The study investigated whether physiological factors related to specific body systems can explain postural control as measured by the scalar distance at a given time between the center of pressure (COP) and the center of mass (COM), the COP-COM variable. The data from 46 healthy subjects and 29 subjects with disabilities due to stroke or diabetic peripheral(More)
OBJECTIVES To estimate the test-retest and interrater reliability of the center of pressure-center of mass (COP-COM) variable of postural control in the elderly. DESIGN The biomechanic variable COP-COM, which represents the distance between the COP and the COM, was determined from 2 AMTI force platforms and 3 OPTOTRAK position sensors. Measurements were(More)
OBJECTIVES To estimate the intrasession reliability of a single measure of the biomechanical variable "center of pressure minus center of mass" (COP-COM) to determine, first, how many trials must be averaged to obtain a reliable measure of postural stability, and second, the minimal metrically detectable change of the COP-COM.

Teleoperated from a distant location, a mobile robot with some autonomous capabilities can become a beneficial tool in telehealth applications. Assistive technologies for telementoring in homes constitute a very promising avenue to decrease load on the health care system, reduce hospitalization period and improve quality of life. However, design issues(More)
OBJECTIVE The objective of the present study was to compare postural mechanisms identified by using dual force platform in healthy elderly community-dwelling subjects and diabetic sensory neuropathy (DSN) patients under different visual conditions. RESEARCH DESIGN AND METHODS The presence and the severity of the sensory neuropathy was evaluated with a(More)

OBJECTIVE The objective of this study was to compare clinical and biomechanical characteristics of balance in diabetic polyneuropathic elderly patients and normal age-matched subjects. RESEARCH DESIGN AND METHODS Fifteen elderly with distal neuropathy (DNP) and 15 healthy age-matched subjects were evaluated with the biomechanical variable COP-COM, which(More)
In a prospective study of 225 community dwelling people 75 years and older, we tested the validity of the Tinetti balance scale to predict individuals who will fall at least once during the following year. A score of 36 or less identified 7 of 10 fallers with 70% sensitivity and 52% specificity. With this cut-off score, 53% of the individuals were screened(More)
Mobile robots operating in home environments must deal with constrained space and a great variety of obstacles and situations to handle. This article presents a pilot study aiming at identifying design specifications of a new user interface and robot specifications to improve efficiency and security for novice teleoperators of a mobile robot used in home(More)
INTRODUCTION Gait retraining approaches and walking aids currently used for patients with recent stoke present limitations regarding their utilization in clinical and real life settings. A rehabilitation facility implemented an innovative approach using a rehabilitation dog for gait retraining and as a walking aid. OBJECTIVE To explore the effectiveness(More)
We examined the requirements for robots in home telecare using two focus groups. The first comprised six healthcare professionals involved in geriatric care and the second comprised six elderly people with disabilities living in the community. The concept of an in-home telepresence robot was illustrated using a photograph of a mobile robot, and participants(More)
