OBJECTIVE
To compare the effectiveness of low and high frequency ultrasound (US)
technique for treatment of osteoarthritis (OA) of knee joint.
It is a pre-post design was used with multiple treatment therapies (A and B).
The study was conducted on the 310 patients. The patients were diagnosed
knee OA by the orthopedic doctor and recommended to the Physiotherapy
department of North and Clifton Campus of Ziauddin Hospital. In this study 310
patients were divided into two groups. Group A of 155 patients received low
frequency US treatment of 0.01MHz frequency for 10 min and at the same time
Group B of 155 patients received high frequency US treatment of 1MHz for
about 3 min. Both the groups had 6 sessions in 3 weeks.
There was a mean reduction in the pain and disability with difference of low
frequency US and high frequency US pre score and post score treatments of
both the groups is 1.2± 0.3 and 4.1± 1.0, there was statistically significant
difference between the effects of low frequency US and high frequency US in
pain management of knee O.A (P < 0.05).
There was difference between the effectiveness of low frequency US
