Multidomain interventions have shown tremendous potential for improving cognition in older adults. It is unclear if multidomain interventions can be delivered remotely and whether remote intervention is beneficial for older adults who are vulnerable or at risk of cognitive decline. In a 26-week multi-site, home-based, double-blind, randomized contr...
Article
Background: Falls can strongly impact older people’s quality of life, health, and lifestyle. Multifactorial assessment can determine an individual’s risk of falling as the first step for fall prevention intervention. Physiotherapists have an essential role to play in assessing fall risk by older adults living in the community. In the absence of pub...

Background: The proportion of the world population aged over 65 years is increasing in the world population. Quality of life is an important factor in the biopsychosocial management of older patients. The Older People's Quality of Life-35 (OPQOL-35) questionnaire was developed specifically for assessment of the quality of life of older people. The...

Background: The proportion of older people aged more than 65 years old is continuously increasing in the world population. The quality of life is an important factor in their biopsychosocial handling. The questionnaire “Older People’s Quality of Life-35” (OPQOL-35) has been specially developed for the assessment of the senior’s quality of life. The...
Article
Full-text available
Background: In older adults, multidomain training that includes physical and cognitive activities has been associated with improvement of physical and cognitive health. The goal of the multisite StayFitLonger study is to assess a home-based computerised training programme, which combines physical exercises, stimulating cognitive activities and vir...

Full-text available
Despite recent advances in prosthetics, many upper limb amputees still use prostheses with some reluctance. They often do not feel able to incorporate the artificial hand into their bodily self. Furthermore, prosthesis fitting is not usually tailored to accommodate the characteristics of an individual’s phantom limb sensations. These are experience...

Article
Full-text available
A hand amputation is a highly disabling event, having severe physical and psychological repercussions on a person’s life. Despite extensive efforts devoted to restoring the missing functionality via dexterous myoelectric hand prostheses, natural and robust control usable in everyday life is still challenging. Novel techniques have been proposed to...

Background Fall prevention interventions with home-based exercise programmes are effective to reduce the number and the rate of falls, by reducing risk factors. They improve balance, strength, function, physical activity, but it is known that older adults’ exercise adherence declines over time. However, it is unclear which delivery-modalities of th...

Study design: Randomised, controlled, single-blind crossover design study. Objective: Effect of indoor wheelchair curling training on trunk control of a person with chronic spinal cord injury (SCI). Setting: SCI Centre of Balgrist University Hospital in Zurich, Switzerland. Methods: The trunk control of 13 subjects was assessed by the modifi...

During the past 60 years scientific research proposed many techniques to control robotic hand prostheses with surface electromyography (sEMG). Few of them have been implemented in commercial systems also due to limited robustness that may be improved with multimodal data. This paper presents the first acquisition setup, acquisition protocol and dat...

Introduction : the fear of falling seems to be a real problem in the spinal cord injured’s daily life. It is important to be able to evaluate it. To address this issue, a questionnaire has been developed, the « Spinal Cord Injury-Falls Concern Scale » (SCI-FCS). Objectives : this study aims to evaluate of the construct validity and the accuracy of...

Introduction Les chutes sont un des problèmes principaux de santé qui affectent la qualité de vie des personnes âgées. Certains facteurs de risque de chute seraient fortement associés à la qualité de vie des personnes âgées. Pour agir sur ces facteurs, des programmes d’exercices ont été mis sur pied. Bien que les effets de ces programmes d’exercice...

Improving the functionality of prosthetic hands with noninvasive techniques is still a challenge. Surface electromyography (sEMG) currently gives limited control capabilities; however, the application of machine learning to the analysis of sEMG signals is promising and has recently been applied in practice, but many questions still remain. In this...

The natural control of robotic prosthetic hands with non-invasive techniques is still a challenge: myoelectric prostheses currently give some control capabilities; the application of pattern recognition techniques is promising and recently started to be applied in practice but still many questions are open in the field. In particular, the effects o...

In this paper we characterize the NINAPRO database and its use as a benchmark for hand prosthesis evaluation. The database is a publicly available resource that aims to support research on advanced myoelectric hand prosthetics. The database is obtained by jointly recording surface electromyography signals from the forearm and kinematics of the hand...

Recent advances in rehabilitation robotics suggest that it may be possible for hand-amputated subjects to recover at least a significant part of the lost hand functionality. The control of robotic prosthetic hands using non-invasive techniques is still a challenge in real life: myoelectric prostheses give limited control capabilities, the control i...

INTRODUCTION and AIM Patients with injuries to spinal cord often exhibit a limited ability to sit unsupported, due to sensory loss and paralysis of trunk muscles. Because unsupported sitting is of utmost importance in daily life activities, it is a privileged target during rehabilitation. However, in order to improve the follow-up of patients, ther...

The purpose of this prospective cohort study was to determine whether the maximal width of the base of support (BSW) measure is able to predict the risk of multiple falls in community-dwelling women. 38 community-dwelling women (mean age of 72 ±8 years old) participated. Falls were prospectively recorded during the following year. Overall, 29 falls...

The one minute sit-to-stand test evaluates the muscular strength and balance of the lower limb. The goals of this study are to evaluate with an accelerometer (Myotest care®) the muscular strength and power avarage during this test and their change over one minute and to etablish norms for an active population. This cross-sectionnal study was conduc...

The aim of this study was to test the reliability and validity of a preferred-standing test for measuring the risk of falling. The preferred-standing position of elderly fallers and non-fallers and healthy young adults was measured. The maximal BSW was measured. The absolute and relative reliability and discriminant validity were assessed. The expa...

Currently, trans-radial amputees can only perform a few simple movements with prosthetic hands. This is mainly due to low control capabilities and the long training time that is required to learn controlling them with surface electromyography (sEMG). This is in contrast with recent advances in mechatronics, thanks to which mechanical hands have mul...

Home-based exercise programmes can substantially contribute to a successful rehabilitation. Adherence to unsupervised exercise programmes is often not optimal. A team of health professionals (physiotherapists, nurses, occupational therapists, psychologists, sports scientists and medical doctors), social workers and e-health specialists tries to improve the methods of delivering exercise programmes.
