Weighted Blanket Use: A Systematic Review

Effect of weighted blankets on sleep quality among adults with insomnia: a pilot randomized controlled trial

BACKGROUND

Weighted blanket is an emerging non-pharmacotherapy for sleep disorders, but its effect on sleep among relatively healthy adults with insomnia remains uncertain. This study aimed to evaluate whether weighted blankets could better improve sleep quality and sleep-related symptoms among adults with insomnia.

METHODS

In a prospective, pilot randomized controlled trial conducted in three tertiary hospitals in China, participants with clinical insomnia were randomized (1:1) to receive weighted blanket intervention or normal blanket intervention for 1 month by random-number tables. The primary outcomes were sleep quality assessed with Pittsburgh Sleep Quality Index (PSQI) and insomnia severity assessed with Insomnia Severity Index. Subjective outcomes were measured at baseline, 1 week, and 1-month post-intervention. Sleep was also objectively monitored by actigraphy. We did analysis by intention to treat.

RESULTS

A total of 102 participants were randomly assigned to receive weighted blanket intervention (n = 52) or normal blanket intervention (n = 50). 95 (93.1%) participants completed the follow-up, and 7 (6.9%) participants dropped out of the study. The weighted blanket group had significant improvements in sleep quality compared to the normal blanket group after 1 month of intervention (changes in the mean [SD] of PSQI score: -4.1 [4.1] vs. -2.0 [3.2], P = 0.006). Similar results were observed for daytime sleepiness, stress, anxiety, fatigue, and bodily pain (all P < 0.05). Recordings from actigraphy showed a decrease in the mean (SD) of the number of awakenings in weighted blanket group (-1.4 [9.5]) and an increase in normal blanket group (+ 1.0 [7.9]) (P = 0.280). No severe adverse events occurred.

CONCLUSIONS

Weighted blanket might be an effective, safe and promising non-pharmacotherapy tool for improving sleep-related symptoms among adults with insomnia, although validation with a larger sample size is needed.

The effect of weighted blankets on sleep quality and mental health symptoms in people with psychiatric disorders in inpatient and outpatient settings: A systematic review and meta-analysis

There is limited synthesized evidence for weighted blankets usage in psychiatric patients. We performed a PRISMA compliant systematic review and meta-analysis of the effects of weighted blankets on sleep and mental health outcomes in psychiatric patients. MEDLINE, EMBASE, Cochrane Library, and PsycINFO were searched up to December 15th, 2023. Randomized controlled trials (RCT) or cohort studies reporting objective outcome scales of sleep and mental health were included. Standardized mean difference (SMD) measured effect size. Q and I2 tests measured heterogeneity. Cochrane Risk of Bias Tool 2 and NIH Quality Assessment Tool assessed risk of bias. Nine studies of 553 psychiatric inpatients and outpatients with diagnoses including depression, bipolar disorder, ADHD, and autism. 289 participants received weighted blankets and 264 were in control groups. Intervention length ranged from 5 min to one year. Four studies reported evidence for weighted blankets in improving insomnia, total sleep time, and sleep onset latency. Six studies reported evidence for reducing anxiety symptoms. When compared to placebo, those using weighted blankets had improvements to anxiety symptoms (SMD = -0.47, 95% CI: -0.68 to -0.25, p < 0.001). One RCT had low risk of bias, 3 had some concerns, 1 was high risk. Three cohort studies were "fair" and one was "poor" in quality. It was found that weighted blankets can be effective in reducing anxiety in psychiatric patients. However, the literature is limited by heterogeneity of outcome reporting, lack of well designed RCTs, and small sample sizes. Highlighting the need for higher quality studies.

Safety and effectiveness of weighted blankets for symptom management in patients with mental disorders: A systematic review and meta-analysis of randomized controlled trials

BACKGROUND

The current practice guideline regarding treatment for insomnia and sleep disturbances among children and adolescents with autism spectrum disorder (ASD) has been published and it suggests that the use of weighted blankets might not be an evidence-informed practice. However, limited guidance and evidence synthesis exist on the overall effectiveness of a weighted blanket for symptom management among patients with mental disorders, although it has been routinely recommended and prescribed for this population in many mental health care settings.

OBJECTIVE

To systematically evaluate and synthesize existing data on the safety and effectiveness of weighted blankets for symptom management among patients with mental disorders.

METHODS

Comprehensive retrieval of published, unpublished, or ongoing studies was carried out across a series of bibliographic databases, grey literature sources, and clinical trial registry platforms, along with manual screening of the reference lists of the included studies or relevant reviews. Randomized controlled trials (RCTs) were included if they compared a weighted blanket intervention and a control condition among patients with mental disorders. Two reviewers independently extracted the data using a pre-specified form and assessed the methodological quality of the included studies with the revised Cochrane 'Risk of Bias' (RoB 2) tool. Review Manager (RevMan) 5.3 software was used to conduct the meta-analysis when possible. Subgroup and sensitivity analyses, where appropriate, were conducted to explore the robustness of the pooled effect estimates.

