Maģistra darbs ir uzrakstīts angļu valoda uz 47 lapām. Tas satur 28 attēlus, 2 tabulas un 42 atsauces uz literatūras avotiem. Maģistra darba mērķis ir nodemonstrēt optometrisko rehabilitācijas metožu ietekmi uz infantilu idiopātisko nistagmu (IIN). Desmit pacientiem ar IIN (30 ± 14 g.) tika veiktas sekojošas ārstēšanas metodes: prizmas ar bāzi uz āru, krāsotas kontaktlēcas (zīlītes diametrs 5 mm), audio-biofīdbeka metode. Pirms un pēc ārstēšanas tika novērtēts redzes asums un kontrastredze tālumā un stereoredze tuvumā ar labāko subjektīvo korekciju, nistagma apmlitūda un frekvence. Rezultāti parādīja, ka visas ārstēšanas metodes vienādi ietekmēja redzes asuma, nistagma amplitūdas un frekven…

A meta-analysis on heart rate variability biofeedback and depressive symptoms

2021

Heart rate variability biofeedback (HRVB) has been used for a number of years to treat depressive symptoms, a common mental health issue, which is often comorbid with other psychopathological and medical conditions. The aim of the present meta-analysis is to test whether and to what extent HRVB is effective in reducing depressive symptoms in adult patients. We conducted a literature search on Pubmed, ProQuest, Ovid PsycInfo, and Embase up to October 2020, and identified 721 studies. Fourteen studies were included in the meta-analysis. Three meta-regressions were also performed to further test whether publication year, the questionnaire used to assess depressive symptoms, or the interval of …

Can neurophysiological markers of anticipation and attention predict ADHD severity and neurofeedback outcomes?

2021

Abstract Neurophysiological measures of preparation and attention are often atypical in ADHD. Still, replicated findings that these measures predict which patients improve after Neurofeedback (NF), reveal neurophysiological specificity, and reflect ADHD-severity are limited. Methods We analyzed children’s preparatory (CNV) and attentional (Cue-P3) brain activity and behavioral performance during a cued Continuous Performance Task (CPT) before and after slow cortical potential (SCP)-NF or semi-active control treatment (electromyogram biofeedback). Mixed-effects models were performed with 103 participants at baseline and 77 were assessed for pre-post comparisons focusing on clinical outcome p…

Results of the smooth-muscle fold-over double-plasty (SMFD)

1986

Since 1980, when we developed substitute for the internal anal sphicter, the smooth-muscle fold-over double-plasty (SMFD-plasty), we have operated on seven children using this method, usually in combination with the pull-through procedure, and on five children after one or more previous operations. Since 1983, 11 cases with previous operations have undergone the modified “door-wing” SMFD-plasty. The results are excellent if the operation is used in primary combination with the pull-through procedure or if the “door-wing” modification is combined with reconstruction of the pelvic floor. It is also necessary that all cases undergo a biofeedback conditioning program.

Effect of a Biofeedback Intervention on Heart Rate Variability in Individuals With Panic Disorder: A Randomized Controlled Trial

2021

OBJECTIVE Some individuals with panic disorder (PD) display reduced heart rate variability, which may result in an increased risk of cardiovascular mortality. Heart rate variability-biofeedback (HRV-BF) training has been shown to improve the modulation of the autonomic activity. Therefore, this randomized controlled trial was conducted to investigate the effect of a four-week HRV-BF intervention in individuals with PD. Heart rate variability-biofeedback (HRV-BF) training improved the modulation of the autonomic activity. Therefore, with this randomized controlled trial we aimed to investigate the effect of a four-week HRV-BF intervention in people with PD. METHODS Thirty-six women and sixte…

Concept of an extracellular regulation of muscular metabolic rate during heavy exercise in humans by psychophysiological feedback.

1996

Efferent motor signals to skeletal muscles concern not only the space/ time pattern of motion, but also the setting of muscular performance and through this the control of the current metabolic rate. For an optimal adjustment of metabolic rate during heavy exercise-e.g. in athletic competitions-a feedback control system must exist, including a programmer that takes into consideration a finishing point (teleoanticipation). The presented experiments, using Borg's scale, indicate the existence and functioning of a system for optimal adjustment of performance during heavy exercise and the relevance of teleoanticipatory effects. Thus motor learning includes not only somatosensory control, but al…
