Abstract

Background and Aim: Knee osteoarthritis is the most common cause of disability in many societies. Therapeutic measures such as using anti-inflammation drugs and physiotherapy programs have been used to suppress knee pain and improve knee joint function in patients with knee osteoarthritis. The aim of this study was to compare the effects of iontophoresis of piroxicam gel, galvanic current with or without  piroxicam gel on pain, functional ability and knee muscle strength in patients with knee osteoarthritis.
Materials and Method: This study was a clinical trial conducted in Akhtar hospital. Forty two female patients (mean age 58.52 years old) with knee osteoarthritis participated in this study. The protocol was performed in Physiotherapy Clinic of Mazandaran Medical University, Mazandaran, Iran. All patients were randomly assigned to three groups. Iontophoresis of piroxicam gel was applied for group 1 (n=14), proxicam gel for group 2 (n=14) and galvanic current for group 3 (n=14). The procedure was carried out for 20-minutes, three times a week and for two following weeks. Knee pain and functional ability were estimated by knee injury and osteoarthritis outcome score (KOOS) questioner and the strength of knee extensor and flexor muscles by an isometric device just before the first treatment and immediately after the last treatment times.
Results:A significant decrease in pain and a significant increase in functional ability and the strength of knee extensor muscles were resulted in all studied groups (P < 0.05).  According to ANOVA test, the level of the percentage difference which was computed for KOOS and knee muscle strength before and after treatments was significantly higher in group 1 than the other two (P < 0.01).
Conclusion:  Pain and knee functional ability were significantly improved in patients in all three methods. But iontophoresis of piroxicam gel appeared to be more effective in relieving pain and improving knee functional abilities than the application of galvanic current or piroxicam gel alone. Iontophoresis facilitated the transmission of piroxicam gel through the skin.
