4. Spasticity: A Stiff Hurdle to Overcome
Spasticity, characterized by muscle stiffness and spasms, is a common symptom experienced by those with pseudobulbar palsy. This rigidity can affect any muscle group but is more commonly seen in the limbs. It can impede movement and cause discomfort or even pain.
The root cause of spasticity in pseudobulbar palsy lies in the damage to nerve pathways controlling muscle movement. The disrupted signals from the brain lead to an imbalance between signals of muscle contraction and relaxation. This results in increased muscle tone or stiffness, making movements stiff and jerky.
Spasticity can significantly impact a person’s daily life, making simple activities like walking, dressing, or even holding objects difficult. It can also lead to painful muscle spasms and pose challenges in maintaining proper posture. If left untreated, spasticity can result in muscle and joint deformities over time. (4)
