Consideration of the neuromodulatory effects of EF may inform its clinical utility in addressing neuroplastic impairments after musculoskeletal injuries. We aimed to determine whether electrocortical activity and balance performance changed with attentional foci that prioritized differing sensory feedback and whether changes in electrocortical activity and balance were associated. Methods Individuals who were healthy (n = 15) performed a single-limb balance task under 3 conditions: internal focus (IF), somatosensory focus [EF with a baton (EF-baton)], and visual focus [EF with a laser (EF-laser)]. Electrocortical activity and postural sway were recorded concurrently using electroencephalography and a triaxial force plate. Electroencephalographic signals were decomposed, localized, and clustered to generate power spectral density in θ and α-2 frequency bands. Postural sway signals were analyzed with center-of-pressure sway metrics (eg, area, distance, velocity) and knee angle. The relationship between percent change in clustered brain activity and task performance metrics was assessed. Results Both EF conditions resulted in increased cortical activity and improved balance performance compared to IF. EF-laser had the largest effect, demonstrating increased frontal θ power (d = 0.64), decreased central θ power (d = −0.30), and decreased bilateral motor, bilateral parietal, and occipital α-2 power (d = −1.38 to −4.27) as well as a shorter path distance (d = −0.94) and a deeper (d = 0.70) and less variable (d = −1.15) knee angle than IF. Weak to moderate associations exist between increases in cortical activity and improved balance performance (ρ = 0.405–0.584). Conclusions EF resulted in increased cortical activity associated with cognitive, motor, somatosensory, and visual processing. EF-laser, which prioritized visual feedback, had the largest and broadest effects. Changes in cortical activity resulting from EF were independently associated with improved balance performance. Impact This study demonstrates that goal-oriented attention results in functional increases in brain activity compared to internally directed self-focus. These results suggest EF may target neurophysiologic impairments and improve balance in clinical populations. }}, author = {{Sherman, David A and Lehmann, Tim and Baumeister, Jochen and Gokeler, Alli and Donovan, Luke and Norte, Grant E}}, issn = {{0031-9023}}, journal = {{Physical Therapy}}, keywords = {{Physical Therapy, Sports Therapy and Rehabilitation}}, publisher = {{Oxford University Press (OUP)}}, title = {{{External Focus of Attention Influences Cortical Activity Associated with Single Limb Balance Performance}}}, doi = {{10.1093/ptj/pzab223}}, year = {{2021}}, } @article{32434, abstract = {{Whereas initial findings have already identified cortical patterns accompanying proprioceptive deficiencies in patients after anterior cruciate ligament reconstruction (ACLR), little is known about compensatory sensorimotor mechanisms for re-establishing postural control.

A total of 12 patients after ACLR (25.1 ± 3.2 years, 178.1 ± 9.7 cm, 77.5 ± 14.4 kg) and another 12 gender, age, and activity matched healthy controls participated in this study. All subjects performed 10 × 30 s. single leg stances on each leg, equipped with 64-channel mobile electroencephalography (EEG). Postural stability was quantified by area of sway and sway velocity. Estimations of the weighted phase lag index were conducted as a cortical measure of functional connectivity. The findings showed significant group × leg interactions for increased functional connectivity in the anterior cruciate ligament (ACL) injured leg, predominantly including fronto−parietal [F(1, 22) = 8.41, p ≤ 0.008, η2 = 0.28], fronto−occipital [F(1, 22) = 4.43, p ≤ 0.047, η2 = 0.17], parieto−motor [F(1, 22) = 10.30, p ≤ 0.004, η2 = 0.32], occipito−motor [F(1, 22) = 5.21, p ≤ 0.032, η2 = 0.19], and occipito−parietal [F(1, 22) = 4.60, p ≤ 0.043, η2 = 0.17] intra−hemispherical connections in the contralateral hemisphere and occipito−motor [F(1, 22) = 7.33, p ≤ 0.013, η2 = 0.25] on the ipsilateral hemisphere to the injured leg. Higher functional connectivity in patients after ACLR, attained by increased emphasis of functional connections incorporating the somatosensory and visual areas, may serve as a compensatory mechanism to control postural stability of the injured leg in the early phase of rehabilitation. These preliminary results may help to develop new neurophysiological assessments for detecting functional deficiencies after ACLR in the future.}}, author = {{Lehmann, Tim and Büchel, Daniel and Mouton, Caroline and Gokeler, Alli and Seil, Romain and Baumeister, Jochen}}, issn = {{1662-5161}}, journal = {{Frontiers in Human Neuroscience}}, keywords = {{Behavioral Neuroscience, Biological Psychiatry, Psychiatry and Mental health, Neurology, Neuropsychology and Physiological Psychology}}, publisher = {{Frontiers Media SA}}, title = {{{Functional Cortical Connectivity Related to Postural Control in Patients Six Weeks After Anterior Cruciate Ligament Reconstruction}}}, doi = {{10.3389/fnhum.2021.655116}}, volume = {{15}}, year = {{2021}}, } @article{32435, abstract = {{Abstract Mobile Electroencephalography (EEG) provides insights into cortical contributions to postural control. Although changes in theta (4–8 Hz) and alpha frequency power (8–12 Hz) were shown to reflect attentional and sensorimotor processing during balance tasks, information about the effect of stance leg on cortical processing related to postural control is lacking. Therefore, the aim was to examine patterns of cortical activity during single-leg stance with varying surface stability. EEG and force plate data from 21 healthy males (22.43 ± 2.23 years) was