چکیده
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 sensory threshold, pain threshold and pain tolerance using a standard procedure. Result: The sensory and pain threshold, and the pain tolerance in persons with visual impairment was found 3.66 + 4, 8.35+ 4.14 , 13.19+4.93 respectively as compared to 9.96 + 2.7, 13.13+ 2.62, 15.41+ 2.88, respectively in subjects with normal vision . On statistical analysis these results were found to be statistically significant (p<0.05). Conclusions: The sensory and pain threshold and the pain tolerance in persons with visual impairment were found to be lower in persons with visual impairment.

Quantitative sensory testing (QST) has been used to assess neurological function in various chronic pain patient populations. In the present study, we investigated the ability of QST to reliably characterize somatosensory dysfunction in subjects with spinal cord injury (SCI) and neuropathic pain by measuring mechanical, vibration, and thermal detection and pain thresholds. Test-retest reliabili...
