When shared pain is not half the pain: enhanced central nervous system processing and verbal reports of pain in the presence of a solicitous spouse

Differential effects of everyday-life social support on chronic pain

BACKGROUND

Social support is a multidimensional construct encompassing emotional support as well as pain-focused care and attention, also known as solicitous support. One the one hand, social support is widely believed to positively influence pain symptoms, their intensity, and the ability to cope and influence pain. On the other hand, social support can be negative if it conflicts with the patient's needs or even causes discomfort. How different types of social support influence pain is not very well understood especially because most of the present research originates from laboratory studies, raising uncertainties about its generalizability to the everyday life of individuals with chronic pain.

METHODS

Here, we tested the effects of emotional, solicitous, and negative social support on pain intensity cross-sectionally in everyday life. We collected data from 20 patients with acute complex regional pain syndrome using a smartphone-based Ecological Momentary Assessment with up to 30 survey prompts over a period of five consecutive days.

RESULTS

Our results showed that solicitous social support decreased pain, in particular in male patients. Emotional support was beneficial on pain in women but not in men.

CONCLUSIONS

Taken together, these findings highlight the differential effects of social support in every-day life on chronic pain.

Endometriosis: patient-doctor communication and psychological counselling

The fact that endometriosis is one of the most frequent gynaecological disorders in women and girls is gradually attracting greater public and political attention. There is also substantial awareness of the disorder among German gynaecologists, albeit without sufficient "equipment" for discussing the condition with patients and providing psychological counselling. This article offers hands-on proposals for medical counselling and the discussion of relevant issues, as well as other practical tips and suggested verbalisations for use by women suffering from endometriosis (and their partners). These practical recommendations will certainly help to improve the doctor-patient relationship in the case of endometriosis. The resources mentioned below (guidebooks, websites) focus on German-language offerings only.

The impact of the social context on the development of secondary hyperalgesia: an experimental study

ABSTRACT

Social support has been shown to reduce pain ratings and physiological responses to acute pain stimuli. Furthermore, this relationship is moderated by adult attachment styles. However, these effects have not been characterized in experimentally induced symptoms of chronic pain, such as secondary hyperalgesia (SH) which is characterized by an increased sensitivity of the skin surrounding an injury. We aimed to examine whether social support by handholding from a romantic partner can attenuate the development of experimentally induced SH. Thirty-seven women, along with their partners, participated in 2 experimental sessions 1 week apart. In both sessions, SH was induced using an electrical stimulation protocol. In the support condition, the partner was seated across from the participant holding the participant's hand during the electrical stimulation, whereas in the alone condition, the participant went through the stimulation alone. Heart rate variability was measured for both the participant as well as the partner before, during, and after the stimulation. We found that the width of the area of hyperalgesia was significantly smaller in the support condition. Attachment styles did not moderate this effect of social support on the area width. Increasing attachment avoidance was associated with both a smaller width of hyperalgesia and a smaller increase in the sensitivity on the stimulated arm. For the first time, we show that social support can attenuate the development of secondary hyperalgesia and that attachment avoidance may be associated with an attenuated development of secondary hyperalgesia.

Effect of Regular Electrotherapy on Spinal Flexibility and Pain Sensitivity in Patients with Chronic Non-Specific Neck Pain and Low Back Pain: A Randomized Controlled Double-Blinded Pilot Trial

Background and Objectives: Chronic neck pain and low back pain are common conditions in high-income countries leading to social and medical problems such as invalidity and decreased quality of life. The aim of this study was to investigate the effect of supra-threshold electrotherapy on pain level, subjective feeling of disability, and spinal mobility in patients with chronic pain in the spinal cord. Materials and Methods: 11 men and 24 women with a mean age of 49 years were randomly divided into three groups: group 1, "therapy": supra-threshold electrotherapy was applied on the whole back after electrical calibration; group 2, "control": electrical calibration without successive electrotherapy; group 3, "control of control": no stimulation. Sessions were performed once a week and six times in total, each lasting 30 min. The numeric pain rating scale (NRS), cervical and lumbar range of motion (ROM), as well as disability in daily live were investigated before and after the sessions using questionnaires (Neck Disability Index, Roland Morris Questionnaire, Short-form Mc Gill Pain Questionnaire (SF-MPQ)). Results: Spinal mobility improved significantly in the lumbar anteflexion (baseline mean, 20.34 ± SD 1.46; post session mean, 21.43 ± SD 1.95; p = 0.003) and retroflexion (baseline mean, 13.68 ± SD 1.46; post session mean, 12.05 ± SD 1.37; p = 0.006) in the group receiving electrotherapy. Pain levels measured by the NRS and disability-questionnaire scores did not differ significantly before and after treatment in any of the groups. Conclusions: Our data indicate that regular supra-threshold electrotherapy for six times has a positive effect on lumbar flexibility in chronic neck pain and low back pain patients, whereas pain sensation or subjective feeling of disability remained unchanged.

