PREP2 algorithm predictions are correct at 2 years poststroke for most patients

So the OBVIOUS NEXT STEP  is to develop protocols that get patients fully recovered. This prediction crapola is useless for survivors.  clinicians may like it because then they can treat down to the tyranny of low expectations. 'This prediction says you will barely recover, so I'm done as soon as I minimally get you there.' Paraphrased, so don't shoot me.

Abstract: Study evaluated whether the PREP2 algorithm predictions made at baseline are correct 2 years post stroke and assessed whether patients’ upper-limb (UL) performance remained stable, improved, or worsened between 3 months and 2 years after stroke. The PREP2 algorithm combines clinical and neurophysiological measures to predict UL motor outcomes 3 months post stroke, using 4 prediction categories based on Action Research Arm Test (ARAT) scores. The algorithm was accurate at 3 months for 75 percent of participants in a previous validation study. This is a follow-up study of participants recruited and assessed in the original PREP2 validation study. One hundred fifty-seven participants who completed assessments 3 months post stroke were invited to complete follow-up assessments at 2 years poststroke for the present study. UL outcomes were assessed with the ARAT, upper extremity Fugl-Meyer Scale, and Motor Activity Log. A total of 86 participants completed 2-year follow-up assessments in this study. PREP2 predictions made at baseline were correct for 69/86 (80 percent) participants 2 years poststroke, and PREP2 UL outcome category was stable between 3 months and 2 years post stroke for 71 participants (83 percent). There was no difference in age, stroke severity, or comorbidities among patients whose category remained stable, improved, or deteriorated. The PREP2 algorithm predictions made within days of stroke are correct at both 3 months and 2 years poststroke for most patients. Further investigation may be useful to identify which patients are likely to improve, remain stable, or deteriorate between 3 months and 2 years.
