Compound muscle action potential scan and MScanFit motor unit number estimation during Wallerian degeneration after nerve transections. Muscle Nerve 2020; 62:239-246. [PMID: 32415858 DOI: 10.1002/mus.26923] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2020] [Revised: 05/10/2020] [Accepted: 05/11/2020] [Indexed: 11/07/2022]
Abstract
BACKGROUND Compound muscle action potential (CMAP) scan and MScanFit have been used to understand the consequences of denervation and reinnervation. This study aimed to monitor these parameters during Wallerian degeneration (WD) after acute nerve transections (ANT). METHODS Beginning after urgent surgery, CMAP scans were recorded at 1-2 day intervals in 12 patients with ANT of the ulnar or median nerves, by stimulating the distal stump (DS). Stimulus intensities (SI), steps, returners, and MScanFit were calculated. Studies were grouped according to the examination time after ANT. Results were compared with those of 27 controls. RESULTS CMAP amplitudes and MScanFit progressively declined, revealing a positive correlation with one another. SIs were higher in WD groups than controls. Steps appeared or disappeared in follow-up scans. The late WD group had higher returner% than the early WD and control groups. CONCLUSIONS MScanFit can monitor neuromuscular dysfunction during WD. SIs revealed excitability changes in DS.

Complete and Fast Recovery from Idiopathic Facial Paralysis Using Laser-Photobiomodulation. Case Rep Dent 2020; 2020:9867693. [PMID: 32231809 PMCID: PMC7091526 DOI: 10.1155/2020/9867693] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2019] [Revised: 02/25/2020] [Accepted: 03/03/2020] [Indexed: 11/23/2022] Open
Abstract
Idiopathic facial paralysis, also known as Bell's palsy, exerts a negative effect on the quality of life. Although the prognosis is good in the majority of cases, a significant percentage of affected individuals may have sequelae that can negatively affect their lives. The use of therapeutic measures as early as possible can improve the prognosis. This article describes the successful use of laser-photobiomodulation as a single therapy in a patient with Bell's palsy and confirms the possibility of using this therapeutic modality as a good choice, since it is a therapy that is painless, comfortable, and without systemic side effects. The findings demonstrate that the adequate use of laser-photobiomodulation can be an effective therapeutic option for patients with Bell's palsy, regardless of the age, shortening the recovery time obtained with conventional therapies and avoiding sequelae. Further studies are needed for the establishment of adequate protocols.
