Active digital pedagogies as a substitute for clinical placement during the COVID-19 pandemic: the case of physiotherapy education.

BACKGROUND: In March 2020, campuses at Norwegian academic institutions were closed due to the COVID-19 pandemic. All in-person teaching had to be replaced by digital alternatives. The closure also affected clinical placements in physiotherapy programs, which in some cases had to be replaced by online alternatives without patient contact. The aim of this study is to evaluate the benefits and challenges of using digital pedagogies to accomplish the learning outcomes of clinical placements. METHODS: Forty-four final-year physiotherapy students at Oslo Metropolitan University had their clinical placement substituted by an online alternative centered around two main educational activities conducted online in small groups: 1) clinical case seminars and 2) digital lectures followed by webinars where students discussed and solved tasks related to the lectures. Additionally, as a part of this alternative placement, students had to conduct a physiotherapy assessment of a family member/housemate and summarize the findings in an anonymized medical record. At the end of the placement, all students wrote a short essay reflecting on their learning process. Students' written reflections were anonymized and subjected to a qualitative analysis. RESULTS: Forty-three out of 44 participating students completed their essays. Although students expressed disappointment in missing out on clinical placement, they were surprised by how much learning the online alternative provided. The most valued activities were clinical case seminars where clinical cases previously experienced by the students were discussed. The seminars appeared to facilitate students' engagement in professional discussions and to enhance their clinical reasoning skills. Seminars also seemed to strengthen students' belief in their own and their fellow students' capabilities. Group discussions focusing on topics related to digital lectures were also appreciated. Interestingly, the activity that most closely mimicked a clinical setting - physiotherapy assessment of family member/housemate - was rarely mentioned in the students' essays. As expected, students most regret not meeting real patients and missing out on the new clinical experiences such encounters would provide. CONCLUSIONS: Despite lack of direct patient contact, students in physiotherapy education evaluated that an online alternative placement was highly clinically relevant. Peer-to-peer discussions of clinical cases appeared to be especially valued. The fact that students themselves had to take the main responsibility for preparing the seminars and leading the discussions was an important pedagogical aspect of the online alternative. The findings indicate that in learning of clinical skills, physiotherapy students take benefit of autonomous, student-centered interventions. Further research should investigate how digital technology-enhanced learning can be used to improve quality of ordinary clinical placement, in physiotherapy- and health education.

The Tampon Test as a Primary Outcome Measure in Provoked Vestibulodynia: A Mixed Methods Study.

BACKGROUND: Provoked vestibulodynia (PVD) is characterized by severe pain, often induced by penetrative sex. This may lead to women abstaining from sexual intercourse, hence the recording of pain intensity levels in PVD research is often challenging. The standardized tampon test was designed as an alternative outcome measure to sexual intercourse pain and has frequently been used in clinical studies. AIM: The aim of this mixed methods study is to evaluate the tampon test as a primary outcome measure for an upcoming randomized clinical trial for women with PVD. METHODS: An explanatory sequential design was applied, integrating quantitative and qualitative methods. In phase one, pain intensity levels were evaluated with the tampon test amongst 10 women, aged 18-33, with PVD. The test was repeated on day 1, 7 and 14. Pain intensity was rated on the Numerical Rating Scale (NRS), (0-10), 10 being worst possible pain. In phase two, the participants' experiences with the test were explored with semi-structured interviews using a descriptive and inductive qualitative design. All participants were recruited from the Vulva Clinic, Oslo University Hospital, Norway. OUTCOMES: The tampon test data and interviews were brought together to see how the interviews could refine and help to explain the quantitative findings. RESULTS: The tampon test data demonstrated large intra- and inter-individual variability. Median tampon pain intensity was 4.5 (min=1.7; max=10; Q1=2.5; Q3=6). Many experienced the test as an inadequate representation of pain during intercourse as it was less painful, different in nature and conducted in an entirely different context. Four participants had a mean score of four or lower on the NRS, whilst concurrently reporting high levels of pain during sexual intercourse. CLINICAL IMPLICATIONS: The findings indicate that the tampon test may underestimate severity of pain among some women with PVD. Participants with low pain scores would be excluded from studies where the tampon test is part of the trial eligibility criteria, even though severe pain was experienced during sexual intercourse. Large intra-individual variability in pain scores also reduces the test's ability to register clinical meaningful changes and hence necessitates repeated measurements per assessment time point. CONCLUSION: Although the tampon test has many advantages, this study indicates several potential problems with the application of the test as a primary outcome measure in PVD. In our opinion the test is most useful as a secondary outcome, preferably undertaken repeatedly in order to increase precision of the pain estimation. Kaarbø MB, Danielsen KG, Haugstad GK, et al.

