BACKGROUND
The relationship between one-leg static standing balance (OLSSB) and patellofemoral pain syndrome (PFPS) is unknown.
HYPOTHESIS
OLSSB decreases in patients with PFPS.
DESIGN
Prospective case series.
METHODS
Fifty-two women with unilateral PFPS were enrolled in this study. OLSSB was evaluated with a stabilometer. Q angle was measured with a lengthened-arm universal goniometer. Lower extremity alignment was analyzed with full-length standing anteroposterior teleroentgenograms. Quadriceps and hamstring strength was measured on an isokinetic dynamometer.
RESULTS
There were significant differences in OLSSB, Q angle, and strength of quadriceps and hamstring between the symptomatic and asymptomatic sides. There was a correlation between the strength of the quadriceps and hamstring and OLSSB, while there was no correlation between OLSSB and the severity of pain, lower extremity alignment, and Q angle on the symptomatic side.
CONCLUSIONS
OLSSB and quadriceps and hamstring strength decreased and Q angle increased on the symptomatic side in PFPS patients. A relationship between OLSSB and pain, Q angle, and lower extremity alignment was not detected, while there was a correlation between the strength of the quadriceps and hamstring and OLSSB.
CLINICAL RELEVANCE
A quadriceps and hamstring strengthening may be beneficial to improve OLSSB in patients with PFPS.
背景
单腿静态站立平衡（OLSSB）与髌股关节疼痛综合征（PFPS）之间的关系尚不清楚。
假说
PFPS 患者的 OLSSB 降低。
设计
前瞻性病例系列。
方法
本研究纳入了 52 名单侧 PFPS 女性患者。使用平衡仪评估 OLSSB。使用加长臂通用量角器测量 Q 角。使用全长站立前后位 X 线片分析下肢对线。使用等速测力计测量股四头肌和腘绳肌力量。
结果
在症状侧和无症状侧，OLSSB、Q 角和股四头肌、腘绳肌力量存在显著差异。股四头肌和腘绳肌力量与 OLSSB 之间存在相关性，而 OLSSB 与症状侧疼痛严重程度、下肢对线和 Q 角之间无相关性。
结论
PFPS 患者的症状侧 OLSSB、股四头肌和腘绳肌力量下降，Q 角增大。OLSSB 与疼痛、Q 角和下肢对线之间未检测到相关性，而股四头肌和腘绳肌力量与 OLSSB 之间存在相关性。
临床意义
股四头肌和腘绳肌强化可能有益于改善 PFPS 患者的 OLSSB。
