What good does doing research that only predicts failure to recover? SOLVE THE FUCKING PROBLEM OF 100% STROKE RECOVERY!
Stroke Rehabilitation: AB No: 124: Do Kinematic variables have an added advantage over clinical variables in Predicting Upper Extremity Motor Recovery Post-Stroke?
Purpose: Measurement of movement quality is essential to
distinguish motor recovery patterns and optimize rehabilitation
strategies post-stroke. The purpose of this study was to assess the
added advantage of kinematic over clinical measures for predicting
post-stroke upper extremity (UE) recovery by developing a regression
model comprising of both.
Relevance:
Meticulously formulated
prognostic models could be used by rehabilitation specialists for
improving prediction accuracy in stroke survivors.
Participants:
This study comprises of 89 acute to early sub-acute stroke survivors (58.8 ± 11.8 years, 61 males)
Methods:
Baseline characteristics, demographics, grip and pinch strength were
measured within 7 days and 3D kinematic analysis of a simulated drinking
task was performed within 1-month post-stroke. The sensorimotor
impairment through Fugl Meyer Assessment of Upper Extremity (FM-UE) was
assessed at 3-months. Kinematic metrics of time, displacement, velocity,
shoulder and elbow angles and reaction time were determined.
Results:
Clinical variables were available for 89 participants by 7 days and
kinematic for 50 individuals at 1 month. A strong correlation was found
between FM-UE at three months with Shoulder Abduction Finger Extension
(r=0.84), Nottingham Sensory Assessment (r=0.84), Motricity index
(r=0.82), National Institutes of Health Stroke Scale (r=0.75), and
moderate with pinch (r=0.69) and grip strength (r=0.62) measured within 7
days post-stroke. We found a weak correlation between FM-UE at 3 months
with velocity (r=0.53), time (r= -0.43) and displacement (r=0.38).
However, on combining clinical and kinematic variables the linear
regression model was found to have an R2 value of 0.85. Conclusion:
This model would help us predict impairment at 3 months for 85% stroke
survivors with similar characteristics. However, kinematic variables
should be used as an adjunct to clinical variables in order to
comprehensively predict UE recovery in stroke survivors.
Implications:
Predicting the amount of post-stroke recovery would enable us in
realistic goal formation (So you're trying to justify your use of the tyranny of low expectations as to why you can't get your patients recovered. I'd fire anyone using that excuse.)
) and for planning rehabilitation to improve
recovery potential.
