Abstract
The results showed that STA observed at the femur was larger in non-obese subjects than in obese subjects in frontal rotation (pâ¯=â¯0.004), axial rotation (pâ¯=â¯0.000), medio-lateral displacement (pâ¯=â¯0.000) and antero-posterior displacement (pâ¯=â¯0.019), while STA observed at the tibia was lower in non-obese subjects than in obese subjects for the three rotations (pâ¯<â¯0.05) and medio-lateral displacement (pâ¯=â¯0.015). Differences between the markers and bones knee kinematics increased with knee flexion and were similar in both groups, except for abduction-adduction: 4.9° for non-obese subjects against 2.3° for obese subjects (pâ¯=â¯0.011). Significance: This study demonstrated that STA at the femur and its impact on knee abduction-adduction using a specific exoskeleton were greater among non-obese subjects than obese subjects, which is encouraging for future biomechanical studies on pathologies such as osteoarthritis.
