Stroke recovery

[3] Current research suggests that stroke units may be effective in reducing in-hospital fatality rates and the length of hospital stays.

[2] The initial severity of impairments and individual characteristics, such as motivation, social support, and learning ability, are key predictors of stroke recovery outcomes.

[citation needed] "Neurocognitive Rehabilitation by Carlo Perfetti concept", widespread in many countries, is an original motor re-learning theories application.

[10] Evidence that supports the use of constraint induced movement therapy has been growing since its introduction as an alternative treatment method for upper limb motor deficits found in stroke populations.

[11] Recently, constraint induced movement therapy has been shown to be an effective rehabilitation technique at varying stages of stroke recovery to improve upper limb motor function and use during activities of daily living.

However, there is no established causal link between observed changes in brain function/structure and the motor gains due to constraint induced movement therapy.

[17][unreliable medical source] Mental practice of movements, has been shown in many studies to be effective in promoting recovery of both arm and leg function after a stroke.

[19][unreliable medical source] Such work represents a paradigm shift in the approach towards rehabilitation of the stroke-injured brain away from pharmacologic flooding of neuronal receptors and instead, towards targeted physiologic stimulation.

[26]Robot-assisted training enables stroke patients with moderate or severe upper limb impairment to perform repetitive tasks in a highly consistent manner, tailored to their motor abilities.

High intensity repetitive task practice delivered via robot-assisted therapy is recommended to improve motor function in individuals in the inpatient, outpatient and chronic care settings.

These findings have led to MSCs being considered for treatment of ischemic stroke,[40] specifically in directly enhancing neuroprotection and the neurorestorative processes of neurogenesis, angiogenesis and synaptic plasticity.

[citation needed] Induction of neurogenesis (development of new neurons) is another possible mechanism of neurorestoration; however its correlation with functional improvement after stroke is not well established.

MSC treatment also has shown to have various neuroprotective effects,[37] including reductions in apoptosis,[44] inflammation and demyelination, as well as increased astrocyte survival rates.

[40] If MSC treatment becomes available for stroke patients, it is possible that current mortality and morbidity rates could substantially improve due to the direct enhancement of neuroprotection and neurorestoration mechanisms rather than only indirect facilitation or prevention of further damage, e.g. decompressive surgery.

[60] The changes in muscle tone probably result from alterations in the balance of inputs from reticulospinal and other descending pathways to the motor and interneuronal circuits of the spinal cord, and the absence of an intact corticospinal system.

[77] Surgical treatment for spasticity includes lengthening or releasing of muscle and tendons, procedures involving bones, and also selective dorsal rhizotomy.

This altered perception of stimuli, or allodynia, can be difficult to assess due to the fact that the pain can change daily in description and location, and can appear anywhere from months to years after the stroke.

Affected persons may describe the pain as cramping, burning, crushing, shooting, pins and needles, and even bloating or urinary urgency.

Several strategies have been employed by physicians, including intravenous lidocaine, opioids/narcotics, anti-depressants, anti-epileptic medications and neurosurgical procedures with varying success.

[81] Possible causes may include shoulder subluxation, muscle contractures, spasticity, rotator cuff disorders or impingement, and complex regional pain syndrome.

[27] However, the use of slings remains controversial and may increase the risk of adverse effects on symmetry and balance between the left and right shoulders, and can impact peoples' body image.

To provide a high level of mobility the shoulder sacrifices ligamentous stability and as a result relies on the surrounding musculature (i.e., rotator cuff muscles, latissimus dorsi, and deltoid) for much of its support.

A sling may also contribute to contractures and increased flexor tone if used for extended periods of time as it places the arm close to the body in adduction, internal rotation and elbow flexion.

[94] The findings are based on low-quality evidence as further research is needed to estimate the effect of MI on walking endurance and the dependence on personal assistance.

This condition was initially recognized as: 'Disorders of the execution of learned movements which cannot be accounted for by either weakness, incoordination, or sensory loss, nor by incomprehension of, or inattention to commands.

The National Institute of Neurological Disorders and Stroke (NINDS) is currently sponsoring a clinical trial to gain an understanding of how the brain operates while carrying out and controlling voluntary motor movements in normal subjects.

Other psychological factors can lead to the development of depression including personal and social losses related to the physical disabilities often caused by a stroke.

More recently, the selective serotonin reuptake inhibitors (SSRIs), such as fluoxetine and citalopram, have become the pharmacologic therapy of choice due to the lower incidence of side effects.

For this reason, scientific teams have been trying to develop a reliable transfer package that could be used to train and improve instrumental activities of daily living.
