High Intensity Interval Inspiratory Training Effect on Ventilatory Functions and Diaphragmatic Excursion in Forward Head Posture

Overview

PURPOSE: ……… The purpose of the study is to investigate the effect of interval inspiratory muscle training on respiratory functions in subjects with forward head posture associated with chronic nonspecific neck pain BACKGROUND: Alteration of head and neck positions can have an immediate negative effect on respiratory function. Clinicians should be prompted to assess respiratory function when assessing individuals with FHP and decrease the tension on respiratory system to avoid consequence. Also FHP has a negative effect on chest expansion and diaphragmatic function the incidence of forward head posture increases nowadays due to increase using of smartphones HYPOTHESES:: There will be no a significant effect of interval inspiratory muscle training on respiratory functions in chronic forward head posture subjects. RESEARCH QUESTION: Will the interval inspiratory muscle training improve respiratory functions in subjects forward head posture associated with chronic nonspecific neck pain?

* For evaluation: we will assess 1-diaphragmatic excursion using ultrasonography 2- ventilatory functions using spirometer 3- chest expansion using tape measurement 4- height and weight scale to detect BMI 5- Craniocervical angle * For treatment: we will use 1- threshold inspiratory muscle trainer And they will be randomly allocated into two groups: Experimental Group: Thirty subjects will receive combined program containing interval inspiratory muscle training and conventional exercise program for FHP 12 weeks (3 sessions/ week) Control Group : Twenty subjects will receive conventional exercise program for FHP 12 weeks (3 sessions/ week)
