Characterization of bilateral reaching development using augmented reality games.

Bilateral coordination is commonly impaired in neurodevelopmental conditions including cerebral palsy, developmental coordination disorder, and autism spectrum disorder. However, we lack objective clinical assessments that can quantify bilateral coordination in a clinically feasible manner and determine age-based norms to identify impairments. The objective of this study was to use augmented reality and computer vision to characterize bilateral reaching abilities in typically developing children.

A cross-cultural investigation of active transportation and community participation: Results from the WHO survey of Global Ageing and Adult Health.

Little is known about how the associations between active transportation and community participation may vary across national contexts. Using representative datasets from China, Ghana, India, Mexico, Russia, and South Africa collected in the Study on Global Ageing and Adult Health (N = 33,535), we estimated multi-group confirmatory factor analyses, tests of measurement invariance, and predictive models. Standardized coefficients were equivalent across countries and showed a modest positive association between active transportation and community participation (the variance explained by active transportation ranged from 1.

A novel method to map community- and neighborhood-level access to rural physical activity built environments in the United States.

Physical activity (PA) built environments may support PA among rural youth and families. In the United States (U.S.

Randomized trial examining the effect of exercise and wellness interventions on preventing postpartum depression and perceived stress.

Background: Approximately 13-19% of postpartum women experience postpartum depression and a majority report at least some stress during the postpartum phase. Traditional interventions such as psychotherapy and antidepressant medications are often not feasible or desirable. The purpose of this study was to examine two low cost, brief, accessible interventions designed to prevent postpartum depression and perceived stress among women at high risk.

Investigating the neuroanatomy underlying proprioception using a stroke model.

Neuroanatomical investigations have associated cortical areas, beyond Primary Somatosensory Cortex (S1), with impaired proprioception. Cortical regions have included temporoparietal (TP) regions (supramarginal gyrus, superior temporal gyrus, Heschl's gyrus) and insula. Previous approaches have struggled to account for concurrent damage across multiple brain regions.

Effect of Wearable Technology-Based Physical Activity Interventions on Breast Cancer Survivors' Physiological, Cognitive, and Emotional Outcomes: A Systematic Review.

This systematic review synthesized all randomized controlled trials (RCTs) and controlled trials examining the effects of wearable health technology-based physical activity interventions on physiological, cognitive, and emotional outcomes in breast cancer survivors (BCS). We searched NCBI, Academic Search Premier, EMBASE, Web of Science, PubMed, and Medline from inception to March 2021. We included studies which: (1) were RCTs or controlled trials ≥8 weeks in duration; (2) were peer-reviewed and published in English; (3) sampled BCS in full remission and had not received treatment for at least six months; (4) utilized wearable health technology (e.

Community-based intervention effects on older adults' physical activity and falls: Protocol and rationale for a randomized optimization trial (Ready Steady3.0).

The Ready Steady 3.0 trial is designed to test the main and interactive effects of two behavior change intervention components, within an 8-week physical activity intervention, on older adults' physical activity (PA). Each component is comprised of behavior change strategies that emphasize two different evidence-based ways to motivate older adults to be active: interpersonal and intrapersonal.

Universal childhood obesity prevention in a rural community: Study design, methods and baseline participant characteristics of the NU-HOME randomized controlled trial.

Childhood obesity is a major health concern in the United States (US) and those living in rural communities are at higher risk than their urban counterparts. Few prevention trials have engaged whole families of school-age children in community settings, and none to date have promoted family meals, family activity and healthful home environments in rural settings through a rigorous, randomized controlled trial (RCT). The New Ulm at HOME (NU-HOME) study recruited 114 parent/child dyads in a two-arm (intervention versus wait-list control) RCT to test the efficacy of a family meals-focused program aimed to prevent excess weight gain among 7-10 year-old children in rural Minnesota.

Rationale, design, and baseline data for the Healthy Mom II Trial: A randomized trial examining the efficacy of exercise and wellness interventions for the prevention of postpartum depression.

Approximately 13-19% of women experience postpartum depression and approximately one-third of women who have a history of depression develop depression during the postpartum phase. Exercise is an efficacious intervention for depression among adults; however, few studies have examined the effect of exercise on postpartum depression. The purpose of this study was to conduct a randomized controlled trial examining the effect of exercise and wellness interventions on preventing postpartum depression among women at risk.