Group-based multimodal physical therapy in women with chronic pelvic pain: A randomized controlled trial.

INTRODUCTION: Chronic pelvic pain in women is a complex condition, and physical therapy is recommended as part of a broader treatment approach. The objective of this study was to compare structured group-based multimodal physical therapy in a hospital setting (intervention group) with primary-care physical therapy (comparator group) for women with chronic pelvic pain. MATERIAL AND METHODS: Women aged 20-65 years with pelvic pain ≥6 months and referred for physical therapy were eligible. The primary outcome measure was change in the mean pelvic pain intensity from baseline to 12 months, measured using the numeric rating scale (0-10). Secondary outcomes were changes in scores of "worst" and "least" pain intensity, health-related quality of life, movement patterns, pain-related fear of movements, anxiety and depression, subjective health complaints, sexual function, incontinence, and obstructed defecation. The differences between the groups regarding change in scores were analyzed using the independent t test and Mann-Whitney U test. Sensitivity analysis of the primary outcome was performed with a linear regression model adjusted for the baseline value. A P value <.05 was considered statistically significant. RESULTS: Of the 62 women included, 26 in the intervention group and 25 in the comparator group were available after 12 months for data collection and analysis. The difference between the groups for change in the mean pain intensity score was -1.2 (95% CI -2.3 to -0.2; P = .027), favoring the intervention group. The intervention group showed greater improvements in respiratory patterns (mean difference 0.9; 95% CI 0.2-1.6; P = .015) and pain-related fear of movements (mean difference 2.9; 95% CI -5.5 to -0.3; P = .032), and no significant differences were observed between the groups for the other secondary outcomes. CONCLUSIONS: Although the reduction in the mean pelvic pain intensity with group-based multimodal physical therapy was significantly more than with primary-care physical therapy, the difference in the change between the groups was less than expected and the clinical relevance is uncertain.

A conceptual model for managing sexual pain with somatocognitive therapy in women with provoked vestibulodynia and implications for physiotherapy practice.

Somatocognitive therapy is a multimodal physiotherapy treatment developed in the early 2000s to alleviate the burden of chronic pelvic pain. In recent years, somatocognitive therapy has been further developed to treat women with provoked vestibulodynia. This prevalent gynecological pain condition is a subgroup of chronic pelvic pain and the most common form of vulvodynia. Provoked vestibulodynia is a neglected multifactorial pain condition of unknown cause, adversely affecting women's sexual life, relation to their partners and their psychological health. Pain is located at the vulvar vestibule and is provoked by touch or pressure such as sexual intercourse. In the management of sexual pain, somatocognitive therapy combines bodily exploration, pain education, cognitive coping strategies and structured homework to improve sexual function and reduce pain. To support these processes, developing a sound therapeutic alliance with the patient is essential. The aim of this article is to provide a conceptual model for managing provoked vestibulodynia with somatocognitive therapy, including a theoretical rational for this treatment. We base our conceptual model on the biopsychosocial model, i.e., considering the complex interplay of biomedical, emotional/cognitive, psychosexual and interpersonal factors in provoked vestibulodynia management. In addition, implications for practice and a detailed description of somatocognitive therapy for provoked vestibulodynia will be provided, to allow replication in clinical practice and in clinical trials.

Absence of somatization in non-coeliac gluten sensitivity.

