 The study aimed to evaluate the effectiveness of app-based relaxation exercises in reducing chronic neck pain compared to usual care alone. The results showed that while both groups experienced a decrease in neck pain intensity over three months, there was no statistically significant difference between the intervention and control groups. Additionally, adherence to the exercise program was low, with only 40% of participants continuing to practice the exercises at week 12. The study suggests that future app-based relaxation interventions should incorporate behavior change techniques based on recent scientific findings.
