DICLOFENAC SODIUM PHONOPHORESIS VERSUS CONVENTIONAL THERAPEUTIC ULTRASOUND IN KNEE OSTEOARTHRITIS
Purpose: to compare the effect of diclofenac sodium phonophoresis (DSPH) with conventional therapeutic ultrasound (TUS) on knee OA. Subjects and methods: Fifty patients (two groups) participated in this study. Group (A); consists of 25 patients (5 males, 20 females), with mean age 57 years, treated with TUS plus exercises. Group (B); consists of 25 patients (8 males, 17 females), with mean age 54 years, treated with DSPH plus exercises. Each patient was assessed for knee pain intensity level and physical function using the WOMAC score and knee flexion ROM using the digital inclinometer pretreatment, posttreatment and follow up one month after treatment. Results: There were non-significant differences among group (A) for WOMAC score, and significant only at posttreatment and follow up compared to pretreatment for group (B) (P- value <0.003*). Significant differences between posttreatment compared to pretreatment and follow up among group (A) for knee flexion ROM (P- value <0.03*), and significant only between post and pretreatment for group (B) (P- value = 0.000*). However, there was no significant difference between groups neither at posttreatment nor at follow up. Conclusion: DSPH had improvement but not significant in pain intensity level, physical function, and knee flexion ROM posttreatment but it had no superior effect on TUS. Knee flexion ROM improved significantly posttreatment in both groups, but only in PH the improvement sustained for one month after treatment. PH had long term effect than TUS.