recorded during unipedal stance (left/right) on a stable and unstable surface. Using source-space analysis, power spectral density was analyzed in the theta, alpha-1 (8–10 Hz) and alpha-2 (10–12 Hz) frequency bands. Repeated measures ANOVA with the factors leg and surface stability revealed significant interaction effects in the left (p = 0.045, ηp2 = 0.13) and right motor clusters (F = 16.156; p = 0.001, ηp2 = 0.41). Furthermore, significant main effects for surface stability were observed for the fronto-central cluster (theta), left and right motor (alpha-1), as well as for the right parieto-occipital cluster (alpha-1/alpha-2). Leg dependent changes in alpha-2 power may indicate lateralized patterns of cortical processing in motor areas during single-leg stance. Future studies may therefore consider lateralized patterns of cortical activity for the interpretation of postural deficiencies in unilateral lower limb injuries.}}, author = {{Büchel, Daniel and Lehmann, Tim and Ullrich, Sarah and Cockcroft, John and Louw, Quinette and Baumeister, Jochen}}, issn = {{0014-4819}}, journal = {{Experimental Brain Research}}, keywords = {{General Neuroscience}}, number = {{4}}, pages = {{1193--1202}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Stance leg and surface stability modulate cortical activity during human single leg stance}}}, doi = {{10.1007/s00221-021-06035-6}}, volume = {{239}}, year = {{2021}}, } @article{35626, author = {{Büchel, Daniel and Lehmann, Tim and Sandbakk, Øyvind and Baumeister, Jochen}}, issn = {{2045-2322}}, journal = {{Scientific Reports}}, keywords = {{Multidisciplinary}}, number = {{1}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{EEG‑derived brain graphs are reliable measures for exploring exercise‑induced changes in brain networks}}}, doi = {{10.1038/s41598-021-01494-x}}, volume = {{11}}, year = {{2021}}, } @article{43016, author = {{Möhring, Julia and Krumhöfner, Anika and Gräfin von Plettenberg, Elisabeth Gudila Sophia Ida Maria}}, journal = {{-}}, publisher = {{Reinhard Mohn Stiftung, Kreissportbund Gütersloh e.V., Bezirksregierung Detmold}}, title = {{{Bewegungsförderung in Ganztagsschulen}}}, year = {{2021}}, } @article{37830, abstract = {{ZusammenfassungJegliche Art von Emotionen im Sport spielen vor allem in Wettkampfsituationen eine bedeutende Rolle, wenn es darum geht, zu einem bestimmten Zeitpunkt die optimale Leistung abzurufen.

In several kinds of sports, deceptive actions are used to hinder the anticipation performance of an opponent. During a head fake in basketball, a player turns the head to one side but passes the ball to the other side. A pass with a head fake generates a head-fake effect in the observer, which is characterized by slower and more error-prone responses to the pass direction as compared to passes without a head fake. Whereas the head-fake effect has been replicated several times, the question of its origin with dynamic stimuli has not been answered yet. The present study includes four experiments, which are conducted to examine the perceptual-cognitive mechanism underlying the effect by using the model of dimensional overlap ( Kornblum et al., 1990 ) and the additive factors logic ( Sternberg, 1969 ). Results point to multiple processes contributing to the head-fake effect for dynamic stimuli, which operate not only at a perceptual level but also at a level of response selection. }}, author = {{Polzien, Andrea and Güldenpenning, Iris and Weigelt, Matthias}}, issn = {{1618-3169}}, journal = {{Experimental Psychology}}, keywords = {{General Psychology, Arts and Humanities (miscellaneous), Experimental and Cognitive Psychology, General Medicine}}, number = {{6}}, pages = {{349--363}}, publisher = {{Hogrefe Publishing Group}}, title = {{{Examining the Perceptual-Cognitive Mechanism of Deceptive Actions in Sports}}}, doi = {{10.1027/1618-3169/a000503}}, volume = {{67}}, year = {{2021}}, } @article{46720, author = {{Polzien, Andrea and Güldenpenning, Iris and Weigelt, Matthias}}, journal = {{Plos one}}, number = {{5}}, pages = {{e0251117}}, publisher = {{Public Library of Science San Francisco, CA USA}}, title = {{{A question of (perfect) timing: A preceding head turn increases the head-fake effect in basketball}}}, doi = {{https://doi.org/10.1371/journal.pone.0251117}}, volume = {{16}}, year = {{2021}}, } @inproceedings{37842, author = {{Krause, Daniel and Margraf, Linda and Weigelt, Matthias}}, publisher = {{Journal of Sport & Exercise Psychology, 43 }}, title = {{{Neural Correlates of Augmented Feedback Processing are Associated to Short-Term Behavioral Changes and Automaticity in Motor Learning}}}, year = {{2021}}, } @inproceedings{38074, author = {{Krause, Daniel and Margraf, Linda and Weigelt, Matthias}}, editor = {{Huckauf, Anke and Baumann, Martin and Ernst, Marc and Herbert, Cornelia and Kiefer, Markus and Sauter, Marian}}, location = {{ Ulm}}, title = {{{Predictive value of valence-dependent neural correlates of augmented feedback processing for behavioral adaptation and learning in extensive motor learning}}}, year = {{2021}}, } @inproceedings{37840, author = {{Margraf, Linda and Krause, Daniel and Weigelt, Matthias}}, publisher = {{Journal of Sport & Exercise Psychology, 43}}, title = {{{Neural Processing of Augmented Feedback is Valence-Dependent and Changes After Extensive Practice of a New Motor Task}}}, year = {{2021}}, } @inproceedings{38078, author = {{Margraf, Linda and Krause, Daniel and Weigelt, Matthias}}, editor = {{Huckauf, Anke and Baumann, Martin and Ernst, Marc and Herbert, Cornelia and Kiefer, Markus and Sauter, Marian}}, location = {{Ulm}}, title = {{{Changes in valence-dependent neural correlates of augmented feedback processing after extensive motor sequence learning}}}, year = {{2021}}, }
