The speed of strength: how often should you train one arm to increase strength in both arms?

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). […]

Aerobic exercise enhances fluid intelligence in stroke patients

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 […]

Plasticity of lower-limb motoneurons after spinal cord injury

Several neuromodulatory strategies have been used to improve leg function in individuals with spinal cord injury. These strategies include: electrical stimulation of the lumbar spinal cord (Harkema et al. 2011), operant conditioning of spinal reflexes (Thompson et al. 2013), and magnetic stimulation of a part of the brain that controls […]
