They were allocated randomly into three groups: Group A consists of 20 patients received a multiwave locked system laser, group B consists of 20 patients received Pilates exercises and group C consists of 20 patients received a multiwave locked system laser and Pilates exercises. Patients with a history of tumors, ovariectomy, heart disease, renal failure, disc prolapse, or any trauma to the back area were excluded from the study. All patients who participated in the current study did not intake any medications to accelerate bone density like vitamin D or calcium. The randomization method was applied by asking each patient to choose a piece of paper that the (A), (B), or (C) letter was written. (A) considered the LLLT group, (B) considered the Pilates exercise group, while (C) considered the LLLT and Pilates exercises group. Both patients, the examiner, and therapist were blinded from the selection process.