OBJECTIVE: In contrast to coeliac disease (CD), the mechanism behind non-coeliac gluten sensitivity (NCGS) is unclear. The aims of the study were to measure the presence of somatization, personality traits, anxiety, depression, and health-related quality of life in NCGS individuals compared with CD patients and healthy controls, and to compare the response to gluten challenge between NCGS and CD patients. MATERIAL AND METHODS: We examined 22 CD patients and 31 HLA-DQ2+ NCGS patients without CD, all on a gluten-free diet. All but five CD patients were challenged orally for 3 days with gluten; symptom registration was performed during challenge. A comparison group of 40 healthy controls was included. Patients and healthy controls completed questionnaires regarding anxiety, depression, neuroticism and lie, hostility and aggression, alexithymia and health locus of control, physical complaints, and health-related quality of life. RESULTS: The NCGS patients reported more abdominal (p = 0.01) and non-abdominal (p < 0.01) symptoms after gluten challenge than CD patients. There were no significant differences between CD and NCGS patients regarding personality traits, level of somatization, quality of life, anxiety, and depressive symptoms. The somatization level was low in CD and NCGS groups. Symptom increase after gluten challenge was not related to personality in NCGS patients. CONCLUSIONS: NCGS patients did not exhibit a tendency for general somatization. Personality and quality of life did not differ between NCGS and CD patients, and were mostly at the same level as in healthy controls. NCGS patients reported more symptoms than CD patients after gluten challenge.

Feasibility and acceptability of somatocognitive therapy in the management of women with provoked localized vestibulodynia-ProLoVe feasibility study.

BACKGROUND: Provoked vestibulodynia (PVD) is a prevalent chronic pain condition especially among young women. Pain is localized to the vulvar vestibule and is provoked by touch or pressure, such as penetrative intercourse. PVD can have profound consequences, adversely affecting a woman's sexual life, relation to her partner, and her psychological health. There is an urgent need for well-designed randomized clinical trials (RCTs) to identify the most effective interventions for this neglected women's health condition. AIMS: The primary aim of this study is to assess the feasibility of undertaking a full-scale RCT of somatocognitive therapy (SCT), a multimodal physiotherapy intervention, for women with PVD. The secondary aim is to evaluate the implementation and acceptability of SCT and its potential treatment effectiveness in PVD. In the full-scale RCT, SCT will be compared to standard PVD treatment. METHODS: A multimethod feasibility study with a single-arm before-after trial and qualitative interviews. Ten women with PVD, aged 18-33 were recruited from the Vulva Clinic at Oslo University Hospital. The intervention took place at Oslo Metropolitan University. Participants were assessed at baseline, post-treatment, and the 8-month follow-up with the tampon test and self-report questionnaires. The main feasibility outcomes were evaluation of recruitment rate, adherence to assessment tools, and follow-up rate. The participants' experiences with the primary outcome and the intervention were explored with semi-structured interviews. RESULTS: Ten out of 18 eligible patients were recruited over 11 weeks. None were lost to follow-up. Adherence to self-report questionnaires was excellent. Adherence to tampon tests and to the reporting of treatments was good, whereas adherence to the 14-day diary was poor. No adverse events were reported. The tampon test was suboptimal as a primary outcome. SCT was found to be an acceptable treatment, based on Global Perceived Effect scores and the participants' experiences. CONCLUSION: The findings suggest that it is feasible to deliver a full-scale RCT of the SCT intervention for women with PVD. Some changes are suggested to optimize the protocol, such as increasing recruitment sites, change of primary outcome measures, and adding a booster session.

Prepubertal gonadotropin-releasing hormone analog leads to exaggerated behavioral and emotional sex differences in sheep.

In mammals, sex specialization is reflected by differences in brain anatomy and function. Measurable differences are documented in reproductive behavior, cognition, and emotion. We hypothesized that gonadotropin-releasing hormone (GnRH) plays a crucial role in controlling the extent of the brain's sex specificity and that changes in GnRH action during critical periods of brain development, such as puberty, will result in altered sex-specific behavioral and physiological patterns. We blocked puberty in half of the 48 same-sex Scottish mule Texel cross sheep twins with GnRH analog (GnRHa) goserelin acetate every 3 weeks, beginning just before puberty. To determine the effects of GnRHa treatment on sex-specific behavior and emotion regulation in different social contexts, we employed the food acquisition task (FAT) and measurement of heart rate variability (HRV). ANOVA revealed significant sex and sex×treatment interaction effects, suggesting that treated males were more likely to leave their companions to acquire food than untreated, while the opposite effect was observed in females. Concordant results were seen in HRV; treated males displayed higher HRV than untreated, while the reverse pattern was found in females, as shown by significant sex and sex×treatment interaction effects. We conclude that long-term prepubertal GnRHa treatment significantly affected sex-specific brain development, which impacted emotion and behavior regulation in sheep. These results suggest that GnRH is a modulator of cognitive function in the developing brain and that the sexes are differentially affected by GnRH modulation.

