Objectives To determine whether any intervention, with the specific aim o f maximising driving skills, improves the driving performa nce of people after stroke. Search methods WesearchedtheCochrane Stroke GroupTrialsregister(August 2 013), theCochrane Central Registerof ControlledTrials( The Cochrane Library 2012, Issue 3), MEDLINE (1950 to October 2013), EMBASE (1980 to Octo ber 2013), and six additional databases. To identify further published, unpublished and ongoing trial s, we handsearched relevant journals and conference proceeding s, searched trials and research registers, checked reference lists and conta cted key researchers in the area. Selection criteria Randomised controlled trials (RCTs), quasi-randomised trials and cluster studies of rehabilitation interventions, with t he specific aim of maximising driving skills or with an outcome of assessing d riving skills in adults after stroke. The primary outcome of i nterest was the performance in an on-road assessment after training. Secon dary outcomes included assessments of vision, cognition and dr iving behaviour. Data collection and analysis Two review authors independently selected trials based on pr e-defined inclusion criteria, extracted the data and assessed ri sk of bias. A third review author moderated disagreements as required. T he review authors contacted all investigators to obtain missi ng information. Main results We included four trials involving 245 participants in the revi ew. Study sample sizes were generally small, and interventi ons, controls and outcome measures varied, and thus it was inappropriate to pool studies. Included studies were at a low risk of bias for th e majority of domains, with a high/unclear risk of bias identified in the a reas of: performance (participants not blinded to allocation), a nd attrition (incomplete outcome data due to withdrawal) bias. Interventio n approaches included the contextual approach of driving simula tion and underlying skill development approach, including the ret raining of speed of visual processing and visual motor skills . The studies were conducted with people who were relatively young and the ti ming after stroke was varied. Primary outcome: there was no cle ar evidence of improved on-road scores immediately after trainin g in any of the four studies, or at six months (mean difference 15 points on the Test Ride for Investigating Practical Fitness to Drive - Belgian version, 95% confidence intervals (CI) 4.56 to 34.56, P v alue = 0.15, one study, 83 participants). Secondary outcomes: road sig n recognition was better in people who underwent training comp ared with control (mean difference 1.69 points on the Road Sign Recogn ition Task of the Stroke Driver Screening Assessment, 95% CI 0 .51 to 2.87, P value = 0.007, one study, 73 participants). Significan t findings were in favour of a simulator-based driving rehabil itation programme (based on one study with 73 participants) but these r esults should be interpreted with caution as they were based o n a single study. Adverse effects were not reported. There was insufficie nt evidence to draw conclusions on the effects on vision, other me asures of cognition, motor and functional activities, and driving beh aviour with the intervention. Authors’ conclusions There was insufficient evidence to reach conclusions about the use of rehabilitation to improve on-road driving skills after st roke. We found limited evidence that the use of a driving simulator m ay be beneficial in improving visuocognitive abilities, such as road sign recognition that are related to driving. Moreover, we we re unable to find any RCTs that evaluated on-road driving lesso ns as an intervention. At present, it is unclear which impairments tha t influence driving ability after stroke are amenable to rehab ilitation, and whether the contextual or remedial approaches, or a combinatio n of both, are more efficacious

Assessing functional impairment in individuals with mild cognitive impairment

To date, there is no consensus on how to assess functional impairment in individuals with mild cognitive impairment (MCI), and this lack of consensus is reflected in the clinical practice. Since the criterion used in the literature is very vague, clinicians are still left without much guidance in this area. Thus, the main goal of this study was to examine how functional impairment in individuals with MCI has been assessed in the literature. An electronic database search strategy was developed in consultation with an experienced librarian. Four databases (CINAHL, PsycINFO, PubMed, and MEDLINE) were searched from 2000 to May 2014 to provide a comprehensive coverage of the literature. The literature search yielded 14 tools that assessed functional impairment in MCI. Among those, nine tools were performance-based measures in which participants were observed while executing a task in a simulated environment using real life material. In terms of questionnaires (either informant- or self-reports), five tools were found. Different functional domains have been assessed in each tool. According to this review, the characteristics of the instruments used in the literature to assess functional impairment in individuals with MCI vary greatly. Nonetheless, results of this study allow clinicians to make better-informed decisions when choosing a functional assessment for this population
