The impact of spinal cord injury on sexual function: concerns of the general population

Potential role of hippocampal neurogenesis in spinal cord injury induced post-trauma depression

It has been reported both in clinic and rodent models that beyond spinal cord injury directly induced symptoms, such as paralysis, neuropathic pain, bladder/bowel dysfunction, and loss of sexual function, there are a variety of secondary complications, including memory loss, cognitive decline, depression, and Alzheimer's disease. The large-scale longitudinal population-based studies indicate that post-trauma depression is highly prevalent in spinal cord injury patients. Yet, few basic studies have been conducted to address the potential molecular mechanisms. One of possible factors underlying the depression is the reduction of adult hippocampal neurogenesis which may come from less physical activity, social isolation, chronic pain, and elevated neuroinflammation after spinal cord injury. However, there is no clear consensus yet. In this review, we will first summarize the alteration of hippocampal neurogenesis post-spinal cord injury. Then, we will discuss possible mechanisms underlie this important spinal cord injury consequence. Finally, we will outline the potential therapeutic options aimed at enhancing hippocampal neurogenesis to ameliorate depression.

[Importance of neuro-urological care in patients with spinal cord injuries/diseases]

Integrity, control and regulation of the urinary tract are subject to a complex neuronal regulation, in which portions of the sympathetic, parasympathetic and somatic nervous system are involved. The spinal cord plays a central role in regulation and serves as a transmitter for the motor and sensory pathways. Bladder dysfunction followed by renal dysfunction was the most frequent cause of death in patients with spinal cord injuries/diseases (paraplegia) as recently as half a decade ago. Thanks mainly to diagnostic and therapeutic advances made in neuro-urology, urological problems are no longer life-limiting. A vital role is played not only by the actual function of the urinary tract but also by the complex interactions in patients living with paraplegia. Issues such undertreated hyperactivity of the detrusor muscle with autonomous dysregulation, incontinence with secondary skin changes, or insufficient hand function to perform intermittent catheterisation must be evaluated in an interdisciplinary approach. Spinal cord injury/disease implies numerous functional disorders and secondary impairments of the organism. In addition to bladder function, sexual dysfunction also plays a crucial role. Especially in younger patients who sustain paraplegia before or during the family planning phase, this disruption and limitation is an essential reason for reduced quality of life. Neurogenic intestinal function plays an additional crucial role with regard to quality of life and management of everyday life. In recent years, the range of neuro-urological topics has expanded significantly. The focus of our work shifted from being merely on the urinary tract and urodynamics. In particular, the diagnostic investigation and treatment of neurogenic intestinal dysfunction is increasingly in the hands of neuro-urologists. The complex presentation of paraplegia involves an interaction of bladder, intestinal and sexual dysfunction in a way that these influence one another. Therefore, the sustained care and re-integration of these patients essentially includes lifelong and regular neuro-urological care in a paraplegia centre. Last but not least, it is exactly these neuro-urological topics such as urinary tract infections, urinary and intestinal incontinence and faecal impaction, which most commonly lead to re-hospitalisation.

Sexual Activity in Adults with Pediatric-Onset Spinal Cord Injury: Injury, Demographic, and Lifestyle Factors

Background

Sexual development is a complex process of understanding oneself as a sexual being. Youth with spinal cord injury (SCI) navigate the typical phases of sexual development along with the physical and psychological sequelae of an SCI. As youth with SCI progress from adolescence to emerging adulthood, sexual activity-physical intimacy and sexual intercourse-is an important milestone.

Objectives

The aims of the study were to (1) describe frequency of physical intimacy among adults with pediatric-onset SCI and (2) identify injury, demographic, and lifestyle factors that predict frequency of physical intimacy.

Methods

Adults with pediatric-onset SCI who were former patients within a North American pediatric hospital system (N = 277) completed a structured telephone interview that included medical and sociodemographic information and standardized measures of psychological functioning. Participants rated physical intimacy and sexual intercourse frequency on a 5-point Likert scale, with a response of monthly, weekly, or daily classified as regular frequency and never or yearly as irregular frequency. Bivariate and multivariate analyses were conducted with physical intimacy frequency as the primary outcome.

Results

Of the participants, 55% engaged in physical intimacy and 49% engaged in sexual intercourse with regular frequency. In logistic regression analyses, living independently of parents, being married, and higher perceived social integration increased likelihood of regular frequency of physical intimacy. Injury severity and secondary medical complications were not significant independent predictors of frequency of physical intimacy.

Conclusion

Half of adults with pediatric-onset SCI engage in regular physical intimacy; this is below the estimates for the general population. Psychosocial factors are stronger contributors to physical intimacy frequency than SCI-related factors. Health care providers and researchers should focus on barriers to social integration and development of social relationships as factors that influence physical intimacy in this population.

Functional ultrasound imaging of the human spinal cord

Utilizing the first in-human functional ultrasound imaging (fUSI) of the spinal cord, we demonstrate the integration of spinal functional responses to electrical stimulation. We record and characterize the hemodynamic responses of the spinal cord to a neuromodulatory intervention commonly used for treating pain and increasingly used for the restoration of sensorimotor and autonomic function. We found that the hemodynamic response to stimulation reflects a spatiotemporal modulation of the spinal cord circuitry not previously recognized. Our analytical capability offers a mechanism to assess blood flow changes with a new level of spatial and temporal precision in vivo and demonstrates that fUSI can decode the functional state of spinal networks in a single trial, which is of fundamental importance for developing real-time closed-loop neuromodulation systems. This work is a critical step toward developing a vital technique to study spinal cord function and effects of clinical neuromodulation.

Adaptations to adult attachment and intimacy following spinal cord injury: a systematic review

PURPOSE

Experiencing spinal cord injury (SCI) can be life-changing for individuals and their families. Previous reviews have focused on coping and psychological adjustment, sexual function and sexuality, or factors facilitating or impeding interpersonal relationships after SCI. However, there is a very little synthesis of research focusing on changes to adult attachment and emotional intimacy post-SCI. This review aims to examine the mechanisms of change in adult attachment and intimacy in romantic relationships following SCI.

MATERIALS AND METHODS

Four online databases (Psycinfo, Medline, CINAHL, and Scopus) were searched for qualitative papers concerning romantic relationships, attachments, and intimacy post-SCI. Sixteen of the 692 papers met the inclusion criteria. These were quality assessed and analysed using meta-ethnography.

RESULTS

Three main themes emerged from the analysis: (a) strengthening and maintaining adult attachment; (b) changes in roles; and (c) changing views of intimacy.

CONCLUSION

Many couples face significant changes to adult attachment and intimacy following SCI. Systematic ethnographic analysis of their negotiations enabled the identification of underlying relational processes and adaptation strategies associated with changes to inter-dependence, communication, role revision, and re-definition of intimacy. The findings indicate that healthcare providers should assess and respond to challenges faced by couples post-SCI using evidence consistent with adult attachment theory.

