Two experimental studies were conducted to investigate flexor tendon excursions. In the first study, tendon excursions due to passive joint motion in various loading condition were evaluated. In the second study, the efficacy of a new technique that used synergistic wrist motion (S-splint) was compared with the traditional dorsal splinting methods: the Kleinert splint (K-splint) and the Brooke Army Hospital/Walter Reed modified Kleinert splint with a palmar bar (P-splint). The results of these studies question the anticipated tendon excursion associated with postoperative splinting. They demonstrated that the measured tendon excursion under a condition of low tendon tension was almost half that of theoretically predicted values. In zone II, the magnitude of excursion introduced by the three mobilization methods were in descending order: S-splint, P-splint, K-splint (p less than 0.05). Differential tendon excursion between the flexor digitorum profundus and the flexor digitorum superficialis had a mean value of 3 mm and was not significantly different among the three methods. Passive proximal interphalangeal joint motion was the most effective means of providing increased amplitude of tendon gliding in zone II. Passive distal interphalangeal joint motion did not increase excursion in zone II as much as had been predicted.
进行了两项实验研究以调查屈肌腱的移动情况。在第一项研究中,评估了在各种负荷条件下被动关节运动引起的肌腱移动。在第二项研究中,将一种使用协同腕部运动的新技术(S型夹板)的效果与传统的背侧夹板方法进行了比较:克莱纳特夹板(K型夹板)和带有掌侧杆的布鲁克陆军医院/沃尔特·里德改良克莱纳特夹板(P型夹板)。这些研究结果对术后夹板固定相关的预期肌腱移动提出了质疑。研究表明,在低肌腱张力条件下测量的肌腱移动几乎是理论预测值的一半。在II区,三种活动方法引起的移动幅度由大到小依次为:S型夹板、P型夹板、K型夹板(p<0.05)。指深屈肌和指浅屈肌之间的差异肌腱移动平均值为3毫米,三种方法之间无显著差异。被动近端指间关节运动是增加II区肌腱滑动幅度的最有效方法。被动远端指间关节运动在II区增加的移动幅度没有达到预期的程度。
