Most stroke survivors regain the ability to walk; however, the gait pattern may be deficient (Yelnik 1999). Walking after stroke has been identified as the top priority for rehabilitation (Chan 1997). People who have had a stroke have a low level of ambulatory activity (Michael 2005). Hemiparesis is one of the most common post-stroke impairments that contributes to reduced gait performance. It has been noted in the literature that people with hemiparesis walk significantly slower than healthy persons and after six months reach only 40% to 50% of the walking distance of age-matched healthy people (Pohl 2002). The pattern of walking deviates due to many internal factors, such as inadequate or abnormal muscle recruitment or muscle weakness leading to an inability to initiate or control joint movements. Paralysis hinders foot positioning and loading when standing (Lee 2005). The hemiparetic foot frequently adopts a plantar-flexed position, not only in the swing phase but often throughout the stance phase as well. This may be due to the presence of increased plantar flexor tone, inappropriate plantar flexor activity, plantar flexor contracture or dorsiflexor weakness. Regardless of its cause the plantar flexion results in lack of weight bearing on the heel. As a further consequence the excessive plantar flexion resists forward rolling of the tibia over the ankle joint leading to knee hyperextension, therefore the ground reaction force (GRF) passes in front of the knee leading to instability. In addition, the plantar-flexed position pulls the GRF in front of the hip causing an excessive flexion moment of the hip during the late stages of the stance phase (Meadows 2008). It is clearly stated in the literature that hemiparesis induces ankle control disturbances and equinovarus deformity, leading to difficulty in walking and an increased risk of falling (Abe 2009).
