Purpose: Visual and proprioceptive cues are important for body orientation to maintain correct posture. This study investigated the effects of exercise training on subjective visual, postural, and haptic perception of verticality in patients with scoliosis. Subjects and Methods: Thirty-two female adolescents with moderate idiopathic scoliosis were randomly allocated to Core Stabilization Exercise (CSE), Body Awareness, or Traditional Exercise (TE) groups. Each group completed a 1-hour supervised program, two days per week for 10weeks while continuing to wear spinal braces. Perceptual visual, postural, and haptic estimates were assessed before and after treatment. Results: Subjective visual vertical perception only improved in the awareness group. Subjective visual horizontal perception, postural vertical perception, total postural perception scores, total haptic perception scores, and haptic perception 45 degrees to the right were significantly improved in the stabilization and awareness groups. For the 60 degrees right and 60 degrees left postural perception parameters, as well as the 45 degrees left haptic perception parameters, perception improved only in the stabilization group. No improvement was observed in the traditional group. Conclusion: Improvements in visual, postural, and haptic verticality perception within the stabilization exercise training and Basic Body Awareness group treatment suggest the addition of these exercise methods for the treatment of idiopathic scoliosis to improve internal body orientation.
