A group of 49 patients with 74 injured digital nerves was studied more than 5 years following epineurial nerve suture. Three tests of return of sensibility were used: von Frey plastic filaments, a modified Weber two-point discrimination device, and a dynamic test--the plastic ridge. The correlation between two-point discrimination and tactilegnosis in the range of 8 to 12 mm was poor. The plastic ridge device detects the presence or absence of tactilegnosis in patients in the intermediate range of two-point discrimination between 8 and 12 mm. Of the factors studied, the patient's age at the time of nerve suture was found to be directly related to the return of sensibility by both two-point discrimination and ridge criteria.
一组49例患者共74条指神经在进行神经外膜缝合术后接受了超过5年的随访研究。采用了三种感觉恢复测试方法：von Frey塑料细丝、改良的Weber两点辨别觉装置以及一种动态测试——塑料嵴测试。两点辨别觉与触觉识别在8至12毫米范围内的相关性较差。塑料嵴测试装置可检测两点辨别觉在8至12毫米中间范围内患者的触觉识别是否存在。在所研究的因素中，发现神经缝合时患者的年龄与两点辨别觉和嵴测试标准下的感觉恢复直接相关。
