Abstract

This study evaluated the ability of the slipping slipper sign (defined as unknowingly losing a slipper while walking) to identify diabetic neuropathy in Jamaican patients. A single question was used to ascertain the presence of the slipping slipper sign (SSS) among 69 patients attending a diabetes clinic. Nurses assessed pain, vibration and pressure perception among the same patients in order to detect diabetic neuropathy. The sensitivity, specificity and positive predictive value for the SSS were calculated. Eight participants (men=5, women=3) reported positive SSS. The SSS had a sensitivity of 28.6%, specificity of 100% and positive predictive value (PPV) 100% for neuropathy on at least one of the three tests. These findings indicate that the SSS has high specificity and PPV for diabetic neuropathy but the sensitivity is low. The sign may be a useful adjuvant to conventional methods of screening for severe neuropathy

PUBLICATION METRICS

PlumX Metrics provide insights into the ways people interact with individual pieces of research output (articles, conference proceedings, book chapters, and many more) in the online environment. Examples include, when research is mentioned in the news or is tweeted about. Collectively known as PlumX Metrics, these metrics are divided into five categories to help make sense of the huge amounts of data involved and to enable analysis by comparing like with like.
