Co-contraction is important (and effortful) contraction of one muscle and itsagonistresulting in almost no movement at the articulation. In a neurophysiologic study of 12 subjects with functional leg weakness, it was found that knee flexion was weaker than it would have been just with gravity ...
Weakness was a predictor of whole knee cartilage loss (HR 3.48, 95% CI 1.30-9.35). Quadriceps weakness was associated with cartilage loss in the medial tibiofemoral (TF) compartment (HR 4.60, 95% CI 1.25-17.02), while no significant association was found with lateral TF (HR 1.53, 95% CI...
OBJECTIVES: (1) To determine the importance of quadriceps strength, structural change, and psychological status in terms of knee pain in the community. (2) To determine the relative importance of quadriceps function, structural change, and psychological status with respect to disability in subjects ...
Ultrasound measurements of the rectus femoris cross-sectional area (RFCSA) were performed as part of routine clinical monitoring carried out in the unit. To image the rectus femoris, the patient was positioned at 30 degrees on a suitable bed. The knee was relaxed to prevent artificial contraction...
Involvement of the quadriceps muscle group in knee osteoarthritis is receiving increasing research interest. The motor and sensory functions of muscle are intimately linked, and deficits in the sensorimotor functions of the quadriceps have been identified and proposed as possible factors in the pathogenesi...
