本报告描述了一种装置，该装置已被开发用于同时测量几个等轴测肘和肩力和力矩，并允许在水平面上的肩关节和肘关节角度范围内进行这种表征。该装置被用来表征由颈段脊髓损伤导致的四肢瘫痪的个体手肘伸展强度。在所有这些人中，自愿肘关节伸展完全由后三角肌提供，该肌肉先前已通过手术转移到瘫痪的三头肌肌腱。肘关节伸展对于许多日常活动是必不可少的，例如达到肩部以上的水平并将物体推离身体;广泛使用的后三角肌至三头肌肌腱转移手术在一定程度上恢复了对这一重要功能的自主控制。该装置包含一个六轴力-力矩传感器，每个受试者的手臂都连接在该传感器上。转换传感器的六个输出以对应于生理肘部和肩部力矩和力。定制表允许受试者的肩和肘角度在水平面内的宽范围内变化，以便可以在该平面内的受试者的可能功能范围内表征后三角肌长度的影响。研究发现，C5或C6四肢瘫痪受试者的肘关节伸展力量差异很大，从非常弱到足以推动手动轮椅。此外，大多数受试者手肘伸展力量表现出强烈的依赖于肘关节和肩关节的角度。当上臂被抬高到肩部水平时，肘部伸展通常较弱，不幸的是，这与这些人由于肩部无力而经常采用的位置相对应。
This report describes an apparatus which has been developed to measure several isometric elbow and shoulder forces and moments simultaneously and also allows this characterization to be performed across a range of shoulder and elbow joint angles in a horizontal plane. This apparatus was used to characterize the elbow extension strength in individuals with tetraplegia resulting from cervical level spinal cord injury. In all of these individuals, voluntary elbow extension was provided exclusively by the posterior deltoid muscle, which had previously been surgically transferred to the tendon of the paralyzed triceps muscle. Elbow extension is essential for many daily activities, such as reaching above shoulder level and pushing objects away from the body; the widely used posterior deltoid-to-triceps muscle tendon transfer surgery restores some degree of voluntary control to this important function. The apparatus contained a six-axis force-moment transducer to which the arm of each subject was attached. The six outputs of the transducer were transformed to correspond to physiological elbow and shoulder moments and forces. A customized table allowed the shoulder and elbow angles of the subject to be varied over a wide range in a horizontal plane so that the effects of posterior deltoid muscle length could be characterized over the likely functional range of the subject within this plane. It was found that elbow extension strength varied widely across subjects with C5 or C6 tetraplegia, from quite weak to strong enough to propel a manual wheelchair. Furthermore, the elbow extension strength of most subjects showed a strong dependence on both elbow and shoulder angles. Elbow extension was typically weak when the upper arm was elevated to shoulder level at the side, which unfortunately corresponds to the position often adopted by these individuals due to shoulder weakness.
