Abstract

This thesis documents the studies and analyses conducted as part of a research project whose principal aim was to evaluate the role of body schema in the development of adolescent idiopathic scoliosis (AIS). There were three main research questions:

1. do adolescents with AIS differ from non-scoliotic adolescents with regard to mechanisms that are thought to underpin body schema?

2. in adolescents with AIS, is there any relationship between the mechanisms thought to underpin body schema and the magnitude of spinal deformity?

3. is there any relationship between changes in body schema and progression of the spinal deformity in AIS over time?

To answer these questions, a systematic review of neurophysiological deficits in AIS and a case-control study involving patients with AIS and non-scoliotic controls was performed along with a series of correlational and longitudinal analyses. Fifty-eight participants with AIS (cases) were recruited along with 197 age and sex-matched control participants from schools in Warwickshire, Oxfordshire, Leicestershire and Coventry. Measures of body schema as well as other self-report measures were collected at baseline for both groups. Cases were followed up at 6 and 12 months. Imaging data of spinal deformity was also collected for case participants.

The results of the systematic review and case-control analysis indicated that people with AIS did not differ significantly from non-scoliotic controls with regard to measures of body schema. The correlational and longitudinal analyses confirmed the lack of association between these two sets of parameters with no relationship between the magnitude of spinal deformity and body schema over a period of 12 months.

Secondary analyses did reveal differences between case and control participants with regard to perceived spinal deformity, pain, self-image and, to a lesser extent, function. Correlational and longitudinal analyses revealed that these differences were not related to the magnitude of spinal deformity and that perceptions of spinal deformity may be more important than the actual bony changes themselves.
