Balance; Distorted

This research focuses on the effects of rehabilitation on balance, in patients with acquired chronic demyelinating neuropathy. Rehabilitation will be performed with or without vision. It is planned to include 40 subjects consulting for walking instability related to sensitivity disorders. This multicenter study will take place in Paris's area. Each participant will benefit from 20 rehabilitation sessions with a Physical Therapist and 3 assessments. Thanks to randomization, patient will be allocated in one of the 2 following groups: * Control group, Patients will benefit from balance rehabilitation with open eyes. * Experimental group, they will perform the same exercises while keeping their eyes closed or their vision will be obstructed by a mask or disturbed by moving luminous dots projected on the environment in darkness.

This study will evaluate the effects of combining balance training with electrical stimulation techniques in individuals with Multiple Sclerosis (MS). MS commonly impairs leg strength, coordination, and balance, increasing the risk of falls and reducing independence. The interventions include:Balance training only, Balance training with Functional Electrical Stimulation (FES), and Balance training with FES and Transcutaneous Spinal Cord Stimulation (TSCS). FES delivers small electrical pulses to leg muscles, while TSCS delivers electrical signals through the skin to stimulate the spinal cord and enhance motor control. The study will enroll up to 24 participants over a 3-year period. This trial is funded by MS Canada. Participants will be randomly assigned to one of three groups: (1) balance training only, (2) balance training with FES, or (3) balance training with FES and TSCS. All participants will complete 12 supervised training sessions over 6 weeks. During each session, participants will engage in interactive balance games while standing in a safety harness.Outcome assessments will be conducted at three time points: baseline (prior to training), post-intervention (after 6 weeks), and follow-up (8 weeks after training). Assessments will include: * Clinical tests of mobility and balance (Timed Up and Go:TUG, 10-Meter Walk Test:10MWT, Berg Balance Scale:BBS) * Computerized balance testing using a force plate * Questionnaires on walking ability, fear of falling, and balance confidence * Neurophysiological measures of brain-spinal cord-muscle communication before and after training

The purpose of the study is to investigate dynamic core stability training versus cognitive training on balance, functional performance, postural control, ankle instability scores, ankle dorsiflexion range of motion, and mental workload in chronic ankle instability

To compare effects of otago exercises and Gaze stabilization exercises on Balance, gait and quality of Life in elderly stroke patients

The aim of this study is to determine the factors affecting falls in patients with COPD.
