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 various muscles, such as the biceps brachii and quadriceps, and explains the scoring system from 0 to 4, with 0 indicating no spasticity and 4 indicating rigidity. Each score level is demonstrated, highlighting the differences in muscle tone and resistance.

What is the primary use of the Modified Ashworth Scale?

• To measure muscle strength

• To assess muscle resistance to passive movement

• To evaluate joint flexibility

• To diagnose neurological disorders

In the assessment of spasticity using the MAS, what is the initial position of the muscle?

• Partially flexed

• Maximally lengthened

• Neutral position

• Maximally shortened

What does a score of 0 on the MAS indicate?

• Moderate resistance

• Complete rigidity

• Slight increase in muscle tone

• No increase in muscle tone

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

• 1+ indicates no resistance

• 1+ indicates resistance at mid-range

• 1+ indicates complete rigidity

• 1+ indicates resistance at end-range

What characterizes a score of 2 on the MAS?

• No resistance

• Slight resistance at end-range

• Moderate resistance throughout most of the range

• Complete rigidity

What does a score of 3 on the MAS signify?

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

• No increase in muscle tone

• Complete rigidity

• Slight resistance at mid-range

What does a score of 4 on the MAS indicate?

• Slight increase in muscle tone

• Moderate resistance

• Complete rigidity

• Considerable increase in muscle tone
