Modified Ashworth Scale

In this article, we will discuss the Modified Ashworth Scale. So, let’s get started.

Modified Ashworth Scale

Modified Ashworth Scale is used as a simple measure of Spasticity (muscle tone).

0 – No increase in muscle tone

1 – Slight increase in muscle tone, manifested by a catch or by minimal resistance at the end range of motion when the affected part moves in flexion or extension.

1+ – Slight increase in muscle tone, manifested by a catch, followed by minimal resistance throughout the remainder range of motion.

2 – More marked increase in muscle tone through most of the range of motion, but the affected part/parts easily moved.

3 – Considerable increase in muscle tone, passive movement becomes difficult

4 – Affected part/parts rigid in flexion or extension.
