Formål og beskrivelse
The Modified Ashworth Scale bruges til at undersøge og angive graden af spasticitet på en skala fra 0-4. Skalaen ses nedenfor.
Der er ikken fundet en dansk version af The Modified Ashworth Scale.
0 No increase in muscle tone
1 Slight increase in muscle tone, manifested by a catch and release or minimal
resistance at the end ofthe range of movement (ROM) when the affected part
is moved in flexion or extension.
1+ Slight increase in muscle tone, manifested by a catch followed by minimal
resistance throughout theremainder (less than half) of the ROM.
2 More marked increase in muscle tone through most of the ROM, but
affected part easily moved.
3 Considerable increase in muscle tone, passive movement difficult.
4 Affected parts rigid in flexion and extension.

Vurdering
Ashworth Scale er ikke vurderet af Maaleredskaber.dk, men der findes flere eksterne undersøgelser, der indikerer, at der dels kan være problemer med reliabiliteten af Ashworth scale, dels, at Ashworth Scale måske i højere grad angiver hypertoni end spasticitet.
