Description of intervention(s) / exposure
Behaviour - Treadmill

Experimental: Treadmill condition - The intervention condition consisted of a single session of moderate-high intensity aerobic exercise (65% of heart rate reserve) for 30 minutes walking on a standard treadmill. The single treadmill session included a progressive increase in intensity to reach the target heart rate (approx. 5 mins) as well as a cooling down period (approx. 5 mins). The warm-up and cool-down were included as part of the total 30 minutes of walking exercise. Target heart rates were calculated using the Karvonen method [25] with levels adjusted for those taking heart rate lowering medications (i.e. beta blockers), following methods previously published in post stroke populations [26, 27]. Participants were asked to self-rate their intensity of exercise every 10 minutes verbally using BORG's 6-20 scale rating of perceived exertion [28]. Participants were instructed to walk at a pace that resulted in a rating between 11 (fairly light) and 14 (somewhat hard) on the scale.

Other: Control condition - The control condition involved an equivalent time period (30 minutes) of seated resting where participants were provided with an education session about the impact and effects of stroke by the same research assistant.

Summary
Brief summary
A single-blinded crossover study. Participants attended two separate sessions at the
university campus, completing an aerobic exercise intervention in one session and a resting
control condition in the other session. Sensorimotor adaptation was assessed before and after
each session. Participants were twenty people with chronic stroke. Intervention completed was
treadmill exercise at mod-high intensity for 30 minutes.
