How does spasticity affect movement in stroke patients?

Spasticity is characterized by an abnormal increase in muscle tone and reflexes, which often occurs after a stroke due to damage to the parts of the brain that control movement. This condition results in stiffness and tightness in the muscles, leading to resistance when attempting to move. In stroke patients, the increased muscle tone can significantly impact their ability to perform voluntary movements, as the muscles may remain excessively contracted. This heightened muscle tone can lead to difficulties with coordination, balance, and overall mobility, making rehabilitation and recovery more challenging. By understanding the effects of spasticity, practitioners can design more effective interventions to mitigate its impact and improve functional outcomes for stroke patients.
