• brady-: Slow Example: Bradykinesia – Slowness of movement, often a symptom of neurological disorders like Parkinson’s disease, affecting motor function and coordination.

• dys-: Painful, difficult, abnormal, labored Example: Dystonia – A condition characterized by abnormal muscle tone or involuntary muscle contractions, which can lead to repetitive movements, abnormal postures, and impaired function.

• hyper-: Above, excessive Example: Hypertonia – Excessive muscle tone, resulting in stiffness or rigidity, commonly seen in conditions like cerebral palsy or stroke.
