OBJECTIVE To investigate the effects of 21 weeks' progressive strength training on neuromuscular function and subjectively perceived symptoms in premenopausal women with fibromyalgia (FM). METHODS Twenty one women with FM were randomly assigned to experimental (FM(T)) or control (FM(C)) groups. Twelve healthy women served as training controls (H(T)). The FM(T) and H(T) groups carried out prog...

OBJECTIVE To review the scientific literature concerning the classification of fibromyalgia (FM), including previous studies focusing on the gnosologic evaluation of FM, with the aim of proposing a classificatory hypothesis based on the current scientific evidence. METHODS Systematic review using a baseline MEDLINE search. Search terms included «fibromyalgia» and «classification». Additional ...

STUDY OBJECTIVES To investigate the prevalence of restless legs syndrome (RLS) in fibromyalgia (FM) and determine the presence and amount of sleep disruption in FM patients with RLS. RLS and FM have been associated in uncontrolled studies using a variety of RLS definitions. We explored this relationship using a cross-sectional study design. METHODS FM cases that met the American College of Rh...

OBJECTIVE To examine associations between regional fat mass (FM) distribution and cardiometabolic risk factors among ethnic minority groups, such as non-Hispanic blacks and Hispanics. DESIGN AND METHODS The associations among 8,802 US residents who participated in the 1999-2004 US National Health and Nutrition Examination Survey were examined. Body composition was measured using dual-energy X...

In our daily life, we are successively exposed to frequency-modulated (FM) sounds that play an important role in speech and species-specific communication. Previous studies demonstrated that repetitive exposure to identical pure tones resulted in decreased neural activity. However, the effects of repetitively presented FM sounds on neural activity in the human auditory cortex remain unclear. In...

Animal and human studies suggest that directional categorization of frequency-modulated (FM) tones (rising vs. falling) is a function of the right auditory cortex (AC). To investigate this hemispheric specialization in more detail, we analyzed both the binaural and monaural representation of FM tones and the influence of contralateral white noise on the processing of FM tone direction. In two f...

The present a novel class of multidimensional orthogonal FM transforms. The analysis suggests a novel signal-adaptive FM transform possessing interesting energy compaction properties. We show that the proposed signal-adaptive FM transform produces point spectra for multidimensional signals with uniformly distributed samples. This suggests that the proposed transform is suitable for energy compa...
