Poststroke Spasticity: Pathophysiology and Management An Accurate Evaluation of Spasticity

Stroke is a major contributor to long-term impairment and disability, affecting up to one-third of survivors and almost half of patients showing neurological deficit at six months. Spasticity affects approximately 25% of individuals within two weeks of a stroke and increases to 44% in patients who have had a second stroke. Severe or incapacitating spasticity affects 15% of post-stroke individuals. Poststroke spasticity is also linked to additional signs and symptoms of the upper motor neuron syndrome, such as simultaneous contraction of agonist and antagonist muscles, weakness of the muscles, and a lack of coordination. Spasticity arises due to aberrant neuroplasticity that develops after a stroke and there is currently no specific intervention method designed to address and correct this abnormal plasticity that takes place during the acute phase. Just before implementing any measures to deal with spasticity, it is crucial to evaluate the influence on the quality of life and level of severity. Several grading scales are used to measure spasticity such as the MAS and modified Tardieu scale.There are various therapeutic approaches that may be categorized into three main classes: physical, pharmaceutical, and surgical. Each class has a distinct purpose and is used at the appropriate moment to reduce the level of spasticity and improve the patient's health. Physiotherapy serves as a base of improving the patient's condition and facilitating the development of brain networks. The objective of post stroke spasticity management must include not only the reduction of muscle hypertonia, but also the evaluation of how post stroke influences functionality and overall mental health. Improper treatment or non-compliance may result in increased pain, joint contraction, and further disability. The goal is to assist the patient in achieving the best possible quality of life.