Somatocognitive therapy of women with provoked vulvodynia: a pilot study.

BACKGROUND AND AIMS: Provoked vestibulodynia (PVD) is a common persistent pain state among women in the Western world, causing dyspareunia, psychological distress and challenges against fertility. Therapies aimed at relieving pain (physiotherapy) and psychological distress (psychotherapy) are often recommended, sometimes in multimodal combinations. We have previously developed somatocognitive therapy (SCT) as a multimodal intervention, administered by a physiotherapist, to a different group of patients with gynecological pain, i.e. chronic (unprovoked) pelvic pain (CPP, also referred to as low abdominal pain). In a randomized, controlled study this intervention was shown to reduce pain experience and improve motor function or body awareness. Here we present the results of a clinical follow-up pilot study with 30 women with PVD, applying SCT administered by third year bachelor students in physiotherapy. Main outcome was pain experience, secondary outcomes were psychological distress and motor functions of the patients. METHODS: Thirty women diagnosed with PVD were recruited from a tertiary university hospital clinic of gynecology, and included in the follow-up pilot study at an out-patient physiotherapy clinic. Each patient participated in 10-14 therapy sessions over 6 weeks. The students were supervised by an experienced physiotherapist with extensive background in this clinical area, who also performed two clinical sessions with each of the patients at the end of the treatment period. Before therapy, the patients were evaluated for pain experience (visual analogue scale of pain, VAS), psychological distress (Tampa scale of kinesiophobia, TSK) and General Health Questionnaire (GHQ-30) as well as body function (standardized Mensendieck test, SMT). Statistical analyzes were performed by using the average ± standard deviation, statistical significance of changes calculated by means of the t-test. RESULTS: Average pain score before therapy were 7.77 ± 1.98, after 6 weeks of intervention 4.17 ± 2.07 and at 6 months' follow-up 1.66 ± 1.08 (average ± standard deviation), changes being significant below p < 0.01 level. Secondary outcome variables assessing psychological distress and sub optimal motor patterns were also significantly improved. For example, anxiety and depression scores were reduced by approximately 40%, and respiration pattern score improved by almost 80%. CONCLUSIONS: Multimodal somatocognitive therapy reduced levels of pain and psychological distress, and improved motor functions in women with PVD after 6 weeks of interventions. All variables were further improved at 6 months' follow-up. Thus, somatocognitive therapy may be a useful treatment option for patients with PVD. However, there are limitations to this study, since there was no control group, and suboptimal blinding during assessment of the data. IMPLICATIONS: Somatocognitive therapy may be a useful tool when treating PVD patients. More studies, in particular RCTs, should be performed to further evaluate this intervention and corroborate the results from this pilot study.

An Investigation on Bilateral Asymmetry in Electrodermal Activity.

The Multiple Arousal Theory (Picard et al., 2016) was proposed to explain retrospective observations of bilateral differences in electrodermal activities occurring in threat-related high-stake situations. The theory proposes different cortical and subcortical structures to be involved in the processing of various facets of emotional states. Systematic investigations of this effect are still scarce. This study tested the prediction of bilateral electrodermal effects in a controlled laboratory environment where electrodermal activity (EDA) was recorded bilaterally during normal activity and two stress-tasks in 25 healthy volunteers. A visual search stress task with a performance-related staircase algorithm was used, ensuring intersubjectively comparable stress levels across individuals. After completion of the task, a sense of ownership of an attractive price was created and loss aversion introduced to create a high-stake situation. Confirmation of the theory should satisfy the hypothesis of a bilateral difference in EDA between the dominant and non-dominant hand, which is larger during high-stake stressors than during low-stake stressors. The bilateral difference was quantified and compared statistically between the two stress-tasks, revealing no significant difference between them nor any significant difference between the stress tasks and the period of normal activity. Subgroup analysis of only the participants with maximum self-rating of their desire to win the price (n = 7) revealed neither any significant difference between the two tasks nor between the stress-tasks and the period of normal activity. Although the theory was not confirmed by this study, eight cases suggestive of bilateral difference within the recordings were identified and are presented. Because the study is limited in using one of several possible operationalizations of the phenomenon, it is not possible to draw a general conclusion on the theory. Nevertheless, the study might contribute to a better understanding and encourage systematic review and hypothesis development regarding this new theory. Possible explanations and suggestions for future pathways to systematically investigate the Multiple Arousal Theory are discussed.

