(A) Lequesne index and quadriceps strength of patients with knee OA. As quadriceps strength decreased the patient’s disability increased (rs =−0.385, p<0.001).
(A) Lequesne index and quadriceps strength of patients with knee OA. As quadriceps strength decreased the patient’s disability increased (rs =−0.385, p<0.001). Mean quadriceps strength decreased in each arbitrarily defined category of disability (p<0.001). (B) Lequesne index and the aggregate functional performance time of the patients with knee OA. As the Lequesne index for disability increased the aggregate time of the tests increased (rs=0.665, p<0.001). The mean AFPT increased at each arbitrarily defined level of disability (p<0.001).
