Low back pain (LBP) is a common disorder and is considered one of the leading causes of disability worldwide, resulting in adverse health, social, and economic outcomes. This study aimed to investigate the effects and durability of 8-week Dynamic Neuromuscular Stabilization (DNS) exercises on pain, functional disability, and quality of life in individuals aged 30 to 50 years with non-specific chronic low back pain (NSCLBP).
This research employed a pre- and post-test design with a follow-up period, in which 29 participants (16 in the control group and 13 in the exercise group) remained until the end of the study. Pain intensity, functional disability, and quality of life were assessed using the visual analog scale (VAS), the Oswestry Disability Index, and the SF-36 questionnaire, respectively, before intervention, immediately after, and two months post-intervention. The control group continued their routine daily activities, while the exercise group performed DNS exercises three times a week for 8 weeks. The data was analyzed using a mixed-design ANOVA (P ≤ 0.05).
The results showed improvements in pain (F (2,24) = 5.31, P = 0.01, η = 0.31), functional disability (F (2,24) = 4.17, P = 0.03, η = 0.26), and quality of life (F (2,24) = 4.70, P = 0.02, η = 0.28) in the exercise group at the Post-test compared to the Pre-test. However, the durability of the exercise effects at the follow-up assessment was not sustainable compared to the Post-test and Pre-test (P > 0.05).
An 8-week period of DNS exercises can improve pain, functional disability, and quality of life in individuals with NSCLBP. However, a 2-month period of detraining can reduce the positive outcomes of these exercises.

腰痛（LBP）是一种常见疾病，被认为是全球致残的主要原因之一，会导致不良的健康、社会和经济后果。本研究旨在调查为期8周的动态神经肌肉稳定化（DNS）训练对30至50岁非特异性慢性腰痛（NSCLBP）患者的疼痛、功能障碍和生活质量的影响及持续性。
本研究采用前后测试设计并设有随访期，29名参与者（对照组16名，训练组13名）完成了整个研究。在干预前、干预后即刻以及干预后两个月，分别使用视觉模拟量表（VAS）、奥斯维斯特残疾指数和SF - 36问卷评估疼痛强度、功能障碍和生活质量。对照组继续其日常活动，而训练组每周进行3次DNS训练，共8周。使用混合设计方差分析对数据进行分析（P≤0.05）。
结果显示，与测试前相比，训练组在测试后疼痛（F(2,24)=5.31，P = 0.01，η = 0.31）、功能障碍（F(2,24)=4.17，P = 0.03，η = 0.26）和生活质量（F(2,24)=4.70，P = 0.02，η = 0.28）方面均有改善。然而，与测试后和测试前相比，随访评估时训练效果的持续性并不显著（P>0.05）。
为期8周的DNS训练可改善NSCLBP患者的疼痛、功能障碍和生活质量。然而，两个月的训练中断会降低这些训练的积极效果。
