Increased physical activity has been demonstrated as a relevant treatment after a stroke, with positive effects on impairment recovery, activity limitation, social participation and quality of life. Furthermore, PA is now recommended as part of the stroke recovery pathway, starting during inpatient care and extending through rehabilitation and community integration. The purpose of this presentation is to describe how current technologies may facilitate a continuity of care for stroke survivors.

Background: The main aim of this paper is to present the feasibility of rigorously designed multiple N-of-1 design in prosthetics research. While research of adequate power and high quality is often lacking in rehabilitation, N-of-1 trials can offer a feasible alternative to randomized controlled group trials, both increasing design power at group level and allowing a rigorous, statistically confirmed evaluation of effectiveness at a single patient level. The paper presents a multiple N-of-1 trial protocol, which aim is to evaluate the effectiveness of Unity, a prosthetic add-on suspension system for amputees, on patient-reported comfort during daily activities (main outcome measure), prosthesis wearing time, perception of limb-prosthesis fitting and stump volume and functional walking parameters.

Article Synopsis
  • Telerehabilitation, particularly through exergaming technology, is being used to help stroke patients with upper limb impairments improve their mobility and engage in enjoyable training exercises at home.
  • The review assesses user compliance with exercise programs based on how often patients complete prescribed sessions and how many drop out or discontinue the exercises.
  • Results show high compliance rates, but dropout reasons often stem from external factors or tech issues; there's a need for long-term follow-ups and better understanding of support systems like home visits.

Foot drop is a common disability in post-stroke patients and represents a challenge for the clinician. To date, ankle foot orthosis (AFO) combined with conventional rehabilitation is the gold standard of rehabilitation management. AFO has a palliative mechanical action without actively restoring the associated neural function.

Article Synopsis
  • Increased energy costs of walking (Cw) in stroke patients are linked to their walking ability and independence, but the effect on their quality of life (QoL) has not been previously explored.
  • A study with 37 stroke patients found that higher Cw significantly impacted QoL assessments taken after hospital discharge, particularly at six months and one year later.
  • The findings suggest that both Cw and mood disorders (measured by HADS) are important predictors of QoL, emphasizing the need for early interventions to improve these factors for better long-term outcomes.

Background: The current coronavirus disease (COVID-19) pandemic makes it difficult to obtain physical therapy in rehabilitation centres, particularly for persons with multiple sclerosis (pwMS), who are a population at high risk, since viral infections may contribute to MS exacerbations and relapses. Active video games could be a way to maintain physical therapy at home as part of the rehabilitation. The aim of this review is to summarise the current best evidence for the effectiveness of home-based active video games on gait and balance, user compliance, feasibility and safety for pwMS.

Introduction: Visuo-spatial working memory (VSWM) performances undergo a decline throughout aging and are affected by the space in which the task is performed (reaching or navigational). Cerebral oxygenation and cognitive capabilities could explain this decline. We assessed the effects of age on cerebral oxygenation of the dorsolateral prefrontal cortex (dlPFC) in VSWM tasks in reaching and navigational space.
