Effects of Weighted Vests on Attention, Impulse Control, and On-Task Behavior in Children With Attention Deficit Hyperactivity Disorder

The Impact of Weighted Blanket Use on Adults with Sensory Sensitivity and Insomnia

Purpose

This study's purpose was to determine the impact of weighted blanket use on moderate to severe insomnia in adults with sensory sensitivity greater than the average population.

Methods

For this study, a four-week, single-case, multiple-participant ABA study design was used. Through convenience sampling, four participants scoring 15 or greater on the Insomnia Severity Index (ISI), which categorizes them as having moderate to severe insomnia, and much more than most people in sensory sensitivity on the Adolescent/Adult Sensory Profile were recruited. First, seven-day baseline sleep data was gathered, followed by two weeks of weighted blanket use, concluding with a seven-day withdrawal phase. Additional outcome measures included: Tuck and Snooze Survey, Consensus Sleep Diary Morning, and Additional Sleep Diary Questions. Data analysis included visual analysis, mean comparisons, Tau-U calculations, and pre- to post-ISI category comparisons.

Results

All participants' ISI scores were categorized as one level less severe postintervention. All participants demonstrated increased sleep quality, and three participants showed an increase in sleep duration based on individual mean comparisons between baseline and intervention phases.

Conclusion

Weighted blankets appear beneficial in reducing insomnia severity in adults with much more than the average population sensory sensitivity. In addition, those with self-reported anxiety may have increased benefit from this intervention.

Teachers' and Parents' Assessment of Challenges in Children Exhibiting Sensory Seeking Behavior and Possible Effects of the Use of Ball Vests: A Pre-Post Study

Children with dysfunction in sensory processing (DSP) may experience challenges, which might affect their participation in activities and potentially also their further development. This study examined the challenges of children with DSP who exhibit sensory seeking behavior, the differences in these challenges between boys and girls, and the possible effects of their use of ball vests. The challenges of 70 pupils (aged 6-12 years) exhibiting sensory seeking behavior were assessed by their parents (n = 66) and teachers (n = 60) by surveys containing items from the 'Strengths and Difficulties Questionnaire' (SDQ) and the 'Five to Fifteen' (FTF) questionnaire. Differences in the SDQ/FTF scores between boys and girls were explored using chi-square analysis. The potential effects of the ball vest were assessed using a study-specific follow-up survey. Linear mixed model regression analysis was used to examine associations between the extent of use of the vest and the assessed effects. The pupils were assessed for challenges that interfered with their learning (62%), forming friendships (51.7%), and the classroom environment (56.9%). After three weeks, the parents found that some pupils had improved regarding attention (39%), body perception (34%), and hyperactivity and impulsivity (33%). The teachers reported that 30% of the pupils had improved their coping skills in learning.

The effectiveness of weighted blankets on sleep and everyday activities - A retrospective follow-up study of children and adults with attention deficit hyperactivity disorder and/or autism spectrum disorder

BACKGROUND

Attention deficit hyperactivity disorder (ADHD) and Autism Spectrum Disorder (ASD) are often accompanied by sleep problems influencing social, emotional and cognitive functioning in everyday activities.

AIM

The aim of this study was to investigate whether the use of a weighted blanket has a positive impact on sleep and everyday activities in individuals with ADHD and/or ASD.

MATERIAL AND METHODS

The study included 85 individuals diagnosed with ADHD and/or ASD, 48 children aged ≤17 (57%) and 37 adults ≥18 years (44%), who were prescribed with a weighted blanket. The participants responded via a telephone interview.

RESULTS

Findings demonstrated that a weighted blanket improved abilities related to falling asleep, sleeping the whole night, and relaxing during the day. Using a weighted blanket improved morning/evening daily routine, including preparing/going to sleep and waking up in the morning.

CONCLUSIONS

Weighted blankets showed positive impact on falling asleep, sleeping the whole night, and relaxing during the day, and they were used frequently by children and adults with ADHD and/or ASD. Findings indicate that a weighted blanket improved morning/evening routine, however this research area needs further investigation using both subjective and objective parameters.

Deep Pressure Therapy: A Promising Anxiety Treatment for Individuals With High Touch Comfort?

