###Human: Why is there inability to walk or move after a stroke? ###Assistant: Hi. Ischemic stroke is a condition where there is incomplete blood supply to a certain part of the brain leading to permanent damage to that part of the brain. Consequently, the function carried out by the affected part of the brain is lost. The only way to recover function following permanent damage is physiotherapy which enables the existing normal part of the brain tore-learn the function that was earlier carried out by the now non-functional brain. In the case of your mother, physiotherapy is the only way to improve the lost function. In addition, we can make things in the house and around in a way that is easy for your mother to navigate such as having a motorized wheelchair, etc.
