Tandem Gait

ObjectiveTo examine sex differences in TG performance among collegiate student-athletes acutely post-concussion relative to pre-injury performance.BackgroundPostural control impairments are common following concussion and traditionally assessed using the Balance Error Scoring System (BESS). Tandem gait (TG) has successfully identified impairments in postural control acutely post-concussion that were undetected by the BESS; thus, TG may be a more robust postural control assessment following concussion. While sex differences in BESS performance after concussion have been explored, there is no literature regarding sex differences in post-concussion TG.Design/MethodsForty-eight concussed collegiate student-athletes (30 females) and twenty-five healthy controls (13 females) completed TG tests during pre-season and again acutely post-concussion. Participants walked heel-to-toe down a 3-meter line, turned, and returned as quickly as possible, completing four single-task (ST) and dual-task (DT) TG trials. During DT trials, they simultaneously answered mini-mental style questions. The best ST and DT times were recorded. A 2 × 2 (group*sex) ANOVA was used to examine TG change between pre-injury and post-injury tests (positive value = slower/worsening; negative value = faster/improving).ResultsThe change in TG time from pre-injury to post-injury was significantly higher for the concussion group relative to the control group during both ST (Concussion: 1.6 ± 2.6 seconds, Controls: −1.1 ± 0.8 seconds, p < 0.001) and DT (Concussion: 2.0 ± 3.8 seconds, Controls: −0.9 ± 1.7 seconds, p < 0.001) TG. There were no significant interactions (ST: p = 0.17, DT: p = 0.23) or main effects for sex (ST: p = 0.63, DT: p = 0.91).ConclusionsThere were no sex-specific differences in TG performance acutely post-concussion. However, all concussed participants, regardless of sex, performed significantly worse on TG than male and female controls after injury relative to baseline, while controls did not demonstrate such a change. These results suggest that TG can appropriately identify postural control impairments following concussion; however, there do not appear to be differences in performance between males and females.

PURPOSE: To examine the effect of age on postural control outcomes among patients being seen during their initial post-concussion clinical visit. METHODS: Youth patients were seen≤14 days post-concussion, and completed a series of postural control evaluations: tandem gait, Romberg, and Balance Error Scoring System (BESS) tests. RESULTS: We included 109 children 8–12 years of age (24%female, evaluated median = 7 [interquartile range = 4–10] days post-injury) and 353 adolescents aged 13–18 years (36%female, evaluated median = 7 [4–10] days post-injury). There was a higher proportion of children who demonstrated abnormal tandem gait relative to adolescents (26%vs. 11%; p <  0.001). They also made more BESS errors in single (median = 5 [2–10] vs. 4 [2–6] errors) and tandem (median = 3 [1–6] vs. 2 [0–4]) firm stances. After covariate adjustment, children demonstrated worse tandem gait (adjusted odds ratio = 3.05, 95%CI = 1.68–5.53) and more firm surface BESS errors (double stance β=0.51, 95%CI = 0.22–0.80; single stance β= 1.18, 95%CI = 0.42–1.95; tandem stance β= 0.98, 95%CI = 0.28–1.68) than adolescents. CONCLUSIONS: Tandem gait and BESS performance following concussion differ in children compared to adolescents who present within 2 weeks of injury. Clinicians assessing and managing concussion should recognize age differences in postural control performance when assessing those with concussion.

Abstract Objective Traumatic brain injury (TBI) affects neurocognition. Speaking multiple languages can also influence cognitive test performances. We examined the relationship between TBI and monolingualism/bilingualism on a task of attention and response inhibition (Stroop Color Word Test; SCWT). Method The sample (N = 96) consisted of 37 healthy controls (19 bilingual; 18 monolingual), 32 acute TBI participants (12 bilingual; 20 monolingual), and 27 chronic TBI participants (16 bilingual; 11 monolingual). Acute TBI participants were tested 6 months post-injury and chronic TBI participants were tested 12 months or more post-injury. The SCWT included the word (SCWT-W), color (SCWT-C), and color-word interference (SCWT-I) conditions. All participants passed performance validity testing. 3X2 ANOVAs were conducted to examine the relationship between TBI and monolingualism/bilingualism on SCWT performances. Results Group effects (control and TBI groups) were found for all Stroop measures. We found main effects of TBI on SCWT-W, p = .013, ηp² = .09, SCWT-C, p = .001, ηp² = .14, and SCWT-I, p = .022, ηp² = .08, with the controls outperforming acute TBI survivors on SCWT-I, chronic TBI survivors on SCWT-W, and both TBI groups on SCWT-C. We also observed main effects of language for SCWT-C, p = .012, ηp² = .07, and SCWT-I, p = .003, ηp² = .09, with the monolinguals outperforming bilinguals on SCWT-C and SCWT-I. However, no significant interactions between TBI and language were found. Conclusion As expected, the control group outperformed TBI survivors on the SCWT. Monolinguals outperformed bilinguals on all Stroop measures except SCWT-W condition. Our findings seem to suggest that monolingual speakers may have better attention and response inhibition abilities that resulted in better SCWT performance.