Friend or Foe? A Thematic Analysis of Adult Friendships and Chronic Pain Adjustment

BACKGROUND

Chronic pain is a worldwide public health challenge. Despite chronic pain having biopsychosocial dimensions, its social contexts are less investigated. Although current evidence shows that chronic pain shapes and is shaped by interactions with romantic partners, research about friendships and chronic pain is scarce, and mostly focused on adolescents.

AIM

Drawing upon theories on friendship and social support, this study aimed to investigate the role of adult friendships on chronic pain adjustment and, the effect of chronic pain on adult friendships.

METHODS

This study drew upon a qualitative descriptive methodology. Sixteen adults with primary or secondary (non-cancer) chronic pain participated in individual semi-structured interviews, conducted using voice over internet protocol applications. Data analysis was guided by Clarke and Brown's guidelines for thematic analysis.

RESULTS

The analysis of participants' (87.5% women; M_age = 43 years) stories revealed two themes. The first captured how friends promote/hinder adjustment to chronic pain by being: (1) (un)available and providing (un)needed support; and (2) (not)accepting and (not)accommodating to support life engagement. The second captured the negative effect of chronic pain on both parties' attitudes and behaviors towards the relationship, leading to smaller and more homogeneous friendship networks.

CONCLUSIONS

This study stresses the relevance of including adult friends in interventions to reduce the negative effect of chronic pain on friendships, harnessing their power to promote chronic pain adjustment. The findings bring new insights on a topic that has rarely been investigated in the pain field, hence pointing out innovative directions for future research and practice.

[Psychotherapeutic Work with Relatives and Couples in Selected Mental and Physical Illnesses]

A physical or mental illness affects not only patients but also their family environment. The immediate (caring) relatives are of particular importance in coping with the illness. However, they are often overlooked as invisible patients in the second row. Using selected diseases such as cancer, dementia and pain as examples, the following article will illustrate the special importance of working with relatives and couples. The focus in this article is on adult relatives. The group of children as relatives requires separate consideration.

The association of spouse interactions and emotional learning in interference related to chronic back pain

Social interactions affect individual behaviours, preferences, and attitudes. This is also critical in the context of experiencing pain and expressing pain behaviours, and may relate to learned emotional responses. In this respect, individual variability in the medial prefrontal cortex (mPFC), which is involved in adjusting an organism's behaviour to its environment by evaluating and interpreting information within the context of past experiences, is important. It is critical for selecting suitable behavioural responses within a social environment and may reinforce maladaptation in chronic pain. In our study, we used brain imaging during appetitive and aversive pavlovian conditioning in persons with chronic back pain (CBP), subacute back pain (SABP), and healthy controls (HC), together with information on spouse responses to pain behaviours. We also examined the relationship of these responses with pain-related interference in the patients. Our findings yielded a significant negative association between mPFC responses to appetitive and aversive learning in CBP. We also observed a significant negative association for mPFC responses during aversive learning and distracting spouse responses, and a significant positive association between mPFC responses during appetitive learning and solicitous spouse responses in CBP. Both significantly predicted pain-related interference in the CBP group (explained variance up to 53%). Significant associations were not found for SABP or HC. Our findings support an association between appetitive and aversive pavlovian learning, related brain circuits and spouse responses to pain in CBP, where appetitive and aversive learning processes seem to be differentially involved. This can inform prevention and early intervention in a mechanistic approach.