The effect of sleep pattern changes on postpartum depressive symptoms.

Background: Research indicates that poor sleep is associated with postpartum depression; however, little is known regarding this relationship among postpartum women who are at high for postpartum depression. This study examined the relationship between changes in self-reported sleep patterns (from six weeks to seven months postpartum) and depressive symptoms at seven months postpartum among women who were at high risk for postpartum depression.

Methods: Participants (n = 122) were postpartum women who were at an increased risk for postpartum depression (personal or maternal history of depression) and had participated in a randomized exercise intervention trial.

The Coupling of Peripheral Blood Pressure and Ventilatory Responses during Exercise in Young Adults with Cystic Fibrosis.

Purpose: Cystic fibrosis (CF) is commonly recognized as a pulmonary disease associated with reduced airway function. Another primary symptom of CF is low exercise capacity where ventilation and gas-exchange are exacerbated. However, an independent link between pathophysiology of the pulmonary system and abnormal ventilatory and gas-exchange responses during cardiopulmonary exercise testing (CPET) has not been established in CF.

Bone strength estimates relative to vertical ground reaction force discriminates women runners with stress fracture history.

Purpose: To determine differences in bone geometry, estimates of bone strength, muscle size and bone strength relative to load, in women runners with and without a history of stress fracture.

Methods: We recruited 32 competitive distance runners aged 18-35, with (SFX, n=16) or without (NSFX, n=16) a history of stress fracture for this case-control study. Peripheral quantitative computed tomography (pQCT) was used to assess volumetric bone mineral density (vBMD, mg/mm), total (ToA) and cortical (CtA) bone areas (mm), and estimated compressive bone strength (bone strength index; BSI, mg/mm) at the distal tibia.

Mindfulness-based yoga intervention for women with depression.

Objectives: The purpose of this study was to examine the efficacy of a 12-week mindfulness-based yoga intervention on depressive symptoms and rumination among depressed women.

Design: Prospective, randomized, controlled 12 week intervention pilot study. Depressive symptoms were assessed at baseline, post-intervention (12 weeks), and one-month follow-up.

Impaired cardiac and peripheral hemodynamic responses to inhaled β₂-agonist in cystic fibrosis.

Background: Pulmonary system dysfunction is a hallmark of cystic fibrosis (CF) disease. In addition to impaired cystic fibrosis transmembrane conductance regulator protein, dysfunctional β2-adrenergic receptors (β2AR) contribute to low airway function in CF. Recent observations suggest CF may also be associated with impaired cardiac function that is demonstrated by attenuated cardiac output (Q), stroke volume (SV), and cardiac power (CP) at both rest and during exercise.

Dementia alters standing postural adaptation during a visual search task in older adult men.

This study investigated the effects of dementia on standing postural adaptation during performance of a visual search task. We recruited 16 older adults with dementia and 15 without dementia. Postural sway was assessed by recording medial-lateral (ML) and anterior-posterior (AP) center-of-pressure when standing with and without a visual search task; i.

Healthy for life: a randomized trial examining physical activity outcomes and psychosocial mediators.

Background: Researchers theorize that interventions increase physical activity by influencing key theory-based mediators (e.g., behavioral processes).

Does television viewing predict dietary intake five years later in high school students and young adults?

Background: Prior research has found that television viewing is associated with poor diet quality, though little is known about its long-term impact on diet, particularly during adolescence. This study examined the associations between television viewing behavior with dietary intake five years later.

Methods: Survey data, which included television viewing time and food frequency questionnaires, were analyzed for 564 middle school students (younger cohort) and 1366 high school students (older cohort) who had complete data available at Time 1 (1998-1999) and five years later at Time 2 (mean age at Time 2, 17.

Prevalence of physical inactivity and recommended physical activity in community-based adults with mental retardation.

Little information has been reported on the leisure time physical activity (LTPA) habits of adults with mental retardation. Prevalence of physical inactivity and recommended LTPA of adults with mild to moderate mental retardation who live in community settings was described. Adults with mental retardation (76 men, 74 women) reported their physical activity habits.
