This study was aimed at investigating the relationship among pain, walking time, physical function PF and health-related quality of life HRQoL in patients with knee OA.
Ninety-six individuals with knee OA. PF, pain, walking time (at comfortable and fast paces) and HRQoL were assessed using Ibadan Knee Hip Osteoarthritis Outcome Measure, Visual Analogue Scale, stopwatch, and Arthritis Impact Measurement Scale respectively. Data were analyzed using descriptive statistics, Pearson's correlation test and linear multiple regression with alpha level set at 0.05.
The mean age of the participants was 61.27±13.73 years. There were significant correlations between average daily pain (ADP) and PF (r =-0.21) and pain intensity and HRQoL (r = 0.47); and between pain during walking and each of PF and HRQoL (r =-0.29 and 0.37). The correlations between comfortable pace walking time (CPWT) and each of ADP, PF and HRQoL were also significant (r = 0.33, -0.87, 0.31). Regression analysis indicated that a negative relationship existed between PF and each of pain during walking and CPWT (R2 = 0.768) while HRQoL is positively related to ADP, pain during walking and CPWT (R2 = 0.318).
Pain during walking and CPWT were the most significant predictors of physical function and health-related quality of life in patients with knee osteoarthritis.
