Modified Ashworth Scale EXPLAINED [with Demonstrations]

The video tutorial explains the Modified Ashworth Scale (MAS), a tool used to assess muscle resistance to passive range of motion, primarily for spasticity evaluation. It is widely used for conditions like spinal cord injury, stroke, and cerebral palsy. The tutorial details how to assess spasticity in specific muscles, such as the biceps brachii and quadriceps, and explains the scoring system from 0 to 4, with examples for each score. The video emphasizes the importance of understanding muscle tone and resistance during passive movement.

What is the primary use of the Modified Ashworth Scale?

• To diagnose neurological disorders

• To evaluate joint flexibility

• To assess spasticity

• To measure muscle strength

In the MAS procedure, what is the initial position for assessing biceps spasticity?

• Elbow extension

• Wrist flexion

• Shoulder abduction

• Elbow flexion

What does a score of 0 on the MAS indicate?

• Moderate increase in muscle tone

• Considerable increase in muscle tone

• No increase in muscle tone

• Slight increase in muscle tone

How is a score of 1+ different from a score of 1 on the MAS?

• There is no catch in the range of motion

• The catch occurs earlier in the range of motion

• The catch occurs later in the range of motion

• The catch is more severe

What characterizes a score of 2 on the MAS?

• Considerable resistance throughout the range of motion

• Moderate resistance at the beginning of the range of motion

• Minimal resistance at the end of the range of motion

• No resistance throughout the range of motion

What does a score of 3 on the MAS indicate?

• Complete rigidity

• Considerable increase in muscle tone with difficulty moving to end range

• Moderate resistance at the beginning of the range of motion

• Slight increase in muscle tone

What is the characteristic of a score of 4 on the MAS?

• Complete rigidity with no movement possible

• Considerable increase in muscle tone

• Slight increase in muscle tone

• Moderate resistance throughout the range of motion
