Intervention / Comparator Agent  
Type  Name  Details 
Comparator Agent  Conventional Posture correction and inspiratory muscle training  We are comparing the effect of conventional posture correction and its effect on respiratory function with that of conventional posture correction and inspiratory muscle trainig 
Intervention  Posture Correction and Inspiratory muscle training  Duration:4 weeks With 3 sessions per week. TAPING,MFR AND MCKENZIE EXERCISE (6) Exercise program: 1. Retraction for neck from sitting position 2. Extension for neck from sitting position 3. Lateral bending in head 4. Rotation in head 5. Flexion for neck from sitting position 6. Chin tuck neck from supine position 7. Extension for neck from supine position Kinesio-taping group, two elastic I tapes are used (5 cm wide, 11 cm long). Intervention will be performed three times a week for 4 weeks and participants will be instructed to leave the tape for eight hours after each intervention. POSITION: Sitting on a chair with a neutral position and gazing forward. The tape will be applied in a V shape around the C7–T1 junction MYOFASICAL RELEASE USING LACROSE BALL of upper trapezius, neck extensor, levator scapulae, pectoralis major, minor 15 reps for 3 sets Inspiratory Muscle Training Will be applied for 20 minutes two days of each week, for four weeks. During each IMT session, the participants were asked to maintain diaphragmatic breathing. Each IMT session included five breaths and five sets with 30 seconds between each set.

Brief Summary  

1.      Title :  IMPACT OF POSTURE CORRECTION ON RESPIRATORY FUNCTIONS IN ADULTS WITH FORWARD HEAD POSTURE: A RANDOMIZED  CONTROL STUDY

2. Background/Introduction/Review of Literature: Young adults commonly develop postural deviations such as thoracic hypokyphosis and forward head posture (FHP) due to prolonged screen use. FHP involves upper cervical extension and lower cervical flexion, resulting in altered cervical muscle balance, anterior muscle tightness, and impaired respiratory mechanics including reduced diaphragmatic contraction and thoracoabdominal mobility.

Faulty posture and lifestyle changes contribute to respiratory dysfunction. Studies report that 83% of individuals with posture-related neck pain exhibit altered breathing patterns, indicating a link between cervical posture and respiration.

However, evidence on the effect of postural correction on respiratory function in individuals with FHP remains limited, highlighting a gap in the literature.

 

 

3. Objectives and Hypothesis

·        Primary Objective:

How does postural correction affect respiratory dysfunction associated with Forward head posture?

·        Secondary Objectives:

To study the impact of postural correction on PFT- PEF (Peak Expiratory flow),(FEV1/FVC), Maximal Inspiratory Pressure (MIP), EMG  (upper trapezius, sternocleidomastoid, scalene muscles, neck erector spinae, diaphragm)

 4. Material and Methods

a.      Study Design: Quasi- experimental

b.      Sample size and method: 42,

 Randomized sampling

c.      Enrolment period:

d.      Total Study duration: 6 months post IEC

e.      Inclusion and exclusion criteria:

 

INCLUSION CRITERIA:

·        CVA <50 degree CRA <20 degree

·        Neck Disability Index (NDI)  between 28-45%

·        Age criteria 21-40

·        Male, female

·        Individuals using a smartphone for more than four hours a day who rated their ‘worst pain over the last 24-h’ as moderate using the visual analogue scale (VAS).

·        Use of screen time calculator application in smart phone

 

EXCLUSION CRITERIA

·        Previous history of neck or back surgery ,neurological signs, rheumatoid arthritis, currently using muscle relaxation medication

·        Scoliosis 0f 20 degree or above

·        Cervical trauma, cervical spine surgery, asthma, cancer history, heart disease, uncontrolled hypertension, systemic disorders, smoking history, oral corticosteroids, antibiotics within one  month

f.       Study Procedures:

g.      Assessment tools:

h.        Statistical Analysis Plan (SAP):

·        Independent t-test will be used to calculate the differences in Peak Expiratory flow, Maximal Inspiratory Pressure, FEV1/FVC value and Root Mean Square (EMG) and Chi-square test for categorical data will be done to test the homogeneity of clinical and demographic characteristics of the participants of the experimental and control groups at baseline.

·        Descriptive statistics using mean ± SD or proportion will be done for continuous variables. Median and inter-quartile ranges will be used for categorical data. Shapiro-Wilk test will be used to test the normality of the outcome variables.

·        Independent t-test or Mann Whitney U test will assess between group differences at two time points, baseline, at the end of week 4 depending on the normality of the data.