Continuing improvement of chronic pelvic pain in women after short-term Mensendieck somatocognitive therapy: results of a 1-year follow-up study.

OBJECTIVES: Chronic pelvic pain is a common source of disability among women in the western world. Here we report that 3 months of Mensendieck somatocognitive intervention in chronic pelvic pain patients was followed by continued improvements of outcomes at 1-year follow-up in a randomized, controlled study design. METHODS: Forty women with chronic pelvic pain unexplained by pelvic pathology were randomly assigned to 2 groups: (1) standard gynecologic treatment and (2) gynecologic treatment plus somatocognitive therapy aimed at reducing physical pain by changing posture, movement, and respiration patterns. A standardized Mensendieck test (SMT) of motor function (assessing posture, movement, gait, sitting posture, and respiration), a self-rating questionnaire assessing psychologic distress and general well-being (GHQ-30) and a visual analog score of pain (VAS) were obtained before, after 90 days of treatment and 1 year after inclusion. RESULTS: Patients treated by standard gynecologic treatment/supervision did not improve significantly at 1-year follow-up in any of the test modalities. By contrast, those who in addition received somatocognitive therapy had improved scores for all motor functions and pain, as well as GHQ-30 scores for coping, and anxiety-insomnia-distress. CONCLUSION: Mensendieck somatocognitive therapy combined with standard gynecologic care improves psychologic distress, pain experience, and motor functions of women with chronic pelvic pain better than gynecologic treatment alone. The effect lasted and even further improvement occurred 9 months after treatment.

The Standardised Mensendieck Test as a tool for evaluation of movement quality in patients with nonspecific chronic low back pain.

BACKGROUND AND AIMS: Nonspecific chronic low back pain is a multifactorial biopsychosocial health problem where accurate assessments of pain, function and movement are vital. There are few reliable and valid assessment tools evaluating movement quality, hence the aim was to investigate nonspecific chronic low back pain patients' movement patterns with the Standardised Mensendieck Test. METHODS: Twenty patients (mean age=41, SD=9.02) with nonspecific chronic low back pain were examined with the Standardised Mensendieck Test whilst being videotaped and compared with 20 healthy controls. A physiotherapist, blinded to participant's group belonging, scored Standardised Mensendieck Test videos according to the standardised manual. Associations between movement quality, fear of movement and re(injury) i.e. kinesiophobia and pain intensity were also investigated. RESULTS: Patients scored significantly poorer than the controls in all 5 Standardised Mensendieck Test domains (p<0.001). The biggest difference was observed with regard to movement pattern domain. In women we also found a difference in the respiration pattern domain. CONCLUSIONS: The Standardised Mensendieck Test was able to detect significant differences in quality of movement between patients and healthy controls. These results indicate that the Standardised Mensendieck Test may be a valuable examination tool in assessment and treatment of nonspecific chronic low back pain patients. Further, longitudinal studies should investigate whether poor movement and respiration patterns are important factors in nonspecific chronic low back pain, e.g. as predictors and/or mediators of therapeutic effects.

Pain, psychological distress and motor pattern in women with provoked vestibulodynia (PVD) - symptom characteristics and therapy suggestions.

BACKGROUND AND AIMS: Provoked vestibulodynia (PVD) represent a longstanding pain syndrome that affects large numbers of women worldwide. However, no standardized guidelines for PVD treatment exist. In a cross-sectional pilot study we examined 30 PVD patients on multidimensional parameters including pain, psychological distress and quality of movement, in order to obtain a broader understanding of the somatic and psychological symptoms in PVD, and for the future to develop better interventions. Additionally, we compare the findings to previously published results regarding the same parameters in women with chronic pelvic pain (CPP). METHODS: Thirty women with PVD recruited from a tertiary care university clinic of gynecology were assessed for demographic data, pain intensity (VAS), psychological distress (GHQ-30 and Tampa scale of Kinesophobia) and quality of movement (standardized Mensendieck test, SMT). RESULTS: Average age of the PVD women was 24.7±3.60 years, 60% of them were in permanent relationships, all were nulliparous, none had been subjected to surgical procedures, 100% were working full or part time and 90% were educated to at least undergraduate level. Mean VAS score was 7.77±1.97 (mean±SD), kinesiophobia 24.4±3.95 and anxiety domain of GHQ-30 9.73±4.06. SMT scores were particularly low for the domains of respiration and gait (less than 50% of optimal scores). CONCLUSIONS: PVD women display reduced quality of movement, especially for gait and respiration patterns, increased level of anxiety and high average pain scores. These findings are similar to what we have previously reported in CPP patients. However, in contrast to CPP group, PVD women are on average younger, have higher work participation, higher education level and have not been subjected to surgical procedures. IMPLICATIONS: Since PVD women display similar, although somewhat less severe, symptom profile than CPP, we suggest that a multidimensional approach to treatment, such as "somatocognitive therapy" should be investigated in this group as it has previously been shown to be promising in treatment of CPP.

