The PSFS is measured on an 11 point scale, 0 being unable to complete task and 10 being able to complete at a level prior to injury on five to seven different functional task the patient chooses. The Rivermead is made up of 15 set activities with specific instructions and the patient is either scored a 0 or 1 depending on if they could complete the task following the exact directions. Most importantly which tests will be able to provide the best information? When looking at reliability the Rivermead had excellent test-retest reliability (ICC = 0.99) and the PSFS had excellent interrater reliability (ICC = 0.83), both were examined for reliability but indifferent ways the Rivermead looked at if the patient took the test two different times how closely would the result match and the PSFS looked at if two different testers administered the test how would the results compare, both test are considered excellent for reliability but would measured differently so they cannot be perfectly compared. When looking at the validity of the two
