Damage to the peripheral nerves and spinal roots in natural anatomical tunnels is not only a common form of damage to the nervous system, but also an important medical and social problem; because tunnel neuropathy and degenerative-dystrophic diseases of the spine are one of the most common reasons for the release of citizens from the call, the dismissal of military personnel from the Armed Forces of the Russian Federation, seafarers, changes in the category of fitness for military service. According to various authors, the combination of compression — ischemic neuropathies with signs of spinal cord lesions occurs in 30–70% of cases of tunnel syndromes. This is especially true for seafarers, because they are more likely to be affected by the musculoskeletal system, as long-term, monotonous load can lead to micro-traumatization and micro-hemorrhage, followed by scarring of muscles, tendons, ligaments, fascia and, as a consequence, the narrowing of natural anatomical tunnels. Revealed the existence of a relationship between the sea and the frequency of lesions of the spine, the shoulder girdle, with the emergence of the syndrome of the rotator cuff and carpal tunnel syndrome. In military personnel, this may occur during excessively long compression of the upper arms during shooting, training, work in low temperatures and vibration.
