Application of the p9NORM correction method to timed neuropsychological tests in Parkinson's disease and multiple system atrophy.

Objective: Timed neuropsychological tests do not take into account physical impairment during scoring procedures. Dysarthria and upper limb impairment can be easily measured with the PATA rate test (PRT) and the nine-hole pegboard test (9HPT). We recently validated a normalization method for timed neuropsychological tests using the PRT and 9HPT (p9NORM).

Adult normative values for the PATA Rate Test.

Background: During neurological evaluation, dysarthria is not rated using quantitative measures, but rather using a qualitative approach.

Objective: Aim of our study was to validate and acquire normative values for the PATA Rate Task (PRT), a quantitative test used to measure the severity of dysarthria.

Methods: For the PRT probands are invited to repeat the syllables "PA-TA" as quickly as possible during a 10-s interval.
