About this study
Official title: Effect of Combined Kendell and McKenzie Postural Correction Exercises on Brachial Plexus Mechanosensitivity in Chronic Non-Specific Neck Pain
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.
Read the detailed description
Nowadays, neck pain is predictable among people of all ages, whether it is a golden-ager, juvenile, or a schoolchild. In any stage of life, a person may experience neck pain because of the poor posture and prolonged use of electronic devices. Students spend about 80% of their daily life in college and performing various activities in their college, like slouching over computers and laptops for long periods for their college projects, backpacks over one shoulder (laptop bag), and squeezing into chairs or desk, etc. All are posture ruining activities that every student perform daily
When there is no traumatic injury, poor posture is the main root of neck pain. Bad posture results with the functional deviation from the normal aligned posture without any structural changes in the spine or lower extremities (Saxton, 1993). In reflection, muscle weakness and muscular imbalance of the musculoskeletal system leads to the postural deformities that coincide with muscle findings. Continuous load on the neck leads to disc collapse or degenerative changes in the future.
Several studies reported the effect of cervical postural correction exercises on pain, ROM and cranio-cervical angle in patients with chronic non-specific neck pain. Few studies have been concerned with measuring mechanosensitivity as an indicator technique of the effect of different modalities on chronic non-specific neck pain. With the proposal of the combined Kendall and McKenzie exercise program for patients with chronic non-specific neck pain secondary to forward head posture deviations recently, it is important to document how could this new combined technique impact neck posture as well as neural tissue sensitivity and function.
The outcome of this study will provide necessary information to clarify the effect of combined Kendall and McKenzie exercise program on mechanosensitivity and peripheral nerve excitability, pain intensity and cervical range of motion. This study may help and add to the physiotherapists exercise protocol for patient with chronic non-specific neck pain.

- The combined exercise will be done as follow:
- 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.
