Abstract

Introduction
Adapted from the Wolf Motor Function Test, the graded Wolf Motor Function Test is an upper limb activity assessment for use following stroke and brain injury. The aim of this systematic review was to identify and appraise evidence where the test has been used or has undergone psychometric evaluation.

Method
A systematic review of five databases was conducted to identify studies reporting the graded Wolf Motor Function Test using a keyword search. Intervention and clinical measurement studies were eligible for inclusion. Data quality was assessed using the adapted Critical Appraisal Skills Programme questions and the Consensus-based Standards for the Selection of Health Measurement Instruments Risk of Bias checklist.

Results
Twelve studies, of mostly low quality, were included. Studies included one randomised controlled trial, 10 pre- and post-studies and one clinical measurement study. All studies involved participants following stroke. Reliability was the only measurement property assessed in two studies, which were of a ‘doubtful’ and ‘poor’ quality.

Conclusion
Low quality studies impede the ability of clinicians and researchers to best determine the applicability of the graded Wolf Motor Function Test to patient groups and research contexts. Further exploration of the psychometric properties of the graded Wolf Motor Function Test is recommended across stroke populations using rigorous design methods.
