QST (Quantitative Sensorial Testing) Evaluation for the Diabetic Neuropathy Patients with Thin Fiber Damage

Abstract

Evaluation of QST (Quantitative Sensorial Testing) who diabetic patients have neuropatic pain with thin fiber damage. Thin fiber damage doesn't show with EMG at the patients who have diabetes mellitus depends on clinic neuropatic pain. In this patient group probable damage can show with QST also it can use efficacy of treatment observation. The patient group of 44 with diabetes have glove and socket like neuropatic pain, patients have normal EMG with the practice aim of QST their CS (cold sensation), WS (warm sensation), CPT (cold pain threshold), HPT (hot pain threshold) follow-up. In studied for 44 patients, 22 women-22 men admitted to diabetic. The average age of patients was 20-72 (48.97±13.07), their neuropatic pains were continuing for 3-18 months (10.40±5.27). 39 patients treated with oral antidiabetic and 5 of them treated with insulin. The average of blood glucose values were 125bmg/dl-198 mg/dl (154±18.86). The average VAS values on admission were 0-10 for CPT (6.5±1.73), HPT (5.65±1.92). QST evaluations were performed when we followed-up the evaluation of QST it determined 9.1% CS at 4 patients, 15.9% WS at 7 patients, 56.8% CS+WS at 25 patients of 44 patients. At 36 of patients 81.8% determinated sensation damage. QST evaluations of 37 patients were performed, HPT 4.6% at 2 patients, CPT 63.6% at 28 patients, HPT+CPT 15.9% at 7 patients 15.9% HPT+CPT identified pain threshold. As a result it's understood that follow-up and definition of neuropatic pain QST is an objective evaluation method as EMG.
