Moisture Status of the Skin of the Feet Assessed by the Visual Test Neuropad Correlates With Foot Ulceration in Diabetes

Abstract

OBJECTIVETo examine the association between the moisture status of the skin of the feet with foot ulceration in subjects with diabetes.RESEARCH DESIGN AND METHODSA total of 379 subjects with diabetes were examined. Assessment of peripheral neuropathy was based on neuropathy symptom score, neuropathy disability score, vibration perception threshold, and the 10-g monofilament perception. The moisture status of the skin of the feet was assessed using the visual test Neuropad.RESULTSPatients with foot ulceration had more severe peripheral neuropathy and more often an abnormal Neuropad response. Multivariate logistic regression analysis demonstrated that the odds of foot ulceration increased with measures of neuropathy but increased also with an abnormal Neuropad response.CONCLUSIONSAn abnormal Neuropad response correlates with foot ulceration in subjects with diabetes. This finding, if confirmed prospectively, suggests that the Neuropad test may be included in the screening tests for the prediction of foot ulceration.

A Novel Shear Reduction Insole Effect on the Thermal Response to Walking Stress, Balance, and Gait

“…15 Strengths of our study include good measurement properties for the instrumentation used. [8][9][10][11][12]17,19,21,22 We also allowed for a thermal wash-out period 15 between testing and randomized the insole testing sequence. We assessed for gait and balance changes under single and dual task conditions.…”

Effect of Intensive Nursing Education on the Prevention of Diabetic Foot Ulceration Among Patients with High-Risk Diabetic Foot: A Follow-Up Analysis

“…Visual inspection of the skin for signs of dryness often caused by autonomic neuropathy is vital in avoiding cracks in the skin integrity. 25 Observing for signs of marking from socks or footwear or redness from pressure from improper footwear can highlight problems before they start to cause trouble. Checking of the color of the skin will give early warning of impending problems.…”

Influence of peripheral arterial occlusive disease on the Neuropad® test performance in patients with diabetes

“…Finally, it has been independently associated with foot ulceration in a cross-sectional study [22] and, if confirmed by prospective data, could perhaps be used to predict diabetic foot disease.…”
