Classifying Toe Walking Gait Patterns Among Children Diagnosed With Idiopathic Toe Walking Using Wearable Sensors And Machine Learning Algorithms, Rahul Soangra, Yuxin Wen, Hualin Yang, Marybeth Grant-Beuttler

Physical Therapy Faculty Articles and Research

Idiopathic toe walking (ITW) is a gait abnormality in which children’s toes touch at initial contact and demonstrate limited or no heel contact throughout the gait cycle. Toe walking results in poor balance, increased risk of falling, and developmental delays among children. Identifying toe walking steps during walking can facilitate targeted intervention among children diagnosed with ITW. With recent advances in wearable sensing, communication technologies, and machine learning, new avenues of managing toe walking behavior among children are feasible. In this study, we investigate the capabilities of Machine Learning (ML) algorithms in identifying initial foot contact (heel strike versus toe …

Mobile Phone Sensors Can Discern Medication-Related Gait Quality Changes In Parkinson's Patients In The Home Environment, Albert Pierce, Niklas König Ignasiak, Wilford K. Eiteman-Pang, Cyril Rakovski, Vincent Berardi

Psychology Faculty Articles and Research

Patients with Parkinson's Disease (PD) experience daytime symptom fluctuations, which result in small amplitude, slow and unstable walking during times when medication attenuates. The ability to identify dysfunctional gait patterns throughout the day from raw mobile phone acceleration and gyroscope signals would allow the development of applications to provide real-time interventions to facilitate walking performance by, for example, providing external rhythmic cues. Patients (n = 20, mean Hoehn and Yahr: 2.25) had their ambulatory data recorded and were directly observed twice during one day: once after medication abstention, (OFF) and once approximately 30 min after intake of their medication …

Cognitive-Motor Interactions In Gait And Postural Control And Cortical Network Neurocorrelates, Nathan Morelli

Theses and Dissertations--Rehabilitation Sciences

The ability to mitigate performance decrements during the concurrent completion of cognitive and motor tasks (i.e., dual task (DT)) deteriorates in patients with mild Traumatic Brain Injury (mTBI). It is theorized that the long-term sequelae of mTBI are due to the return to full activity prior to neurophysiologic healing. To mitigate the negative outcomes associated with mTBIs, translational clinical research of neurophysiologic recovery is of paramount importance for both athletic and non-athletic populations. Despite the well-known health consequences, clinical decisions regarding neurophysiologic recovery and return to activity remain problematic for clinicians. Return to activity decisions are currently based on normalization …

METHODS: Bilateral hip and knee flexion patterns (LH, RH, LK, and RK) of twenty-two healthy participants (12 adults and 10 pediatric) between the ages of 8 – 35 years were investigated. Participants …

Effects Of Visual Referencing On Backward And Forward Treadmill Walking In Vr Environments, Rahul Soangra, Sivakumar Rajagopal

Physical Therapy Faculty Articles and Research

Backward walking is used increasingly as a rehabilitation exercise for stroke and diabetic peripheral neuropathy patients to improve strength and balance. However, it is unclear how visual referencing affects backward and forward walking. In this study, we evaluated spatiotemporal gait characteristics changes due to visual referencing while backward/forward walking. Sixteen healthy young participants were recruited in this study. All participants walked for 2 min with and without visual referencing in the virtual reality environment. While walking backward participants faced the virtual reality screen similar to forward walking, but their treadmill belt direction of movement was reversed. All participants walked at …

Mediolateral Damping Of An Overhead Body Weight Support System Assists Stability During Treadmill Walking, M. Bannwart, S. L. Bayer, Niklas König Ignasiak, M. Bolliger, G. Rauter, C. A. Easthope

Physical Therapy Faculty Articles and Research

Background

Body weight support systems with three or more degrees of freedom (3-DoF) are permissive and safe environments that provide unloading and allow unrestricted movement in any direction. This enables training of walking and balance control at an early stage in rehabilitation. Transparent systems generate a support force vector that is near vertical at all positions in the workspace to only minimally interfere with natural movement patterns. Patients with impaired balance, however, may benefit from additional mediolateral support that can be adjusted according to their capacity. An elegant solution for providing balance support might be by rendering viscous damping along …

Features Of Acceleration And Angular Velocity Using Thigh Imus During Walking In Water, Koichi Kaneda, Yuji Ohgi, Mark Mckean, Brendan Burkett

