摘　　要：目的报道应用等速测力仪静态进展性牵伸治疗膝关节挛缩的方法及疗效。方法选取因骨折术后造成膝关节挛缩的患者16例,其中股骨干骨折2例,股骨远端骨折5例,髌骨骨折4例,胫骨平台骨折5例。术后平均病程13.7周。在等速测力计上实施静态进展性牵伸。每次关节活动在一个方向上牵伸,每次分5组牵伸,每组治疗时间5 min,组间休息1 min,下一组关节角度渐增。患者每日接受SPS治疗2次,每次治疗时间30 min,每周5 d,治疗疗程2月。分别在治疗前、治疗后、治疗后6月使用角度计测量伸膝角度E、屈膝角度F和关节活动度R。结果治疗后以及治疗后6个月,膝关节E、F、R 3个指标较治疗前均有明显改善(P<0.05)。结论应用等速测力仪静态进展性牵伸可以治疗膝关节挛缩。Objective To report the method used to treat knee joint contracture by static progressive stretch and evaluate its curative effect. Methods Sixteen patients with knee joint contracture after the orthopedic surgery were selected, including 2, femoral shaft fractures, 5 distal femur fracturs, 4 patellar fractures, 5 tibial plateau frac- tures. The average course of postoperative treatment was 13. 7 weeks. Static progressive stretch （SPS） was ap- plied by isokinetic dynamometer, with 5 sets of stretch in one direction for one treatment, each set lasts 5 minutes with 1 minute interval for rest, and the degree of joint position was increased progressively for the next set. Patients received SPS 2 times per day, 30 minutes per time, ,5 days per week, and the course of treatment lasted 2 months. The knee flexion degree （ F）, extension degree （E） and range of motion （R） were measured by goniometer before treatment, after treatment, 6 months after treatment, respectively. Results E, F and R of the knee joint were improved significantly both after treatment and 6 months after treatment as compared with those before treatment. Conclusions Application of isokinetic dynamometer by static progressive stretch can be used to treat knee joint contracture effectively.
