Trunk-flexor muscle strength plays a fundamental role in athletic performance, 1 – 3 health of children and adolescents, 4 , 5 posture, and rehabilitation. It is also vital for core stability 6 , 7 and situations such as urinary incontinence and athletes’ rehabilitation. 8 Therefore, accurate

Paralympic cross-country (XC) sit-skiing is a Paralympic discipline in which athletes are skiing seated because they have an impairment in function or structure of the lower extremities, pelvis, and/or trunk. XC sit-skiers ski using a sledge mounted on a pair of XC skis, named sit-ski, and a couple

versus nondominant hop medial landing ( P  = .05). Discussion This study set out to determine whether trunk-mounted accelerometry could quantify postural sway during hop landing. Previous studies have demonstrated the use of trunk-mounted accelerometry for measuring balance. The findings of this study

, & Ho, 2001 ; Lynn & Costigan, 2009 ). In addition, patients with OA tend to adopt a gait with lateral trunk sway to the affected side to reduce the moment arm of the ground reaction force to the knee joint center, resulting in a reduction of the external knee adduction moment ( Hunt et al., 2008

Parkinson’s disease 10 and low back pain, 11 – 13 do not adapt their relative phase timing at higher velocities. Moreover, the increase in relative phase between the axial rotations of the upper trunk (thorax, from C7 to T12) and the pelvis of typical individuals is mostly due to the change in timing of

Paralympic sports, a classification system exists in order to minimize the impact of impairment on the outcomes of competition. 2 Classification in WR is largely dependent on the physical assessment of trunk and arm function. Point scores between 0 and 1.5 are awarded to represent trunk function. Both arms
