About this study

Official title: Effects of Augmented Reality and Virtual Reality-Assisted Gait Training on Balance and Walking in Individuals With Stroke

This randomized controlled trial aims to compare the effects of augmented reality (AR) and virtual reality (VR)-assisted treadmill gait training on balance and walking in individuals with stroke, within the framework of the International Classification of Functioning, Disability and Health (ICF). A total of 66 post-stroke patients will be randomly assigned to three groups: (1) VR group receiving gait training via C-Mill VR applications in addition to conventional physiotherapy, (2) AR group receiving gait training via C-Mill AR applications in addition to conventional physiotherapy, and (3) control group receiving a home exercise program alongside conventional physiotherapy. Participants will train for 45 minutes per day, five days a week, for three weeks. Outcome measures will include clinical, functional, cognitive, and spatiotemporal gait parameters to evaluate changes in balance and walking ability before and after the intervention.

Read the detailed description

This prospective, randomized controlled study aims to compare the effects of augmented reality (AR) and virtual reality (VR)-assisted treadmill gait training on balance and walking in individuals with stroke, and to contribute to the literature through a comprehensive analysis within the International Classification of Functioning, Disability and Health (ICF) framework. Stroke is a leading cause of long-term disability and care burden, with nearly one-third of acute stroke survivors unable to walk three months after onset. Improving walking ability is a central goal of stroke rehabilitation. There is increasing evidence that high-intensity, task-specific, and repetitive training can enhance functional recovery. Treadmill training enables intensive, repetitive practice of complex gait patterns and has been shown to improve walking speed and distance in stroke survivors. Technological advances have introduced immersive tools such as VR and AR systems into rehabilitation, providing engaging and interactive environments that enhance motor learning and patient motivation.

The C-Mill VR+ system (Motek, Netherlands) is a treadmill equipped with both AR and VR applications, offering visual-auditory feedback, safety harnesses, and force sensors. Though studies suggest C-Mill training improves gait and reduces fall risk in geriatric and Parkinson's disease populations, comprehensive randomized controlled trials comparing AR- and VR-supported treadmill training in stroke rehabilitation are lacking.

This study will enroll 66 individuals with stroke undergoing inpatient rehabilitation at the Virtual Reality Laboratory of Ankara Bilkent City Hospital. Inclusion criteria include diagnosis of hemiplegia (ICD-10 code G81), age 18 or older, and ability to walk with or without assistance (Functional Ambulation Classification ≥ 2). Exclusion criteria include aphasia, MoCA score <10, additional neurological/orthopedic problems, recurrent stroke, or a Modified Ashworth Scale (MAS) score of 3-4 in the lower extremities. Participants will be randomly assigned to one of three groups: (1) VR group-C-Mill VR treadmill training with Nature Island, Italian Apps, and Soccer applications; (2) AR group-C-Mill AR training using Stepping Stones, Reactive Stones, Obstacles, Speed Adjustment, Slalom, Tandem, and Monster Game applications; (3) Control group-home-based walking exercises (flat ground, variable step length, obstacles, and speed) in addition to standard physiotherapy. All groups will continue routine physiotherapy and receive 45-minute training sessions, five days a week for three weeks.

Outcome measures assessed pre- and post-intervention include the Timed Up and Go Test, Fugl-Meyer Lower Extremity Motor Assessment, Modified Ashworth Scale, Activities-specific Balance Confidence Scale, Berg Balance Scale, Functional Ambulation Classification, Trunk Impairment Scale, Stroke Impact Scale (3.0), Stroke-Specific Quality of Life Scale, Montreal Cognitive Assessment (MoCA), and spatiotemporal gait analysis via the C-Mill VR+ system. Gait analysis will record step lengths, stance and swing phases, and double support percentages for both paretic and non-paretic limbs at self-selected and fixed speeds.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Timed Up and Go (TUG) Test

    To perform the test, the patient stands up from a chair approximately 46 cm in height, walks at a comfortable and safe pace to a marked target three meters away, turns around the target, and returns to sit back down on the chair. To ensure familiarity with the procedure, the patient performs one trial without timing. If needed, the patient may use their usual walking aid (e.g., cane or walker). A shorter completion time indicates better performance.

