ABSTRACT
AIMS:
Abnormalities of external anal sphincter electromyography (EAS-EMG) characterize multiple system atrophy (MSA) and focal cauda equina or conus medullaris lesions. This study is designed to determine whether and how diabetic polyneuropathy (DPN) affects EAS as compared to the abnormalities seen in MSA.METHODS:
We conducted multi-motor unit potential (MUP) analysis of EAS in 22 healthy controls, 32 diabetes mellitus (DM) patients without neuropathy, 38 DPN patients, and 68 MSA patients.RESULTS:
DPN patients had a significant (P < 0.01) increase in MUP mean duration, mean amplitude, percentage of long duration MUPs, and satellite rate, but to a lesser extent than MSA. Mean duration and satellite rate showed the least overlap among different groups in individual value distributions.CONCLUSIONS:
Compared with MSA, DPN affects EAS to a lesser degree as judged by neurogenic MUP abnormalities in EMG. Mean duration and satellite rate may serve as the most discriminating aspects in MUP analysis of EAS.Palavras-chave
