Single limb resistance training improves strength not only in the trained limb, but also in similar muscles of the untrained limb. The increase in strength in the untrained limb, commonly known as ‘cross-education’, is due to a strengthening of connections within the brain and spinal cord (Farthing and Zehr, 2014). […]
Fluid intelligence, sometimes called abstract reasoning, is the ability to think logically and solve problems; a highly valued human capacity. Over 70% of patients admitted to hospital with stroke have cognitive impairment, but cognition is rarely a target of rehabilitation treatments. Moderate-vigorous intensity aerobic exercise is a potent brain stimulus […]
Exercise-induced hypoalgesia is a reduction in pain that occurs during or following a single bout of exercise (Naugle et al, 2012). When researchers test exercise-induced hypoalgesia, they briefly induce painful stimuli to research participants to see if pain sensitivity changes after exercise. Different types of painful stimuli have been used […]
The loss of strength after stroke is a common and important impairment. Some people who have had a severe stroke can lose as much as 50–70% strength in the affected arm and leg (Andrews & Bohannon 2003; Horstman et al. 2008). This loss of strength can result in profound disability […]
How do we learn things? Sometimes learning occurs over many trials but other times it occurs after single episodes. The traditional view of learning has invoked Hebbian plasticity (Hebb 1949). Here, the concept is that “neurones that wire together, fire together”. Enhanced firing of a post-synaptic cell is thought to […]
If someone has suffered a leg injury in the past, they are at an increased risk of having that particular injury again in the future (Murphy et al. 2003). Oftentimes, this second injury is worse than the first. Knowing this, physiotherapists often design rehabilitation programs that target that particular body […]
Training improves task performance due to improved motor control through practice. Intriguingly, training with one limb can improve task performance with the other, untrained limb. This phenomenon is known as interlimb transfer or cross education, and it is important for rehabilitation when the most affected limb cannot engage in training […]
Previous research supports the use of resistance training as a safe and effective exercise intervention for disabled stroke patients (Lee et al. 2010; Pak & Patten 2008). Although resistance training programs for stroke typically target improvements in maximal muscle strength, gains in muscle endurance (i.e. the ability to sustain submaximal […]
Much can be learned from case studies of individual patients. This has been shown more than once in the field of stroke research. The observations by the illustrious neuroanatomist Dr. Brodal of his own stroke are an example (Brodal 1973). A paper recently published in the Journal of Neurophysiology provides […]
