Coming to stand from supine is a motion that most of us do at least once a day. This motion also must be re-taught to those who have suffered injury to the central nervous system. This study was designed to determine the most common patterns used by individuals to come to stand from supine. Three different speeds of motion were used to determine if the pattern changes if the speed of the motion is changed. Thirty adults, ages 22 to 40, were videotaped while rising from a supine position on the floor. This activity was performed twice at each of three speeds. Analysis was then done using the upper extremity, lower extremity, and trunk categories developed by VanSant (1983). A great variance was seen between subjects in the movement patterns used to stand up. One pattern occurred most commonly at each of the three speeds. In this pattern the legs went through an asymmetrical squat, one hand left the floor earlier than the other, and the trunk rotated slightly to one side after it started out symmetrically. No significant difference was found between the motions which occurred at the three different speeds. Eighty-seven percent of the subjects showed change in at least one of the movement categories as the speed was varied. Close analysis of the data revealed a trend toward the motion being more symmetrical at the slow speed and more asymmetrical at the fast speed in those subjects who showed any change.
