How to diagnose post-stroke spasticity (PSS)
Diagnosis and treatment of PSS during the first 3 months post-stroke may benefit patients in their aim for a full recovery6, 7
It is possible to identify the functional risk factors that may contribute to the development of chronic spasticity.8
The PSS risk classification tool has been developed by a panel of experts and AbbVie to help spasticity patients get the timely treatment they need
The PSS Classification System was created with the assistance of a group of International experts in the field of PSS and AbbVie, utilising both published risk factors and their own clinical experience9

*Mildly increased muscle stiffness = Modified Ashworth Scale (MAS) 1 or +1; moderately = MAS 2; markedly = MAS 3; severe = MAS 4.19 †Measured using the Fugl-Meyer Upper Extremity Scale.12 ‡Muscle contractions should be differentiated from contractures. §Visual inattention includes hemianopsia, scotoma or visual neglect. **Can be measured with the Barthel Index (low score) and EQ-5D (low score).11
Possible additional risk factors for the development of post-stroke spasticity include:
- smoking (defined as current and past smokers)11,13
- left-sided stroke11
- enhanced manual activities prior to the stroke11
CT: computerised tomography; EQ-5D: EuroQol-5D; MAS: Modified Ashworth Scale; MDT: multidisciplinary team; MRI: magnetic resonance imaging; PSS: post-stroke spasticity.
