    Preserved somatosensory conduction in a patient with complete cervical spinal cord injury2015Ingår i: Journal of Rehabilitation Medicine, ISSN 1650-1977, E-ISSN 1651-2081, Vol. 47, nr 5, s. 426-431Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective: Neurophysiological investigation has shown that patients with clinically complete spinal cord injury can have residual motor sparing ("motor discomplete"). In the current study somatosensory conduction was assessed in a patient with clinically complete spinal cord injury and a novel ethodology for assessing such preservation is described, in this case indicating "sensory discomplete" spinal cord injury. Methods: Blood oxygenation level-dependent functional magnetic resonance imaging (BOLD fMRI) was used to examine the somatosensory system in a healthy subject and in a subject with a clinically complete cervical spinal cord injury, by applying tactile stimulation above and below the level of spinal cord injury, with and without visual feedback. Results: In the participant with spinal cord injury, somatosensory stimulation below the neurological level of the lesion gave rise to BOLD signal changes in the corresponding areas of the somatosensory cortex. Visual feedback of the stimulation strongly modulated the somatosensory BOLD signal, implying that cortico-cortical rather than spino-cortical connections can drive activity in the somatosensory cortex. Critically, BOLD signal change was also evident when the visual feedback of the stimulation was removed, thus demonstrating sensory discomplete spinal cord injury. Conclusion: Given the existence of sensory discomplete spinal cord injury, preserved but hitherto undetected somatosensory conduction might contribute to the unexplained variability related to, for example, the propensity to develop decubitus ulcers and neuropathic pain among patients with clinically complete spinal cord injury.

    Interpersonal touch interventions for patients in intensive care: A design-oriented realist review2019Ingår i: Nursing Open, E-ISSN 2054-1058, Vol. 6, nr 2, s. 216-235Artikel, forskningsöversikt (Refereegranskat)
    Abstract [en]

    Aim: To develop a theoretical framework to inform the design of interpersonal touch interventions intended to reduce stress in adult intensive care unit patients.

    Design: Realist review with an intervention design-oriented approach.

    Methods: We searched CINAHL, MEDLINE, EMBASE, CENTRAL, Web of Science and grey literature sources without date restrictions. Subject experts suggested additional articles. Evidence synthesis drew on diverse sources of literature and was conducted iteratively with theory testing. We consulted stakeholders to focus the review. We performed systematic searches to corroborate our developing theoretical framework.

    Results: We present a theoretical framework based around six intervention construction principles. Theory testing provided some evidence in favour of treatment repetition, dynamic over static touch and lightening sedation. A lack of empirical evidence was identified for construction principles relating to intensity and positive/negative evaluation of emotional experience, moderate pressure touch for sedated patients and intervention delivery by relatives versus healthcare practitioners.

    Longitudinal relationships among depressive symptoms, cortisol, and brain atrophy in the neocortex and the hippocampus2018Ingår i: Acta Psychiatrica Scandinavica, ISSN 0001-690X, E-ISSN 1600-0447, Vol. 167, nr 6, s. 491-502Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    OBJECTIVE: Depression is associated with accelerated aging and age-related diseases. However, mechanisms underlying this relationship remain unclear. The aim of this study was to longitudinally assess the link between depressive symptoms, brain atrophy, and cortisol levels.

    METHOD: Participants from the Betula prospective cohort study (mean age = 59 years, SD = 13.4 years) underwent clinical, neuropsychological and brain 3T MRI assessments at baseline and a 4-year follow-up. Cortisol levels were measured at baseline in four saliva samples. Cortical and hippocampal atrophy rates were estimated and compared between participants with and without depressive symptoms (n = 81) and correlated with cortisol levels (n = 49).

    RESULTS: Atrophy in the left superior frontal gyrus and right lingual gyrus developed in parallel with depressive symptoms, and in the left temporal pole, superior temporal cortex, and supramarginal cortex after the onset of depressive symptom. Depression-related atrophy was significantly associated with elevated cortisol levels. Elevated cortisol levels were also associated with widespread prefrontal, parietal, lateral, and medial temporal atrophy.

