Treadmill Walking Capacity among Older Adults in Assisted Living Settings: A pilot, feasibility studyJohnson, Jenna January 2009 (has links)
Background: Decreased physical activity levels are an increasing concern, specifically for the
aging population. Older adults (>65 years) are able to achieve health benefits from participating
in a regular exercise program based on studies done in younger community-dwelling older
adults. However, there is less research investigating the efficacy of exercise for improving
physical function among the older adult population in assisted living settings. Barriers among the
research that has been done so far include generalizability, specificity and varying exercise
prescription details. The present study investigated the novel idea of using a treadmill with a
harness system, to engage older adults in aerobic exercise. It is unknown if it is feasible to recruit
and retain older adults in assisted living settings for such a treadmill study and if older adults
would be able to achieve intensities associated with health benefits.
Objectives: To determine the feasibility of recruitment and retention of older adults in an assisted
living facility for a pilot treadmill walking study. Secondary objectives include: to identify
determinants of participation and compliance with the treadmill study and to determine if the
older adult population in assisted living settings are able to achieve exercise intensities aligned
with established guidelines that are associated with health benefits.
Design and Setting: Pilot, multi-visit feasibility study in an Assisted Living Facility in the
Kitchener-Waterloo Region with care needs ranging from Retirement Home to Palliative Care
Population: Older adults (>65y) living in an assistive living facility who could follow two-step
commands and were able to walk two metres independently (with or without the use of an aid).
Methods: The feasibility of recruitment and retention was determined by recording: the number
of older adults who consented to participate in treadmill walking for three weeks; the number of
older adults (and/or their legal representatives) who declined treadmill participation and reasons
as to why; and the number of participants who completed the six treadmill sessions. Healthrelated
and demographic characteristics were collected to characterize the population while age,
number of co-morbidities, number of medications, cognition, fear of falling and walking ability
were evaluated as potential determinants of participation. A detailed attendance log was used to
assess compliance with the study. To determine if participants could achieve the recommended
exercise intensity associated with health benefits, exercise intensity (40 %HRR) and duration
(twenty minutes) achieved after the final treadmill session were reported.
Results: Thirty percent of the residents on the eligibility list were recruited and consented to
participate in the treadmill study. Average compliance was 94.4%±10.8%; one treadmill
participant dropped out due to declining health. There are no significant differences between
treadmill participants and those who chose not to walk on the treadmill. Treadmill participants
were able to achieve the recommended intensity (40%HRR) and achieved an average intensity of
50.3% ± 30.2% and a frequency of three sessions in one week. Average total duration was
approximately five minutes shy (14:53min ± 6:43min) of the recommendation of twenty
minutes.
Conclusion: The current study provides preliminary evidence that it is feasible to recruit and
retain older adults in assisted living facilities to participate in a three week treadmill walking
study, however it may be difficult to recruit a large number of individuals for a larger study.
Treadmill participants were able to achieve ACSM’s recommended intensity and frequency for
aerobic or endurance exercise. Secondly, the older adult population living in assisted settings
may be able to achieve the recommended exercise prescription targets for cardiovascular
training, specifically intensity and frequency; however they may need more than three weeks of
progression or multiple sessions per day to obtain the recommended duration.

The effect of noise on the dynamics of a 2-D walking modelCampbell, Bradley Cortez 27 February 2012 (has links)
Walking models have been used to explore concepts such as energy, step variability, control strategies and redundancy in walking. A 2-D dynamic walking model was used to determine the levels of variability in gait while being perturbed. The perturbations were added in the form of randomly added noise applied at different magnitudes. The model was comprised of two equal length legs and masses at the feet and hips. The model walked on a flat surface and each step was initialed by an impulse at the swing leg. The magnitude of the impulse determined the size of the model's steps. In this study, the walker took steps with lengths that were than were analogous to humans. An attempt to offset the effect of the noise was made by adding a proportional controller to correct the errors of the applied impulse. The control equation was comprised of gain, A, and noise, [xi], term. The step length, time and speed were calculated to analyze how the model walks. It was hypothesized that the model would use a strategy similar to humans on a treadmill and follow a goal equivalent manifold. The manifold was all possible solutions of step length and step time for maintaining constant speed. Any fluctuations in step length and time would still result in constant speed. The results showed that the model's gait became more variable as noise was added. When the control was added through the gain being increased, the model steps became more variable. The model did not follow the same control strategy as humans and coordinate steps along the GEM. As the model began taking longer step lengths the step time decreased. / text

