Electromyography (EMG) and nerve conduction
This clinic evaluates children and young adults suspected of having a nerve or muscle disorder. This can include acquired causes such as a traumatic injury or a possible hereditary cause. Our clinic performs several diagnostic tests depending on the individual’s clinical symptoms. These tests include: nerve conduction studies, repetitive nerve stimulation studies, EMG, single-fibre EMG and stimulated single fibre EMG.
The neurophysiology laboratory performs routine EEGs as well as prolonged outpatient EEGs. We are also developing an Epilepsy Monitoring Unit (EMU) which will consist of inpatient beds dedicated to the monitoring of patients with epilepsy and suspected epilepsy, using simultaneous recording of video and EEG over extended periods of time. The unit will include a multi-disciplinary team of epileptologist, EEG technologist, nurses, neuropsychologist and medical social worker.
Evoked potentials (EPs)
Evoked potentials include pattern reversal visual evoked potentials (VEPs), short latency somatosensory evoked potentials (SSEPs) and brainstem auditory evoked potentials (BAEPs).
Theclinical value of evoked potentials (EPs) is based on their ability to:
- Demonstrate abnormal sensory system conduction, when the history and/or neurological examination is equivocal
- Reveal subclinical involvement of a sensory system (‘‘silent’’ lesions)
- Identify demyelination which is suggested by symptoms and/or signs in another area of the central nervous system
- Help define the anatomic distribution and give some insight into pathophysiology of a disease process
- Monitor changes in a patient’s neurological status
