Affective touch in the context of development, oxytocin signaling, and autism.

Touch represents one of our most important senses throughout life and particularly in the context of our social and emotional experiences. In this review, we draw on research on touch processing from both animal models and humans. Firstly, we briefly describe the cutaneous touch receptors and neural processing of both affective and discriminative touch. We then outline how our sense of touch develops and summarize increasing evidence demonstrating how essential early tactile stimulation is for the development of brain and behavior, with a particular focus on effects of tactile stimulation in infant animals and pediatric massage and Kangaroo care in human infants. Next, the potential mechanisms whereby early tactile stimulation influences both brain and behavioral development are discussed, focusing on its ability to promote neural plasticity changes and brain interhemispheric communication, development of social behavior and bonding, and reward sensitivity through modulation of growth factor, oxytocin, and opioid signaling. Finally, we consider the implications of evidence for atypical responses to touch in neurodevelopmental disorders such as autism spectrum disorder and discuss existing evidence and future priorities for establishing potential beneficial effects of interventions using massage or pharmacological treatments targeting oxytocin or other neurochemical systems.

Tactile information affects alternating visual percepts during binocular rivalry using naturalistic objects

IntroductionPast studies have provided evidence that the effects of tactile stimulation on binocular rivalry are mediated by primitive features (orientation and spatial frequency) common in vision and touch. In this study, we examined whether such effects on binocular rivalry can be obtained through the roughness of naturalistic objects. In three experiments, the total dominant time of visual percepts of two objects was measured under binocular rivalry when participants touched one of the objects.ResultIn Experiment 1, the total dominant time for the image of artificial turf and bathmat was prolonged by congruent tactile stimulation and shortened by incongruent tactile stimulation. In Experiment 2, we used the same stimuli but rotated their visual images in opposite directions. The dominant time for either image was prolonged by congruent tactile stimulation. In Experiment 3, we used different types of stimuli, smooth marble and rough fabric, and noted significant effects of the congruent and incongruent tactile stimulation on the dominant time of visual percepts.ConclusionThese three experiments demonstrated that visuo-tactile interaction on binocular rivalry can be mediated by roughness.

A systematic review and meta-analysis on the use of tactile stimulation in vection research.

Vection is classically defined as the illusory perception of self-motion induced via visual stimuli. The utility of vection research lies in its potential to enhance simulation fidelity, as measured through presence, and reduce the probability that motion sickness symptoms occur. Studies have shown a multimodal interaction of various sensory systems in facilitating vection, and the utility of co-stimulating some of these sensory systems along with the presentation of visual stimuli have been reviewed. However, a review on the use of tactile stimulation in vection research appears to be missing from literature. The purpose of this review was to evaluate the current methodologies, and outcomes, of tactile stimulation in vection research. We searched for articles through EBSCOHost, Scopus and Web of Science. Studies were included only if they detailed an experiment on the effect of tactile stimulation on vection. Twenty-four studies were obtained and distilled in tabular form. Eighteen studies contained sufficient information to be included in a meta-analysis. We identified that tactile stimulation has mostly been applied in the form of vibrational stimulation to the feet. Furthermore, tactile stimulation is most effective when it is presented in a temporally congruent manner to other sensory cues, whereas tactile stimulation as a unisensory stimulus does not appear to be effective in eliciting vection. We discuss the need for more qualitative research to reduce methodological inhomogeneities and recommend future research in tactile-mediated vection to investigate stimulation to the torso and investigate the use of forces as a tactile stimulus.

Effects of tactile stimulation on the sensory, motor and cognitive function in people with multiple sclerosis

ObjectiveMultiple sclerosis (MS) is a chronic inflammatory neurodegenerative disease that causes demyelination in the brain and spinal cord. Repetitive sensory stimulation (RSS) can enhance sensory perception and motor function, improve inappropriate synaptic connections and adaptable malformations, and increase cognitive function. The purpose of this study was to specify the effect of RSS on the sensory, motor, and cognitive function in people with MS. MethodsRSS was applied to 50 people with MS. In this study, the following tests were used: two-point discrimination, 9-Hole Peg Test (9-HPT), Box and Block Test (BBT), hand mental rotation (HMR), Paced Auditory Serial Addition Test (PASAT), and Symbol Digit Modalities Test (SDMT). The tests were performed before and after the intervention. ResultsThe results of this study showed significant difference before and after the stimulation in intervention and control groups two-point discrimination threshold (both groups= 0.001), BBT score (both groups: P < 0.001) and 9-HPT score (both groups: P < 0.001), HMR ability (reaction time: both groups: P = 0.003; accuracy rate: intervention: P = 0.004, control: P < 0.001), PASAT score (intervention: P < 0.001, control: P = 0.012) and SDMT score (intervention: P = 0.008, control: P < 0.001), but there was no statistical difference observed between the two groups before and after the intervention in terms of the mentioned variables (P > 0.05). ConclusionThe application of 30 min of RSS in the right index finger of people with MS could not improve the two-point discrimination threshold and the manual dexterity. In addition, this intervention did not improve cognitive function.

