Background

With the change of life and working modes and the popularization of computers and smart phones, more and more people see a doctor due to the symptoms of cervical vertebra discomfort and neck pain, and neck pain is a ubiquitous problem. A large number of researches show that pathological changes of related muscles around the cervical vertebra play a vital role in the occurrence and development of cervical spondylosis. The muscle strength of the muscles around the cervical vertebra is weakened, the dynamic balance system of the cervical vertebra can be damaged, the cervical vertebra can not maintain normal physiological radian, and the curvature of the cervical vertebra is changed. Therefore, the insufficient muscle strength of the neck can be identified in time, the occurrence risk of the cervical spondylosis can be judged in advance, and intervention measures can be taken in early stage. Meanwhile, the cervical muscle strength training is strengthened, the cervical stability is maintained, the degeneration of cervical strain is delayed, and the cervical spondylosis rehabilitation is promoted. Although various cervical vertebra massage physiotherapy instruments are developed, the instruments cannot replace the strength exercise of cervical vertebra muscles, and cannot effectively improve the physiological function state of the cervical vertebra muscles.

SUMMERY OF THE UTILITY MODEL
