A Japanese medical association is warning that deterioration in motor functions increases the risk of becoming bedridden or needing nursing care with age.

The Japanese Orthopedic Association, which named the condition Locomotive Syndrome in 2007, has been advocating the importance of exercising and remaining alert for any decrease in physical strength.

Takashi Oe, chief doctor of the orthopedic department at NTT Medical Center Tokyo, said people suffering injuries or diseases related to motor functions are highly likely to develop the syndrome.
