This study will be conducted to investigate the effect of scapular muscles (lower trapezius, middle trapezius and serratus anterior) strengthening on pain, pain free hand grip strength and functional outcome added to conventional physical therapy in patients with chronic Lateral Epicondylitis.
This study will try to investigate if scapular muscles strengthening have an effective role on pain, pain free hand grip strength and function when added to conventional physical therapy in patients with LE.

Ask the patient to raise arm above the head with upper extremity in line with lower trapezius muscle fibers in prone position with the shoulder joint at 135 degrees. The patient will be asked to hold position 6 seconds and perform 3 sets of 10 repetitions and 3times per week for 6 weeks.
Shoulder external rotation with the shoulder abducted 90ₒ and elbow flexed 90ₒ in prone position with elbow supported on the table. The patient will be asked to hold position 6 seconds and perform 3 sets of 10 repetitions and 3times per week for 6 weeks.
Ask the patient to raise the arm on a wall in the plane of the scapula in standing position. The patient will be asked to hold position 6 seconds and perform 3 sets of 10 repetitions and 3times per week for 6 weeks.

Assessment of change in pain intensity
Using Visual analouge scale (VAS), a continuous 10 cm line ranges from no pain to very severe pain which is valid and reliable tool. The patient marks on the line the point that they feel represents their pain intensity.
Time frame: at baseline and after 6 weeks of intervention
Assessment of change in hand grip strength
Patient stands with the elbow in complete extension and the shoulder and radioulnar joints in neutral rotation. Ask the patient to slowly squeeze the dynamometer and to stop the instant discomfort is first felt. It will be performed three repetitions separated by a 20-second rest interval. Average of three trials will be recorded. The measurement is valid and reliable.
Time frame: at baseline and after 6 weeks of intervention
Assessment of change in function
Using PRTEEQ. It is a 15-item self-reported questionnaire to measure perceived pain and disability in people with LE. It has three subscales: pain, usual activities and specific activities. Each of the items of the Patient rated tennis elbow evaluation questionnaire (PRTEEQ) is scored on a 0-10 scale, where 0 is 'no pain' or 'no difficulty' and10 is 'worst ever' or 'unable to do. Ask the patients to rate the pain and difficulty that they have experienced in the last week by marking the suitable response that reflects their current state. The total score ranges from 0 to 100, where high scores indicate greater pain and disability.
Time frame: at baseline and after 6 weeks of intervention

With a 20% duty cycle, frequency of 1 MHz and intensity of 1.5 w/cm² for 5 minutes 3 times per week for 6 weeks.
Put the elbow in extension, forearm in pronation and wrist in flexion with ulnar deviation. Hold for 30s and repeat 3 times with 30s rest in between. Three times per week for 6 weeks.
Ask the patient to extend elbow, pronate forearm, extend wrist and then flex the wrist slowly until full flexion is achieved. Patients should apply 3 sets of 10 repetitions 3 times per week for 6 weeks.
