چکیده

Postural stability of older subjects can be estimated during orthostatic equilibrium. However, dynamic equilibrium is also important to investigate risks of fall. It implies different interpretations of measures given by force plates. Same dependant variables (e.g. center of pressure displacement) cannot be interpreted the same ways depending of the type of equilibrium that is investigated. In particular, sways increases during dynamic equilibrium and before movement execution may reflect an improvement of feedforward control.

بررسی هماهنگی های وضعیتی پیش بینانه هنگام اعمال اغتشاش ارادی در زنان مبتلا به مالتیپل اسکلروزیس

  Background: Impairment of balance control is one of the most disabling symptoms in Multiple Sclerosis (MS). It is known that, in the presence of a predictable postural perturbation, the Central Nervous System (CNS) utilizes Anticipatory Postural Adjustments (APAs) to maintain balance while standing. The main purpose of the current study was to investigate the APAs during self-induced postural...

Enhancing Anticipatory Postural Adjustments: A Novel Approach to Balance Rehabilitation

Balance impairment is common in individuals with neurological disorders and older adults and is a major cause of falls in these populations. Evidence on the effectiveness of conventional interventions for balance restoration is limited. We describe a novel approach to balance rehabilitation that is based on enhancing anticipatory postural adjustments.
