Active and passive contributions to joint kinetics during walking in older adults.
The objectives of this study were to characterize the active and passive contributions to joint kinetics during walking in healthy young and older adults, and assess whether isokinetic ankle strength is associated with ankle power output during walking. Twenty healthy young (18-35 years) and 20 healthy older (65-85 years) adults participated in this study. We measured subject-specific passive-e...
متن کاملThe contribution of passive-elastic mechanisms to lower extremity joint kinetics during human walking.
The purpose of this study was to investigate the contribution of passive mechanisms to lower extremity joint kinetics in normal walking at slow, comfortable, and fast speeds. Twenty healthy young adults participated in a passive testing protocol in which the relaxed lower limb was manipulated through full sagittal hip, knee, and ankle ranges of motion while kinematics and applied forces were si...
متن کاملPassive and Active Contributions to Glenohumeral Stability
Fresh-frozen shoulder specimens were used to evaluate restraining forces provided by capsuloligaments and muscles crossing the glenohumeral (GH) joint to better understand various factors contributing to GH stability. The humeral head was translated in the posterior-anterior (PostAnt), inferior-superior (Inf-Sup), and medial-lateral (MedLat) directions, and rotated about the humeral long axis r...
متن کاملActive and passive contributions to spatial learning.
It seems intuitively obvious that active exploration of a new environment will lead to better spatial learning than will passive exposure. However, the literature on this issue is decidedly mixed-in part, because the concept itself is not well defined. We identify five potential components of active spatial learning and review the evidence regarding their role in the acquisition of landmark, ro...
متن کاملContributions of cognitive function to straight- and curved-path walking in older adults.
OBJECTIVE To determine whether the cognitive function contribution to straight- and curved-path walking differs for older adults. DESIGN Cross-sectional observational study. SETTING Ambulatory clinical research training center. PARTICIPANTS People (N=106) aged 65 to 92 years, able to walk household distances independently with or without an assistive device, and who scored 24 or greater o...
