Background: Growing evidence indicates early exercise may improve symptoms and reduce clinical recovery time after concussion, but research examining collegiate student-athletes is scarce.

Objective: The aim of this study was to compare symptom recovery time, clinical recovery time, and persisting post-concussion symptom (i.e.

Purpose: This study summarizes experiences and perceptions of parents whose children received physical therapy for idiopathic toe walking (ITW) to inform clinical practice guideline development and identify perceived strengths and gaps in care.

Methods: A US-based survey was distributed to parents of children with ITW. Data from 98 respondents were compiled through descriptive statistics of item responses and review of comments.

Background: Concussed patients have impaired reaction time (RT) and cognition following injury that may linger and impair driving performance. Limited research has used direct methods to assess driving-RT post-concussion. Our study compared driving RT during simulated scenarios between concussed and control individuals and examined driving-RT's relationship with traditional computerized neurocognitive testing (CNT) domains.

Context: Dry cupping therapy is a noninvasive treatment commonly used to reduce pain and promote the healing process in various populations, including those with nonspecific neck pain; however, no data are available to support most of this method's true physiological benefits.

Objective: To determine if dry cupping therapy decreased pain and increased subcutaneous blood flow compared with sham cupping and control conditions.

Design: Controlled laboratory study.

Post-concussion sleep disturbances can be debilitating and may influence days to symptom recovery; however, evidence is minimal. The purpose of this study was to explore relationships between days to symptom recovery and aspects of sleep, as measured by actigraphy and subjective sleep questionnaires in a concussed sample. Thirty-one college students were physician-diagnosed with a concussion and asked to complete a daily sleep symptom checklist.

Context: Comprehensive assessments are recommended to evaluate sport-related concussion (SRC). The degree to which the King-Devick (KD) test adds novel information to an SRC evaluation is unknown.

Objective: To describe relationships at baseline among the KD and other SRC assessments and explore whether the KD provides unique information to a multimodal baseline concussion assessment.

Currently, air permeable chemical/biological (CB) protective garments are based on activated carbon technology, which reduces moisture vapor transport needed for evaporative cooling and has potential to absorb and concentrate toxic materials. Researchers are exploring classes of sorbent materials that can selectively accumulate and decompose target compounds for potential to enhance protective suits and allow for novel filtration devices. Here, the metal-organic frameworks (MOFs) UiO-66-NH and HKUST-1 have been identified as such materials.

Study Objectives: To describe sleep 2-3 days postconcussion through symptom recovery and make comparison to well-matched nonconcussed controls.

Methods: Twenty college students were physician diagnosed with a concussion and compared with 20 nonconcussed controls matched on age, sex, physical activity, and sleep quality. A wrist-worn ActiGraph GT9X Link was provided during initial evaluation (within 72 hr postinjury for concussed) and worn continuously until symptom resolution (duration matched for nonconcussed).

Objective: To explore differences in baseline King-Devick Test (KD) completion time between 2 testing modalities: (1) spiral-bound paper cards (cards) and (2) iPad application (iPad).

Design: Cross-sectional cohort analysis.

Setting: National Collegiate Athlete Association (NCAA) institutions.

Article Synopsis
  • Metal-organic frameworks (MOFs), particularly UiO-66, are being researched for their ability to decontaminate chemical warfare agents, which has attracted military interest.
  • The challenge with MOFs is their powder form, prompting studies on integrating them into fabrics to create multifunctional, protective clothing.
  • The developed poly(vinylidene) fluoride/Ti(OH) composite fabric, enhanced with triethanolamine (TEA), demonstrated effective moisture vapor transport and catalytic activity against various chemical agents, indicating promising applications for chemical protective wear.

Background: A student-athlete's mental state, including history of trait anxiety and depression, or current psychological state may affect baseline concussion assessment performance.

Purpose: (1) To determine if mental illness (anxiety, depression, anxiety with depression) influences baseline scores, (2) to determine if psychological state correlates with baseline performance, and (3) to determine if history of concussion affects Brief Symptom Inventory-18 (BSI-18) subscores of state anxiety, depression, and somatization.

Study Design: Cross-sectional study; Level of evidence, 3.

Background: Individuals who sustain their first concussion during childhood may be at greater risk of sustaining multiple concussions throughout their lifetime because of a longer window of vulnerability. This article aims to estimate the association between age at first concussion and number of subsequent concussions.

Patients And Methods: A total of 23,582 collegiate athletes from 26 universities and military cadets from three military academies completed a concussion history questionnaire (65% males, age 19.

Post-concussion impairments may result in unsafe driving performance, but little research is available to guide consensus on when concussed individuals should return to driving. The purpose of this study was to compare driving performance between individuals with and without a concussion and to explore relationships between neuropsychological and driving performance. Fourteen participants with concussion (age 20.

The influence of factors such as a cerebral injury characteristics, education, perceptual organization skills, and speed of information processing on performance on the Rey Complex Figure Test & Recognition Trial (RCF) was examined by means of hierarchical regression analyses in 100 consecutively referred persons with traumatic brain injury at a median of 2.5 months post-injury. Patients with premorbid (e.

It has been suggested that a ratio score of part B to part A of the Trail Making Test (TMT) may have clinical utility as a measure of cognitive efficiency and/or dissimulation. We investigated the clinical utility of the TMT B/A ratio score in the evaluation of patients with traumatic brain injury. Part B of the TMT demonstrated a statistically significant difference between groups with mild (n = 59) versus moderate-severe (n = 41) injuries.
