Chronic non-specific low back pain (LBP) may lead to functional impairment and physical disability. The aim of this study was to compare the effects of selective Pilates (SP) and extension-based (EB) exercises on pain, lumbar spine curvature, lumbar forward flexion range of motion (ROM), and physical disability in such individuals.
In this randomized clinical trial, Forty-seven patients with chronic non-specific LBP (Mean of age: 39.7 years) were randomly allocated into either SP (N = 16), EB (N = 15), or control (N = 16) groups. The measurements included pain intensity, physical disability, lumbar forward bending ROM, and lumbar spine curvature at the baseline, after receiving the 6-week interventions, and also following one month of cessation of the exercises The analysis of co-variance (ANCOVA) and Post-hoc Bonferroni tests were administered to compare the three groups after the interventions and one month later (P < 0.05).
More significant improvement was observed in SP group compared to the subjects receiving EB exercises in terms of pain, ROM, and physical disability (P < 0.001), however, there was no significant difference between the two experimental groups for lumbar curvature (P > 0.05). Furthermore; in follow-up, the patients in SP group significantly achieved a higher level of pain intensity improvement and lumbar flexion ROM than the EB exercises (P < 0.001).
It is estimated that core muscles activation and improving lumbopelvic rhythm in SP training may play a role in decreasing pain and physical disability in chronic LBP patients. Further high-quality studies are required to investigate the details of this mechanism.
慢性非特异性下腰痛（LBP）可能导致功能障碍和身体残疾。本研究的目的是比较选择性普拉提（SP）和伸展运动（EB）对这类患者的疼痛、腰椎曲度、腰椎前屈活动范围（ROM）和身体残疾的影响。
在这项随机临床试验中，47例慢性非特异性LBP患者（平均年龄：39.7岁）被随机分为SP组（N = 16）、EB组（N = 15）或对照组（N = 16）。测量指标包括基线时、接受6周干预后以及停止运动1个月后的疼痛强度、身体残疾程度、腰椎前屈ROM和腰椎曲度。采用协方差分析（ANCOVA）和事后Bonferroni检验比较干预后及1个月后的三组情况（P < 0.05）。
与接受EB运动的受试者相比，SP组在疼痛、ROM和身体残疾方面有更显著的改善（P < 0.001），然而，两组实验组在腰椎曲度方面无显著差异（P > 0.05）。此外，在随访中，SP组患者在疼痛强度改善和腰椎前屈ROM方面显著高于EB运动组（P < 0.001）。
据估计，SP训练中核心肌肉的激活和腰骨盆节律的改善可能在减轻慢性LBP患者的疼痛和身体残疾方面发挥作用。需要进一步的高质量研究来探究这一机制的细节。
