OBJECTIVE: To investigate and describe the peak plantar pressures and ground contact times of the foot during walking in diabetic patients and healthy adults. METHOD: 17 age-matched diabetic patients without any complications and 33 healthy adults participated in this study. The foot was divided into 10 different areas, and peak plantar pressures and ground contact times were measured during walking by EMED system . RESULTS: There were no significant differences in peak plantar pressures of both feet in both groups, but there were significant increases in peak plantar pressures of hindfoot and hindfoot contact times in the diabetic group. CONCLUSION: Despite having no definite diabetic neuropathy and vascular disease, diabetic patients have higher peak plantar pressures of hindfoot and prolonged hindfoot contact times because limb muscle dysfunction or impairment of proprioception may induce faster descent of the foot towards the ground or improper pattern of stance phases.

Foot complications are a well known factor which contribute to the morbidity of diabetes and increases the chance of amputation. A total of 126 consecutive diabetic patients were evaluated by diabetic foot screening. Forty-one patients showed an impaired protective sense when tested with Semmes-Weinstein monofilament 5.07 (10 g), and 92% of them showed peripheral polyneuropathy in nerve conduction study (NCS). The mean vibration score of the Rydel-Seiffer graduated tuning fork in patients with peripheral polyneuropathy in nerve conduction (NCV) study was 5.38+/-2.0, which was significantly different from that of patients without polyneuropathy in NCS. Among the deformities identified on examination, callus, corn, and hallux valgus were the greatest. While checking the ankle/ brachial index (ABI), we also evaluated the integrity of vasculature in the lower extremities. After extensive evaluation, we classified the patients into eight groups (category 0,1,2,3,4A,4B,5,6). The result of this study suggested that the Semmes-Weinstein monofilament test, Rydel-Seiffer graduated tuning fork test, and checking the ankle/brachial index were simple techniques for evaluating pathologic change in the diabetic foot by office screening, and that this screening based on treatment-oriented classification helps to reduce pedal complications in a diabetic population

Diabetic polyneuropathy (DPN) causes neuropathic pain with reduced quality of life as well as diabetic foot ulceration which sometimes resulted in amputation. Early detection and improved knowledge of pathogenic pathways are important to prevent and to manage DPN. The screening methods and several tests to diagnose DPN-quantitative sensory testing, skin biopsy, corneal confocal microscopy, etc.-will be described.

Diabetic peripheral neuropathy(DPN),a chronic diabetic microvascular complication with a high incidence among diabetic patients,increases the risk of diabetic foot and amputation.Many methods are available for screening and evaluating DPN,including traditional 10 g monofilament,tuning fork and vibration perception,and tendon reflex tests,which should be combined with some nerve function score systems to improve the detection rate and accuracy for DPN.In recent years,a number of noninvasive new techniques have been developed for the evaluation of nerve injury,such as corneal confocal microscopy,quantitative sensory testing,current perception threshold test,sympathetic sudomotor function evaluation,and quantitative detection of skin advanced glycation end products.This paper reviews these noninvasive methods for screening and evaluating DPN to help clinicians detect and focus on DPN early.

This article provides an overview for understanding the classification and pathogenesis of diabetic neuropathy. Diabetic neuropathies are prevalent disorder. The most common manifestation is distal symmetric polyneuropathy, but various patterns of neuropathy can occur. New information for the pathogenesis of diabetic neuropathy continues to emerge, which will lead to identifying new drug targets.
