Abstract

PURPOSE:

We present final outcomes from the multiple-component Fit and Strong! intervention for older adults with lower extremity osteoarthritis.

DESIGN AND METHODS:

A randomized controlled trial compared the effects of this exercise and behavior-change program followed by home-based reinforcement (n=115) with a wait list control (n=100) at 2, 6, and 12 months. Fit and Strong! combined flexibility, aerobic walking, and resistance training with education and group problem solving to enhance self-efficacy for exercise and maintenance of physical activity. All participants developed individualized plans for long-term maintenance.

RESULTS:

Relative to controls, treatment participants experienced statistically significant improvements in self-efficacy for exercise (p=.001), minutes of exercise per week (p=.000), and lower extremity stiffness (p=.018) at 2 months. These benefits were maintained at 6 months and were accompanied by increased self-efficacy for adherence to exercise over time (p=.001), reduced pain (p=.040), and a marginally significant increase in self-efficacy for arthritis pain management (p=.052). Despite a substantially smaller sample size at 12 months, significant treatment-group effects were maintained on self-efficacy for exercise (p=.006) and minutes of exercise per week (p=.001), accompanied by marginally significant reductions in lower extremity stiffness (p=.056) and pain (p=.066). No adverse health effects were seen. Effect sizes for self-efficacy for exercise and for maintenance of physical activity were 0.798 and 0.713, and 0.905 and 0.669, respectively, in the treatment group at 6 and 12 months.

IMPLICATIONS:

This consistent pattern of benefits indicates that this low-cost intervention is efficacious for older adults with lower extremity osteoarthritis.
