In muscular dystrophy (MD), the mid-stage RPE is which range?

• A. 2-4/10
• B. 0-2/10
• C. 1-3/10
• D. 6-8/10

Answer: (C)

The question is about how hard a person with muscular dystrophy should work during mid-stage rehab, using the Rating of Perceived Exertion (RPE) scale from 0 to 10. In mid-stage MD, you want a light to light-to-moderate effort that the person can sustain without excessive fatigue. The range of 1-3/10 fits this well: it signals light exertion, still allowing conversation and control of fatigue, but not underworking activity.

Ranges at or near 4 or higher would push into moderate or greater effort, which is typically avoided in mid-stage rehab to protect fatigable muscles and prevent overexertion. Very low ranges like 0-2 can be more than what mid-stage requires, and high ranges like 6-8 are too demanding for this stage. So 1-3/10 is the best fit for mid-stage RPE.
