Camptocormia is a disabling pathology of the axial system that
debilitates patients in their daily life. To date, there have been no studies
evaluating the impact of camptocormia on walking performance. This study presents
a new method for assessing sagittal posture under walking conditions in patients
with camptocormia. DESIGN: The severity of camptocormia was evaluated by
measuring sagittal inclination, represented indirectly by the horizontal distance
between the C7 and S1 markers (C7 sagittal arrow; C7-SAR). Sagittal inclination
was measured under various behavioural conditions using clinical, radiological
and kinematic approaches. PATIENTS: Forty-three patients were included in the
study (17 with Parkinson's disease and 26 with idiopathic camptocormia). RESULTS:
Under static conditions, C7-SAR could be assessed using different methods. During
walking, there was a dramatic increase in C7-SAR values. Correlation analysis
revealed a relationship between functional impairment and dynamic C7-SAR values,
but not with radiological C7-SAR values. PATIENTS with Parkinson's disease
behaved differently from idiopathic patients, suggesting the involvement of
different underlying physiopathological mechanisms. CONCLUSION: Monitoring
sagittal inclination during walking is more accurate than radiological
measurements to determinine the detrimental effects of camptocormia and its
consequences for quality of life.
