Spasticity of the [insert muscle group, e.g., elbow flexors/plantar flexors] was assessed using the Modified Ashworth Scale (MAS). The MAS is a clinical tool used to measure the resistance of a muscle to passive stretch at a constant velocity. The scale consists of six scoring levels:
0: No increase in muscle tone.
1: Slight increase in muscle tone, manifested by a catch and release or minimal resistance at the end of the range of motion (ROM).
1+: Slight increase in muscle tone, manifested by a catch, followed by minimal resistance throughout the remainder (less than half) of the ROM.
2: More marked increase in muscle tone through most of the ROM, but affected part(s) easily moved.
3: Considerable increase in muscle tone, passive movement difficult.
4: Affected part(s) rigid in flexion or extension.
