Abstract Background To observe the characteristics of binocular integration and stereopsis in children with television torticollis. Methods A retrospective study was carried out, where data were collected from 25 children with television torticollis as the disease group after refractive error correction and 25 normal children as the control group. A virtual reality system was used to assess and analyze the characteristics of binocular integration by a contrast balance test and binocular stereopsis. Results The 25 children in the disease group included 17 males and 8 females with an average age of 7.5 ± 1.9 years old and an average binocular spherical equivalent of − 0.35 ± 1.46D. The 25 children in the control group were also 17 males and 8 females with an average age of 7.3 ± 2.2 years old and the average binocular spherical equivalent of − 0.48 ± 0.93D. No significant differences were found in the horizontal bar contrast balance test between the 2 groups at near and far distances. Near-distance vertical bar contrast balance test was normal in 23 subjects and suppressed in 2 subjects in the control group, while it was normal in 13 subjects and suppressed in 12 subjects in the disease group, which showed a statistically significant difference (P = 0.002). Far distance vertical bar contrast balance test was normal in 24 subjects and suppressed in 1 subject in the control group, normal in 7 subjects and suppressed in 18 subjects in the disease group, showing a statistically significant difference (P = 0.000). All subjects in the 2 groups showed 100〞 as near distance stereoacuity. At far distance, the mean stereoacuity was 176.00〞 ± 92.56〞 in the control group, and 352.00〞 ± 270.99〞 in the disease group, with a statistically significant difference (P = 0.011). Conclusion By using virtual reality technology, defects in binocular visual function were found in children whose television torticollis persisted after regular refractive error correction. Television torticollis may be associated with the deficit of binocular integration for vertical bars and far distance stereopsis.

The study pertains to the parenting stress, which is believed to be the resultant of child disability and further assesses the needs of the families across selected pockets of Himachal Himalaya. Perceived Stress Questionnaire (PSQ) and Need Assessment Scale were used for the purpose. For assessing the stress level among the parents, PQS was administered among two hundred parents having disabled children, herein called experimental group and two hundred parents with normal children, herein called control group. A three point Need assessment scale was used to measure the needs of 200 families on five different parameters. The result of t-test shows the significant difference between experimental and control groups indicating that the parents of disabled children experience more stress than their control counterpart. The study indicates that people need proper guidance and information regarding a child’s disability, nutritional requirements of a child, vocational training and child management. There is a need for proper counselling for parents suffering from stress and creating consciousness among parents of children with disabilities and in the society.

AbstractThe present study aimed to examine the effects of playing Nintendo Wii games on upper extremity functions compared with conventional physiotherapy, in children with obstetric brachial plexus injury (OBPI). Twenty-two patients with brachial plexus injuries were enrolled. The patients were divided into two groups by simple randomization. The control group (conventional physiotherapy group [CTG]: n = 11) received conventional physiotherapy for 6 weeks (40 minutes per day, for 4 days per week). The study group, called Nintendo Wii group (NWG; n = 11), received conventional physiotherapy as well as tennis, baseball, and boxing games with Nintendo Wii on days when there was no physical therapy. The upper extremity range of motion (ROM) was evaluated using a digital goniometer, motor function was assessed using the Active Movement Scale (AMS), and shoulder functions were assessed with the Mallet Scoring System (MSS). Virtual reality treatment had a positive effect on shoulder flexion, forearm pronation, wrist flexion, ROM, and functionality (p < 0.05). There was a significant improvement in shoulder abduction and shoulder external rotation in the CTG (p < 0.05). There was no significant difference in the MSS values of either groups (p > 0.05). As per the AMS, in the NWG, the shoulder internal rotation increased significantly (p < 0.05). Nintendo Wii treatment used in addition to conventional physiotherapy may be effective in increasing upper extremity functions in children with OBPI. Clinical Trials Number NCT04605601.

Virtual reality (VR), a technology that provides a stimulated sensory experience, has recently been implemented in various fields of medicine. Several studies have investigated the efficacy of VR on preoperative anxiety. The purpose of this meta-analysis was to validate whether VR could relieve preoperative anxiety in patients undergoing surgery. Electronic databases were searched to identify all randomized controlled trials (RCTs) investigating the effect of VR on preoperative anxiety. The primary outcome was defined as the preoperative anxiety scores. We estimated the effect size using the standard mean difference (SMD) with a 95% confidence interval (CI) using a random effect model. Ultimately, 10 RCTs, with a total of 813 patients, were included in the final analysis. Preoperative anxiety was significantly lower in the VR group than in the control group (SMD −0.64, 95% CI −1.08 to −0.20, p = 0.004). In a subgroup analysis, the preoperative anxiety scores were lower in the VR group than in the control group in pediatric patients (SMD −0.71, 95% CI −1.14 to −0.27, p = 0.002), whereas a significant difference was not observed between the two groups in adult patients (p = 0.226). The results of this meta-analysis indicated that VR could decrease preoperative anxiety, especially in pediatric patients.

