Update: The Purnell Theory and Model for Culturally Competent Health Care.

The Purnell model and theory were created in 1998 and received input for clarity and parsimonious assumptions from several faculty at the University of Delaware. Initially, they were used in education and clinical practice settings to develop them further and to determine their usefulness in those settings. Since that time, changes have been made with additional assumptions, variant characteristics of culture, and an extensive assessment guide that can be used by all health professionals.

Different Error Size During Locomotor Adaptation Affects Transfer to Overground Walking Poststroke.

Background: Studies in neurologically intact subjects suggest that the gradual presentation of small perturbations (errors) during learning results in better transfer of a newly learned walking pattern to overground walking. Whether the same result would be true after stroke is not known.

Objective: To determine whether introducing gradual perturbations, during locomotor learning using a split-belt treadmill influences learning the novel walking pattern or transfer to overground walking poststroke.

Receptive Vocabulary Development of Children Placed in Foster Care and Children Who Remained With Birth Parents After Involvement With Child Protective Services.

Children who experience maltreatment are more likely than nonmaltreated children to demonstrate deficits in early receptive language skills that negatively impact their later academic achievement, social competence, and behavioral adjustment. It remains unclear whether placement in foster care affects children's early receptive language skills. In the current study, we examined whether children with Child Protective Services (CPS) involvement who were in foster care ( n = 176) had more advanced receptive vocabulary than children with CPS involvement who resided with their birth parents ( n = 144).

Prevalence of overweight and obesity among US youth with autism spectrum disorder.

The purpose of this study was to examine current overweight and obesity prevalence rates among US youth (aged 10-17 years) with and without autism spectrum disorder, based on the 2016 National Survey of Children's Health. Analyses of weight status, derived from parent-reported height and weight measures, were conducted for a weighted sample of 875,963 youth with autism spectrum disorder and 31,913,657 typically developing youth. Controlling for age, race/ethnicity, income, and sex, youth with autism spectrum disorder had significantly higher odds of overweight (odds ratio = 1.

Young Mothers' and Fathers' Perceptions of Relationship Violence: A Focus Group Study.

Teens and young adults who are pregnant or parenting are important targets for efforts to prevent intimate partner violence (IPV). To intervene appropriately and effectively, we need to fully understand the unique issues and contexts for IPV in this population. This focus group study examined young parents' ( N = 28) perceptions of their relationships, stressors and sources of conflict, forms of IPV, and help-seeking behaviors.

A Comprehensive Method to Measure 3-Dimensional Bra Motion During Physical Activity.

Breast and bra motion research aims to understand how the breasts/bra move to aid development of apparel that minimizes motion. Most previously published research has tracked nipple motion to represent bra motion. However, this method does not provide information regarding regional tissue motion.

Differences in praxis performance and receptive language during fingerspelling between deaf children with and without autism spectrum disorder.

Children with autism spectrum disorder present with a variety of social communication deficits such as atypicalities in social gaze and verbal and non-verbal communication delays as well as perceptuo-motor deficits like motor incoordination and dyspraxia. In this study, we had the unique opportunity to study praxis performance in deaf children with and without autism spectrum disorder in a fingerspelling context using American Sign Language. A total of 11 deaf children with autism spectrum disorder and 11 typically developing deaf children aged between 5 and 14 years completed a fingerspelling task.

The Effects of Walking Workstations on Biomechanical Performance.

Prolonged sitting has been associated with negative health effects. Walking workstations have become increasingly popular in the workplace. There is a lack of research on the biomechanical effect of walking workstations.

The Effect of 1 Week of a Multi-ingredient Dietary Preworkout Supplement on Resting and Postacute Resistance Exercise Vascular Function.

Dietary preworkout supplements are popular among recreational exercisers and athletes. However, the effects of these supplements on the vasculature, both at rest and during exercise, are not well studied. Therefore, the purpose of this study was to determine the effect of 1 week of supplementation with a multi-ingredient dietary preworkout supplement on measures of vascular function at rest and immediately following acute resistance exercise in young, recreationally active adults.

Achilles Tendon Resting Angle Relates to Tendon Length and Function.

Background: Following Achilles tendon rupture, tendon elongation leads to long term deficits in calf function. A surrogate measure of Achilles tendon length, Achilles tendon resting angle (ATRA), has been described but has not been validated against length measured using ultrasound. Therefore, the purpose of this study was to validate the ATRA against ultrasound.

Errors Associated With Utilizing Prescribed Scapular Kinematics to Estimate Unconstrained, Natural Upper Extremity Motion in Musculoskeletal Modeling.

Musculoskeletal modeling is capable of estimating physiological parameters that cannot be directly measured, however, the validity of the results must be assessed. Several models utilize a scapular rhythm to prescribe kinematics, yet it is unknown how well they replicate natural scapular motion. This study evaluated kinematic errors associated with a model that employs a scapular rhythm using 2 shoulder movements: abduction and forward reach.

The Importance of Inclusion for Cardiovascular Health Promotion Programs in Delaware.

Individuals with disabilities experience greater rates of cardiovascular disease than individuals without disabilities. This increase can be attributed to decreased levels of physical activity, poor eating habits, and increased levels of diabetes, smoking, and obesity. Individuals with disabilities are often excluded from surveillance, treatment, and prevention efforts.

