Shoulder Musculoskeletal Disorders

The development of an Arabic questionnaire to assess acceptance of VR in upper limb rehabilitation would include adapting Technology Acceptance Model TAM, followed by panel review for content validity. Subsequently, a pilot testing with a sample of patients that would be followed by face validity testing then administering the revised instrument to a larger sample for comprehensive psychometric evaluation. Reliability would be established through internal consistency and test-retest parameters, while validity includes construct validation via factor analysis and criterion comparisons with related scales

Goal: The clinical investigation involves the evaluation of the usability level of the VR system, sense of presence, and co-presence during the execution of various rehabilitation exercises through specific questionnaires. Participant Population: The study will enroll 50 patients with shoulder musculoskeletal disorders will be enrolled Main Questions: * How does the integration of Virtual Reality (VR) in rehabilitation programs impact the usability of the system for patients with shoulder musculoskeletal disorders? * To what extent does the sense of presence experienced by patients using VR systems influence their motivation and adherence to rehabilitation exercises? * How do patients with shoulder musculoskeletal disorders perceive the co-presence in VR rehabilitation scenarios, and how does it affect their overall treatment experience? Participant Tasks: * Shoulder Physical Examination * Instructions to the patient on exercises to be performed using Oculus and selection of customizable settings on the VR app * Execution of the protocol developed for shoulder rehabilitation in a virtual environment * Evaluation of the usability of the VR system, sense of presence, and co-presence through different validated scales
