Abstract

OBJECTIVE

The association between pain catastrophizing and ability to perform activities of daily living (ADL) requiring weight bearing, in particular stair climbing, standing from a seated position, and walking, in individuals with knee osteoarthritis (OA) is unclear. This study aimed to investigate the association between pain catastrophizing and ability to perform these ADLs by this population.

METHOD

This cross-sectional study included individuals with knee OA (Kellgren and Lawrence grades 1-4). The ability to perform ADL was evaluated using the knee OA-related health domain measure (Japanese Knee Osteoarthritis Measure). Pain catastrophizing was evaluated using the Pain Catastrophizing Scale. The association between pain catastrophizing and ability to perform ADL, in particular stair climbing, standing from a seated position, and walking, was evaluated using the logistic regression analysis. Three types of sensitivity analysis were performed to validate the results of the logistic regression analysis.

RESULTS

A total of 151 participants were included in the final analysis. When adjusted for covariates, those with pain catastrophizing showed significantly decreased stair climbing ability (odds ratio 8.84; 95% confidence interval 1.37 to 56.92). Moreover, the results did not change even with sensitivity analysis. By contrast, when adjusted for covariates, those with pain catastrophizing did not show significantly decreased ability to stand from a seated position and walk.

CONCLUSION

Pain catastrophizing in knee OA patients showed significantly decreased stair climbing ability. There is a need to consider the effect of pain catastrophizing in rehabilitation of knee OA patients with decreased ability to climb stairs.Key Points• Pain catastrophizing in knee OA patients showed significantly decreased stair climbing ability.• Ability to stand from a seated position and walk were not affected by pain catastrophizing.• There is a need to consider the effect of pain catastrophizing in rehabilitation of knee OA patients with decreased ability to climb stairs.

摘要

目的

疼痛灾难化与膝关节骨关节炎（OA）患者日常活动能力（ADL）的关联尚不清楚，特别是负重活动，如爬楼梯、从座位站立和行走。本研究旨在调查该人群中疼痛灾难化与这些 ADL 能力之间的关系。

方法

这是一项横断面研究，纳入膝关节 OA（Kellgren 和 Lawrence 分级 1-4 级）患者。使用膝关节 OA 相关健康领域测量量表（日本膝关节骨关节炎测量量表）评估 ADL 能力。使用疼痛灾难化量表评估疼痛灾难化。使用逻辑回归分析评估疼痛灾难化与 ADL 能力，特别是爬楼梯、从座位站立和行走之间的关系。进行了三种类型的敏感性分析以验证逻辑回归分析的结果。
