of the position of the hands, irregular movement strategies were classified and clustered among the 3 major clusters of the 3-cluster solution. At trials A3, A4, and Q5, participants kept their hand(s) close to the seat at the height of their pelvis until completion of the standing movement. As a

, Harrison, & Troyanovich, 1999 ). For example, Bolin et al. ( 2000 ) reported that persons with SCI have impaired balance with a C-shaped sitting posture and a posteriorly tilted pelvis (about 15°) compared with noninjured persons in a neutral position. In addition, Andersson et al. ( 1974 ) showed that the

validated by Thorborg et al. 38 For hip abduction strength testing, the HHD was placed 10 cm proximal to the lateral femoral epicondyle and the hip was placed in approximately 30° of abduction. The contralateral hip was flexed to 90° and neutral relative to rotation. The examiner stabilized the pelvis to

-executed SLSq consists of an erect trunk, a level pelvis (frontal plane), a neutral hip position with no internal rotation (IR) or adduction, and the central knee aligned over the second toe during motion. 7 One of the key measures of lower limb dysfunction during SLSq is knee valgus. Knee valgus, which can

A 4-segment model was built from the raw marker trajectories in the Visual 3D software suite (C-Motion Inc, Germantown, MD). Specifically, the model included the pelvis, thigh, leg

positive power. Alternatively, pelvis position, rather than trunk position, is also suggested to affect age-related differences in hip position, 11 , 20 and in effect, hip kinetics, and has a more direct effect on hip angle than trunk position. Manipulating the pelvis angle during gait is challenging, but

Age-related reductions in arm swing and head–trunk–pelvis

In children, jump height increases with age, standing height, and mass ( 2 ). To assess whether differences in jump height were
