Background: Physical inactivity and obesity are major public health issues. Recent studies have provided evidence that attributes of the built environment influence physical activity among adults and that factors such as greater urban sprawl are related to overweight and obesity. Few studies have developed objective individual-level measures of the built environment, a geographic scale that may be more relevant to certain types of physical activity, such as walking. In addition, further research is needed to assess the associations of both objective and perceived environmental factors with physical activity. In this 2-year exploratory study funded by the National Cancer Institute, we …

Dartmouth Scholarship

Environments conducive to walking may help people avoid sedentary lifestyles and associated diseases. Recent studies developed walkability models combining several built environment characteristics to optimally predict walking. Developing and testing such models with the same data could lead to overestimating one's ability to predict walking in an independent sample of the population. More accurate estimates of model fit can be obtained by splitting a single study population into training and validation sets (holdout approach) or through developing and evaluating models in different populations. We used these two approaches to test whether built environment characteristics near the home predict walking for …

Physical Therapy Scholarly Projects

Purpose: The purpose of this study is to analyze the amount of muscle activity of the rectus abdominis and external obliques during the gait cycle with the use of forearm crutches and three different weight bearing statuses. Subjects: Seven female adults were recruited from the University of North Dakota Physical Therapy program. Inclusion criteria: between the ages of 19 and 40 years of age, current physical therapy students, and healthy with no current upper or lower extremity injuries.

Instrumentation: The EMG data was collected by the Noraxon Telemyo 900 telemetry unit and analyzed using the MyoResearch XP software. Six Vicon …

Background and Purpose - Stroke survivors are commonly dependent in activities of daily living; however, the relation between prestroke mobility impairment and poststroke outcomes is poorly understood. The primary objective of this study was to evaluate the association between prestroke mobility impairment and 4 poststroke outcomes. The secondary objective was to evaluate the association between prestroke mobility impairment and a plan for physical therapy.

Methods - This was a secondary analysis of the National Stroke Project data, a retrospective cohort of Medicare beneficiaries who were hospitalized with an acute ischemic stroke (1998 to 2001). Logistic-regression modeling was used to examine …
