BACKGROUND: The present study developed a head-mounted display with the visual direction of a web camera modified to the right as a left unilateral spatial neglect (USN) model with respect to postural balance control. AIM: We aimed to estimate the validity and reliability of center of pressure (CoP) measurements in static standing balance (SSB) and dynamic standing balance (DSB) of healthy participants were using the USN model and to examine whether this model's use influenced postural balance control. METHOD: A portable CoP force plate was used to quantify postural balance control in 64 healthy participants as the model. The CoP displacement of the non-USN and USN models in the medial-lateral (ML) and anterior-posterior (AP) planes, CoP length, and bilateral load ratio in SSB and DSB to the right (R) and left (L) were evaluated. RESULTS: Regression analysis indicated that most CoP measurements have excellent concurrent validity. Bland–Altman plots showed good agreement between the non-USN and USN models in the CoP measurements. Test-retest reliability estimation between two times measurements varied in the frontal and sagittal planes. A Comparison of the results demonstrated that the CoP-AP and CoP length changed (-1.40% and 7.67%, respectively) significantly in SSB (P<0.05). Moreover, the CoP-AP changed very significantly in DSB-R and DSB-L (-1.50% and 1.86%, respectively) in opposite directions (P<0.01) when the subjects performed as the model. CONCLUSION: CoP measurements are valid and reliable to quantify standing balance control in both non-USN and USN models that appear to modulate changes in postural adaptation and adjustment.

BACKGROUND: Previous studies suggest better visual-spatial processing when participants are tested in postures in which dynamic stability is challenged. The question arises if this is also true for the performance in mental body-rotation tasks (MBRT). AIM: Taking the embodied cognition approach into account, the first aim of the present study was to examine the potential influence of different demands on dynamic stability for two postures (parallel stand vs. tandem stand) on solving two versions of the MBRT, inducing either an object-based or an egocentric perspective transformation strategy. The second aim was to investigate if these different demands on dynamic stability are reflected in postural sway parameters. METHOD: Thirty participants (18 females and 12 males) were tested in the two MBRTs and in a control condition. All tasks were performed while standing on a balance beam in tandem stand and in a feet parallel position on a force plate. RESULTS: The results for response time and response error revealed effects of rotation angle and task, but no effect of posture. The analyzed Center of Pressure (CoP) data revealed a reduction of body sway during the MBRT for egocentric perspective transformations. CONCLUSION: The results indicate that participants performed better for egocentric than for object-based transformations and that the egocentric transformation leads to more postural stability than the object-based.

BACKGROUND: Despite the literature positing a strong relation between motor performance and self-efficacy, few studies address the phenomenon formally. In this sense, how self-efficacy modulates corrections in a trial-to-trial basis and how the performance that individuals consider to be satisfactory modulate both corrections and self-efficacy are not well understood. AIM: The aim of this study is to develop and evaluate a model that relates self-efficacy and performance through a system of difference equations. METHOD: First, we demonstrate the model’s capabilities through constrained simulations. The, to evaluate the model’s grasp of empirical data, we parameterized the model to capture the constant, variable error, self-efficacy and believed satisfactory performance for each individual. RESULTS: The model demonstrates capacity to reproduce these summary results when initial conditions are fed to the system of difference equations. However, we observe features that must be improved and qualitative deviations when individuals demonstrate highly variable behavior. CONCLUSION: The initial results support the current assumptions and included variables in this model.

BACKGROUND: External focus of attention (FOA) promotes enhanced performance and learning in comparison to internal FOA; however, several dimensions associated with external FOA appear to have varying influence on motor skill performance. AIM: The purpose of this study was to investigate whether an attainability aspect of external FOA elicits enhanced standing long jump performance. METHOD: Fifteen healthy males performed standing long jumps in the following conditions: without a visual target (Tno), target placed at maximum distance (Tmax), and a target placed 10% beyond maximum distance (Tmax+10). Jump distances were measured, and kinetic data were recorded using a force platform. RESULTS: One-way ANOVA showed significantly greater jump distances for Tmax+10 compared to Tno and Tmax (p < 0.01). Additionally, the impulse of the ground reaction force (GRFimpulse) in the anterior-posterior direction was significantly greater for Tmax and Tmax+10 compared to Tno (p < 0.05). CONCLUSION: Thus, an external FOA tailored to individual ability benefits standing long jump performance. Overall, the findings support the approach of adopting an external FOA with an emphasis on targets that are specific to the individual and based on attainability.

