PURPOSE : As demanded by the present situation, the "Falls Prevention program" has been carried out in Japan as a national policy. At present, it is considered to symbolize its idea and significance of the health promotion. The purpose of the present study was to examine how the program influenced the mobility parameters one year or more after the end of the program. RELEVANCE : Dargent-Molina [1999] reported that the walking ability (10m-rapid gait time and cadence) related to rate of falls and bone fracture. Therefore, in the program, training for improving mobility walking ability is a main part. DESCRIPTION : 169 female middle and aged subjected, subjects completed 12 weeks falls prevention program, were recruited. In the present study, the maximum walking speed for 10-meters, the maximum step length, 40-cm steps and single leg stance were assessed as mobility parameters. Quantitative ultrasound bone measurements (AOS100, Aloka Co. Ltd, Tokyo, Japan) were used to calculate the Osteo Sono-Assesment Index (OSI) of the calcaneus which is an indicator of the bone mass. The mobility parameters and the bone mass were measured at the end of the program and at one year or more after completion of the program. EVALUATION : Subjects were 169 women and 22 men who had completed twelve weeks program, for Falls Prevention. In the present study, the maximum walking speed for 10-meters, the maximum step length, 40-cm steps and single leg stance were assessed as mobility parameters. Quantitative ultrasound bone measurements (AOS100, Aloka Co. Ltd, Tokyo, Japan) were used to calculate the Osteo Sono-Assesment Index (OSI) of the calcaneus which is an indicator of the bone mass. The mobility parameters and the bone mass were measured at the end of the program and at one year or more after completion of the program. CONCLUSIONS : It was found that the calcaneal bone strength did not decrease in the subjects whose mobility parameters were better than normal at the end of program period. Since walking is practical and easy exercise to practice and its ability might be a reliable indicator for estimating the risk of falls, improving the walking ability is considered to be a good strategy to prevent falls and bone fracture. IMPLICATIONS : Since maintenance of high mobility parameters influences the calcaneal bone mass, compliance of a habit to exercise regularly seems to be important. Therefore, an educational system encouraging maintenance of the habit for life should be constructed for the community-dwelling peoples.
