Purpose. To study the dynamics of interhemispheric interactions in children with friendly strabismus as a result of functional treatment. Material and methods. The study included 135 children aged 6 to 8 (average 6.8±0.1) years with convergent non-paralytic operated strabismus in combination with hypermetropic refraction and 96 children of the same age in the control group (average 7.1±0.1 years) without ophthalmic pathology. In children with strabismus, the leading hand and dominant eye were determined before and after functional treatment. Characteristics of spatial perception were evaluated by copying of complex geometric shapes which were Taylor's (right-handed) and Ray-Osterritz's (lefthanded). Results. After functional treatment in the group of children with non-paralytic strabismus, along with improved binocular functions and improved performance of the Taylor and Ray-Osterritz tests, there was an increase in the number of ambidextrous children and a significant decrease in the number of left-handers (p<0.001). Conclusion. The increase in the number of symmetrical lateral phenotypes against the background of improved binocular functions and spatial perception characteristics as a result of functional treatment of children with non-paralytic strabismus indicates an improvement of their interhemispheric interactions and can be an additional criterion for the ef fectiveness of treatment. Key words: lateral phenotypes, interhemispheric asymmetry, functional treatment of strabismus

Form rotation, figure directionality, and figure-ground discrimination were evaluated before and after 10 days of vestibular or aerobic exercises for 30 boys (7 to 12 yr.) who showed problems in learning, reading, and inattention. Eight subjects had normal vestibulo-ocular reflex (VOR) responses as determined by caloric and rotational testing. They were assigned to a vestibular program (Control Group I). The 22 subjects with abnormal VOR test responses were randomly assigned to either aerobic exercises (Experimental Group II) or a vestibular program (Experimental Group III). Spatial perceptual test scores varied widely, with the majority performing below age-expected norms but no significant differences on vestibular status appeared. Postexercise, only subjects completing the vestibular program made significant gains: Experimental Group III (abnormal VOR) made significant gains in accuracy and normal test responses compared to the other groups, and Control Group I made significantly greater gains in speed of spatial perceptual processing. For boys with problems in learning, reading, inattention, and vestibular function, a vestibular exercise program complementing a traditional or special educational program may enhance the spatial perceptual skills needed for reading.

In this chapter we demonstrate how older adults can benefit from novel technologies. One hundred and fourteen patients with MCI according to the revised Petersen criteria (Petersen, 2006), aged between 65 and 88 years, were recruited to participate in a Serious Game training (SG) and an Active Control group (AC). They benefited from neuropsychological testing and electroencephalography before and after the intervention. Our results showed that the SG group improved performance in specific cognitive functions such as working memory, dual task performance and visual conjunction search. The performance improvement was also supported only at the SG group by increased amplitude of the Event Related Potentials extracted from the electroencephalography measures. The results from our study suggest that older adults do not need to be technologically savvy to benefit from virtual reality training.

Conjunctival lymphomas are predominantly extranodal B-cell non-Hodgkin’s lymphomas (NHL), most of them are MALT-lymphomas originating from the mucosa-associated lymphoid tissue. The paper is devoted to the study of the feasibility of using hypercorrection in the functional treatment of children with non-paralytic strabismus.The purpose of this work is evaluation of the effectiveness of hypercorrection in the diagnosis and functional treatment of children with non-paralytic strabismus. Patients and methods. We observed 166 school-age children with friendly strabismus: 140 children with esotropia (134 children with hypermetropic refraction and 6 children with myopic refraction) and 26 children with exotropia (17 children with myopic refraction and 9 children with hypermetropic refraction). The control group of children included 151 school-age children with ametropia without strabismus: 110 children with hypermetropia and 41 children with myopia. Optimal optical correction, accommodation and visual acuity were studied under monocular observation conditions and then under bifixation control using a binarimeter at different distances from the eyes (0.5, 1, and 5 m).Results. In children with esotropia and hypermetropic refraction, the most favorable conditions for the formation of a binocular visual image (BVI) were created using hypercorrection (average values from 2.4 ± 0.06 to 2.8 ± 0.06 D for different distances from the eyes). Children with exotropia and myopic refraction also needed hypercorrection to form BVI (Me = 2.5 [Q1 = 2.0; Q3 = 3.0] D at all distances from the eyes). At the same time, a strong positive correlation was found between the deviation value and the hypercorrection value necessary for the formation of BVI in children with both esotropia and exotropua (r = 0.85, p < 0.001 and r = 0.8, p < 0.001, respectively). In children with “inappropriate” refraction (myopic with esotropia and hypermetropic — with exotropia), BVI was easier to occur and better maintained under hypocorrection by an average of 1.75 ± 0.06 d. In the control group of children, the maximum visual acuity under the control of BVI was observed with the strength of correcting lenses 0.5 D less compared to monocular conditions of the study.Conclusion. The effectiveness of using hypercorrection in children with non-paralytic strabismus and “appropriate” refraction for the formation of BVI on a binarimeter is shown. In this case, the value of hypercorrection has a direct dependence on the value of deviation, which is consistent with the principles of accommodation-convergent synkinesia. In children with non-paralytic strabismus and “inappropriate” refraction, more favorable conditions for the formation of BVI are created when using hypocorrection. The result of functional treatment on a binarimeter with an individual selection of optimal optics for performing exercises is an improvement of accommodation, binocular and stereo vision, an increase of fusion reserves and visual acuity.

