Clinical Neurophysiology

The Clinical Neurophysiology department at the RNOH is led by Dr Joseph Cowan, Consultant Neurolophysiologist. We provide a range of diagnostic services as well as supporting our surgeons with multimodal intraoperative neurophysiological monitoring during a variety of surgical procedures.  

The Neurophysiology team offers a range of services in both inpatient and outpatient settings.  

Consultant led Nerve conduction studies (NCS) and Electromyography (EMG) Clinic.

NCS and EMG are carried out by a doctor to assess nerve and muscle function.

These studies are helpful in the diagnosis of:

• Nerve injuries

• Nerve entrapments such as Carpal Tunnel Syndrome

• Peripheral neuropathy

• Other diseases of the nerves and muscles

Technician led Carpal Tunnel Syndrome (CTS) Clinic

Our highly skilled technicians perform nerve conduction studies in order to assess the function of the nerves running across the wrists to aid the diagnosis of Carpal Tunnel Syndrome.

Mobile Critical Care Electroencephalography (EEG) Service

Our new mobile EEG service is available to assist in the diagnosis or prognosis of patients in the critical care environment.  Please contact the department to discuss how this service may benefit your patients.

We do not provide a routine EEG service at this time.   

Intra-Operative Neurophysiological Monitoring (IONM)

The aim of IONM is to act as an early warning system to detect spinal cord compromise or nerve injury during surgery, helping the surgical team prevent or minimise permanent neurological injury.

The neurophysiology department have been providing IONM at Stanmore since the early 1980’s. As a centre of excellence for orthopaedic surgery the RNOH performs the most spinal surgeries in the UK.  As such our neuromonitoring team has a wealth of experience from monitoring in excess of 1000 procedures a year and is constantly evolving techniques in order to provide the best standards of care for our patients.

We provide comprehensive multi-modal intraoperative monitoring during a variety of orthopaedic and neurosurgical procedures in order to relay the functional status of the central and peripheral nervous system.

We also support our Peripheral Nerve Injury team during surgical procedures in order to determine the location and extent of any nerve damage. This enables them to take the most appropriate action
