Clinical Trial Summary

This study will be conducted to investigate the effect of scapular stabilization exercises on scapular muscles strength (serratus anterior, lower fibers of trapezius, rhomboid major and minor), pain intensity level and kyphosis index in different duration of time using daily of smartphone in smartphone users.


Description:

Modern people use a smartphone along the day, including occupational and leisure activities. Repeated and prolonged use of smartphones affecting muscular activity and strength around the shoulders and upper back especially serratus anterior during maintaining an un ideal posture which may result in the development of postural changes as excessive thoracic kyphosis which in turn will result in inadequate muscles contractions, weakening of postural muscles and fatigue. Scapular muscles strength should be balanced or integrated (muscle balance) and worked in synchronized motion, so, alteration in scapulothoracic motion in resting position or dynamic motion of scapula described as scapulothoracic dysfunction. Muscle imbalances occurs and lower trapezius, serratus anterior and rhomboids muscles are the most common muscles prone to weakness due to exposure to sustained awkward posture or adaptive postures and restriction to specific activity. Continuous use of smartphone for more than 4 hours daily increases shoulder and parascapular pain, fatigue, decrease strength of scapular muscles (lower fibers of trapezius for scapular adduction and depression and rhomboids for scapular adduction and downward rotation) in right dominant side due to prolonged hyperactivity, then weakness.The excessive use of smartphones correlates with increases incidence of vertebral static disorders, especially kyphosis. Scapular stabilization exercises were effective in the early rehabilitation and the balance of both sides of the trapezius with the movement and couple motion of the scapula. It is also effective in increasing muscle activation in the serratus anterior and lower trapezius.

Outcome

Type Measure Description Time frame Safety issue
Primary Assessment of change in scapular Muscles strength To assess the change in scapular Muscles strength by pull push dynamometer (Newton). at baseline and after 4 weeks of intervention
Primary Assessment of change in kyphosis Index To assess the change in kyphosis Index for thoracic spine pre and post scapular Stabilization exercises for smartphone users by flexible ruler. at baseline and after 4 weeks of intervention
Primary Assessment of change in pain intensity level To assess the change in pain intensity level using visual analog scale (scores) (score 0: means no pain & score 10: means highest pain) at baseline and after 4 weeks of intervention
