Neuroimaging the brain areas activated by muscle and cutaneous afferents

Inputs from specialised cutaneous and muscle afferents are crucial for tactile manipulation and accurate movement and postural control.  Both sets of afferents project to the cerebral cortex and contribute to proprioceptive senses (e.g. Proske & Gandevia, 2012).  We used functional magnetic resonance imaging (fMRI) to compare the cortical activation produced by cutaneous […]


How do we know the location of something we feel on our skin?

When we are touched on the skin, sensory receptors in that location fire and send a signal via nerves to the brain, but this is not enough to let us know where on our body the touch occurred. To decipher where the touch is on the body, the brain needs […]

Participant seated in the experimental apperatus. Visible are the leather sleeve and metal occluder positioned on the participant's left forearm. The skin on either side of the metal occluder was brushed (not pictured), and the effect this had on touch localization was assessed by participants pointing on a digitizing table (gray divider between the subject's body and left arm) where they felt the tactile target.

The effects of fatigue on reaction time in people with multiple sclerosis

People with Multiple Sclerosis (MS) often report fatigue and reduced capacity for walking as some of their most disabling symptoms (1-3). Indeed, fatigue is often reported after relatively short bouts of walking. However, the functional consequences of this fatigue are not well known. We were interested in how walking might […]


The human upper airway and its neuromechanical behaviour

Obstructive sleep apnoea is a common disorder which is linked to increased incidence of stroke, myocardial infarction and heart failure (for review see Jordan et al 2014).  However, the fundamental neuromotor control of the upper airway is poorly understood, perhaps because of its structural and neural complexity.  Recently a series […]


Balancing act: calf muscles and standing balance

Similar to a pencil balanced on a finger tip, the standing human body is inherently unstable (Loram & Lakie, 2002). The vertical projection of the body’s center of mass passes in front of the ankle when we stand, which means active plantar flexion of the ankle is required to maintain […]


Should we train proprioception in people with knee osteoarthritis?

Knee osteoarthritis (OA) is a painful condition that can substantially interfere with peoples’ daily activities. It will affect one in two people over their lifetime and is more likely in people who are overweight (Murphy et al., 2008). In light of the existing literature regarding joint function in people with […]


Accelerometers used to measure head jerk.

Older people really do have ‘jerkier’ movements

Up to one in three people over 65 fall each year (Masud & Morris, 2001) and many older people have impaired dynamic stability. However, a cause and effect relationship between gait speed, step variability, dynamic stability, and falls is complex. For example, older people may walk more slowly to compensate […]


How common are joint contractures among people with multiple sclerosis?

Joint contractures, usually defined as limited passive range of joint motion, are common in people with neurological conditions such as stroke, spinal cord injury or multiple sclerosis (MS).  To date, there are no studies of the incidence and prevalence of contracture in a population with MS.  A recent systematic review […]
