據(jù)統(tǒng)計長期從事打電腦、低頭、職業(yè)司機和體力勞動工作人員80%以上的人都不同程度地有頸椎退行性生理病變，原因是長期處於高負荷甚至是超負荷狀態(tài)下就容易發(fā)生退行性病變，例如頸椎生理曲度變直，頸椎間盤突出，頸椎間盤狹窄，以及骨質(zhì)增生等病癥。導致、頭暈、耳嗚、手指麻木、頸肩酸痛僵硬等癥狀，奧達力頸椎牽引器對頸肩的各種不適癥狀有著明顯的改善作用，是根據(jù)物理學理論的原理和動力學的原理利用人體自身的重力來達到牽引效果，是一種安全、實用，使用方便的家庭物理運動產(chǎn)品，原理是使頸椎在正常的生理曲線狀態(tài)下實現(xiàn)柔性的牽引。使頸椎間隙逐漸被拉開，使正常的頸椎保持健康狀態(tài)，使病變的頸椎得到恢*，頸肩不適的癥狀得到緩解，同時利用舒展器上的按摩點刺激相應的穴位來達到預防保健的作用是現(xiàn)代都市家庭必備的保健產(chǎn)品。

According to statistics, 80% of the people who perform computer-intensive work, head-bending work, driving or physical labor, more or less have some form of cervical spondylopathies. If the neck is under high or extreme pressure for an extended time, it is prone to develop cervical spondylopathies, such as the straightened physio-curve, slipped disc, narrowed disc space and bone spurs, etc. The symptoms are headache, dizziness, tinnitus, finger stiffness, sore and stiff neck and shoulder, etc. The OTARI Neck Stretcher is designed based on the theories of kinetics. It is a safe, practical and easy to use family physical exercising device and has a significant effect on improving various kinds of neck and shoulder discomforts. The weight of the human body is used in the mechanism of the Stretcher to create a soft traction on the neck when it is at its normal physio-curve to maintain the healthy condition of the neck. The space between the discs is slowly stretched in order to heal spondylopathies and relieve neck and shoulder discomfort. At the same time, the massage points on the Stretcher can stimulate respective points on the body in order to achieve healing and revitalizing effects. It is a health device for any modern household.
