Symptom and performance validity in neuropsychological assessments of outpatients 15-30 years of age.

Objective: It has been suggested that performance validity tests (PVTs) assess the credibility of a patient's objective test performance, symptom validity tests (SVTs) assess the credibility of a patient's subjective complaints, and that PVTs and SVTs are independent measures. The aim of this study was to test this hypothesis and investigate the associations of PVTs and SVTs with cognitive tests and self-reported measures.

Method: Patients 15-30 years of age were consecutively recruited from a neurorehabilitation outpatient clinic.

Cognitive status does not predict motor gain from post stroke constraint-induced movement therapy.

Background: Constraint-Induced Movement Therapy (CIMT) is an evidence-based rehabilitation intervention for stroke. Several factors influence the motor gain from CIMT, including age and level of impairment. However, it is currently unknown to what extent cognitive status affects motor gain during CIMT.
