Clinical Trial: Effects of Joint Effusion on Quadriceps Muscle

Study Status: Completed
Recruit Status: Completed
Study Type: Interventional

Official Title: Effects of Joint Effusion on Quadriceps Muscle in Patients With Knee Osteoarthritis

Brief Summary: 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).

Detailed Summary: 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.

Current Primary Outcome: the peak torque of the knee extensors [ Time Frame: within 5 minutes after intervention ]

to evaluate the effect of effusion on the peak torque of the knee extensors


Original Primary Outcome: Same as current

Current Secondary Outcome: the root mean square values of the vastus medialis and vastus lateralis muscles [ Time Frame: within 5 minutes after intervention ]

to evaluate the effect of effusion on the RMS of the vastus medialis (VM) and vastus lateralis (VL) muscles


Original Secondary Outcome: Same as current
