This study aims to investigate the effect of virtual reality (VR) on upper extremity functions, reaction time, and proprioception in healthy individuals. A randomized crossover design was used, where 26 participants performed a task-oriented movement in both real and virtual environments. Each participant completed a single-session intervention using the Oculus Quest 2 VR system. The study measured Joint Position Sense (JPS), Reaction Time (RT), and Gross Manual Dexterity using standard clinical tests before and after the intervention. The results will help understand how VR-based task-oriented movements influence upper extremity function and whether VR can be effectively used in rehabilitation and sports science applications.
This description provides a summary of the key elements of the study protocol, focusing on the design, interventions, and general approach to evaluation. It does not include the full protocol document or detailed assessment procedures, which are available upon request.
This study is a randomized cross-over trial designed to investigate the acute effects of a task-oriented movement-based virtual reality (VR) application on upper extremity functions in healthy individuals. The primary aim is to evaluate the impact of VR-supported movement exercises on joint position sense (JPS), reaction time (RT), and gross manual dexterity.
The research involves 26 healthy participants who were randomly assigned to two intervention sequences:
Real Performance first (f-RP) group: Participants performed task-oriented movements in a real environment on the first day, followed by a VR-based task-oriented movement session on the second day.
Virtual Reality first (f-VR) group: Participants performed VR-based task-oriented movements on the first day, followed by a real environment session on the second day.
Each intervention lasted 10 minutes and included a task-oriented ball-throwing activity, where participants used repetitive wrist and upper limb movements to throw balls into a target pool placed 2 meters away. The VR intervention was delivered using the Oculus Quest 2 head-mounted display, with real-time visual, auditory, and tactile feedback integrated into the application. The real-world intervention matched the VR setup as closely as possible, including chair position, distance to the target, and ball size.
Assessments were conducted immediately before and after each intervention to observe acute effects. The primary focus was on changes in upper extremity functions and neuromuscular responses following task-oriented movements in VR and real environments.
Data were analyzed for within-group and between-group differences, as well as potential carryover and period effects, using parametric statistical methods appropriate for cross-over trials. The results indicated that VR-based task-oriented applications acutely enhanced reaction time and supported hand functions in healthy individuals. JPS measures remained stable across both intervention types, suggesting that VR-created movement perception can closely resemble real-world joint positioning.
These findings contribute to understanding the short-term effects of VR applications on upper extremity functions and support the potential for VR-based interventions in rehabilitation and performance enhancement.

Exclusion Criteria:
Participants first performed the task-oriented movement in a real environment. On the following day, they completed the same movement using a virtual reality (VR) system (Oculus Quest 2). Joint Position Sense, Reaction Time, and Gross Manual Dexterity were measured before and after each intervention.
Behavioral: Real Performance Task-Oriented Movement
Participants first performed the task-oriented movement using a virtual reality (VR) system (Oculus Quest 2). On the following day, they completed the same movement in a real environment. Joint Position Sense, Reaction Time, and Gross Manual Dexterity were measured before and after each intervention.
Behavioral: Virtual Reality Task-Oriented Movement
Participants performed a task-oriented movement in a real environment by throwing balls into a physical pool for 10 minutes. The movement was designed to engage upper extremity function.
Participants performed a task-oriented movement in a virtual environment using the Oculus Quest 2 VR system for 10 minutes. The task involved throwing virtual balls into a virtual pool with real-time feedback.
Reaction Time (RT) in milliseconds
Reaction time was measured using a mobile application ("Reaction Time Test" app) before and after the intervention. Participants tapped the screen as quickly as possible when a visual stimulus appeared. The average reaction time (in milliseconds) over 25 trials was recorded.
Time frame: Day 1 (immediately after intervention) and Day 2 (immediately after intervention)
Joint Position Sense (JPS) measured in degrees
Joint position sense was evaluated using a universal goniometer for both shoulder and wrist proprioception. Participants were asked to reproduce specific joint angles without visual feedback, and the absolute angular error (in degrees) was recorded.
Time frame: Day 1 (immediately after intervention) and Day 2 (immediately after intervention)
Plan to share: Yes — De-identified participant data (reaction time, joint position sense, and Box and Block Test scores) will be shared upon reasonable request. Data will be available after study completion for researchers conducting related studies. Requests should be submitted via email to z_pancar@hotmail.com
