OBJECTIVE This study investigated anticipatory postural adjustments (APAs) and compensatory postural adjustments (CPAs) and their relationship in older adults during lateral postural perturbations. METHODS Unpredictable and predictable postural disturbances were induced by a swinging pendulum that impacted at the shoulder level of two groups of older(More)
The main objective of this study was to analyze the role of balance exercises on anticipatory (APA) and compensatory (CPA) postural adjustments in different conditions of postural stability. Sixteen subjects were required to catch a ball while standing on rigid floor, trampoline and foam cushion surfaces. Electromyographic activities (EMG) of postural(More)
The age-related changes for controlling grip force in adults who practice regular and supervised physical activity have not been investigated. Fifty-five physically active adults ages 50 years and older and a group of 20 young adults (18-30 years old) performed a task of grasping and lifting an object. The grip force and the object's acceleration were(More)
The goal of this study was to investigate the timing of compensatory postural adjustments in older adults during body perturbations in the mediolateral direction, circumstances that increase their risk of falls. The latencies of leg and trunk muscle activation to body perturbations at the shoulder level and variables of center of pressure excursion, which(More)
The purpose of this study was to investigate the anticipatory (APA) and compensatory (CPA) postural adjustments in individuals with Parkinson's disease (PD) during lateral instability of posture. Twenty-six subjects (13 individuals with PD and 13 healthy matched controls) were exposed to predictable lateral postural perturbations. The electromyographic(More)
Small mobile devices for accessing the Internet through wireless access networks have become increasingly common in recent years. In this new context, a major challenge is the adaptation of content to these devices, satisfying their capabilities and user preferences and optimizing the use of wireless access networks. This paper therefore presents a(More)
