Fig. 2From: Relationship between movement time and hip moment impulse in the sagittal plane during sit-to-stand movement: a combined experimental and computer simulation studyCalculation of joint angles during the sit-to-stand movement. The angles of the proximal segment relative to the distal segment during the sit-to-stand movement were calculated for each experiment trial. Counterclockwise was defined as plus, and clockwise was defined as minusBack to article page