RESULTS

Eight studies involving a total of 426 patients were included in this review. Half of the included studies were rated as having a high risk of bias, primarily due to the failure to blind participants for participant-reported measures. No serious adverse events were reported with the application of weighted blankets. The meta-analysis of five studies revealed that the use of weighted blankets induced a small magnitude decrease (standardized mean difference within studies [SMD]= 0.40) in anxiety management. The pooled estimate of three studies reporting the effect of weighted blankets on insomnia revealed a nonsignificant difference between the two groups (mean difference [MD] = -1.92, 95 % confidence interval [CI] = -3.92-0.09, p = 0.06). However, the leave-one-out sensitivity analysis of the two remaining homogeneous studies revealed that patients who used weighted blankets had reduced insomnia severity index (ISI) scores (MD = -2.78, 95 % CI = -4.44 to -1.12, p = 0.001). Additionally, a study without available data for inclusion in the meta-analysis also reported a positive effect in reducing the ISI score. Due to the heterogeneity across studies, summary estimates for the effects of weighted blankets on fatigue and depression were not computed. However, primary studies reporting these two outcomes demonstrated that the application of weighted blankets had a positive effect.

CONCLUSION

Weighted blankets may be a safe and effective add-on treatment for managing common symptoms such as anxiety, insomnia, depression, and fatigue among psychiatric patients. However, these results need to be further confirmed due to the limited number of studies included in this review, the small sample size and the significant heterogeneity across these primary studies. To gain a better understanding of the effect and mechanism of weight blankets, future trials should preferably integrate more objective measures.

A narrative review of research linking non-sexual social touch to sleep quality

This narrative review describes the current state of the literature that has examined associations between non-sexual social touch (i.e., affectionate touch, touch therapies, touch with animals and inanimate objects that mimic social touch) and sleep quality. It also highlights areas for future research to clarify the links and to identify underlying mechanisms. Most existing studies have focussed on and shown positive effects of touch therapies (e.g., massage, therapeutic touch) on sleep quality in clinical populations. Although there are fewer studies examining how other forms of social touch are linked with sleep quality, the existing research provides preliminary evidence supporting affectionate touch (e.g., hugging, skin-to-skin contact) and tactile contact with animals (e.g., dogs) and objects that mimic social touch (e.g., robots, weighted blankets) as predictors of better sleep quality, while touch deprivation and touch aversion are associated with worse sleep quality. Informed by the existing literature, we additionally reviewed potential relational-cognitive (e.g., felt-security) and neurobiological (e.g., oxytocin) mechanisms likely to underlie associations between social touch and sleep quality. Overall, current research supports associations between non-sexual social touch and sleep quality. However, future research is needed to establish these links for specific forms of social touch (and in various populations), to test explanatory mechanisms, and to identify boundary conditions. Understanding associations between non-sexual social touch and sleep quality can inform the development of touch-based interventions to improve sleep quality and health.

Feasibility, acceptability, and perceived effectiveness of weighted blankets during paediatric dental care

BACKGROUND

Weighted blankets are one method to provide deep pressure touch sensations, which are associated with a calming effect on the nervous system. Weighted blankets have been reported to elicit a calming effect during stressful dental encounters and routine prophylactic visits in older adolescents and adults. Preliminary research suggests that weighted blankets are safe and feasible for children in both hospital and home settings; this, however, has not yet been examined in a paediatric dental environment.

AIM

To examine the feasibility, acceptability, and perceived effectiveness of a weighted blanket during paediatric dental care.

DESIGN

This cross-sectional study examined child, caregiver, and dentist-reported responses to survey questions asking about their experience with the weighted blanket during care (n = 20 each per child and caregiver group, n = 9 dentists).

RESULTS

The use of a weighted blanket is feasible, acceptable, and appropriate as reported by caregivers and dentists (means ≥ 4.70 on the Feasibility of Intervention, Acceptability of Intervention, and Intervention Appropriateness Measures). Few problems were described, and all groups overwhelmingly responded with enthusiasm, noted the blanket's potential for future use, and perceived that a weighted blanket improved care (means ≥ 4.10).

CONCLUSIONS

Study findings support the feasibility and acceptability of using a weighted blanket during a routine, noninvasive paediatric dental care.

Do weighted blankets improve sleep among children with a history of maltreatment? A randomized controlled crossover trial

STUDY OBJECTIVES

Sleep disruption is prevalent and persistent among children who experience maltreatment/interpersonal trauma. Weighted blankets have gained popularity in recent years as a potential nonpharmacological intervention for improving sleep in various populations, but their efficacy has not been examined among maltreated children. The current study used a randomized, within-subjects, crossover design to examine whether the use of a weighted blanket improves objective and/or subjective indices of sleep among 30 children, ages 6-15 years (mean = 9.7, standard deviation = 2.9) adopted from foster care.

METHODS

Participants used a weighted blanket for 2 weeks and their usual (unweighted) blanket for 2 weeks in a counterbalanced order. Sleep outcomes were measured using actigraphy and subjective sleep diaries.

RESULTS

No differences in actigraphy-based or subjective estimates of total sleep time, sleep onset latency, wake after sleep onset, or sleep quality ratings were found based on blanket type. Child age, biological sex, timing of participation (school year vs summer months), and maltreatment/trauma history did not impact outcomes.

CONCLUSIONS

Although we did not find evidence that weighted blankets improve sleep among children with a history of maltreatment/interpersonal trauma, additional well-controlled studies using larger samples of children are needed.

Weighted Blankets as a Sleep Intervention: A Scoping Review

IMPORTANCE

Sleep disorders are associated with a range of health conditions, with poor sleep often further exacerbating individuals' health, well-being, and ability to participate in daily occupations. Weighted blankets offer a potentially simple nonpharmacological sleep intervention option.

OBJECTIVE

To summarize available literature on instrumentation and outcomes associated with overnight use of weighted blankets for therapeutic purpose.

EVIDENCE REVIEW

A scoping review following the PRISMA review guidelines was conducted. Sources included MEDLINE, Cochrane Library, CINAHL, PsycINFO, Scopus, Embase, and Google. Included studies reported on overnight use of weighted blankets. Critical appraisal of studies was conducted with standardized tools.

