Stroke is the commonest and most severe neurological disorder, causing reduced functional level, decreased quality of life and even loss of life. Researches with inconsistent outcomes and several procedural restrictions have been directed to evaluate the effectiveness of supervised versus unsupervised therapeutic exercise training on lower limb muscle strength, balance, and functional performance among patients with ambulatory chronic stroke.
In industrialized countries, stroke is the most frequent cause of disability among adults. The death rate following stroke is set to decrease as a result of better care provision as soon as the problem occurs. It can therefore be expected that the number of people surviving with a disability following a stroke is liable to increase (Eng JJ. 2010). In addition, the incidence of stroke has increased dramatically among younger subjects, with over 20% of people affected being under the age of 65 (Patten C, Lexell J et. al 2004).
