Introduction: Scoliosis is lateral curvature of the spine greater than 100 accompanied by vertebral rotation. The prime risk factors for curve progression are a large curve magnitude, skeletal immaturity and female gender. The curve progression can be recorded by measuring the curve magnitude using the Cobb method on radiographs.
Aim: To assess the effect of task oriented exercises based on ergonomics on Cobbâ€™s angle and pulmonary functions on one year outcome of Adolescent Idiopathic Scoliosis(AIS) (defined as curves < 150 for thoracolumbar region and < 200 for thoracic region).
Materials and Methods: A total of 36 patients were enrolled in the study and 18 patients in each group (experimental and control group) were allocated randomly. The subjects in control group underwent spinal strengthening exercises, active self-correction and breathing exercises, whereas subjects in the experimental group followed task oriented exercises based on ergonomics in addition to exercises for conventional group for one year. Chi square test was used to compare the categorical/dichotomous variables between the groups. Unpaired t-test was used to compare continuous variables between the groups at pre and post intervention. Paired t-test was used to compare the changes in continuous variables from pre to post intervention within the group.
Results: FVC was found to be significantly (p=0.001) higher in experimental group (2.68Â±0.37) than control group (2.20Â±0.41) at post-intervention. FEV1 (p=0.01) and VC (p=0.002) were also found to be significantly higher in experimental group compared to control group at postintervention. Also, there was significant (p=0.001) mean reduction in Cobbâ€™s angle from pre to post intervention in both the groups being higher in Experimental group than control group.
Conclusion: The task oriented exercise protocol benefited patients with AIS which had a significant improvement of their pulmonary functions and Cobbâ€™s angle.