One method for managing anxiety, a highly prevalent modern mental health condition, is the calming touch sensations of deep pressure therapy (DPT). Solutions for administering DPT include the Automatic Inflatable DPT (AID) Vest, which we designed in past work. Although benefits of DPT are clear in a subset of the related literature, these benefits are not ubiquitous. There is limited understanding of what factors lead to DPT success for a given user. In this work, we present the findings of a user study ( N = 25) that evaluates the effects of the AID Vest on anxiety. We compared physiological and self-reported measures of anxiety across Active (inflating) and Control (inactive) states of the AID Vest. In addition, we considered the presence of placebo effects and assessed participant comfort with social touch as a potential moderator. The results support our ability to reliably induce anxiety, and show that the Active AID Vest tended to reduce biosignals related to anxiety. We also found a significant relationship between comfort with social touch and reductions in self-reported state anxiety for the Active condition. Those who seek to successfully deploy DPT can benefit from this work.

Preliminary inter-rater reliability of “The observed Off-task Behavior among School-Children” (The OBS-Children)

This study investigated the inter-rater reliability of The observed Off-task Behavior among School Children (The OBS-Children), developed to measure observed off-task behavior among children from 6 to 12 years old with sensory processing difficulties and sensory seeking behavior. Two raters rated 18 videos of 10 children in a controlled school-like setting. Inter-rater reliability was calculated using Intraclass Correlation Coefficients (ICCs 2.1). Standard Error of Measurement (SEM) and Limits of Agreement (LoA) were calculated as a parameter of measurement error. Four out of six items had good to excellent reliability (ICC 0.83–0.95), while one had moderate reliability (ICC 0.75) and one had poor reliability (ICC 0.28). SEM was mostly small, while LoA ranged quite widely on all but one item. The reliability of the OBS-Children can be considered acceptable except from two problematic items. Measurement error was relatively large for all items, implying a need for further development and psychometric testing of the tool.

Efficacy of Sensory Interventions on School Participation of Children With Sensory Disorders: A Systematic Review

Research demonstrates lower school participation in children with sensory disorders. However, the scientific body of evidence supporting existing sensory intervention modalities is difficult to tackle. More specifically, the literature appears poorly organized, with a highly variable terminology, often with nonoverlapping definitions and lack of good keywords classification that would help organize the diversity of approaches. This systematic review organizes the body of evidence for 3 specific approaches (sensory based, sensorimotor, and sensory integration) and questions their efficacy in improving school participation for children with sensory disorders. Two methods were compared: first, a standard systematic review of the literature in 3 databases using appropriate keywords and descriptors, then an original method based on forward and backward citation connections. A total of 28 studies were retrieved, of which only 7 used the standard method for systematic reviews. For sensory-based approaches, the efficacy of weighted-vest varies according to different factors such as the protocol of use. For sensorimotor approaches, the efficacy of therapy balls, air cushions, platform swing, and physical exercise varies according to the child's sensory characteristics. The efficacy of the sensory integration approach remains mixed across studies.

High-risk follow-up: Early intervention and rehabilitation

Early detection of childhood disability is possible using clinically available tools and procedures. Early detection of disability enables early intervention that maximizes the child's outcome, prevents the onset of complications, and supports parents. In this chapter, first we summarize the best-available tools for accurately predicting major childhood disabilities early, including autism spectrum disorder, cerebral palsy, developmental coordination disorder, fetal alcohol spectrum disorder, intellectual disability, hearing impairment, and visual impairment. Second, we provide an overview of the preclinical and clinical evidence for inducing neuroplasticity following brain injury. Third, we describe and appraise the evidence base for: (a) training-based interventions that induce neuroplasticity, (b) rehabilitation interventions not focused on inducing neuroplasticity, (c) complementary and alternative interventions, (d) environmental enrichment interventions in the neonatal intensive care and community settings, and (e) parent-child interaction interventions in the neonatal intensive care and community settings. Fourth, we explore emergent treatment options at clinical trial, designed to induce brain repair following injury. In conclusion, early diagnosis enables early intervention, which improves child and parent outcomes. We now know which interventions provide the biggest gains and the information can be used to help inform parental decision making when designing treatment plans for their children.

