Screening for Diabetic Peripheral Neuropathy: Subjective Versus Objective Measures

This study compared subjective screening modalities recommended in diabetic foot screening guidelines for the detection of diabetic peripheral neuropathy (DPN) with an objective measure, the NC-Stat DPNCheck ® . We assessed 63 participants (mean age 54.5 years ± 10.5) utilising subjective screening tools (Semmes-Weinstein 10-g monofilament, 128-Hz traditional tuning fork, neurothesiometer, O’Brien 128-Hz electronic tuning fork) and compared results with the objective automated sural nerve conduction test NC-Stat DPNCheck ® . A significant difference was found in the number of limbs classified with DPN between all screening tools ( P < .05). Therefore, this suggests that some screening modalities are more sensitive in diagnosing DPN than others, highlighting the importance of using multiple screening tools to a comprehensive understanding of the patient's neurological status. The findings also emphasize the need to incorporate objective measures in diabetic foot screening and encourage future research to establish a gold standard tool for DPN diagnosis.
