Strengthening and Stretching Exercise to Improve Forward Head Posture and Rounded Shoulders

Study Overview
=================
Brief Summary
-----------------
Forward head posture (FHP) and Rounded shoulders (RS) are defined as protrusion of the head and shoulders in the sagittal plane. Forward head posture is defined as the anterior positioning of the cervical spine. Rounded shoulders also called protracted shoulder (PS) is a protrusion of the acromion of the shoulder joint relative to the centerline of gravity of the body, causing stooped posture along with elevation, protraction, and downward rotation of the scapula, and an increased angle between the lower neck bone and upper spine. Many Physical therapy treatment options are available to correct forward head posture and rounded shoulders which focused to correct the muscle imbalance and restore the normal posture of Cervical spine and shoulder. The objective of this study is to compare the outcomes of Strengthening exercise with the outcomes of stretching exercise on the targeted muscle group to correct forward head posture and rounded shoulders. The study will determine effective management plan for correction of forward head posture and rounded shoulders. It will be Experimental Randomized Controlled Trial. 26 Patients will be included through consecutive sampling, with 13 patients in each of 2 groups. Subjects will be equally distributed to two groups with use of dice roll method of randomization. From the two groups, one receiving strengthening exercise treatment and other receiving stretching exercise treatment. Statistical Package for Social Sciences (SPSS) V 25.will be used for Data analysis. Results will be extracted. Conclusion will be made after comparing the pre and post treatment results of both treatment approaches.

Detailed Description
-----------------
Forward head posture and Rounded Shoulder are related to muscle imbalance, which disturbs length tension relationship of muscles. Weak and lengthened muscles in Forward head posture and rounded shoulders are deep neck flexors which include longus capitis and longus coli and weak scapular stabilizers and retractors which include Rhomboids and middle, lower trapezius, Teres Minor and Infraspinatus. The overactive and shortened muscles participating in Forward head posture and Rounded shoulders are Deep upper cervical extensors which include longissimus capitis, Splenius Capitis, Cervical Multifidus, Upper Trapezius and Shoulder protractors and elevators which include Pectoralis minor, Pectoralis major and Levator Scapula. Previous researches suggests that weakened postural muscles should be strengthened and shortened muscles should be lengthened in order to improve postural alignment and alleviate Forward head posture and restoring the normal muscle balance between opposing muscle groups (agonists and antagonists). The majority of treatments have focused on the deep neck flexors, as they play a major role in stabilizing the alignment of the cervical spine. Exercise improved the forward head and Rounded Shoulder significantly. The selection of 50º as a reference angle for forward head posture was guided by previous studies, with the latter reporting 55.02 ± 2.86 as a normal range. As is well known, subjects with forward head posture have a significantly smaller cervical angle when compared with normal subjects. In the present study, the investigators considered 52º as the reference angle based on a previous study which evaluated 310 participants in a standing position and reported 2.6º±15.3 as a normal range, and Brink et al, who evaluated 15 to 17 year-olds and reported a mean shoulder angle value of 51.35º ± 17.2º, and based on the premise that subjects with protracted shoulder have a significantly smaller shoulder angle when compared with normal subjects. Individual will be considered to have rounded shoulder if the angle will be less than 52º.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Strengthening exercise treatment<br>This exercise targets the deep flexor muscles of the upper cervical region the longus capitis and longus colli muscles. | Other: Exercise<br>* Different type of exercises for treatment of Forward Head Posture<br>|
| Active Comparator: Stretching exercise treatment<br>The subject's forearm is stabilized by a vertical plane before the trunk is rotated in the opposite direction. Therefore the arm on the involved side is externally rotated and abducted to 90. | Other: Exercise<br>* Different type of exercises for treatment of Forward Head Posture<br>|
