Objective: The aim of this study is to compare the efficiency of vision-obscured versus vision-retained treadmill gait training in subacute post-stroke patients.
Methodology: Thirty-six patients with stroke (ischemic or hemorrhagic) less than six months old will be included and randomized into two parallel groups. The experimental group will undergo treadmill gait training using an opaque mask, combined with body weight reduction (Lite Gait® harness). The control group will follow the same walking protocol, but with their eyes open. Each session will last 20 minutes, integrated into one hour of rehabilitation, at a rate of three sessions per week for six weeks. Assessment will include single- and double-task walking speed, balance parameters and proprioception.
Expected results: The hypothesis is that visual deprivation will stimulate the proprioceptive and vestibular systems to a greater extent, resulting in benefits for postural balance, walking and proprioception. The main hypothesis will be the improvement in the difference between single-task and double-task walking speed. Analyses will be conducted on an intention-to-treat basis, using statistical tests adapted to the nature of the variables.
Conclusion: This study could highlight the value of temporary visual suppression as a therapeutic lever in stroke rehabilitation.
