目的:为了研究高频强化程序对功能的影响,疼痛,慢性髌股疼痛(PFP)的女性跑步者的疼痛敏感性。
方法:横断面研究。
方法:大学实验室。
方法:30名患有慢性PFP的女性跑步者(平均年龄32±8.1岁)完成了为期8周的家庭强化计划。
方法:基线评估的变量,8周,12周包括单腿降压测试(SLSD),疼痛,膝关节前疼痛量表(AKPS),威斯康星大学跑步伤害和恢复指数(UWRI)和定量感官测试。
结果:平均膝关节疼痛在8周和12周时有较大且统计学上显著的改善(ηp2=0.334,p<0.001),最严重的膝关节疼痛(ηp2=0.351,p<0.001),SLSD(ηp2=0.161,p=0.001),AKPS(ηp2=0.463,p<0.001),和UWRI(ηp2=0.366,p<0.001)。对于所有本地和远程结构(ηp2范围,0.110至0.293,范围p<0.001至p=0.009)在8周和12周。
结论:通过机械和热痛敏感性测试,患有慢性PFP的女性跑步者的局部和远程痛觉过敏显着降低。自我报告的疼痛和功能有很大的效果和显着改善。
OBJECTIVE: To investigate the effects of a high frequency strengthening program on function, pain, and pain sensitization in female runners with chronic patellofemoral pain (PFP).
METHODS: Cross-sectional study.
METHODS: University laboratory.
METHODS: Thirty female runners (mean age 32 ± 8.1 years) with chronic PFP completed an 8-week home strengthening program.
METHODS: Variables assessed at baseline, 8-weeks, and 12 weeks included single leg step down test (SLSD), pain, Anterior Knee Pain Scale (AKPS), University of Wisconsin Running Injury and Recovery Index (UWRI), and quantitative sensory testing.
RESULTS: There was large and statistically significant improvement at 8 and 12 weeks for average knee pain (ηp2 = 0.334, p < 0.001), worst knee pain (ηp2 = 0.351, p < 0.001), SLSD (ηp2 = 0.161, p = 0.001), AKPS (ηp2 = 0.463, p < 0.001), and UWRI (ηp2 = 0.366, p < 0.001). A medium to large effect and statistically significant improvement in pressure pain threshold testing was found for all local and remote structures (ηp2 range, 0.110 to 0.293, range p < 0.001 to p = 0.009) at 8 and 12 weeks.
CONCLUSIONS: There was a significant decrease in local and remote hyperalgesia via mechanical and thermal pain sensitivity testing in female runners with chronic PFP. There was a large effect and significant improvement in self-reported pain and function.
