英文摘要:

Objective. - To study the relationship between current perception threshold (CPT) and somatosensory evoked potential (SEP) in diabetes.

Methods. - Both CPT and SEP were recorded in 66 diabetic patients. Both the CPT scores (measured at 2000 Hz, 250 Hz, and 5 Hz stimulations) and SEP (peak latency at ERB′s point [Lat (ERB)] and popliteal fossa [Lat (PF)]; interpeak latency of "ERB to 7th cervical vertebra" [Delta lat (ERB-C7)] and "popliteal fossa to lumbar vertebra" [Delta lat (PF-FO)]) were recorded in both upper and both lower limbs, separately. t-tests and correlation analyses were performed to assess relationships between CPT and SEP tests.

Results. - After adjustment for height and/or age, CPT scores at 2000 Hz were significantly correlated with Lat (ERB) (left: rho=0.408, P<0.05; right: rho=0.297, P<0.05), Delta lat (ERB-C7) (left: rho=0.238, P<0.05; right: rho=0.385, P<0.05), and Lat (PF) (rho=0.216, P<0.05), and those at 250 Hz were moderately correlated with Lat (ERB) (left: rho=0.234, P<0.05; right: rho=0.306, P<0.05). CPT scores at 5 Hz were not significantly correlated with any SEP measurements (P>0.05).

Conclusions. - Both CPT scores at 2000 Hz and SEP may reliably determine large-fiber function in diabetic neuropathy. (C) 2012 Elsevier Masson SAS. All rights reserved.