FINDINGS

Eighteen studies met the inclusion criteria. Positive outcomes were reported for adults, including improved sleep, reduction in medication use, and improved mood. Sleep outcomes were mixed for children and adolescents but included improved occupational performance. Methodological quality of included studies regarding effectiveness was variable. Ten studies included details of the intervention, whereas only one study reported on implementation. No specific guidelines for use were included.

CONCLUSIONS AND RELEVANCE

Weighted blankets are used as a sleep intervention for individuals across the life span experiencing a range of health conditions. Currently, there is more evidence of effectiveness with adults, although parents are favorable regarding weighted blanket use for children. Implementation and recommendation of weighted blankets are typically led by occupational therapists, with knowledge of the intervention facilitating use. This review provides information to inform occupational therapists' clinical decision-making and continued implementation of weighted blankets for individuals with sleep problems. Plain-Language Summary: This scoping review summarizes what is known about the use of weighted blankets as a sleep intervention for people of all ages. There is more evidence for overnight use of weighted blankets for adults, with improvements reported in sleep, mood, medication use, and pain. Although there is little evidence of improvement in sleep for children, some children show improvement in everyday functioning, and parents report positive outcomes from overnight use of weighted blankets. These findings suggest that occupational therapists should consider offering or recommending weighted blankets as a sleep intervention option for people of all ages, alongside consideration of individuals' preferences. Development of practice guidelines that incorporate current research findings is urgently needed to support occupational therapists' use of weighted blankets.

Changed sleep according to weighted blanket adherence in a 16-week sleep intervention among children with attention-deficit/hyperactivity disorder

STUDY OBJECTIVES

To examine differences in sample characteristics and longitudinal sleep outcomes according to weighted blanket (WB) adherence.

METHODS

Children with attention-deficit/hyperactivity disorder (n = 94), mean age 9.0 (standard deviation 2.2, range 6-14) participated in a 16-week sleep intervention with WBs. Children were classified as WB adherent (use of WB ≥ 4 nights/wk) or nonadherent (use of WB ≤ 3 nights/wk). Changes in objectively measured sleep by actigraphy, parent-reported sleep problems (Children's Sleep Habits Questionnaire) and child-reported Insomnia Severity Index were evaluated according to adherence with mixed effect models. Sex, age, and attention-deficit/hyperactivity disorder subtype were examined as potential moderators.

RESULTS

Children adherent to WBs (48/94) showed an early response in sleep outcomes and an acceptance of the WB after 4 weeks of use as well as a decrease in parent-reported (Children's Sleep Habits Questionnaire) (-5.73, P = .000) and child-reported (Insomnia Severity Index) (-4.29, P = .005) sleep problems after 16 weeks. The improvement in sleep was larger among WB adherent vs nonadherent (between-group difference: Children's Sleep Habits Questionnaire: -2.09, P = .038; Insomnia Severity Index: -2.58, P = .007). Total sleep time was stable for children adherent to WB but decreased for nonadherent (between-group difference: +16.90, P = .019).

CONCLUSIONS

An early response in sleep and acceptance of the WB predicted later adherence to WBs. Improvements in sleep were more likely among WB adherents vs nonadherents. Children with attention-deficit/hyperactivity disorder may thus benefit from using WBs to handle their sleep problems.

Effect of Weighted Blanket Versus Traditional Practices on Anxiety and Pain in Patients Undergoing Elective Surgery: A Multicenter Randomized Controlled Trial

Perioperative anxiety is common in surgical patients and linked to poor outcomes. This multicenter randomized controlled trial assessed the effect of the use of a warm weighted blanket on presurgical anxiety and pain, as well as postsurgical restlessness, nausea, and vomiting. Levels of anxiety and pain were measured in adult patients using a 100-point visual analog scale before elective surgery. Patients received either a warm weighted blanket (n = 74) or a traditional sheet or nonweighted blanket (n = 74). Patients in the intervention group had significantly lower preoperative anxiety scores (mean [SD] = 26.28 [25.75]) compared to the control group (mean [SD] = 38.73 [30.55], P = .008). However, the intervention had no significant effect on presurgical pain or postsurgical nausea, vomiting, or restlessness. These results suggest that weighted blankets reduce preoperative anxiety in adult patients.

User Experiences of Ball Blankets in Adults with Depression-Related Insomnia: A Qualitative Content Analysis Study

Insomnia is prevalent in patients suffering from depression and may itself exacerbate the disability associated with depression and impede the path to recovery. Although crucial in ensuring meaningful interactions and interventions for patients, research on patients' experiences of depression-related insomnia and its treatment is limited. The purpose of this study was therefore to investigate how adult patients with depression-related insomnia experience sleeping with a weighted Protac Ball Blanket®, focusing on how the blanket feels and works and contributes to their subjective sleep quality experience. An inductive content analysis approach was adopted. Semi-structured interviews were conducted with 13 patients. Four categories were identified: 1) Deep and dynamic touch pressure from the plastic balls induced calmness; 2) Changing sensory impressions from the rolling balls distracted attention from distressing thoughts and emotions; 3) The ball blanket improved the quality and quantity of sleep, which increased daily well-being; 4) Sleeping with the ball blanket was associated with positive as well as negative experiences depending on personal preferences for sensory stimulation. This study explains how the Protac Ball Blanket® as a potential non-pharmacological sleep-intervention improved the sleep of adult patients with depression-related insomnia. The blanket was found meaningful for coping with sleeplessness and with mental and physical unrest.

