Fragility fractures, or fractures occurring from a low-trauma event, are extremely prevalent among the elderly population worldwide and associated with significant mortality and morbidity. This study evaluated the relationship between FES-I Fear of Falling Survey results, self-reported activity restrictions via the SF-36 survey, and scores recorded by portable, inexpensive clinical assessment tools (CATs) during dynamic functional tasks. Low scores during these tasks may indicate functional deficits that put patients at risk for falls and subsequent fragility fractures...

BACKGROUND: Although the growing popularity of pole dance as a leisure-time activity of people of all ages, the problem of physical effects of exercise on the pole is not considered in the scientific literature. The aim of this study was to evaluate and compare the hand grip strength, body composition and postural stability of fitness pole dancers with different training experience. METHODS: Inclusion criteria were met by 52 female pole dancers. The research program included assessment of body composition (using BC-418 Segmental Body Composition Analyzer Tanita), hand grip strength by hydraulic dynamometer JAMAR, and postural stability using ALFA stabilometric platform...

BACKGROUND: Physical performance and balance declines with aging and may lead to increased risk of falls. Physical performance tests may be useful for initial fall-risk screening test among community-dwelling older adults. Physiological profile assessment (PPA), a composite falls risk assessment tool is reported to have 75% accuracy to screen for physiological falls risk. PPA correlates with Timed Up and Go (TUG) test. However, the association between many other commonly used physical performance tests and PPA is not known...

Spinal neurodegeneration is an important determinant of disability progression in patients with primary progressive multiple sclerosis. Advanced imaging techniques, such as single-voxel (1)H-magnetic resonance spectroscopy and q-space imaging, have increased pathological specificity for neurodegeneration, but are challenging to implement in the spinal cord and have yet to be applied in early primary progressive multiple sclerosis. By combining these imaging techniques with new clinical measures, which reflect spinal cord pathology more closely than conventional clinical tests, we explored the potential for spinal magnetic resonance spectroscopy and q-space imaging to detect early spinal neurodegeneration that may be responsible for clinical disability...

The prolongation of the average life span of women has been associated with the rapidly aging society. However, serious problem have arisen as a result, such as an increase in the number of bed-ridden elderly patients with osteoporosis-associated femoral neck fracture. As preventive measures against osteoporosis for middle-aged to elderly women, 10,000 steps per day and intense exercise have been reported to inhibit bone mineral density (BMD) reduction. However, only a few studies have concretely reported on the type of physical fitness that is effective for BMD in particular parts of the body...

The retinoic acid induced 1 (RAI1) gene when deleted or mutated results in Smith-Magenis syndrome (SMS), while duplication of 17p11.2, including RAI1, results in the dup(17)(p11.2) syndrome characterized by mental retardation, growth and developmental delays, and hyperactivity. Mouse models for these human syndromes may help define critical roles for RAI1 in mammalian development and homeostasis that otherwise cannot be deduced from patient studies. A mouse model for duplication, Dp(11)17+, involving Rai1 has been reported...

UNLABELLED: We conducted a 30-month population-based, randomized, controlled trial in 160 elderly women at risk for fractures on the basis of a low baseline BMD. Mainly home-based weight-bearing exercise was effective in improving strength, balance, and gait. INTRODUCTION: Evidence on the effect of exercise on extraskeletal risk factors for hip fractures comes mainly from studies in voluntary low-risk women, and no population-based, long-term interventions have been performed in elderly women with low bone mass...

Farmworkers experience many work-related hazards, including exposure to neurotoxicants. We compared neurobehavioral performance of 288 farmworkers in central Florida who had done farm work for at least 1 month with 51 controls who had not. Most of the farmworkers had worked in one or more of three types of agriculture: ornamental ferns, nurseries, or citrus fruit. We collected information on farm work history in a structured interview and evaluated neurobehavioral performance using a battery of eight tests...

Recent animal studies have given evidence that vibration loading may be an efficient and safe way to improve mass and mechanical competence of bone, thus providing great potential for preventing and treating osteoporosis. Randomized controlled trials on the safety and efficacy of the vibration on human skeleton are, however, lacking. This randomized controlled intervention trial was designed to assess the effects of an 8-month whole body vibration intervention on bone, muscular performance, and body balance in young and healthy adults...

The object of this article was to determine the predictive value of risk factors for recurrent falls and the construction of a fall risk model as a contribution to a mobility assessment for the identification of community-dwelling elderly at risk for recurrent falling in general practice. The design was a prospective cohort study (n = 311). There were four primary health care centers. A sample stratified on previous falls, age, and gender of community-dwelling elderly persons aged 70 years or over (n = 311) was taken from the respondents to a mail questionnaire (n = 1660)...

We report test-retest reliabilities for a battery of tests (vision, hearing, vibration sense, proprioception, forced expiratory volume, blood pressure, grip strength, and sway) shown previously to predict functional age. Fifty women aged 60 to 86 were retested on the battery after 3 months. All tests except proprioception and blood pressure had reliabilities between .70 and .94. We conclude that the battery provides reliable measures of sensory, motor, and physiological variables which may be used as markers of biological aging in psychological research...
