To investigate demographic, symptom-related and cognitive determinants of cane use for knee osteoarthritis (OA) and prioritise the factors that could facilitate cane use in people with no previous cane use.
A survey of people aged ≥45 years with a clinical diagnosis of knee OA was conducted. The survey included two sections: i) demographic and cognitive determinants of cane use assessed via subscales of the Cane Cognitive Mediator Scale; ii) 19 statements, underpinned by the Behaviour Change Wheel theoretical framework, relating to factors that could facilitate regular cane use. Logistic regression was used to examine determinants of cane use while a priority pairwise ranking activity (1000minds) determined the rank order of the 19 statements that could facilitate cane use.
529 people completed Part 1 (80% females; 35% cane users) and 231 people completed Part 2. Age (OR 1.06, 95% CI 1.03, 1.09), body mass index (BMI) (OR 1.03, 95% CI 1.01, 1.06), knee pain ≥3 years (OR 2.62, 95% CI 1.63, 4.21) and numeric rating scale pain level whilst walking (OR 1.19, 95% CI 1.09, 1.30) were significant independent determinants of cane use. In people who had never used a cane, statements relating to cane use technique, fitting, knowledge of benefits and motivation were ranked highest overall.
Independent determinants of cane use include older age, higher BMI, greater pain duration and greater severity of knee pain. Strategies targeting an individual’s capability and motivation to use a cane may increase cane use among people with knee OA. This article is protected by copyright. All rights reserved.
