About

The present study investigated whether the presence of fluid in the joint affected peak torque and the root mean square (RMS) values of surface electromyography (EMG) in patients symptomatic for osteoarthritis (OA).

Full description

Several studies have shown that knee effusion influenced quadriceps muscle activity and induced quadriceps arthrogenic muscle inhibition in normal volunteers. However, the effect of joint effusion on the quadriceps of patients with OA is controversial,and few patients with OA have been included in studies of joint effusion.