BackgroundFemales are more likely than males to develop major depressive disorder (MDD). The current study used fMRI to compare the neural correlates of autobiographical memory (AM) recall between males and females diagnosed with MDD. AM overgenerality is a persistent cognitive deficit in MDD, the magnitude of which is correlated with depressive severity only in females. Delineating the neurobiological correlates of this deficit may elucidate the nature of sex-differences in the diathesis for developing MDD.MethodsParticipants included unmedicated males and females diagnosed with MDD (n = 20/group), and an age and sex matched healthy control group. AM recall in response to positive, negative, and neutral cue words was compared with a semantic memory task.ResultsThe behavioral properties of AMs did not differ between MDD males and females. In contrast, main effects of sex on cerebral hemodynamic activity were observed in left dorsolateral prefrontal cortex and parahippocampal gyrus during recall of positive specific memories, and middle prefrontal cortex (mPFC), and precuneus during recall of negative specific memories. Moreover, main effects of diagnosis on regional hemodynamic activity were observed in left ventrolateral prefrontal cortex and mPFC during positive specific memory recall, and dorsal anterior cingulate cortex during negative specific memory recall. Sex × diagnosis interactions were evident in the dorsomedial prefrontal cortex, caudate, and precuneus during positive memory recall, and in the posterior cingulate cortex, insula, precuneus and thalamus during negative specific memory recall.ConclusionsThe differential hemodynamic changes conceivably may reflect sex-specific cognitive strategies during recall of AMs irrespective of the phenomenological properties of those memories.

The Relationship

The present study is designed to address the relationship between postural sway and balance training. We compared postural sway in a group of trained dancers to a group of physically fit, untrained participants (control group) in order to assess enhanced postural control with balance training, particularly under challenging balance conditions. We varied the difficulty of postural control by using two surface conditions (rigid surface, foam surface) and two visual conditions (eyes open, eyes closed), factorially combined. The data were evaluated using 1-between (group) × 2-within (vision and surface) analyses of variance (ANOVA). The three dependent variables were the standard deviation of the COP time series in the anterior-posterior (AP) and medial-lateral (ML) axes, and the COP path length. Significant main effects were found for surface and vision and the surface*vision interaction in all conditions. Significant group differences were found in the AP and ML axes. The results of this study indicate that balance training enhances the control of posture. Thus, it may be useful to provide balance training to workers who must operate under conditions that threaten balance.

The sex differences of infection and inflammatory diseases particularly appear at reproductive age and depend on the sex hormone level, varied between male and female. There are a few sets of data about the sex differences of infection and inflammatory diseases course, including systemic inflammatory response syndrome (SIRS) and sepsis, of newborns. The aim of our research was the estimation of morphological and immunological manifestation of SIRS of the newborn Wistar rats. Investigations were carried out on male and female two-day-old Wistar rats (10–12 g). SIRS was modeled by intraperitoneal injection of LPS (E. coli, O26: B6 strain, Sigma) in high dose—15 mg/kg. We did not find out any sex differences of the liver lesions severity between newborn males and females after LPS injection. The levels of endotoxin and estradiol in the serum, as the number of neutrophils in the intra-alveolar septa of the lungs, were higher in males than females with SIRS. Production of IL-2 and TNF-α by the spleen cells of males was higher than that in control group that reflects polarization predominantly on the Th1-type immune response. The secretion of IL-2, TNF-α, and IFN-γ by ConA activated spleen cells of females decreased that reflects the suppression of Th1-type immune response. We suppose that the LPS administration in the high dose causes the multidirectional reaction of the immune system of neonatal males and females Wistar rats.

