We hypothesize that the combination of obesity and knee osteoarthritis is responsible for altered knee and hip kinetics and an increase in time during STS transfer, rather than knee osteoarthritis alone. Lefevre-Colau, F. BioMed Eng OnLine 8, 27 Because of these mechanical demands, there are many elderly people who experience difficulty when standing up from a chair [ 45 ]. An STS movement requires a peak joint moment greater than other movements such as stair climbing or walking [ 1 ], and yields peak hip joint contact pressure higher than other movements such as walking, jogging or jumping [ 2 ].
