RESUMEN

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.

RESUMEN

Purpose: The purpose of the study was to illuminate the experience of caring touch in intensive care from the perspectives of patients, next-of-kin, and healthcare professionals. Design and Method: This study was explorative, and data were collected through qualitative observations (n = 9) with subsequent interviews (n = 27) at two general intensive care units. An inductive approach was embraced to be open-minded to the participants' experiences. Findings: The results are presented in one generic category-caring touch creates presence-which generated five subcategories: to touch and be touched with respect, touch as guidance and communication, touch causes suffering, touch creates compassion, and touch creates security. Conclusion: When the ability to communicate with words is lost, it is body language that reveals what a person is trying to express. Nurses create a way of being present with the patients by touching them, to communicate I am here for you. Caring touch is a tool to show compassion and respect and to protect the integrity of the lived body. The caring touch is soothing and comforting for the patient and next-of-kin and creates security. It also helps to awaken the motivation to get healthy, which is needed in an environment that is foreign.

RESUMEN

Pleasant brush therapies may benefit those with autism, trauma, and anxiety. While studies monitor brushing velocity, hand-delivery of brush strokes introduces variability. Detailed measurements of human-delivered brushing physics may help understand such variability and subsequent impact on receivers' perceived pleasantness. Herein, we instrument a brush with multi-axis force and displacement sensors to measure their physics as 12 participants pleasantly stroke a receiver's forearm. Algorithmic procedures identify skin contact, and define four stages of arrival, stroke, departure, and airtime between strokes. Torque magnitude, rather than force, is evaluated as a metric to minimize inertial noise, as it registers brush bend and orientation. Overall, the results of the naturally delivered brushing experiments indicate force and velocity values in the range of 0.4 N and 3-10 cm/s, in alignment with prior work. However, we observe significant variance between brushers across velocity, force, torque, and brushstroke length. Upon further analysis, torque and force measures are correlated, yet torque provides distinct information from velocity. In evaluating the receiver's response to individual differences between brushers of the preliminary case study, higher pleasantness is tied to lower mean torque, and lower instantaneous variance over the stroke duration. Torque magnitude appears to complement velocity's influence on perceived pleasantness.

RESUMEN

This scoping review focused on the existing scholarly literature exploring sensory interventions and immersive environments developed for, and used by, older adults living with dementia. The purpose of the scoping review is 1) to understand the various sensory interventions that have been developed, used, and have provided data to show how such interventions are expected to impact the lives of individuals living with dementia; and 2) to understand how the field is moving forward. We chose to map the literature to understand the types of interventions, the types of outcomes measured, and the contexts of their implementation. Our search was constrained to references from 1990 to 1 June 2019 in the following databases: Academic Search Complete, CINAHL Complete, MEDLINE, PsycINFO databases, and Summon Search discovery layer. We screened 2305 articles based on their titles and abstracts, and 465 were sent to full text review, of which 170 were included in our full text extraction. Once the data were extracted, we created emic categories, which emerged from the data, for data that were amenable to categorization (e.g., study setting, intervention type, and outcome type). We developed ten different categories of interventions: art, aromatics, light, multi-component interventions, multisensory rooms, multisensory, music, nature, touch, and taste. Sensory interventions are a standard psychosocial approach to managing the personal expressions commonly experienced by people living with dementia. Our findings can help providers, caregivers, and researchers better design interventions for those living with dementia, to help them selectively choose interventions for particular outcomes and settings. Two areas emerging in the field are nature interventions (replacing traditional "multisensory rooms" with natural environments that are inherently multisensory and engaging) and multi-component interventions (where cognitive training programs are enhanced by adding sensory components).

RESUMEN

With the growing popularity of complementary and alternative medicine (CAM) among individuals with chronic pain and muscular problems, a number of patients with rheumatoid arthritis (RA) show their interest in CAM interventions for disease improvement. Various reports published on CAM are based on an animal model of RA; however, there is often a lack of high-quality clinical investigations for explaining the success stories of CAM therapies in patients with RA. CAMs having the potential to be used for therapy in patients with RA have been identified, however lack of awareness and skepticism of their efficacy has made the patients reluctant to choose these drug-less therapies. In this review, we have summarized the existing evidence which suggests promising efficacy of different alternative therapies in managing RA and providing both physical and mental well-being to RA patients.

