Early mobilization after stroke: early adoption but limited evidence.

Abstract

In the last decade, increasing attention has been paid to understanding the components of care that might contribute to the stroke unit effect. Early mobilization, in its many guises, is one component of care proposed to contribute to the survival and recovery benefits of stroke unit care.1 This topical review provides an overview of the current evidence, research, and practice recommendations for early mobilization after stroke. As a term, early mobilization is problematic. There is no common understanding of the meaning of early (eg, hours, days, weeks, months) or mobilization (movement of, eg, cells, joints, limbs, people). A recurring theme in this review, inadequate definition currently limits our ability to synthesize information on the topic. For example, in some clinical trials of mobility interventions started soon after stroke, mobilization is used to describe a program of task-specific standing and walking retraining (rehabilitation) delivered by therapists or nurses and continued throughout the acute hospital stay.2,3 In other cases, mobilization refers simply to moving a patients’ limbs in bed or sitting them out of bed. The timing of commencement of activity is also highly variable and often hard to determine. As both what we do (intervention type, intensity, frequency, amount), and when we do it, may confer benefit or harm, we highlight variations in definition where relevant. We have focused our review on out-of-bed interventions commencing in the first 24 to 72 hours after stroke, as this is the period of greatest clinical uncertainty. Early mobilization was first discussed at a Swedish consensus conference on stroke care in the mid-1980s (Bo Norving and Bent Indredavik, personal communication, 2014) with several local guidelines in Norway and Sweden recommending the practice. Early mobilization became more prominent in the literature in the early 1990s when Indredavik and colleagues reported their clinical …