Passive and low-energy strategies to improve sleep thermal comfort and energy resilience during heat waves and cold snaps

Sleep is a pillar of human health and wellbeing. In high- and middle-income countries, there is a great reliance on heating, ventilation, and air conditioning systems (HVAC) to control the interior thermal environment in the bedroom. However, these systems are expensive to buy, maintain, and operate while being energy and environmentally intensive-problems that may increase due to climate change. Easily-accessible passive and low-energy strategies, such as fans and electrical heated blankets, address these challenges but their comparative effectiveness for providing comfort in sleep environments has not been studied. We used a thermal manikin to experimentally show that many passive and low-energy strategies are highly effective in supplementing or replacing HVAC systems during sleep. Using passive strategies in combination with low-energy strategies that elevate air movement like ceiling or pedestal fans enhances the cooling effect by three times compared to using fans alone. We extrapolated our experimental findings to estimate heating and cooling effects in two historical case studies: the 2015 Pakistan heat wave and the 2021 Texas power crisis. Passive and low-energy strategies reduced sleep-time heat or cold exposure by 69-91%. The low-energy strategies we tested require one to two orders of magnitude less energy than HVAC systems, and the passive strategies require no energy input. These strategies can also help reduce peak load surges and total energy demand in extreme temperature events. This reduces the need for utility load shedding, which can put individuals at risk of hazardous heat or cold exposure. Our results may serve as a starting point for evidence-based public health guidelines on how individuals can sleep better during heat waves and cold snaps without relying on HVAC.

The effect of weighted blankets on sleep and related disorders: a brief review

Background

Sleep disorders such as insomnia can lead to a range of health problems. The high risk of side effects and drug abuse of traditional pharmacotherapy calls for a safer non-pharmacotherapy.

Aims

To examine the use and efficacy of weighted blankets in improving sleep and related disorders in different populations and explore the possible mechanisms.

Methods

A literature search was conducted using PubMed, Embase, Web of Science, MEDLINE, Cochrane Library and CNKI databases. Eligible studies included an intervention with weighted blankets and outcomes covering sleep and/or related disorders (behavioral disturbance, negative emotions and daytime symptoms). Studies using other deep pressure, compression, or exercise-related interventions were excluded.

Conclusions

Most of the included studies showed that weighted blankets could effectively improve sleep quality and alleviate negative emotions and daytime symptoms in patients with sleep disorders, attention deficit hyperactivity disorder, autism spectrum disorder, and other related disorders, with a possible mechanism of deep pressure touch.

Recommendations

Weighted blankets might be a promising tool for sleep interventions among individuals with sleep disorders in clinical settings. More high-quality and large-scale randomized controlled trials are needed to further validate the safety and efficacy of weighted blankets and explore precise mechanisms.

The efficacy of weighted blankets for sleep in children with attention-deficit/hyperactivity disorder-A randomized controlled crossover trial

Weighted blankets are a non-pharmacological intervention for treating sleep and anxiety problems in children with attention-deficit/hyperactivity disorder. However, research on the efficacy of weighted blankets is sparse. The aim of this randomized controlled trial with a crossover design (4 + 4 weeks) was to evaluate the efficacy of weighted blankets on sleep among children with attention-deficit/hyperactivity disorder and sleeping problems. Children diagnosed with uncomplicated Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition attention-deficit/hyperactivity disorder with verified sleep problems were randomized to start with either a weighted blanket or a lighter control blanket. Data collection was performed at weeks 0, 4 and 8 using actigraphy, questionnaires and a daily sleep diary. T-tests were used to evaluate efficacy. The study included 94 children with attention-deficit/hyperactivity disorder (mean age 9.0 [sd 2.2] years; 54 [57.4%] boys). Weighted blankets had a significant effect on total sleep time (mean diff. 7.72 min, p = 0.027, Cohen's d = 0.24), sleep efficiency (mean diff. 0.82%, p = 0.038, Cohen's d = 0.23) and wake after sleep onset (mean diff. -2.79 min, p = 0.015, Cohen's d = -0.27), but not on sleep-onset latency (p = 0.432). According to our exploratory subgroup analyses, weighted blankets may be especially beneficial for improving total sleep time in children aged 11-14 years (Cohen's d = 0.53, p = 0.009) and in children with the inattentive attention-deficit/hyperactivity disorder subtype (Cohen's d = 0.58, p = 0.016). Our results suggest that weighted blankets may improve children's sleep and could be used as an alternative to pharmacological sleep interventions.

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.

A Randomized Cross-over Trial of Behavior Guidance Techniques on Children with Special Needs during Dental Treatment: The Caregivers' Perceived Mannerisms

Aim

To compare caregivers' acceptance, consent, and concern toward utilization of a combination of basic behavior guidance technique (CBBGT) and Papoose Board (PB) for their special needs children and to evaluate the impact of PB usage on the caregiver's attitude and the association between their education level, monthly household income, and previous dental experience.

Materials and Methods

This cross-over study incorporated 90 special needs children who were recruited to receive dental treatment with two ways of behavior guidance exposures consecutively in the order of A-B/B-A design. Exposure A is CBBGT (distraction, tell-show-do, and positive reinforcement), while Exposure B is PB. The dental procedures were either dental prophylaxis or restoration with a handpiece. Caregivers need to answer a paper-based questionnaire before and after exposure. The Wilcoxon sign rank test and logistic regression were utilized in order to establish the comparability, impacts, and association.