Looking Beyond the Chair: Psycho-Perceptual Predictors of Sexual Distress and Sexual Satisfaction in Individuals with Spinal Cord Injury

Despite a large body of biomedical research, little is known about the psychological and perceptual predictors of sexual satisfaction (SS) and sexual distress (SD) post spinal cord injury (SCI). Guided by a bio-psycho-perceptual framework, this cross-sectional research aimed at assessing SS and SD in a large SCI sample using validated patient-reported outcome measures (PROM). Significant correlates and predictors of SS and SD were also identified. Ninety-one men and women with SCI completed PROMs of SS and SD, as well as psychological (mood, sexual and body esteem) and perceptual (interoceptive awareness, trait mindfulness, sexual mindfulness) factors. Neurological profiles were also assessed, along with experience of orgasm. Correlates of SS and SD were first identified using Pearson's correlations, then multiple hierarchical regression models were computed to isolate predictors. Orgasm experience and psychological factors emerged as moderate correlates of both SS and SD, while neurological factors did not. Interoceptive awareness and trait mindfulness showed weak associations with SD and none with SS. Among the tested predictors, experience of orgasm emerged as the strongest for SS (β = -.29, p < .01), followed by mood, which predicted SS and SD. Sexual and body esteem was predictive of SD only. In sexually active participants, sexual mindfulness predicted both SS (β = 0.55, p < .001) and SD (β = -0.56, p < .001) above and beyond all other variables. This study reveals unique aspects of SS and SD postinjury and supports further consideration of psychological and perceptual dimensions of SCI sexuality in rehabilitation research.

Consequences of spinal cord injury on the sympathetic nervous system

Spinal cord injury (SCI) damages multiple structures at the lesion site, including ascending, descending, and propriospinal axons; interrupting the conduction of information up and down the spinal cord. Additionally, axons associated with the autonomic nervous system that control involuntary physiological functions course through the spinal cord. Moreover, sympathetic, and parasympathetic preganglionic neurons reside in the spinal cord. Thus, depending on the level of an SCI, autonomic function can be greatly impacted by the trauma resulting in dysfunction of various organs. For example, SCI can lead to dysregulation of a variety of organs, such as the pineal gland, the heart and vasculature, lungs, spleen, kidneys, and bladder. Indeed, it is becoming more apparent that many disorders that negatively affect quality-of-life for SCI individuals have a basis in dysregulation of the sympathetic nervous system. Here, we will review how SCI impacts the sympathetic nervous system and how that negatively impacts target organs that receive sympathetic innervation. A deeper understanding of this may offer potential therapeutic insight into how to improve health and quality-of-life for those living with SCI.

Optimized multi-echo gradient-echo magnetic resonance imaging for gray and white matter segmentation in the lumbosacral cord at 3 T

Atrophy in the spinal cord (SC), gray (GM) and white matter (WM) is typically measured in-vivo by image segmentation on multi-echo gradient-echo magnetic resonance images. The aim of this study was to establish an acquisition and analysis protocol for optimal SC and GM segmentation in the lumbosacral cord at 3 T. Ten healthy volunteers underwent imaging of the lumbosacral cord using a 3D spoiled multi-echo gradient-echo sequence (Siemens FLASH, with 5 echoes and 8 repetitions) on a Siemens Prisma 3 T scanner. Optimal numbers of successive echoes and signal averages were investigated comparing signal-to-noise (SNR) and contrast-to-noise ratio (CNR) values as well as qualitative ratings for segmentability by experts. The combination of 5 successive echoes yielded the highest CNR between WM and cerebrospinal fluid and the highest rating for SC segmentability. The combination of 3 and 4 successive echoes yielded the highest CNR between GM and WM and the highest rating for GM segmentability in the lumbosacral enlargement and conus medullaris, respectively. For segmenting the SC and GM in the same image, we suggest combining 3 successive echoes. For SC or GM segmentation only, we recommend combining 5 or 3 successive echoes, respectively. Six signal averages yielded good contrast for reliable SC and GM segmentation in all subjects. Clinical applications could benefit from these recommendations as they allow for accurate SC and GM segmentation in the lumbosacral cord.

Australian arm of the International Spinal Cord Injury (Aus-InSCI) Community Survey: 2. Understanding the lived experience in people with spinal cord injury

STUDY DESIGN

Cross-sectional survey.

OBJECTIVES

To identify common problems across key domains of functioning, health and wellbeing, as well as evaluate self-reported quality of life (QoL) by people with SCI, examining differences by age, gender, injury characteristics and level of mobility.

SETTING

Data from four state-wide SCI clinical services, one government insurance agency and three not-for-profit consumer organisations.

METHODS

Participants were 18 years or over with SCI and at least 12 months post-injury, recruited between Mar'18 and Jan'19. The Aus-InSCI questionnaire comprised 193 questions, including socio-demographics, SCI characteristics, body functions and structures, activities and participation, environmental and personal factors, and appraisal of health and well-being. General linear model was used to examine differences in functioning and QoL.

RESULTS

Participants (mean age 57 years, range 19-94 years) with tetraplegia and/or complete injuries had more health problems, activity/participation problems and environmental barriers. However, self-rated overall QoL did not differ for injury level or completeness. Participants with more recent injuries exhibited lower independence levels, more mental health problems and poorer satisfaction with self and their living conditions. Major activity/participation problems related to intimate relationships and accessing public transportation. Less than half of the working age population were engaged in paid work. The top two environmental barriers frequently related to accessing public places or homes and unfavourable climatic conditions.

CONCLUSIONS

This large, comprehensive community survey draws a detailed picture of the lived experience of people with SCI in Australia, identifying priority needs, gaps in services and barriers to achieving a full and satisfying life.

Experiences of patients and their partners with sexual problems after spinal cord injury: A phenomenological qualitative study

Objective: This study aimed to examine the experiences of patients and their partners about their sexual lives after Spinal Cord Injury (SCI).Design: This qualitative study was based on Heidegger's hermeneutic phenomenological approach.Setting: The Physical Medicine and Rehabilitation Outpatient Clinic of a city hospital in the Central Anatolia Region in Turkey.Participants: The study consisted of seven female and six male patients with spinal cord injury and their partners.Outcome measures: The textual analysis was carried out in three stages: (1) a naive reading, (2) a structural analysis, and (3) a comprehensive understanding of the text including a discussion. The sample size was calculated by using the criterion sampling technique.Results: As a result of the in-depth interviews with individuals with SCI about their sexual experiences, five themes were derived: (1) first confrontation with SCI, (2) experienced sexual problems, (3) coping, (4) partners' views on sexual problems, and (5) other people.Conclusion: It was found that the sex life of individuals with SCI was negatively affected, they were left helpless in dealing with their problems, and that some patients had difficulties in coping with this condition.

