Complex walking tasks, including change of direction, patterns and rhythms, require more attentional resources than simple walking and significantly impact walking performance, especially among ageing and neurological populations. More studies have been focusing on complex walking situations, with or without the addition of cognitive tasks, creating a multitude of walking situations. Given the lack of a clear and extensive definition of complex walking, this narrative review aims to identify and more precisely characterize situations and related tests, improve understanding of behavioral adaptations in ageing and neurological populations, and report the clinical applications of complex walking.

Immersive virtual patient simulation could help medical students in clinical reasoning, but there is a lack of literature on the effectiveness of this method in healthcare learning. A pilot randomised controlled study compared performance (exam score) on a clinical case in immersive virtual simulation to a text for physiotherapy students. In the experimental group, the clinical case was presented by an immersive 360° video that students watched with a standalone headset, whereas the control group used the text only.

Objective: The development of negative behavioral and psychosocial factors (depression, anxiety, apathy, etc) is associated with poor well-being, which can contribute to health issues in ageing, especially in the context of COVID-19. Despite its relative novelty, fully immersive virtual reality (VR) interventions through 360° immersive videos are becoming more accessible and flexible and constitute an emerging method to potentially enhance well-being. The aim of this scoping review is to assess the effectiveness of 360° interventions on well-being in older adults with or without cognitive impairment, as well as cybersickness and attitudes toward this technology.

Background and objective: Duration of rehabilitation and active participation are crucial for gait rehabilitation in the early stage after stroke onset. Virtual reality (VR) is an innovative tool providing engaging and playful environments that could promote intrinsic motivation and higher active participation for non-ambulatory stroke patients when combined with robot-assisted gait training (RAGT). We have developed a new, fully immersive VR application for RAGT, which can be used with a head-mounted display and wearable sensors providing real-time gait motion in the virtual environment.

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
  • Stroke patients may have limited use of their affected arms after leaving the hospital, which affects daily activities.
  • Exercise games (exergames) can help maintain arm function and encourage daily use during home rehabilitation.
  • A review of studies found that exergaming was not more effective than conventional therapy for improving arm activity, suggesting future research should explore specific subgroups for better recommendations.

In visual rehabilitation, ground visual field assessment (GVFA) makes it possible to assess the size of scotomas in connection with locomotion and to restore the width of the patient's visual field (VF). The information obtained by these tests has never been compared with Goldmann testing. The purpose of this study was to assess the reproducibility of VF measurement under different conditions (Goldmann perimetry, manual and automated GVFA).

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.

Increasing cerebral oxygenation, more precisely the overactivation of the prefrontal cortex (PFC), reflects cortical control of gait in stroke disease. Studies about the relationship between brain activation and the functional status in stroke patients remain scarce. The aim of this study was to compare brain activation, gait parameters, and cognitive performances in single and dual tasks according to the functional status in subacute stroke patients.
