A new approach is proposed to identify gait events in non-laboratory environments with a single inertial measurement unit (IMU) embedded inside shoe. The aim of our work is to develop a useful clinical tool for monitoring individuals walking disability and detect specific pathological gait patterns. Temporal parameters of gait are determined by classification of accelerations and angular velocities. Wavelets denoising of IMU signals allows for an important amount of information that is exploited in different manners for event identification. It was found that wavelet denoising enhanced specific turning points which could effectively identify gait events. The method is verified by …

Lack of exercise has been linked to poor health issues (e.g., obesity) in American society. National (e.g., Appalachian Trail) and local trails are a potential resource for championing physical activity. To challenge sedentary lifestyle choices and promote more active ones, an understanding of the benefits perceived to be associated with physical and outdoor activities is needed. A total of 454 Appalachian Trail user surveys were collected. Validity analyses and reliability analyses showed the Benefits of Hiking Scale to be an accurate and consistent measure of the dimensions of recreation benefits. Within the improved condition dimension of Benefits, significant differences were …

Patients with end stage renal diseases (ESRD) on hemodialysis (HD) have high morbidity and mortality due to multiple causes, one of which is dramatically higher fall rates than the general population. The mobility mechanisms that contribute to falls in this population must be understood if adequate interventions for fall prevention are to be achieved. This study utilizes emerging noninvasive, portable gait, posture, strength, and stability assessment technologies to extract various mobility parameters that research has shown to be predictive of fall risk in the general population. As part of an ongoing human subjects study, mobility measures such as postural and …