Result

About 88 caregivers of special needs children aged between 2 and 15 years completed the sequence. Overall, 98.9% of the children presented with neurodevelopmental disorders. Twenty-seven caregivers were significantly concerned when the combination of basic BGT was applied to their children, and 14 caregivers felt the same for PB. However, the Wilcoxon sign rank test revealed insignificant caregiver scores on acceptance and consent for both methods but significantly improved attitudes towards the use of PB after observing the placement of their children.

Conclusion

The studied caregiver demonstrated equivalent acceptance, consent, and concern toward the use of PB and a combination of basic BGT with improved attitudes after comprehensive explanation and real-time observation of PB usage during their children's dental treatment.

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.

Planning for Change: Co-Designing Implementation Strategies to Improve the Use of Sensory Approaches in an Acute Psychiatric Unit

Implementing sensory approaches in psychiatric units has proven challenging. This multi-staged study involved qualitative interviews (n = 7) with mental health care staff in an acute psychiatric ward to identify the local factors influencing use of sensory approaches, and co-design implementation strategies with key stakeholders to improve their use. Using framework analysis, results revealed that the use of sensory approaches were hindered by: inadequate access to sensory resources/equipment; lack of time; lack of staff knowledge; and belief that sensory approaches are not effective or part of staff's role. To address identified barriers a systematic theory-informed method was used to co-design implementation strategies to improve the use of sensory approaches.

Variation in Twitter posts referencing pediatric sleep aids

OBJECTIVES

Over 50% of parents who use social media seek parenting advice, however little is known about social media discussions surrounding child sleep aid use. The current study investigated Twitter posts about the use of pediatric sleep aids (melatonin, cannabidiol, weighted blankets, and essential oils), including post frequency, user characteristics, and content. In addition, variation in tweets before and after the onset of the COVID-19 pandemic was examined.

METHODS

Twitter was searched over a 25-month period using TweetDeck. Tweets were coded for user characteristics (eg, affiliations, gender) and content (eg, tone, states sleep or health outcomes, reference to a neurodevelopmental condition).

RESULTS

Of the 2754 tweets analyzed, melatonin was referenced most often (60%), followed by essential oils (23%), weighted blankets (14%), and cannabidiol (3%). Most were published by individual users (77%) and were positive (51%) in tone. About 1-third of tweets noted positive sleep or health effects of the sleep aid and only 7% referenced a neurodevelopmental condition. Tweets about pediatric sleep aids increased during the pandemic, primarily those posts about melatonin.

CONCLUSIONS

Melatonin is the most commonly discussed sleep aid on Twitter, followed by essential oils. Tweets are primarily positive. The number of tweets about sleep aids, specifically melatonin, has increased with time, with significantly more tweets after the start of the pandemic. Clinicians should consider using this outlet to provide empirically-based information regarding the efficacy and benefits or risks of sleep aid use in children.

Weighted Blanket Therapy for Periodic Limb Movement Disorder: A Case Report Highlighting Improved Sleep Quality and Reduced Symptoms

This case report describes a 20-year-old female patient with periodic limb movement disorder (PLMD), who experienced trouble sleeping and daytime fatigue. Polysomnography revealed frequent non-arousing periodic limb movements and a high PLMD index. The patient was advised on non-pharmacological interventions, including the use of weighted blankets, sleep hygiene education, and lifestyle modifications. At the six-week follow-up, the patient reported significant improvement in symptoms. The case report highlights the potential effectiveness of non-pharmacological interventions in managing PLMD and emphasizes the need for a multidisciplinary approach to improve patient outcomes and quality of life. Further research is required to determine the long-term efficacy and safety of these interventions. The psychological impact of PLMD on the patient's social life and academic performance is also discussed. The management of sleep disorders should involve a multidisciplinary approach to improve patient outcomes and quality of life.

A weighted blanket increases pre-sleep salivary concentrations of melatonin in young, healthy adults

Weighted blankets have emerged as a potential non-pharmacological intervention to ease conditions such as insomnia and anxiety. Despite a lack of experimental evidence, these alleged effects are frequently attributed to a reduced activity of the endogenous stress systems and an increased release of hormones such as oxytocin and melatonin. Thus, the aim of the present in-laboratory crossover study (26 young and healthy participants, including 15 men and 11 women) was to investigate if using a weighted blanket (~12% of body weight) at bedtime resulted in higher salivary concentrations of melatonin and oxytocin compared with a light blanket (~2.4% of body weight). We also examined possible differences in salivary concentrations of the stress hormone cortisol, salivary alpha-amylase activity (as an indicative metric of sympathetic nervous system activity), subjective sleepiness, and sleep duration. When using a weighted blanket, the 1 hour increase of salivary melatonin from baseline (i.e., 22:00) to lights off (i.e., 23:00) was about 32% higher (p = 0.011). No other significant differences were found between the blanket conditions, including subjective sleepiness and total sleep duration. Our study is the first to suggest that using a weighted blanket may result in a more significant release of melatonin at bedtime. Future studies should investigate whether the stimulatory effect on melatonin secretion is observed on a nightly basis when frequently using a weighted blanket over weeks to months. It remains to be determined whether the observed increase in melatonin may be therapeutically relevant for the previously described effects of the weighted blanket on insomnia and anxiety.

Experiences of Using Weighted Blankets among Children with ADHD and Sleeping Difficulties

Introduction

Sleeping difficulties are common in children with attention deficit hyperactivity disorder (ADHD). A sleep intervention with weighted blankets was designed to increase current understanding of using weighted blankets to target children's individual needs in connection with sleep and daytime functioning.

Aim

To explore how children with ADHD and sleeping difficulties experience the use of weighted blankets.