Specific Sensory Techniques and Sensory Environmental Modifications for Children and Youth With Sensory Integration Difficulties: A Systematic Review

This systematic review examined the effectiveness of specific sensory techniques and sensory environmental modifications to improve participation of children with sensory integration (SI) difficulties. Abstracts of 11,436 articles published between January 2007 and May 2015 were examined. Studies were included if designs reflected high levels of evidence, participants demonstrated SI difficulties, and outcome measures addressed function or participation. Eight studies met inclusion criteria. Seven studies evaluated effects of specific sensory techniques for children with autism spectrum disorder (ASD) or attention deficit hyperactivity disorder: Qigong massage, weighted vests, slow swinging, and incorporation of multisensory activities into preschool routines. One study of sensory environmental modifications examined adaptations to a dental clinic for children with ASD. Strong evidence supported Qigong massage, moderate evidence supported sensory modifications to the dental care environment, and limited evidence supported weighted vests. The evidence is insufficient to draw conclusions regarding slow linear swinging and incorporation of multisensory activities into preschool settings.

Effectiveness of a Sensory-Enriched Early Intervention Group Program for Children With Developmental Disabilities

OBJECTIVE. The study’s objective was to evaluate the effectiveness of the Interdisciplinary Sensory-Enriched Early Intervention (ISEEI) group program for children with developmental delays.

METHOD. We conducted a retrospective chart review of 63 children ages 18–36 mo who participated in ISEEI. We evaluated participants with the Bayley Scales of Infant and Toddler Development III (Bayley–III) and the Infant/Toddler Sensory Profile (ITSP) at enrollment and after 3–9 mo. We conducted a paired t test to examine changes in the Bayley–III between pre- and posttests.

RESULTS. At enrollment, 70% of children presented atypical scores in two or more areas of sensory processing in the ITSP. Results revealed that children with sensory processing difficulties demonstrated significant improvement in all areas of development except fine motor skills; children without sensory processing difficulties showed significant improvement in language and cognition.

CONCLUSION. The ISEEI group program is an effective method to ameliorate developmental delays.

Effects of deep pressure stimulation on physiological arousal

Deep pressure stimulation has been used in therapeutic practice because of the assumption that it changes physiological arousal. The purpose of this study was to test the effects of deep pressure stimulation, applied with a Vayu Vest (Therapeutic Systems), on both autonomic arousal and performance in a normative adult sample. A repeated-measures, repeated-baseline design was used with participants completing a performance test before and after deep pressure application. A convenience sample of 50 adults participated in the study. Results showed that wearing the Vayu Vest for even short periods of time reduced sympathetic arousal and non-stimulus-driven electrical occurrences. Concomitant increases in parasympathetic arousal were found. Performance improvements were noted after wearing the Vayu Vest, potentially because of changes in arousal. We conclude that deep pressure stimulation is capable of eliciting changes in autonomic arousal and may be a useful modality in diagnostic groups seen by occupational therapy practitioners.

Effects of therapeutic climbing activities wearing a weighted vest on a child with attention deficit hyperactivity disorder: a case study

[Purpose] The purpose of this study was to evaluate the effect of therapeutic climbing activities on the brain waves and attention of a child with attention deficit hyperactivity disorder. [Subject and Methods] The subject of this case study was a 7 year 6-month old child diagnosed with attention deficit hyperactivity disorder. This study was based on evidence gathered at 3 distinct stages: a pre-intervention period, 10 intervention periods (2 weeks), and one post-intervention period. The intervention involved therapeutic climbing activities wearing a weighted vest over the course of 4 weeks. The clinical outcome measures were electroencephalography and the Star Cancellation Test. [Results] The mean activation of alpha waves was improved by the therapeutic intervention. During the intervention, the mean activation of alpha waves was the highest at the F3 cortical locus and the lowest at the T4 cortical locus. The average Star Cancellation Test scores were 43 at pre-intervention, 50 during the therapeutic intervention, and 52 at post-intervention. The performance time of the Star Cancellation Test was 240.1 seconds at pre-intervention, 90.2 seconds during the therapeutic intervention, and 60.0 seconds at post-intervention. [Conclusion] The results of this study suggest that therapeutic climbing activities performed wearing a weighted vest had positive effects on the brain waves and the attention span of a child with attention deficit hyperactivity disorder.
