GAIT POSTURE , 2005, vol. 22, n° 4, p. 338-345 Doc n°: 122991 Localisation : Documentation IRR Descripteurs : DF22 - EXPLORATION EXAMENS BILANS - MARCHE, CD1 - ETUDES GENERALITES - RACHIS DORSAL ET CHARNIERE DORSO-LOMBAIRE, DE12 - EXPLORATION EXAMENS BILANS - MEMBRE INFERIEUR, DF15 -SIT-TO-STAND This study aimed to determine the sagittal movement relationships between thoracic, lumbar spine and hip joints during sit-to-stand (STS). Forty-seven healthy young adults were videotaped performing STS at their preferred speed from a chair set at 100% knee height. Forward trunk lean prior to buttock lift-off (LO) was accomplished by concurrent lumbar and hip flexion (1:3). As the lumbar spine flexed the thoracic spine extended, resulting in a LO trunk angle of 45.7 degrees (+/- 5.8 degrees) with respect to a horizontal reference. Following LO, the hip(s) and lumbar spine extended and the thoracic spine flexed, with the standing thoracic angle approximating the initial thoracic posture in sitting. (c) 2004 Elsevier B.V.
