Research and Analysis of Distribution Features of Nerves of Upper Extremity in Diabetic Peripheral Neuropathy

Objective To investigate conditions and distribution of upper extremity nerves involved in diabetic peripheral neuropathy(DPN) patients.Methods A total of 62 patients with DPN admitted to Boye County Hospital were included in DPN group,and 62 diabetes patients without peripheral neuropathy were included into the control group EMG/evoked potentials were used to detect sensation conduction velocity(SCV),sensory nerve conduction amplitude(SNAP),motor conduction velocity(MCV),compound muscle action potential amplitude(CAMP) of median nerve,ulnar nerve,radial nerve of all patients.Then indicators of different groups,different nerve conductions were compared.Results SCV of median nerve,ulnar nerve,radial nerve of DPN group were significantly lower than the control group[(40.5 ± 3.9) m/s vs(54.3 ± 4.3) m/s],[(44.2 ± 4.8) m/s vs(51.2 ± 5.8) m/s],[(46.1 ± 4.0) m/s vs(53.3 ± 6.1) m/s](P 0.05);MCV of median nerve,ulnar nerve,radial nerve of DPN group were significantly lower than the control group[(45.6 ± 5.5) m/s vs(54.3 ± 4.2) m/s],[(48.5 ± 3.9) m/s vs(55.0 ± 5.1) m/s],[(48.9 ±4.6) m/s vs(53.1 ±4.8) m/s](P 0.05).Abnormal rates of median nerve sensory nerve,motor nerve were significantly higher than the ulnar nerve,radial nerve(P 0.05),while there was no significant difference in abnormal rate between ulnar nerve and radial nerve(P 0.05);sensory nerve abnormal rates of median nerve were significantly higher than motor nerves(P 0.05).Conclusion Nerve conduction velocity of patients with DPN is significantly reduced,and the involvement of median nerve is most serious among upper extremity nerves,and sensory nerve is more serious than motor nerves.
