Aim and Introduction: It is often assumed that persons with visual impairment have a better sensory perception this ability helps them to perceive the environment better. To objectively study this assumption we carried out a study on sensory, pain thresholds and pain tolerance in persons with visual impairment. Materials and Methods: An electrodiagnostic stimulator was used to assess the sensor...

[Purpose] This study investigated two-point discrimination (TPD) and the electrical sensory threshold of the blind to define the effect of using Braille on the tactile and electrical senses. [Subjects and Methods] Twenty-eight blind participants were divided equally into a text-reading and a Braille-reading group. We measured tactile sensory and electrical thresholds using the TPD method and a ...

Sensory strength-duration curves were obtained using percutaneous true square-wave pulses ranging from 0.1 to 20.0 ms produced by an isolated constant current stimulator. In 119 healthy volunteers sensory thresholds were measured bilaterally by stimulating the distal phalange of the little finger. In order to examine the relationship of sensory threshold and handedness the latter was assessed b...

Mechanisms underlying the binocular combination of visual information were investigated within the context of a visual information acquisition theory proposed by Loftus, Busey, and their colleagues (e.g., as described by T.A. Busey & G. R. Loftus, 1994). A central assumption of the theory is that of a sensory threshold, which engenders an information loss such that information processing subseq...

Subjective sensory abnormalities, such as radiating pain, dysesthesia and llodynia, are a common feature of patients presenting to a pain clinic. Objectively quantifying those abnormalities using subjective tests ( eg tuning fork, safety pin) may be difficult. There are a number of non-invasive neurodiagnostic technologies available to supplement the history and physical exam including MRI, the...

BACKGROUND The effect of acupuncture on sensory perception has never been systematically reviewed; although, studies on acupuncture mechanisms are frequently based on the idea that changes in sensory thresholds reflect its effect on the nervous system. METHODS Pubmed, EMBASE and Scopus were screened for studies investigating the effect of acupuncture on thermal or mechanical detection or pain...

Objectives. To investigate whether sensory function declines independently or in parallel with age within a single individual. Methods. Cross-sectional analysis of Baltimore Longitudinal Study of Aging (BLSA) participants who underwent vision (visual acuity threshold), proprioception (ankle joint proprioceptive threshold), vestibular function (cervical vestibular-evoked myogenic potential), hea...

Pressure threshold measurements were made using a set of three Semmes-Weinstein monofilaments on 1 32 plantar u\cer sites in 72 leprosy patients and 45 plantar u\cer sites in 28 diabetic patients. The most common sites of u\ceration were the great toe and first metatarsal head. No patient could feel monofilaments smaller than 6 · \ 0 (75 g) . The next smallest filament, 5 ·07 ( 1 0 g), was iden...
