Rien de vraiment nouveau.. mais ça confirme ce que l’on savait déjà ! C’est-à-dire que nonobstant le fait que la posture soit optimale ou sous-optimale, le fait d’être plus mobile sur une chaise aide à prévenir des céphalées cervicogéniques. Bref, on devrait toujours être relativement mobile sur une chaise. Dans le même ordre d’idées, le fait de se lever régulièrement devrait être encouragé. Aussi, les bureaux ajustables assis/debout représentent une option très intéressante.
Abstract
Spinal postural variability (SPV) is a prerequisite to prevent musculoskeletal complaints during functional tasks. Our objective was to evaluate SPV in cervicogenic headache (CeH) since CeH is characterized by such complaints. A non-randomized repeated-measure design was applied to compare SPV between 18 participants with reporting CeH aged 29–51 years, and 18 matched controls aged 26–52 years during a 30-min-laptop-task. Habitual spinal postures (degrees) of the cervical, thoracic and lumbar spine were analysed using 3D-Vicon motion analysis. SPV, to express variation in mean habitual spinal posture, was deducted from the postural analysis. Mean SPV of each spinal segment was lower in the CeH-group compared to the control-group. Within the CeH-group, SPV of all except one spinal segment (lower-lumbar) was higher compared to the group’s mean SPV. Within the control-group, SPV was more comparable to the group’s mean SPV. SPV differed between groups. Averaging data resulted in decreased SPV in the CeH-group compared to the control-group during the laptop-task. However, the higher within-group-SPV in the CeH-group compared to the group’s mean SPV accentuated more postural heterogeneity. It should be further determined if addressing individual SPV is a relevant intervention.
