All women in both groups (A&B) will receive postural correction exercises which includes:

A.mckenzie exercises:

The exercise routine consists of seven types of movements,at static maximum strength, with 15_20 repetitions, holding each repetition for seven seconds.the subjects complete one 20-minutes set per day,three times a week for four weeks B.strengthening exercise targeted the periscapular muscles (Y to W,l to W), scapular retraction.strengthening exercises will be progressively performed for 3sets, with 10 to15 repetitions C.pectoralis flexibility on a foam roller.Hold for 5seconds and repeated 10 time s

All women in group (B) will receive shockwave therapy once a week for the duration of the trial (4 weeks)

The dosage used will be as the following:

Energy flux Density (EFD)=0,25 ml/mm2 Number of shocks=1000 shocks(kamel et al.,2020). Time:2-5minutes per session.

Shockwave therapy session once a week for month 1000shock per session

Pain level will be assessed for both groups (A&B) before and after treatment program by using (VAS). scores are based on self-reported measures of symptoms that are recorded with a single hand written mark placed at one point along the length of a10 cm line."0 cm" means no pain."10cm" means maximum pain.

Pain threshold for each woman in both groups (A&B) will be measured before and after the treatment program by using "Pressure Algometer" . The pressure pain threshold measurements for trapezius will be performed at mid-way between the seventh cervical vertebrae and acromial angle in limited area in the second and third quadrants (Barbero et al.' 2013).
