Single Leg Hop Landing Analysis In Patients With Chronic Ankle Instability, Lateral Ankle Sprain Copers, And Healthy Individuals, Jordyn Ashlyn Rine

Theses and Dissertations

CONTEXT: There are an estimated 28,000 ankle injuries that occur per day in the United States, thus making the pathology one of the most common sports-related injuries. Lateral ankle sprains account for 80% of all athletic injuries and approximately 73% will suffer from a recurrent injury. The residual symptoms that linger following repetitive lateral ankle sprains are often correlated with chronic ankle instability (CAI). Lateral ankle sprain (LAS) copers successfully cope with the damage that results from sustaining a lateral ankle sprain, whereas CAI patients suffer from residual symptoms. Traditional measures of COP from force-plate data are useful in evaluating …

Child Maltreatment Disclosure To A Text Messaging-Based Crisis Service: Content Analysis, Laura Schwab-Reese, Nitya Kanuri, Scottye Cash

Purdue University Libraries Open Access Publishing Fund

Background: Disclosure is a difficult but important process for victims of child maltreatment. There is limited research on child maltreatment disclosure. Young people have been reluctant to disclose victimization to adults, but short message service (SMS) crisis services may represent one novel method of engaging young people around sensitive topics.

Objective: The purpose of this study was to determine characteristics of child maltreatment disclosure to an SMS-based crisis service.

Methods: We conducted a content analysis of all conversations (N=244) that resulted in a mandatory report by an SMS-based crisis service between October 2015 and July 2017. We coded characteristics of …

Motor Preparation For Compensatory Reach-To-Grasp Responses When Viewing A Wall-Mounted Safety Handle, David A.E. Bolton, David M. Cole, Jixun Zhan, Manhoud Mansour, Garrett Rydalch, Douglas W. Mcdannald, Sarah E. Schwartz

Kinesiology and Health Science Faculty Publications

The present study explored how motor cortical activity was influenced by visual perception of complex environments that either afforded or obstructed arm and leg reactions in young, healthy adults. Most importantly, we focused on compensatory balance reactions where the arms were required to regain stability following unexpected postural perturbation. Our first question was if motor cortical activity from the hand area automatically corresponds to the visual environment. Affordance-based priming of the motor system was assessed using single-pulse Transcranial Magnetic Stimulation (TMS) to determine if visual access to a wall-mounted support handle influenced corticospinal excitability. We evaluated if hand actions were …

High Intensity Functional Training (Hift) And Competitions: How Motives Differ By Length Of Participation, Allyson G. Box, Yuri Feito, Chris Brown, Katie M. Heinrich

Faculty Articles

High Intensity Functional Training (HIFT) is a unique fitness method that promotes an active lifestyle and has seen exponential and continual growth over the last two decades. Motivation to exercise is likely to change over time as individuals’ motives to initiate exercise may be different than those which motivate them to maintain an exercise program. The purpose of this study was to examine the motivational factors reported by individuals who actively engage in HIFT with varying length of participation and competition levels. 737 adults (32.4 ± 8.2 years) with more than three-months of HIFT experience completed an online version of …

The Role Of Interaction And Predictability In The Spontaneous Entrainment Of Movement., Dobromir Dotov, Valérie Cochen De Cock, Christian Geny, Petra Ihalainen, Bart Moens, Marc Leman, Benoît Brady, Simone Dalla Bella

Journal Articles

People walking side by side spontaneously synchronize their steps on some occasions but not on others, which poses a challenge to theories of perception-action based on interactive dynamic systems. How can action be spontaneously entrained by some sources of perceptual information while others are selectively ignored? The predictive processing framework suggests that saliency factors such as stimulus predictability, consistent deviation, and interactivity of the stimulus control the coupling between the motor system and perceptual information. To test this, we compared entrainment of gait cadence by two interactive auditory stimuli and two noninteractive but predictable, faster than preferred stimuli that were …

Staying Upright By Shutting Down? Evidence For Global Suppression Of The Motor System When Recovering Balance, Caleigh Goode, David M. Cole, David A.E. Bolton

Kinesiology and Health Science Faculty Publications

Background

When automatic, yet unwanted action is quickly inhibited, short-lived suppression throughout the motor system ensues. This effect is referred to as global suppression. Although response inhibition is essential for behavioral flexibility, widespread motor suppression may delay action reprogramming. In reactive balance control, even fleeting suppression of the motor system could interfere with our ability to adapt compensatory reactions quickly enough to avoid a fall.

Research Question

Is muscle activity in the hand suppressed when a prepotent compensatory step becomes suddenly blocked in a balance recovery task?

Methods

Nineteen young adults were tested using a lean and release apparatus. …

Meeting Point: Partner Dancing As Couple's Therapy, Rami Eckhaus

Expressive Therapies Dissertations

This dissertation research explored the experience of partner dancing as a therapeutic process that reflects upon the dynamics and interactions of couples who are in the process of couple's therapy. The research also aimed to gain insight on the ways in which the experience of partner dancing can support these couples' therapeutic processes. Partner dancing is a dance-form that is based on the interaction between two individuals. Such interaction requires the dancing couples to communicate on many levels that may uncover layers of their relational dynamics. In this research, five couples who were undergoing couple's therapy were asked to participate …
