Limiar de sensibilidade cutânea dos pés em pacientes diabéticos através do pressure specified sensory device: uma avaliação da neuropatia

Abstract

Altered values were observed for the static and dynamic tests over the three nerve territories studied. Differences were statically significant (p < 0.05). This numeric quantification of the threshold of pressure supports the evaluation of the status of the fiber/receptor structures as well as the functional deficit subsequent to diabetic neuropathy.

Reprodutibilidade intra-avaliador do teste de discriminação de dois pontos na sola dos pés em idosos e jovens assintomáticos

“…Cutaneous sensitivity tests are used to detect reduced sensory perception and to diagnose neuropathies and abnormalities of sensory function 18,30,31 . The TPD test is commonly used to assess upper limbs and airways cutaneous perception in several populations [30][31][32][33] .…”

“…Nylon monofilaments and the diapason test pitch have been used most often in the sensitivity evaluation of the lower limbs 11,[34][35][36][37] . Few studies have used the two-point discriminator for lower limbs, specifically for the sole of the feet 18,21 .…”

“…Studies that used this test on the sole of the foot, despite reporting significant results, did not present reproducibility data 18,21 .…”

“…There is also the PSSD TM (Pressure-Specified Sensory Device), a specific device of pressure sensitivity capable of determining thresholds of cutaneous sensitivity with more accuracy. This method, although used in several studies in the lower limbs, especially in individuals with diabetic neuropathy [17][18][19] , demands the use of force transducers and registration on a computer.…”

“…The TPD is frequently performed together with the monofilaments test and the perception of vibration test 8,20 and is included in some assessment protocols for cutaneous sensitivity 18 . Among these three methodologies, the TPD is the only one that has not had its reproducibility tested for evaluating the sole of the feet, although it is an easy test for clinical use and have low cost.…”
