and objective. Osteoarthritis of the knee has maintained a
deviant stance against most therapeutic approaches. This study sought
to investigate the comparative efficacy of open kinetic-chain (OKC)
exercise and short wave diathermy (SWD) in the management of patients
with osteoarthritis (OA) of the knee.
methods. Forty five participants with knee OA consented to
participate and were attending the out-patient physiotherapy department
of a Nigerian teaching hospital volunteered for this study.
Participation inclusion criterion was grade II osteoarthritis of the
knee using the Kellgren and Lawrence classification based on X-rays.
Consecutive participants were randomly assigned into OKC exercise; SWD;
and combination of OKC and SWD group respectively. Pre and
post-treatment pain intensity, functional ability and range of motion
were recorded. Descriptive of mean and standard deviation and
inferential statistics of paired t-test and Analysis of Variance were
used for analysis. Alpha level was set at 0.05.
All treatment regimens had significant effects on pain, functional
ability and range of motion respectively (p<0.05). OKC exercise
had significant effect on pain reduction (p<0.001) and
similarly, there was significant improvement in functional ability and
range of motion in the SWD group while combination OKC and SWD group
exercise was found to be sufficient enough to improve pain in patients
with mild to moderate OA of the knee. However, combination of
OKC exercise and SWD seem to have better improvement on functional
ability and range of motion.
