Development of biomechanical measures to assist in the prediction of early progression in idiopathic scoliosis
Analyse biomécanique des pieds SACH et Seattle-Light durant la locomotion chez les personnes âgées amputées du membre inférieur
In North America and Europe, the elderly represent the largest percentage of individuals with a below the knee amputation. The purpose of this thesis was to compare two types of prosthetic feet, the Solid Ankle Cushion Heel (SACH) foot and the Seattle Light (SEAT-L) foot in a group of elderly unilateral below knee amputees (EBKA) during walking at a natural cadence. Ten EBKA aged 70.4 « 9.5 years and 18 healthy elderly (HE) subjects aged 70.8 « 7.0 years participated in this study; selection criteria required that the EBKA demonstrate sufficient locomotor potential in order to benefit from the SEAT-L foot's energy return capability. The EBKA underwent an initial gait evaluation with the SACH foot, this was followed by an eight session gait retraining program specific to the SEAT-L foot. Upon completion of the gait program, the EBKA underwent a final gait evaluation with the SEAT-L foot. In order to serve as a reference group, the 18 HE subject's gait was also evaluated once."--Résumé abrégé par UMI

Impacts of motion-based technology on balance, movement confidence, and cognitive function among people With dementia or mild cognitive impairment: protocol for a quasi-experimental pre- and posttest study
Background: While exercise can benefit the health and well-being of people with dementia or mild cognitive impairment, many exercise programs offered to this population are passive, unengaging, and inaccessible, resulting in poor adherence. Motion-based technologies are increasingly being explored to encourage exercise participation among people with dementia or mild cognitive impairment. However, the impacts of using motion-based technologies with people with dementia or mild cognitive impairment on variables including balance, movement confidence, and cognitive function have yet to be determined.
Objective: The purpose of this study is to examine the impacts of a group motion-based technology intervention on balance, movement confidence, and cognitive function among people with dementia or mild cognitive impairment.
Methods: In this quasi-experimental pre- and posttest design, we will recruit 24 people with dementia or mild cognitive impairment from 4 adult day programs and invite them to play Xbox Kinect bowling in a group setting, twice weekly for 10 weeks. We will require participants to speak and understand English, be without visual impairment, and be able to stand and walk. At pretest, participants will complete the Mini-Balance Evaluation Systems Test (Mini-BESTest) and the Montreal Cognitive Assessment (MoCA). We will video record participants during weeks 1, 5, and 10 of the intervention to capture behavioral indicators of movement confidence (eg, fluency of motion) through coding. At posttest, the Mini-BESTest and MoCA will be repeated. We will analyze quantitative data collected through the Mini-BESTest and the MoCA using an intent-to-treat analysis, with study site and number of intervention sessions attended as covariates. To analyze the videos, we will extract count and percentage data from the coded recordings.
Results: This study will address the question of whether a group motion-based technology intervention, delivered in an adult day program context, has the potential to impact balance, movement confidence, and cognitive function among people with dementia or mild cognitive impairment. The project was funded in 2019 and enrollment was completed on February 28, 2020. Data analysis is underway and the first results are expected to be submitted for publication in 2021.
Conclusions: This study will assess the feasibility and potential benefits of using motion-based technology to deliver exercise interventions to people with dementia or mild cognitive impairment. This work can also be used as the basis for developing specific software and future exercise programs using motion-based technology for people with dementia or mild cognitive impairment, as well as understanding some of the conditions in which these programs can be delivered
Ambulatory monitoring of activity levels of individuals in the sub-acute stage following stroke: a case series
<p>Abstract</p> <p>Background</p> <p>There is an important need to better understand the activities of individual patients with stroke outside of structured therapy since this activity is likely to have a profound influence on recovery. A case-study approach was used to examine the activity levels and associated physiological load of patients with stroke throughout a day.</p> <p>Methods</p> <p>Activities and physiologic measures were recorded during a continuous 8 hour period from 4 individuals in the sub-acute stage following stroke (ranging from 49 to 80 years old; 4 to 8 weeks post-stroke) in an in-patient rehabilitation hospital.</p> <p>Results</p> <p>Both heart rate (p = 0.0207) and ventilation rate (p < 0.0001) increased as intensity of activity increased. Results revealed individual differences in physiological response to daily activities, and large ranges in physiological response measures during 'moderately' and 'highly' therapeutic activities.</p> <p>Conclusion</p> <p>Activity levels of individuals with stroke during the day were generally low, though task-related changes in physiologic measures were observed. Large variability in the physiological response to even the activities deemed to be greatest intensity suggests that inclusion of such extended measurement of physiologic measures may improve understanding of physiological profile that could guide elements of the physical therapy prescription.</p
