Physical therapy has been shown to be useful in decreasing pain and increasing mobility in this population. The aim of this study was to study the effectiveness of slow reversal hold and isometric exercise techniques in reducing pain, increasing muscle strength, and increasing range of motion for knee flexion in patients with osteoarthritis of knee. The other aim of this study was to compare the relative effectiveness of these two interventions. 60 subjects participated in this study and were randomly assigned either to the slow reversal hold group (n = 30) or, to the isometrics exercise group (n = 30). All subjects performed their respective exercises for 3 weeks. Pain scores using the visual analog scale, muscle strength using manual muscle testing of quadriceps and hamstrings, and range of motion (ROM) for knee flexion using a goniometer were recorded both pre-treatment and post-treatment for both left and right knees. Both the interventions showed a significant decrease in pain scores, an increase in muscle strength, as well as an increase in the ROM. However, ROM was significantly increased in the slow reversal hold group as compared to the isometrics group in both knees. It was concluded that both exercise techniques could be useful in patients with osteoarthritis of knee for decreasing pain and increasing muscle strength. Slow reversal hold technique might be a better technique than isometrics for increasing ROM for knee flexion.展开更多
目的评价膝关节骨关节炎(OA)患者患侧及健侧膝伸肌和屈肌在等长、等速向心和等速离心收缩时的功能特性及相互间的关系。方法应用Biodex system 3型等速测试系统对54例单侧膝OA患者进行患侧和健侧膝伸肌和屈肌的等长、等速向心及等速离...目的评价膝关节骨关节炎(OA)患者患侧及健侧膝伸肌和屈肌在等长、等速向心和等速离心收缩时的功能特性及相互间的关系。方法应用Biodex system 3型等速测试系统对54例单侧膝OA患者进行患侧和健侧膝伸肌和屈肌的等长、等速向心及等速离心肌力测试。结果膝OA患者患侧膝关节伸肌和屈肌在不同收缩模式下的肌力均较健侧显著下降(P＜0．05),特别是在低速向心和低速离心收缩状态时的降低幅度尤为显著；同时患者的膝关节屈/伸肌肌力(H/Q)比值和动态控制率均提示其患侧肢体存在肌力平衡异常。结论在对膝OA患者肌肉功能进行评定时,应选用等速肌力测试并同时分析其H/Q比值及动态控制率,只有这样才能对患者的肌肉状况作出全面而客观的评定。展开更多

文摘目的观察中药穴位注射疗法对早中期膝关节骨性关节炎患者Western Ontario大学和McMaster大学关节炎量表(WOMAC)评分及膝关节屈伸肌力的影响。方法将2015年7月至2017年12月该科收治的80例患者按照随机数字表法分为中药穴位注射组和玻璃酸钠组,每组40例。中药穴位注射组采用膝关节穴位注射舒血宁注射液治疗,玻璃酸钠组采用关节腔注射玻璃酸钠治疗,每组均每周注射1次,5次为1个疗程,同时使用BIODEX System 4等速肌力测试系统测试等速向心/向心模式下的患膝关节屈、伸肌力矩峰值。观察2组治疗前后的WOMAC评分及膝关节屈、伸肌力矩峰值的变化情况。结果 2组治疗疗效比较,差异无统计学意义(P>0.05);2组治疗后的WOMAC评分均较同组治疗前下降,且中药穴位注射组治疗后WOMAC评分较玻璃酸钠组低,差异均有统计学意义(P<0.05);2组治疗后膝关节伸肌力矩峰值较治疗前明显上升,差异均有统计学意义(P<0.05);相同角速度下,中药穴位注射组治疗后伸肌力矩峰值较玻璃酸钠组高,但差异均无统计学意义(P>0.05);在低速角速度(60°/s)下,2组治疗后膝关节屈肌力矩峰值与治疗前比较,差异均有统计学意义(P<0.05);在高速角速度(180°/s)下,2组治疗后膝关节屈肌力矩峰值较治疗前轻微上升,但差异均无统计学意义(P>0.05)。结论中药穴位注射疗法治疗早中期膝关节骨性关节炎的疗效确切,可以减轻疼痛,改善膝关节功能,提高膝关节伸肌肌力,是一种治疗早中期膝关节骨性关节炎的有效方法。
文摘目的评价膝关节骨关节炎(OA)患者患侧及健侧膝伸肌和屈肌在等长、等速向心和等速离心收缩时的功能特性及相互间的关系。方法应用Biodex system 3型等速测试系统对54例单侧膝OA患者进行患侧和健侧膝伸肌和屈肌的等长、等速向心及等速离心肌力测试。结果膝OA患者患侧膝关节伸肌和屈肌在不同收缩模式下的肌力均较健侧显著下降(P＜0．05),特别是在低速向心和低速离心收缩状态时的降低幅度尤为显著；同时患者的膝关节屈/伸肌肌力(H/Q)比值和动态控制率均提示其患侧肢体存在肌力平衡异常。结论在对膝OA患者肌肉功能进行评定时,应选用等速肌力测试并同时分析其H/Q比值及动态控制率,只有这样才能对患者的肌肉状况作出全面而客观的评定。