Methods

An explorative qualitative design in which 26 children with ADHD and sleeping difficulties, 6-15 years old, were interviewed about a sleep intervention with weighted blankets. Four categories emerged from qualitative content analysis.

Results

Children's experiences revealed that the use of weighted blankets 1) requires a commitment, by adjusting according to needs and preferences and adapting to the environment; 2) improves emotional regulation by feeling calm and feeling safe; 3) changes sleeping patterns by creating new routines for sleep and improving sleep quality; and 4) promotes everyday participation by promoting daily function and balancing activity and sleep.

Conclusions

Using weighted blankets promoted children's management of daily life with ADHD and sleeping difficulties. Occupational therapists can improve the assessment and delivery of weighted blankets tailored to individual needs based on increased knowledge from the children themselves.

Weighted Blankets for Pain and Anxiety Relief in Acutely Injured Trauma Patients

To determine the impact of a weighted blanket on acute pain and anxiety in trauma patients, a preliminary prospective/retrospective study at a level-one trauma center (n = 24 patients) was conducted. In this study, 12 patients using weighted blankets for five consecutive days were compared to a matched retrospective cohort of 12 patients not using a blanket. The change in morphine milligram equivalents (MME) and alprazolam milligram equivalents (AME) over five days were compared. There was a significant difference of MME per day between the intervention group (mean MME change = -22.9) and matched controls (mean MME change = 6.2; p = 0.0072) by blanket use. Total MMEs in the intervention group decreased by 275.5 and in the control group increased by 75 between day 1 and day 5. There was no significant difference in AME change between groups (p = 0.3227). The majority of patients who took a post-intervention questionnaire reported less pain and less anxiety with blanket use compared to those without blanket use (78% and 56% of patients, respectively). To summarize, trauma patients in acute pain had less opioid use and reported less pain and anxiety when using a weighted blanket for five consecutive days compared to a control group who did not use a blanket.

Weighted blankets for sleep problems - prescription, use and cost analysis

BACKGROUND

Weighted blankets (WBs) have been suggested as a treatment option for insomnia and are commonly prescribed despite lack of evidence of efficacy.

AIM

To investigate prescription pattern, return rate and cost of WBs.

MATERIAL AND METHODS

This observational cohort register-based study in western Sweden included every individual who, in a 2.5-year period, was prescribed and received at least one WB (n = 4092). A cost evaluation was made by mapping prescription processes for WBs and sleep medication.

RESULTS

Individuals diagnosed with dementia, anxiety, autism or intellectual disability (ID) retained the WB longer than others. Individuals younger than six and older than 65 years had shorter use time. The cost evaluation showed that the prescription process for WBs was longer and resulted in a higher cost than for sleep medication.

CONCLUSIONS

Some individuals had longer use time, indicating a possible benefit from using a WB. Due to low risk of harm but high economic cost, a revision of the WBs prescription process could be recommended to identify those who might benefit from WB.

SIGNIFICANCE

Our result points towards a need for revision of the prescription process, to implement standardized sleep assessments, and create a more efficient prescription process to lower the cost.

Assessing the Impact of Weighted Blankets on Anxiety Among Patients With Anorexia Nervosa and Avoidant- Restrictive Food Intake Disorder: A Randomized Controlled Trial

IMPORTANCE

Interventions to reduce anxiety are needed for patients with anorexia nervosa (AN) and avoidant- restrictive food intake disorder (ARFID). Weighted blankets are one such intervention.

OBJECTIVE

To evaluate the impact of weighted blankets on anxiety for patients with AN and ARFID.

DESIGN

Randomized controlled trial conducted between November 2018 and March 2019. Patients were randomized into the control group or the intervention group.

SETTING

Inpatient setting; medical stabilization unit.

PARTICIPANTS

Patients (N = 23) diagnosed with AN or ARFID and experiencing moderate anxiety. The majority were female (91%), with a mean age of 26 yr (SD = 9.3), and the mean length of hospitalization was 22 days (SD = 17.3).

INTERVENTIONS

Control group participants received usual care, which included occupational therapy services. Intervention group participants received a weighted blanket along with usual care.

OUTCOMES AND MEASURES

Mixed-effects regression models were conducted. Primary outcomes included improvement in Beck Anxiety Inventory (BAI) scores by discharge.

RESULTS

Intervention group patients had a greater, non-statistically significant decrease in BAI score over time (B = 1.16, p = .83) than control group patients.

CONCLUSIONS AND RELEVANCE

Weighted blankets may be an effective tool for reducing anxiety among patients with AN or ARFID. What This Article Adds: The use of a weighted blanket, in conjunction with occupational therapy interventions, is potentially a beneficial non-pharmacological option for patients with anorexia nervosa (AN) and avoidant-restrictive food intake disorder (ARFID). The current study adds an additional modality to the multidisciplinary treatment approach for eating disorders.

Weighted Blankets' Effect on the Health of Older People Living in Nursing Homes

Background: An increasingly aging population is a global phenomenon. While considered a positive step forward, vulnerability to age-related health problems increases along with the ageing population. The aim of the study was to investigate weighted blankets’ effect on health regarding quality of life (QoL), sleep, nutrition, cognition, activities of daily living ADL and medication in older people living in nursing homes. Methods: In total, 110 older people were involved in an intervention with weighted blankets, and 68 older people completed the intervention. Measures before and after were performed regarding quality of life; QoL-AD, EQ-VAS, sleep; MISS, nutrition; MNA, cognition; S -MMSE (ADL) and medication. Comparative statistical analyses were applied. Results: After intervention with weighted blankets, health in general, such as QoL, improved. Sleep also improved significantly, especially with respect to waking up during the night. Nutrition was enhanced, health as a cognitive ability improved, and medication in the psychoanaleptic group decreased. The effect size varied between small and large. Conclusions: A weighted blanket seems to be an effective and safe intervention for older people in nursing homes, as several improvements were made regarding the health of older people.

