We explored differences in postural stability between subgroups of patients with low back pain (LBP) and varying risk levels for developing chronicity measured using the Subgroups for Targeted Treatment (STarT) Back Tool.
This was a cross-sectional, single-session, double-blind experimental study among 65 participants who had LBP for more than 14 days. Postural stability was assessed by measuring the center of pressure (COP) range, displacement area, and velocity in anterior-posterior and mediolateral directions under four sensory and cognitive conditions: (i) eyes open and counting forward, (ii) eyes closed and counting forward, (iii) eyes closed and counting forward in multiples of seven, and (iv) eyes closed and counting backward in multiples of seven. The participants were stratified into low-/medium- (n = 53) and high-risk (n = 9) subgroups.
There were no significant between-group differences among patients with LBP stratified as having a low/medium or high risk of chronicity in postural stability and sensory and cognitive conditions.
Impaired postural stability is important to consider when treating patients with LBP. However, we found that these impairments were not strongly aggravated in groups with a higher risk of chronicity, as measured using the STarT Back Tool.
我们探讨了使用 Subgroups for Targeted Treatment（STarT）Back 工具测量的慢性风险程度不同的腰痛（LBP）亚组患者之间姿势稳定性的差异。
这是一项横断面、单次、双盲实验研究，共纳入 65 名腰痛超过 14 天的参与者。通过测量在四种感觉和认知条件下前后向和左右向的压力中心（COP）范围、位移面积和速度来评估姿势稳定性：（i）睁眼并向前计数，（ii）闭眼并向前计数，（iii）闭眼并以七的倍数向前计数，以及（iv）闭眼并以七的倍数向后计数。参与者被分为低/中风险（n=53）和高风险（n=9）亚组。
在根据慢性风险程度分为低/中风险和高风险的 LBP 患者中，在姿势稳定性和感觉认知条件方面，两组之间没有显著差异。
在治疗腰痛患者时，需要考虑到姿势稳定性受损的问题。然而，我们发现，使用 STarT Back Tool 测量的慢性风险较高的组中，这些损伤并没有明显加重。
