A stake needs to be driven through the heart of proportional recovery and anyone researching it. Survivors don't want proportional recovery they want 100% recovery. ARE YOU THAT FUCKING STUPID!
Proportional recovery means your doctor, your hospital and your therapists have all completely failed you. They are normalizing failure.
Proportional Recovery After Stroke: Addressing Concerns Regarding Mathematical Coupling and Ceiling Effects
Abstract
Baseline
scores after stroke have long been known as a good predictor of
post-stroke outcomes. Similarly, the extent of baseline impairment has
been shown to strongly correlate with spontaneous recovery in the first 3
to 6 months after stroke, a principle known as proportional recovery.
However, recent critiques have proposed that proportional recovery is
confounded, most notably by mathematical coupling and ceiling effects,
and that it may not be a valid model for post-stroke recovery. This
article reviews the current understanding of proportional recovery after
stroke, discusses its supposed confounds of mathematical coupling and
ceiling effects, and comments on the validity and usefulness of
proportional recovery as a model for post-stroke recovery. We
demonstrate that mathematical coupling of the true measurement value is
not a real statistical confound, but rather a notational construct that
has no effect on the correlation itself. On the other hand, mathematical
coupling does apply to the measurement error and can spuriously amplify
correlation effect sizes, but should be negligible in most cases. We
also explain that compression toward ceiling and the corresponding
proportional recovery relationship are consistent with our understanding
of post-stroke recovery dynamics, rather than being unwanted confounds.
However, while proportional recovery is valid, it is not particularly
groundbreaking or meaningful as previously thought, just like how
correlations between baseline scores and outcomes are relatively common
in stroke research. Whether through proportional recovery or
baseline-outcome regression, baseline scores are a starting point for
investigating factors that determine recovery and outcomes after stroke.
