Locomotive syndrome in Japan

The present aging rate in Japan of some 28% will continue to increase along with the advancing age of elderly persons. Therefore, the demand for care will also increase. Approximately 25% of the need for nursing-care defined by the Japanese long-term care insurance system is associated with disorders or deterioration of locomotive organs. Therefore, the prevention and treatment of diseases in the locomotor system and maintenance of motor function are important for extended healthy life span and to decrease the demand for long-term care. Based on this background, the Japanese Orthopaedic Association (JOA) proposed the concept of locomotive syndrome (LS) in 2007, which is defined as reduced mobility due to impaired locomotive organs. Changes in locomotion must be noticed early to ensure the timely implementation of appropriate checks and measures of locomotion can uncover risk of acquiring LS. The acquisition of an exercise habit, appropriate nutrition, being active and evaluating and treating locomotion-related diseases are important to delay or avoid LS. The JOA recommends locomotion training consisting of four exercises to prevent and improve LS. Countermeasures against LS should become a meaningful precedent not only for Japan, but for other countries with rapidly aging populations.