    CONCLUSION: Depressive symptoms and elevated cortisol levels are associated with atrophy of the prefrontal and limbic areas of the brain.

    Emotional and physiological responses to touch massage2012Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Background: Clinical findings indicate that touch massage has the ability to induce positive emotions and influence stress responses. However, little is known about mechanisms that can explain observed responses.

    Aim: To understand mechanisms behind observed emotional and physiological responses during and after touch massage.

    Methods: This thesis is based upon healthy volunteers in Studies I, II, IV and patients undergone aortic surgery in Study III. Study I had a crossover design, participants served as their own controls. After randomization they received TM on one occasion and the other occasion served as control. Heart rate variability (HRV), heart rate (HR) saliva cortisol concentration, glucose, insulin in serum and extracellular (ECV) levels of glucose, lactate, glycerol and pyruvat were measured before, during and after TM/control. In study II, functional magnetic resonance imaging (fMRI) was used in order to measure brain activity during TM movement. The study design included four different touch stimulations, human touch with movement (TM movement) human stationary touch and rubber glove with or without movement. Force (2.5 N) and velocity (1.5 cm/s) were held constant across conditions. The pleasantness of the four different touch stimulations was rated on a visual analog scale (VAS-scale). Study III had a randomized controlled design. The intervention group received TM and the control group rested. HRV, cortisol, glucose, insulin in serum, blood pressure, oxygen saturation, respiratory frequency and anxiety levels were measured before, during and after TM/control. In study IV participants were interviewed about experiences after TM and the text was analyzed in by qualitative content analyze.

    Results:

    Study I. TM reduced the stress response as indicated by decreased heart rate and decreased activity in the sympathetic nervous system, followed by a compensatory decrease in parasympathetic nervous activity in order to maintain balance. Cortisol and insulin levels decreased significantly after intervention, while serum glucose levels remained stable. A similar, though less prominent, pattern was seen during the control session. There were no significant differences in ECV concentrations of analyzed substances.

    Study II. Human moving touch (TM movement) was significantly rated as the most pleasant touch stimulation. The fMRI results revealed that human moving touch (TM movement) most strongly activated the pregenual anterior cingulate cortex (pgACC).

    Study III. Selfrated anxiety levels significantly decreased in the patient group that received TM compared with control group. There were no significant differences in physiological stress-related outcome parameters between patients who received touch massage and controls.

    Study IV. In this study participants talked about the experience of TM in terms of rewards. Expressions like need, desire, pleasure and conditioning could be linked with a theoretical model of reward. Four different categories were identified as wanting, liking, learning and responding.

    In conclusion: Results from these studies indicate that receiving TM is experienced as rewarding. Touch massage movement activates a brain area involved in coding of rewarding pleasant stimulations. TM decreases anxiety and dampens the stress response by a decreased activation of the sympathetic nervous activity. Our results indicate that TM is a caring intervention that can be used to induce pleasure, decrease anxiety and stress in the receiver.

    Longitudinal Evidence for Smaller Hippocampus Volume as a Vulnerability Factor for Perceived Stress2016Ingår i: Cerebral Cortex, ISSN 1047-3211, E-ISSN 1460-2199, Vol. 26, nr 8, s. 3527-3533Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Hippocampal volume has been found to be smaller in individuals with stress-related disorders, but it remains unclear whether smaller volume is a consequence of stress or rather a vulnerability factor. Here, we examined this issue by relating stress levels to hippocampal volumes in healthy participants examined every 5 years in a longitudinal population-based study. Based on scores of 25- to 60-year-old participants on the perceived stress questionnaire, we defined moderately to high (n = 35) and low (n = 76) stress groups. The groups were re-examined after 5 years (at the 6th study wave). Historical data on subjective stress were available up to 10 years prior to Wave 5. At the first MRI session, the moderately to high stress group had a significantly smaller hippocampal volume, as measured by FreeSurfer (version 5.3), compared with the low-stress group. At follow-up, group differences in stress levels and hippocampal volume remained unchanged. In retrospective analyses of subjective stress, the observed group difference in stress was found to be stable. The long-term stability of group differences in perceived stress and hippocampal volume suggests that a small hippocampal volume may be a vulnerability factor for stress-related disorders.