Measuring Sexual Performance: Development and Psychometric Properties of the Sexual Performance Questionnaire in Iranian People with Spinal Cord Injury

Sexual performance refers to activities served by sexual capacity and motivation. As a culturally sensitive issue, to date the scalar invariance of sexual performance has not been examined for Iranians with spinal cord injuries (SCIs). Aim: To develop and assess properties of an instrument evaluating sexual performance of an Iranian population with SCIs., in Brain and Spinal Cord Injury Research Center (BASIR), Neuroscience Institute, Tehran University of Medical Sciences, Tehran, Iran. Using multi-modal methods, we developed and assessed the Sexual Performance Questionnaire (SPQ). This included collecting expert opinions; engaging with patients with SCI referred to BASIR; pilot testing to assess the scale; and a formal investigation. Participants (men = 156, women = 58) completed the SPQ. Internal consistency and reliability were measured using Cronbach's α coefficient. Content and face validity were examined by academic experts. Construct validity was assessed by examining convergent and discriminant validity. Finally, exploratory factor analysis was used to extract the factor structure of the questionnaire. The Cronbach's α coefficient was 0.77. There was a significant (p = 0.04) correlation (r = - 0.23) between the SPQ score and age. Those with a partner scored higher (p = 0.001). We found three components: Spouse as initiator, self-initiation, and genital-oriented sex which accounted for 59% of the observed variance. The face and content validity was approved by an expert committee. The development and application of the 13-item SPQ provides a thorough understanding of sexual performance amongst persons with SCI. It facilitates the development of efficient sexual rehabilitation interventions and SCI-specific sexuality education programs.

Quality of Life and Activities of Daily Living among Patients with Complete Cervical Spinal Cord Injury and Surgical Treatment in Vietnam

Spinal cord injury (SCI) is defined as temporary or permanent changes in spinal cord function and reflex activity. The objective of this study is to evaluate health-related quality of life (HRQoL) and activities of daily living (ADL) among postoperative surgery patients with complete cervical SCI in Vietnam and to explore the factors associated with these indices. A cross-sectional study was conducted on 88 adults in Vietnam from June 2018 to June 2019. The EQ-5D-5L, ADL, and instrumental activities of daily living (IADL) were applied. Multivariate Tobit regression was adopted to determine factors that were associated with HRQOL, ADL, and IADL. Results: Participants who were in American Spinal Cord Injury Association (ASIA) scale group A (ASIA-A) had the lowest ADL, IADL index, and HRQOL score (p < 0.001). HRQoL and ADL were affected by health insurance coverage, occupation, type of fracture, and IADL. Meanwhile, IADL was significantly associated with living areas and ASIA. Low HRQoL among patients suffering from SCI was observed. Attention should be given to outcomes related to a disability during clinical treatment and should be treated effectively in the recovery.

An evaluation of the factors that affect the sexual satisfaction of people with spinal cord injuries

Objective: To evaluate the relationships between the variables that affect the sexual satisfaction of patients with spinal cord injuries.Design: Descriptive and cross-sectional survey.Setting: The physical medicine and rehabilitation outpatient clinic of a university hospital in Turkey.Participants: This study was performed from July to December2018. It included 103 patients with spinal cord injuries.Outcome Measures: The data were collected using an introductory information form, the American Spinal Injury Association Impairment Scale and the Golombok Rust Inventory of Sexual Satisfaction. Data were evaluated using the chi-square test, the Mann-Whitney U test, the Kruskal-Wallis test and linear regression.Results: The total mean scores on the Golombok Rust Inventory of Sexual Satisfaction were 40.2 ± 21.6 for males and 44.9 ± 18.1 for females. According to the linear regression analysis, model VII presented the best results of the relationship between physiological and psychological determinants that affect the sexual satisfaction of patients with spinal cord injuries. Model VII consisted of the variables of ASIA A and B scores, age, injury due to falling from height, being a housewife, and thinking of being unable to reach future goals. These explained 75.4% of the variation in sexual satisfaction scores.Conclusion: The participants' mean scores on the Golombok Rust Inventory of Sexual Satisfaction were found to be affected by various variables. A significant relationship between their mean scores on the American Spinal Injury Association (ASIA) Impairment Scale and the Golombok Rust Inventory of Sexual Satisfaction was determined.

Spinal Cord Injury Causes Reduction of Galanin and Gastrin Releasing Peptide mRNA Expression in the Spinal Ejaculation Generator of Male Rats

Spinal cord injury (SCI) in men is commonly associated with sexual dysfunction, including anejaculation, and chronic mid-thoracic contusion injury in male rats also impairs ejaculatory reflexes. Ejaculation is controlled by a spinal ejaculation generator consisting of a population of lumbar spinothalamic (LSt) neurons that control ejaculation through release of four neuropeptides including galanin and gastrin releasing peptide (GRP) onto lumbar and sacral autonomic and motor nuclei. It was recently demonstrated that spinal contusion injury in male rats caused reduction of GRP-immunoreactivity, but not galanin-immunoreactivity in LSt cells, indicative of reduced GRP peptide levels, but inconclusive results for galanin. The current study further tests the hypothesis that contusion injury causes a disruption of GRP and galanin mRNA in LSt cells. Male rats received mid-thoracic contusion injury and galanin and GRP mRNA were visualized 8 weeks later in the lumbar spinal cord using fluorescent in situ hybridization. Spinal cord injury significantly reduced GRP and galanin mRNA in LSt cells. Galanin expression was higher in LSt cells compared to GRP. However, expression of the two transcripts were positively correlated in LSt cells in both sham and SCI animals, suggesting that expression for the two neuropeptides may be co-regulated. Immunofluorescent visualization of galanin and GRP peptides demonstrated a significant reduction in GRP-immunoreactivity, but not galanin in LSt cells, confirming the previous observations. In conclusion, SCI reduced GRP and galanin expression in LSt cells with an apparent greater impact on GRP peptide levels. GRP and galanin are both essential for triggering ejaculation and thus such reduction may contribute to ejaculatory dysfunction following SCI in rats.

Sexual dysfunction in women with spinal cord injury living in Greece

STUDY DESIGN

Cross-sectional study.

OBJECTIVES

To provide data on the rates of sexual dysfunction (SD) among the Greek spinal cord injury (SCI) women and to investigate any association with demographic and clinical variables.

SETTING

Greek territory.

METHODS

Our sample was enrolled from rehabilitation institutes throughout Greece and included 30 women with SCI living in the community for at least 1 year after the primary inpatient rehabilitation program. They were assessed for SD using the Female Sexual Function Index (FSFI). Pearson's test was performed to examine the correlation of SD with clinical-demographic parameters as defined by specific questionnaires: Satisfaction With Life Scale (SWLS), World Health Organization Quality of Life-BREF (WHOQOL-BREF), Spinal Cord Independence Measure (SCIM), Patient Health Questionnaire (PHQ-9), Craig Handicap Assessment and Reporting Technique (CHART).

RESULTS

SD was revealed in 63.3% of the study participants. The mean FSFI score was 14.4. Pearson's analysis showed that age was negatively correlated with FSFI scores (p = 0.006), while pain had a negative impact only on desire scores (p = 0.04). FSFI scores were negatively correlated with PHQ-9 (p = 0.04), while there was a positive correlation with SWLS (p = 0.003), SCIM (p = 0.013), and specific domains of WHOQOL-BREF (psychological, relations, environment), and CHART (mobility, social integration).

