The Modified Ashworth Scale (MAS) is a revised version of the original Ashworth Scale that measures spasticity in patients with lesions to the central nervous system. MAS is an assessment that is used to measure the increase in muscle tone. MAS assigns a grade of spasticity from a 0-4 ordinal scale. The modified Ashworth scale is the most universally accepted clinical tool used to measure the increase of muscle tone. [1] Spasticity was defined by Jim Lance in 1980, as a velocity-dependent increase in muscle stretch reflexes associated with increased muscle tone as a component of upper motor neuron syndrome.
Muscle Tone Modified Ashworth Scale
Modified Ashworth Scale (MAS) is used to assess spasticity. [1] Intended Population Modified Ashworth Scale (MAS) have been utilized in the following populations: stroke, spinal cord injury, multiple sclerosis, cerebral palsy, traumatic brain injury, pediatric hypertonia and central nervous system lesions [2] Method of Use Description Modified Ashworth Scale Instructions General Information (derived Bohannon and Smith, 1987): Place the patient in a supine position If testing a muscle that primarily flexes a joint, place the joint in a maximally flexed position and move to a position of maximal extension over one second (count "one thousand one") The Modified Ashworth scale ( MAS) measures resistance during passive soft-tissue stretching and is used as a simple measure of spasticity. [1] Scoring (taken from Bohannon and Smith, 1987): 0: No increase in muscle tone The Modified Ashworth Scale is considered the primary clinical measure of muscle spasticity in patients with neurological conditions. However, some publications question its ability to measure spasticity

The modified Ashworth scale is the most universally accepted clinical tool used to measure the increase of muscle tone. Spasticity was defined by Jim Lance in 1980, as a velocity-dependent increase in muscle stretch reflexes associated with increased muscle tone as a component of upper motor neuron. Patient Care Evidence-Based Practice Resources Tests and Measures Ashworth Scale (AS) and Modified Ashworth Scale (MAS) Ashworth Scale (AS) and Modified Ashworth Scale (MAS) Tests & Measures Summary What it measures: Both the Ashworth Scale (AS) and Modified Ashworth Scale (MAS) are used to assess spasticity. Target Population: The modified Ashworth scale purpose is to grade muscle spasticity. The scale is as follows [4]: 0: No increase in muscle tone 1: Slight increase in muscle tone, with a catch and release or minimal resistance at the end of the range of motion when an affected part (s) is moved in flexion or extension PMID: 23166123 Comparing the validity of the Modified Modified Ashworth Scale (MMAS) and the Modified Tardieu Scale (MTS) in the assessment of wrist flexor spasticity in patients with stroke: protocol for a neurophysiological study

Shop the Catalyst University store In this video, we explore the grading on the Modified Ashworth Scale (MAS), so that you understand how to grade a patient's spasticity.What is Spasticity? |. The Modified Ashworth Scale is a frequently used tool among Physiatrists, Neurologists, Physical therapists, and Occupational Therapists to classify the degree of spasticity and increased muscle tone in patients with upper motor neuron syndromes. It is commonly applied in patients with Stroke, Spinal Cord Injury and Traumatic Brain injury.
M o d i f i e d A s h wo r t h S c a l e ( M A S ) Grade Description 0 No increase in muscle tone 1 Slight increase in muscle tone, manifested by a catch The Modified Ashworth Scale (MAS) is the most widely used clinical tool for the measurement of spasticity. However, its reliability has been questioned in some studies [4,5,6]. In children with spastic CP or hypertonia, the reliability of MAS varied across studies [7,8,9,10].

The modified Ashworth scale is the most universally accepted clinical tool used to measure the increase of muscle tone. Spasticity was defined by Jim Lance in 1980, as a velocity-dependent increase in muscle stretch reflexes associated with increased muscle tone as a component of upper motor neuron syndrome. Spasticity has a wide range of. The Modified Ashworth Scale (MAS) is a measure of muscle spasticity. It was developed in 1982 by Dr Timothy A. Pedley and Dr David N. Simpson. The scale is used to rate the level of muscle tightness or spasm from 0 (no increase in muscle tone) to 4 (affected limb rigid in flexion or extension).
