Effect of Immersive Virtual Reality Cognitive Rehabilitation on Subacute Stroke Patients (A Pilot Study)

This pilot randomized controlled trial aims to evaluate the effectiveness of cognitive rehabilitation using an immersive Virtual Reality (VR) system compared to conventional paper-and-pencil cognitive training in subacute stroke patients. A total of 22 participants will be randomly assigned to either the VR intervention group (n=11) or the conventional control group (n=11). The study will measure changes in cognitive function and functional independence

Phase I Split-Belt Treadmill Dosing for Subacute Stroke

After experiencing a stroke, many individuals encounter difficulties with walking and balance, which can significantly impact their independence. Recent studies have indicated that split-belt treadmill (SBT) training is effective for improving gait metrics, including walking speed and step length asymmetry. The SBT allows each leg to move at different speeds, which has been shown to help chronic stroke survivors learn to walk more symmetrically. However, there is limited knowledge about the dose participants should receive and the safety of SBT training in the early stages of recovery, which is a crucial period for rehabilitation. To address this gap, we are evaluating an innovative SBT with virtual reality (VR) features at the Foothills Medical Center. Our objective is to conduct a study to determine the amount of SBT training patients can tolerate in a day. In this study, stroke survivors will engage in a series of walking exercises on the SBT. We will escalate the duration of SBT walking until participants reach a point where they can no longer continue due to dose-limiting criteria such as fatigue or discomfort. The findings from this initial phase will guide future larger trials to explore the effectiveness of this training method. Ultimately, we aspire to improve rehabilitation strategies for stroke survivors, assisting them in regaining mobility and enhancing their quality of life more effectively.

Comparative Effects of Functional Electrical Stimulation and Mirror Therapy for Foot Clearance Among Patients With Sub-acute Stroke

This study aims to evaluate the effectiveness of two rehabilitation techniques- Functional Electrical Stimulation (FES) and Mirror Therapy (MT)-in improving motor recovery among stroke survivors. Stroke often results in long-term impairments, particularly in foot clearance, which is critical for daily activities. Although current rehabilitation strategies help, more effective solutions are needed to enhance recovery. Participants, aged 18- 85 years old with subacute stroke and foot clearance impairments, will be randomized into two groups: Group A will receive functional electrical stimulation (FES) with routine physical therapy; and Group B will receive mirror therapy (MT) with routine physical therapy. The interventions will take place three times a week for 4 weeks, and participants will undergo motor function assessments, including the Fugl-Meyer Assessment and Functional Independence Measure, before and after the intervention. The study will compare the effects of each intervention on motor recovery, specifically focusing on tibialis anterior function and motor control. The findings could lead to improved rehabilitation protocols, offering stroke survivors better therapeutic options and enhancing their quality of life.

Motor Relearning Program Combined With Neck Stabilization Exercises in Subacute Stroke

Stroke is a neurological event that leads to significant motor and functional impairments due to disruption of cerebral blood flow. The subacute phase, typically ranging from day of attack up to three months post-stroke, is a critical window for neuroplasticity and functional recovery. The proposed study will find out the effects of motor relearning program combined with neck stabilization exercises for health-related quality of life, sensorimotor function and upper extremity functionality.