Posture, movement patterns, and body awareness in women with chronic pelvic pain.

OBJECTIVE: Chronic pelvic pain (CPP) is a common cause of infirmity but is still poorly understood. We studied the clinical characteristics, including body awareness, of 60 women with this diagnosis compared to those of healthy controls in an effort to understand its pathophysiology and to develop a more efficient treatment protocol. METHODS: After prior gynecologic and psychometric evaluation, the women were examined with the Standardized Mensendieck Test to evaluate posture and movement patterns. Pain history and pain score were obtained, and patterns of muscular density, elasticity, and tenderness were determined by palpation. The body awareness of patients was assessed through clinical evaluation. RESULTS: Seventy percent of the patients had a history of trauma or infection of the genitourinary region. The average pain score (+/-S.D.) on a scale from 0 to 10 was 6.01+/-1.60. Nearly all patients had a dissociative pattern, with a lack of contact and control of large body regions. All scores for posture and movement patterns were significantly worse in patients than in healthy women. CONCLUSION: A specific pattern of pain, posture, movement, muscle pathology, and reduced awareness of one's own body was found in women with CPP. These findings may increase our understanding of, and may point toward new treatment strategies for, this disease.

Cognitive, Emotional, and Psychosocial Functioning of Girls Treated with Pharmacological Puberty Blockage for Idiopathic Central Precocious Puberty.

Central precocious puberty (CPP) develops due to premature activation of the hypothalamic-pituitary-gonadal (HPG) axis, resulting in early pubertal changes and rapid bone maturation. CPP is associated with lower adult height and increased risk for development of psychological problems. Standard treatment of CPP is based on postponement of pubertal development by blockade of the HPG axis with gonadotropin releasing hormone analogs (GnRHa) leading to abolition of gonadal sex hormones synthesis. Whereas the hormonal and auxological effects of GnRHa are well-researched, there is a lack of knowledge whether GnRHa treatment influences psychological functioning of treated children, despite the fact that prevention of psychological problems is used as one of the main reasons for treatment initiation. In the present study we seek to address this issue by exploring differences in cognitive function, behavior, emotional reactivity, and psychosocial problems between GnRHa treated CPP girls and age-matched controls. Fifteen girls with idiopathic CPP; median age 10.4 years, treated with slow-release GnRHa (triptorelin acetate-Decapeptyl SR® 11.25) and 15 age-matched controls, were assessed with a comprehensive test battery consisting of paper and pencil tests, computerized tasks, behavioral paradigms, heart rate variability, and questionnaires filled in by the children's parents. Both groups showed very similar scores with regard to cognitive performance, behavioral and psychosocial problems. Compared to controls, treated girls displayed significantly higher emotional reactivity (p = 0.016; Cohen's d = 1.04) on one of the two emotional reactivity task conditions. Unexpectedly, the CPP group showed significantly lower resting heart rates than the controls (p = 0.004; Cohen's d = 1.03); lower heart rate was associated with longer treatment duration (r = -0.582, p = 0.037). The results suggest that GnRHa treated CPP girls do not differ in their cognitive or psychosocial functioning from age matched controls. However, they might process emotional stimuli differently. The unexpected finding of lower heart rate that was associated with longer duration of the treatment should be further explored by methods appropriate for assessment of cardiac health.

Beyond expectation: a case for nonpersonal contextual factors in a more comprehensive approach to the placebo effect and the contribution of environmental psychology.

