重建外科的挑战之一是确保正中神经修复后恢复手的感觉。我们评估了54名患者(平均年龄32[4-72]岁)在腕部水平横断正中神经或尺神经修复后的触觉知觉。我们发现，神经修复后感觉再学习有一个明确的关键期。在5-10岁以下有一个最佳的能力，然后迅速下降，在青春期后趋于平稳。这一曲线与之前公布的移民语言习得关键期的数据相关联。神经修复后功能感觉的恢复是基于一个学习过程，在许多方面类似于学习第二语言。
One of the challenges In reconstructive surgery Is to ensure hand sensibility is regained after median nerve repair. We assessed tactile gnosis In 54 patients (mean age 32 [range 4-72] years) after repair of transected median or ulnar nerves at the wrist level. We found that there Is a well-defined critical period for sensory relearning after nerve repair. There Is an optimum capacity below age 5-10 years followed by a rapid decline, which levels out after puberty. The curve correlates with previously published data on critical periods for language acquisition among Immigrants. Recovery of functional sensibility after nerve repair Is based on a learning process and In many ways Is analogous to learning a second language.
