EFFECT OF PHYSICAL TRAINING IN OBESE PATIENTS WITH LOW BACK PAIN: A SYSTEMATIC REVIEW

ABSTRACT Objective: To understand the hypoalgesic effect of exercises in obese patients with low back pain. Methods: From the methodological point of view, this is a systematic review study supported by the PRISMA guidelines (2020). Only clinical trials with defined eligibility criteria were included and the methodological evaluation was carried out using the Risk of Bias 2.0 (RoB 2.0) tool. Results: Four clinical trials were found, which underwent an assessment of risk of bias and were mostly categorized as moderate risk of bias or with some concerns. Conclusions: Moderate-intensity interval training (MIIT), high-intensity interval training (HIIT), and total resistance or lumbar spine extension exercises were shown to be effective for pain control, quality of life, and functional performance in obese individuals. On the other hand, the exercises alone did not produce a decrease in body composition. Level of evidence I; Systematic review.

摘要 目的：明确运动干预对肥胖合并腰痛患者的镇痛效应。方法：本研究为遵循PRISMA（2020）指南开展的系统评价研究。仅纳入纳入标准明确的临床试验，采用偏倚风险2.0（Risk of Bias 2.0, RoB 2.0）工具进行方法学质量评估。结果：最终纳入4项临床试验，经偏倚风险评估后，绝大多数被归类为中等偏倚风险或存在一定偏倚风险相关顾虑。结论：中等强度间歇训练（moderate-intensity interval training, MIIT）、高强度间歇训练（high-intensity interval training, HIIT）以及全身抗阻或腰椎伸展运动，可有效改善肥胖人群的疼痛控制效果、生活质量与功能表现；但单纯运动干预无法改善身体成分。证据等级：Ⅰ级；系统评价。
