METHODS: Cross-sectional study, where fifty-five women with PFP were submitted to the following evaluations: (1) muscle thickness (MT) of Gluteus Medius (GMed), Gluteus Maximus (GMax), Vastus Lateralis (VL), and Tibialis Anterior (TA); (2) isometric peak torque of hip abductors, hip external rotators, knee extensors, and foot inversors; and (3) DKV during SLS.
RESULTS: There was a significant negative association between GMax\'s MT and DKV (r = -0.32; p = 0.01), and between TA\'s MT and DKV (r = -0.28; p = 0.03). No significant correlations were observed between isometric torques and DKV. Regression analysis found that GMax\'s MT explained 10% of the DKV\'s variance during SLS.
CONCLUSIONS: Poor lower limb alignment during SLS is weakly associated with proximal and distal-to-the-knee muscle thicknesses, with no association with isometric torque in PFP women.
CONCLUSIONS: Our results suggest that other factors besides strength and muscle thicknesses may explain and improve lower limb alignment in women with PFP.
方法:横断面研究,其中55名患有PFP的女性接受了以下评估:(1)GluteusMedius(GMed)的肌肉厚度(MT),GluteusMaximus(GMax),腹肌(VL),和胫骨前肌(TA);(2)髋关节外展肌的等距峰值扭矩,髋部外部旋转器,膝盖伸肌,和脚力;和(3)SLS期间的DKV。
结果:GMax的MT与DKV之间存在显着负相关(r=-0.32;p=0.01),在TA的MT和DKV之间(r=-0.28;p=0.03)。在等距扭矩和DKV之间没有观察到显着的相关性。回归分析发现,GMax的MT解释了SLS期间DKV方差的10%。
结论:SLS期间下肢排列不良与膝关节近端和远端肌肉厚度弱相关,与PFP女性的等距扭矩无关。
结论:我们的结果表明,除了力量和肌肉厚度之外,其他因素也可以解释和改善PFP女性的下肢排列。
