john pic Position     
Senior Lecturer (Neurophysiology)

Qualifications
BSc(Hons) PhD DipEd (NE)

Dr Burne lectures in the faculty's undergraduate and postgraduate neuroscience programs.  His lectures cover introductory and applied neurophysiology but focus on the control of movement and posture with an emphasis on movement disorders including stroke, spinal cord injury and Parkinson's disease.

Research field

Reflexes and limb biomechanics in health and disease

Muscle reflexes make important adjustments to the biomechanics of the limb in different tasks.  This adaptive role is frequently impaired in movement disorders and contributes to observed abnormal postures and movements such as those seen in stroke and Parkinson's disease. Parallel measures of limb biomechanics (joint stiffness, force and velocity relationships) and reflex activity (extracted from surface EMG) are providing a new perspective on these problems.

data collection

Serajul & Aparna are collecting reflex EMG data in response to mixed nerve stimulation.

1. The contribution of stretch reflexes to joint stiffness in posture and voluntary  movement 

A servo-controlled DC torque motor is being used to deliver stretch perturbations to muscles of the upper and lower limbs at rest and during voluntary contractions. The tonic stretch reflex and mechanical responses to the perturbation are extracted at different phases of postural and movement tasks.

2. Normal and pathological forms of muscle tremor

Muscle tremor is a factor limiting performance in tasks of the upper limb. Tremor in the context of neurological disease may increase in amplitude to the extent that severe disability results. This research has focussed on mechanisms underlying normal and pathological tremor and the application of quantitative measurement to clinical evaluation and therapy.

3. Reflexes originating from tendon afferents

Electrical stimulation of muscle tendons results in strong inhibitory reflexes but the role of such reflexes is sill unclear yet the same reflexes are depressed in patients with severe muscle tremor.