Abstract Funding Acknowledgements Type of funding sources: None. Background. Nowadays frequently deployed invasive catheter ablation therapy in patients with symptomatic atrial fibrillation (AF) is unfortunately associated with distress such as preoperative anxiety. Improving preoperative patient information may lower anxiety towards AF ablation procedures. Purpose. To evaluate whether a lifelike 360˚ virtual reality (VR) patient information video decreases anxiety levels and improves patient preparation towards AF ablation as compared to standard preoperative patient information. Methods. Consecutive patients planned for AF ablation were recruited from the outpatient AF clinic and were randomized into two groups: the control group and the intervention group (VR group). The control group received standard preoperative information through oral counselling and information leaflets, the VR group received the standard information as well as a short dedicated 360˚ VR video (via in-hospital VR headset and disposable cardboard VR glasses for home use). Online questionnaires (aimed at information provision, anxiety and procedural experience) were administered both pre- and post-ablation. Results. A total of 103 patients (39.8% female, age 64 [58-71] years) were included in the analysis. The VR group (n = 58) reported to be clearly better informed about catheterization laboratory environment (78% vs. 73%) and the course of the procedure (82% vs. 78%), indicated fewer concerns about the procedure (47% vs. 55%) and were eager to learn even more (82% vs. 74%) as compared to controls (n = 45). However, there was no significant difference in the anxiety scores between the VR group and controls (10 [8-12] vs. 10 [8-14], p = 0.548). Home use of the video was satisfactory and resulted in discussion with relatives. Patient overall satisfaction was higher in VR group as compared to controls (84% vs. 81%). Conclusions. This study shows that a dedicated 360˚ VR video reduces concerns but does not reduce anxiety scores. Though, it easily improves procedural knowledge, patient information and patient satisfaction. Especially in times of remote patient care, this new way of informing patients may be of added value.

This study was conducted to observe the effect of atropine in retarding myopia progression and axial length growth in 36 myopic children (atropine group, 24; control, 12). The initial spherical equivalent of the atropine group and control group was -3.0 ± 1.6 dioptre and -3.5 ± 1.6 dioptre respectively. At the 12th month in atropine group, it was -2.9 ± 2.6 dioptre and -4.6 ± 1.9 dioptre in the control group. The power of the atropine group reduced but rose in the control group after 12 months. There was a statistically significant difference in final refractive errors between the two groups (p<0.05). The initial axial length of the atropine group and control group was 24.3± 1.0 mm and 24.6 ± 1.1 mm respectively. In 12th month, the changes in axial length in the two groups was insignificant. However, the mean axial length progression at 12 months of the atropine group was -0.1 ± 0.1 mm and it was lower than the control group which was -0.2 ± 0.2 mm, and this was statistically significant (p<0.05). In conclusion, topical atropine (0.01%) retarded myopia progre-ssion and axial length growth in myopic children.

Background Wayfinding has been adopted in several intense evacuation and navigation simulations; however, the use of biometric measurements for characterizing physiological outcomes has been somewhat overlooked and applied only under limited laboratory conditions. Methods Twenty-four participants took part in a virtual reality (VR) experiment using a wayfinding installation with the Oculus Rift S head-mounted display (HMD). They were immersed in a simulation of a burning underground parking lot and tasked to navigate to the exit. The purpose of this research was to investigate the high-level effect of wayfinding assistive lights on behavioral, physiological, and psychological outcomes. Participants were split into two groups: the control group was exposed to a scene without assistive lights, and the experimental group was exposed to the same scene with assistive lights. Results Results indicate there was no statistically significant difference between the groups in traveled distance, pauses, turns, or game completion time. Curiously, differences between the two groups in heart rate (HR) outcomes were found to be statistically significant, with subjects in the control group displaying an increasing HR trend during simulation. Conclusions This finding, in accordance with previous studies that have shown the efficacy of landmarks and wayfinding affordances in reducing cognitive demands, suggests that assistive lights might contribute to improved brain wiring connectivity during the game. We discuss these findings in the context of a rich wayfinding affordances literature.