Feasibility and Acceptability of a Remotely Delivered Weighted Blanket Intervention for People Living With Dementia and Their Family Caregivers

The COVID-19 pandemic amplified the need for interventions to support community-dwelling families living with dementia. This study examined the feasibility and acceptability of a remotely delivered weighted blanket intervention for people living with dementia, and the feasibility of collecting outcome measures specific to people with dementia and caregivers. A prospective, within subjects, pre-post design was used; 21 people with dementia and their caregivers participated. Measures of feasibility (days blanket was used for the recommended duration, injuries/adverse events, enrollment, and withdrawal rate, time to recruit sample) and acceptability (tolerability, satisfaction, and benefit perceived by participants with dementia and caregivers) were examined. Feasibility of collecting measures was examined through missing data. Results indicated high feasibility and acceptability. Collecting caregiver completed outcome measures was feasible, but measures completed by self-report by people with dementia was not. Weighted blankets are a promising tool for this population that warrant further examination to determine efficacy.

A realist evaluation of weighted modalities as an alternative to pro re nata medication for mental health inpatients

Implementing psychosocial approaches into mental health inpatient settings continues to be challenging. This is despite mental health policies prioritizing trauma-informed and recovery-orientated care approaches. This study reports on an interdisciplinary project that implemented and examined the uptake of weighted modalities in a psychiatric inpatient rehabilitation setting. While over-reliance on pro re nata (PRN) medication in these settings has been reported, weighted modalities are a sensory approach that can be self-initiated by consumers as an alternative to use of PRN to manage distress and agitation. A mixed-methods realist approach was used to determine what works, for whom, and in what circumstances weighted modalities were offered by clinicians and used by consumers. Additionally, we were interested in determining whether there was an associated change in PRN use during the trial. Data included in-depth interviews with consumers (n = 12) and clinicians (n = 11), and extraction of PRN medication use preceding, throughout, and following implementation. Statistical analysis revealed a significant increase in PRN rates in the first 3 months of implementation (mean difference from baseline = 29.5, P = 0.047) but a significant decrease in the second three-month period following implementation (mean difference from baseline = -30.7, P = 0.036). Qualitative findings highlighted the key components of successful implementation as being environmental restructuring (availability/accessibility and visibility of weighted modalities) and social influences. Strategies to enhance these components are discussed.

SLEEP: intervention with weighted blankets for children with attention deficit hyperactivity disorder (ADHD) and sleep problems: study protocol for a randomised control trial

INTRODUCTION AND OBJECTIVES

Children with attention deficit hyperactivity disorder (ADHD) have an increased risk of sleep problems. Weighted blankets are one possible non-pharmacological intervention for these problems in this group of children. However, the effectiveness of weighted blankets is insufficiently investigated. This study aims to investigate the effectiveness of weighted blankets in terms of sleep, health-related outcomes and cost-effectiveness as well as to explore children's and parents' experiences of a sleep intervention with weighted blankets.

METHODS AND ANALYSIS

This study is a randomised placebo-controlled crossover trial comparing the effect of weighted fibre blankets (active) with fibre blankets without weight (control). Children aged 6-13 years, recently diagnosed with uncomplicated ADHD with verified sleep problems, were included in the study. The study period is 4 weeks for each condition, respectively, and then an 8-week follow-up. A total of 100 children diagnosed with ADHD and sleep problems will enter the study. The primary outcomes are sleep and cost per quality-adjusted life years. The secondary outcomes are health-related quality of life, ADHD symptoms, psychological distress and anxiety. Interviews with a subsample of the participating children and parents will be conducted for exploring the experiences of the intervention.

ETHICS AND DISSEMINATION

Ethical approval of the trial has been obtained from the Swedish Ethical Review Authority (number 2019--2158) and conforms to the principles outlined in the Declaration of Helsinki (WMA, 2013). Results will be reported as presentations at peer-review conferences, in articles in peer-review journals and meetings with healthcare providers.

Weighted blanket and sleep medication use among adults with psychiatric diagnosis - a population-based register study

OBJECTIVE

To measure rate of subscription of common sleep medication and diagnoses of substance use disorder (SUD) before and after receiving a prescribed weighted blanket (WB) among patients with psychiatric diagnoses.

MATERIALS AND METHODS

Using register-based data of health-related factors in a Swedish region, a total of 1785 adult individuals with a psychiatric diagnosis, received a WB and resided in the region during the study period were identified. Using each individual as their own control, the rate of one-year prior prescription of WB or diagnosed SUD was compared to rate after a half year wash-out after prescription of WB for a full year.

RESULTS

The number of patients without prescription of sleep medication increased by 3.3% (95% confidence interval (95%CI): 0.2-6.4, p=.04). Furthermore, the proportion without a prescription of benzodiazepine receptor agonist/antihistamines sleep medication increased by 5.5% (95%CI: 2.2-8.8, p=.001). Melatonin prescription increased after WB by 3.6% (95%CI: 1.1-6.2, p=.006). Younger age and unipolar-, anxiety-, attention-deficit/hyperactivity-, and post-traumatic stress disorder was associated with decreased use while psychotic-/bipolar- and personality disorder was not associated with a decrease in the use of sleep medication. The number of alcohol SUD diagnoses did not increase while sedative SUD rate increased statistically significantly by 0.7% (odds ratio = 1.63, p=.02). In a multivariate model, only younger age predicted discontinuation of sleep medication while psychotic-/bipolar- and personality disorder had statistically less decrease.