    Endocannabinoids and related lipids in blood plasma following touch massage: a randomised, crossover study2015Ingår i: BMC Research Notes, ISSN 1756-0500, E-ISSN 1756-0500, Vol. 8, artikel-id 504Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: The endocannabinoid system is involved in the regulation of stress and anxiety. In a recent study, it was reported that short-term changes in mood produced by a pleasant ambience were correlated with changes in the levels of plasma endocannabinoids and related N-acylethanolamines (Schrieks et al. PLoS One 10: e0126421, 2015). In the present study, we investigated whether stress reduction by touch massage (TM) affects blood plasma levels of endocannabinoids and relatedN-acylethanolamines.

    Results: A randomized two-session crossover design for 20 healthy participants was utilised, with one condition that consisted of TM and a rest condition as control. TM increased the perceived pleasantness rating of the participants, and both TM and rest reduced the basal anxiety level as assessed by the State scale of the STAI-Y inventory. However, there were no significant effects of either time (pre- vs. post-treatment measures) as main effect or the interaction time x treatment for the plasma levels of the endocannabinoids anandamide and 2-arachidonoylglycerol or for eight other related lipids. Four lipids showed acceptable relative reliabilities, and for two of these (linoleoyl ethanolamide and palmitoleoyl ethanolamide) a significant correlation was seen between the TM-related change in levels, calculated as (post-TM value minus pre-TM value) − (post-rest value minus pre-rest value), and the corresponding TM-related change in perceived pleasantness.

    Conclusions: It is concluded that in the participants studied here, there are no overt effects of TM upon plasma endocannabinoid levels. Possible associations of related N-acylethanolamines with the perceived pleasantness should be investigated further.

    Touch massage, a rewarding experience2014Ingår i: Journal of Holistic Nursing, ISSN 0898-0101, E-ISSN 1552-5724, Vol. 32, nr 4, s. 261-268Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This study aims to describe and analyze healthy individuals’ expressed experiences of touch massage (TM). Fifteen healthy participants received whole body touch massage during 60 minutes for two separate occasions. Interviews were analyzed by narrative analysis. Four identifiable storyline was found, Touch massage as an essential need, in this storyline the participants talked about a desire and need for human touch and TM. Another storyline was about, Touch massage as a pleasurable experience and the participants talked about the pleasure of having had TM. In the third storyline Touch massage as a dynamic experience, the informants talked about things that could modulate the experience of receiving TM. In the last storyline, Touch massage influences self-awareness, the participants described how TM affected some of their psychological and physical experiences. Experiences of touch massage was in general described as pleasant sensations and the different storylines could be seen in the light of rewarding experiences.

    Touch massage: a pilot study of a complex intervention2013Ingår i: Nursing in Critical Care, ISSN 1362-1017, E-ISSN 1478-5153, Vol. 18, nr 6, s. 269-277Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objectives: To report and evaluate a complex touch massage intervention according to the British Medical Research Council framework. This study aimed to evaluate the effects of touch massage on levels of anxiety and physiological stress in patients scheduled for elective aortic surgery.

    Background: The use of touch massage has increased during the past decade but no systematic studies have been implemented to investigate the effectiveness of such treatment. It is important to conduct multidisciplinary investigations into the effects of complex interventions such as touch massage. For this, the British Medical Research Council has provided a useful framework to guide the development, piloting, evaluation and reporting of complex intervention studies.

    Method: A pilot study with a randomized controlled design including 20 patients (10 + 10) scheduled for elective aortic surgery. Selected outcome parameters included; self-reported anxiety, measured by the State-Trait Anxiety Inventory Form Y instrument, and physiological stress, measured by heart rate variability, blood pressure, respiratory frequency, oxygen saturation and concentrations of cortisol, insulin and glucose in serum.

