肉毒杆菌毒素作用于靠近肌肉运动点的神经肌肉接头处，用于帮助处理上肢痉挛性畸形。为开发一种能让临床医生通过易于重复的技术识别最佳注射部位的系统，在20个用福尔马林保存的人体上肢中解剖了前臂屈肌。分别确定了尺侧腕屈肌、桡侧腕屈肌、指浅屈肌和旋前圆肌的运动点，（2）将其与基于在前臂解剖标志之间绘制的线（近端、远端、外侧、内侧和对角线）所构建的参考网格相关联，（3）并根据它们沿既定网格线的百分比距离进行定义。
