The purpose of this study was to determine the efficacy of a
home-based kinesthesia, balance and agility (KBA) exercise
program to improve symptoms among persons age ≥ 50 years
with knee osteoarthritis (OA). Forty-four persons were randomly
assigned to 8-weeks, 3 times per week KBA, resistance
training (RT), KBA + RT, or Control. KBA utilized walking
agility exercises and single-leg static and dynamic balancing.
RT used elastic resistance bands for open chain lower extremity
exercises. KBA + RT performed selected exercises from each
technique. Control applied inert lotion daily. Outcomes included
the OA specific WOMAC Index of Pain, Stiffness, and Physical
Function (PF), community activity level, exercise self-efficacy,
self-report knee stability, and 15m get up & go walk (GUG).
Thirty-three participants [70.7 (SD 8.5) years] completed the
trial. Analysis of variance comparing baseline, mid-point, and
follow-up measures revealed significant (p < 0.05) improvements
in WOMAC scores among KBA, RT, KBA + RT, and
Control, with no differences between groups. However, Control
WOMAC improvements peaked at mid-point, whereas improvement
in the exercise conditions continued at 8-weeks.
There were no significant changes in community activity level.
Only Control improved exercise self-efficacy. Knee stability
was improved in RT and Control. GUG improved in RT and
KBA+RT. These results indicate that KBA, RT, or a combination
of the two administered as home exercise programs are
effective in improving symptoms and quality of life among
persons with knee OA. Control results indicate a strong placebo
effect in the short term. A combination of KBA and RT should
be considered as part of the rehabilitation program, but KBA or
RT alone may be appropriate for some patients. Studies with
more statistical power are needed to confirm or refute these
results. Patient presentation, preferences, costs, and convenience
should be considered when choosing an exercise rehabilitation
approach for persons with knee OA