    Results: There were significant differences in self-reported anxiety levels before and after touch massage (p = 0·007), this was not observed in the control group (p = 0·833). There was a significant difference in self-reported anxiety levels between the touch massage group and the control group after touch massage and rest (p = 0·001). There were no significant differences in physiological stress-related outcome parameters between patients who received touch massage and controls.

    Conclusion: In our study, touch massage decreased anxiety levels in patients scheduled for elective aortic surgery, and the British Medical Research Council framework was a useful guideline for the development, evaluation and reporting of a touch massage intervention.

    Relevance to clinical practice: Touch massage can reduce patients' anxiety levels and is thus an important nursing intervention in intensive and post-operative care.

    Physiological responses to touch massage in healthy volunteers2010Ingår i: Autonomic Neuroscience: Basic & Clinical, ISSN 1566-0702, E-ISSN 1872-7484, Vol. 158, nr 1-2, s. 105-110Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    OBJECTIVES: To evaluate effects of touch massage (TM) on stress responses in healthy volunteers.

    METHODS: A crossover design including twenty-two (mean age=28.2) healthy volunteers (11 male and 11 female) cardiac autonomic tone was measured by heart rate (HR) and heart rate variability (HRV). Stress hormone levels (cortisol) were followed in saliva. We also measured blood glucose and serum insulin. Extracellular (ECV) levels of glucose, lactate, pyruvate and glycerol were followed using the microdialysis technique (MD). TM was performed on hands and feet for 80min, during control, participants rested in the same setting. Data were collected before, during, and after TM and at rest. Saliva cortisol, serum glucose, and serum insulin were collected before, immediately following, and 1h after intervention or control, respectively.

    RESULTS: After 5min TM, HR decreased significantly, indicating a reduced stress response. Total HRV and all HRV components decreased during intervention. Saliva cortisol and insulin levels decreased significantly after intervention, while serum glucose levels remained stable. A similar, though less prominent, pattern was seen during the control situation. Only minor changes were observed in ECV levels of glucose (a decrease) and lactate (an increase). No significant alterations were observed in glycerol or pyruvate levels throughout the study. There were no significant differences between groups in ECV concentrations of analyzed substances.

    CONCLUSIONS: In healthy volunteers, TM decreased sympathetic nervous activity, leading to decreased overall autonomic activity where parasympathetic nervous activity also decreased, thereby maintaining the autonomic balance.

    Pleasant human touch is represented in pregenual anterior cingulate cortex2012Ingår i: NeuroImage, ISSN 1053-8119, E-ISSN 1095-9572, Vol. 59, nr 4, s. 3427-3432Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Touch massage (TM) is a form of pleasant touch stimulation used as treatment in clinical settings and found to improve well-being and decrease anxiety, stress, and pain. Emotional responses reported during and after TM have been studied, but the underlying mechanisms are still largely unexplored. In this study, we used functional magnetic resonance (fMRI) to test the hypothesis that the combination of human touch (i.e. skin-to-skin contact) with movement is eliciting a specific response in brain areas coding for pleasant sensations. The design included four different touch conditions; human touch with or without movement and rubber glove with or without movement. Force (2.5N) and velocity (1.5cm/s) were held constant across conditions. The pleasantness of the four different touch stimulations was rated on a visual analog scale (VAS-scale) and human touch was rated as most pleasant, particularly in combination with movement. The fMRI results revealed that TM stimulation most strongly activated the pregenual anterior cingulate cortex (pgACC). These results are consistent with findings showing pgACC activation during various rewarding pleasant stimulations. This area is also known to be activated by both opioid analgesia and placebo. Together with these prior results, our finding furthers the understanding of the basis for positive TM treatment effects.

