Treatment of chronic pain in children and adolescents

System Architecture for VR Yoga Therapy Platform with 6-DoF Whole-Body Avatar Tracking

Chronic pain is a leading cause of morbidity among children and adolescents affecting 35% of the global population. Pediatric chronic pain management requires integrative health methods spanning physical and psychological subsystems through various mind-body interventions. Yoga therapy is one such method, known for its ability to improve the quality of life both physically and psychologically in chronic pain conditions. However, maintaining the clinical outcomes of personalized yoga therapy sessions at-home is challenging due to fear of movement, lack of motivation, and boredom. Virtual Reality (VR) has the potential to bridge the gap between the clinic and home by motivating engagement and mitigating pain-related anxiety or fear of movement. We developed a multi-modal algorithmic architecture for fusing real-time 3D human body pose estimation models with custom developed inverse kinematics models of physical movement to render biomechanically informed 6-DoF whole-body avatars capable of embodying an individual's real-time yoga poses within the VR environment. Experiments conducted among control participants demonstrated superior movement tracking accuracy over existing commercial off-the-shelf avatar tracking solutions, leading to successful embodiment and engagement. These findings demonstrate the feasibility of rendering virtual avatar movements that embody complex physical poses such as those encountered in yoga therapy. The impact of this work moves the field one step closer to an interactive system to facilitate at-home individual or group yoga therapy for children with chronic pain conditions.

Animal-Assisted Psychotherapy for Pediatric Chronic Pain: Case Series of an Open Pilot Study to Test Initial Feasibility and Potential Efficacy

Objective

Chronic pain is a common complaint in children and adolescents, placing an enormous burden on individuals, their families, and the healthcare system. New innovative approaches for the treatment of pediatric chronic pain (PCP) are clearly warranted, as drop-out rates in intervention studies are high and it can be difficult to engage patients with PCP in therapy. Here, animal-assisted interventions (AAIs) might be promising, since there is preliminary evidence for the approach in adults with chronic pain, and AAIs are generally known to foster the therapeutic motivation of patients. To date, however, AAIs have not been examined in pediatric chronic pain.

Methods

The aim of this open pilot study was to examine the initial feasibility of recruitment and potential efficacy of an animal-assisted group psychotherapy (including horses, rabbits, chickens, goats, and a dog), providing case reports of three children with chronic pain. We applied a mixed-methods approach, including the conductance of semi-structured interviews and assessment of quantitative pre-post data with a focus on pain severity, avoidance behavior, pain acceptance, and ability to defocus from the pain.

Results

The three participating girls (age: 9-12 years) reported chronic pain in the head and abdomen. The process of recruitment turned out to be challenging. All three children reported reduced pain-related disability and pain-related distress, as well as an increased ability to accept pain and to defocus from the pain. The qualitative data revealed that patients and their parents had a positive attitude towards AAIs.

Conclusion

Our initial open pilot study is the first to investigate AAIs in the context of pediatric chronic pain. Notably, we had difficulties in the recruitment procedure, mostly due to the Covid-19 situation. Based on three case reports, we found some first indication that AAI approaches might be associated with symptom changes. Future randomized-control studies with larger sample sizes are clearly warranted.

[Chronic pain in pediatric primary care : What do adolescents and parents expect and how do they perceive treatment?]

BACKGROUND AND OBJECTIVES

Recurrent pain in childhood and adolescence is a common health problem. Pediatricians are usually the patients' first contact person. The current study investigated patients' and parents' expectations when consulting a pediatrician and their rating of the treatment.

MATERIALS AND METHODS

In 36 pediatric practices, 224 patients with recurrent pain and 273 parents participated in this cross-sectional tablet survey. The collected data included the motivation for arranging a physician consultation, pain concept, treatment expectations, and assessment of treatment. Additionally, the patients' age was investigated as an influencing factor.

