The primary objective of this clinical trial is to investigate the effect of a block of four specific virtual reality (VR) exercises on upper limb function, pain, kinesiophobia, and pain catastrophizing in individuals with rotator cuff-related shoulder pain (RCRSP). The secondary objective is to examine participants' tolerability of different VR interventions.
Study Procedures:
Participants will:
* Attend a face-to-face assessment to confirm eligibility and receive a standardized pain neurophysiology education session (week 0).
* Visit the clinic once weekly for four weeks to undergo the VR interventions and review pain education concepts (Weeks 5 to 8).
* Complete online questionnaires evaluating upper limb function, kinesiophobia, pain, sense of presence, and cybersickness.
Interventions
Four VR interventions will be tested:
* Unimanual distraction task with normal visual feedback
* Bimanual distraction task with normal visual feedback
* Unimanual reaching task with augmented visual feedback
* Unimanual reaching task with diminished visual feedback
Findings will guide clinicians in selecting the most effective VR interventions for shoulder impairment and assess the feasibility of implementing VR in a private physiotherapy clinic for individuals with RCRSP.
