项目摘要

DESCRIPTION (provided by applicant): The primary aims of this proposal are to determine how physical and psychological factors interact in the recovery process following an initial episode of low back pain and to determine how these factors contribute to risk for recurrence. Specifically, we propose to assess the relationship between motor coordination strategies (changes in lumbar and pelvic movement patterns) and levels of kinesiophobia (fear of painful re-injury upon physical movement) following an initial episode of low back pain. Two studies are proposed. Study 1 will examine movement patterns during performance of standardized reaching tasks in low back pain patients with high versus low levels of kinesiophobia. Participants will be assessed at 3, 6, and 12 weeks after onset of symptoms to track changes in motor coordination. By examining the relative magnitude of lumbar and pelvic motions used by low back pain patients who are high and low kinesiophobia, this design will allow us to track changes in the dynamic relationship between motor coordination and kinesiophobia during the process of recovery from acute low back pain. We hypothesize that lumbar motion will be significantly reduced in low back pain patients who are high versus low in kinesiophobia. Study 2 will examine movement patterns during standardized reaching tasks in individuals who have recently recovered from low back pain. Using a longitudinal design, we will develop a survival model to assess the risk for recurrence in the year following an initial episode of low back pain based on measures of spinal motion and kinesiophobia. We hypothesize that the highest risk of recurrent back pain will be observed in those who are high in kinesiophobia and who exhibit reduced spinal motion. The current proposal brings together promising ideas from motor coordination and health psychology literatures to provide an innovative integration of the best predictors of recurrent low back pain. The short-term goal of this research is characterize how spinal motion parameters and kinesiophobia interact to promote or delay recovery from acute low back pain. Our long-term goal is to use this information to develop an assessment protocol that can be easily adopted into clinical practice.

描述（由申请人提供）：本提案的主要目的是确定腰痛初次发作后的恢复过程中身体和心理因素如何相互作用，并确定这些因素如何导致复发风险。具体来说，我们建议评估腰痛初次发作后运动协调策略（腰椎和骨盆运动模式的变化）与运动恐惧症（害怕身体运动时再次受伤的疼痛）水平之间的关系。提出了两项研究。研究 1 将检查具有高水平和低水平运动恐惧症的腰痛患者在执行标准化伸展任务期间的运动模式。参与者将在症状出现后 3、6 和 12 周接受评估，以跟踪运动协调的变化。通过检查高低运动恐惧症的腰痛患者使用的腰部和骨盆运动的相对幅度，该设计将使我们能够跟踪急性腰痛恢复过程中运动协调性和运动恐惧症之间动态关系的变化。我们假设运动恐惧症高的腰痛患者与运动恐惧症低的患者相比，腰部运动会显着减少。研究 2 将检查最近从腰痛中恢复的个体在标准化伸展任务中的运动模式。使用纵向设计，我们将开发一个生存模型，根据脊柱运动和运动恐惧症的测量来评估腰痛初次发作后一年内复发的风险。我们假设，运动恐惧症高且脊柱运动减少的人出现复发性背痛的风险最高。目前的提案汇集了来自运动协调和健康心理学文献的有前途的想法，以创新方式整合复发性腰痛的最佳预测因素。这项研究的短期目标是描述脊柱运动参数和运动恐惧症如何相互作用以促进或延迟急性腰痛的恢复。我们的长期目标是利用这些信息来开发一个可以轻松应用于临床实践的评估方案。
