A Review Of Transcranial Magnetic Stimulation And Multimodal Neuroimaging To Characterize Post-Stroke Neuroplasticity, Angela M. Auriat, Jason L. Neva, Sue Peters, Lara A. Boyd

Physical Therapy Publications

Following stroke, the brain undergoes various stages of recovery where the central nervous system can reorganize neural circuitry (neuroplasticity) both spontaneously and with the aid of behavioral rehabilitation and non-invasive brain stimulation. Multiple neuroimaging techniques can characterize common structural and functional stroke-related deficits, and importantly, help predict recovery of function. Diffusion tensor imaging (DTI) typically reveals increased overall diffusivity throughout the brain following stroke, and is capable of indexing the extent of white matter damage. Magnetic resonance spectroscopy (MRS) provides an index of metabolic changes in surviving neural tissue after stroke, serving as a marker of brain function. The neural …

Motor And Visuospatial Attention And Motor Planning After Stroke: Considerations For The Rehabilitation Of Standing Balance And Gait, Sue Peters, Todd C. Handy, Bimal Lakhani, Lara A. Boyd, S. Jayne Garland

Physical Therapy Publications

Attention and planning can be altered by stroke, which can influence motor performance. Although the influence of these factors on recovery from stroke has been explored for the upper extremity (UE), their impact on balance and gait are unknown. This perspective article presents evidence that altered motor and visuospatial attention influence motor planning of voluntary goal-directed movements poststroke, potentially affecting balance and gait. Additionally, specific strategies for rehabilitation of balance and gait poststroke in the presence of these factors are discussed. Visuospatial attention selects relevant sensory information and supports the preparation of responses to this information. Motor attentional impairments may …

Mobility And Cognition In Seniors. Report From The 2008 Institute Of Aging (Cihr) Mobility And Cognition Workshop, Manuel Montero-Odasso, Louis Bherer, Stephanie Studenski, Karen Gopaul, Afua Oteng-Amoako, Sarah Woolmore-Goodwin, Paul Stoole, Jennie Wells, Timothy Doherty, Aleksandra A. Zecevic, David Galinsky, R. Jane Rylett, Jeffrey Jutai, Susan W. Muir-Hunter, Mark Speechley, Richard Camicioli

Physical Therapy Publications

Background

The annual Scientific Meeting of the Canadian Association on Gerontology was held on October 24 and 25, 2008 in London, Ontario. Prior to the annual meeting, mobility and cognition experts met on October 23, 2008 to engage in a pre-conference workshop.

Methods

Discussions during the workshop addressed novel areas of research and knowledge and research gaps pertaining to the interaction between mobility and cognition in seniors.

Results

Workshop presenters moved from the neuromuscular, biomechanics, and neurology of gait impairments, and falls through the role of cognition and mood on mobility regulation to the whole person in the environment. Research …

Reliability Of The Berg Balance Scale As A Clinical Measure Of Balance In Community-Dwelling Older Adults With Mild To Moderate Alzheimer Disease: A Pilot Study, Susan W Muir-Hunter, Laura J. Graham, Manuel Montero Odasso

Physical Therapy Publications

Purpose : To measure test-retest and interrater reliability of the Berg Balance Scale (BBS) in community-dwelling adults with mild to moderate Alzheimer disease (AD).

Method : A sample of 15 adults (mean age 80.20 [SD 5.03] years) with AD performed three balance tests: the BBS, timed up-and-go test (TUG), and Functional Reach Test (FRT). Both relative reliability, using the intra-class correlation coefficient (ICC), and absolute reliability, using standard error of measurement (SEM) and minimal detectable change (MDC95) values, were calculated; Bland-Altman plots were constructed to evaluate inter-tester agreement. The test-retest interval was 1 week.

Results : For the BBS, relative …

Short-Term Cortical Plasticity Associated With Feedback-Error Learning After Locomotor Training In A Patient With Incomplete Spinal Cord Injury, Amanda E. Chisholm, Sue Peters, Michael R. Borich, Lara A. Boyd, Tania Lam

Physical Therapy Publications

Background and purpose: For rehabilitation strategies to be effective, training should be based on principles of motor learning, such as feedback-error learning, that facilitate adaptive processes in the nervous system by inducing errors and recalibration of sensory and motor systems. This case report suggests that locomotor resistance training can enhance somatosensory and corticospinal excitability and modulate resting-state brain functional connectivity in a patient with motor-incomplete spinal cord injury (SCI).

Case description: The short-term cortical plasticity of a 31-year-old man who had sustained an incomplete SCI 9.5 years previously was explored in response to body-weight-supported treadmill training with velocity-dependent resistance applied …

The Manual Ability Classification System: A Scoping Review, Deepa Jeevanantham, Emily Dyszuk, Doreen Bartlett

Physical Therapy Publications

PURPOSE: To examine the use of the Manual Ability Classification System (MACS) and to identify gaps in the literature by conducting a thorough search of existing publications from 2006 to March 2013.

METHODS: An extensive literature search included 15 databases, using the search terms "Manual Ability Classification System" or "MACS" to retrieve relevant abstracts.

RESULTS: A total of 161 articles were identified for final inclusion. The review identified literature that supports the reliability, validity, and stability of the MACS.

CONCLUSIONS: The MACS could be considered as a standard classification for children with cerebral palsy on the basis of manual abilities. …