EFFECT OF TACTILE STIMULATION ON NEONATAL STRESS DURING INVASIVE PROCEDURES AT NEONATAL INTENSIVE CARE UNITS OF PORT SAID

Background:Tactile stimulation has a great effect on decreasing neonatal stress during invasive procedures in neonatal intensive care units. Aim of the study: The study aimed to assess the effect of tactile stimulation on neonatal stress during invasive procedures at neonatal intensive care units. Design and setting: A quasi-experimental research design was used in this study, which was implemented in neonatal intensive care units Port Said, Port-Fouad and El-Nasr General Hospitals in Port Said. Sample: A sample of 130 neonates were used in the study. Tools: Data were collected by using three tools the first for neonatal characteristics, the second for assessment of neonatal blood sample (invasive procedure) and the third for stress physiological, behavioral & motor measurements. Results: There were high statistically significant differences in physiological, behavioral & motor measurements between two methods (with & without tactile stimulation) and the degree of neonatal stress control during invasive procedures in NICUs. Moreover, there was high statistically significant differences between two methods (with & without tactile stimulation) regarding total stress score and the degree of neonatal stress control during invasive procedures in NICUs, p value <0.001. Conclusion: The application of tactile stimulation has a positive effect on neonatal degree of stress among daily painful invasive procedures in NICUs. Recommendations: Continues implementing training program on tactile stimulation technique as a technical skill for nursing staff and implement further studies to investigate the effect of tactile stimulation on stress in different settings.

Effect of Tactile Stimulation and Joint Integrity Exercises on Hemineglect in Stroke Survivors

Background: Unilateral spatial neglect is likely to be associated with poor functional outcome in sub acute phase. During this period, intensive rehabilitation is needed to obtain higher ADL scores. If greater efficacy of rehabilitation can be brought about by early intervention for unilateral spatial neglect, patients with unilateral neglect might achieve higher ADL goals. Material and Method: In this pre-post intervention study 25 neglect patients were included with less than six month of stroke.Tactile stimulations and joint integrity exercise protocol was set for four weeks. After pre-post assessment, data was analysed with help of appropriate statistical methods. Results: According to this study, there is increase in tactile stimulation (p=0.0023), kinaesthetic stimulation (p&lt;0.0001),stereognosis (p&lt;0.0001) and motor outcome (p=0.0001). This indicates an overall increase in sensory and motor outcome. Conclusion: Tactile stimulation and joint integrity exercises appears to be beneficial for improving motor outcome in hemineglect patients after stroke.

Effect of Tactile Stimulation on Hand Mental Rotation Among Young Healthy Adults: A Randomized Controlled Trial

Background: In the hand mental rotation task, images and line drawings of hand at different angles are shown to the subjects, and they are asked to choose which hand (left or right) it is. Tactile stimulation is an appropriate technique to improve sensory and motor functions. Objectives: The present study aimed to investigate the impact of tactile stimulation on the hand mental rotation task. Methods: To meet the study objectives, 91 right-handed university students were selected to participate in this study. They were randomly divided into control (n = 41) and tactile stimulation (n = 50) groups. Participants were asked to perform a hand mental rotation task before and after tactile stimulation. The task required participants to judge the laterality (left or right) of hands as quickly and accurately as possible. The tactile stimulation was applied to the right index fingertip (16 Hz for 30 min). Results: In the tactile stimulation group, all angles for both right- and left-hand participants were analyzed, demonstrating significant decreases in the reaction time (P = 0.004) after tactile stimulation (mean: 1,908.24 ± 375.42 to 1,721.21 ± 428.99 milliseconds). In this group, the response accuracy rate increased considerably (P < 0.001) after tactile stimulation (mean: 78.43% ± 16.58 to 84.38% ± 18.15). In the control group, no significant differences were found between the measured parameters before and after sham stimulation. Conclusions: The current study demonstrated that tactile stimulation could improve hand mental rotation in healthy young adults, probably due to increased brain excitability and plasticity.

Effect of Tactile Stimulation on Termination and Prevention of Apnea of Prematurity: A Systematic Review.

