Etiology of Exercise Injuries in Firefighters: A Healthcare Practitioners' Perspective.

The purpose of this study was to query healthcare practitioners (HCPs) who treat firefighter injuries to identify risk factors and mechanisms associated with musculoskeletal injuries during exercise. A phenomenological design was utilized to understand the experiences of HCPs while treating firefighters' musculoskeletal injuries due to exercise. Semi-structured interviews were conducted with 14 HCPs. Two interviews were pilot-tested with HCPs to ensure reliability and validity. Interviews were transcribed and uploaded to a qualitative analysis software program. Although the study inquired about injuries incurred by any exercise modality (e.g., endurance and resistance training), injuries induced during resistance training were prominent among HCPs as resistance training emerged as a primary exercise injury mechanism. HCPs indicated that the back and shoulder were prevalent anatomical exercise injury locations. Risk factors for exercise injuries included age, immobility, movement proficiency, and factors associated with fatigue. Exercise injury mechanisms included poor resistance training technique and overexertion. These findings could guide exercise program design, use of movement assessments, and the identification of other countermeasures to decrease the risk of resistance training exercise injuries among firefighters.

Exploring a Novel Tool to Measure Wandering Behavior in the Early Childhood Classroom.

Wandering, or random movement, affects cognitive and social skills. However, we lack methods to objectively measure wandering behavior. The purpose of this pilot study was to explore the use of the Ubisense real-time location system (RTLS) in an early childhood setting to explore wandering in typically developing (TD) children (n = 2) and children with or at risk for developmental disabilities (WA-DD; n = 3). We used the Ubisense RTLS, a tool for capturing locations of individuals in indoor environments, and Fractal Dimension (FD) to measure the degree of wandering or the straightness of a path. Results of this descriptive, observational study indicated the Ubisense RTLS collected 46,229 1-s location estimates across the five children, and TD children had lower FD (M = 1.36) than children WA-DD (M = 1.42). Children WA-DD have more nonlinear paths than TD children. Implications for measuring wandering are discussed.

Automated Measures to Understand Communication Opportunities for Young Children With Autism in the Community: A Pilot Study.

Community participation is vital to children's development and provides opportunities to practice social communication skills. Although previous studies suggest that young children with autism spectrum disorders (ASD) experience decreased community participation, there is little empirical evidence on the precise patterns of participation that may influence social communication opportunities. Therefore, this pilot study investigated the communication among families of children with ASD ( n = 5) versus typical development (TD; n = 5) across various community locations. We used automated, objective measures: the Language ENvironmental Analysis (LENA) system™ to measure the amount of communication and integrated this with a Global Positioning System (GPS; that is, Qstarz™) to measure community location. Results showed that families of children with ASD and TD spent a similar amount of time in community locations; however, there were differences in the amount of adult talk directed toward children with ASD versus TD across community locations. Findings suggest that automated measures may be successfully integrated to quantify social communication during community participation.
