A comparative clinical outcome study was conducted with two groups of physician-referred patients suffering either acute (Group A) or chronic (Group B) low back pain (LBP) and receiving treatment in a hospital-based comprehensive rehabilitation program. Twenty-six patients assigned to the acute-pain group suffered the onset of LBP within the preceding two months prior to treatment. Thirty patients assigned to the chronic pain group suffered the onset of LBP greater than six months prior to treatment. Results at discharge indicated minimal outcome differences between the treatment groups. However, at three-month follow-up the acute LBP group demonstrated a distinctly more favorable clinical outcome in terms of 1) maintenance of increased physical activity, 2) medication elimination, 3) reduction in subjective pain intensity, 4) reduction in healthcare utilization, and 5) return to productivity. Treatment implications regarding conservative versus restorative management approaches are discussed.
对两组由医生转诊的患者进行了一项临床疗效对比研究，这两组患者分别患有急性（A组）或慢性（B组）下背痛（LBP），并在一家医院的综合康复项目中接受治疗。分配到急性疼痛组的26名患者在治疗前的前两个月内出现LBP发作。分配到慢性疼痛组的30名患者在治疗前六个月以上出现LBP发作。出院时的结果表明治疗组之间的疗效差异最小。然而，在三个月的随访中，急性LBP组在以下方面表现出明显更有利的临床疗效：1）保持体力活动增加；2）停用药物；3）主观疼痛强度降低；4）医疗保健利用率降低；5）恢复工作能力。文中讨论了关于保守治疗与恢复性管理方法的治疗意义。
