This study evaluated the effects of unmodified prefabricated foot orthoses over a 12-week period on functional performance; and subjective pain and function in individuals with patellofemoral pain syndrome (PFPS).
Prospective cohort study over 12 weeks. Each participant was prescribed prefabricated foot orthoses at baseline.
Sixty individuals with PFPS (18-35 years).
Change in pain and ease of completing a single leg squat; change in the number of pain free step downs and single leg rises from sitting; usual and worst pain in the previous week; the anterior knee pain scale (AKPS); and the lower extremity functional scale (LEFS).
At 12 weeks, significant improvements in single leg squat pain and ease, and the number of pain free step downs and single leg rises from sitting were found. Additionally, significant reductions in usual and worst pain, and improvements on the AKPS and LEFS were observed.
Functional performance improvements following unmodified prefabricated foot orthoses were greater at 12 weeks that those achieved immediately. Enhanced functional performance over time may have significant implications for osteoarthritis prevention in some individuals with PFPS. Improvements in subjective pain and function appear to plateau over time.
本研究评估了未经改良的预制足部矫形器在 12 周内对功能表现的影响；以及对髌股关节疼痛综合征（PFPS）患者的主观疼痛和功能的影响。
12 周的前瞻性队列研究。每位参与者在基线时都被开具了预制足部矫形器。
60 名 PFPS 患者（18-35 岁）。
单腿深蹲疼痛和轻松程度的变化；从坐姿无痛单腿下蹲和单腿站立次数的变化；前一周的日常和最痛疼痛；前膝痛量表（AKPS）；和下肢功能量表（LEFS）。
在 12 周时，单腿深蹲疼痛和轻松程度以及无痛单腿下蹲和单腿站立次数均有显著改善。此外，日常和最痛疼痛显著减轻，AKPS 和 LEFS 也有所改善。
未经改良的预制足部矫形器在 12 周内的功能表现改善程度大于即刻改善程度。随着时间的推移，功能表现的增强可能对某些 PFPS 患者的骨关节炎预防有重要意义。主观疼痛和功能的改善似乎随着时间的推移而趋于稳定。