RESULTS

The patients' and parents' predominant motivation for arranging a consultation was the clarification of the cause of pain. Older patients were additionally motivated by frequent but ineffective drug use. Predominantly in older patients, a biopsychosocial pain explanation was identified. Approximately half of all patients and parents indicated biological and psychological influencing factors. The most frequent expectation of the consultation was obtaining information on pain management. Overall, consultations were rated very positively, especially when patients and parents felt understood and taken seriously.

CONCLUSIONS

Information about the cause of pain and pain management are essential for patients and parents. Besides good communication, sufficient time resources of the practitioner are required.

The Mediating Effect of Self-Control on Depression and Tendencies of Eating Disorders in Adolescents

Self-control is very important for the adaptation among adolescents. It is associated with depression and tendencies of eating disorders. This study aimed to investigate the relationship between the two and the mediating role of self-control for adolescents. In total, 1,231 adolescents (11-18 years) participated in this study. Self-control, depression, and tendencies of eating disorders were evaluated using the Dual-Mode of Self-Control Scale (DMSC-S), 11-item Kutcher Adolescent Depression Scale (KADS-11), and Eating Attitudes Test (EAT-26). The correlations among these factors were analyzed using mediating effect models. Girls had higher scores on the both subscales (impulse system and control system) of DMSC-S (P < 0.001). Those between 15-18 years had higher scores on impulse system than those between 11-14 years (P < 0.001). A significant mediating effect (12.8%) of the impulse system was observed between depression and tendencies of eating disorders in adolescents.

[Medical pain care for children and adolescents with chronic pain in Germany : An inventory]

Chronic pain in children and adolescents is increasing in prevalence, affects the quality of life, predisposes to pain in adulthood and causes numerous contacts to the healthcare system. In contrast, the number of therapeutic offers tailored to the special needs of this age group is insufficient and confusing. The working group on pain in children and adolescents of the German Pain Society therefore documented appropriate facilities in a questionnaire survey carried out using a snowball system. The response rate of 27/109 questionnaires was low. Thus, the results may not be entirely representative. Nevertheless, the heterogeneity of the offers and in total an undersupply became very clear. In order to improve the care situation, joint efforts by the various pediatric subdisciplines dealing with pain, an increase in the number of child pain treatment centers and a better networking are necessary.

Physical Therapy Outcome Measures for Assessment of Lower Extremity Chronic Pain-Related Function in Pediatrics

PURPOSE

To assess the clinical utility of 5 physical therapy (PT) outcome measures in quantifying functional changes in pediatric lower extremity chronic pain treated at a hospital-based interdisciplinary rehabilitation center.

DESIGN

This was a cross-sectional study with retrospective review of 173 individuals, 8 to 18 years old, treated from June 2008 to 2013.

METHODS

The measures used were the Timed Up and Go, Timed Up and Down Stairs, Bruininks-Oseretsky Test of Motor Proficiency, Second Edition, 6-minute walk test, and Lower Extremity Functional Scale. Participant performance was correlated with demographic characteristics, the Functional Disability Index, Multidimensional Anxiety Scale for Children, Child Depression Inventory, and Canadian Occupational Performance Measure.

RESULTS

Scores from all 5 PT measures showed significant improvement following treatment. Functional Disability Index correlated to every PT measure except the 6-minute walk test.

CONCLUSIONS

This study supports the clinical use of these PT measures to track functional progress after rehabilitative treatment of lower extremity chronic pain-related disability.

Prevalence of TMD and level of chronic pain in a group of Brazilian adolescents

AIMS

To determine the prevalence of temporomandibular disorders and associated factors in an adolescent sample from Recife, Brazil.

MATERIALS AND METHODS

A cross-sectional study was conducted with 1342 adolescents aged 10-17 years. The Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) was used by calibrated examiners to evaluate the presence and levels of chronic pain. To evaluate the socioeconomic conditions, the subjects answered the Brazilian Economic Classification Criteria (CCEB) questionnaire. Data were analyzed by means of binary logistic regression in SPSS.

