Brief Summary

this study will apply a modified cervical exercise that combined McKenzie's and Kendall's exercises, consisted of neck extension exercises and stretching of the pectoralis muscles at the same time. Although they only required a short time to complete, the exercises proved being effective in improving forward head posture.

Conditions

Chronic Non-Specific Neck Pain

Keywords

Kendell Postural Correction Exercises; McKenzie Postural Correction Exercises; Brachial Plexus Mechanosensitivity; Chronic Non-Specific Neck Pain

Outcome Measures

Primary Outcomes (4)

• Change in Neck pain intensity will be measured with a visual analogue scale (VAS)

  at first week and after 4 weeks of treatment

• Change in Cervical ROM will be measured by CROM

  at first week and after 4 weeks of treatment

• The strength-duration curve to assess the change in mechanosensitivity of brachial plexus

  at first week and after 4 weeks of treatment

• Change in Functional performance will be measured by Neck disability index

  at first week and after 4 weeks of treatment

Interventions

combined Kendell and McKenzie cervical posture correction exercises, ultrasound, hot packs, cervical extensors stretching and strengthening exercise. OTHER

• The combined exercise will be done as follow: 1\) slowly pull the subject's neck to the head, thereby attaching the chin to the neck. (2) the subject's eyes should be looking directly forward. (3) hold both hands on the back of the subject's head. (4) ask the subject to push his/her head backwards against the hands. (5) ask for the hands to be spread as wide as possible in order to stretch the pectoralis major. Therapeutic ultrasound: Moist heat packs: Stretching Exercises: Posture correction exercises training for forward head posture includes stretching of tight muscles such as Pectoralis major, levator scapulae, upper trapezius, suboccipital muscles, sternocleidomastoid Stretching exercises of pectoralis major, levator scapulae, upper fibres of trapezius, suboccipital muscles, sternocleidomastoid Strengthening Exercises Chin Tucks exercise Neck isometric exercises
