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

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

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)

Inclusion Criteria:

• Sixty subjects (female) have forward heads and Their craniocervical angle is from 30 to 50°
• Their body mass index ranged from (24.9 -29.9) kg/m2

Exclusion Criteria:

• Chest diseases (either obstructive or restrictive).
• Smoker patient.
• Clinical signs of a severe cardiac event. (eg, congestive heart failure),
• Neurological disorders affecting respiratory muscles or any muscular dystrophies (cervical disc or bulge).
• Patient with haemodynamic instability.
