Canadian Stroke Best Practice Recommendations: Rehabilitation, Recovery, and Community Participation following Stroke. 6th Edition Update 2019.

The sixth update of the is a comprehensive set of evidence-based guidelines addressing issues surrounding impairments, activity limitations, and participation restrictions following stroke. Rehabilitation is a critical component of recovery, essential for helping patients to regain lost skills, relearn tasks, and regain independence. Following a stroke, many people typically require rehabilitation for persisting deficits related to hemiparesis, upper-limb dysfunction, pain, impaired balance, swallowing, and vision, neglect, and limitations with mobility, activities of daily living, and communication.

Building a Bridge to the Community: An Integrated Knowledge Translation Approach to Improving Participation in Community-Based Exercise for People After Stroke.

Background: People who have had a stroke and are living in the community have low levels of physical activity, which reduces their functional capacity and increases risks of developing secondary comorbid conditions. Exercise delivered in community centers can address these low levels of physical activity; however, implementing evidence-based programs to meet the needs of all community stakeholders is challenging.

Objectives: The objective of this study was to determine implementation factors to facilitate participation in relevant exercise and physical activity for people with chronic health conditions, like stroke.

Intracellular selection of peptide inhibitors that target disulphide-bridged Aβ42 oligomers.

The β-amyloid (Aβ) peptide aggregates into a number of soluble and insoluble forms, with soluble oligomers thought to be the primary factor implicated in Alzheimer's disease pathology. As a result, a wide range of potential aggregation inhibitors have been developed. However, in addition to problems with solubility and protease susceptibility, many have inadvertently raised the concentration of these soluble neurotoxic species.

Retro-inversal of intracellular selected β-amyloid-interacting peptides: implications for a novel Alzheimer's disease treatment.

The aggregation of β-amyloid (Aβ) into toxic oligomers is a hallmark of Alzheimer's disease pathology. Here we present a novel approach for the development of peptides capable of preventing amyloid aggregation based upon the previous selection of natural all-l peptides that bind Aβ1-42. Using an intracellular selection system, successful library members were further screened via competition selection to identify the most effective peptides capable of reducing amyloid levels.

Combining intracellular selection with protein-fragment complementation to derive Aβ interacting peptides.

Aggregation of the β-amyloid (Aβ) peptide into toxic oligomers is considered the primary event in the pathogenesis of Alzheimer's disease. Previously generated peptides and mimetics designed to bind to amyloid fibrils have encountered problems in solubility, protease susceptibility and the population of small soluble toxic oligomers. We present a new method that opens the possibility of deriving new amyloid inhibitors.

Role of the primary somatosensory cortex in motor learning: An rTMS study.

Somatosensation is thought to play an important role in skilled motor learning. The present study investigated how healthy adults learn a continuous implicit motor task when somatosensation is altered by 1 Hz repetitive transcranial magnetic stimulation (rTMS) delivered over the primary somatosensory cortex (S1). Twenty-seven right-handed participants enrolled in a two-part experiment.

Stroke, complex regional pain syndrome and phantom limb pain: can commonalities direct future management?

Despite being different conditions, complex regional pain syndrome type 1, phantom limb pain and stroke share some potentially important similarities. This report examines experimental and clinical findings from each patient population. It identifies common aspects of symptomatic presentation, sensory phenomena and patterns of cortical reorganization.

Dysynchiria: watching the mirror image of the unaffected limb elicits pain on the affected side.

People with complex regional pain syndrome type 1 (CRPS1) watched a reflected image of their unaffected limb being touched and felt pain or paresthesia at the corresponding site on the affected limb. The authors suggest that allodynia and paresthesia can be mediated by the brain and that dysynchiria has implications for the understanding and management of CRPS1.
