The aim of this study was to investigate whether self-reports of work ability correlated to the results of quantitative tests measuring physical capacity and a questionnaire assessing psychological mood in vibration-exposed patients with hand symptoms.
The participants comprised 47 patients (36 men and eleven women) with exposure to hand vibration and vascular and/or neurological symptoms in the hands. They performed several quantitative tests (manual dexterity, hand grip strength, finger strength) and completed the Work Ability Index (WAI) and Hospital Anxiety and Depression Scale (HADS) questionnaires.
Correlation analysis revealed statistically significant associations between the WAI results, the HADS indices, hand grip and finger strength, and manual dexterity measured using the Purdue Pegboard®. Multiple regression analysis revealed age and HADS indices as the strongest predictors of work ability.
The patient's age and psychological mood may be stronger predictors of work ability compared with results from tests measuring physical capacity of the hands in vibration-exposed patients with hand symptoms. When using the WAI as an instrument for assessing work ability in these patients, health care providers need to be more aware of the impact of the psychological mood.
本研究旨在探讨手部振动暴露患者手部症状患者的自我报告工作能力与测量身体能力的定量测试结果和评估心理情绪的问卷结果是否相关。
参与者包括 47 名(36 名男性和 11 名女性)手部暴露于手部振动以及血管和/或神经症状的患者。他们进行了多项定量测试(手灵巧性、手部握力、手指力量),并完成了工作能力指数(WAI)和医院焦虑和抑郁量表(HADS)问卷。
相关性分析显示,WAI 结果、HADS 指数、手握力和手指力量以及使用 Purdue Pegboard®测量的手灵巧性之间存在统计学显著关联。多元回归分析显示,年龄和 HADS 指数是工作能力的最强预测因素。
与测量手部振动暴露患者手部生理能力的测试结果相比,患者的年龄和心理情绪可能是工作能力的更强预测因素。当使用 WAI 作为评估这些患者工作能力的工具时,医疗保健提供者需要更加注意心理情绪的影响。