International Journal of Aquatic Research and Education

Ten participants were assessed while walking in water and on land with wearable inertial measurement units (IMUs) attached to the right thigh. Longitudinal acceleration, anterior-posterior acceleration, and frontal axis angular velocity were measured at 100 Hz, matched with video analysis sampled at 25 Hz during the walking trials. The longitudinal acceleration showed almost 1 g from initial heel contact to 70% of one cycle, and the anterior-posterior acceleration showed a sinusoidal pattern, synchronizing the approximate posture of the thigh in water. The frontal axis angular velocity fluctuated less while walking in water compared with on land, because thigh motion speed …

Efficacy Of Rhythmic Acquisition On Gait Performance Among Individuals With Parkinson’S Disease, Demian L. Kogutek

Electronic Thesis and Dissertation Repository

The purpose of this study was to identify the ability of individuals with Parkinson’s disease (PD) to acquire different rhythmic complexity levels through individual home-based Improvised Active Music Therapy (IAMT) sessions. The study aimed to identify whether higher acquisition of rhythmic complexity levels improved gait performance, as well as beat perception and production abilities. In this single subject multiple baseline design, the study measured the ability of four right-handed participants with PD to acquire greater density of syncopation, as a measure of rhythmic complexity levels, while playing uninterrupted improvised music on a simplified electronic drum-set. An accredited music therapist led …

The Effect Of A Multiple Modality Mind-Motor Exercise Intervention On Single And Dual-Task Gait, Balance, And Executive Function, In Community Dwelling Older Adults With A Subjective Cognitive Complaint: A Randomized Controlled Trial., John P. Bocti

Electronic Thesis and Dissertation Repository

Cognitive decline disorders are becoming increasingly prevalent, with older adults at increased risk. Combined exercise has been recently explored as an intervention to help to prevent the decline, however cognitive activation in combination with physical activity has yet to be explored. Therefore, the purpose of the study is to determine the effects of multiple modality exercise programs in combination with a mind-motor task and their effects on mobility and cognitive variables. A total of (n=89) older adults (55+ yrs), with subjective cognitive complaints participated in a multiple modality exercise class, three days a week over six months, with the intervention …

The length of time the subjects were able to remain standing in a tandem stance and in a one-legged stance without becoming unbalanced was measured and recorded. The stride length of the subject’s second and third step from heel to heel was also …

Effect Of Dual Tasking On Walking Over Even And Uneven Surfaces In Functionally Independent Community Older Adults, Olajide L. Kolawole

Olajide L Kolawole

While several studies have reported a decrement in performance by older adults while walking and concurrently performing a dual task on even surfaces, to date the effects of dual tasking while walking on uneven surfaces commonly found in the community has received less attention. Thus, we sought to test the hypothesis that an incremental decrement in gait parameters will be observed, when walking on an uneven versus an even surface and furthermore, that this decrement would be dependent upon the concurrent performance of a secondary cognitive and/or motor task in functionally independent-living-community older adults. Dynamic Gait Index assessed the subject’s …

Identification Of Functional Parameters For The Classification Of Older Female Fallers And Prediction Of ‘First-Time’ Fallers, Niklas König Ignasiak

Physical Therapy Faculty Articles and Research

Falls remain a challenge for ageing societies. Strong evidence indicates that a previous fall is the strongest single screening indicator for a subsequent fall and the need for assessing fall risk without accounting for fall history is therefore imperative. Testing in three functional domains (using a total 92 measures) were completed in 84 older women (60–85 years of age), including muscular control, standing balance, and mean and variability of gait. Participants were retrospectively classified as fallers (n = 38) or non-fallers (n = 42) and additionally in a prospective manner to identify first-time fallers (FTFs) (n = 6) within a …

Classifying Lower Extremity Muscle Fatigue During Walking Using Machine Learning And Inertial Sensors, Jian Zhang, Thurmon Lockhart, Rahul Soangra

Physical Therapy Faculty Articles and Research

Fatigue in lower extremity musculature is associated with decline in postural stability, motor performance and alters normal walking patterns in human subjects. Automated recognition of lower extremity muscle fatigue condition may be advantageous in early detection of fall and injury risks. Supervised machine learning methods such as Support Vector Machines (SVM) have been previously used for classifying healthy and pathological gait patterns and also for separating old and young gait patterns. In this study we explore the classification potential of SVM in recognition of gait patterns utilizing an inertial measurement unit associated with lower extremity muscular fatigue. Both kinematic and …