    Measured: baseline and after 3 weeks

  2. Berg Balance Scale (BBS)

    The scale consists of 14 items and assesses the patient's ability to maintain balance (either static or during various functional movements) over a specific period of time. Each item is scored on a scale from 0 to 4:

    0 points: Unable to complete the task. 4 points: Completes the task independently. The maximum total score is 56. A score of 0-20 indicates poor balance, 21-40 indicates acceptable balance, and 41-56 indicates good balance.

    Measured: baseline and after 3 weeks

  3. Gait Analsis

    Spatio-temporal gait analysis will be performed using the C-Mill VR+ device. As a result of this measurement, step lengths, stance phases (%), swing phases (%), and double support phases (%) of the paretic and non-paretic limbs will be recorded. Gait analysis will be conducted in two separate assessments: at the participant's self-selected comfortable walking speed and at a fixed speed of 1 km/h. The gait analysis will begin after a 2-minute warm-up period, and data will be collected for the following 2 minutes. A rest period of at least 5 minutes will be provided between the two assessments.

    Measured: baseline and after 3 weeks

Secondary outcomes (6)
  1. Fugl-Meyer Motor Assessment Lower Extremity (FMA-LE)

    The FMA is a widely used, valid, and reliable test for evaluating motor impairments of the paretic upper and lower extremities in stroke patients. Each item on the scale is scored as follows: 0 = unable to perform, 1 = performs partially, and 2 = performs fully. Higher scores indicate better motor function. In this study, the 34-point lower extremity section of the scale will be used.

    Measured: baseline and after 3 weeks

  2. Activities-specific Balance Confidence (ABC) Scale

    The ABC Scale is a 16-item self-assessment questionnaire that asks individuals to rate their confidence in maintaining balance during specific ambulatory activities on a numerical scale from 0 to 100. A score of 0 represents no confidence at all, while a score of 100 represents complete confidence in performing the activity. Each participant's total ABC score is calculated by summing the scores for each item and then dividing by the number of items. Botner et al. reported that the scale can be used to assess fear of falling in individuals with stroke. Myers and colleagues suggested that ABC scores below 50 indicate low physical function, scores between 50 and 80 indicate moderate physical function, and scores above 80 indicate high functionality among physically active older adults.

    Measured: baseline and after 3 weeks

  3. Functional Ambulation Category (FAC)

    The FAC is a valid and reliable scale used in patients with post-stroke hemiparesis that classifies walking ability into six levels based on the amount of physical assistance required. A score of 0 indicates that the patient needs assistance from two people to walk, while a score of 5 represents independent walking on all surfaces including stairs.

    Measured: baseline and after 3 weeks

  4. Trunk Impairment Scale (TIS)

    The scale was developed to assess trunk function after stroke. It consists of three sections: static sitting balance, dynamic sitting balance, and coordination. Due to a ceiling effect in the static sitting balance section, a revised version was developed in 2010 that excludes this section. This new version is recommended for patients with mild to moderate impairment and those in the chronic phase.

    Measured: baseline and after 3 weeks

  5. Stroke Impact Scale (SIS) Version 3.0

    The SIS is a comprehensive health status measure specifically designed for stroke. It consists of 8 domains and 59 items. Each item is rated on a scale from 1 to 5. For items 3f, 3h, and 3i in domain 3, reverse scoring is applied using the formula (6 - the marked score). A new domain has been added to assess the patient's overall perception of recovery, where the patient rates their recovery on a scale from 0 to 100. The score for each subdomain is calculated using the formula:

    Subdomain Score = ((Mean Item Score - 1) / 4) × 100

    Measured: baseline and after 3 weeks

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

    The scale consists of 12 domains-Thinking, Personality, Mood, Family Roles, Social Roles, Energy, Self-Care, Vision, Language, Mobility, Work/Productivity, and Upper Extremity Function-and includes a total of 49 items. Each item is scored using a 5-point Likert scale based on the patient's experience during the past week. The overall quality of life score is the sum of the scores from all subdomains. Higher scores indicate better quality of life. Subdomains can also be analyzed independently to identify specific areas of difficulty.

    Measured: baseline and after 3 weeks
