Experimental group will receive lower limb strength training

control group will receive endurance training.

Experimental group will receive lower limb strength training treatment for three days a week and each session will last for an hour for 3 consecutivemonths. Measurement will be recorder pre-treatment and post treatment of both groupsat baseline,3rd, and 6th week.

Spirometry is one of the Pulmonary Function Test; they are useful investigations in the management of patients with respiratory disease or respiratory weakness secondary to neurological impairment. They aid diagnosis, help monitor response to treatment and can guide decisions regarding further treatment and intervention. Spirometry can measure all the lung volumes except residual volume.

The International Physical Activity Questionnaire is a 27-item self-reported measure of physical activity for use with individual adult patients aged 15 to 69 years old. The International Physical Activity Questionnaire can be used clinically and in population research that compares physical activity levels between populations internationally.To calculate MET minutes a week multiply the MET value given (remember walking = 3.3, moderate activity = 4, vigorous activity = 8) by the minutes the activity was carried out and again by the number of days that that activity was undertaken. For example if someone reports walking for 30 minutes 5 days a week then the total MET minutes for that activity are 3.3 X 30 X 5=495 Met minutes a week.