Apnea of prematurity (AOP) is one of the most common diagnoses in preterm infants. Severe and recurrent apneas are associated with cerebral injury and adverse neurodevelopmental outcome. Despite pharmacotherapy and respiratory support to prevent apneas, a proportion of infants continue to have apneas and often need tactile stimulation, mask, and bag ventilation and/or extra oxygen. The duration of the apnea and the concomitant hypoxia and bradycardia depends on the response time of the nurse. We systematically reviewed the literature with the aim of providing an overview of what is known about the effect of manual and mechanical tactile stimulation on AOP. Tactile stimulation, manual or mechanical, has been shown to shorten the duration of apnea, hypoxia, and or bradycardia or even prevent an apnea. Automated stimulation, using closed-loop pulsating or vibrating systems, has been shown to be effective in terminating apneas, but data are scarce. Several studies used continuous mechanical stimulation, with pulsating, vibrating, or oscillating stimuli, to prevent apneas, but the reported effect varied. More studies are needed to confirm whether automated stimulation using a closed loop is more effective than manual stimulation, how and where the automated stimulation should be performed and the potential side effects.

Effects of tactile stimulation by fathers on physiological responses and paternal attachment in infants in the NICU: A pilot study.

The aims of our pilot study were to test (1) the effectiveness of tactile stimulation by fathers on their infants' physiological responses such as oxygen saturation levels, heart rates (HRs), and respiration rates (RRs) and (2) fathers' perceived levels of attachment to infants in the neonatal intensive care unit (NICU). This was a quasi-experimental design using a control group, which assessed pre- and post-intervention differences via t tests. Twenty neonate-father dyads participated in the intervention and 20 neonate-father dyads populated a control group from one general hospital located in South Korea. Infants in the experimental group received tactile stimulation for one 10-minute period per day, for five consecutive days. Overall, we found that tactile stimulation by fathers significantly stabilized infants' physiological status, including oxygen saturation levels, HRs, and RRs ( t = 2.138, p = .039; t = -2.348, p = .024; t = -3.461, p = .001, respectively) with effect size ranged 0.67-1.10 and increased paternal attachment levels ( t = 3.982, p = .001) with large effect size (1.29). This pilot study suggests that tactile stimulation by the father may be regarded as an important and potentially useful intervention for the care of infants in the NICU.

Epub 2011 Oct 28. o This project was supported by National Institutes of Health (NIH) Grant K24MH087913 (KJB) and a Tourette Syndrome Association fellowship (DJG). Additional support from Clinical and Translational Science Award (CTSA) Grant [UL1 TR000448] and Siteman Comprehensive Cancer Center and NCI Cancer Center Support Grant P30 CA091842 This study was a continuation of “Towards objectively quantifying sensory hypersensitivity: a pilot study of the Ariana effect“ (Panagopoulos et al., 2013). It aimed to test the extent to which sensory hypersensitivity in patients with TS/CTD affects sustained attention. To do this, participants with and without TS/CTD performed an attention task in the presence and absence of a subtle sensory stimulus. Tourette Syndrome and Chronic Tic Disorder (TS/CTD) are complex neuropsychiatric disorders in which patients present with multiple motor or vocal tics. In many patients with TS/CTD, attentional problems are present and ADHD is the most common condition that co-occurs with TS/CTD, occurring in about 50% of patients (Greimel et al, 2011). These attentional problems can range from mild to severe and can impact the patient’s ability to complete tasks, sustain attention, and keep track of personal items.

Effect of tactile stimulation in common human–dog interactions on the behavior and physiology of dogs

in any element of Group D were significantly associated with a history of biting dogs (P 5 0.001), producing 54.9% correct positives. Other factors influencing aggression scores and biting history included sex, breed, and obedience. Intact males bit other dogs with high probability (c 5 16.4, df 5 3, P 5 0.001). There also was a breed difference for high aggression scores in Group D (c 5 36.7, df 5 14, P 5 0.001) and for a history of biting dogs (c 5 33.1, df 5 14, P 5 0.003). A biting history with dogs was not significantly correlated to any particular form of training, but a poor obedience score was correlated with high aggression scores in Group D (K-W c 5 19.2, df 5 3, p , 0.001), and there was also a breed difference for obedience (K-W c 5 37.0, df 5 3, P , 0.001). Owners using physical punishment had dogs with low obedience levels (K-W c 5 30.9, df 5 3, P , 0.001). The opposite applied for using verbal reinforcement (K-W c 5 24.2, df 5 3, P , 0.001). These preliminary results show that such formal tests, done by experts in a standardized way, appear to be useful retrospective tools for identifying danger originating from dogs. Whether such dog–dog tests are of any prospective use needs to be investigated further. Many factors influence dog behavior in individual situations. All factors have to be thoroughly evaluated, especially as they interact with and influence each other. Further research will need to emphasize the owner’s influence, beginning with the initial decision to purchase a particular breed.

