VibroSense Dynamics: New Method for Assessment of Diabetic Neuropathy and Risk for Diabetic Foot Ulcers Presented at EASD
New Swedish study shows vibration can be used to measure diabetic neuropathy

MUNICH--(BUSINESS WIRE)--A new Swedish study presented today at the European Association for the Study of Diabetes (EASD) Annual Meeting in Munich offers a potential breakthrough in the early detection of diabetic foot ulcers. Using a measurement method called Multi-Frequency Vibrometry, the study shows a strong correlation between decreased sensory perception in patients’ feet and risk of foot ulcers. It is estimated that 10% of people with diabetes will have a diabetic ulcer at some point in their lives. Furthermore, such ulcers precede more than 80% of amputations in people with diabetes. The cost to the NHS in the UK alone is estimated at £650 million.

Led by Dr. Eero Lindholm, Consultant physician at Skånes University, the study was selected by EASD for an oral presentation. Dr. Lindholm and his group have studied patients with Type I Diabetes patients with or without diabetic foot ulcers and compared them with healthy volunteers. Sensory perception was tested using a specially developed VibroSense Meter from Swedish medical device company Vibrosense. These CE-marked instruments have been widely used for the last 10 years in mining and other industries for detecting neuropathy in hands. As a novel finding the data demonstrate that there is a strong correlation between sensory loss at low frequent vibration and foot ulcers in diabetic patients. Low frequency vibration has not been tested in diabetic foot patients before and the results can indicate impairment of sensory cells, Merkel cells and Meissner's corpuscles as a consequence of diabetes.

“The results are very promising and could lead to improved early detection of diabetic foot ulcers. We have found a strong correlation between foot ulcers and impaired tactile sensation at low vibration frequencies. The study will continue for three years enabling us to include more patients and broaden the body of evidence,” says Eero Lindholm.

Assessment of the diagnostic accuracy of Vibrasense compared to a biothesiometer and nerve conduction study for screening diabetic peripheral neuropathy

J Foot Ankle Res. 2023 Sep 28;16(1):65

Aims: Peripheral neuropathy is a common microvascular complication in diabetes and a risk factor for the development of diabetic foot ulcers and amputations. Vibrasense (Ayati Devices) is a handheld, battery-operated, rapid screening device for diabetic peripheral neuropathy (DPN) that works by quantifying vibration perception threshold (VPT). In this study, we compared Vibrasense against a biothesiometer and nerve conduction study for screening DPN.

Methods: A total of 562 subjects with type 2 diabetes mellitus underwent neuropathy assessments including clinical examination, 10-g monofilament test, VPT evaluation with Vibrasense and a standard biothesiometer. Those with an average VPT ≥ 15 V with Vibrasense were noted to have DPN. A subset of these patients (N = 61) underwent nerve conduction study (NCS). Diagnostic accuracy of Vibrasense was compared against a standard biothesiometer and abnormal NCS.

Results: Average VPTs measured with Vibrasense had a strong positive correlation with standard biothesiometer values (Spearman's correlation 0.891, P < 0.001). Vibrasense showed sensitivity and specificity of 87.89% and 86.81% compared to biothesiometer, and 82.14% and 78.79% compared to NCS, respectively.

Conclusions: Vibrasense demonstrated good diagnostic accuracy for detecting peripheral neuropathy in type 2 diabetes and can be an effective screening device in routine clinical settings.
