Concurrent Validity Of Accelerations Measured Using A Tri-Axial Inertial Measurement Unit While Walking On Firm, Compliant, And Uneven Surfaces, Michael H. Cole, Wolbert Van Den Hoorn, Justin K. Kavanagh, Steven Morrison, Paul W. Hodges, James E. Smeathers, Graham K. Kerr

Rehabilitation Sciences Faculty Publications

Although accelerometers are extensively used for assessing gait, limited research has evaluated the concurrent validity of these devices on less predictable walking surfaces or the comparability of different methods used for gravitational acceleration compensation. This study evaluated the concurrent validity of trunk accelerations derived from a tri-axial inertial measurement unit while walking on firm, compliant and uneven surfaces and contrasted two methods used to remove gravitational accelerations; i) subtraction of the best linear fit from the data (detrending); and ii) use of orientation information (quaternions) from the inertial measurement unit. Twelve older and twelve younger adults walked at their preferred …

Changes In The Dynamics Of Postural And Locomotor Control As A Result Of Varying Task Demands, Kathleen Sherry Thomas

Human Movement Studies & Special Education Theses & Dissertations

The aim of this study was to examine changes in postural and locomotor control under varying task demands. Three experiments were designed to address the impact that fast walking had on standing posture over time, slow walking had on gait dynamics over time, and the extent to which gait speed interacts with the ability to walk randomly.

For experiment I, the aim was to identify the time course in which postural adaptation occurred while walking at faster than preferred speeds. Postural motion was assessed at specific intervals over a 35-min walking trial. Findings revealed that walking at a faster speed …

The Effect Of Joint Mobilization On Functional Outcomes Associated With Chronic Ankle Instability, Matthew C. Hoch

University of Kentucky Doctoral Dissertations

Ankle sprains are among the most common injuries sustained by physically active individuals. Although ankle sprains are often considered innocuous in nature, a large percentage of individuals experience repetitive sprains, residual symptoms, and recurrent ankle instability following a single acute sprain; otherwise known as chronic ankle instability (CAI). In addition to repetitive ankle trauma, those with CAI experience reductions in functional capacity over the life span. This indicates that current intervention strategies for CAI are inadequate and require further investigation.

The objective of this dissertation was to explore differences in walking and running gait parameters between individuals with and without …

The Wilson Disease: A Casereport, Nai-Chiung Huang, Ta-Sen Wei, Yen-Chung Chen, Wei-Chen Liang, Peng-Ta Liu

Rehabilitation Practice and Science

Wilson disease is a rare autosomal recessive inherited disorder of copper metabolism. The genetic defect, localized to chromosome arm 13q, has been shown to affect the copper-transporting adenosine triphosphatase gene. The major pathology is excessive deposition of copper in the liver, brain, and other tissues. The most common presenting neurological features are tremor, dystonia and ataxia that influence the motor control and gait. The diagnosis is confirmed by measurement of serum ceruloplasmin, urinary copper excretion and hepatic copper content as well as the detection of Kayser-Fleischer rings.The subject in our case study is a 25-year-old, female patient with Wilson disease. …

BACKGROUND: Decline in physical functional ability is an intrinsic component of the dementia syndrome. Reductions in muscle mass and strength represent a major factor in the loss of functional ability Although resistance exercise has been studied as a method for maintaining/recovering function in populations of frail older adults, people with dementia have been systematically excluded because of uncertainty about the reliability of outcome measurements.

OBJECTIVE: The purpose of this study was to determine the test-retest reliability of a battery of established performance-based measures of strength and function among subjects with dementia.

SETTING: A hospital-affiliated adult day-care facility.

SUBJECTS: Twelve of …

The Use Of Neuromuscular Electrical Stimulation In The Gait Training Of Children With Cerebral Palsy: A Literature Review, Rachel Rolfson

Physical Therapy Scholarly Projects

Cerebral palsy is a common developmental disorder that causes a wide array of problems in the population. The manifestations of cerebral palsy commonly interfere with the child's activities of daily living, including the important function of gait. It is therefore important that physical therapists be knowledgeable about the various treatment options used in gait training of children with cerebral palsy, as well as their effectiveness.

Neurodevelopmental techniques (NDT), neurosurgical interventions, and orthotics are just a few of the numerous treatment options available for the gait training of children with cerebral palsy. Neuromuscular Electrical Stimulation (NMES) has recently become a popular …

Gait Analysis For The Enhancement Of Aka Gait Patterns, Krista Lausen

Physical Therapy Scholarly Projects

The amputation of a body part is both a physically and psychologically traumatic event for an individual. There are a number of gait deviations that often occur when a person has had a lower extremity amputation, especially when that amputation is above the knee. The entire locomotor mechanism of the body is altered by this change. The person must then adjust ahd relearn how to accommodate for the loss.

This literature review will discuss specific causes of certain gait deviations to determine whether the deviation is due to a musculoskeletal deficit or habit pattern on the part of the patient …

The Effects Of Supramalleolar Orthoses On The Biomechanics Of The Knee, Foot, And Ankle During Gait: A Single-Subject Design, Jennifer Ruth Stauffer

Physical Therapy Scholarly Projects

Gait deviations are a common problem associated with disorders of movement and posture such as cerebral palsy (CP). Inhibitive casts and ankle-foot orthoses have been used to treat gait deviations in children with CP, but they have not satisfied the needs of children who are able to achieve active dorsiflexion and plantarflexion but lack stability at the subtalar joint. Supramalleolar orthoses (SMOs) were developed to address that need. SMOs, along with physical therapy, have been used to treat children with CP, but little research has been conducted to determine the actual effects of the SMO on lower extremity biomechanics during …

The Effect Of Semi-Rigid Foot Orthotics On Subtalar Joint Subluxation And Pain During Three Gait Velocities, Lynnelle A. Gelinske

Physical Therapy Scholarly Projects

It has been established that foot orthotics can effectively control the amount of maximal calcaneal eversion while walking. However, there are conflicting studies about the successfulness of foot orthotics in regulating rearfoot motion during running. The purpose of this study was to determine the effectiveness of standard vertical semi-rigid foot orthotics in controlling subtalar joint subluxation (ST JS) and pain during three gait velocities. The study was also completed to ascertain whether any correlations existed between 8T JS and the static lower extremity measurements of tibio-fibular varum, gastrocnemius flexibility, and navicular drop. The results of this study revealed that pain …
