Background:
Contraversive lateropulsion is a common post-stroke impairment. Rehabilitation outcomes in stroke survivors exhibiting lateropulsion may differ from those without lateropulsion.
Objectives:
To systematically review evidence regarding associations between:1. Presence/severity of lateropulsion after stroke and functional outcome, rehabilitation length of stay, and discharge destination;2. Stroke-related factors and resolution of lateropulsion, functional outcome, rehabilitation length of stay, and discharge destination in affected stroke survivors.
Methods:
Medline, CINAHL, and Embase databases were searched. Journal articles published in English reporting on resolution of lateropulsion, length of stay, functional outcome, and/or discharge destination associated with post-stroke lateropulsion were included for review. Studies that did not include a comparison group (stroke survivors without lateropulsion, or sub-groups of participants with lateropulsion based on stroke-related factors), animal studies, and studies reporting only on ipsiversive lateropulsion and/or lateral medullary syndrome were excluded. Two authors independently assessed studies for inclusion. Included studies were evaluated using the Risk of Bias Assessment Tool for Nonrandomized Studies.
Results:
Screening identified 133 articles. Seven articles met inclusion criteria. People with contraversive lateropulsion after stroke can achieve similar improvements in function as those without lateropulsion, increasing likelihood of discharge home, but require longer rehabilitation durations to do so.
Conclusions:
The finding that longer rehabilitation durations are required for people with post-stroke lateropulsion to achieve their functional potential and increase likelihood of discharge home has implications for resourcing rehabilitation services. Given an additional three to four weeks in rehabilitation, people with post-stroke lateropulsion can achieve functional improvements function similar to those without lateropulsion.
