Sleep disruption and sleep-disordered breathing (repetitively stopping breathing or insufficient breathing during sleep), may be important factors in the management of multiple sclerosis (MS). MS is a chronic autoimmune disease of the central nervous system. Types of sleep-disordered breathing include obstructive sleep apnea and central sleep apnea. Obstructive sleep apnea […]
When you take a breath, many muscles in your body contract in a coordinated pattern to let air flow in and out of your lungs. While most of the muscular work for breathing is done by the diaphragm muscle in the abdomen, the muscles in the upper airway also play […]
Inspiratory muscle motoneurone pools are linked via many reflex connections. These reflexes are largely inhibitory and can operate over several segments. Much of our knowledge of these reflex connections comes from studies in animals (Marlot et al. 1988, Speck & Revelette. 1987). In humans, we know that stimulation of the phrenic nerve […]
Nerve cells that innervate the biceps muscle become more (or less) excitable depending on the posture of the arm (Mogk et al. 2014). This has been shown by stimulating the motor area of people’s brains (the motor cortex) and measuring the size of responses in the muscles when the arm […]
Scientists publish their most important findings in scientific journals. But who reads those journals? Almost exclusively other scientists. That means that the vast majority of people, who fund the research through their taxes, will never hear about the results even though they might be important for them. Professor Lorimer Moseley […]
In a recent interview, Simon Gandevia talks about a recently published review article by Stephen Lord, Kim Delbaere and himself which examined how motor impairments become more prevalent with ageing and how careful physiological measurement and appropriate interventions offer a way to maximise health across the life span. PUBLICATION: Lord SR, […]
Members of the Motor Impairment Research Program conducted a randomized controlled trial to assess whether step training can improve physical and neuropsychological measures associated with falls in people with multiple sclerosis (MS). 50 people with MS participated in the trial in which intervention group participants (n = 28) performed step […]
Ahead of the second annual Motor Impairment meeting, Simon Gandevia, Deputy Director of Neuroscience Research Australia, talks about Motor Impairment; what it is and what he and his colleagues at NeuRA are investigating as part of the NHMRC-funded program grant.
Strength training consists of repetitive high-force muscle contractions. Strength training for four weeks improves maximal strength (Carroll et al. 2011). These strength gains are primarily the consequence of changes in the nervous system and are not simply due to an increase in muscle size (e.g., Weier et al. 2012). In […]
Most of the time, our breathing is controlled involuntarily so that we don’t need to consciously think about breathing in and out all the time (for reviews, see Feldman & Del Negro, 2006; Richter & Smith, 2014). However, there are many instances where we need to voluntarily control how fast […]
