Hoehn and Yahr Stage II is described as which?

• A. Unilateral symptoms, minimal disability.
• B. Bilateral symptoms, no postural instability.
• C. Bilateral symptoms, postural instability, physically independent.
• D. Severe disability, requires some assistance but can stand/walk unassisted.

Answer: (B)

The main idea is how Parkinson’s disease motor symptoms progress in the Hoehn and Yahr scale. In Stage II, symptoms are present on both sides of the body (bilateral) but balance is still preserved—there is no postural instability. Because of this, the person remains physically independent and can carry out daily activities without help.

This makes the description “bilateral symptoms, no postural instability” the correct fit for Stage II. Earlier stages involve unilateral symptoms, and later stages introduce postural instability and increasing disability, which aren’t present in Stage II.