Abstract Objective Traumatic brain injury (TBI) is associated with a number of cognitive deficits. Language factors also impact neurocognitive performance. We examined the effects of TBI and bilingualism/monolingualism on a test of attention and executive functioning (Trail Making Test; TMT). Method The sample (N = 96) consisted of 36 healthy controls (19 bilingual; 17 monolingual), 34 acute TBI participants (12 bilingual; 21 monolingual), and 27 chronic TBI participants (16 bilingual; 11 monolingual). Acute TBI participants were tested 6 months post-injury and chronic TBI participants were tested 12 months or more post-injury. 3X2 ANOVAs were conducted to determine the effect of TBI and bilingualism/monolingualism on TMT part A and B. Results Main effects were found between groups (i.e., control and TBI groups) on TMT A, p < .001, ηp² = .17 and TMT B, p < .05, ηp² = .09. Pairwise comparisons revealed a difference only between the control group and the 6-month TBI group, with the latter performing worse. Main effects were found for bilingualism/monolingualism on TMT A, p < .05, ηp² = .04 and TMT B, p < .05, ηp² = .05; monolingual participants performed better than bilingual participants. No interactions emerged. Conclusion Relative to monolinguals, bilingual participants demonstrated worse attention and executive functioning performances 6 months post-TBI; however, 12 months post-TBI, the difference was negligible.

Main Effects

Learning disabled (LD) and nondisabled (ND) males and females at four grade levels (1, 3, 5 and 7) were compared on ten measures of figural and verbal creativity. No sex differences were found. In reference to figural creativity, originality was greater for the LD children at all grade levels, while elaboration was greater for the ND children at all grade levels. In reference to verbal creativity, group main effects in favor of the nondisabled were found; however, group x grade interactions revealed higher performance for the LD children at grade 1. This latter finding is discussed in terms of the possible effects of negative reactions of others (e.g., teachers, peers) to the unique verbalizations of young learning disabled children.

There are many reasons for postural disorder development, but dysfunction of the cervical spine muscles is the most disputable reason. The purpose of the study is to reveal the influence of latent myogenic trigger zones of the cervical muscles on postural resistance. Materials and Methods. The authors used the method of computer posturography. Latent myogenic trigger zones (LMTZs) were determined by an indurated nodule or bundle in the neck muscle and by hyperesthesia in this zona. Assessment of postural resistance in subjects with LMTZs was carried out using standard posturography tests and Romberg test. Both classical and vector indicators were evaluated in a standard sample. Results. In fact, only vector indicators changed significantly in subjects with multiple LMTZs (4 or more). Thus, a decrease in the equilibrium function quality was established, as well as an increase in the average linear velocity of the pressure center and an increase in the normalized vectorogram area if compared with the indices in the control group and the group with sporadic LMTZs (from 1 to 3). The obtained results indicate a postural control decrease in individuals with multiple LMTZs. Subjects with sporadic LMTZs demonstrated a significant decrease in classical and a number of vector indicators, which shows the improvement in postural resistance in this test group. In Romberg test, all subjects with LMTZs, regardless of the zone number, showed an increasd Romberg coefficient. Conclusion. Multiple LMTZs of cervical muscles can reduce postural stability through increased afferentation from the cervical proprioreceptors. It is more obvious during in case of eye control elimination. Keywords: latent myogenic trigger points, postural control, posturography, Romberg test. Выделяют множество причин развития постуральных нарушений, среди которых дисфункция мышц шейного отдела позвоночника является наиболее спорной. Цель исследования. Выявить влияние латентных миогенных триггерных зон шейной мускулатуры на постуральную устойчивость. Материалы и методы. Использовался метод компьютерной стабилографии. Латентные миогенные триггерные зоны (лМТЗ) определялись по наличию в мышце шеи уплотненного узелка или пучка и по повышенной болевой чувствительности в этой области. Оценка постуральной устойчивости у испытуемых с лМТЗ осуществлялась с помощью стандартного стабилографического тестирования и теста Ромберга. В стандартной пробе оценивались как классические, так и векторные показатели. Результаты. Показано, что у испытуемых с множественными лМТЗ (4 и более) достоверно изменяются только векторные показатели. Так, установлено снижение качества функции равновесия, а также повышение средней линейной скорости центра давления и увеличение нормированной площади векторограммы по сравнению показателями в группе контроля и группе с единичными лМТЗ (от 1 до 3), что указывает на снижение постурального контроля у лиц с множественными лМТЗ. У испытуемых с единичными лМТЗ отмечено достоверное снижение классических показателей и ряда векторных, что свидетельствует об улучшении постуральной устойчивости в данной группе испытуемых. В пробе Ромберга все субъекты с лМТЗ независимо от количества последних показали повышение коэффициента Ромберга. Выводы. Множественные лМТЗ шейной мускулатуры могут снизить постуральную устойчивость через усиление афферентации от шейных проприорецепторов, что наиболее выражено при элиминации зрительного контроля. Ключевые слова: латентные миогенные триггерные точки, постуральный контроль, стабилография, тест Ромберга.

