Effect of Combined Kendell and McKenzie on Brachial Plexus Mechanosensitivity in Chronic Non-Specific Neck Pain
Condition: Chronic Non-Specific Neck Pain
MeSH terms: Neck Pain
Study type: Interventional

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.
    

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.
    

Intervention name(s): combined Kendell and McKenzie cervical posture correction exercises, ultrasound, hot packs, cervical extensors stretching and strengthening exercise.; ultrasound, hot packs, cervical extensors stretching and strengthening exercise.
Intervention type(s): Other; Other
Intervention description(s): • 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.
