Background: This study aimed at investigating the effects of an online corrective exercise intervention on correcting forward head and kyphosis as well as reducing feelings of fatigue and pain in adolescents. Methods: The present study enjoyed a causal-comparative design. The participants included ۴۰ females aged ۱۳-۱۵ years. Upper cross syndrome was measured by the use of Image J software and Spinal Mouse. Feeling of fatigue and pain were assessed through questionnaires. During correctional training, the intervention group performed corrective exercises for eight weeks, three sessions per week, and each session lasting ۳۰-۴۵ minutes within the WhatsApp application. Results: Body mass index (mean ۲۲.۸۶) in female adolescents was in the normal range (between ۱۸.۵ and ۲۵), although it was close to its high level. The results showed that an online training course improved and corrected the condition of forward head (P=۰.۰۰۰) and kyphosis (P=۰.۰۰۰) in female adolescents. Furthermore, this training period has significantly reduced the feeling of fatigue (P=۰.۰۰۰) and pain (P=۰.۰۰۰). In addition, the results of the follow-up test revealed that the positive effects of an online correctional training period remained constant over time (P=۰.۰۰۰). Conclusion: Corrective movements are effective in strengthen the muscles of the neck and back, and stretching the anterior muscles of the neck and chest in people with anterior head and kyphosis; while improving the condition of the head and kyphosis in adolescents, they can also reduce the feelings of fatigue and pain. Moreover, practicing methods for correcting abnormalities can be used online and virtually.
