1. Stretching of the erector spinae,
2. latissimus dorsi, gluteus Medius, gluteus minimums, and gluteus maximus (knee to chest) Pelvic Bridging Exercises
3. Strengthening Exercises of latissimus dorsi muscle
4. Pelvic Bridging Exercises include the gluteus maximus and quadriceps
5. Rocker board:

Trunk control exercises on Rocker Board in standing position first in medio-lateral direction for 10 min and then in anterio-posterior direction for 10 min with breaks in between.

1. Stretching of the latissimus dorsi muscle
2. Functional use and strengthening of the latissimus dorsi.
3. Functional strengthening of abdominal and oblique abdominal muscles
4. Placing exercises to facilitate trunk extension
5. Rotations and counter-rotations (right and left) of the hips with the trunk extended Training of lumbar spine stabilizers

Functional reach of shoulder, anterior, right, and left sides.

Then intervention will be applied to the perturbation group as mention below at Rocker board (50 x 45 cm).the group will perform 36 sessions (4 times per week over 8 weeks) and effects of interventions will be measured before treatment, at 4th and after8th week (pre, mid and post intervention). Trunk control exercises on Rocker Board in standing position first in medio-lateral direction for 10 min and then in anterio-posterior direction for 10 min with breaks in between.

It is used to measure motor impairment of the trunk after stroke. The total score for TIS ranges between 0 for a minimal performance to 23 for a perfect performance "Change will be measured from Baseline to 6 weeks"

It is for the assessment of lower extremity function, mobility and fall risk. scoring criteria < 10 seconds = normal. < 20 seconds = good mobility; can walk outside alone; does not require a walking aid. < 30 seconds = walking and balance problems; cannot walk outside alone; requires walking aid. "Change will be measured from Baseline to 6 weeks"

It is used for the assessments of postural control in stroke patients. It measures the ability of an individual with stroke to maintain stable postures and equilibrium during positional changes. It consists of a 4-point scale where the items are scored from 0 to 3, and the total scoring ranges from 0 to 36. "Change will be measured from Baseline to 6 weeks"

It is for assessment of postural stability during walk. 3 Normal is able to ambulate for 10 steps heel to toe with no staggering. 2 Mild impairment, ambulates 7-9 steps. 1 Moderate impairment, ambulates 4-7 steps. 0 Severe impairment, ambulates less than 4 steps heel to toe or cannot perform without assistance. "Change will be measured from Baseline to 6 weeks"

It evaluate self-efficacy as a result of being able to successfully perform a specific action in stroke patients. It is a self-reported questionnaire about level of confidence reported on a 0 to 10 scale (0 = not confident, 10 = very confident) when completing 13 activities of daily life following stroke. "Change will be measured from Baseline to 6 weeks"
