Research methods


Motor Impairment Blog’s most popular posts

Over the past 4.5 years, researchers from all over the world have written non-technical summaries on their research for the Motor Impairment Blog. Consequently, the Blog contains a rich archive of information on topics such as muscle strength and weakness, falls and balance, sensation, pain, motor control, and research methods. […]


Jars of jam and muscle weakness in the morning

It’s 6AM. Last night, you missed dinner and you’ve woken up early because your body is ready for a feed. You stumble from your bedroom into the kitchen. You open the fridge and search for your favourite jar of jam. It’s nowhere to be found. Your partner finished it (without […]


Interview: Prof Andrew Creswell talks about the intrinsic muscles of the foot

Little is known about the small intrinsic foot muscles and their function during walking and running. In this video, Prof Andrew Creswell of the University of Queensland talks about the results of his research in which he has utilized imaging ultrasound and intramuscular electromyography to study the role of intrinsic […]


Are you reliably excitable?

Studies on motor impairments sometimes involve electrophysiological measures to assess the effects of therapeutic interventions.  For example, to determine the effect of an exercise program on brain function/excitability, a researcher might measure muscle responses elicited by non-invasive, magnetic stimulation of the brain (transcranial magnetic stimulation). When researchers plan their studies […]


Interview: Associate Professor Glen Lichtwark talks about microendoscopy in human muscles

With microendoscopy, it is now possible to study the microstructure of muscles in living humans with an unprecedented level of detail. Associate Professor Glen Lichtwark from the University of Queensland explains how microendoscopy can be used to gain a deeper understanding of how muscles adapt in response to, for example, training […]


Interview: Dr Martin Héroux talks about reproducibility of transcranial magnetic stimulation

Transcranial magnetic stimulation (TMS) is a popular method among neuroscientists to study brain function, because it enables selective activation of certain areas of the brain with a magnetic coil. However, results from TMS studies published in the scientific literature can often not be reproduced. NeuRA’s Dr Martin Héroux talks about findings […]


Muscle: a novel way to study its structure

Diffusion tensor magnetic resonance imaging (DT-MRI) is a novel technique used to study muscle architecture, and is currently being used for NeuRA’s motor impairment research. In his review paper, Damon et al. [1] comprehensively describes the details of the technique. In this blog, we cover some key elements to this […]


Interview: Professor David Vaux talks about Statistics and Publishing in Big Journals

At the second annual Motor Impairment Program meeting held at Neuroscience Research Australia at the end of last year, we were lucky to have guest speaker, Professor David Vaux from the Walter & Eliza Hall Institute for Medical Research (Melbourne, Australia) come up to talk to us about some general problems […]


The use and abuse of brain stimulation 2

Brain zapping, or non-invasive brain stimulation, in all its forms, has hit the mainstream.  You can even watch a YouTube video about how to build your very own not-approved-for-human-use transcranial magnetic stimulation machine!  Light-heartedness aside, the therapeutic benefits of brain stimulation are regularly highlighted in the news, and the number […]
