背景和目的。跟腱延长术（TAL）对踝关节肌肉性能的影响尚未明确。本研究的目的是比较TAL和全接触铸造（TCC）与TCC单独对糖尿病（DM）和神经性足底溃疡受试者踝关节肌肉性能的影响。科目受试者被随机分配至TAL组（3名女性和12名男性受试者）或TCC组（4名女性和10名男性受试者）。方法.肌肉性能测量使用等速测力计。结果TAL后，同心跖屈肌峰值扭矩下降31%，但在8个月后恢复到基线水平。两组背屈肌峰值扭矩均未发生变化。TAL后0度背屈时的跖屈肌被动扭矩降低，但8个月后增加至基线水平的60%。TAL后最大背屈角增加11度，并在8个月时保持增加。讨论和结论。TAL导致踝关节背屈运动范围增加，6度背屈时向心跖屈肌峰值扭矩和被动扭矩暂时降低。如果TAL被认为是糖尿病和神经性前足溃疡的人，在跖屈肌性能的初步妥协应加以解决。[Salsich GB，Mueller MJ，Hastings MK，et al.

Background and Purpose. The effect of a tendo-Achilles lengthening (TAL) procedure on ankle muscle performance has not been clearly established. The purpose of this study was to compare the effects of TAL and total-contact casting (TCC) with TCC alone on ankle muscle performance in subjects with diabetes mellitus (DM) and a neuropathic plantar ulcer. Subjects. Subjects were randomly assigned to either a TAL group (3 female and 12 male subjects) or a TCC group (4 female and 10 male subjects). Methods. Muscle performance measurements were obtained using an isokinetic dynamometer. Results. Concentric plantar-flexor peak torque decreased 31% after TAL but returned to the baseline level after 8 months. Dorsiflexor peak torque did not change in either group. Plantar-flexor passive torque at 0 degrees of dorsiflexion decreased after TAL but increased to 60% of the baseline level after 8 months. Maximal dorsiflexion angle increased I I degrees after TAL and remained increased at 8 months. Discussion and Conclusion. The TAL resulted in an increase in ankle dorsiflexion range of motion and a temporary reduction in concentric plantar-flexor peak torque and passive torque at 6 degrees of dorsiflexion. If TAL is being considered for people with DM and a neuropathic forefoot ulcer, the initial compromise in plantar-flexor muscle performance should be addressed.
