Biomechanical Effects Of Obesity On Balance, Hannah Del Porto, Celia Pechak, Darla Smith, Rebecca Reed-Jones Oct 2012

Biomechanical Effects Of Obesity On Balance, Hannah Del Porto, Celia Pechak, Darla Smith, Rebecca Reed-Jones

International Journal of Exercise Science

International Journal of Exercise Science 5(4) : 301-320, 2012. The objective of this review was to analyze the current literature related to the effects of obesity on balance. These effects were observed during conditions of static balance, perturbed balance and dynamic balance during gait. The literature review included studies focused on the biomechanical effects of obesity, the relationship between weight loss and balance, and the relative efficacy of weight loss as a balance intervention. The older adult population, which faces increased risk of falls and related injuries, was highlighted where targeted research was available. The existing literature provides evidence for ...


Postural Control Strategy During Standing Is Altered In Patients With Multiple Sclerosis, Jessie M. Huisinga, Jenna M. Yentes, Mary Filipi, Nicholas Stergiou Aug 2012

Postural Control Strategy During Standing Is Altered In Patients With Multiple Sclerosis, Jessie M. Huisinga, Jenna M. Yentes, Mary Filipi, Nicholas Stergiou

Journal Articles

Disturbances in balance are one of the first reported symptoms of Multiple Sclerosis (MS), yet limited research has been performed to classify the postural control deficits in this population. This study investigated the variability present in the sway patterns during quiet standing in patients with MS (PwMS) and healthy controls. Subjects were assessed (eyes open, closed) standing on a force platform. Variability of the sway patterns was quantified using a measure of amount of variability (root mean square; RMS) and two measures of temporal structure of variability (Lyapunov Exponent – LyE; Approximate Entropy – ApEn). RMS results revealed significantly higher amount of ...


Taking Balance Measurement Out Of The Laboratory And Into The Home: Discriminatory Capability Of Novel Centre Of Pressure Measurement In Fallers And Non-Fallers, Denise Mcgrath, Emer P.

We investigated three methods for estimating centre of pressure excursions, as measured using a portable pressure sensor matrix, in order to deploy similar technology into the homes of older adults for longitudinal monitoring of postural control and falls risk. We explored the utility of these three methods as markers of falls risk in a cohort of 120 community dwelling older adults with and without a history of falls (65 fallers, 55 non-fallers). A number of standard quantitative balance parameters were derived using each centre of pressure estimation method. Rank sum tests were used to test for significant differences between fallers ...


Influence Of A Short-Term, Multicomponent Intervention On Balance And Strength Among The Elderly, Pamela C. Webert Jun 2012

Influence Of A Short-Term, Multicomponent Intervention On Balance And Strength Among The Elderly, Pamela C. Webert

Master's Theses and Doctoral Dissertations

Background: Few studies have combined strength and balance training to assess improvement of activities of daily living among subjects over the age of 65. The purpose of this study was to demonstrate how an eight-week balance and strength training program can lead to improvements in activities of daily living among elderly individuals.

Methods: The subjects consisted of 14 elderly women and 3 elderly men who were all residents of an independent living community. There were 10 subjects in the intervention group and 7 subjects in the control group. The intervention group participated in a supervised balance and strength training program ...


Correlation Between Cognitive Functions, Balance And Risk Of Fall In Elderly With Alzheimer’S Dementia, Salma S. Soleman Hernandez, Flavia Gomes De Melo Coelho, Sebastião Gobbi, Florindo Stella Mar 2012

Correlation Between Cognitive Functions, Balance And Risk Of Fall In Elderly With Alzheimer’S Dementia, Salma S. Soleman Hernandez, Flavia Gomes De Melo Coelho, Sebastião Gobbi, Florindo Stella

International Journal of Exercise Science: Conference Proceedings

The Alzheimer’s dementia (AD) represents a clinical condition inherent to many chronic and neurodegenerative diseases that are usually related to a decline in the cognitive and physical functions. The objective of this research was to verify the correlation between cognitive functions, balance and risk of fall in elderly with AD when submitted to a systemized physical activity program. The sample consisted of 16 elderly divided in two groups: the Intervention Group (IG) n=9 77.7±7.5 years and the Control Group (CG) n=7 84.4 ± 6.1 years. Both groups were submitted to the tests: Mini ...


Use Of A Video Game Based Balance Training Intervention On The Balance And Function Of Children With Developmental Disabilities, Gina C. Siconolfi-Morris Jan 2012

Use Of A Video Game Based Balance Training Intervention On The Balance And Function Of Children With Developmental Disabilities, Gina C. Siconolfi-Morris

Theses and Dissertations--Rehabilitation Sciences

Many children with developmental disabilities (DD) have physical impairments and limitations in their participation. Rehabilitation research often focuses on either physical impairments or participation restrictions, when both need to be investigated. The purposes of these two studies were to evaluate an at home therapist directed video game balance training intervention on balance, gait velocity (GV), hip strength and activities of children with DD. The pilot study was a single-subject non-concurrent multiple baseline design. Balance measures included: weight bearing symmetry; center of pressure area and velocity; time to boundary mean minima and standard deviation; and timed up and go. The participant ...


Impacts On Balance When Walking In Occupational Footwear, Harish Chander Jan 2012

Impacts On Balance When Walking In Occupational Footwear, Harish Chander

Electronic Theses and Dissertations

Hazards and challenges present in the workplace pose a number of potential risks for injuries and illness. Nearly 3.1 million nonfatal workplace injuries and illness were reported in 2010 (BLS, 2010). The probability of falls has been related to balance decrements. Further, an important point of distinction is 45% of all falls have been attributed to inappropriate footwear (Menant et al. 2008) Previous studies have shown decrements in balance as a result of different footwear (Menant et al. 2008) and after an increased workload over a specific period of time (Yaggie & McGregor, 2002; Gribble & Hertel, 2004). Occupational footwear is often designed for safety and may fail to provide appropriate foot biomechanics. As such the functionality of occupational footwear may impact balance characteristics over time. The purpose of the study is to examine the differences in balance in while wearing different types of occupational footwear for extended durations. Fourteen healthy male adults (aged 23.6±1.2 years; height of 181±5.3 cm; weight ...
