Ashworth Scale
Also known as Spasticity Assessment Scale. The Ashworth Scale is a clinical assessment tool used to measure muscle spasticity. It helps healthcare professionals determine the resistance felt during passive muscle stretching.
The Ashworth Scale is commonly used in neurological rehabilitation. It provides a simple way to assess increased muscle tone in patients with neurological disorders.
Why is the Ashworth Scale Important?
The Ashworth Scale helps clinicians identify the severity of spasticity. Therefore, it is useful for treatment planning and monitoring patient progress.
In addition, the scale allows healthcare professionals to communicate findings using a standardized scoring system. As a result, treatment outcomes can be compared over time.
Ashworth Scale in Physiotherapy
Physiotherapists frequently use the Ashworth Scale when assessing patients with stroke, cerebral palsy, multiple sclerosis, spinal cord injury, and traumatic brain injury.
The assessment involves moving a limb passively through its range of motion and grading the resistance encountered.
These findings help guide rehabilitation programmes and spasticity management strategies.
Ashworth Scale Grades
The Ashworth Scale uses the following grades:
- 0 – No increase in muscle tone
- 1 – Slight increase in muscle tone
- 2 – More marked increase in muscle tone
- 3 – Considerable increase in muscle tone
- 4 – Affected part rigid in flexion or extension
Higher scores indicate greater spasticity.
Everyday Example
A physiotherapist assessing elbow flexor spasticity after a stroke may use the Ashworth Scale to determine the severity of muscle tone and monitor improvement during rehabilitation.

Clinical Pearl
The Modified Ashworth Scale (MAS) is more commonly used in clinical practice because it includes an additional grade (1+) and provides greater sensitivity when assessing mild spasticity.
Frequently Asked Questions
What is the Ashworth Scale?
The Ashworth Scale is a clinical tool used to assess muscle spasticity by measuring resistance during passive movement.
What does a higher Ashworth Scale score mean?
A higher Ashworth Scale score indicates greater muscle spasticity and increased resistance to passive movement.
