Occupationally used high-frequency vibration is supposed to have negative effects on blood flow and muscle strength. Conversely, low-frequency vibration used as a training tool appears to increase muscle strength, but nothing is known about its effects on peripheral circulation. The aim of this investigation was to quantify alterations in muscle blood(More)
OBJECTIVE To define the effects of therapeutic exercise on bone density and back complaints. METHODS A randomised controlled trial with parallel groups was conducted in an outpatient clinic, Medical School, University of Vienna. Ninety two sedentary post-menopausal women with back problems were randomly allocated to either exercise (groups 1 and 2) or(More)
Physical exercise is often recommended as a therapeutic tool to combat pre- and postmenopausal loss of bone density. However, the relationship between training dosage (intensity, duration, frequency) and the effect on bone density still is undergoing discussion. Furthermore, the exercise quantification programs are often described so inadequately that they(More)
BACKGROUND & AIMS Endoscopic screening for sporadic colorectal cancer relies in part on the detection of adenomatous polyps. Nonpolypoid adenomas or flat dysplasia may go unrecognized by conventional endoscopy. This study attempted to develop and test a novel endoscopic method for detecting polypoid and nonpolypoid colonic adenomas. METHODS Colectomy(More)
Peaking in young adulthood, both bone mass and muscle strength decrease with ageing, but bone loss may accelerate after the menopause and can be delayed by estrogen replacement therapy (ERT). This study was designed to evaluate whether, like bone density, the muscle strength was affected by the onset of menopause and/or ERT. First grip strength (GS) of(More)
To evaluate the efficacy of therapeutic exercises in the prevention of bone loss, 146 untrained healthy postmenopausal women were prospectively controlled for (mean +/- SD) 3.0 +/- 1.3 yr. Eighty-two subjects aged (mean +/- SD) 61.5 +/- 6.1 yr participated in an exercise program (group 1) and sixty-four aged (mean +/- SD) 59.1 +/- 7.4 yr served as controls(More)
Osteoporosis is a systemic skeletal disease characterized by diminished bone mass and deterioration of bone microarchitecture, leading to increased fragility and subsequent increased fracture risk. Therapeutic measures therefore aim at reducing individual fracture risk. In Austria, the following drugs, all of which have been proven to reduce fracture risk,(More)
A number of factors with known effects on bone turnover are also immune regulatory factors. Disturbances of bone remodeling thus may be a consequence of altered local immune reactivity. We therefore determined surface markers and intracellular cytokine production of peripheral blood mononuclear cells by four-color flow cytometry in 19 postmenopausal(More)
In a cross-sectional study the effects of several nutritional factors on the manifestations of osteoporosis were investigated in 23 postmenopausal women aged 50 to 70 years. Twelve women (group 1) with osteoporosis and eleven healthy control subjects (group 2) were instructed to keep a seven-day nutritional record. Body mass index (BMI) was recorded, and(More)
We investigated the effects of hormone replacement therapy (n = 27) on biochemical markers of bone turnover in a cross-sectional study of 127 postmenopausal women (according to WHO guidelines 18 patients had normal bone mineral density and 109 suffered from bone loss). Urinary excretion of free deoxypyridinoline and C- or N-telopeptide fragments of type I(More)