The effect of walking on quality of life of elderly peopleLam, Chi-ting, 林之婷 January 2014 (has links)
Background: The world is facing an ageing population. Physical inactivity is considered as the fourth leading risk factor for non-communicable diseases. Walking is recognized as an affordable exercise to elderly people. However there is rarely any systematic review conducted to examine the effect of walking on quality of life of elderly people
Objective: This systematic review of randomized controlled trials is to examine the effect of walking on quality of life (QoL) of older people.
Methods: Articles were searched through Medline and Ovid by using keywords of “elderly people”, “aged, 50 or more”, “old people”, “elderly”, “the aged”, “walk”, “walking”, “QoL” and “quality of life”. PICO criteria were used for the criteria in selecting articles for this review. CONSORT 2010 checklist was used to assess the quality of included studies.
Results and Discussion: 8 articles out of 237 articles from Medline and 883 articles from Ovid were included in this systematic review after applying the inclusion and exclusion criteria. Studies were from 4 different countries. Average age of the subjects was above 60. Subjects were randomized to intervention (walking) and control groups. Outcome measures were QoL indicators. There was significant improvement in various QoL dimensions while other studies have results of either no significant difference between intervention and control groups, or results favoring the control group. Subjects’ adherence was high in the initial phase, yet it was doubtful whether subjects could maintain the habit without the assistance of experimenter and the assisting measures.
Conclusions: From this systematic review, the effect of walking on quality of life on elderly people is still unclear. More large scale research works, especially randomized controlled trials are needed to examine the effect of walking on elderly people. / published_or_final_version / Public Health / Master / Master of Public Health

Simulation and experimental analyses of human movement : application to post-stroke hemiparetic gaitPeterson, Carrie Lynn, 1981- 02 December 2010 (has links)
Stroke is the leading cause of long term disability with improved walking being an important goal following stroke. Understanding deficits that result in reduced walking performance by hemiparetic subjects is important for the design of effective rehabilitation strategies. The goal of this research was to investigate muscle coordination and mechanical work in hemiparetic walking and mechanisms of acceleration and deceleration in nondisabled walking as a framework for investigating non-steady state walking in hemiparetic subjects.
Musculoskeletal modeling and simulation analyses were used to compare individual muscle contributions to important walking subtasks and muscle mechanical work by representative hemiparetic subjects (limited community and community walkers) during pre-swing with a representative speed and age-matched control. Simulation analyses identified decreased paretic soleus and gastrocnemius contributions to forward propulsion and power generation as the primary impairment in the limited community walker compared to the control. Comparison of mechanical work showed that total paretic and non-paretic fiber work was increased in the limited community walker, which was primarily related to decreased fiber and tendon work by paretic soleus and gastrocnemius. The decreased output by the ankle plantar flexors required compensatory work by other muscles. Also, the experimental analyses of accelerated and decelerated walking showed that the ankle plantar flexor moment was positively related to braking and propulsive impulses, which increased with speed. Thus, deficits of the paretic plantar flexors limit forward propulsion and increase mechanical work during pre-swing, and would limit the ability of hemiparetic walkers to accelerate and decelerate, which are essential tasks in daily living activities.
For the community walker, simulation analyses showed that deficits in paretic swing initiation are a primary impairment. Specifically, the paretic gastrocnemius and hip flexors contributed less to swing initiation in the community walker compared to the control subject. Total paretic and non-paretic fiber work was increased in the community walker, primarily due to increased work by the hip abductors and adductors. Because step length and step frequency were positively related to walking speed in accelerated and decelerated walking, impaired paretic swing initiation would likely limit the community walker’s ability to accelerate and decelerate. / text

Relationship of personal factors and perceived built environmental factors to walking behaviour of community-dwelling middle-aged and older adultsChen, Yijie (Jennifer) 03 April 2013 (has links)
The purpose of this study was to investigate the relationship between personal factors and perceived built environmental factors and walking behaviour among middle-aged and older adults. The sample consisted of 647 people aged 45 years and above. Walking behaviour was assessed using pedometers. Decreased walking was significantly associated with increased age (r=-0.366, p<0.001). Education level (F=4.13, p=0.016) and self-rated health status (t=6.07, p<0.001) were positively associated with walking. When considering the effect of age, education level was no longer associated with walking. Better perception of general safety (F=3.105, p=0.005) and fewer safety concerns (F=7.531, p=0.001) were positively associated with walking. Age and self-rated health status jointly contributed to the walking behaviour (p<0.001), explaining 16.2% of the variance. These findings may suggest future neighbourhood interventions for age-friendly communities in Winnipeg, and help to accommodate changes through addressing perceived neighbourhood safety concerns and facilitating increased physical activity among middle-aged and older adults.
