Official title: Effects of Cranio-cervical Flexion Training on Cervical Proprioception in Patients With Mechanical Neck Pain

Status Completed

Clinical Trial Summary

To determine the effects of cranio-cervical flexion training on the cervical proprioception and pain in patients with mechanical neck pain.

Clinical Trial Description

Neck pain is a very common health related problem that alters an individual's daily life. In the over-all population and musculoskeletal training, it happens next to low back pain in its frequency. Neck pain has a point incidence of approximately 13% and a lifetime incidence of almost 50%. It is a joint reason for visits in accidents and emergency departments. Neck pain is said to be more common in females than in males and it crests at the middle age. Sedentary lifestyles are contributing to the occurrence of neck pain. Chronic neck pain affects a very significant number when it comes to the adult population. Proprioception involves the body sensations that helps in the proper orientation of the body relative to the movement of joints and bones, in rest and in motion. When the joint position sense is disturbed due to some kind of abnormality, a person adopts an abnormal posture. If this faulty posture continues, this causes abnormalities in the spine and causes impaired stability. The system of proprioception in our body is dependent upon different afferent stimulus reaching towards mechanoreceptors from afferent neurons. Due to the presence of high densities of muscle spindles in the slow twitch fibers in deep, small intrinsic dorsal and sub-occipital muscles play very important role in the control of posture. The cervical musculature has a number of other systems working in congregation including vestibular system, visual as well as central nervous system feedbacks. All of these systems send the signals according to the body and head movements. That is why, the involvement of upper cervical region can cause impaired proprioception and altered afferent stimulus. When many levels of nervous system gets involved, it can impact a change in the sensitivity of muscle spindle and causes one of the major proprioception shortages in cervical patients. For the maintenance of motion, posture and joint position, proprioceptive information has an important role and any factor that disrupts this information may be considered a major reason of incorrect motion patterns and symptoms of chronic recurrent pain. Cranio-Cervical flexion training which aims to enhance activation of the Deep Cervical flexors (DCFs) and restore coordination between the deep and superficial cervical flexors, is one form of exercise that has been advocated for addressing impaired neuromuscular control of the cervical flexors. Clinical trials examining the effectiveness of this exercise regime have demonstrated positive outcomes in terms of decrease in neck pain and disability, improvement in sitting posture, enhanced neuromuscular control of the cervical flexors in patients with chronic neck pain and also improved proprioceptive acuity of the neck, indicating that proprioception can be enhanced with specific exercise. Cranio-cervical flexion training will be done using Pressure Biofeedback Device by Chattanooga. A cervical range of motion (CROM) device will be used to assess cervical proprioception. The unit of CROM has three inclinometers attached to it and each inclinometer collects degree of movement in each plane. The CROM device has an advantage over the use of a single inclinometer that it does not have to be moved again to measure the degree of movements in other planes. One the CROM device is mounted on the patient's head, instructions are given to the patient regarding their neutral head movements and target head movements. After that, patient is blindfolded and all the movements are performed with patient being blindfolded. No feedback should be given during the ongoing session. This entire procedure takes around 15 minutes for one individual. In the light of previous research works, the disturbances in the proprioception involving cervical spine are a very important factor in treating the patients with neck pains. It is very important for a physical therapist to address these deficits and stop the vicious cycle of pain as well as improve proprioception. So, this study is aimed at improving the proprioception and decreasing mechanical neck pain with the help of deep cervical muscles flexion training using pressure biofeedback device. ;
