Two-point discrimination for ANG and CNC after three, six, and twelve months. Static two-point discrimination showed the first significant recovery compared to baseline after twelve months for the ANG group (A; p < 0.01). In contrast, CNC presented the first significant recovery compared to the baseline after three months (B; p < 0.05). Dynamic two-point discrimination revealed slightly superior results compared to static two-point discrimination, with the first significant results for ANG (C; p < 0.05) and CNC (D; p < 0.01) after three months. ANG: autologous nerve graft; CNC: chitosan nerve conduit; * p < 0.05, ** p < 0.01.
