will receive pilate exercise(1- bridging 2- shoulder bridge 3- front support 4- spine stretch forward 5- spine twist) and standard treatment (stretch hamstring , stretch lower back , strength abdominal muscles and electrical heat pad) for 12 sessions(3 sessions/week) over a period of four weeks.

will receiveMET treatment for hamstring and erector spinae and standard treatment(stretch hamstring , stretch lower back , strength abdominal muscles and electrical heat pad) for 12 sessions (3 sessions/week)over a period of four weeks.

will receive standard treatment(stretch hamstring , stretch lower back , strength abdominal muscles and electrical heat pad) only for 12 sessions (3 sessions/week) over a period of four weeks.

pilate group:1- bridging 2- shoulder bridge 3- front support 4- spine stretch forward 5- spine twist plus standard treatment(stretch hamstring -stretch lower back - strength abdominal muscles - electrical heat pad)

using visual analogue scale.each patient willbe instructed to rate the current level of pain by placing (X) sign across the horizontal VAS line. The distance in millimeters from the lower limit was measured using a ruler. VAS will be assessed before and after the treatment program.as 1:2 mild , 3:6moderate and 7:10 sever pain.

using ronald morris questioneer.The RMDQ is scored by adding up the number of items the patient has ticked. Scores can vary between 0-24. Greater levels of disability are reflected by higher scores

using BROMII.Use the two universal inclinometers to make flexion/extension measurements. Measurements with the universal inclinometer need to be with the patient in an upright position.

1. Palpate and mark S1 and T12. Mark on bare skin when possible. This avoids the marks moving with the patient's clothing (Fig.2)
2. Center the two inclinometers over the palpation marks and zero with your finger by spinning the dial (zero would then be at the bottom of the inclinometer).
3. Have the patient flex forward as far as possible (Fig. 3). Note the reading on each inclinometer.
4. The reading on the upper inclinometer is total lumbar flexion. The reading on the lower inclinometer is sacral flexion. The difference between the reading at S1 and T12 is true lumbar flexion.
5. Repeat flexion protocol for extension having the patient extend back for full extension instead of flexing forward

using V sit and reach test.The test is done twice with a short break in between . Scoring: Zero point is at the level of feet. (We note negative values towards our body and positive values outward from our body.) The best trial is recorded in centimeters by best score
