A long follow up study of one minute unipedal standing therapy 3 times in a day to prevent femoral neck osteoporosis that have started from 1993 was reported. The registration from July 1993 to March 2004 were 86 cases which measured the femoral neck bone mineral density (BMD) according to dual energy x-ray absorptiometry (DXA) (Hologic QDR 1000 and 2000) in a follow-up period. Average age at starting exercise was 67.9 years old. All cases were female who were registered in our university hospital. The result of unipedal exercise evaluated by the femoral neck BMD was described as follows : The increased cases of BMD were 15/24 (62.5%) post exercise 3 months, 15/37 (40.5%) post 6 months, and 12/21 (57.1%) post one year, 8/25 (32%) post 3 years, 7/13 (53.8%) post 5 years and 1/3 (33.3%) post 10 years. We have no fracture cases in which continued exercise in follow-up period. According to a randomized controlled study of unipedal standing balance therapy to clinically defined high-risk elderly individuals a therapy group reduced fall times by a significant difference than non-therapy group. We conclude that unipedal standing therapy is efficacious against femoral neck osteoporosis and fractures.
