In MAS scoring, which description corresponds to a score of 1+?

• A. No increase in tone.
• B. Slight increase in tone with a visible catch.
• C. Catch followed by minimal resistance.
• D. Rigid tone with no movement.

Answer: (C)

The key idea here is how the Modified Ashworth Scale describes subtle differences in spasticity during passive movement. A “catch” is that sudden, brief spike in resistance you feel at the start of stretching a muscle. For a score of 1+, the description is a catch that is then followed by a small amount of resistance that persists through the remainder of the movement. That’s why the description “catch followed by minimal resistance” best fits the 1+ level. Other descriptions describe either no change (0), a catch with release or resistance only at the end of the range (1), or a much greater, more sustained resistance that makes movement difficult (higher scores).
