Quantitative grade and significance of sphincter ani externus myodynamia
Abstract：Objective To study the quantitative grade of sphincter ani externus myodynamia and to discuss the significance of using in convalescent of incomplete spinal cord injuries.Method A small water sac linked to KLP－ V30 intelligent measure of physiologic pressure was insered in to anal canal.Sphincter ani externus independence systolic pressure of 20 cases was measured from before lumbvar anesthesia to recovery.Meanwhile,both lower extremities sensorimotor score was dicumented.10 cases spinal cord injuries reconvalescent had been follow up .Result With the alteru of nerve functional status aftere lumbar anesthesia,sensorimotor score gradually rose,and sphincter ani externus myodynamia also rose by degrees.Accoding to the trial result,the myodynamia was divided 4 grades.Nomal myodynamia was about 25 mmHg.It was made clear that sphincter ani extermus myodynamia recovery of incomplete spinal cord injuries correlated with degree of spinal cord injuries and recoveries.Conclusion It might take as one reference of evaluation degree of spinal cord injury and its function recovery to make the quantitatvie grade of sphincter ani extermus myodynamia.