RESULTS

The results showed that 33.2% of the subjects had TMD irrespective of age (p = 0.153) or economic class (p = 0.653). Statistically significant associations were found between TMD and female gender (p = 0.017), headache/migraine in the past six months (p<0.001), chronic pain (p<0.001) and chronic pain level (p<0.001). In the final model, logistic regression showed that the level of chronic pain and the headache/migraine in the past six months were related to the presence of TMD.

CONCLUSIONS

The prevalence of TMD was considered high (33.2%) and adolescents with chronic pain and headache in the past six months were more likely to have TMD.

CLINICAL RELEVANCE

The data contribute to the understanding of TMD among adolescents and to the development of preventive measures and polices to identify the dysfunction promptly.

Prevalence of autism traits and attention-deficit hyperactivity disorder symptoms in a clinical sample of children and adolescents with chronic pain

Purpose

Recent research has suggested that autism spectrum disorder (ASD) and attention-deficit hyperactivity disorder (ADHD) may be comorbid to pediatric chronic pain, but the empirical support is yet scarce. Therefore, the current study aimed to investigate the occurrence of traits and symptoms consistent with clinically significant ASD and ADHD in a group of children and adolescents with chronic debilitating pain and examine potential differences in pain and demographic variables between children with and without clinically significant traits and symptoms of ASD and ADHD.

Patients and methods

This cross-sectional study included 146 parent–child dyads (102 girls, 111 mothers, children 8–17 years) consecutively referred to a tertiary pain clinic. Parents completed the Social Responsiveness Scale to assess autistic traits, and Conners-3 to measure symptoms of ADHD in their children. Children completed the Lübeck Pain Questionnaire to evaluate experienced pain.

Results

Among children, 20 (13.7%) received scores consistent with clinically significant ASD and 29 (19.9%) received scores consistent with clinically significant ADHD, with a combined prevalence of clinically significant ASD/ADHD traits and symptoms of 26% of the total sample. Only 4.8% of children were previously diagnosed with either disorder. Among children with clinically significant ASD traits, girls were more prevalent, parents reported lower health, and the pain was more likely triggered by being in school. Among children with clinically significant ADHD symptoms, there were no gender differences and pain was more likely triggered by the family situation and new situations. No differences regarding pain intensity, duration, or frequency were found between children with and without clinically significant ASD traits or ADHD symptoms.

Conclusion

Children with debilitating chronic pain, particularly girls, may present with an elevated risk of having a comorbid, possibly high-functioning, neurodevelopmental disorder. Results suggest that clinical assessment of pediatric chronic pain should include screening for neurodevelopmental disorders.

Physical and occupational therapy outcomes: Adolescents' change in functional abilities using objective measures and self-report

PURPOSE

This study evaluates the clinical usefulness of patient-rated and objective measures to identify physically-oriented functional changes after an intensive chronic pain program in a pediatric setting. Past studies have demonstrated the importance of adolescents' perception of their abilities and measurement tools used for rehabilitation outcomes within physical and occupational therapy; however, these tools used are not often easily utilized or have not been examined with a pediatric chronic pain population. In chronic pain rehabilitation, it is important to have a primary focus on functional improvement not on pain reduction as a leading outcome. This study examines how both self-report and objective physical activity measures can be meaningful constructs and can be used as reliable outcome measures. It was hypothesized that adolescents completing an interdisciplinary pain rehabilitation program would report functional gains from admission to discharge, and that perceived gains in physical ability would be associated with objective physical activities. Further, it was hypothesized that gains in functioning would be associated with mild pain reduction.

METHODS

Data from 78 children and adolescents with chronic pain that participated in an intensive multidisciplinary treatment program completed self-report measures including the Lower Extremity Functional Scale (LEFS), Upper Extremity Functional Index (UEFI). In addition, adolescents were objectively monitored for repetitions of selected physical activities for 1min intervals.

RESULTS

Data demonstrated significant gains in all measures of functioning during the program. Correlations between self-report and objective outcomes suggest they are measuring similar yet distinct factors.

