Systematic review of outcome measures of walking training using electromechanical and robotic devices in patients with stroke

The aim of this systematic review was to identify appropriate selection criteria of clinical scales for future trials, starting from those most commonly reported in the literature, according to their psychometric properties and International Classification of Functioning, Disability and Health (ICF) domains. A computerized literature research of articles was conducted in MEDLINE, EMBASE, CINALH, PubMed, PsychINFO and Scopus databases. Clinical trials evaluating the effects of electromechanical and robot-assisted gait training trials in stroke survivors. Fifteen independent authors performed an extensive literature review. A total of 45 scales was identified from 27 studies involving 966 subjects. The most commonly used outcome measures were: Functional Ambulation Category (18 studies), 10-Meter Walking Test (13 studies), Motricity Index (12 studies), 6-Minute Walking Test (11 studies), Rivermead Mobility Index (8 studies) and Berg Balance Scale (8 studies). According to the ICF domains 1 outcome measure was categorized into Body Function and Structure, 5 into Activity and none into Participation. The most commonly used scales evaluated the basic components of walking. Future studies should also include instrumental evaluation. Criteria for scale selection should be based on the ICF framework, psychometric properties and patient characteristics.
