The program of treatment adapted from 10.First: Warm up ex’s as: Flexion trunk exercises (sit-up exercises) and Extension trunk from prone exercise repetitions was ten times with hold for 6 seconds at the end of the range. Second: Stretching exercises as: Raising leg ex’s, Double knee to chest, Fingers to toes, repetitions was 3 times with hold for thirty seconds. Third: Strengthening exercises for Back muscles as Bridging ex’s and Push-up, Lift one arm with opposite leg alternatively exercise, for Abdominal muscle as Posterior pelvic tilt exercise repetitions was 3 times with hold for 6 seconds.
Group B: Aquatic Therapy
Subjects in experimental group (B) performed underwater exercise with the examiner supervision in a comfortable heated pool by using.
Hubbard Tank: F Series 270 Gallon Stationary Full Body Immersion Tank
F-270-S is designed for treatment of upper and lower limbs allowing patients for full body immersion, motion and exercise. This Hubbard tank style with figure ”8” shape allows therapists to observe patient performance. Tank capacity is 270gallons; the water was heated to 34º to 36º C with duration of treatment 60 min/session. Every session contains 3 phases of exercises:
Phase (1) Warm up ex’s: ROM ex’s and relaxation for 5 min (Forward, backward, and sideway walking).
Phase (2)Progressive aquatic ex’s for 50 min (Range of motion of the joints of upper and lower extremities each ex’s done 10 repetitions, Stretching exercises each ex’s detained for twenty seconds then relaxed and repeated 3 times, & Strengthening exercises for back, abdominal muscles, upper and lower limb).
Phase (3) Cool down ex’s for 5 min (Slow walking forward, sideways, and backward).
Descriptive statistics and t-test were done to measure mean age, weight and height of groups. Mixed MANOVA was done to examine treatment effect by Visual Analogue Scale, Oswestry Disability Index and lumbar ROM.
No difference between groups regarding physi¬cal characteristics concerning age, weight, and height, As P;0.05. MANOVA revealed no significant differences in gen¬eral characteristics of the participants in the mean ages, heights, and weights, between two groups (p;0.05) table (1) .

Effect of aquatic and conventional therapy on VAS:
There was a significant reduce in the mean VAS following treatment in comparison with before treatment in both groups. Also, there was no significant difference in the mean values of the VAS pre ; post treatment between group A and B Table (2)
