Abstract
The purpose of the study was to compare the effect of low-level laser therapy (LLLT), ultrasound therapy (US), and strengthening and stretching exercise in children diagnosed with cervical straightening caused by long-term use of electronic devices. A total of 60 patients from 12 to 18 years of both gender diagnosed with straight neck syndrome which is losing the normal C shape of cervical vertebrae. Patients were randomized into three groups. In group A, patients received LLLT plus exercise, while in group B, they received US plus exercise, and group C received exercise. In group A and B, Cobb angle and VAS showed a significant improvement (more significant in group A) with P < 0.001, while in group C P = 0.006. LLLT, US, and exercise improved the cervical straight curve, and reduced pain with maximum effect was done by LLLT.
