Although the Ashworth Scale is widely used, it has some limitations. One major issue is its subjectivity, as the assessment relies heavily on the examiner's perception of resistance. This can lead to variability between different examiners. Additionally, the scale does not differentiate between different types of hypertonia (e.g., spasticity vs. rigidity), nor does it comprehensively evaluate the functional impact of spasticity on the patient’s daily life.