CONCLUSIONS

The rate of SD (63.3%) generally agrees with the findings of high rates in most of the literature, although it is rather lower, in comparison to other populations. Old age and depressive symptoms were the major identified determinants of SD.

Erectile Dysfunction Is the Main Correlate of Depression in Men with Chronic Spinal Cord Injury

Depression is the most prevalent psychological issue after a spinal cord injury (SCI) and is associated with noticeable disability, mortality and health expenditure. As SCI mainly occurs in sexually active men at a young age, and can lead to them suffering from an organic neurogenic erectile dysfunction (ED), we supposed that ED could be a major correlate of depressive status in men with SCI. As documented by a Beck Depression Inventory-II (BDI-II) score ≥14, depression was reported in 17 out of 57 men with a chronic SCI (29.8%). They exhibited a significantly higher prevalence of ED and a more severe bowel and bladder dysfunction when compared to the group without depression. At the multiple logistic regression analysis, depression showed a significant independent association with ED (OR = 19.0, 95% CI: 3.1, 203.3; p = 0.004) and, to a lesser extent, with a severe impairment of bowel and bladder function (OR = 0.84; 95% CI: 0.72, 0.94; p = 0.01). Depression was observed in 43.7% of men with ED and only in 12.0% of those without ED (p = 0.002). In conclusion, healthcare providers should give the right level of importance to the management of ED in men with SCI, as this represents a major independent correlate of depression, which, in turn, might hinder physical rehabilitation and exacerbate physical health issues related to SCI.

Effects of Exercise-Based Interventions on Urogenital Outcomes in Persons with Spinal Cord Injury: A Systematic Review and Meta-Analysis

In this systematic review, objectives were to investigate dropout rates, adverse events, and effects of exercise-based therapies on urogenital function and quality of life (QoL) in persons with spinal cord injury (SCI). Database searches were conducted on MEDLINE, EMBASE, and CINAHL for studies examining any form of exercise intervention on urogenital function and/or QoL in adults with SCI. Quality of publications was evaluated using the Joanna Briggs Institute critical evaluation tools. When possible, Hedges' g was calculated for overall effect sizes. Subgroup analyses were conducted on sex and injury severity. Ten studies (228 participants) were included in this review. Three studies examined pelvic floor muscle training, and seven studies examined locomotor training. Overall quality of evidence was low because of small sample sizes and non-randomized designs in most studies. Dropout rates ranged from 12% to 25%, and adverse events were reported only in some studies investigating locomotor training. For lower urinary tract (LUT) outcomes, urodynamic findings were mixed despite moderately positive changes in maximum bladder capacity (g = 0.50) and bladder compliance (g = 0.37). Fairly consistent, but small, improvements were observed in LUT symptoms, primarily bladder awareness and incontinence. LUT QoL improved in most cases. Fewer data were available for sexual outcomes, and only minor improvements were reported. Subgroup analyses, based on sex and severity of injury, were inconclusive. There is some indication for the potential benefit of exercise on urogenital outcomes in persons with SCI, but there is insufficient evidence given the number of studies and heterogeneity of outcome measures.

Neurogenic Erectile Dysfunction. Where Do We Stand?

Erectile Dysfunction (ED) is the persistent inability to attain and maintain an erection sufficient to permit satisfactory sexual performance, causing tremendous effects on both patients and their partners. The pathophysiology of ED remains a labyrinth. The underlying mechanisms of ED may be vasculogenic, neurogenic, anatomical, hormonal, drug-induced and/or psychogenic. Neurogenic ED consists of a large cohort of ED, accounting for about 10% to 19% of all cases. Its diversity does not allow an in-depth clarification of all the underlying mechanisms nor a “one size fits all” therapeutical approach. In this review, we focus on neurogenic causes of ED, trying to elucidate the mechanisms that lie beneath it and how we manage these patients.

Altered sexual function after central neurological system trauma is reflective of region of injury; brain vs spinal cord

OBJECTIVE

To compare and contrast the contributory effects of traumatic brain injury (TBI) and spinal cord injury (SCI) on sexual function and social relationship opportunities, hypothesizing that patterns of change in sexual function would follow etiology.

DESIGN

Cross-sectional, case-matched survey of community living individuals with TBI, SCI or both (termed dual diagnosis).

PARTICIPANTS

Consecutive sample of participants with TBI (n = 25), SCI (n = 24) and dual diagnosis (n = 28), an average 3.6 years post-rehabilitation discharge.

METHODS

Participants were interviewed using a modified version of the 'Sexuality after Spinal Injury Questionnaire.'

RESULTS

Almost all respondents (97%) perceived adverse post-injury change in their experience of neurosexual function and/or social relationships. Physiological aspects of sexual function (e.g., erection, orgasm) were most affected by SCI whereas social relationships appeared more affected by TBI. People with dual diagnoses exhibited a combination of features. Participants with SCI (with or without TBI) were significantly more likely to have their concerns about sexual function discussed during rehabilitation than the TBI group.

CONCLUSION

TBI and SCI produce predictable impacts upon sexual function following injury, the impact of which were less frequently addressed during inpatient rehabilitation for those with TBI.

Effect of Different Forms of Activity-Based Recovery Training on Bladder, Bowel, and Sexual Function After Spinal Cord Injury

OBJECTIVES

To investigate whether the urogenital and bowel functional gains previously demonstrated post-locomotor step training after chronic spinal cord injury could have been derived due to weight-bearing alone or from exercise in general.

DESIGN

Prospective cohort study; pilot trial with small sample size.

SETTING

Urogenital and bowel scientific core facility at a rehabilitation institute and spinal cord injury research center in the United States.

PARTICIPANTS

Men and women (N=22) with spinal cord injury (American Spinal Injury Association Impairment Scale grades of A-D) participated in this study.

INTERVENTIONS

Approximately 80 daily 1-hour sessions of either stand training or nonweight-bearing arm crank ergometry. Comparisons were made with previously published locomotor training data (step; N=7).

MAIN OUTCOME MEASURES

Assessments at both pre- and post-training timepoints included cystometry for bladder function and International Data Set Questionnaires for bowel and sexual functions.

RESULTS

Cystometry measurements revealed a significant decrease in bladder pressure and limited improvement in compliance with nonweight-bearing exercise but not with standing. Although International Data Set questionnaires revealed profound bowel dysfunction and marked deficits in sexual function pretraining, no differences were identified poststand or after nonweight-bearing exercise.

CONCLUSIONS

These pilot trial results suggest that, although stand and weight-bearing alone do not benefit pelvic organ functions after spinal cord injury, exercise in general may contribute at least partially to the lowering of bladder pressure and the increase in compliance that was seen previously with locomotor training, potentially through metabolic, humoral, and/or cardiovascular mechanisms. Thus, to maximize activity-based recovery training benefits for functions related to storage and emptying, an appropriate level of sensory input to the spinal cord neural circuitries controlling bladder and bowel requires task-specific stepping.

