Parasympathetic effect of deep pressure input on third molar extraction in adolescents

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 routine, noninvasive paediatric dental care.

Effect of deep pressure input on autonomic regulation during wisdom tooth extraction: From waiting room to surgery

Background and purpose

Tooth extraction is a common dental procedure associated with heightened anxiety, particularly during the waiting period before treatment. This stress response is regulated by the autonomic nervous system (ANS), comprising the sympathetic nervous system (SNS), which induces excitatory responses, and the parasympathetic nervous system (PsNS), which promotes relaxation. Deep pressure input, delivered through weighted vests and blankets, has been shown to shift ANS dominance from the SNS to the PsNS, facilitating stress reduction. This study investigated the effects of deep pressure input on ANS modulation using a weighted vest during the waiting phase and a weighted blanket during the tooth extraction phase.

Materials and methods

Healthy adults were randomly assigned to a control group or an experimental group. The control-group subjects underwent wisdom tooth extraction without deep pressure input, while the experimental-group subjects wore a weighted vest during the waiting phase and used a weighted blanket during the tooth extraction procedure. Heart rate (HR), low-frequency heart rate variability (LF-HRV), and high-frequency heart rate variability (HF-HRV) were measured to assess ANS activity.

Results

The control-group subjects exhibited increased HR, elevated LF-HRV, and reduced HF-HRV, indicating the stress-induced sympathetic activation. In contrast, the experimental-group subjects showed significantly lower HR and higher HF-HRV, demonstrating the enhanced parasympathetic activation that persists throughout the tooth extraction procedure.

Conclusion

Deep pressure input for high-anxiety patients can effectively reduce stress and enhances the parasympathetic activation during the wisdom tooth extraction procedure. After a large-scale clinical study, it may enter clinical application for high-anxiety patients.

Comfort evaluation and physiological effects/autonomic nervous system response of inflatable deep pressure vest in reducing anxiety

Background

Deep pressure therapy treats anxiety by triggering physiological responses and promoting calmness. Moreover, measuring user comfort can improve product quality.

Objective

To investigate the physiological effects and subjective comfort level of inflatable deep pressure vests to enhance their calming effect.

Methods

Experimental research was conducted with a one-group pretest-posttest design for physiological effects using pulse oximetry for peripheral pulse rate and a one-shot case study for three subscale parameters that help evaluate comfort (pressure, touch, and mobility) using the Numerical Rating Scale (NRS). Deep pressure intervention using the Inflatable Vest was performed for three sessions, each lasting 5 min.

Results

This study was conducted with 46 participants (24 males, 22 females) aged 17-20 (19.52 ± 0.78). Although pulse rate consistently decreased in all sessions, session 1 showed a significant decrease (p = 0.014*, d = 0.379), whereas sessions 2 (p = 0.274, d = 0.163) and 3 (p = 0.597, d = 0.078) demonstrated non-significant decreases with small effect sizes. The pressure comfort subscale showed that 87.0 %, 4.3 %, and 8.7 % of the participants, and the touch comfort subscale test revealed that 82.6 %, 8.7 %, and 73.9 % of the participants rated it as comfortable, very comfortable, and less comfortable, respectively. The mobility subscale test showed that 73.9 % of the participants rated no limitation, 17.4 % rated somewhat limited, and only 8.7 % rated limitation. Decreased pulse rate and pressure comfort were significantly positively correlated (r = 0.282**, p < 0.01), whereas touch pressure and mobility were not (r = 0.160, p > 0.05; and r = 0.121, p > 0.05, respectively). Decreased pulse rate was also positively correlated with the overall score for the three aspects (r = 0.201*, p < 0.05).

Conclusions

A comfortable inflatable deep pressure vest provides a physiologically calming effect for therapeutic modalities.

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.

