Patients in the study group will treated with SNAGS techniques on thoracic spine with traditional treatment consist of ice application, supervised exercises (stretching and strengthening exercise) for 3 times/week for one month.

will receive only traditional treatment (ice application and supervised exercise ) for 3 times/week for one month.

Extension Thoracic Sustained Natural Apophyseal Glides :

Patient position: The patient sits astride the end of the table with hands placed behind the neck to protract the scapulae allowing access to the mid thoracic spine for the therapist's hand.

Therapist position: Therapist stands on their most efficient side for a centrally applied Sustained Natural Apophyseal Glides.

Therapist grasp: The therapist's mobilizing hand (ulnar border) will apply a cephalad glide in line with the facet joint plane of the involved spinal level and the other arm holds the thoracic wall above the level to be mobilized.

Traction is applied prior to glide, which is achieved by therapist knee extension

Repetitions: Three sets of ten repetitions will be done after a trial for the patient to be familial with the technique.

and traditional treatment.

the patient asked to choose from scale from zero (no pain) to 10 (worst pain) to detect his/her intensity of pain.

for flexion stationary Arm of the goniometer was aligned with the lateral border of the scapula (mid axillary arm), and the moving arm was aligned with the humerus.

for abduction the fulcrum was placed at the mid point of the posterior aspect of the glenohumeral joint, stationary arm was parallel to the trunk, and the moving arm was parallel to the longitudinal axis of the humerus. for internal and external rotation patient was in supine with the hips and knees flexed approximately 45°.The tested arm was supported on the table in 90° of abduction, elbow flexed 90°, and the wrist in neutral position.

the fulcrum was placed on the olecranon, stationary arm Placed perpendicular to the floor, and the moving arm parallel with the forearm.

the patients will asked to answer the questions on index . And then creating a percentage of pain and disability with higher scores indicating more severe limitation. The means of the two subscales are averaged to produce a total score ranging from 0 (best) to 100 (worst).

Minimum Detectable Change (90% confidence) = 13 points
