Abstract

Objective: This study aims to assess the effectiveness of a 12-weeks self-management and exercise intervention to improve self-efficacy in older individuals with knee osteoarthritis (KOA) DESIGN: Randomised Controlled Trial.

Setting: Four different community settings.

Subjects: Eighty individuals aged 60 years or over with clinical and radiographic knee osteoarthritis.

Intervention: The subjects were randomly assigned to (1) a combined self-management and exercise programme (treatment group) and (2) an educational programme (control group).

Main measures: The primary outcome was self-efficacy and secondary outcomes were physical activity, health-related quality of life and skill-related physical fitness measures.

Results: Sixty-seven participants, mean age 69.1 (5.8) years, completed the study: 32 in the control group and 35 in the treatment group. A significant group effect favourable to the treatment group was observed in the following variables: self-efficacy (F[2,64] = 9.2, p = 0.003), physical activity (F[2,64] = 43.6, p < 0.001) and balance for most painful knee (F(2,64) = 4.87, p = 0.031) and less painful knee (F[2,64] = 6.94, p = 0.010). No improvements regarding health-related quality of life, gait speed and agility were found. This study supports the importance of a combined self-management and exercise intervention to improve self-efficacy and physical activity in KOA individuals.

Keywords: controlled clinical trial; exercise; knee osteoarthritis; self-efficacy.
