Back pain is one of the most costly disorders among the worldwide working population. Within that population, healthcare workers are at a high risk of back pain. Though they often demonstrate awkward postures and impaired balance in comparison with healthy workers, there is no clear relationship between compensatory postural responses to unpredictable stimuli and the strength of related muscle groups, in particular in individuals with mild to moderate back pain. This paper presents a study protocol that aims to evaluate the relationship between peak anterior to peak posterior displacements of the center of pressure (CoP) and corresponding time from peak anterior to peak posterior displacements of the CoP after sudden external perturbations and peak force during a maximum voluntary isometric contraction of the back and hamstring muscles in physiotherapists with non-specific back pain in its early stages. Participants will complete the Oswestry Disability Questionnaire. Those that rate their back pain on the 0-10 Low Back Pain Scale in the ranges 1-3 (mild pain) and 4-6 (moderate pain) will be considered. They will undergo a perturbation-based balance test and a test of the maximal isometric strength of back muscles and hip extensors. We assume that by adding tests of reactive balance and strength of related muscle groups in the functional testing of physiotherapists, we would be able to identify back problems earlier and more efficiently and therefore address them well before chronic back disorders occur.
背痛是全球劳动人口中最昂贵的疾病之一。在该人群中，医护人员患背痛的风险很高。尽管与健康工人相比，他们经常表现出不自然的姿势和平衡受损，但在不可预测刺激的代偿性姿势反应与相关肌肉群的强度之间没有明确的关系，特别是在轻度至中度背痛的个体中。本文介绍了一项研究方案，旨在评估在经历突发性外部干扰后，足底压力中心（CoP）的前峰到后峰位移的峰值与 CoP 从前峰到后峰位移的相应时间，以及在腰背和腿筋肌肉的最大自主等长收缩期间的峰值力之间的关系，研究对象为早期非特异性背痛的理疗师。参与者将完成 Oswestry 残疾问卷。那些在 0-10 腰痛量表上背痛评分为 1-3（轻度疼痛）和 4-6（中度疼痛）的人将被考虑。他们将接受基于扰动的平衡测试和腰背肌肉及髋关节伸肌最大等长力量测试。我们假设，通过在理疗师的功能测试中增加反应性平衡和相关肌肉群力量的测试，我们将能够更早、更有效地识别出背部问题，并在慢性背部疾病发生之前很好地解决这些问题。
