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

Not Applicable

Completed

• Conditions: FHD
• Interventions: Device: Threshold Inspiratory muscle trainer; Other: posture correction exercises

• Registration Number: NCT06571578
• Lead Sponsor: Cairo University

Brief Summary

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?

Detailed Description

* 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)

Primary Outcome Measures

Name	Time	Method
Diaphragmatic execursion	3 months	Diaphragmatic sonography model (LOG IQ E10S) for measuring diaphragmatic excursion changes.in centimeter
improve ventilatory functions	3 months	measure ventilatory functions in percentage from predictied using spirometery (Digital-CONTEC-SP10-Spirometer-Lung Breathing-Diagnostic (Made in China), to measure ventilatory function test parameters.changes; * Forced expiratory volume in the first second (FEV1); * Forced vital capacity (FVC).; * FEV1/FVC ratio; * Peak expiratory flow rate (PEFR).
chest expansion tests	3 months	Using tape Measurement tool: To measure chest expansion changes in centimetres at the suprasternal notch, at the nipple and xiphoid levels.

Secondary Outcome Measures

Name	Time	Method
craniocervical angle	3 months	• Markings were done with help of Kinovea software. The intersection of a horizontal line passing through C7 spinous process and line joining the midpoint of tragus of ear is known as Craniovertebral angle.
Body mass index	3 months	measuring body mass index kg\\m2 before measuring ventilatory function test by measuring height in centimetres and body weight in kilograms
