- The Ashworth Scale measures the effects of antispasticity drugs in individuals with multiple sclerosis (it has subsequently been adapted for other diagnoses, including SCI).
- The Modified Ashworth Scale measures resistance during passive soft-tissue stretching and is used as a simple measure of spasticity in patients with lesions of the Central Nervous System.
- This measure is commonly used in the clinical setting to assess spasticity in people with SCI. However, it should be noted that spasticity is a multi-faceted construct with individual components of spasticity weakly related to each other suggesting that different clinical scales measure unique aspects of spasticity.
- This measure assesses single-joint resistance to passive ROM or a velocity dependent stretch reflex. They do not address spasm frequency or severity, nor do they differentiate between phasic and tonic components of spasticity. Therefore, the overall construct of spasticity is best measured with an appropriate battery of tests including the Ashworth or Modified Ashworth.
- The Ashworth and Modified Ashworth are well-tolerated by patients.
- This measure is easily administered during routine clinic visits and doesn’t require specialized equipment.
