S形力传感器被开发用于测量沿沿着肌腱的力。 校准后，传感器被施加到拇长屈肌和屈肌指浅和深肌腱的5例手术治疗腕管综合征的食指。 记录手腕和手指被动和主动运动过程中产生的肌腱力。 对于夹持功能，使用专用夹持计测量所施加的负载量。 肌腱的力量在0.1至0.6公斤力的范围内进行了测量，在被动活动的手腕。 肌腱力高达0.9公斤力的手指被动活动过程中存在。 肌腱的力量高达3.5公斤力，目前在积极的无阻力的手指运动。 在头端夹紧期间记录的肌腱力高达12.0 kgf，平均施加的夹紧力为3.5 kgf。 这些结果有潜在的应用，在确定的力量，肌腱修复将在被动和主动术后动员抵抗。
S-shaped force transducers were developed for measurement of the forces along intact tendons. After calibration, the transducers were applied to the flexor pollicis longus and flexor digitorum superficialis and profundus tendons of the index finger in five patients operated on for treatment of carpal tunnel syndrome. The tendon forces generated during passive and active motion of the wrist and fingers were recorded. For pinch function, the amount of the applied load was measured with a special pinch meter. Tendon forces in the range of 0.1 to 0.6 kgf were measured during passive mobilization of the wrist. Tendon forces up to 0.9 kgf were present during passive mobilization of the fingers. Tendon forces up to 3.5 kgf were present during active unresisted finger motion. Tendon forces up to 12.0 kgf were recorded during tip pinch, with a mean applied pinch force of 3.5 kgf. These results have potential application in determining the amount of force that a tendon repair would have to resist during passive as well as active postsurgical mobilizations.
