To investigate symptom trajectories in chiropractic patients with lumbar spinal stenosis (LSS).
Patients diagnosed with LSS were recruited from chiropractic clinics and self-reported questionnaires were collected at baseline and 1-year follow-up. Patients received weekly text messages about low back pain (LBP) and leg symptoms for 1 year. Group-based trajectory modelling was performed to identify symptom trajectory groups. The groups were compared based on patient characteristics, LBP and leg pain intensity, Oswestry Disability Index (ODI) and Zurich Claudication Questionnaire (ZCQ).
A total of 90 patients were included in the analysis. A three-group trajectory model was chosen: 'improving' (16%), 'fluctuating/improving' (30%), and 'persistent' (54%). The 'persistent' group had a higher proportion of women [71% (95% CI 57-82%)] than the 'improving' group 29% (95% CI 11-56%), and a higher ODI score at both baseline [34.2 (95% CI 29.7-38.8) vs. 22.8 (16.4-29.1)] and 1-year follow-up [28.1 (95% CI 23.2-33.0) vs. 4.8 (0.1-9.4)]. Similar differences were observed for ZCQ symptom and function scores.
Pain symptoms in people with LSS followed distinctly different trajectories. Half of the sample had a pattern of consistently severe symptoms over a year, while the other half either improved rapidly or experienced fluctuating symptoms with some improvement.
探讨腰椎管狭窄症（LSS）患者的症状轨迹。
从脊骨疗法诊所招募诊断为 LSS 的患者，并在基线和 1 年随访时收集自我报告的问卷。患者在 1 年内每周都会收到有关下腰痛（LBP）和腿部症状的短信。采用基于群组的轨迹建模来识别症状轨迹组。根据患者特征、LBP 和腿部疼痛强度、Oswestry 残疾指数（ODI）和苏黎世跛行问卷（ZCQ）对组进行比较。
共有 90 名患者纳入分析。选择了一个三群组轨迹模型：“改善”（16%）、“波动/改善”（30%）和“持续”（54%）。“持续”组中女性比例较高[71%（95%CI 57-82%）]，而“改善”组为 29%（95%CI 11-56%），基线和 1 年随访时的 ODI 评分均较高[34.2（95%CI 29.7-38.8）比 22.8（16.4-29.1）]和[28.1（95%CI 23.2-33.0）比 4.8（0.1-9.4）]。ZCQ 症状和功能评分也观察到类似的差异。
LSS 患者的疼痛症状呈现出明显不同的轨迹。一半的样本在一年中表现出持续严重的症状模式，而另一半则迅速改善或经历波动症状，有一定程度的改善。
