Virtual Reality-Based Hypnotherapy for Pain, Sleep, and Mood in Spinal Cord Injury

The goal of this clinical trial is to learn whether virtual reality (VR)-based hypnotherapy, added to conventional physiotherapy, improves pain, sleep, mood, and quality of life in adults with chronic spinal cord injury. The main questions it aims to answer are: * Does VR-based hypnotherapy added to physiotherapy reduce pain intensity more than physiotherapy alone? * Does it improve neuropathic pain, sleep quality, anxiety and depression, spasticity, and quality of life? Researchers will compare participants who receive VR-based hypnotherapy in addition to physiotherapy with participants who receive physiotherapy alone. Participants will: * Receive a standard physiotherapy and rehabilitation program 5 days a week for 2 weeks (10 sessions). * If assigned to the VR group, also receive an approximately 20-minute VR-based hypnotherapy session after each physiotherapy session, using a VR headset and headphones. * Complete assessments at the start of the study, at the end of the 2-week treatment period, and 2 weeks after treatment ends.

Inclusion Criteria: * Age between 18 and 65 years * Diagnosis of spinal cord injury * Injury duration longer than 3 months * Mini-Mental State Examination (MMSE) score above 24 * Willingness to participate and provision of written informed consent Exclusion Criteria: * Injury duration shorter than 3 months * Significant change in analgesic treatment within the last 3 months * Visual or hearing impairment * Epilepsy * Severe psychiatric illness (psychosis, severe major depression, or bipolar disorder in the acute phase) * Pregnancy
