本研究的目的是：1）评估踝关节在30、90和240 °时的跖屈和背屈峰值扭矩（PT）。101例患者中的s-1（86名男性，15名女性），他们在1987-1992年期间在芬兰欧卢的欧卢大学医院因单侧完全闭合性跟腱（AT）断裂接受手术，2）确定双腿之间的比较是否显示任何损伤，3）研究无力是否与速度相关，（4）确定踝关节在什么角度位移时表现出无力;（5）研究结果与年龄、手术类型和随访时间的关系。Lido Multi-joint II测力计用于测量。双腿之间比较时，没有检测到明显的背屈无力，但在30、90和240度时，受伤肢体的平均相对峰值扭矩赤字分别为8.4%、9.0%和3.0%。男子分别为15.0%、16.6%和6.4%。在所有测试速度下，女性的平均百分比扭矩差异显著更大（p < 0.05）。在两个低测试速度（30和90）下，PT的差异显著更大。s-1）比在高速（240.. s-1，p < 0.001）。无力表现在80-120度的角位移，其中两条腿之间的平均峰值功（PW）差异在两种性别中均显著（p < 0.05）。患者年龄（21-63岁）、手术类型（Lindholm或Silfverskiöld技术）和随访时间（0.7-6.7年）对结果无显著影响。总之，AT断裂意味着平均3.0%至16.6%的等速跖屈肌肉力量受损。女性的损伤更大，表现在80-120度的角位移，并且在低测试速度下更大。年龄、手术类型和随访时间不能解释患者之间的PT差异。
The purposes of this study was 1) to assess the plantar flexion and dorsiflexion peak torques (PT) of the ankles at 30, 90 and 240.. s-1 in 101 patients (86 men, 15 women) who had been operated on for unilateral, complete closed Achilles tendon (AT) rupture at Oulu University Hospital, Oulu, Finland, in the period 1987-1992, 2) to determine whether comparison between the legs shows any impairment, 3) to study whether the weakness is speed-dependent, 4) to determine at what angular displacement of the ankle the weakness is manifested, 5) to study how the results correlate with age, type of operation and follow-up time. The Lido Multi-joint II dynamometer was used for the measurements. There was no significant dorsiflexion weakness detectable upon comparison between the legs, but the mean relative peak torque deficits in the injured limb were 8.4, 9.0 and 3.0% at 30, 90 and 240.. s-1 respectively for the men and 15.0, 16.6 and 6.4% for the women. The mean percentage torque differences were significantly greater in the women at all the test speeds (p < 0.05). The difference in PT was significantly greater at the two low test speeds (30 and 90.. s-1) than at the high speed (240.. s-1, p < 0.001). The weakness was manifested at an angular displacement of 80-120 degrees, where the average peak work (PW) difference between the two legs was significant in both sexes (p < 0.05). The patient's age (21-63), the type of operation (Lindholm or Silfverskiöld technique) and the follow-up time (0.7-6.7 years) did not significantly affect the results. In conclusion, and AT rupture implied an average 3.0 to 16.6% impairment in isokinetic plantar flexion muscle strength. The impairment was greater in the women, was manifested at an angular displacement of 80-120 degrees, and was greater at low test speeds. Age, type of operation and follow-up time did not account for the PT differences between the patients.
