While podobarometric techniques have been applied to the study of pressures in Hallux Valgus (HV), little is known about its clinical and radiological determinants. So, the aim of the present study was to determine the plantar pressure pattern in participants with mild HV, comparing to a control group, and their clinical and anthropometric determinants.(More)
Mild hallux valgus (HV), which can lead to alteration of the plantar pressure pattern with an overpressure under the hallux, can be repaired percutaneously. Our goals were to determine whether the percutaneous distal soft tissue release (DSTR)-Akin procedure restores the loading pattern and to evaluate which are the determinants of the measures of(More)
OBJECTIVE To determine bone mass using quantitative phalangeal bone ultrasound in institutionalized schizophrenic patients under chronic treatment with antipsychotic drugs. METHODS A total of 73 patients with schizophrenia (25 women, mean age 59.84 +/- 17.01 years; 48 men, mean age 61.89 +/- 12.95 years) and 73 healthy subjects (25 women, mean age 60.37(More)
OBJECTIVE To study the effect of beer consumption on bone mass in a group of healthy women, by using phalangeal bone ultrasound to evaluate the amplitude-dependent speed of sound. METHODS This was a cross-sectional study of 1697 healthy women (mean age 48.4 y, body mass index (BMI) 19.0-32.0 kg/m(2)), recruited in a clinical convenience sample and(More)
BACKGROUND Stroke is a major public health problem. OBJECTIVE To use the Barthel Index to evaluate basic activities of daily living in stroke survivors and detect any predictors of functional outcome at 6 months after stroke. METHODS In an observational longitudinal study, data were gathered on consecutive patients admitted to the comprehensive stroke(More)
The purpose of this study was to: (a) determine the relationship between quantitative ultrasound (QUS) results and anthropometric, dietary and body composition factors and establish reference ranges for amplitude-dependent speed of sound (Ad-SoS) in the phalanges and broadband ultrasound attenuation (BUA) in the calcaneus of children from Extremadura,(More)
The purpose of this study was to assess the effects of chronic oral anticoagulant (OAC) treatment on bone mass using quantitative ultrasound (QUS) techniques. A total of 120 patients (47 women and 73 men) undergoing treatment with OAC and 57 healthy subjects (27 women and 30 men) participated in this study. Bone status was assessed using QUS devices that(More)
The moderate consumption of fish is recommended for a healthy diet and is also a feature of the Mediterranean diet. Fish is a major food group in diets throughout the world, and studies show that fish consumption is associated with a lower risk of a number of conditions. Spain has one of the highest annual per capita consumptions of fish worldwide. As fish(More)
OBJECTIVE Nutritional factors, especially the two essential nutrients calcium and vitamin D, have been shown to play an important role in bone health. We wanted to determine the possible protective effect of calcium intake in adequate amounts on bone mass as assessed by quantitative ultrasound in postmenopausal women who also have a high intake of selenium.(More)
