To investigate the immediate effect of electrical stimulation of the common peroneal nerve on the maximum voluntary activation of the quadriceps muscle in patients with knee osteoarthritis.
Fifteen subjects with knee osteoarthritis (mean age: 50.5 ± 13 years) participated in this study. To measure the arthrogenic inhibition ratio of quadriceps, a burst of electrical stimulation was superimposed on the maximum voluntary contraction, and the percentage of change in the force production was computed. The same measurement was also performed with concurrent electrical stimulation of the common peroneal nerve.
All the patients with knee osteoarthritis showed significant arthrogenic inhibition of the quadriceps muscle. The stimulation of the common peroneal nerve was able to reduce this inhibition and increase the capacity of the muscle to produce a significantly higher knee extension force (p = 0.028).
Electrical stimulation of the common peroneal nerve concurrent with the maximum voluntary effort can remove the arthrogenic inhibition of the quadriceps muscle in patients with knee osteoarthritis. This finding could have clinical implications in the management of patients with knee disorders.
探讨电刺激腓总神经对膝骨关节炎患者股四头肌最大自主激活的即时效应。
15名膝骨关节炎患者（平均年龄：50.5±13岁）参与了本研究。为测量股四头肌的致关节炎性抑制率，在最大自主收缩时叠加一阵电刺激，并计算力量产生的变化百分比。同时对腓总神经进行电刺激时也进行了同样的测量。
所有膝骨关节炎患者的股四头肌均表现出显著的致关节炎性抑制。腓总神经刺激能够减轻这种抑制，并增加肌肉产生明显更高的膝关节伸展力的能力（p = 0.028）。
在最大自主用力的同时电刺激腓总神经可消除膝骨关节炎患者股四头肌的致关节炎性抑制。这一发现可能对膝关节疾病患者的管理具有临床意义。
