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 recovery5,6
It is possible to identify the functional risk factors that may contribute to the development of chronic spasticity.7
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 Post-Stroke Spasticity Classification System was created with the assistance of a group of international experts in the field of PSS, utilising both published risk factors and their own clinical experience.
The development of this material was funded by AbbVie.
This tool is recommended by experts in the field of stroke rehabilitation and neurorehabilitation to be used when evaluating patients who have had a stroke, ideally within the first 12 weeks post-stroke. However, it can still be used at other timepoints. It is recommended that this screening tool is used during regular follow-up visits after a stroke, to identify and manage symptoms of post-stroke spasticity.
Possible additional risk factors for the development of post-stroke spasticity include:
- smoking (defined as current and past smokers)9,18
- left-sided stroke9
- enhanced manual activities prior to the stroke9
This tool is based on the clinical expertise of Dr Rhoda Allison, Dr Ganesh Bavikatte, Professor Philippe Marque, Associate Professor Barry Rawicki, Dr Maria Matilde de Mello Sposito, Dr Paul Winston and Professor Jörg Wissel.
*Mildly increased muscle stiffness = MAS 1 or +1; moderately = MAS 2; markedly = MAS 3; severe = MAS 4.‡19 †Measured using the Fugl-Meyer Upper Extremity Scale.10,11 ‡Based on the clinical expertise of the expert panel. §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).9
