Mandeville R, Brown J, Sheean G
Clin Neurophysiol . 2019 Mar; 130(5):701-706. PMID: 30875537
Objectives: Evaluate correlation between donor nerve semi-quantitative electromyography (sqEMG) and strength outcome in nerve transfer surgery. Methods: Retrospective review of pre-operative donor nerve semi-quantitative neurophysiology and post-operative recipient muscle force...

Mandeville R, Brown J, Sheean G
Neurosurg Focus . 2017 Jul; 43(1):E6. PMID: 28669296
A successful nerve transfer surgery can provide a wealth of benefits to a patient with cervical spinal cord injury. The process of surgical decision making ideally uses all pertinent information...

Allison D, Gertsch J, Mahan M, Sheean G, Brown J
Neurodiagn J . 2014 May; 54(1):28-35. PMID: 24783748
Unlabelled: The use of transcranial motor evoked potentials (TCMEPs) to detect and hopefully prevent injury to the brain, spinal cord, and peripheral nerves intraoperatively has increased greatly in recent years....

Brown J, Vivio N, Sheean G
Clin Neurol Neurosurg . 2012 Mar; 114(5):506-14. PMID: 22421247
Surgical interventions to improve function following nervous system injury have been in development since the early 1900s. Only recently these have been assimilated into a coherent approach which can be...

Sheean G
Med Hypotheses . 2012 Jan; 78(4):430-1. PMID: 22285626
Quantitative MUAP analysis is often based on outlier detection, in the case of neurogenic conditions, the finding of MUAPs that are larger than the limit determined from a reference normal...

Sheean G
Clin Neurophysiol . 2011 Sep; 123(3):621-5. PMID: 21903464
Objective: Motor unit action potentials (MUAPs) recorded by needle electrode reflect the functional state of the motor unit and its force-generating capacity, and are usually described morphologically (e.g. amplitude, duration)....

Sheean G
Med Eng Phys . 2011 Aug; 34(2):249-55. PMID: 21831690
Quantification in clinical, diagnostic electromyography (EMG) currently includes motor unit action potential (MUAP) analysis and interference pattern analysis. Early efforts to examine the frequency/power spectra of the interference pattern showed...

Truong D, Duane D, Jankovic J, Singer C, Seeberger L, Comella C, et al.
Mov Disord . 2005 Mar; 20(7):783-91. PMID: 15736159
Botulinum toxin type A (Dysport) has been shown in European studies to be a safe and effective treatment for cervical dystonia. This multicenter, double-blind, randomized, controlled trial assessed the safety...
