This study wan described the movement patterns when rising from supine to erect stance in the third through eighth decades. Two hundred fifty six subjects, ranging in age from 30 year to 89 were filmed while rising from a supine position. Movement patterns were classified using categorical descriptions of the action of the upper and lower extremity, head-trunk region. This study was designed to determine whether within the rising task the movement patterns of different regions of the body vary with age level and sex, to describe time by subjects to perform this task. The incidence of each movement pattern was calculated and graphed wi th respect to age level and sex. Erect standing time was increased by age increasing in beth sex group. The most common form of rising for subject in the third through fifth decades both sex usually involved symmeytrical push with upper extremity, symmetrical squat pattern with lower extremity, partial rotation pattern wi th head-trunk and symmetrical push to push and reach pattern with upper extremity, symmetri cal squat pattern with lower extremity. partial rotation with head-trunk. In the sixth through eighth decades usually involved symmetrical push to push and reach pattern with upper extremity, symmetrical squat pattern with lower extremity, partial rotation pattern with head-trunk in both sex group.
