Ashworth Scale for Spasticity
The Modified Ashworth Scale (MAS) is a clinical rating scale for assessing muscle spasticity, quantifying the resistance to passive movement on a 0-4 scale plus an additional grade. Originally developed by B. Ashworth in 1964 and refined by Bohannon and Smith in 1987, the MAS is the most widely used bedside tool for evaluating spasticity in stroke survivors, individuals with cerebral palsy, multiple sclerosis, and spinal cord injury.
