The Timed Up and Go (TUG) Test is recommended by the U.S. Centers for Disease Control and Prevention as an easy to administer clinical test to evaluate a senior citizen's fall risk. Limited evidence has been presented in the literature validating the TUG Test. In this study we sought to assess correlations between the TUG Test and various balance markers utilizing the OptoGait system. Fifty-one healthy seniors completed randomized trials of the TUG Test and a Gait Test utilizing OptoGait photoelectric technology. Correlations among mean and standard deviation values for these variables and TUG performance were calculated. Utilizing a Bonferroni adjustment and an alpha level of .05, eight significant correlations of a moderately strong degree (absolute r scores between .51 and .78) emerged. Correlation results indicate that the TUG Test is a valid tool for screening balance deficits that lead to increased fall risk in senior citizens.

Purpose Interventions for speech disorders aim to produce changes that are not only acoustically measurable or perceptible to trained professionals but are also apparent to naive listeners. Due to challenges associated with obtaining ratings from suitably large listener samples, however, few studies currently evaluate speech interventions by this criterion. Online crowdsourcing technologies could enhance the measurement of intervention effects by making it easier to obtain real-world listeners' ratings. Method Stimuli, drawn from a published study by Sapir et al. (“Effects of intensive voice treatment (Lee Silverman Voice Treatment [LSVT]) on vowel articulation in dysarthric individuals with idiopathic Parkinson disease: Acoustic and perceptual findings” in Journal of Speech, Language, and Hearing Research, 50 (4), 2007), were words produced by individuals who received intensive treatment (LSVT LOUD) for hypokinetic dysarthria secondary to Parkinson's disease. Thirty-six online naive listeners heard randomly ordered pairs of words elicited pre- and posttreatment and reported which they perceived as “more clearly articulated.” Results Mixed-effects logistic regression indicated that words elicited posttreatment were significantly more likely to be rated “more clear.” Across individuals, acoustically measured magnitude of change was significantly correlated with pre–post difference in listener ratings. Conclusions These results partly replicate the findings of Sapir et al. (2007) and demonstrate that their acoustically measured changes are detectable by everyday listeners. This supports the viability of using crowdsourcing to obtain more functionally relevant measures of change in clinical speech samples. Supplemental Material https://doi.org/10.23641/asha.12170112

Objective: This study sought to investigate correlations between OptoGait motion analysis technology and 2 commonly used concussion assessment instruments, the Balance Evaluation Scoring System (BESS) and the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) computerized neurocognitive assessment software, to see if OptoGait might be a valid concussion assessment tool. Methods: Twenty Division-1 college women varsity soccer players completed trials of 8 different conditions of the OptoGait test battery. Then participants completed the BESS and ImPACT tests. One hundred twenty-eight total spatiotemporal variables were recorded for each trial of OptoGait. Pearson's r correlations among these variables and BESS and ImPACT results were calculated, and pattern analysis was completed to evaluate for emergent patterns in the data. Results: Correlations for the 8 OptoGait mean-score subtests were related to the balance double-leg foam test (BESS). Correlations for the 8 OptoGait mean-score subtests were related to the balance double-leg foam test (BESS), and correlations between OptoGait standard deviation measures and the balance tandem hard surface test (BESS) both indicated potentially significant patterns. No consistent patterns of correlation existed between the OptoGait variables and the ImPACT results. Conclusion: OptoGait conditions correlate at higher than predicted rates with subtests of the BESS instruments but not the ImPACT measures. (J Chiropr Med 2017;16:163-169)

Object control skills (OCS) provide children the means to be physically active. However, gender equality in some OCS remains elusive. Particularly troublesome is the basic throwing pattern and, by extension, the striking pattern, both of which rely on forceful, rapid rotation of the pelvis, trunk, and shoulders. Some scholars argue that sex differences in throwing and striking are rooted in human evolution. The purpose of this study was to examine development of throwing and striking at the fundamental movement level. The design was multi-cohort sequential: 280 boys and girls grades K–8 (ages 4–15) were tested up to three times per year for 5 years on the Test of Gross Motor Development (TGMD-2). Hierarchical linear modeling (HLM) was applied to analyze individual growth curves. As anticipated, significant (p < .001) age-related gains were found for throwing and striking. In terms of sex (biology) or gender (sociocultural) differences, boys performed better longitudinally at throwing (p < .05) and striking (p < .05). These results reinforce theories that girls may be disadvantaged in achieving proficiency in throwing and striking. Interventions designed to enhance development of these skills should be in place long before grade 4, when most physical education curricula transitions to games and sports.
