Muscle moment arms at the human knee and ankle were estimated from muscle length changes measured as a function of joint flexion angle in cadaver specimens. Nearly all lower-leg muscles were studied: extensor digitorum longus, extensor hallucis longus, flexor digitorum longus, flexor hallucis longus, gastrocnemius lateralis, gastrocnemius medialis, peroneus brevis, peroneus longus, peroneus tertius, plantaris, soleus, tibialis anterior, and tibialis posterior. Noise in measured muscle length was filtered by means of quintic splines. Moment arms of the mm. gastrocnemii appear to be much more dependent on joint flexion angles than was generally assumed by other investigators. Some consequences for earlier analyses are mentioned.
通过测量尸体标本中肌肉长度随关节屈曲角度的变化，估算了人体膝关节和踝关节处的肌肉力臂。几乎研究了所有小腿肌肉：趾长伸肌、拇长伸肌、趾长屈肌、拇长屈肌、外侧腓肠肌、内侧腓肠肌、短腓骨肌、长腓骨肌、第三腓骨肌、跖肌、比目鱼肌、胫骨前肌和胫骨后肌。测量的肌肉长度中的噪声通过五次样条进行滤波。腓肠肌的力臂似乎比其他研究者通常认为的更依赖于关节屈曲角度。文中提到了对早期分析的一些影响。
