Brief Summary

The purpose of the clinical trial is to investigate the effect of the combined Kendall and scapulothoracic exercises program on mechanosensitivity of brachial plexus, cervical range of motion, neck functional ability, and craniovertebral angle in patients with chronic non-specific neck pain. we have 3 groups to compare between traditional treatment, scapulothoracic and kendall exercises in treatment of chronic non-specific neck pain.

Conditions

Non-specific Chronic Neck Pain

Keywords

chronic non-specific neck pain; Kendall exercises; Scapulothoracic exercises; Brachial Plexus mechanoreceptors

Outcome Measures

Primary Outcomes (1)

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

  The mechanosensitivity of brachial plexus will be measured with strength duration curve by EMG. Assessment will be before and after treatment

  at first week and after 4 weeks of treatment

Secondary Outcomes (3)

• Change in Cervical range of motion

  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

• Change in Craniovertebral angle

  at first week and after 4 weeks of treatment

Study Arms (3)

Group A will receive conventional treatment

EXPERIMENTAL

Other: Conventional treatment program

Group B will receive scapulothoracic exercises and conventional treatment.

EXPERIMENTAL

Other: Conventional treatment program; Other: Scapulothoracic exercises

Group C will receive Kendall exercises, scapulothoracic exercises and conventional treatment

EXPERIMENTAL

Other: Conventional treatment program; Other: Scapulothoracic exercises; Other: Kendall exercises

Interventions

Conventional treatment program OTHER

Ultrasound, hot packs, cervical postural stretching and strengthening exercise will be done for all groups. Stretching Exercises Posture correction exercises training will include stretching of tight muscles such as Pectoralis major, levator scapulae, upper trapezius, suboccipital muscles and, sternocleidomastoid. Strengthening Exercises Exercises will include Chin Tucks exercise and Neck isometric exercises

Group A will receive conventional treatment; Group B will receive scapulothoracic exercises and conventional treatment.; Group C will receive Kendall exercises, scapulothoracic exercises and conventional treatment

Scapulothoracic exercises OTHER

Scapulothoracic exercises It is a strengthening exercises of the serratus anterior muscle, as well as the middle and inferior fibres of the trapezius muscle

Group B will receive scapulothoracic exercises and conventional treatment.; Group C will receive Kendall exercises, scapulothoracic exercises and conventional treatment

Kendall exercises OTHER

The exercise techniques used by Kendell were as follows: 1\. Stretching of the Cervical Extensors: By sitting with the head down and putting both hands across the occipital area, the cervical extensors can be stretched by adopting a flex neck position 2- Strengthening of the Deep Cervical Flexors Positioning supine with the chin tucked in and lifting the head for 2 to 8 s 3- Strengthening the Shoulder Retraction Maintaining an upright posture, keep the resistance band circling with strong support and stretching it with the upper limbs of both sides so that there is full retraction of the scapula 4-Stretching the Pectorals muscle Assigning both hands on the occipital area and pulling the elbows back up (bilateral) and performance arm abduction and external rotation (unilateral).

Group C will receive Kendall exercises, scapulothoracic exercises and conventional treatment
