Metal markers were used to study flexor digitorum profundus tendon excursions during early controlled motion with a new program combining dynamic traction and passive flexion to all four digits. The mean excursion was 2.3 mm along the middle phalanx and 11.7 mm along the proximal phalanx. This was more than twice the mean size of excursions previously achieved with a modified traditional Kleinert traction program. The mean excursion per 10 degrees of combined distal and proximal interphalangeal controlled joint motion amounted to 73% of the corresponding excursion recorded during active motion. Taken together with the findings of our previous study on tendon excursions, the results also indicate that the magnitude of excursions induced by both the distal and the proximal interphalangeal joints during controlled motion has a significant effect on adhesion formation and clinical results. However, in the region of 6 to 9 mm there appears to be a threshold beyond which the effect of a further increase in excursions becomes insignificant.
使用金属标记物，通过一个新的程序来研究早期控制运动期间指深屈肌腱的移动情况，该程序结合了对所有四个手指的动态牵引和被动屈曲。沿着中节指骨的平均移动距离为2.3毫米，沿着近节指骨的平均移动距离为11.7毫米。这比之前采用改良传统克莱纳特牵引程序所达到的平均移动距离的两倍还要多。每10度远侧和近侧指间关节控制的联合关节运动的平均移动距离相当于主动运动期间记录的相应移动距离的73%。结合我们之前关于肌腱移动的研究结果，这些结果还表明，在控制运动期间，远侧和近侧指间关节引起的移动幅度对粘连形成和临床结果有显著影响。然而，在6至9毫米的范围内似乎存在一个阈值，超过该阈值后，移动幅度进一步增加的影响变得微不足道。