BACKGROUND: Validated tests for the quality of movement patterns are important to help teachers to assess and induce positive performance changes. However, few tests are available for handball sport skills. AIM: Therefore, we developed and validated a checklist to assess dribbling with a jumping throw. METHOD: First, three handball experts were invited to verify if the checklist which contained all the components that describe the skills, and the logical validity process. Then, fifty participants, aged 8 -12 years old, performed the skill of dribbling with a horizontal jumping throw, fifteen of them were re-tested one week apart. Two raters were also selected to conduct an intra- and inter-rater objectivity assessment. McNemar tests were used to compare the proportion of proficient and non-proficient performance between raters. Cohen’s k tests were used to test the intra and inter-rater objectivity. The intra-class correlation coefficient was used to estimated reliability (test-retest). RESULTS: The results confirmed that the checklist contained the necessary criteria to characterize the skill and to discriminate children with different proficiency levels. Moderate-to-high inter-and intra-rater agreements were found. Children's performance pre and post-test were highly reliable. CONCLUSION: In conclusion, the proposed checklist can reliably analyze the movement pattern of the dribbling with horizontal jumping throw – which can be highly useful for teachers and sports coaches.

Background: Although previous studies targeted S1 by TMS to investigate its effect on the corticospinal pathway, there is no evidence if such stimuli produced by TMS would distinctly be restricted to it and not reach M1 interneurons adjacent to S1.Aim: We hypothesized that S1 vs. M1 stimulation-induced MEPs would be similar but smaller and less variable due to the focality of the magnetic pulse, considering that even if TMS is neuronavigated, the magnetic field is not selective enough and reaches M1 interneurons.Method: Healthy volunteers (n = 8, 2 females, age: 29.9 ± 5.49y) received single-pulse TMS over each hemisphere at each intensity of 90, 100, 110, and 120% of rMT in a randomized order. MEPs from the contralateral FCR were recorded.Results: We found no interhemispheric differences, but larger peak-to-peak amplitudes and variability of MEPs after M1 as compared to S1 stimulation. However, latency and waveforms of MEPs did not differ between S1 vs. M1 stimulation supporting the idea that TMS over S1 is not selective enough and can excite M1 interneurons thus producing MEPs on the contralateral FCR.Interpretation: Future studies should carefully consider these results when targeting S1 with TMS even if using a neuronavigation system.

BACKGROUND: The development of research has not followed the increase in the number of Pilates practitioners. So, due to the popularity of the Pilates Method, especially among women, studies that verify the effects of exercises are important. AIM: To verify the effect of 30 sessions of the Pilates Method on static body posture, postural habits, body image perception and dynamic balance in healthy adult women. METHOD: This is a quasi-experimental study, characterized by a 15-week Pilates exercise intervention program, twice a week. Outcomes static body posture, postural habits, body image perception, and dynamic balance were evaluated in three moments: 30 days before the intervention started (M1), just before the intervention started (M2) and ended (M3). RESULTS: Nineteen healthy women [26.8 (3.5) years, 57.9 (6.8) kg, 160.6 (6.9) cm] participated in the study. There were differences in M2 compared to M3, and this represented an increase in the balance score (p<0.001), in the proportion of individuals with aligned trunk postural balance (p=0.002), in the proportion of individuals with a neutral pattern to pick up an object from the floor (p<0.025), and a decrease in the perception of distance between trochanters (p=0.037). CONCLUSION: Thirty Pilates sessions practiced twice a week by healthy adult women can improve dynamic balance, the postural habit of pick up an object from the floor, and static body posture.
