Attention focus and balance control in young and older adults

This thesis investigated attention focus and balance control in eighteen healthy young adults and eighteen healthy older adults. All participants performed sixteen consecutive trials of a balance task which involved standing for 30-s on an unstable platform that could rotate only in the roll direction. There were no attention focus instructions provided on any of the sixteen trials. Following the completion of the initial and final attempt in the series, participants reported "where" their attention had been focused when performing the task. The results showed differences in balance between young and older adults and improvements in balance with practice in both young and older adults. However, there were no differences in attention focus strategies between young and older adults. Both age groups directed attention to multiple sources during the balance task. An equal focus on internal (i.e., feet, trunk, and other body parts) and external (i.e., the platform) sources with little focus on events not related to the task dominated on the first attempt of the balance task. Focus on internal sources was maintained and focus on events not related to the task increased at the expense of focus on external sources on the final attempt of the balance task. Following the series of sixteen trials to establish "natural" attention focus, participants performed three randomly presented trials, each with specific attention focus instructions (i.e., think about minimizing movements of the feet, the trunk, or the platform). The results showed that, in contrast to the literature, instructions to focus on an internal source, the trunk, actually augmented control of the task as reflected in reduced trunk sway whereas instructions to focus on an internal source, the feet, or an external source, the platform, did not benefit performance on the task. Thus, the distance fi-om the interaction point of the body with the external source is critical and may not depend on whether the source is internal or external. Thus, a global attention focus instruction may not be beneficial and the nature of the task should be considered when adopting attention focus instructions for young and older adults.

Niagara Lodges of the Loyal Orange Association of British America

The Loyal Orange Association of British America is a Protestant fraternal society. The Loyal Orange Association originated in Ulster, Ireland during the late eighteenth century. Its purpose was to promote Protestant rights and privileges. The association was exclusively Protestant, fraternal, democratic, and benevolent. Orange principles were brought to Upper Canada by Protestant Irish settlers after 1815. The first Canadian Orange Lodge was formally established in Brockville, Leeds County, 1830. By the late 19th and early 20th century, the Loyal Orange Association of British North America had gained considerable popularity and political influence. Many prominent politicians, including several prime ministers, were members. Orangemen were particularly concerned with issues such as separate school funding, language rights, immigration, religious freedom and conscription. Further, they demanded the execution of Louis Riel and opposed the Jesuits Estates settlement. Administrative sketch courtesy Archives of Ontario.

Effects of Instruction on Walking and Turning Performance in Individuals with Parkinson's Disease

Parkinson’s disease (PD) is characterized by postural instability and gait impairment. Verbal instructions can reduce postural sway and improve gait performance in PD. For gait, this evidence is limited to unobstructed straight-path walking. As falls in PD often occur when turning, the purpose of this thesis was to determine if instructions can benefit turning performance in this population. Twelve individuals with PD performed two walking tasks (normal walking, walking with a 180 degree turn) under four instruction conditions (no instruction, take big steps, make larger trunk movements, focus on end and/or turn point). Task duration and trunk yaw and roll sway were calculated. In general, the results demonstrated that the instruction to take big steps improved performance for both tasks compared to providing no instruction or externally based instruction. These results suggest that instructions related to step amplitude may facilitate walking and turning performance in PD.
