Algorithm predictions

Predicted outcome	Description	Rehabilitation focus
Excellent	Potential to make a complete, or near‐complete, recovery of hand and arm function within 3 months	Promote normal use of the affected hand and arm with task‐specific practice, while minimizing adaptation and compensation.
Good	Potential to be using the affected hand and arm for most activities of daily living within 3 months, though with some weakness, slowness, or clumsiness	Promote normal function of the affected hand and arm by improving strength, coordination, and fine motor control with repetitive and task‐specific practice. Minimize compensation with the other hand and arm, and the trunk.
Limited	Potential to regain movement in the affected hand and arm within 3 months, but daily activities are likely to require significant modification	Promote movement and reduce impairment by improving strengthand active range of motion. Promote adaptation in daily activities, incorporating the affected upper limb wherever safely possible.
Poor	Unlikely to regain useful movement of the hand and arm within 3 months	Prevent secondary complications such as pain, spasticity, and shoulder instability. Reduce disability by learning to complete daily activities with the stronger hand and arm.

Note that the outcome category names replace those used in the original PREP algorithm (Complete, Notable, Limited, None).