Creating an optimized health care environment to maximize the probability and magnitude of placebo effects draws on a number of well-researched mechanisms such as the patient's positive expectation toward treatment outcome. Patient-centered communication styles influence expectations and can thus be considered as a form of supplemental treatment. Unconsciously processed contextual triggering and facilitating placebo effects are omnipresent in clinical settings as well as in all other social and physical environments. Contextual cues in both the social and physical domain exert influences on the recipient's emotional state and recreational experiences. While the majority of research focuses on improving the patients' expectations, classical conditioning effects of nonsocial contextual factors have been largely neglected in discussions on practical implementation of placebo-enhancing environments. Built on the empirically well-supported argument that conditioning processes act as a powerful tool to mobilize self-healing resources just as verbally induced expectations do, we argue for a stronger consideration of the effects of permanent, nonsocial and nonverbal environmental contexts. Environmental psychology is a new field of research within the psychological domain and offers a toolbox of opportunities for medical psychological research and health care practitioners to improve the treatment outcomes and benefits of health care environments.

Sex-specific development of spatial orientation is independent of peripubertal gonadal steroids.

Prenatal exposure to androgens has been shown to modulate brain development, resulting in changed behavioral attitudes, sexual orientation and cognitive functions, including processing of spatial information. Whether later changes in gonadotropic hormones during puberty induce further organizational effects within the brain is still insufficiently understood. The purpose of this study was to assess development of spatial orientation before and after the time of normal pubertal development, in an ovine model where half of the animals did not undergo typical reproductive maturation due to the pharmacological blockade of gonadotropin releasing hormone receptor (GnRHR) signaling. The study formed part of a larger trial and utilized 46 pairs of same sex Scottish Mule Texel Cross twins (22 female and 24 male). One twin remained untreated throughout (control) while the other received a subcutaneous GnRH agonist (GnRHa: Goserelin-Acetate) implant every fourth week. GnRHa treatment began at eight and 28 weeks of age, in males and females respectively, because the timing of the pubertal transition is sexually differentiated in sheep as it is in humans. Spatial orientation was assessed at three different time points: eight weeks of age, before puberty and treatment in both sexes; 28 weeks of age, after 20 weeks GnRHa treatment in males and before puberty and GnRHa treatment in females; and at 48 weeks of age, which is after the normal time of the pubertal transition in both sexes. Spatial orientation was tested in a spatial maze with traverse time as the main outcome measure. GnRHa treatment did not affect spatial maze performance as no significant differences in traverse time between treated and untreated animals were observed at any time-point. Adolescent females (48 weeks of age) traversed the maze significantly faster than adolescent males, whereas no sex differences in traverse time were seen at earlier developmental stages (eight and 28 weeks). Development of sex differences in spatial orientation was independent of exposure to pubertal hormones since puberty-blocked and control animals both showed the same pattern of spatial maze performance. This result demonstrates the prenatal nature of spatial orientation development. Furthermore, the unexpected finding that female animals outperformed males in the spatial orientation task, underscores the importance of the testing context in spatial orientation experiments.

Peri-pubertal gonadotropin-releasing hormone analog treatment affects hippocampus gene expression without changing spatial orientation in young sheep.

BACKGROUND: Normal brain maturation is the result of molecular changes that can be modulated by endocrine variables associated with brain plasticity and results in sex- and age specific changes in cognitive performance. Using a sheep model, we have previously shown that peri-pubertal pharmacological blockade of gonadotropin releasing hormone (GnRH) receptors results in increased sex-differences in cognitive executive function and emotional control. In this study we explore effects of this treatment regime on hippocampal gene expression and spatial orientation. METHODS: The study was conducted with 30 same-sex twin lambs, half of which were treated with the GnRH analog (GnRHa) goserelin acetate every 4th week, beginning before puberty, until 50 weeks of age. Animals were tested in their spatial orientation ability at 48 weeks of age. Quantitative real time PCR analysis was conducted to examine effects of treatment on the expression of genes associated with synaptic plasticity and endocrine signaling. RESULTS: GnRHa treatment was associated with significant sex- and hemisphere specific changes in mRNA expression for some of the genes studied. The treatment had no significant effect on spatial orientation. However, there was a tendency that females performed better than males in spatial orientation. CONCLUSION: Our results indicate that GnRH directly and/or indirectly, is involved in the regulation of sex- and side-specific expression patterns of genes. Hence, these results should be considered when long-term peri-pubertal GnRHa treatment is used in children.
