You have received the results of all the assessments that were performed on Marie.

Ashworth Scale and Tardieu Scale

Spasticity was assessed using the Ashworth Scale (reference international scale) and the Tardieu Scale (gives the ‘spasticity angle’ and the ‘paresis angle’, which are more sensitive to change). Spasticity was graded as follows:

• Wrist Flexors: A1 T1 130/90/120 (neutral position is 90°)
• Finger Flexors: A2 T2 200/90/130 (neutral position is 180°)

Finochietto Test

The Finochietto Test helps to differentiate extrinsic and intrinsic hand muscle spasticity and shortening.

Box and Block Test with Video Recording

The Box and Block Test is used to test functioning.

Post-stroke Spasticity Referral Tool

Using the information about Stefan and his wife’s goals, the results of the clinical assessment and everything you have learned from him and his wife, you decide to determine the next course of action using the

Post-stroke Spasticity Referral Tool


 


Post-stroke Spasticity (PSS) Referral Tool

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, this should be used within the first 12 weeks post-stroke, but it can still be used at other timepoints. It is recommended that this screening tool be used during regular follow-up visits following a stroke to identify and manage the symptoms of PSS.
 


Possible additional risk factors for the development of PSS include:

Smoking (defined as current and past smokers)8,18 | Left-sided stroke8 | Enhanced manual activities prior to the stroke8
*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 & Professor Jörg Wissel.

Case Conclusion
 


PSS, post-stroke spasticity.



 


aMildly increased muscle stiffness is a Modified Ashworth Scale (MAS) 1 or +1, while moderately is MAS 2, markedly is MAS 3, and severe is MAS 4* (see Bohannon RW, et al. 1987 for more information19).
bMeasured using the Fugl-Meyer Upper Extremity Scale3 (see Fugl-Meyer AR, et al. 1975 for more information11).
cMuscle contractions may occur due to spasms, disturbed reciprocal inhibition, or spastic dystonia and should be differentiated from contractures
dVisual inattention includes hemianopsia, scotoma, or visual neglect.
eCan be measured with the Barthel Index (low score) and EQ-5D (low score).8
The PSS Referral Tool 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.
