This study was conducted to determine the validity of estimating quadriceps femoris muscle bulk with girth measurements in individuals with chronic unilateral patellofemoral pain. Testing included measurements of thigh girth and B-mode ultrasound scans of quadriceps femoris muscle thickness in 26 males and 18 females. Comparison of the control and symptomatic limbs demonstrated significant reductions in muscle thickness in both the male (p < 0.000) and female (p < 0.007) subjects. No significant differences were noted at either the midthigh or suprapatellar girths between limbs, except in the male subjects at the midthigh site (p < 0.006). Estimating muscle atrophy with girth measurements was more accurate in the male versus the female subjects. Clinicians should realize that very small reductions in thigh girth (1%) may be an indicator of significant reductions in muscle bulk (13%), in individuals with prolonged joint pain and disability. Even though the assessment of quadriceps muscle atrophy with girth measurements is somewhat inaccurate, girth measurements probably remain clinically useful.

本研究旨在确定通过测量大腿围度来评估慢性单侧髌股疼痛患者股四头肌体积的有效性。测试包括对 26 名男性和 18 名女性的大腿围度进行测量，并对股四头肌厚度进行 B 型超声扫描。对对照组和症状组的比较表明，男性（p<0.000）和女性（p<0.007）受试者的肌肉厚度均显著降低。除了男性受试者的大腿中段部位（p<0.006）外，四肢之间的中大腿或髌上围度没有显著差异。用围度测量估计肌肉萎缩在男性比女性受试者中更准确。临床医生应该认识到，在患有长期关节疼痛和功能障碍的个体中，大腿围度的微小减少（1%）可能是肌肉体积显著减少（13%）的指标。尽管用围度测量评估股四头肌萎缩有些不准确，但围度测量可能仍然具有临床意义。J Orthop Sports Phys Ther 1987;9(5):177-183。
