N/A Burn. Intervention 1: Intervention Group: Inspiratory muscle training will be added by Powerbreath Device include 30 breath twice a day for 3 weeks and more to incentive spirometry and chest physiotherapy In the intervention group . At first inspiratory muscle strenght will be measured in both groups (control /intervention) by Power Breath Device. The sign of inspiratory muscle weakness is inspiratory muscle strenght under 60 cmh2o. training in the intervention group is 30% of Pimax that is leveled primarily .This function will be done to investigate respiratory muscle strength and the quality of life of the patients in both groups(control/intervention) at the start and at the end of the intervention. Intervention 2: Control Group: The routine training including incentive spirometry and chest physiotherapy for 20 minutes once a day for 3 weeks and more will be done In the control group.
