This study examines the relationship between functional disability and work ability in workers affected by low back pain (LBP) through an analysis of correlations between the Oswestry Disability Index (ODI) and Work Ability Index (WAI). The role of personal and work factors on functional disability/work ability levels has also been studied. LBP is the most common musculoskeletal problem and a major disabling health problem worldwide. Its etiology is multifactorial. Multidisciplinary approaches may help reduce the burden of pain and disability and improve job continuity and reintegration at work.
A cohort of 264 patients affected by LBP from an Italian outpatient clinic were included in a clinical diagnostic/therapeutic trial aiming at rehabilitation and return to work through an integrated investigation protocol. Data were collected during the first medical examination using anamnestic and clinical tools. The final sample is composed of 252 patients, 57.1% man, 44.0 % blue collars, 46.4% with the high school degree, 45.6% married.
WAI and ODI reported a negative and fair correlation (r = -0.454; p = .000). Workers with acute LBP symptoms have a higher probability of severe disability than those with chronic LBP symptoms. White collars without depressive symptoms reported higher work ability - even in chronic disability conditions-than those with depressive symptoms.
The study found that ODI and WAI have a convergent validity and this suggests that the two tools measure capture distinctive aspects of disability related to personal, environmental, and occupational characteristics. The most important and modifiable prognostic factors found for ODI and WAI were depressive symptoms, workday absence, and intensity of back pain. The study also found a mild association between age and ODI. The study's findings highlight the importance of using a multidisciplinary approach to manage and prevent disability due to LBP.
本研究通过分析奥斯威斯残疾指数（ODI）和工作能力指数（WAI）之间的相关性，探讨了下背痛（LBP）患者的功能残疾与工作能力之间的关系。同时，还研究了个人因素和工作因素对功能残疾/工作能力水平的影响。LBP是全球最常见的肌肉骨骼问题，也是导致残疾的主要健康问题，其病因是多因素的。多学科方法可能有助于减轻疼痛和残疾负担，提高工作连续性和重返工作岗位的能力。
来自意大利一家门诊诊所的264名LBP患者被纳入一项临床诊断/治疗试验，该试验旨在通过综合调查方案实现康复和重返工作岗位。在首次体检时，使用问诊和临床工具收集数据。最终样本由252名患者组成，其中男性占57.1%，蓝领占44.0%，高中学历占46.4%，已婚者占45.6%。
WAI和ODI呈负相关且相关性中等（r = -0.454；p = 0.000）。急性LBP症状的工人比慢性LBP症状的工人有更高的严重残疾概率。没有抑郁症状的白领即使在慢性残疾状态下，其工作能力也高于有抑郁症状的白领。
该研究发现ODI和WAI具有收敛效度，这表明这两种工具测量捕捉到了与个人、环境和职业特征相关的残疾的不同方面。ODI和WAI最重要且可改变的预后因素是抑郁症状、工作日缺勤和背痛强度。该研究还发现年龄与ODI之间存在轻度关联。研究结果强调了采用多学科方法管理和预防LBP导致的残疾的重要性。
