The purpose of this study was to compare the effect of unrestricted active versus passive mobilization on the gliding function and structural properties (ultimate load and stiffness) of repaired and nonrepaired canine flexor digitorum profundus tendons following partial laceration at 1 week. Using a radiographic method, normalized tendon gliding of the flexor digitorum profundus tendon adjacent to the metacarpal bone and total joint rotation were shown to be significantly greater in passive than in active tendons. Each group differed from their control group, however, by an average of only 5%. Both rehabilitation (active vs. passive) and treatment (repair vs. nonrepaired) of the partial tendon laceration significantly affected gap formation. Both active rehabilitation and repair of the laceration significantly increased gap formation compared with passive rehabilitation and nonrepair of the partial laceration. Rehabilitation did not significantly affect the normalized ultimate loads and stiffness in the passive and active groups but the nonrepair groups displayed significantly higher ultimate loads and stiffness than the repair groups.
本研究的目的是比较在第1周部分撕裂后，无限制主动活动与被动活动对修复和未修复的犬指深屈肌腱滑动功能及结构特性（极限负荷和刚度）的影响。采用放射照相法显示，与掌骨相邻的指深屈肌腱的标准化肌腱滑动以及总关节旋转在被动肌腱中显著大于主动肌腱。然而，每组与各自的对照组相比，平均仅相差5%。部分肌腱撕裂的康复（主动与被动）和治疗（修复与未修复）均显著影响间隙形成。与被动康复和部分撕裂未修复相比，主动康复和撕裂修复均显著增加了间隙形成。康复对被动组和主动组的标准化极限负荷和刚度没有显著影响，但未修复组的极限负荷和刚度显著高于修复组。
