Global Postural Re-education in Text Neck Syndrome

This study was conducted in the research laboratory section, Faculty of Physical Therapy, Cairo University. The purpose of the current study was to investigate the effect of global postural reeducation on neck pain intensity, neck disability craniovertebral angle, shoulder angle, cervical range of motion, and cervical proprioception in individuals with text neck syndrome.

This study is a Pre- test post- test single blind randomized controlled trial. • Subjects' selection:

A. Participants:

• 60 Participants from both genders diagnosed by physician as TNS
• Their age ranging from 18-44 years old
• Their body mass index ranging from (18-30) Kg/m2
• Their using mobile phones for more than 3-4 hours per day was assessed by using The Arabic version of the smartphone addiction scale
• Informed consent (Appendix I) attained from each participant after clarifying the scope and purpose of the research and ensuring them of their right to decline at any time and of the privacy of any information obtained.

B- Sample size:

The sample size was calculated using the G*Power software (version 3.0.10). F-test MANOVA within and between interaction effects was selected. Considering a power of 0.80, an α level of 0.05 (2 tailed) and effect size of 0.37; two groups and number of measurements two, a generated sample size of at least 60 subjects,30 subjects per group was required.

C. Randomization:

Concealed allocation was performed by an independent person who not involved in either recruitment or treatment of the patients. He used individually, sequentially numbered index cards containing the randomly assigned intervention groups (A and B) that folded and placed in sealed, opaque envelopes. the researcher opened the envelope before the 1st session and proceeds with the treatment on the initial examination day according to the group assignment.

D. Groups:

Participants assigned at random into 2 equal groups. Control group (A) received conventional treatment only. Experimental group (B) received Global postural reeducation in addition to conventional treatment E. Incluction critrria
