Outcome measures
Primary outcome
Primairy outcome is the Short Range Stiffness, which is compared between the
patient group and the control group.
Secondary outcome
The secundaire outcome within the patient group is the clinical defined wrist
stiffnes, instrumented by the modified Ashworth Scale (mAS) and the Tardieu
Scale (TS). The clinical outcome will be related to the Short Range Stiffness
Background summary
Altered joint stiffness i.e. in the wrist after a stroke can lead to problems
in daily functioning. For treatment is necessary to identify the cause of the
stiffness. This can either be passive connective tissue, reflexive or muscular
stiffness. By determining the Short Range Stiffness (SRS) the contribution of
muscular stiffness can be separated from the passive (connective tissue)
component and the reflective component.
Study objective
The Primary objective is to quantify the Short Range Stiffness dynamics after
stroke in order to quantify the tonic muscle co-activation.
Study design
This study is an observational case-control study. The Short Range Stiffnessis
measured in both the patient group and the control group. For the patient group
additionally two clinical tests will be perform, the Modified Asworth Scale
(MAS) and Tardie Scale (TS). The duration of one session lasts 60 and 90
minutes for controls and patients respectively.
Study burden and risks
The burden of the study is low. All participants must perform a light isometric
force and a movement within their range of motion. In addition, the clinical
tests are performed passively by the examiner again within the range of motion.
There are are no known risks with the measurement of SRS and also no known
risks with the clinical tests .