Summary Background: This study aimed to investigate the significance of MAMLD1 mutations in the incidence of hypospa-dias in a Chinese population. Methods: The experimental group consisted of 150 domestic children with hypospadias, aged 0.5 to six years and living in different provinces. A total of 120 normal children, aged two to six years, served as the control group. DNA was extracted for the direct sequencing of MAMLD1 genes. Results: Twelve cases (8.0%) of the missense mutation p.N589S were found in the experimental group, whereas four cases (3.0%) of the same mutation were found in the control group. No significant difference was observed in the mutation rate between the two groups (P>0.05). Four cases (2.7%) had a new missense mutation p.P567S in the experimental group, and three cases (2.5%) possessed the same mutation in the control group. No significant difference was observed between the two groups (P>0.05). Conclusions: In this study, the importance of repeated experiments in mutation-related studies was confirmed, which revealed the difference in predisposing genes among different populations. Although the mutation of the MAMLD1 gene had no apparent connection with the incidence of hypospadias in a Chinese population, a new mutation site of the MAMLD1 gene was discovered, which could provide new research topics for future studies.

SUMMARY OBJECTIVE: This study aimed to investigate the effect of virtual reality application on experimental ischemic pain created with a blood pressure instrument in healthy volunteers. METHODS: The research sample consisted of 172 volunteer adult students who conformed to the inclusion criteria. These individuals were assigned into an experimental (n=86) and a control group (n=86) by a simple randomization method. All individuals in the experimental and control groups wereexperimentally subjected to pain for two minutes by applying 260 mmHg of pressure 3-4 cm above the antecubital region of the left arm with an aneroid adult-type blood pressure instrument. During the procedure, the volunteers in the experimental group watched virtual reality images, while those in the control group received no intervention. Immediately after the procedure, the pain levels of the individuals in both groups were assessed with a Visual Analog Scale (VAS). RESULTS: We found that the mean pain score of the individuals in the experimental group was 2.62±1.82, and that of individuals in the control group was 5.75±1.65. Results of the statistical analysis showed a statistically significant difference between the mean pain scores of the individuals in the experimental and control groups (p<0.001). CONCLUSION: This study found that the use of virtual reality was effective in reducing the level of pain in healthy individuals. This method used a smartphone with widespread availability and ease of transportation, which can be used by health professionals as a non-pharmacological method in the management of pain.

Aim. Children with developmental disabilities generally experience more pain than the normal children. Description of pain is generally difficult in children and more so in children with intellectual disabilities. The study aimed at evaluating dental pain in children with intellectual disabilities. Methods. The survey was carried out in an institution caring for intellectually disabled children to determine the oral health status and the treatment needs of the special kids. 236 children were surveyed out of which the test group is comprised of 111 intellectually disabled children and the control group had 125 normal children with age ranging between five to eighteen years. A questionnaire was presented to the caregivers to elaborate about dental pain in their wards using the dental discomfort questionnaire (DDQ+). The children were examined for dental caries and periodontal status based on the WHO indices for oral hygiene status. Result. Results revealed a statistically significant difference between intellectual disability and brushing, chewing, and earache. The frequency of reporting dental pain was lesser in the intellectually disabled group. Conclusion. Children with intellectual disability tended to report dental pain of any nature with lesser frequency than typically developing peers. They also faced greater difficulty in brushing and chewing.

The present study, aimed to evaluate the effects of resistance training (RT) on glycemia, insulinemia, insulin sensitivity, insulin signaling (IS), and tumor necrosis factor-α (TNF-α) levels in rats with periodontitis. 40 male Wistar rats were distributed into 4 groups: sedentary control group (SCN), exercised control group (ExCN), sedentary ligature-induced periodontal disease group (SPD), and exercised ligature-induced periodontal disease group (ExPD). 28 days after inducing periodontitis the RT started (14-week). Glycemia, insulin, TNF-α levels, and insulin sensitivity were analyzed using various methods. IS was evaluated by measuring tyrosine phosphorylated pp185 in insulin-sensitive tissues (western blot method). Higher levels of insulin, HOMA-IR, and TNF-α, and a decrease in insulin sensitivity were observed in the SPD group, which also had decreased levels of insulin-stimulated tyrosine phosphorylated pp185 in muscle and adipose tissue, when compared to the other groups. The ExPD group had increased levels of insulin-stimulated tyrosine phosphorylated pp185 compared to the SPD group, but showed no significant difference when compared to the SCN and ExCN groups. RT reversed both the insulin resistance (IR) and the IS alterations in rats with induced periodontitis, and decreased the insulin and TNF-α levels. Therefore, the results of show the importance of RT in preventing or reversing IR in rats with periodontitis.
