Sit-to-stand and stand-to-sit kinematics in older adults with and without functional disability: A principal component analysis.

ABSTRACT:

Objective

Sit-to-Stand (Sit-TS) and Stand-to-Sit (Stand-TS) transitions are essential daily movements affected by ageing and disability. This study aimed to explore related kinematic domains in older adults with and without disability.

Methods

A cross-sectional study including adults aged 60 years or older, with (n = 25) and without disability (n = 35). Comparisons between groups included task time, centre of mass (CoM) acceleration, postural sway and principal component (PC) scores for each task. Principal component models (PCMs) included lower limb and trunk tridimensional joint ranges of motion, angular velocity range, CoM displacement and velocity along each Sit-TS (flexion, momentum transfer, extension and stabilisation) and Stand-TS (initiation, flexion, momentum trans
