Background: Non-specific neck pain (NSNP) is a common musculoskeletal condition in young adults, frequently associated with poor posture, psychosocial stress, and sedentary behaviour, and continuous screen time on smartphones. Successful rehabilitation methods, particularly telerehabilitation follow-up, have gained prominence due to their accessibility and flexibility. Objective: To compare the efficacy of telerehabilitation follow-up using smartphones vs. no follow-up intervention in young adults recovering from NSNP after initial treatment, with the Neck Disability Index (NDI) as the main outcome measure.

Methods: 20 young adults with NSNP were randomly assigned to two equal groups (Group A and Group B; n=10 each). All subjects filled out the NDI questionnaire at three points 1. Pre-treatment (baseline) 2. Post initial (surgical/clinical) treatment 3. Follow-up post –up post- one week of telerehabilitation. Group A had a one-week telerehabilitation follow-up program consisting of supervised neck exercises, posture correction, and ergonomic counselling through video call on smartphones. Group B received no additional intervention following their first treatment. NDI scores were compared to identify functional changes and symptom decrease between and within groups.

Results: Both groups improved following initial treatment. Group A, however, had a significantly higher decrease in NDI scores following the telerehabilitation phase (p < 0.05) than Group B. Group A participants reported improved neck function, decreased pain, and enhanced performance of daily activities. These findings are in line with current literature attesting to the advantages of organized, home-based physiotherapy interventions.

Conclusion: Telerehabilitation follow-up using video call on smartphones considerably improves functional recovery and decreases neck disability in young adults with non-specific neck pain. Adding telerehabilitation physiotherapy to routine post-treatment practices can enhance outcomes and accessibility, particularly for technology-friendly and time-conscious youth populations.
