Figure 5: Mean withdrawal reflex latency (WRL) and extensor postural thrust (EPT) results for 20 weeks followup. Values in seconds (s) were obtained performing withdrawal reflex latency (WRL) test to evaluate the nociceptive function (a). Values of motor deficit were obtained performing extensor postural thrust (EPT) test (b). This test has been performed preoperatively (week 0) at week 1, week 2, and every 2 weeks after the surgical procedure until week 20, when the animals were sacrificed for morphological analysis. Data displayed as mean SEM.
