Abstract

Abstract Introduction: Knee osteoarthritis (KOA) is a common degenerative disease in older people, causing pain, stiffness and dysfunction. Objective: To determine the influence of KOA on functional performance (FP), quality of life (QoL) and pain in older women. Method: This is a cross-sectional study, in which 50 older women diagnosed with KOA and 51 without KOA participated. Participants were assessed using FP tests: Sit-to-stand (STS); Gait speed test (GST); Timed Up and Go (TUG); 6-minute walk test (6 MWT) and the Berg Balance Scale (BBS). Pain was assessed by the visual analog scale (VAS); quality of life by applying the SF-36; and self-perception of the disease by using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Results: No intergroup statistical differences were found in the BBS (p: 0.42), STS (p: 0.59) and 6MWT (p: 0.97). However, the KOA group showed slower GS (p < 0.00) and longer time in TUG (p < 0.00). They also presented higher pain levels (p < 0.01), worse perceived health status regarding pain, stiffness and physical function (WOMAC) (p < 0.01), as well as worse QoL indices in functional capacity, physical limitations, pain and overall health status (p < 0.010). Conclusion: The results of the study demonstrate that older women with KOA showed a decline in FP, QoL and higher pain levels.

Summary

Introduction

Knee osteoarthritis (KOA) is a common degenerative disease in older people, causing pain, stiffness and dysfunction. Osteoarthritis (OA) is a chronic progressive osteoarticular degenerative disease with multifactorial etiology that manifests itself by arthralgia, stiffness and limited joint function, in addition to progressive cartilage loss and inadequate cartilage repair. It is the most frequent disease found in the population worldwide [1, 2], the most common cause of disability in older people, and the fourth main cause in women [3,4,5]. Anatomical changes caused by OA cause joint pain and a decline in muscle function, impacting the activities of daily living [11], such as prolonged standing, sitting and squatting [12], climbing stairs and activities involving flexion and knee extension [13]
