Gaziler Physical Medicine and Rehabilitation Education and Research Hospital30 enrolled

Overview

The aim of this study is to compare the effects of body weight-supported gait training that includes virtual reality-assisted dual-task applications with body weight-supported forward and backward gait training on functional capacity, gait parameters (such as step length, gait speed, and balance), cognitive functions and psychological status in patients with stroke. The findings of this study are expected to contribute to the development of more effective rehabilitation strategies for improving mobility in patients with stroke

Stroke is a leading cause of disability worldwide and often results in motor, balance, and cognitive impairments that negatively affect functional independence and quality of life. Walking limitations are among the most common consequences after stroke and represent a major barrier to community participation. Therefore, improving gait performance and functional mobility is a primary goal of stroke rehabilitation. Body weight-supported gait training is widely used to improve walking ability in individuals with impaired balance and reduced motor function. In recent years, rehabilitation technologies such as virtual reality-assisted gait training have been increasingly incorporated into clinical practice. Virtual reality may enhance patient engagement and promote both motor and cognitive recovery by providing interactive environments and increasing task demands. Backward walking training has also gained attention as an alternative rehabilitation approach. Compared to forward walking, backward walking requires greater postural control and cognitive processing, similar to dual-task training, and may contribute to improvements in balance and gait performance. However, there is limited evidence directly comparing virtual reality-assisted dual-task gait training with backward walking training in patients with stroke. This study aims to compare the effects of body weight-supported virtual reality-assisted dual-task gait training and body weight-supported forward and backward gait training on functional capacity, gait parameters, cognitive functions, and psychological status in patients with stroke. The findings of this study are expected to contribute to the development of more effective rehabilitation strategies for improving mobility and functional outcomes in stroke rehabilitation.

Outcomes

Primary Outcomes

10-Meter Walk Test

A measure used to assess patients' ambulation. During the test, the patient walks at a comfortable walking speed between two markers placed 10 meters apart, and the time required to complete the distance is recorded.

Time frame: At baseline and after 6 weeks of intervention.

Secondary Outcomes

6-Minute Walk Test (6MWT)

A submaximal exercise test commonly used to assess functional capacity and response to treatment. During the test, participants are instructed to walk as far as possible within six minutes. The total distance walked is recorded as an indicator of cardiopulmonary capacity and exercise tolerance.

Time frame: At baseline and after 6 weeks of intervention

Fugl-Meyer Assessment - Lower Extremity Motor Subscale

A standardized assessment used to evaluate sensorimotor impairment in individuals with stroke. The lower extremity motor subscale measures motor recovery and functional movement of the lower limb following stroke.

Time frame: At baseline and after 6 weeks of intervention

Functional Independence Measure (FIM)

A widely used assessment tool for evaluating functional abilities in individuals undergoing rehabilitation. The scale assesses both motor and cognitive domains, including self-care, sphincter control, transfers, mobility, communication, and social interaction.

Time frame: At baseline and after 6 weeks of intervention.

Berg Balance Scale (BBS)

A widely used clinical test for assessing static and dynamic balance abilities. The test consists of a series of functional balance tasks, each scored on a scale from 0 (unable) to 4 (independent), with the total score representing overall balance performance.

Time frame: At baseline and after 6 weeks of intervention.

Montreal Cognitive Assessment (MoCA)

A brief cognitive screening tool used to assess cognitive functions, including memory, attention, language, visuospatial abilities, executive functions, calculation, and orientation. The test is scored on a 30-point scale, with higher scores indicating better cognitive performance.

Time frame: At baseline and after 6 weeks of intervention.

Stroke-Specific Quality of Life Scale (SS-QOL)

A standardized measure used to assess health-related quality of life in individuals with stroke, covering physical, emotional, and social domains affected by the condition.

Time frame: At baseline and after 6 weeks of intervention.

Hospital Anxiety and Depression Scale (HADS)

A 14-item self-report questionnaire designed to assess the presence and severity of anxiety and depression symptoms in clinical populations.

Time frame: At baseline and after 6 weeks of intervention.

Foot Rotation

Gait analysis will be performed using the Zebris RehaWalk® system. Foot rotation (foot progression angle) quantifies the angular deviation of the foot relative to the direction of walking, measured in degrees.

Time frame: At baseline and after 6 weeks of intervention.

Step Width

Gait analysis will be performed using the Zebris RehaWalk® system. Step width measures the mediolateral distance between the heel centers of consecutive footfalls during walking.

Time frame: At baseline and after 6 weeks of intervention.

Step Length

Gait analysis will be performed using the Zebris RehaWalk® system. Step length measures the anteroposterior distance between the heel contact point of one foot and the heel contact point of the contralateral foot during walking.

Time frame: At baseline and after 6 weeks of intervention.

Stance Phase

Gait analysis will be performed using the Zebris RehaWalk® system. Stance phase represents the percentage of the gait cycle during which the foot remains in contact with the ground.

Time frame: At baseline and after 6 weeks of intervention.

Swing Phase

Gait analysis will be performed using the Zebris RehaWalk® system. Swing phase represents the percentage of the gait cycle during which the foot is off the ground.

Time frame: At baseline and after 6 weeks of intervention.

Double Stance

Gait analysis will be performed using the Zebris RehaWalk® system. Double stance represents the percentage of the gait cycle during which both feet are simultaneously in contact with the ground.

Time frame: At baseline and after 6 weeks of intervention.

Gait Velocity

Gait analysis will be performed using the Zebris RehaWalk® system. Gait velocity measures the distance covered per unit time during walking, with reduced speed being one of the most sensitive indicators of hemiparetic gait impairment post-stroke.

Time frame: At baseline and after 6 weeks of intervention.

Cadence

Gait analysis will be performed using the Zebris RehaWalk® system. Cadence measures the number of steps taken per minute during walking, reflecting the temporal coordination of the gait cycle

Time frame: At baseline and after 6 weeks of intervention.

Maximum Plantar Pressure

Gait analysis will be performed using the Zebris RehaWalk® system. Maximum plantar pressure measures the peak pressure exerted on the foot sole during the stance phase of gait.

Time frame: At baseline and after 6 weeks of intervention.

Center of Pressure, Lateral Symmetry

Gait analysis will be performed using the Zebris RehaWalk® system. Center of Pressure (COP) Lateral Symmetry measures the mediolateral displacement of the center of pressure between the paretic and non-paretic limbs during walking, reported in millimeters.

Time frame: At baseline and after 6 weeks of intervention.
