VibraTip: A pocket-sized disposable device for testing the integrity of sensation in the outpatient setting.
ABSTRACT Aims To compare the Ipswich Touch Test and the VibraTip with the Neuropathy Disability Score and the vibration perception threshold for detecting the 'at-risk' foot. Methods We directly compared the Ipswich Touch Test and the VibraTip with both the Neuropathy Disability Score ≥ 6 and the vibration perception threshold ≥ 25 V indicating 'at-risk' feet in 83 individuals. Results The vibration perception threshold and Neuropathy Disability Score tests exhibited almost perfect agreement with each other (P < 0.001). The VibraTip and Ipswich Touch Test results were identical (P < 0.001). The VibraTip and Ipswich Touch Test results also exhibited almost perfect agreement with the vibration perception threshold (P < 0.001) and the Neuropathy Disability Score (P < 0.001). Conclusions These two simple and efficient tests are easy to teach, reliable and can be used in any setting, and neither requires an external power source. We conclude that both the VibraTip and the Ipswich Touch Test are reliable and sensitive tests for identifying the 'high-risk' foot. © 2012 The Authors. Diabetic Medicine © 2012 Diabetes UK.

ABSTRACT: At any one time 2% to 4% of the diabetic population is likely to have an active foot ulcer. Peripheral neuropathy, foot deformity, and trauma (often from ill-fitting footwear) represent the commonest causal pathway to foot ulceration. All patients with diabetes require an annual foot screen, and those found to be at risk require specialist foot care and preventive foot-care education. Identification of the high-risk foot can be achieved without the need for expensive equipment. Understanding the implications of loss of protective sensation is essential in reducing the all too high incidence of foot problems in diabetes.The Medical clinics of North America 09/2013; 97(5):775-90. · 2.18 Impact Factor

ABSTRACT: New modalities are now available to improve the diagnosis of diabetic polyneuropathy (DPN). The present review discusses the progress achieved in this area. First, the minimal diagnostic criteria have been better clarified. Moreover, there are now new bedside tests available, such as the indicator test Neuropad, NeuroQuick, Ipswich Touch Test (IpTT), Vibratip, NC-stat(®)/DPNCheck™ for automated nerve conduction study (NCS), tactile circumferential discriminator, steel ball-bearing, and SUDOSCAN(®), while more sophisticated modalities include skin biopsy and corneal confocal microscopy (CCM). Some tests can be used as screening tools, including primary care setting (Neuropad, IpTT, Vibratip, automated NCS), while others are more suitable for research, including evaluation of DPN in prospective studies (CCM, skin biopsy). Importantly, there is some evidence of earlier DPN diagnosis with the aid of some tests (Neuropad, skin biopsy, CCM). Further advantages provided by different tests are educational value and self-examination. Thus far, the potential of these tests has not been fully utilised. In particular, they have not been validated against standardised clinical examination scores in terms of predicting foot ulcers and amputations. Hence, it now remains to investigate the potential benefits from the widespread use of these tests for earlier and easier diagnosis of DPN in the everyday clinic.Endocrine 05/2014; · 1.42 Impact Factor