RESUMEN

Background@#Kangaroo Mother Care (KMC) has facilitated infant growth and decreased morbidities and hospital stay. Adding touch therapy (TT) may potentiate the KMC benefits. @*Objective@#To compare the effectiveness of KMC+TT versus KMC alone in improving anthropometric and physiologic parameters and decreasing morbidities and hospital stay in low birth weight (LBW) infants. @*Methods@#Stable LBW infants (<2000 g) admitted in the KMC ward were randomized to either intervention (KMC+TT) or control (KMC only) group. The KMC+TT group underwent thrice daily touch therapy sessions until discharge. @*Results@#A total of 50 infants were included in the study. Baseline characteristics between the two groups were comparable. There was a significant increase in weight gain (grams/kg/day) in the KMC+TT group compared to KMC only. Physiologic parameters like heart rate, respiratory rate, and temperature were significantly better in the KMC+TT group. More infants in the KMC only group were transferred to NICU care, while more KMC+TT infants went home against advice. Hospital stay was similar between the two groups. @*Conclusion@#Touch therapy added to KMC is more effective than KMC alone in improving weight gain and physiologic parameters. It is associated with lower morbidities, although it did not affect the hospital stay.

RESUMEN

Physical and psychological therapy based on touch has been gradually integrated into broader mental health settings in the past two decades, evolving from a variety of psychodynamic, neurobiological and trauma-based approaches, as well as Eastern and spiritual philosophies and other integrative and converging systems. Nevertheless, with the exception of a limited number of well-known massage therapy techniques, only a few structured protocols of touch therapy have been standardized and researched to date. This article describes a well-defined protocol of touch therapy in the context of psychotherapy-the Calatonia technique-which engages the orienting reflex. The orienting reflex hypothesis is explored here as one of the elements of this technique that helps to decrease states of hypervigilance and chronic startle reactivity (startle and defensive reflexes) and restore positive motivational and appetitive states.

RESUMEN

BACKGROUND: The use of complementary and alternative medicine (CAM) techniques has been growing. The National Center for Complementary and Alternative Medicine places therapeutic touch (TT) into the category of bio field energy. This literature review is aimed at critically evaluating the data from clinical trials examining the clinical efficacy of therapeutic touch as a supportive care modality in adult patients with cancer. METHODS: Electronic databases (PubMed, Scopus, Scholar Google, and Science Direct) were searched from the year 1990 to 2015 to locate potentially relevant peer-reviewed articles using the key words therapeutic touch, touch therapy, neoplasm, cancer, and CAM. Additionally, relevant journals and references of all the located articles were manually searched for other potentially relevant studies. RESULTS: The number of 334 articles was found on the basis of the key words, of which 17 articles related to the clinical trial were examined in accordance with the objectives of the study. A total of 6 articles were in the final dataset in which several examples of the positive effects of healing touch on pain, nausea, anxiety and fatigue, and life quality and also on biochemical parameters were observed. CONCLUSION: Based on the results of this study, an affirmation can be made regarding the use of TT, as a non-invasive intervention for improving the health status in patients with cancer. Moreover, therapeutic touch was proved to be a useful strategy for adult patients with cancer.

RESUMEN

Seven male children with autism spectrum disorder (ASD), aged 8-12 years, attending special education classrooms for ASD and disabled children, were assigned to receive touch therapy. Their mothers were instructed to provide gentle touch in the massage style of the International Liddle Kidz Association. The mothers gave massages to their child for 20 min every day over a period of 3 months, followed by no massage for 4 months. To assess the biological effects of such touch therapy, saliva was collected before and 20 min after a single session of massage for 20 min from the children and mothers every 3 weeks during the massage period and every 4 weeks during the non-massage period, when they visited a community meeting room. Salivary oxytocin levels were measured using an enzyme immunoassay kit. During the period of massage therapy, the children and mothers exhibited higher oxytocin concentrations compared to those during the non-massage period. The changes in oxytocin levels before and after a single massage session were not significantly changed in children and mothers. The results suggested that the ASD children (massage receivers) and their mothers (massage givers) show touch therapy-dependent changes in salivary oxytocin concentrations.
