Does the performance of five back-associated exercises relate to the presence of low back pain? A cross-sectional observational investigation in regional Australian council workers

Objectives: investigate the relationships between the ability/inability to perform five physical test-exercises and the presence or absence of low back pain (LBP). Setting: regional Australian council training facility. Participants: consecutive participants recruited during 39 back education classes (8-26 participants per class) for workers in general office/administration, parks/gardens maintenance, roads maintenance, library, child-care and management. Total sample (n=539) was reduced through non-consent and insufficient demographic data to n=422. Age 38.6+/-15.3 years, range 18-64 years, 67.1% male. Methods: cross-sectional, exploratory, observational investigation. LBP presence was ascertained from a three-response option questionnaire: 0=none/rarely (NO) 1=sometimes (Some), 2=mostly/always (Most). Statistical correlation was performed with the number of the five test-exercises the individual successfully performed: 1) extension-in-lying, 3-seconds; 2) ‘toilet-squat’; feet flat...研究目标：探究完成五项体能测试动作的能力与腰背痛（Low Back Pain, LBP）发生与否之间的关联。 研究场景：澳大利亚某地区市政委员会培训设施。 研究对象：在39场背部健康教育培训课程中连续招募的参与者，每场次参与者人数为8~26名，受试者涵盖通用办公/行政、园区/园林维护、道路养护、图书馆、儿童保育及管理岗位工作人员。初始总样本量为539例，后因未签署知情同意及人口统计学数据不全，最终有效样本量为422例。参与者年龄为38.6±15.3岁，年龄范围18~64岁，男性占比67.1%。 研究方法：本研究为横断面探索性观察性调查。腰背痛的患病情况通过三项选项式问卷进行评估：0=无/极少出现（无）、1=偶尔出现（偶发）、2=经常/持续出现（频发）。以个体成功完成五项体能测试动作的数量作为分析指标，开展统计学相关性分析：1）卧位伸展动作，保持3秒；2）“蹲厕式深蹲”动作：双脚平放……
