VR-based optokinetic stimulation added to neuromuscular training in basketball players

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This randomized, three-arm trial assigns 42 licensed basketball players (16-35 years old) to usual training, neuromuscular training plus usual training, or VR-based optokinetic stimulation followed by neuromuscular training plus usual training for six weeks. The primary outcome is the maximum knee flexion during landing from a drop vertical jump, measured with a force platform and motion capture. The VR intervention precedes each neuromuscular training session and gradually increases visual speed and complexity to probe sensory integration. Standard exercises include strength, balance, proximal control, and plyometrics, with safety monitoring for VR-related symptoms. The goal is to see if the VR component provides added benefits beyond neuromuscular training alone.

Why it matters

Who can join: the full rules

Inclusion Criteria:

* Aged 16-35 years.
* Body mass index of 18.5-25 kg/m².
* Landing Error Scoring System (LESS) score of at least 6.
* A licensed basketball player at a club actively competing at the second-league level.
* At least three years of regular basketball playing and training experience.
* Participation in regular basketball training at least three days per week, with each session lasting at least one hour.
* A System Usability Scale (SUS) classification of A+ for the virtual reality system, corresponding to the 96th-100th percentile range.
* No trunk or lower-extremity injury within the previous six months.
* Willingness to provide written informed consent. For participants younger than 18 years, parental or legal guardian consent and participant assent will also be obtained.

Exclusion Criteria:

* More than two weeks away from sport due to a lower-extremity injury within the previous six months.
* A history of lower-extremity fracture, dislocation, or surgery resulting in functional limitations.
* A congenital or acquired musculoskeletal abnormality that may affect lower-extremity biomechanics.
* Inability to perform the study tasks safely because of a visual, auditory, vestibular, or neurological disorder.
* A history of migraine, epilepsy, severe motion sickness, or concussion within the previous six months.
* Participation in vestibular rehabilitation or a structured neuromuscular injury-prevention program within the previous six months.
* Cybersickness symptoms severe enough to prevent tolerance of the virtual reality intervention.
