In addition nerve mobilization, ultrasound therapy will be applied to all patient in experimental group via methods explained below.

In control group, patients will received only ultrasound therapy.

Passive neuromobilisation of the median nerve and functional self-exercises. The procedure started with the patient in the supine position. The following steps were taken in sequence: shoulder girdle depression; slight abduction of the elbow extension with arm lateral rotation and forearm supination; wrist, finger and thumb extensions were added; and the shoulder was taken into further extension.

To apply maximum stretch opposite cervical side flexion was done, and, in the end, the wrist was repeatedly moved into and out of stretch by performing a few degrees of flexion and extension at the wrist.

This mobilization technique will be performed by an experienced physician/physiotherapist three times a week for 3 weeks, and the patients will be given 3 sets of 15 cycles with a 1-minute rest period in each set.

The Median nerve's diameter will be evaluated bilaterally by another researcher blinded to interventions and experienced in musculoskeletal ultrasonography, using ultrasound with a 6-18 Mhz linear probe (Mindray-UMT 200, USA).

During the examination, patients will be seated on a stretcher, while the examiner sat on a higher stool.

The Median nerve will be evaluated by measuring the circumference of the nerve at the location where the nerve entered the carpal tunnel.

The ultrasound probe will be positioned above the epicondylus lateralis. The nerve cross-sectional area (CSA) will be recorded in the carpal tunnel while it was perpendicular to the wrist at 90 degrees on the Median nerve trace.

The nerve diameter will be measured from the circumference of the epineurium.

The grip strength of the hand is measured with the Jamar hand dynamometer recommended by the American Association of Hand Therapists (AETD).

The measurement will be performed in the standard position specified by the AETD; the patient will be seated, shoulders in adduction and neutral rotation, elbow in 90 degree flexion, forearm in mid-rotation and supported, wrist in neutral position with three repetitions and the results will be recorded in kilograms.

Pinch force will be measured in the same position as the hand grip strength is measured with a pincmeter.

It will be evaluated in two different positions, lateral and triple grip. When evaluating the lateral grip, the patient will be asked to press the pinchmeter from the top with the middle of the distal phalanx of the thumb and support the lower part of the pinchmeter with the second phalanx of the index finger.

When evaluating the triple grip, measurements will be made by squeezing the thumb on one side of the pinchmeter an