Views and Experiences of Sex, Sexuality and Relationships Following Spinal Cord Injury: A Systematic Review and Narrative Synthesis of the Qualitative Literature

Research examining the effects of spinal cord injury on sexuality has largely focused on physiological functioning and quantification of dysfunction following injury. This paper reports a systematic review of qualitative research that focused on the views and experiences of people with spinal cord injury on sex and relationships. The review addressed the following research question: What are the views and experiences of people with spinal cord injury of sex, sexuality and relationships following injury? Five databases were relevant and employed in the review: CINAHL (1989–2016 only), PsychInfo, PubMed, Scopus and Web of Science, for research published between 1 January 1980 and 30 November 2019. After removing duplicates, 257 records remained and were screened using a two-stage approach to inclusion and quality appraisal. Following screening, 27 met the criteria for inclusion and are reported in the paper. The review includes studies from fifteen countries across five continents. Two main approaches to data analysis summary and thematic synthesis were undertaken to analyze the qualitative data reported in the papers. The analysis revealed four main themes: sexual identity; significant and generalized others, sexual embodiment; and; sexual rehabilitation and education.

Male genital sensation after spinal cord injury: a review

Genital sensation (GS) is an essential component of male sexual function. Genital sensory disturbance (GSD) caused by spinal cord injury (SCI) has a severe impact on the patients' sexual function but has garnered little research focus. Under normal conditions, GS encompasses the erection, ejaculation, sexual arousal, and orgasm courses associated with physiological and psychological responses in male sexual activity. However, in SCI patients, the deficiency of GS makes the tactile stimulation of the penis unable to cause sexual arousal, disturbs the normal processes of erection and ejaculation, and decreases sexual desire and satisfaction. To provide an overview of the contemporary conception and management of male GS after SCI, we review the innervation and sexual function of male GS in this article, discuss the effects of GSD following SCI, and summarize the current diagnosis and treatment of GSD in male SCI patients.

Supporting sexual adjustment from the perspective of men living with spinal cord injury

STUDY DESIGN

Descriptive phenomenological approach.

OBJECTIVES

This study explored the lived experience of sexuality for men after spinal cord injury (SCI) and described the current state of tools and resources available to assist with sexual adjustment from the perspective of men living with SCI.

SETTING

Men living in the community in Ontario, Canada.

METHODS

Six men (age 24-49 years) with complete or incomplete SCI (C4-T12; <1-29 years post injury) participated in one individual, in-depth, standardized, open-ended interview (68-101 min). Analysis was conducted using Giorgi's method, and involved within case analysis followed by cross-case analysis.

RESULTS

All participants reported that resources available to support sexual adjustment after SCI were inadequate, and the majority of men felt their healthcare providers lacked knowledge regarding, and comfort discussing sexuality after SCI. Men reported sexuality was not a priority of the rehabilitation centers and felt that healthcare providers did not understand the importance of addressing sexuality. Existing resources were described as too clinical and not necessarily relevant given changes in sensation and mobility post injury. Participants provided recommendations for the effective delivery of relevant sexual education information.

CONCLUSIONS

To improve quality of life for men after SCI, suitable resources must be available to support sexual rehabilitation post injury. Future research should focus on developing strategies to facilitate discussions about sexuality between individuals with SCI and healthcare providers, and on developing resources that are effective and relevant for these men.

Independent Association of Erectile Dysfunction and Low Testosterone Levels With Life Dissatisfaction in Men With Chronic Spinal Cord Injury

BACKGROUND

The loss of global functional independence, along with bladder, bowel, and sexual dysfunctions, may contribute to psychological distress and life dissatisfaction after spinal cord injury (SCI).

AIM

To explore the relationship of erectile function and androgenic status with life satisfaction, independently from confounders recognizable in spinal cord-injured men.

METHODS

100 consecutive men (49 ± 17 years) admitted to a rehabilitation program because of chronic SCI (≥1 year) underwent clinical/biochemical evaluations, including the assessment of life and sexual satisfaction using the Life-Satisfaction Questionnaire-9 (LiSat-9), erectile function using the International Index of Erectile Function-5 (IIEF-5), global and bowel-bladder functional independence using the Spinal Cord Independence Measure (SCIM) and measurement of total testosterone (TT) levels. The free testosterone level was calculated using the Vermeulen formula.

OUTCOMES

The outcomes include the relationship between sexual health and life satisfaction in men with SCI.

RESULTS

A LiSat-9 score <4, suggestive for life dissatisfaction, was exhibited by 49% of men. When compared with the life-satisfied group, a significantly higher percentage of them had sexual dissatisfaction and erectile dysfunction (ED); they also exhibited significantly lower levels of TT and calculated free testosterone (cFT) and a more severe impairment of bowel-bladder function. The life satisfaction degree correlated with sexual satisfaction degree, IIEF-5 score, TT, cFT, and bowel-bladder function degree. At the logistic regression model, including sexual LiSat-9 subscore and bowel-bladder SCIM subscore, only the former exhibited a significant negative association with life dissatisfaction. In a further logistic regression model, including the putative key determinants of sexual satisfaction, erectile function, and cFT levels, a higher odd of life dissatisfaction was independently associated both with a lower IIEF-5 score (OR: 0.93; 95% CI: 0.88, 0.98) and lower cFT levels (OR: 0.98; 95% CI: 0.98, 0.99).

CLINICAL IMPLICATIONS

In men with chronic SCI, assessment of erectile function and testosterone levels can help to predict life satisfaction.

STRENGTHS & LIMITATIONS

This is the first demonstration of the independent association of androgen deficiency and ED with life satisfaction in men with SCI. Prospective studies are warranted to clarify the cause-effect relationships.

CONCLUSIONS

In men with SCI, ED and low testosterone levels exhibit a significant independent association with life dissatisfaction; longitudinal intervention studies could explore possible effects of their treatment in improving sexual and life satisfaction in this population.

Severing the ventral funiculus in chronic spinal cord injury has the most deteriorating effect on spermatogenesis in rats

Sexual dysfunction, following spinal cord injury (SCI), is highly dependent on the extent of injury. SCI disrupts the supraspinal innervation of the reproductive organs; resulting in structural and functional deficits. Relating the extent of SCI to these changes could eventually improve diagnoses and treatment planning of sexual dysfunction following SCI. In the present study, following chronic SCI of different severities (1/3 dorsal SCI (1/3 SCI), 2/3 dorsal SCI (2/3 SCI), and complete transection (Tx)) at T8 spinal level, histological changes of seminiferous tubules parameters in testis were examined. The diameter of seminiferous tubules (DST) and epithelial height of seminiferous tubules (HST) were significantly decreased in all SCI groups compared to control and sham. In addition, DST in 2/3 SCI and Tx groups and HST in Tx group were significantly decreased in comparison with 1/3 SCI animals. Nonetheless, the diameter of seminiferous tubules' lumen decreased significantly in 2/3 SCI and Tx compared to control, sham, and 1/3 SCI groups. Concerning cellular component, the number of spermatocytes and spermatids layers significantly decreased in both 1/3 and 2/3 SCI in comparison to normal. However, Tx had the most prominent deteriorating effect on these layers; indicating impairment in the process of spermatogenesis. These results show that the spinal tracts are part of the neural circuitries innervating the testis and responsible for their structural support. These tracts are mainly distributed between the lateral and ventral funiculi at T8 spinal level. Consequently, sparing ventral funiculi in the SCI prevents the severe decline in spermatogenesis.

