背景:下腰痛(LBP)是一种常见疾病,被认为是全球残疾的主要原因之一,导致不良健康,社会,和经济结果。这项研究旨在探讨8周动态神经肌肉稳定(DNS)运动对疼痛的影响和持久性,功能性残疾,30至50岁非特异性慢性下腰痛(NSCLBP)患者的生活质量。
方法:这项研究采用了具有随访期的测试前和测试后设计,其中29名参与者(对照组16名,运动组13名)一直保持到研究结束。疼痛强度,功能性残疾,使用视觉模拟量表(VAS)评估生活质量,Oswestry残疾指数,和SF-36问卷,分别,干预前,紧接着,干预后两个月。对照组继续他们的日常活动,而锻炼组每周进行3次DNS锻炼,共8周。数据采用混合设计方差分析(P≤0.05)。
结果:结果显示疼痛改善(F(2,24)=5.31,P=0.01,η2=0.31),功能性残疾(F(2,24)=4.17,P=0.03,η2=0.26),和生活质量(F(2,24)=4.70,P=0.02,η2=0.28)在后测试中与预测试相比。然而,与后测和前测相比,随访评估中运动效果的持久性不具有可持续性(P>0.05)。
结论:为期8周的DNS练习可以改善疼痛,功能性残疾,NSCLBP患者的生活质量。然而,2个月的去训练期可以减少这些练习的积极结果。

BACKGROUND: 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).
METHODS: 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).
RESULTS: The results showed improvements in pain (F (2,24) = 5.31, P = 0.01, η2 = 0.31), functional disability (F (2,24) = 4.17, P = 0.03, η2 = 0.26), and quality of life (F (2,24) = 4.70, P = 0.02, η2 = 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).
CONCLUSIONS: 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.
