The aim of the study was to determine the effectiveness of an extension-oriented exercise program in the prevention and management of low back/neck pain in nursery school teachers. A Cluster Randomized Controlled Trial was utilized. Seventy-one nursery school teachers working in nine school buildings were randomly divided into two groups, with each school as a unit of randomization. All the teachers in both groups received an ergonomic brochure; teachers in the experimental group also received an extension-oriented exercise program, conducted by a physical therapist. Data were collected at baseline and at a two-month follow-up. The primary outcome measure recorded was the level of disability (Roland Morris Disability Questionnaire and Oswestry Disability Index), while secondary outcome measure included the evaluation of cervical and lumbar physical discomfort (Visual Analogue Scale). At follow-up, a significant improvement was registered in the experimental group as compared to the control group for all the outcomes evaluated. In conclusion an extension-oriented exercise program may be a useful strategy to prevent low back and neck complaints and to reduce consequent LBP functional disability among nursery school teachers.
本研究的目的是确定一项以伸展运动为主的锻炼计划在预防和管理幼儿园教师腰/颈疼痛方面的有效性。采用了整群随机对照试验。在九所学校工作的71名幼儿园教师被随机分为两组，以每所学校作为随机单位。两组的所有教师都收到了一份人体工程学手册；实验组的教师还接受了由物理治疗师指导的以伸展运动为主的锻炼计划。在基线和两个月的随访时收集数据。记录的主要结局指标是残疾程度（罗兰·莫里斯残疾问卷和奥斯威斯残疾指数），次要结局指标包括对颈部和腰部身体不适的评估（视觉模拟量表）。在随访时，与对照组相比，实验组在所有评估的结局方面均有显著改善。总之，以伸展运动为主的锻炼计划可能是预防幼儿园教师腰颈不适并减少由此导致的腰痛功能残疾的一种有用策略。
