40 patients (male and female), patients age would be ranged from 30 to 50 years, would be randomly allocated using sealed envelope into randomly two matched group (A and B), Group A (Experimental): 20 patients would receive ultrasonic with ozonated gel as a coupling medium (phonophoresis) (1 MHz, 1 W/cm2continuous mode) for 5 min. plus, conventional physical therapy program consists of (conventional TENS (100 Hz) for 30 min - hot pack for 20 min- stretching and strengthening exercises, wrist rest splints). 3 times per week for 4 weeks.~Group B (control):20 patients will receive conventional physical therapy program consists of (conventional TENS (100 Hz) for 30 min - hot pack for 20 min- stretching and strengthening exercises, wrist rest splints) 3times per week for 4 weeks.
Comparison between 2 groups of chronic lateral epicondylitis, to determine the effect of ozonated media phonophoresis on chronic lateral epicondylitis.