AbstractIn this study the effect of a surface combat swimming (sCS) training program on performance in freestyle swimming and sCS was examined. Forty-five officer cadets were divided into three equivalent groups: a control group (CG), a group that was trained only with a swimsuit and fins (SF), and a group that was trained with combat uniform and equipment (UE). Groups SF and UE followed a 60-min training program with sCS for 4 weeks, 4 times per week. Before and after the training program all groups performed 4×50 and 400-m freestyle swimming, 250-m sCS with a uniform and equipment, 350-m with a swimsuit and fins, and 300-m with a swimsuit. The UE group showed improved performance in 4×50-m (mean±SD 14±9 s) and in 250-m sCS (24±14 s) (p<0.01). Both the SF group and the UE group improved in 300-m sCS, in 350-m sCS and in 400-m freestyle (p<0.05). We conclude that the training adaptations seemed to be specific, not only with regard to the activity performed, but also in terms of the actual conditions of an operation, which also include equipment.

Purpose Semi-occluded vocal tract (SOVT) exercises with tubes or straws have been widely used for a variety of voice disorders. Yet, the effects of longer periods of SOVT exercises (lasting for weeks) on the aging voice are not well understood. This study investigated the effects of a 6-week straw phonation in water (SPW) exercise program. Method Thirty-seven elderly subjects with self-perceived voice problems were assigned into two groups: (a) SPW exercises with six weekly sessions and home practice (experimental group) and (b) vocal hygiene education (control group). Before and after intervention (2 weeks after the completion of the exercise program), acoustic analysis, auditory–perceptual evaluation, and self-assessment of vocal impairment were conducted. Results Analysis of covariance revealed significant differences between the two groups in smoothed cepstral peak prominence measures, harmonics-to-noise ratio, the auditory–perceptual parameter of breathiness, and Voice Handicap Index-10 scores postintervention. No significant differences between the two groups were found for other measures. Conclusions Our results supported the positive effects of SOVT exercises for the aging voice, with a 6-week SPW exercise program being a clinical option. Future studies should involve long-term follow-up and additional outcome measures to better understand the efficacy of SOVT exercises, particularly SPW exercises, for the aging voice.

Abstract. This study measured the effect of emotional states on lexical decision task performance and investigated which underlying components (physiological, attentional orienting, executive, lexical, and/or strategic) are affected. We did this by assessing participants’ performance on a lexical decision task, which they completed before and after an emotional state induction task. The sequence effect, usually produced when participants repeat a task, was significantly smaller in participants who had received one of the three emotion inductions (happiness, sadness, embarrassment) than in control group participants (neutral induction). Using the diffusion model ( Ratcliff, 1978 ) to resolve the data into meaningful parameters that correspond to specific psychological components, we found that emotion induction only modulated the parameter reflecting the physiological and/or attentional orienting components, whereas the executive, lexical, and strategic components were not altered. These results suggest that emotional states have an impact on the low-level mechanisms underlying mental chronometric tasks.

SummaryChanges in platelets in 48 patients with uterine myoma before and after hysterectomy with and without ovariectomy were examined. Bilateral ovariectomy in 25 cases (ovariec-tomized group) and unilateral or non-ovariectomy in 23 cases (control group) were performed at the hysterectomy. Platelet count and an appearance rate of secondary aggregation decreased at one day after and increased at one week after the operation, similarly in both the ovariectomized and the control group. The appearance rate of secondary aggregation was reflected in an intensity of aggregation at 5 min after the addition of reagent to PRP. At one month after the operation, the appearance rate of secondary aggregation induced by 3 μM ADP showed a statistically significant decrease in comparison with the preoperation value (P <0.05) and the enhancement of 5-min aggregation was still observed in the control group, while ceased in the ovariectomized group. The difference between the two groups was significant (P < 0.05). There was almost no change in the speed and intensity of primary and secondary aggregation during the observation period. No significant differences in collagen-induced aggregation were noted between the two groups. The results suggest that ovarian hormones, mainly estrogen, facilitate platelet activation which is mediated by the so-called secondary aggregation.
