Modified Ashworth Scale

Purpose of the measure

The Modified Ashworth Scale is considered the primary clinical measure of muscle
spasticity in patients with neurological conditions. However, some publications question
its ability to measure spasticity and advocate the Modified Ashworth Scale as a rating scale to measure
abnormality in tone or the resistance to passive movements, since there is no clinically
direct method for measuring spasticity (Gregson, Leathley, Moore, Sharma, Smith &
Watkins, 1999; Pandyan, Johnson, Price, Curless, Barnes & Rodgers, 1999).
