Balance disorders impact millions of people causing substantial impact on quality of life due to psychological and physical hardships associated with poor balance. However, a clinically relevant, low cost, self-service system in detecting such disorders does not exist. Previous research has shown the built in accelerometer and gyroscope sensors of a smart phone to be valid tools in detecting standing balance performance using traditional linear analysis, however, such a system has yet to be proven useful in detecting dynamic postural variability. Indeed, more quantitative methods than are typically used in clinical settings are necessary for early detection of poor postural …

Validation Of Postural Sway Measurements Using Wii Balance Board, Zachary Meade
UNO Student Research and Creative Activity Fair
Standing balance measurements, such as postural sway, are vital for determining functional ability, risk of falling and recovery of injuries. Often the need to collect data outside of the typical clinical or research setting arises. However, obtaining these measurements outside of a laboratory setting can be very difficult, as the mobility of a laboratory-grade force plate (FP) is minimal, and its cost can be upwards of $20,000. The purpose of this study is to create a cheaper alternative by validating the Wii Balance Board’s (WBB; Nintendo, Redmond, Washington, USA) ability to measure postural sway patterns. The WBB can be acquired …

The general relationship between mobility/gait patterns and health conditions, has been established by many research studies. Gait patterns have been used in predicting fall incidents, assessing the movement of people with Parkinson disease and assessing gait characteristics of patients with major depression. However, not much has been reported in terms of how to utilize mobility data along with gait patterns to assess health levels and to identify early stages of certain diseases or conditions that impact mobility/gait patterns. In this project, we propose to develop a population analysis system based on recent Big Data technologies that relies on different types …

UAV’s are currently used extensively in outdoor environments for various applications, including wildfire monitoring, and agricultural surveying, their use in indoor applications have been fairly restricted, owing mainly to the difficulty to maneuver them in smaller indoor spaces and the inability to use GPS-based navigation system. Nevertheless, there are many indoor applications where UAVs could provide a safe, reliable and resilient means to perform operations that are dangerous for humans such as surveillance inside chemical plants, inventory scanning in cold storages etc., Autonomous UAV navigation in an indoor environment can be achieved by finding a collision-free flight path to pass …

In decision making processes, particularly when it comes to health-related decisions, each relevant piece of information is important. This is particularly important when it comes to health conditions for which there remains a high degree of non-determinism as far as diagnosis and treatment. Online social media, are places in which people feel free to share their opinions about numerous topics, including public health issues and how individuals have responded to different types of treatments associated with diseases. social media could represent a secondary source that can be used as a supplement to other data sources. This would allow individuals as …
Peak Vertical Ground Reaction Force & Stance Phase Time To Assess Post-Tka Interlimb Asymmetry, Abderrahman Ouattas
Peak Vertical Ground Reaction Force & Stance Phase Time To Assess Post-Tka Interlimb Asymmetry, Abderrahman Ouattas

In the US, more than 500,000 TKA surgeries are performed annually, to which 97% of those are led by OA1. Although knee pain is diminished post-TKA, unilateral efficiency and walking asymmetry is still unresolved several years after the surgery2. In fact, within a minimum of 10 years after the primary TKA, almost 50% of patients undergo a secondary TKA on the contralateral limb due to OA progression3. The purpose of this study was to determine if post-Total Knee Arthroplasty peak vertical ground reaction force (pVGRF) asymmetry could be identified using stance phase time differences …

After anterior cruciate ligament (ACL) rupture most will undergo reconstructive surgery. Within the first year after surgery 25% of patients will re-tear their ACL. Most of those injured attempt to return to sports which include running and cutting. The ability to produce appropriate ground reaction forces may be crucial for the successful return to sports without re-injury. Understanding stability of multidirectional ground reaction force (mGRF) production in healthy and ACL reconstructed (ACL-r) patients can lend insight to the high instance of re-injury. Typically, stability has been measured using linear analyses, but these analyses cannot capture the subtle time varying changes …
The Effects Of Walking Speed On Gait Propulsion When Wearing An Ankle-Foot Orthosis, Alli Kalina
The Effects Of Walking Speed On Gait Propulsion When Wearing An Ankle-Foot Orthosis, Alli Kalina
UNO Student Research and Creative Activity Fair
Peripheral artery disease (PAD) is a cardiovascular disease that results from blockage of one or more arteries in the lower extremity. Often, patients with PAD have reduced ability to push off with the foot at the end of the gait cycle. When walking, the ankle contributes the majority of the power to propel the body into the next step. An ankle-foot orthosis (AFO) is a device that aids in ankle propulsion by increasing the energy return, thus decreasing the ankle deficit in pathological individuals. The purpose is to investigate the effect of walking speed on ankle propulsion during walking. Subjects …
