Which of the following is a red flag during exercise for Parkinson's disease?

• A. Normal gait.
• B. Frequent falls.
• C. Consistent blood pressure.
• D. Rapid improvement in balance.

Answer: (B)

Frequent falls during exercise show impaired balance and postural control, which are common and potentially worsened in Parkinson’s. This safety red flag means the activity needs to be slowed, simplified, or supervised, and may prompt adjustments to the routine, footwear, environment, or medication timing to prevent injury.

Normal gait, stable blood pressure during exertion, and rapid improvement in balance are not signals of danger in this context. Normal gait suggests functioning balance, stable blood pressure indicates good cardiovascular response, and unusually fast balance gains would be unexpected and not a safety concern.
