ABSTRACT
Objective To explore the reason why the SPR could make the changes of Sensory Function of Lower extremities,and the clinical significance of these changes.Methods From February,2012 to August,2014,24 patients with spastic cerebral palsy who were consistent with the indications of SPR,had normal intelligence development,and express competence,and could cooperate with the test.To test the changes of Sensory Function of lower extremities preoperatively,1 week after SPR,such as haptics,superficial algaesthesis,temperature sensation,cinaesthesia,topesthesia,pallesthesia,deep pain sense,tactile localization sense,two point discrimination and pattern sense.Results There were 6 patients who present with skin paresthesia of lower extremities among the 24 patients after the SPR.Of the 6 patients,4 became normal 2 weeks later,1 became normal 3 weeks later,and the longest 1 became normal 6 weeks later.No instances with permanent sensory deprivation and anaesthesia were found.The proportions of the excised root of spinal nerves during the SPR in the groups with skin anaesthesia of lower extremities and without skin anaesthesia of lower extremities were 0.268 ± 0.049 and 0.193 ± 0.074 (P ＜ 0.05 respectively).The former was significantly higher than the latter.The changes of haptics,cinaesthesia,topesthesia,deep pain sense,tactile localization sense,two point discrimination,pallesthesia preoperatively,1 week after SPR were not significantly different (P ＞ 0.05).There were significant differences in the superficial algaesthesis,pattern sense and temperature sensation preoperatively and postoperatively (P ＜ 0.05).Both of them decreased compared with those of 1 week after SPR.Conclusion The slight damage to sensory function of lower extremities resulted from SPR may not affect the protectant sensory function of the body.The skin anaesthesia of lower extremities is probably concerned with the proportion of the excised root of spinal nerves during the SPR,but not associated with the age.The impaired symptoms of the sensory function of lower extremities resulted from SPR can spontaneous recover in 2-6 weeks after SPR.SPR is safely with the clinic research on the sensory function of lower extremities.
