• Conditions: Healthy; Stroke

• Registration Number: NCT07039136
• Lead Sponsor: Abant Izzet Baysal University

Brief Summary

Mirror therapy has been shown to support motor recovery by stimulating neural mechanisms through visual feedback. Recent technological advancements, particularly in virtual reality (VR), have enabled the development of more immersive and interactive rehabilitation tools. This study focuses on evaluating the usability of a novel, Leap Motion-based Virtual Reality Mirror Therapy (VRMT) system designed to enhance upper limb rehabilitation in stroke patients by combining traditional mirror therapy principles with engaging, gamified digital environments.

Detailed Description

The VRMT system was developed to provide a low-cost, sensor-based rehabilitation tool that enables stroke survivors to engage in interactive upper limb exercises. Utilizing the Leap Motion sensor for real-time hand tracking, the system projects mirrored movements of the unaffected limb onto a virtual representation of the affected limb, reinforcing motor learning and neuroplasticity. The system includes multiple gamified tasks that simulate functional hand and arm movements within a virtual environment. Participants with subacute or chronic stroke used the system across several sessions, after which usability and user experience were assessed using standardized tools such as the System Usability Scale (SUS) and User Experience Questionnaire (UEQ). This approach allows for detailed feedback on comfort, satisfaction, interaction quality, and perceived effectiveness, contributing to future development and clinical integration of VR-based rehabilitation technologies.The aim of this study is to evaluate the usability, acceptability, and user experience of a Leap Motion-based Virtual Reality Mirror Therapy (VRMT) system designed to support upper limb rehabilitation in individuals with stroke. By integrating traditional mirror therapy principles with immersive virtual environments, the study seeks to determine the feasibility of using this system in clinical and home-based rehabilitation settings.

Primary Outcome Measures

Name	Time	Method
Simulator Sickness Questionnaire	One hour	"The SSQ evaluates 16 symptoms-including eye strain, nausea, sweating, and headache-using a four-point scale (none, mild, moderate, and severe). These symptoms are categorized into three overlapping subscales: nausea, oculomotor discomfort, and disorientation. Higher scores within each subscale reflect more intense experiences of simulator sickness. In military aviation contexts, a total SSQ score above 20 is typically interpreted as indicative of poor tolerance to simulation exposure. The total score generally ranges from 0 to 30, with higher scores indicating lower tolerance to simulated environments.

Secondary Outcome Measures

Name	Time	Method
Presence Questionnaire	One hour	The PQ comprises four subscales: Involvement, Sensory Fidelity, Adaptation/Immersion, and Interface Quality. Participants respond to each item using a 5-phe total score generally ranges from 0 to 30, with higher scores indicating lower tolerance to simulated environments.oint Likert scale, reflecting their perceived experience in the virtual environment. The total score generally ranges from 24 to 168, with higher scores indicating better presence feeling in simulated environments.

The total score generally ranges from 0 to 27, with higher scores indicates higher motion sickness feeling in simulated environments.
System Usability Scale	One hour	The System Usability Scale (SUS) is a 10-item instrument developed to rapidly assess the usability of various technological systems, including websites, software, hardware, and mobile devices. It employs a 5-point Likert scale and focuses primarily on user-perceived usability.A score of 68 is considered the average benchmark, with scores above this value indicating above-average usability, and scores below 68 reflecting below-average usability. Systems receiving the highest usability ratings fall into the A+ category, corresponding to the 96th to 100th percentile range.The total score generally ranges from 0 to 100, with higher scores indicates better usability..
