Introduction
Breathing is a natural physiological process. It helps to inhale oxygenated air and exhale deoxygenated air from the body. The lungs are the primary organ related to breathing and respiration. Along with this, the neck, trachea, and respiratory muscles play a crucial role in maintaining the breathing process. A normal breathing process is evaluated by its patterns. However, in certain cases, an abnormality in the breathing patterns can be seen.
What Is Neck Pain?
Pain in the neck and its surrounding region is known as neck pain. Such pain is usually felt in the back and side portions of the neck. According to the definition put forward by the International Association for the Study of Pain, neck pain can be experienced in any region of the back part of the neck, stretching from the upper nuchal line (a point where muscles attach to the temporal bone) to the first spinous process of the thoracic spine. Musculoskeletal impairment in the neck region is the primary causative factor of such pain. According to research, it ranks as the fourth most common cause of disability worldwide. Approximately 30 percent of the world's population is affected by this ailment.
Types:
Sudden and rapid onset of neck pain with no previous history is known as acute neck pain. Persistent neck pain in a particular area for a longer period is known as chronic neck pain. Axial neck pain refers to the pain that is experienced in the cervical spine area or the back portion of the neck. Such pain extends to the shoulders. On the other hand, radicular pain is a type of neck pain that spreads to various parts of the hand and head. This particular pain can be upper cervical spinal pain that originates from the area above the fourth cervical vertebrae. Typically, this pain radiates to the back of the head. In the lower cervical area, the pain usually originates between the fourth and seventh vertebrae. It commonly radiates to the lower back, hand, and upper chest region.
Causes:
Several factors can lead to this condition. One of the primary causative factors linked to it is the weakening of muscles due to overuse. Prolonged sitting in the same position, along with poor posture while working, sleeping, driving, and walking, may also play a role in some instances. Muscle overstretching and damage to muscle fibers are caused by such conditions. Degenerative changes in the cervical vertebrae due to wear and tear are another significant factor for muscle pain. Excessive wear and tear in the cervical vertebrae can result in the development of bone spurs along the edges of the vertebral bodies, leading to nerve and spinal disc compression. Consequently, patients may experience intense pain due to nerve fiber compression. Cervical spondylosis is often caused by osteoarthritis. Trauma or sudden postural changes can also result in injury in some cases. vertebral canal narrowing and abnormal disc positioning can contribute to this condition. In milder cases, these changes may be due to degenerative alterations in the vertebral body. Hormonal fluctuations, age-related changes, trauma, and postural influences can also be factors. Compression on the cervical nerve and spinal cord is often associated with these issues.
What Is Breathing Pattern Disorders?
Breathing pattern disorder or dysfunctional breathing is a type of abnormal breathing. In this condition, a change in the breathing pattern is seen, which is associated with an alteration of the depth and rate of breath. This condition is characterized by impairment in the gas exchange functioning of the lungs and mechanical restriction in breathing. Such a condition involves an elevation in either the respiratory rate, tidal volume (total amount of air that moves in or out from lungs during respiration), or both.
Such a condition is often related to stress, depression, anxiety, a change in altitude, and hormonal changes. Also, lung disorders like asthma, chronic obstructive lung disease, and pneumonia are related to such conditions.
What Is the Correlation Between Neck Pain and Breathing Pattern Disorder?
The correlation between chronic neck pain and breathing pattern disorder is not established yet. According to many researchers, there is no correlation between chronic neck pain and breathing pattern disorder. However, according to modern researchers, there are certain physical changes seen in patients suffering from chronic neck pain;
-
In patients suffering from chronic neck pain a reduction in the lung functional capacity is observed. A reduction in the vital capacity, inspiratory capacity, expiratory reserve volume, and forced expiratory volume is observed in such patients.
-
Chronic neck pain is related to abnormal functioning of the cervical musculature. Such abnormal functioning also affects the breathing process. As a result, respiratory muscles do not function properly. Additionally, features like cervical spondylitis may cause abnormal positioning of the respiratory muscles. All these factors lead to the generation of low pressure during the respiratory process. On examination, maximal inspiratory and expiratory pressures are observed.
-
Alteration in the breathing pattern in such cases is seen. Forced breathing patterns lead to the activation of muscles like sternocleidomastoid and other associated muscles. Therefore, the lack of proper activation in these muscle groups and issues related to excessive activity and weakness prevent their ability to effectively engage during the inhalation process. Vertically elevating the sternum when breathing in, as opposed to expanding horizontally and developing deep clavicular grooves due to prolonged elevation of the clavicles, represents incorrect breathing techniques. These faulty patterns may arise from bilateral overuse of the trapezius, anterior scalene, and sternocleidomastoid muscles.
-
Hyperventilation or abnormal deep breathing is a common feature in patients suffering from chronic neck pain. It is associated with neck muscle strength, neck flexor, and endurance. As a result, there is low pressure of carbon dioxide in the blood and alveolar spaces.
Conclusion
Neck pain is a very common complication. It is often caused by injury to the neck muscles which causes overstretching and damage to muscle fibers. Also, a change in the vertebral architecture may be related to such complications. All these factors lead to abnormal positioning and functioning of the respiratory muscles. As a result, abnormal lung functioning and breathing patterns are observed. This leads to breathing difficulties and a change in the level of oxygenation in the blood.
