髌股疼痛综合征(PFPS)是一组对个体日常生活活动产生负面影响的症状,导致功能性残疾和大量劳动力损失,尤其是年轻人。PFPS通常是由于股内侧斜肌(VMO)的虚弱导致the骨跟踪异常和疼痛。我们的研究旨在比较高强度激光治疗(HILT)对不同电物理药物(EPA)治疗PFPS的疼痛和下肢功能的疗效。该研究设计为单盲随机对照试验。45名PFPS患者(25-45岁)被纳入研究。将患者随机分为3组,共治疗10次,疗程2周,一周五天。第1组采用高强度激光(HILT)和运动程序。超声(美国),经皮神经电刺激(TENS),并将锻炼计划应用于第2组。在第3组,美国,干扰电流(IFC),并应用了锻炼计划。两组都进行了三项评估:治疗前,治疗后,治疗后12周。结果测量包括疼痛严重程度的视觉模拟量表(VAS),膝关节屈曲运动范围(FROM),Q角,痛阈值,股四头肌和腿筋的肌肉力量,Kujala髌股评分,下肢功能量表(LEFS),和定时和去测试(TUG)。方差分析用于比较各组数据,在干预前和干预后第3个月使用双向重复测量ANOVA进行比较.LSD和Bonferroni事后检验也用于鉴定组间差异。第2组和第3组在疼痛和功能方面具有统计学上的有效性(p<0.05)。发现第1组在减轻疼痛方面比其他组在统计学上更有效(95%置信区间(CI),0.000/0.000;p=0.000),增加膝关节屈曲角度(95%CI,127.524/135.809;p=0.000),增加下肢功能(95%CI,75.970/79.362;p=0.000)。这项研究表明,与US-TENS组合和US-干扰目前的联合治疗相比,高强度激光治疗在随访3个月后被发现是治疗髌股疼痛综合征的更有效方法。此外,HILT可作为一种有效的方法,与适当的运动计划相结合,包括加强股内侧肌,以减轻PFPS患者的疼痛并增加功能。
Patellofemoral pain syndrome (PFPS) is a set of symptoms that negatively affect the daily life activities of the individual, leading to functional disability and significant loss of labor, especially in young adults. PFPS is usually due to weakness of the vastus medialis obliquus (VMO) resulting in abnormal patellar tracking and pain. Our
study aims to compare the efficacy of high-intensity laser therapy (HILT) on pain and lower extremity function in the treatment of PFPS with different electrophysical agents (EPAs). The
study was designed as a single-blind randomized controlled
trial. Forty-five people with PFPS (aged 25-45 years) were included in the
study. The patients were randomly divided into three groups and a total of ten sessions of treatment were administered to all three groups for 2 weeks, 5 days a week. High-intensity laser (HILT) and exercise program were applied to group 1. Ultrasound (US), transcutaneous electrical nerve stimulation (TENS), and exercise program were applied to group 2. In group 3, US, interferential current (IFC), and exercise program were applied. Both groups underwent three evaluations: pre-treatment, post-treatment, and 12 weeks after treatment. Outcome measures included the visual analog scale for pain severity (VAS), knee flexion range of motion (FROM), Q angle, pain threshold, muscle strength of quadriceps and hamstring, Kujala patellofemoral scoring, lower extremity functional scale (LEFS), and Timed Up and Go Test (TUG). The ANOVA was used for comparing the data of the groups, and two-way repeated measure ANOVA was used to compare at the pre-post and post-intervention 3rd month. The LSD and Bonferroni post hoc tests were also used to identify the between-group differences. Groups 2 and 3 were statistically effective in pain and functionality (p < 0.05). Group 1 was found to be statistically more effective than other groups in reducing pain (95% confidence interval (CI), 0.000/0.000; p = 0.000), increasing knee flexion angle (95% CI, 127.524/135.809; p = 0.000), and increasing lower extremity function (95% CI, 75.970/79.362; p = 0.000). This
study indicated that high-intensity laser therapy was found to be a more effective method in the treatment of patellofemoral pain syndrome after 3 months of follow-up compared to US-TENS combination and US-interferential current combination treatments. Also, HILT can be used as an effective method in combination with an appropriate exercise program including vastus medialis strengthening to reduce pain and increase functionality in the patients with PFPS.
