The purpose of this pilot study is to assess the impact of using walking sticks on walking perimeter in people with anterior spinal imbalance.

Aging is associated with a number of highly prevalent spinal pathologies, characterized by static disorders affecting spinal balance in the sagittal plane especially. These postural disorders are a source of pain, activity limitation and reduced quality of life. Treatment of spinal static disorders is essentially symptomatic based on medical care and rehabilitation and includes the use of spinal orthosis. Adherence to spinal orthosis is poor.

Walking requires dynamic stabilization capacities, which are affected by static disorders of the spine. In the case of walking difficulties associated with sagittal imbalance of spine, the walking aid most frequently assessed in the literature is the rollator. Using a rollator promotes anterior flexion of the spine and prevents physiological dissociation of the scapular and pelvic girdles.

Walking sticks help maintain sagittal alignment of the spine, improving the subject's dynamic stability while respecting the physiological gait pattern (dissociation of the scapular and pelvic belts).

To date, no study has assessed the impact of using walking sticks to increase walking activity in a population of people with sagittal imbalance of spine.

Deterioration in overall spinal balance and reduced stabilization capabilities are associated with increased risk of falls.