The change of attention network functions and physiological adaptation during high-altitude hypoxia and reoxygenation

Previous studies have not reached a definitive conclusion regarding the effect of high-altitude hypoxia and reoxygenation on attention. To clarify the influence of altitude and exposure time on attention and the relations between physiological activity and attention, we conducted a longitudinal study to track attention network functions in 26 college students. The scores on the attention network test and physiological data, including heart rate, percutaneous arterial oxygen saturation (SpO2), blood pressure, and vital capacity in pulmonary function measurement, were collected at five time-points: two weeks before arriving at high altitude (baseline), within 3 days after arriving at high altitude (HA3), 21 days after arriving at high altitude (HA21), 7 days after returning to sea level (POST7) and 30 days after returning to sea level (POST30). The alerting scores at POST30 were significantly higher than those at baseline, HA3 and HA21; the orienting scores at HA3 were lower than those at POST7 and POST30; the executive control scores at POST7 were significantly lower than those at baseline, HA3, HA21, and POST30; and the executive control scores at HA3 were significantly higher than those at POST30. The change in SpO2 during high-altitude acclimatization (from HA3 to HA21) was positively correlated with the orienting score at HA21. Vital capacity changes during acute deacclimatization positively correlated with orienting scores at POST7. Attention network functions at the behavioral level did not decline after acute hypoxia exposure compared with baseline. Attention network functions after returning to sea level were improved compared with those during acute hypoxia; additionally, alerting and executive function scores were improved compared with those at baseline. Thus, the speed of physiological adaptation could facilitate the recovery of orienting function during acclimatization and deacclimatization.

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' 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.

Physiological Effect of Deep Pressure in Reducing Anxiety of Children with ASD during Traveling: A Public Transportation Setting

Traveling with children with autism can be very challenging for parents due to their reactions to sensory stimuli resulting in behavioral problems, which lead to self-injury and danger for themselves and others. Deep pressure was reported to have a calming effect on people with autism. This study was designed to investigate the physiological effect of deep pressure, which is an autism hug machine portable seat (AHMPS) in children with autism spectrum disorders (ASD) in public transportation settings. The study was conducted with 20 children with ASD (16 boys and 4 girls) at the Semarang Public Special School with an age ranging from 4 to 13 years (mean 10.9 ± 2.26 years), who were randomly assigned into two groups. The experiment consisted of group I who used the AHMPS inflatable wraps model and group II who used the AHMPS manual pull model. Heart rate (HR) and skin conductance (SC) were analyzed to measure the physiological calming effect using pulse oximeter oximetry and a galvanic skin response (GSR) sensor. Heart rate was significantly decreased during the treatment compared to the baseline (pre-test) session in group I (inflating wrap model) with p = 0.019, while no change of heart rate variability (HRV) was found in group II (manual pull model) with p = 0.111. There was no remaining effect of deep pressure using the HRV indicator after the treatment in both groups (group I with p = 0.159 and group II with p = 0.566). GSR captured the significant decrease in skin conductance during the treatment with p < 0.0001 in group I, but no significant decrease was recorded in group II with p = 0.062. A skin conductance indicator captured the remaining effect of deep pressure (after the treatment); it was better in group I (p = 0.003) than in group II (p = 0.773). In conclusion, the deep pressure of the AHMPS inflating wrap decreases physiological arousal in children with ASD during traveling.

The Relationship between Dental Fear and Anxiety, General Anxiety/Fear, Sensory Over-Responsivity, and Oral Health Behaviors and Outcomes: A Conceptual Model

Dental fear and anxiety (DFA) is common across the lifespan and represents a barrier to proper oral health behaviors and outcomes. The aim of this study is to present a conceptual model of the relationships between DFA, general anxiety/fear, sensory over-responsivity (SOR), and/or oral health behaviors and outcomes. Two rounds of literature searches were performed using the PubMed database. Included articles examined DFA, general anxiety/fear, SOR, catastrophizing, and/or oral health behaviors and outcomes in typically developing populations across the lifespan. The relationships between the constructs were recorded and organized into a conceptual model. A total of 188 articles were included. The results provided supporting evidence for relationships between DFA and all other constructs included in the model (general anxiety/fear, SOR, poor oral health, irregular dental attendance, dental behavior management problems [DBMP], and need for treatment with pharmacological methods). Additionally, SOR was associated with general anxiety/fear and DBMP; general anxiety/fear was linked to poor oral health, irregular attendance, and DBMP. This model provides a comprehensive view of the relationships between person factors (e.g., general anxiety/fear, SOR, and DFA) and oral health behaviors and outcomes. This is valuable in order to highlight connections between constructs that may be targeted in the development of new interventions to improve oral health behaviors and outcomes as well as the experience of DFA.
