چکیده انگلیسی


• Spinal angles were recorded during a functional lifting task in subjects suffering from low back pain (LBP) and in healthy controls.
• Recurrence quantification analysis revealed that the structure of the variability of spinal angular movement was more deterministic (less random) for the LBP group.
• This method offers a new approach to detect movement impairment in LBP.

ObjectivesTo apply a novel method to assess the characteristics of spinal movement in subjects with low back pain (LBP) in a functional task.Methods17 subjects suffering from chronic non-specific LBP (average pain intensity: 1.8 ± 1.6), and 17 age and gender matched controls performed a repetitive lifting task. Spinal movement was recorded using a novel sensor strip with 12 angle sensors recording the spinal dynamics in evenly spaced (25 mm) locations along the spine. Recurrence quantification analysis was applied to different components of the angles to assess the structure of its variability.ResultsMechanically, the LBP and control group performed the task similarly. Reported pain increased in the LBP group, yet task-related angular movement was not different. However, the percentage of determinism for the accessory angular movement (movement variability not directly related to task execution) was significantly higher for the LBP group, indicating a more deterministic (less random) structure of the muscle activation pattern variability.ConclusionThe structure of the variability of spinal movement differs in subjects with chronic non-specific LBP.SignificanceThe determinism of accessory spinal movement may be a useful measure for evaluation of movement impairment in LBP and for monitoring rehabilitation effects.