Effects of tactile stimulation and underwater trauma on the behavior of protein-malnourished rats in the elevated plus-maze test

The objective of the present study was to evaluate the interaction of two kinds of external stimuli (long-term tactile stimulation and underwater trauma) on the exploratory behavior of malnourished rats in an elevated plus maze (EPM). The results showed that tactile stimulation partially recovered body weight deficits produced by malnutrition and decreased EPM exploration. Malnutrition increased EPM exploration while underwater trauma decreased it, thus reducing differences between well nourished and malnourished animals. These data show that only one of the two external stimuli (underwater trauma) interacted with diet condition, suggesting that the stress caused by trauma was efficient in decreasing higher EPM exploration, equalizing the response of malnourished animals to that of non-traumatized well-nourished animals.

Effect of Tactile Stimulation on Lingual Motor Function in Pediatric Lingual Dysphagia

The study by Lamm et al. [1] consisted of 45 patients who did not swallow because of multiple congenital anomalies and gastroenterologic dysfunctions before and after corrective surgery and who also had histories of unsuccessful traditional feeding intervention. The purpose of their study was to ‘‘(1) isolate the specific regional mechanical functions of the tongue during swallowing; (2) identify the specific controlling variables that induce physiologic mechanical actions as varied tongue positions and tone during a swallow in young children fed through artificial means who had not swallowed food before treatment; (3) replicate (our) 26 preliminary results of inducing and maintaining a swallow reflex across a large number of young children with lingual dysphagia; and (4) provide an alternative procedure to surgical gastrostomy placement and removal of gastrostomy button or nasogastric tube.’’ The various procedures implemented were found to be ‘‘useful across the board for all patients with severe dysphagia.’’ The various procedures employed resulted in independent swallows in 96% or 43 of 45 of the patients studied, with 42 of the 45 patients also demonstrating a 100% transfer from gastrostomy or nasogastric tube feedings to oral hydration and nutrition. Lamm et al. concluded that the various procedures they implemented ‘‘although intense and lengthy in systematic components, yield prudent results in 5–7 days of inpatient treatment. They are feasible for patients with lingual dysphagia who do not swallow and for whom aspiration is a real danger. These outcomes provide an empiric preventative procedure to surgical gastrostomy placement and may facilitate the timely removal of a gastrostomy button and nasogastric tube in candidate patients.’’ The members of the Pediatric Swallowing Disorders and Oral Feeding Clinic programs at the Children’s Hospital, Denver, CO, were intrigued by Lamm et al. article [1]. The level of success detailed in the article in transforming nonoral feeders into full oral feeders over a five-day span is nothing short of astounding. To our knowledge it is not an achievement that is mirrored in other behavioral feeding programs currently operating within the United States nor is it an achievement that our own feeding program has been able to obtain. Despite the impressive outcomes described, there were aspects of this article that are of concern and/or contrary to our clinical experience for which we seek clarification, specifically:

Effect of Tactile Stimulation on Lingual Motor Function in Pediatric Lingual Dysphagia

There is a scarcity of empirical evidence on effective treatments of swallowing dysfunction in young children who do not suck or swallow. There is no literature testing the effects of shaping a reflex or specifically shaping a swallow reflex. The purpose of this retrospective study was to investigate and isolate the specific regional mechanical functions of the tongue during swallowing. This study included 45 patients who did not swallow because of multiple congenital anomalies and gastroenterologic dysfunctions before and after corrective surgery and had histories of unsuccessful traditional feeding therapies. Evaluation included clinical gastroenterologic, nutritional, and neurologic examination, routine laboratory tests, and radiologic swallowing studies. A ten-year study analyzed the behavioral science procedures shaping both a swallow reflex and lingual surface geometry. Treatment variables were (1) a tactile stimulus to the posterior tongue and (2) sequential tactile stimuli to varied locations on the lingual surface. There were significant differences in lingual responses for all patients who were transferred from artificial feedings to independent prototypical swallowing capability and acquired oral consumption of recommended daily hydration and nutrition in 5-7 days of treatment. The initial tactile stimulus and six-level sequential stimuli resulted in six sequential lingual responses within each wavelike swallow reflex. Results of stimuli shaping varied lingual responses across 45 patients with severe multiple medical and anatomical deficits in swallowing, suggest that the etiology was not relevant in this population. These behavioral science approaches are novel treatment for pediatric lingual dysphagia.
