What is a key characteristic of the Modified Ashworth Scale?

The Modified Ashworth Scale is specifically designed to evaluate muscle spasticity, which is defined as an abnormal increase in muscle tone or stiffness that can interfere with movement and functional activities. This scale is often used in clinical settings to assess patients with conditions such as stroke, multiple sclerosis, or traumatic brain injury, where muscle spasticity can be a significant issue.

The assessment involves applying a passive stretch to a muscle and rating the resistance encountered. By doing this, healthcare providers can obtain a standardized measure of spasticity, which can inform treatment decisions and track changes over time. Understanding muscle spasticity is crucial for occupational therapy and rehabilitation professionals as it impacts the ability to perform everyday tasks and engage in meaningful activities.