    Does touch massage facilitate recovery after stroke?: A study protocol of a randomized controlled trial2016Ingår i: BMC Complementary and Alternative Medicine, ISSN 1472-6882, E-ISSN 1472-6882, Vol. 16, artikel-id 50Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND: Despite high quality stroke care, decreased sensorimotor function, anxiety and pain often remain one year after stroke which can lead to impaired health and dependence, as well as higher healthcare costs. Touch massage (TM) has been proven to decrease anxiety and pain, and improve quality of health in other conditions of reduced health, where reduced anxiety seems to be the most pronounced benefit. Thus there are reasons to believe that TM may also reduce anxiety and pain, and improve quality of life after stroke. Further, several studies indicate that somatosensory stimulation can increase sensorimotor function, and it seems feasible to believe that TM could increase independence after stroke. In this study we will evaluate effects of TM after stroke compared to sham treatment.

    METHODS: This is a prospective randomized open-labelled control trial with blinded evaluation (PROBE-design). Fifty patients with stroke admitted to stroke units will be randomized (1:1) to either a TM intervention or a non-active transcutaneous electrical nerve stimulation (non-TENS) control group. Ten sessions of 30 min treatments (TM or control) will be administered during two weeks. Assessment of status according to the International Classification of Functioning, Disability and Health (ICF), including body function, activity, and participation. Assessment of body function will include anxiety, pain, and stress response (heart rate variability and salivary cortisol), where anxiety is the primary outcome. Activity will be assessed by means of sensorimotor function and disability, and participation by means of health-related quality of life. Assessments will be made at baseline, after one week of treatment, after two weeks of treatment, and finally a follow-up after two months. The trial has been approved by the Regional Ethical Review Board.

    DISCUSSION: TM seems to decrease anxiety and pain, increase health-related quality of life, and improve sensorimotor functions after stroke, but the field is largely unexplored. Considering the documented pleasant effects of massage in general, absence of reported adverse effects, and potential effects in relation to stroke, it is essential to evaluate effects of TM during the sub-acute phase after stroke. The results of this project will hopefully provide important knowledge for evidence-based care.

    TRIAL REGISTRATION: ClinicalTrials.gov: NTC01883947.

    The Efficacy of P6 Acupressure With Sea-Band in Reducing Postoperative Nausea and Vomiting in Patients Undergoing Craniotomy: A Randomized, Double-blinded, Placebo-controlled Study2015Ingår i: Journal of Neurosurgical Anesthesiology, ISSN 0898-4921, E-ISSN 1537-1921, Vol. 27, nr 1, s. 42-50Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Postoperative nausea and vomiting (PONV) is a multifactorial problem after general anesthesia. Despite antiemetic prophylaxis and improved anesthetic techniques, PONV still occurs frequently after craniotomies. P6 stimulation is described as an alternative method for preventing PONV. The primary aim of this study was to determine whether P6 acupressure with Sea-Band could reduce postoperative nausea after elective craniotomy. Secondary aims were to investigate whether the frequency of vomiting and the need for antiemetics could be reduced.

    Methods: In this randomized, double-blinded, placebo-controlled study, patients were randomized into either a P6 acupressure group (n = 43) or a sham group (n = 52). Bands were applied unilaterally at the end of surgery, and all patients were administered prophylactic ondansetron. Postoperative nausea was evaluated with a Numerical Rating Scale, 0 to10, and the frequency of vomiting was recorded for 48 hours.

    Results: We found no significant effect from P6 acupressure with Sea-Band on postoperative nausea or vomiting in patients undergoing craniotomy. Nor was there any difference in the need for rescue antiemetics. Altogether, 67% experienced PONV, and this was especially an issue at >24 hours in patients recovering from infratentorial surgery compared with supratentorial surgery (55% vs. 26%; P = 0.014).

    Conclusions: Unilateral P6 acupressure with Sea-Band applied at the end of surgery together with prophylactic ondansetron did not significantly reduce PONV or the need for rescue antiemetics in patients undergoing craniotomy. Our study confirmed that PONV is a common issue after craniotomy, especially after infratentorial surgery.