Priorities of desired functional recovery in Indian spinal cord injury patients

BACKGROUND

Spinal cord injuries (SCI) affect various functions and therefore the Quality of life (QOL) of these patients. Regaining even partial function can lead to improved QOL; making it crucial to know which functions are most important for these patients.

MATERIAL AND METHODS

This prompted us to conduct a survey in which subjects were asked to rank seven functions in order of importance to improve their quality of life. Survey was administered by personal interview of patients in different spinal injury rehabilitation centers across India.

RESULTS

A total of 112 patients completed the survey. Regaining arm and hand function was ranked as first priority by quadriplegics while bowel/bladder function and walking movements were ranked as 2nd and 3rd priority. Paraplegics ranked return of walking movements as their first priority, bladder/bowel recovery as second and trunk strength/sexual function as 3rd priority.

CONCLUSION

This knowledge empowers us to focus our research on what is most important for their QOL.

Traumatic and nontraumatic spinal cord injury: pathological insights from neuroimaging

Pathophysiological changes in the spinal cord white and grey matter resulting from injury can be observed with MRI techniques. These techniques provide sensitive markers of macrostructural and microstructural tissue integrity, which correlate with histological findings. Spinal cord MRI findings in traumatic spinal cord injury (tSCI) and nontraumatic spinal cord injury - the most common form of which is degenerative cervical myelopathy (DCM) - have provided important insights into the pathophysiological processes taking place not just at the focal injury site but also rostral and caudal to the spinal injury. Although tSCI and DCM have different aetiologies, they show similar degrees of spinal cord pathology remote from the injury site, suggesting the involvement of similar secondary degenerative mechanisms. Advanced quantitative MRI protocols that are sensitive to spinal cord pathology have the potential to improve diagnosis and, more importantly, predict outcomes in patients with tSCI or nontraumatic spinal cord injury. This Review describes the insights into tSCI and DCM that have been revealed by neuroimaging and outlines current activities and future directions for the field.

Conception and development of Sexual Health indicators to advance the quality of spinal cord injury rehabilitation: SCI-High Project

Context: Although spinal cord injury or disease (SCI/D) results in complex biological and psychosocial impairments that adversely impact an individual's overall quality of sexual life, sexual health is poorly integrated into the current rehabilitation processes. Therefore, it is vital to promote sexual health as a rehabilitation priority. Herein, we describe the selection of Sexual Health structure, process and outcome indicators for adults with SCI/D in the first 18 months after rehabilitation admission. Methods: Experts in sexual health and the SCI-High team identified key factors that influence the sexual health outcomes of rehabilitation interventions to inform Driver diagram development. This diagram informed the selection and development of indicators to promote a permissive environment for discussion of sexual health issues among regulated health care professionals (HCPs). A review of literature and psychometric properties of measurement tools facilitated final indicators selection. Results: The structure indicator is the proportion of rehabilitation HCPs who have completed annual preliminary sexual health training. The process indicator is the proportion of SCI/D inpatients that have a documented introduction to available local sexual health resources. The outcome indicator is a sexual health patient questionnaire used to assess sexual health patient outcomes and sexual health information/educational needs. Rapid-cycle piloting verified that the indicator tools developed are feasible for implementation. Conclusion: Successful implementation of the Sexual Health structure, process and outcome indicators will promote a permissive environment to enable open discussion, and lead to provision of equitable and optimal care related to sexual health following SCI/D. This will ultimately advance sexual health rehabilitation across the nation.

Telemetric monitoring of penile pressure during mating in rats after chronic spinal cord injury

In men with a spinal cord injury (SCI), erectile function, ejaculation, and fertility are severely impaired. The present study utilized a telemetric pressure transducer implanted into the corpus cavernosum of the penis to examine sexual function during awake mating behavior in a rat contusion model with a range of Infinite Horizon Impactor forces distributed between 150 and 215 kdyn. The mating behavior paradigm included examination of the counts, average pressure, and average duration for mounts, intromissions, and ejaculations. Male Wistar rats were mated with receptive females in 30-min sessions preinjury (sexual acclimation) and once per week for 6 wk beginning after a 2-wk recovery period post-SCI. All SCI animals had significant deficits in sexual function in the parameters measured. These deficiencies were more prevalent in a subset having less than 20% white matter sparing, likely a reflection of the extent of bilateral spino-bulbo-spinal sexual circuitry disruption at the lesion epicenter. The resulting discoordination of the autonomic and somatic reflex control of erection and ejaculation recorded using telemetry devices in an awake, behaving animal model provides an effective means of gauging sexual function deficits after SCI and could have utility for quantifying recovery after a therapeutic intervention.

Chronic Spinal Cord Injury Reduces Gastrin-Releasing Peptide in the Spinal Ejaculation Generator in Male Rats

Spinal cord injury (SCI) causes sexual dysfunction, including anejaculation in men. Likewise, chronic mid-thoracic contusion injury impairs ejaculatory reflexes in male rats. Ejaculation is controlled by a spinal ejaculation generator (SEG) comprised of a population of lumbar spinothalamic (LSt) neurons. LSt neurons co-express four neuropeptides, including gastrin-releasing peptide (GRP) and galanin and control ejaculation via release of these peptides in lumbar and sacral autonomic and motor nuclei. Here, we tested the hypothesis that contusion injury causes a disruption of the neuropeptides that are expressed in LSt cell bodies and axon terminals, thereby causing ejaculatory dysfunction. Male Sprague Dawley rats received contusion or sham surgery at spinal levels T6-7. Five to six weeks later, animals were perfused and spinal cords were immunoprocessed for galanin and GRP. Results showed that numbers of cells immunoreactive for galanin were not altered by SCI, suggesting that LSt cells are not ablated by SCI. In contrast, GRP immunoreactivity was decreased in LSt cells following SCI, evidenced by fewer GRP and galanin/GRP dual labeled cells. However, SCI did not affect efferent connections of LSt, cells as axon terminals containing galanin or GRP in contact with autonomic cells were not reduced following SCI. Finally, no changes in testosterone plasma levels or androgen receptor expression were noted after SCI. In conclusion, chronic contusion injury decreased immunoreactivity for GRP in LSt cell soma, but did not affect LSt neurons per se or LSt connections within the SEG. Since GRP is essential for triggering ejaculation, such loss may contribute to ejaculatory dysfunction following SCI.

