In the recruitment test of tibialis anterior and vastus medialis all the parameters of the MUP from slight muscle contraction were more sensitive than those from moderate muscle contraction .

在胫前肌和 股 四 头 肌，轻度比中度用力收缩MUP各项参数的诊断作用更加敏感。

Activation Characteristics of Vastus Medialis Rectus Femoris and Vastus Lateralis Muscles in Patients with Knee Osteoarthritis and Health Subjects

膝骨关节炎患者与正常人 股 内侧 肌、股直肌和股外侧肌收缩特征的对照研究

Anatomical abnormalities should be responsible for the condition such as increased Q angle a high-riding patella dysplasia of the femoral condyles abnormal shape of the patella atrophy of the vastus medialis and hypertrophy of the vastus lateralis .

其发病的主因是患者存在膝关节解剖结构异常，如Q角增加、髌骨高位、股骨外髁发育不良、髌骨形态异常、 股 直肌 内侧 头萎缩或股直肌外侧 头肥大等。

Applied Anatomy of the Vastus Medialis Muscle Flap

股 内侧 推进肌瓣的应用解剖

Method From the vastus medialis tibialis anterior and abductor pollicis brevis muscles 1903 MUP in 116 healthy adults ( ranging from 17 to 72 years old ) and 755 MUP in 45 neurogenic patients were registered with concentric needle electrodes .

方法116名健康成人和45例神经原性疾病患者的拇短展肌、胫前 肌 和 股 四 头肌的 2658个 MUP，通过棘波触发平均技术得到记录。

The key content is to pay attention to the treatment to the pathological axis ( lumbar vertebra-obturator nerve-adductor muscle of vastus medialis ) .

其核心内容为重视对腰椎-闭孔神经- 股 内收肌病理轴的治疗；

Major development effort to achieve the maximum force the muscle part of the order of the vastus medialis muscle erector spinae latissimus dorsi deltoid muscle after the beam biceps tibialis anterior muscle .

各主要发力肌肉的达到最大用力环节顺序是 股 内侧肌、竖脊肌、背阔肌、三角肌后束、肱二头肌、胫骨前肌。

The electromyograph was used to record and test the response time of the examinees on spinal reflex intermediate reflex and voluntary muscle activities of muscle vastus medialis and gastrocnemius before right after the exercise and 4 hours after recovery .

于运动前、运动后即刻和恢复4h采用肌电图仪分别记录受试者 股 内侧 肌和腓肠肌的肌肉反应时，包括脊髓反射、中间反射和自主肌肉活动肌肉反应时。

Conclusions The main causes of patellar subluxation consisted of patella alta the Q angle raised patellar type ⅱ and ⅲ of Wiberg shapes thickening and tightness of the lateral retinaculum and insufficient of vastus medialis obliquus muscle function .

结论髌骨半脱位病因主要与高位髌骨、过大的Q角、外侧支持带的挛缩肥厚、髌骨的发育类型以及 股 四 头 肌 内侧 头肌张力不良有关。
