Introduction

  • The Modified Ashworth Scale (MAS) is an important clinical tool used to measure muscle tone, specifically spasticity, in paediatric patients.
  • Spasticity is defined as velocity-dependent resistance to passive movement, commonly seen in children with cerebral palsy (CP) and other neurological conditions.
  • Originally developed from the Ashworth Scale, the Modified Ashworth Scale is widely used due to its simplicity, ease of administration, and reliability.

Historical Context

  • Initially developed by Bryan Ashworth in 1964.
  • Modified in 1987 by Bohannon and Smith to improve sensitivity and clinical usability, especially for paediatric populations.

Purpose and Clinical Application

  • To assess the degree of spasticity (hypertonia) in limbs.
  • Guides clinical decision-making, including therapeutic interventions such as physiotherapy, botulinum toxin injections, baclofen therapy, and surgical interventions.
  • Helps monitor progression or response to treatments over time.