Critical Issues in the Understanding of Young Elementary School Students at Risk for Problems in Written Expression: Introduction to the Special Series.

In this introduction to the special series "Critical Issues in the Understanding of Young Elementary School Students at Risk for Problems in Written Expression," we consider some of the contextual factors that have changed since a similar special issue was published in the Journal of Learning Disabilities in 2002. We also explore how the five articles included in this special series address the following important themes: early writing development, identification of students with writing difficulties, and effective interventions for struggling writers. In conclusion, we envision future directions to advance the field.

An Analysis of First-Grade Writing Profiles and Their Relationship to Compositional Quality.

To help all students meet the writing expectations of the Common Core State Standards, researchers need a deeper understanding of the characteristics of struggling writers. The purpose of this study was to explore the writing profiles of students including those who have or are at risk for writing disabilities. First-grade students ( N = 391) were assessed at the end of the school year using three writing assessments (spelling, sentence writing fluency, writing achievement).

The Advantages of Normalizing Electromyography to Ballistic Rather than Isometric or Isokinetic Tasks.

Isometric tasks have been a standard for electromyography (EMG) normalization stemming from anatomic and physiologic stability observed during contraction. Ballistic dynamic tasks have the benefit of eliciting maximum EMG signals for normalization, despite having the potential for greater signal variability. It is the purpose of this study to compare maximum voluntary isometric contraction (MVIC) to nonisometric tasks with increasing degrees of extrinsic variability, ie, joint range of motion, velocity, rate of contraction, etc.

Pairing Animal Cartoon Characters With Produce Stimulates Selection Among Child Zoo Visitors.

In order to address the pervasive trend of underconsumption of fruits and vegetables among children, we examined the hypothesis that children would be more likely to select fruits (apple slices, bananas, and oranges) and vegetables (baby carrots) when paired with animal cartoon image than when available without the character image. Tested in a randomized experiment using counterbalancing, products were arranged on two tables at two separate family fun nights held at a local zoo. Animal character produce parings were manipulated by placing one of two animals (tamarin or iguana) next to two of the four fruit or vegetable selections at each table, and by changing when available without the image.

Students With Chronic Conditions: Experiences and Challenges of Regular Education Teachers.

School nurses have observed the increasing prevalence of children with chronic conditions in the school setting; however, little is known about teacher experiences with these children in their regular classrooms. The purpose of this mixed-method study was to describe the experiences and challenges of regular education teachers when they have students with chronic conditions in their classroom and implications for the school nurse. The national sample consisted of regular education teachers.

Chinese Women's Experience of Intimate Partner Violence: Exploring Factors Affecting Various Types of IPV.

Using a sample of 553 married and divorced women in a large city in southern China, this study tested the effects of demographic characteristics, risk behaviors, patriarchal ideology, and personal mentality and skills on women's experience of physical violence, psychological violence, controlling behavior, and sexual abuse. Divorced women were more likely than married women to experience all types of IPV. Risk behaviors were consistently related to IPV incidents, whereas the impact of patriarchal ideology and personal mentality and skills was equivocal.

Self-Reported Symptoms of Parkinson's Disease by Sex and Disease Duration.

Parkinson's disease (PD) is a neurodegenerative disease with a wide range of symptom presentations. The purpose of this research was to compare self-reported motor and non-motor symptoms of PD by sex and disease duration. This study was a cross-sectional descriptive survey in community-dwelling people with PD.

Combined Ankle-Foot Energetics are Conserved When Distal Foot Energy Absorption is Minimized.

The large, late-stance energy generated by the ankle is believed to be critical during gait. However, the distal foot absorbs/dissipates a considerable amount of energy during the same phase. Thus, the energy generated by the combined ankle-foot system is more modest, which raises questions regarding the necessity of such a large ankle power and the interplay between foot and ankle energetics.

Calling the Shots: How Family Courts Address the Firearms Ban in Protection Orders.

Access to firearms increases the risk of a batterer killing his partner. Moreover, firearms may be more common in homes where intimate partner abuse has occurred. The Violence Against Women Act of 1994 banned possession of firearms by individuals subject to civil protection orders.

Nursing Research in Parkinson's Disease From 2006 to 2015.

Most people with Parkinson's disease (PD) reside in their homes with their family members. Nurses are in a good position to partner with people with PD and their family members for better self-management of the disease and improved quality of life. The purpose of this systematic review was to assess the state of the science of nursing research related to PD during the 10-year period, 2006 to 2015.

Effects of Unilateral Muscle Fatigue on Performance and Force Coordination in Bimanual Manipulation Tasks.

We examined the effects of unilateral muscle fatigue on the performance and coordination of grip (GF; normal component acting between the hand and object) and load force (LF; tangential component) in bimanual manipulation tasks, as well as the associated lateral differences. Eleven participants performed various symmetric bimanual tasks either without fatigue, or after fatiguing the GF producing muscles of either the nondominant or dominant hand. The GF/LF ratio of the fatigued and nonfatigued hand decreased and increased, respectively, while the neither the effects of fatigue on the task performance and GF-LF coordination, nor the lateral differences were revealed.
