Faulty lower limb mechanics and increased of knee valgus on loaded tasks are believed to play an important role in the development of PFP. Objective: To figure out if male PFP patients during single leg horizontal hop for distance and squat with greater knee valgus than controls, and if the nature of the task changes the angles of knee valgus. Methods: Twenty males with unilateral PFP formed the patient group and forty-five asymptomatic males formed the control group. Two dimensional (2-D) frontal plane projection angle (FPPA) was used during single leg squatting and horizontal hop for distance tasks. Results: For the single leg squat, the mean of 6.96<span style="white-space:nowrap;">°</span>, 9.80<span style="white-space:nowrap;">°</span>, 15.04<span style="white-space:nowrap;">°</span> was reported in the control, PFP asymptomatic knee, and PFP symptomatic knee, respectively. For the single leg horizontal hop for distance, the mean of 11.63<span style="white-space:nowrap;">°</span>, 13.72<span style="white-space:nowrap;">°</span>, 19.17<span style="white-space:nowrap;">°</span> was reported in the control, PFP asymptomatic knee, and PFP symptomatic knee, respectively. These differences were significant (<em>p </em>< 0.002) for both tasks. Conclusions: Patients with PFP represented with greater knee valgus angle than what was found in either their asymptomatic limb or in the control group.展开更多

文摘目的:观察针刺股四头肌激痛点结合静态拉伸股四头肌治疗髌股疼痛综合征的临床疗效。方法:50例髌股疼痛综合征(patellofemoral pain syndrome,PFPS)病人,随机分为两组(n=25):实验组采用针刺股四头肌激痛点结合股四头肌拉伸。对照组采用安慰剂针法,拉伸和实验组相同,两组均每周针刺1次,拉伸每日3次,每次1 min,持续6周。于治疗前、治疗3周和6周后和治疗结束后3个月,分别采用疼痛数字评价量表(numberical rating scale,NRS)、膝关节主动屈膝活动度(active range of motion,AROM)和膝关节Lysholm评分进行疗效观察。结果:两组病人一般资料无显著性差异,两组NRS在治疗3周、6周后,较治疗前均有显著性下降,但3个月随访时,对照组较治疗前无显著性差异;两组治疗后的膝关节AROM较治疗前均有显著性提高,但是在治疗6周后,实验组显著高于对照组;两组膝关节Lysholm评分治疗后较治疗前均有显著性提高,但是在治疗6周后和3个月随访,实验组显著高于对照组。结论:针刺激痛点与安慰针疗法结合静态拉伸均可在短期内有效缓解疼痛及改善膝关节活动度,但前者长期效果更佳。
