will receive scapular proprioceptive neuromuscular facilitation exercise plus conventional treatment of lateral epicondylitis for 12 sessions (3 sessions per week for four weeks).

The conventional treatment of lateral epicondylitis will be:

1. Pulsed ultrasound over the lateral epicondyle for 5 min.
2. Five minutes of deep friction massage. It will be consisted of deep circular motions using the fingertips over the area of maximal tenderness at the lateral epicondyle.
3. Stretching exercise for extensor carpi radialis longus and brevis for 3 repetitions, each repetition will be 45 seconds with 30 seconds' rest.
4. Strengthening exercise for wrist extensors, eccentric exercise for wrist extensors will be as follow: 3 sets, 10 repetitions, 1 min rest interval between each set.

will receive shoulder strengthening exercise plus conventional treatment of lateral epicondylitis for 12 sessions (3 sessions per week for four weeks).

Same conventional treatment in group (A)

Scapular proprioceptive neuromuscular facilitation exercise: will be applied in two diagonals:

1. anterior elevation and posterior depression
2. posterior elevation and anterior depression for 3 sets of 10 repetitions, The rest interval between sets will be 20 seconds.

Patients will lay on the unaffected side while the therapist stands in the line of desired motion. Firstly, the therapist will give preparatory instructions. In the beginning of the pattern, the therapist pulls the scapula to the elongated position and then gives instructions for the desired movement.

(NPRS) is a unidimensional measure of pain intensity in adults. Consists of 11-item NPRS. The 11-point numeric scale ranges from '0' representing one pain extreme (e.g., "no pain") to '10' representing the other pain extreme (e.g., "pain as bad as you can imagine" or "worst pain imaginable.

The PRTEE is a valid and reliable tool that may be used in both research and clinical settings to assess the subjective outcome in patient with lateral epicondylitis. Subjects will be asked to rate the level of discomfort and difficulty they had encountered in the previous week. High total scores imply more pain and impairment; the scale spans from 0 to 100.

The PRTEE is a 15-item questionnaire designed to measure forearm pain and disability in patients with LE. The PRTEE allows patients to rate their levels of pain and disability from 0 to 10, and consists of 2 subscales:

1. PAIN subscale (0 = no pain, 10 = worst imaginable)

   • Pain - 5 items

2. FUNCTION subscale (0 = no difficulty, 10 = unable to do)

   • Specific activities - 6 items
   • Usual activities - 4 items

The Jammar hand grip dynamometer is valid and reliable, will be used to assess the subject's pain-free grip strength while they are lying on their side with their elbow extended and pronated. Subjects will be instructed to squeeze the dynamometer handles until they experienced pain. It will be performed three times with 20 s rest period between repetitions. Average of three trials will be recorded in kilograms.
