Knee and hip kinetics during normal stair climbing

摘要: Understanding joint kinetics during activities of daily living furthers our understanding the factors involved in pathology and effects treatment. In this study, we examined hip knee stair climbing 35 young healthy subjects using a subject-specific model to estimate bone-on-bone tibiofemoral patello-femoral contact forces. The net forces were below one body weight while peak posterior-anterior force was close weight. distal-proximal on average 3 times could be as high 6 These occurred at degree flexion where there is smaller area resulting stresses. adduction moment 0.42 (0.15) Nm/kg 1.16 (0.24) Nm/kg. Similar values, but different curve profiles, found for hip. shear higher than level walking. most striking difference between ascent walking that 8 ascent. data can used baseline measures studies, input theoretical models, mechanical simulators.
