BACKGROUND AND PURPOSE Sensory evaluation is fundamental to evaluation of patients with Carpal Tunnel Syndrome (CTS). The purpose of this study was to determine the construct validity and responsiveness for sensory threshold tests in patients with CTS. METHODS Sixty-three patients diagnosed with CTS were evaluated prior to orthotic intervention and again at follow up at 6 and 12 weeks. Sensor...

AIMS (1) To determine the pulpal sensory thresholds in human teeth obtained from using various EPT conducting media and (2) to determine whether there are gender differences. METHODOLOGY One intact maxillary central incisor was randomly selected from each of 40 participants (20 male, 20 female) aged 19-24 year. A constant-current electrical stimulator (University of Bristol, UK) was used to a...

INTRODUCTION A normal sexual response in the female depends on the integrity of afferent sensory input from the genital region. So far genital sensation has been investigated only during a non-excitatory state, and the sensory physiological changes, which occur during the sexual cycle in this region, are still obscured. AIM To investigate the sensory status of the female genital region during...

Young and elderly subjects yielded forced-choice detection thresholds in each of seven sensory tasks: (1) taste of sodium chloride, (2) smell of butanol, (3) cooling, (4) low-frequency vibrotaction, (5) high-frequency vibrotaction, (6) low-frequency hearing, and (7) high-frequency hearing. Average scores across these tasks nearly perfectly separated the 22 elderly from the 15 young subjects. Fo...

Introduction.   Subcutaneous, occipital nerve stimulation has emerged as a potentially effective treatment modality for patients with refractory headache disorders. The purpose of this study was to document occipital stimulation characteristics in 10 patients status post implantation of an occipital nerve stimulator. Methods.   All possible electrode combinations were tested in each patient, an...

BACKGROUND Many patients with irritable bowel syndrome (IBS) have lowered sensory thresholds to rectal distention when compared to control subjects, a phenomenon called visceral hypersensitivity. AIM To investigate the usefulness of a rectal barostat as a diagnostic tool in IBS and if there are differences in visceral hypersensitivity in different groups of IBS patients. PATIENTS AND METHOD...

BACKGROUND When steady fixation is maintained on the centre of a large patch of texture, holes in the periphery of the texture rapidly fade from awareness, producing artificial scotomata (i.e., invisible areas of reduced vision, like the natural 'blind spot'). There has been considerable controversy about whether this apparent 'filling in' depends on a low-level or high-level visual process. Ev...

The role of sex and gender in accounting for individual pain behaviors is poorly understood. The present study was conducted to determine whether neonatal nociceptive stimuli at postnatal day 1 (PD1) in rats would lead to a differential behavioral impact based on gender. Animals were divided in 4 groups according to treatment (two injections of 4% formalin into the pad of right paws at PD1 or c...

Many recent studies show that the human brain integrates information across the different senses and that stimuli of one sensory modality can enhance the perception of other modalities. Here we study the processes that mediate cross-modal facilitation and summation between visual and tactile motion. We find that while summation produced a generic, non-specific improvement of thresholds, probabl...

A large number of occupational exposure limit values (OELs) are based on avoiding of sensory irritation of the eyes and the upper respiratory tract. In order to investigate the chemosensory effect range of a chemical, odor and sensory irritation thresholds (lateralization thresholds, LTs) can be assessed. Humidity affects olfactory function and thus influences odor thresholds; however, a simila...
