A method to protect the hips during falls could effectively reduce the incidence of hip fractures. We report the results of the first hip protector trial in Japan, performed between July 1996, and September 1999. One hundred and sixty-four elderly female residents of nursing homes, with Activities of Daily Living above the wheelchair level, agreed to(More)
Transforming growth factor-beta (TGF-beta) is both abundant in bone and an important regulator of bone metabolism. A T-->C transition at nucleotide 29 in the signal sequence region of the TGF-beta1 gene results in a Leu-->Pro substitution at amino acid position 10. The possible association of this polymorphism with bone mass and the prevalence of(More)
BACKGROUND The objective of this review was to summarize findings on aquatic exercise and balneotherapy and to assess the quality of systematic reviews based on randomized controlled trials. METHODS Studies were eligible if they were systematic reviews based on randomized clinical trials (with or without a meta-analysis) that included at least 1 treatment(More)
OBJECTIVES Although the importance of stretching exercise for pain-relieving and patient education is well documented for chronic lumbago patients, it is uncertain how effective on-the-job training (OJT) is for female caregivers in nursing homes. In the present pilot trial based on multicenter randomization, we evaluated the intervention effect of a lecture(More)
OBJECTIVE To test the working hypotheses that after a brief (10 min) intervention, (a) young adults can volitionally reduce fall-related wrist impact forces, and (b) no difference in impact force would exist between intervention and control groups at 3-weeks or 3-months follow-up. BACKGROUND The wrist is the most commonly fractured site in the body at any(More)
OBJECTIVE To examine the possible relationship between a T-->C polymorphism at nucleotide position 29 of the transforming growth factor beta1 (TGFbeta1) gene and genetic susceptibility to radiographic spinal osteophytosis. METHODS A total of 540 postmenopausal Japanese women were subjected to radiography of the spine and determination of bone mineral(More)
OBJECTIVE To summarize the evidence for curative and health enhancement effects through forest therapy and to assess the quality of studies based on a review of randomized controlled trials (RCTs). STUDY DESIGN A systematic review based on RCTs. METHODS Studies were eligible if they were RCTs. Studies included one treatment group in which forest therapy(More)
AIM To summarize the evidence from randomized controlled trials (RCTs) on the effects of horticultural therapy (HT). METHODS Studies were eligible if they were RCTs. Studies included one treatment group in which HT was applied. We searched the following databases from 1990 up to August 20, 2013: MEDLINE via PubMed, CINAHL, Web of Science, Ichushi-Web,(More)
Although vitamin D improves bone mineral density 0.66% per year at spine site and 1.23% per year at femoral neck site, respectively, vitamin D is useful for preventing osteoporotic fractures, especially hip fractures in the elderly. Vitamin D affects microstructure and bone turnover for osteoporotic bone to become strong bone. And vitamin D improves muscle(More)
Among seniors with osteoporosis, falls can cause devastating injuries such as hip fractures even with only weak impacts. We have begun a combined medical examination and educational program for exercise to prevent injurious falls. To make fall prevention practices more widespread, we hold one-day simplified fall prevention program and instruction courses(More)
