The Influence of Radiographic Severity on the Relationship between Muscle Strength and Joint Loading in Obese Knee Osteoarthritis Patients
Figure 3
Whole cohort linear relationships obtained by mixed linear regression between lower extremity peak muscle strength and peak knee adduction moments during self-selected walking speed. Quadriceps is depicted in (a) and hamstrings in (b). Grey-dashed lines indicate 95% confidence intervals. N: Newton, m: meter, BW: body weight, HT: height. Covariates used in the statistical model: age, gender, walking speed, body mass, knee joint alignment, and knee joint pain. Level of significance .