CONCLUSION

This observational register study found a statistically significant association between WB use and decreased use of common sleep medication except melatonin that increased slightly.

Feasibility trial of weighted blankets as an intervention for emergence delirium in postoperative pediatric patients

BACKGROUND

Emergence delirium (ED) is a significant problem in the post anesthesia care unit (PACU), resulting in dislodgement of medical devices, patient and staff injury, prolonged recovery, and parent dissatisfaction. Parental requests for the use of weighted blankets in the hospital setting have increased. However, while weighted blankets have shown potential as treatment for anxiety in adults and children, no studies have demonstrated their safe use with children in the hospital setting.

PURPOSE

To explore the safety of weighted blanket use with children in the PACU as an intervention for ED, a feasibility study was conducted.

DESIGN AND METHODOLOGY

A convenience sample of 93 participants, aged three to 10 years were recruited. Watcha scores, vital signs, length of wear time, and reason for blanket removal were recorded for all patients.

RESULTS

Eighty-five patients completed the study. Four participants experienced vital signs outside the defined safety parameters, with only one experiencing an adverse event (1.2%). This was consistent with the historic adverse event rate of 1% for the study site. Staff did not report issues with the use or cleaning of the blankets. Of interest, there was significant correlation between ED and suspected pain.

CONCLUSION

The study demonstrated weighted blanket use is safe and feasible with children in the hospital setting, Additional studies are needed to determine the effectiveness of weighted blankets as an intervention for ED and the impact pain may have on the severity and prevalence of ED.

Parents' Experiences of Weighted Blankets' Impact on Children with Attention-Deficit/Hyperactivity Disorder (ADHD) and Sleep Problems-A Qualitative Study

Sleep disturbances are common among children with attention-deficit/hyperactivity disorder (ADHD). While pharmacological treatment has increased dramatically, parents often prefer non-pharmacological interventions. Research on experiences of weighted blankets and their effect in sleep improvement is scarce. The aim of this study was to explore parents' experiences of weighted blankets for children with ADHD and sleep problems, and the impact on their children's sleep. The explorative design was based on qualitative content analysis. Interviews were conducted with a purposeful sample of 24 parents of children with ADHD and sleep problems, after completing a sleep intervention with weighted blankets for 16 weeks. Parents reported that children sleeping with weighted blankets: (1) achieved satisfactory sleep, including improved sleep onset latency, sleep continuity, and sleep routines; (2) achieved overall well-being, including improved relaxation and reduced anxiety; and (3) mastered everyday life, including improved balance in life, family function, and participation in school and leisure activities. This study brings forward novel aspects of the effects of improved sleep among children with ADHD. The findings contribute to the understanding of potential positive effects of an intervention with weighted blankets critical for clinical practice to improve sleep, well-being, and everyday life of children with ADHD and their families.

A randomized controlled study of weighted chain blankets for insomnia in psychiatric disorders

STUDY OBJECTIVES

This study aimed to evaluate the effect of weighted chain blankets on insomnia and sleep-related daytime symptoms for patients with major depressive disorder, bipolar disorder, generalized anxiety disorder, and attention deficit hyperactivity disorder.

METHODS

One hundred twenty patients were randomized (1:1) to either a weighted metal chain blanket or a light plastic chain blanket for 4 weeks. The outcome was evaluated using the Insomnia Severity Index as primary outcome measure and day and night diaries, Fatigue Symptom Inventory, and Hospital Anxiety and Depression Scale as secondary outcome measures. Sleep and daytime activity levels were evaluated by wrist actigraphy.

RESULTS

At 4 weeks, there was a significant advantage in Insomnia Severity Index ratings of the weighted blanket intervention over the light blanket (P < .001) with a large effect size (Cohen's d 1.90). The intervention by the weighted blanket resulted in a significantly better sleep-maintenance, a higher daytime activity level, and reduced daytime symptoms of fatigue, depression, and anxiety. No serious adverse events occurred. During a 12-month open follow-up phase of the study, participants continuing to use weighted blankets maintained the effect on sleep, while patients switching from a light to a weighted blanket experienced an effect on Insomnia Severity Index ratings similar to that of participants using the weighted blanket from the beginning.

CONCLUSIONS

Weighted chain blankets are an effective and safe intervention for insomnia in patients with major depressive disorder, bipolar disorder, generalized anxiety disorder, or attention deficit hyperactivity disorder, also improving daytime symptoms and levels of activity.

Weighted Blankets and Sleep Quality in Children with Autism Spectrum Disorders: A Single-Subject Design

The purpose of the study was to explore the efficacy of weighted blanket applications and sleep quality in children with autism spectrum disorder and behavioral manifestations of sensory processing deficits. Two 4-year-old participants diagnosed with autism spectrum disorder who also experienced sleep disturbances took part in a single-subject design study. Objective sleep measures and caregiver surveys were tracked for a baseline period of eight days, followed by a 14-day weighted blanket intervention and a seven-day withdrawal phase. Caregiver reports and objective data were evaluated using visual analysis and the percentage of non-overlapping data methods. The results suggest minimal changes in sleep patterns as a result of the weighted blanket intervention. The findings based on using a weighted blanket intervention were enhanced morning mood after night use and a significantly decreased time to fall asleep for participants, though they were not strong enough to recommend for clinical use. Future directions include single-subject and cohort-designed studies exploring the efficacy of weighted blankets with increasing sleep quality among children with autism.
