OBJECTIVE: 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
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
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.