Objective: Analyze postural control in the bipedal position as well as during gait and functional tests in patients with type 2 diabetes mellitus after supervised and unsupervised proprioceptive training. Design: A three-group randomized controlled trial. Setting: Physiotherapeutic Resources Lab, Department of Health Sciences, Ribeirão Preto Medical School, University of São Paulo Subjects: Eighty patients with type 2 diabetes allocated to three groups: control, home training, and supervised training. Interventions: The supervised and home training groups performed two weekly sessions of proprioceptive exercises for 12 weeks. The control group was not submitted to any of treatment. Main measures: Bipedal balance, gait, and performance on functional tests were evaluated before and after 12 weeks using the Balance Evaluation Systems Test (BESTest) and the force plate. Results: No significant improvements were found regarding postural control, gait, or performance on the functional tests, as evidenced by the inter-group comparisons of the total BESTest score [control: 90.7 (81.5–92.6); home training: 85.2 (77.8–90.3); supervised training: 88.4 (82.6–91.4), P > 0.05] as well as the tests performed on the force plate ( P > 0.05). The clinical effect size of the proposed intervention was less than 0.2, demonstrating no effect for the main outcome variable evaluated by the “Sensory Orientation” item of the BESTest and by the mCTSIB (pressure plate). Conclusions: The proposed proprioceptive training did not lead to improvements in postural control in patients with type 2 diabetes with no clinical signs of diabetic distal polyneuropathy when analyzed using the BESTest clinical evaluation and a force plate. Trial registration: NCT01861392 (clinicaltrials.gov).

Abstract Frailty may differentially impact how older adult males and females perceive sexual functioning, an important part of well-being. We assessed the level of frailty (robust, pre-frail, frail) for anyone with data on 11 sexual functioning questions asked in wave 2 of the National Social Life, Health, and Aging Project, 2010-2011 (n=2060). Questions covered five domains: overall sexual function (OSF), sexual function anxiety (SFA), changes in sexual function (CSF), erectile/vaginal dysfunction (EVD), and masturbation. Logistic regression identified sex differences in frailty and reporting worse sexual functioning. Linear regression predicted the number of domains reported as worse. Among males (n=1057), pre-frailty meant higher odds of reporting SFA (OR 1.8 95%CI 1.2-6.6), CSF (OR 1.7 95%CI 1.1-2.7), and EVD (OR 1.5 95%CI 1.0-2.2). Among females (n=1003), there was no difference in reporting by frailty. Females were more likely to report worse OSF (Robust: OR 7.4, 95%CI 4.8-11.4; Pre-frail: OR 6.2, 95%CI 3.9-9.9; Frail: OR 3.4 95%CI 1.7-6.6), but less likely to report SFA (Robust OR .3, 95%CI .2-.5; Pre-frail OR .2, 95%CI .1-.3; Frail OR .2 95%CI .1-.3). Pre-frail and frail females reported fewer domains as worse (Pre-frail coefficient -0.21 SE 0.09, Frail -0.43 SE 0.14). As frailty worsened, males reported more domains as worse (Pre-frail 0.24 SE 0.07, Frail 0.29 SE 0.08). Self-reported sexual functioning differs by sex at all levels of frailty, and reporting by males, but not females, changes with frailty. Providers should be aware that sexual functioning is of importance to both sexes despite varying degrees of frailty.
