What type of movements does chorea involve?

1. Rhythmic, smooth movements

2. Sudden jerking movements

3. Coordinated athletic movements

4. Delayed reaction movements

The correct answer is: Sudden jerking movements

Chorea is characterized by sudden, irregular, and unintentional movements that can affect various parts of the body. These movements are often described as jerky and can occur spontaneously. They are typically unpredictable and can range from mild to severe, interfering significantly with normal activities. Individuals with chorea may experience these movements in the arms, legs, trunk, and even facial muscles. The nature of these movements distinguishes chorea from other types of motor disturbances, such as athetosis, which involves slow, writhing movements, or dystonia, which encompasses sustained muscle contractions. The suddenness of the movements in chorea aligns with the understanding of this condition as being driven by dysfunctional neural pathways that affect motor control. The other options present variations of movement types that do not align with the characteristics of chorea. For instance, rhythmic, smooth movements are typically associated with coordination and balance found in more stable motor functions, while coordinated athletic movements imply an element of intention and regulation that is absent in the involuntary actions seen with chorea. Delayed reaction movements suggest a lag in response time, contrasting with the abrupt onset associated with chorea.