Gray vs. White Matter Segmentation of the Conus Medullaris: Reliability and Variability in Healthy Volunteers

BACKGROUND AND PURPOSE

Magnetic resonance imaging (MRI)-derived spinal cord (SC) gray and white matter (GM/WM) volume are useful indirect measures of atrophy and neurodegeneration over time, typically obtained in the upper SC. Neuropathological evidence suggests that in certain neurological conditions, early degeneration may occur as low as the sacral SC. In this study, the feasibility of GM/WM segmentation of the conus medullaris (CM) was assessed in vivo.

METHODS

Twenty-three healthy volunteers (11 female, mean age 47 years) underwent high-resolution 3T MRI of the CM using a 3-dimensional fast field echo sequence. Reproducibility of the volume measurements was assessed in 5 subjects (2 female, 25-37 years) by one rater who repeated the analysis 3 times and also with 2 additional raters working independently in order to calculate the intra- and interrater coefficient of variation (COV), respectively. Furthermore, the influence of age, gender, spine and SC metrics on tissue-specific measures of the CM was investigated.

RESULTS

Volumetric CM analyses (N = 23) for the SC, GM, and WM revealed a mean (SD) total volume of CM-TV = 1746.9 (296.7) mm³ , CM-GM-TV = 731.2 (106.0) mm³ , and CM-WM-TV = 1014.6 (211.3) mm³ , respectively. The intra-rater COV for measuring the CM-TV and CM-GM-TV was 3.38% and 7.42%, respectively; the interrater COV was 3.43% and 10.80%, respectively. Using age, gender, spine and SC metrics in regression models substantially reduced group variability for CM-TV, CM-WM-TV, and CM-GM-TV by up to 39.2%, 42.7%, and 21.2%, respectively.

CONCLUSIONS

The results from this study demonstrate the feasibility of obtaining tissue-specific volume measurements in the CM by means of MRI with good reproducibility and provide normative data for future applications in neurological diseases affecting the lower SC.

[Spanish validation of the Autonomic Standards Assessment Form in spinal cord injuries]

INTRODUCTION AND OBJECTIVES

Autonomic nervous system (ANS) dysfunction in patients with spinal cord injury (SCI) severely impacts morbidity and mortality. However, research initiatives aiming to gain insight into the direct impact of ANS dysfunction on health outcomes in persons with SCI are still lacking. Thus, this study had 2main objectives: 1) to translate into Spanish the revised edition of the International Standards on documentation of remaining Autonomic Function after SCI (ISAFSCI), and 2) to describe the impact of ANS dysfunction in a sample of SCI patients.

MATERIAL AND METHODS

Cross-sectional observational pilot study in 51 traumatic SCI patients (> 1 year after injury). Demographic, medical and ISAFSCI data were studied.

RESULTS

The Spanish version of the ISAFSCI showed that the most altered systems in the sample were sweating control (above-lesion hyperhidrosis in 33.3%; below-lesion hyperhidrosis in 17.6%; below-lesion hypohidrosis in 21.6%) and temperature control (hyperthermia in 76.5%). In addition, 74.5% of the sample had complete loss of control of the lower urinary tract, and 82.4% had no control of the bowel. Finally, genital arousal was reflex in 47.1% and orgasm and ejaculation were reduced or altered in most of the patients (92.2% and 84.3%, respectively).

CONCLUSION

The Spanish version of the ISAFSCI is a useful and practical tool, and can be employed in clinical practice to assess ANS function in patients with SCI. Understanding the role of ANS in persons with SCI is crucial to improve their health status and reduce secondary complications post-SCI, and consequently help to improve the clinical management in these individuals.

A Multidisciplinary Approach to Sexual and Fertility Rehabilitation: The Sexual Rehabilitation Framework

Many studies have identified improvement in sexual function as a priority for persons with spinal cord injury (SCI). Due to the various secondary sensory, motor, and autonomic consequences following SCI and due to the complexity of sexuality per se, this area can be overwhelming to many health care professionals. The literature indicate that sexual and fertility rehabilitation must be addressed in a biopsychosocial manner and include various disciplines. The multidisciplinary utilization of a Sexual Rehabilitation Framework (SRF) allows the medical and/or psychosocial factors that impede or improve sexual and reproductive function to be examined. The SRF is a user-friendly and simplified way to proactively address the major biopsychosocial areas of sexuality and to create a plan of action for the person with SCI. It is an adjunct tool to the full sexual history, and it encourages all disciplines involved in SCI rehabilitation to address the issue of sexual function in the same manner as they would other activities of daily living. Eight areas are included in the SRF: sexual drive/interest, sexual functioning, fertility and contraception, factors associated with the condition, motor and sensory influences, bladder and bowel influences, sexual self-view and self-esteem, and partnership issues. The use of the SRF is encouraged in both inpatient and outpatient settings. Multidisciplinary or interdisciplinary team work is encouraged in sexual and fertility rehabilitation to move clinicians toward providing proactive and comprehensive care for individuals with SCI or other chronic disabilities.

Neural Control and Physiology of Sexual Function: Effect of Spinal Cord Injury

Objective: To present the current understanding of normal anatomy, physiology, sexual physiology, pathophysiology and the consequential sexual changes and dysfunctions following a spinal cord injury (SCI). Methods: Narrative review of the latest literature. Results: Peripheral innervations of the pelvis involve 3 sets of efferent neurons coordinated though the pelvic plexus (somatic, thoracolumbar sympathetic, and sacral parasympathetic), and these are under cerebral descending excitatory and inhibitory control. SCI, depending on the level of lesion and completeness, can alter this cerebral control, affecting the psychological and reflexogenic potential for genital arousal and also ejaculation and orgasm. During arousal, nitric oxide is the main neurotransmitter for smooth muscle relaxation in both male and female erectile tissue. In men, erection, ejaculation, and orgasm are under separate neurological control and can be individually affected by SCI. Conclusions: Since sexual function is rated amongst the highest priorities by individuals living with SCI, methods employed to affect the neurological changes to maximize sexual neurophysiology prior to initiating medical therapies including paying attention to sexual sensate areas and visceral signals with mindfulness techniques, practicing body mapping, and sexual stimulation of sensate areas to encourage neuroplasticity. Attention should be paid to the biopsychosocial sexual contexts within which persons with SCI live to maximize their sexual and fertility rehabilitation.

The impact of different scenarios for intermittent bladder catheterization on health state utilities: results from an internet-based time trade-off survey

AIMS

Intermittent catheterization (IC) is the gold standard for bladder management in patients with chronic urinary retention. Despite its medical benefits, IC users experience a negative impact on their quality of life (QoL). For health economics based decision making, this impact is normally measured using generic QoL measures (such as EQ-5D) that estimate a single utility score which can be used to calculate quality-adjusted life years (QALYs). But these generic measures may not be sensitive to all relevant aspects of QoL affected by intermittent catheters. This study used alternative methods to estimate the health state utilities associated with different scenarios: using a multiple-use catheter, one-time-use catheter, pre-lubricated one-time-use catheter and pre-lubricated one-time-use catheter with one less urinary tract infection (UTI) per year.

