Early Mobilisation Following Stroke

These people still don't understand that therapy after the stroke is not where research should take place. You stop the neuronal cascade of death and that will result in much less death and disability. Once again we see that nothing exists as standardized stroke protocols.  Why do I have to point out these fucking simplistic facts.

Stroke is a sudden loss of cerebral blood flow caused either by occlusion (85 % of cases) or rupture of the cerebral artery manifesting with focal neurological deficits.1 One-third of stroke patients are younger than and two-thirds are older than 65 years of age.2 Stroke can have both immediate and ongoing physical consequences. Disability and mortality represent the most relevant clinical outcomes. The degree of disability varies from devastating outcome with total dependence on family/carer to minimal and manageable disability.3 Within 12 months of stroke, one-third of stroke patients will die and another third are left with restriction in performing simple activities of daily living (ADL). Considering the high prevalence of the disease, the burden of post-stroke disability is of primary public health importance, translating to a substantial cost worldwide. In the US in 2008, for example, the direct and indirect costs of stroke are estimated to be more than $65 billion.4 Much of this cost probably relates to the physical disability. Any treatment that improves functional outcome can significantly reduce disability and costs, setting regaining of functional independence, defined as improvement in mobility and activities of ADL, as an important goal.4 The potential for recovery varies substantially across stroke patients. Factors associated with poor functional recovery include stroke severity, age and, to a lesser extent, diabetes.5

Today, rehabilitation is recognised as a cornerstone of multidisciplinary stroke care and can reduce the number of patients who are left handicapped. Forty per cent of stroke patients require active rehabilitation services.3 In recent years, rehabilitation has been shown to influence both brain recovery and reorganisation, especially in relation to motor impairment. Comprehensive rehabilitation programmes appear to improve functional recovery over standard care in terms of speed and extent of recovery.6 It is noteworthy that neurological recovery is not linear and most of it occurs within the first 3–6 months, although some patients show recovery over prolonged timelines.

Rehabilitation intensity depends on the status of the patient and degree of disability. If the patient is unconscious, rehabilitation is passive to prevent contractions, pressure ulcers and to prevent distress when movement is regained.3 However, there is still debate regarding the optimal intensity of physical therapy following stroke, with conflicting results across the different studies ranging from no benefit to significant functional improvement.6 This discrepancy may reflect differences in methodology, patient selection and outcome scales.


The Rationale Behind Very Early Mobilisation
Very early mobilisation (VEM) is a distinctive characteristic of care that involves starting mobilisation, including sitting up, getting out of bed, standing and walking, early after stroke and continuing at frequent intervals. However, the exact meaning of VEM is not well established and varies between 1 day to 3 months following symptoms onset.7

Previous studies have shown that induction of neurotrophic factors is associated with neural repair within the first 2 weeks after stroke and, thus, may modulate greater plasticity that may restore function in the periinfarct tissue and supplementary motor areas.8 This experience dependent cortical plasticity has been well documented in normal and injured brains.7 It may also enable the brain to better respond to rehabilitation, suggesting that efficacy of therapy may vary considerably with the timeline of initiation. The interaction between plasticity and recovery is, however, complicated and individualistic; therefore, it is of importance to apply the appropriate rehabilitation strategy at the appropriate time. Efforts are being made to develop more efficient rehabilitate strategies that utilise current knowledge of cortical plasticity. In addition to enhancing plasticity, VEM may prevent complications with a high risk of causing harm such as deep vein thrombosis, pulmonary embolism, contractures, infections, sores, muscle atrophy and deterioration in cardiorespiratory function. The complications associated with immobility were shown to be responsible for 51 % of deaths in patients with cerebral infarction.9 In another analysis of stroke unit systems,9 stroke unit care appeared to reduce complications of immobility, and infections, in particular. Early mobilisation may also have important psychological effects on a patient’s motivation, well-being and quality of life.6
