Comparison of excitability findings between healthy control subjects and patients with diabetes (TNS grades 0, 1, and 2/3). A: Latency (ms) was significantly increased in grade 2/3 patients. B: RRP (ms) was prolonged in grade 2/3 patients. Recovery cycle parameters (C) superexcitability (%) and (D) subexcitability (%) demonstrated significant changes in all TNS grades. E: TEh (overshoot) was reduced in all TNS grades. F: TEd (10–20 ms) was reduced in patients with TNS grades 1 and 2/3. *P < 0.05; **P < 0.005; ***P < 0.0005.
