Chronic hemiparetic stroke individuals are at a higher risk of falling. This may be due to balance impairments, cardiovascular deconditioning, and muscle weakness associated with stroke effects. Postural instability associated with fatigue would likely be attained more rapidly for stroke individuals than for healthy individuals. Objective: To determine the effects of physical exertion induced by walking on postural stability in hemiparetic stroke participants. Methods: Twelve hemiparetic participants and 12 control participants walked over-ground for a duration of 6. min and 18. min at their comfortable speed. Postural stability was assessed using centre of pressure related parameters during double-legged stance and tasks before the walk, immediately after the walk, 15. min post-walk, and 30. min post-walk. Measures of physical exertion during walking were also obtained from cardiorespiratory parameters, time-distance parameters, and subjective scales. Variables on postural stability and on physical exertion were analyzed using two-way repeated measures ANOVA and Generalized Estimating Equations. Results: Physical exertion measures significantly increased when the duration of walk was increased from 6. min to 18. min in both control and hemiparetic participants. For postural stability measures, increasing the duration of walking led to a significant increase of postural sway in double-legged stance and sit-to-stand for the hemiparetic participants only. This effect on balance of hemiparetic participants was observed immediately after the end of the walk. Conclusion: This study demonstrated that physical exertion can increase postural sway in hemiparetic participants which could possibly lead to an increased risk of falling in these individuals. © 2011 Elsevier B.V.

Objectives: The aim of this study was to investigate the concurrent validity of the Smart Balance Master (SBM) tests in individuals with incomplete spinal cord injury. Design: Correlational study. Subjects: A total of 32 individuals with an American Spinal Injury Association Impairment Scale D spinal cord injury able to walk 10 m independently, with or without walking assistive devices. Methods: Outcome measures obtained from static and dynamic balance tests while standing using the SBM were compared to data obtained from the Berg Balance Scale (BBS) (14 items). Results: No difference in performance between paraplegic and tetraplegic subjects was noted in the SBM tests. No ceiling effect was apparent in the SBM tests. The highest levels of association with the BBS was found for the limits of stability test (-0.416 < R <-0.752, p = 0.05). The limits of stability test also correlated significantly with the majority of the other SBM tests and, except for the weight-shifting test, was completed by all but two participants. Conclusion: The limits of stability test of the SBM system appears to be useful for assessing dynamic standing-balance ability in spinal cord injury subjects and could potentially be used to complement the BBS. © 2013 The Authors.

The objective of this study was to examine the relationships between executive functions, physical fitness and mobility in well-functioning older adults. Forty-eight well functioning older adults (70.5 ± 5.3. years old; 20 men, 28 women) were included in this study. Two median splits were conducted based on each individual's performance for the 10MWT and TUG. Comparisons between groups of slower and faster individuals were made with regard to executive functions and physical fitness parameters. A correlational approach was used to assess the association between variables. Between groups comparisons revealed that faster individuals in mobility tests demonstrate better performances in measures of cognitive flexibility (0.68

The professions of physiotherapist in Quebec and "masso-kinésithérapeute" in France were both created in the same historical context, but evolved distinctly. In Quebec, entry-level training in university, post-graduate training of teacher-researchers and the development of research in rehabilitation science have been fundamental elements in the development of evidence-based practice. Could this be a source of inspiration for French colleagues? © 2015 Elsevier Masson SAS. All rights reserved.

Context: Trunk control is essential to engage in activities of daily living. Measuring trunk strength and function in persons with spinal cord injury (SCI) is difficult. Trunk function has not been studied in non-traumatic SCI (NTSCI). Objectives: To characterize changes in trunk strength and seated functional reach in individuals with NTSCI during inpatient rehabilitation. To determine if trunk strength and seated reach differ between walkers and wheelchair users. To explore relationships between trunk and hip strength and seated functional reach. Design: Observational study. Setting: Two SCI rehabilitation facilities. Participants: 32 subacute inpatients (mean age 48.0 ± 15.4 years). Outcome measures: Isometric strength of trunk and hip and function (Multidirectional Reach Test: MDRT) were assessed at admission and within 2 weeks of discharge. Analysis of variance was conducted for admission measures (MDRT, hip and trunk strength) between walkers and wheelchair users. Changes in MDRT, hip and trunk strength were evaluated using parametric and non-parametric statistics. The level of association between changes in values of MRDT and strength was also examined. Results: Significant differences between walkers and wheelchair users were found for strength measures (P < 0.05) but not for MDRT. Left- and right-sided reaches increased in wheelchair users only (P < 0.05). Associations between changes in hip strength, trunk strength, and reach distance were found (R = 0.67- 0.73). Conclusion: In clinical settings, it is feasible and relevant to assess trunk, hip strength, and MRDT. Future studies require strategies to increase the number of participants assessed, in order to inform clinicians about relevant rehabilitation interventions. © The Academy of Spinal Cord Injury Professionals Inc. 2014.