METHODS

Health state utilities were elicited through an internet-based time trade-off (TTO) survey in adult volunteers representing the general population in Canada and the UK. Health states were developed to represent the catheters based on the following four attributes: steps and time needed for IC process, pain and the frequency of UTIs.

RESULTS

The survey was completed by 956 respondents. One-time-use catheters, pre-lubricated one-time-use catheters and ready-to-use catheters were preferred to multiple-use catheters. The utility gains were associated with the following features: one time use (Canada: +0.013, UK: +0.021), ready to use (all: +0.017) and one less UTI/year (all: +0.011).

LIMITATIONS

Internet-based survey responders may have valued health states differently from the rest of the population: this might be a source of bias.

CONCLUSION

Steps and time needed for the IC process, pain related to IC and the frequency of UTIs have a significant impact on IC related utilities. These values could be incorporated into a cost utility analysis.

Women's experiences of sexuality after spinal cord injury: a UK perspective

STUDY DESIGN

Cross-sectional phenomenological qualitative study.

OBJECTIVES

To investigate women's experience of sexuality after spinal cord injury (SCI) with a focus on rehabilitation and manging practical impact.

SETTING

Women with SCI living in the community in United Kingdom (UK).

METHODS

Participants were recruited via three UK SCI centres, ensuring tetraplegia, paraplegia and cauda equina syndrome representation. Single semi-structured interviews exploring individual's experiences around sexuality following SCI were recorded and transcribed for thematic analysis.

RESULTS

Twenty-seven women aged 21-72 years, sexually active since SCI were interviewed, each lasting 17-143 min (mean 55 min). Six key themes emerged: physical change, psychological impact, dependency, relationships and partners, post injury sexual life and sexuality rehabilitation.

CONCLUSIONS

Sexuality remains an important, valued aspect of female identity following SCI; sexual activity continues and though altered remains enjoyable and rewarding. Sexuality rehabilitation should commence early, preparing women for altered sexual sensation, disclosure of altered sexual function to partners, and encouraging early self-exploration. Techniques optimising continence management in preparation for and during sex should be taught. Participants identified a need for women-only education and support groups, increased peer support, self-esteem, communication and social skills training and even fashion advice and pampering sessions during rehabilitation. Support and education for partners are needed. Staff require support to be knowledgeable and confident in addressing women's sexuality needs. Use of the Ex-PLISSIT model for psychosexual support could help staff to better meet these needs.

User Evaluation of the Neurodildo: A Mind-Controlled Sex Toy for People with Disabilities and an Exploration of Its Applications to Sex Robots

In this paper, we present the Neurodildo, a sex toy remotely controlled by brain waves, which is pressure sensitive and has electrical stimulation (e-stim) feedback. The Neurodildo was originally presented as a conference paper at the 3rd International Congress on Love and Sex with Robots (2017). We designed and explored the application of a mind-controlled sex toy for the people with mobility disabilities, for example with spinal cord injury (SCI), who have difficulty handling a commercial toy and that might experience difficulties in a sexual encounter. The system consists of the sex toy with Bluetooth and sensors, the brain-computer interface (BCI) headset, the e-stim device, and a computer for running the necessary software. The first user wears the headset and the e-stim device, and by focusing in trained patterns, he/she can control the vibration of the sex toy. The pressure applied to the sex toy by the second user is measured by sensors and transmitted and converted to the first user, who feels muscle contractions. We discuss the design process, the limitations of the prototype and how evaluating the user requirements is necessary for a better product. We also included a background and discussion on the application of sex robots for assisting disabled people and how the Neurodildo could be integrated with this futuristic technology. The goal of this project is to design a sex toy that might help people with disabilities and people in long-distance relationships (LDR), trying to fill the gap of sex toys designed for people with disabilities.

Sexual Health in Men With Traumatic Spinal Cord Injuries: A Review and Recommendations for Primary Health-Care Providers

Sexual health has been well established as a salient priority for men following traumatic spinal cord injury; yet, it continues to be under-addressed by health-care providers in both inpatient and community settings. Given that most men with traumatic spinal cord injuries will be followed by community-based primary health-care providers, including family physicians and nurse practitioners, for their long-term health-care needs, these clinicians are well positioned to address ongoing sexual health issues with this population. A scoping review of literature published between 2007 and 2017 inclusive was undertaken to identify what is known about the sexual health of men with spinal cord injuries. Twenty articles met the inclusion criteria. The findings are presented in four themes: (a) patterns and diversity of sexual health concerns; (b) sexual health recovery as an ongoing priority; (c) clinical barriers to addressing sexual health concerns, and (d) recommended interventions and strategies for primary health-care providers. The findings indicate that physiological changes as well as psychological and social factors influence men’s sexual function following spinal cord injury, and that sexual health recovery is an enduring rehabilitation priority. Several barriers including lack of sexual rehabilitation services and consensus around clinician roles, and societal stigmas related to disability and sexuality impede treatment. Attention to sexual health recovery has mainly focused on formal rehabilitation settings; however, many evidence-based clinical strategies and resources are relevant to and adaptable for primary care providers caring for these men in the community.

Positive sexuality in men with spinal cord injury

STUDY DESIGN

Prospective study.

OBJECTIVES

To analyze determinants of sexual pleasure in men with spinal cord injury (SCI).

SETTING

Centre Bouffard-Vercelli, Cerbere, France.

METHODS

Face to face interviews with men with chronic SCI who had an active sex life with a female partner, reliable erections permitting intercourse, and sought regular counselling with a sex therapist. Questionnaires: the International Index of Erectile Function (IIEF) and a modified Sexual History Form.

RESULTS

Thirty-three men were enroled. IIEF subscores were high for erectile function (mean 27.6/30), sexual desire (mean 8.8/10), intercourse satisfaction (mean 11.9/15) and overall satisfaction (mean 8.7/10). Overall satisfaction was significantly related to the level (p < 0.01) but not the severity of the lesion (p = 0.59), positively correlated with intercourse satisfaction (p < 0.001), negatively with age (p < 0.05) and age at injury (p < 0.01), but not with time since injury (p = 0.80). Orgasm was reported by 14 men (42%), and correlated strongly with antegrade ejaculation (p < 0.001), but not with overall satisfaction (p = 0.81). All men, except one, described enjoyable, long foreplay. Intercourse was associated with sensations of pleasure for 30 men (90%). After intercourse, 26 men (78%) experienced sensations of fulfilment, and 30 (90%) of relaxation. Most men expressed frustration, primarily in the case of absent or intermittent ejaculation or orgasm. Men described their female partners as taking more initiatives, and having a satisfactory sex life.

CONCLUSIONS

A positive and satisfying sex life is achievable by the men's willingness to adapt their sexual behaviour coupled with the reward of physical pleasure experienced during intercourse.
