ABSTRACT
Objective To observe and analyze the clinical values of ultrasonic and electromyography exami-nation in lumbosacral nerve root lesions and peripheral neuropathy of lower extremity.Methods The prospective clinical study was performed.A total of 32 cases of suspected lumbosacral nerve root disease were recruited.All patients underwent ultrasound and electromyography examination to eliminate peripheral neuropathy;a total of 15 cases of suspected peripheral neuropathy patients were recruited to eliminate lumbosacral nerve root lesions.Results Among 32 cases of lumbosacral nerve root lesions,neuromuscular electrical diagram screening found 4 cases of periph-eral neuropathy(12.5%),and ultrasound screening found 5 cases of peripheral neuropathy(15.6%).There was no significant difference between the two groups(P >0.05).Among 15 cases of peripheral neuropathy,neuromuscular electrical diagram screening found 3 cases of lumbosacral nerve root lesions(20.0%),and ultrasound screening found 0 case of lumbosacral nerve root lesions.There was no significant difference between the two groups(χ2 =6.47,P <0.05).Conclusion Neuromuscular electrical diagram inspection and ultrasonic inspection in the lumbosacral nerve root lesions in the differential diagnosis of lower limb peripheral neuropathy has certain clinical values.Detection rate regarding lower limb peripheral neuropathy has no significant difference between the two methods.
