Aim: Repair of peripheral nerves is recommended following transection. Systematic evaluation of longitudinal recovery in injury models is needed to improve patient management. Gompertz function provided straightforward interpretation and prediction of recovery outcomes. Materials & methods: Behavioural sciatic function index, measured 3days postinjury, and weekly for 12weeks following full nerve transection and repair (n=6) as well as crush injuries (n=6). Results: Gompertz parametrization provided early classification between types of traumatic peripheral nerve injuries following surgical repair. Results distinguished injury nerves (A: p<0.01;Ti: p<0.05; Ic: p<0.05 and outcome: p<0.01). Early prognostication of outcomes (crush: 5.5±0.3 and cut/repair: 8±1weeks) preceded current methods. Conclusion: Our findings identify injury type, state of recovery and early prognostication of outcome.
