Journal ArticleDOI

Hiroshi Oba,A. Yagishita,H. Terada,A. J. Barkovich,K Kutomi,T. Yamauchi,S. Furui,Toshio Shimizu,M. Uchigata,Kiichiro Matsumura,Masahiro Sonoo,M. Sakai,K. Takada,Arimi Harasawa,Koji Takeshita,Kohtake H,H. Tanaka,Shigeru Suzuki +17 more
TL;DR: The area of the midbrain on mid-sagittal MRI can differentiate PSP from PD, MSA-P, and normal aging.
Journal ArticleDOI
Multi-MUP EMG analysis--a two year experience in daily clinical work.
TL;DR: A new quantitative motor unit potential (MUP) analysis method, called multi-MUP analysis, is described, which is a type of decomposition analysis of the EMG signal and can be used in daily routine EMG analysis.
Journal ArticleDOI
The ability of MUP parameters to discriminate between normal and neurogenic MUPs in concentric EMG: analysis of the MUP “thickness” and the proposal of “size index”
Masahiro Sonoo,Erik Stålberg +1 more
TL;DR: The new parameter, size index, is promising since it is more stable and gives better discrimination results than duration, since it was revealed that area/amp increases, that is, the MUP becomes thicker, as the amplitude decreases for each MUP with increasing recording distance.
Journal ArticleDOI
Dissociated small hand muscle atrophy in amyotrophic lateral sclerosis: frequency, extent, and specificity
Satoshi Kuwabara,Masahiro Sonoo,Tetsuo Komori,Toshio Shimizu,Fumiko Hirashima,Akira Inaba,Sonoko Misawa,Yuki Hatanaka +7 more
TL;DR: Prominent muscle atrophy in APB and FDI, with relatively preserved ADM appears to be specific to ALS, and presumably reflects part of the pathophysiology and supports the diagnosis of ALS.
Journal ArticleDOI
Assessment of variability in the shape of the motor unit action potential, the “jiggle,” at consecutive discharges
Erik Stålberg,Masahiro Sonoo +1 more
TL;DR: Simulations showed that increased jitter of the constituent single fiber potentials increases the jiggle as expressed by an increase in CAD and decrease in CCC values, which will increase the information obtainable from routine EMG investigations.
