Ice massage compared to control had a statistically beneficial effect on ROM, function and knee strength. Cold packs decreased swelling. Hot packs had no beneficial effect on edema compared with placebo or cold application. Ice packs did not affect pain significantly, compared to control, in patients with OA. More well designed studies with a standardized protocol and adequate number of participants are needed to evaluate the effects of thermotherapy in the treatment of OA of the knee.
TENS, electroacupuncture and ice massage: comparison of treatment for osteoarthritis of the knee.
The purpose of this study was to compare the effectiveness of transcutaneous nerve stimulation (TENS), electroacupuncture (EA), and ice massage with placebo treatment for the treatment of pain. Subjects (n = 100) diagnosed with osteoarthritis (OA) of the knee were treated with these modalities. The parameters for evaluating the effectiveness of treatment include pain at rest, stiffness, 50 foot walking time, quadriceps muscle strength, and knee flexion degree. The results showed (a) that all three methods could be effective in decreasing not only pain but also the objective parameters in a short period of time; and (b) that the treatment results in TENS, EA and ice massage were superior to placebo.