CONCLUSIONS

The LEFS, UEFI, and objective exercises provide a meaningful way to track progress in pediatric chronic pain rehabilitation. Despite similarities, they appear to track separate but related aspects of rehabilitation and capture important short-term response to rehabilitation. Both measures appear distinct from pain as an outcome. These findings increase our understanding of rehabilitation practices provide opportunities to promote clinical improvement in pediatric pain.

IMPLICATIONS

The use of self-report measures along with objective measures can help therapists gain understanding in regards to a patient's insight and how that may impact their overall outcome compared to the use of a single outcome measure. Viewing these rated measures at any point in the rehabilitation process can be useful to facilitate discussion about challenges they can identify and how therapies can facilitate improvement and functional gains.

Chronic Pain in Children: A Look at the Referral Process to a Pediatric Pain Clinic

We reviewed the referral pattern of children with chronic pain to a specialized pediatric pain clinic. Data were obtained from referring physicians and medical records and during an interview with patients and their parents by physicians and a psychologist. We analyzed the following: referral diagnosis, demographics, duration of symptoms, number of physicians previously consulted, school attendance, sports activities, presence of psychological disorders, final team diagnosis, and outcomes. Children had been experiencing pain for 34 ± 55 months. Patients had consulted on average 3 physicians in addition to their pediatrician. 32% of the patients had missed at least 10 days of school in a calendar year, and 47% had stopped playing sports. 15% had an operation because of pain that had been unsuccessful. The most common missed diagnosis was anxiety (25%) and depression (13%). 69% of the patients were back to school and/or playing sports within 4 months from our initial consultation. 32% of the patients did not make any progress during the follow-up period. The most common reasons for failure to improve were no compliance with the recommended treatments and poorly controlled major mood disorder. The time to refer children with chronic pain for specialized care could be extremely long causing significant social and psychological consequence.

Evidence-Based Psychological Interventions for the Management of Pediatric Chronic Pain: New Directions in Research and Clinical Practice

Over the past 20 years our knowledge about evidence-based psychological interventions for pediatric chronic pain has dramatically increased. Overall, the evidence in support of psychological interventions for pediatric chronic pain is strong, demonstrating positive psychological and behavioral effects for a variety of children with a range of pain conditions. However, wide scale access to effective psychologically-based pain management treatments remains a challenge for many children who suffer with pain. Increasing access to care and reducing persistent biomedical biases that inhibit attainment of psychological services are a central focus of current pain treatment interventions. Additionally, as the number of evidence-based treatments increase, tailoring treatments to a child or family’s particular needs is increasingly possible. This article will (1) discuss the theoretical frameworks as well as the specific psychological skills and strategies that currently hold promise as effective agents of change; (2) review and summarize trends in the development of well-researched outpatient interventions over the past ten years; and (3) discuss future directions for intervention research on pediatric chronic pain.

Validation and clinical application of a biopsychosocial model of pain intensity and functional disability in patients with a pediatric chronic pain condition referred to a subspecialty clinic

Background. Pediatric chronic pain is considered to be a multidimensional construct that includes biological, psychological, and social components. Methods. The 99 enrolled study patients (mean age 13.2 years, 71% female, 81% Caucasian) and an accompanying parent completed a series of health-related questionnaires at the time of their initial appointment in a pediatric chronic pain medicine clinic. Results. Significant correlations (r ≥ 0.30, P < 0.05) were observed between pediatric chronic pain intensity and patient anxiety, patient depression, patient pain coping, parent chronic pain intensity, and parent functional disability. Pediatric chronic pain intensity was significantly associated with patient anxiety (P = 0.002). Significant correlations (r ≥ 0.30, P < 0.05) were observed between pediatric functional disability and patient chronic pain intensity, patient anxiety, patient depression, patient pain coping, parent chronic pain intensity, parent functional disability, parent anxiety, parent depression, and parent stress. Pediatric functional disability was significantly associated with patient chronic pain intensity (P = 0.025), patient anxiety (P = 0.021), patient pain coping (P = 0.009), and parent functional disability (P = 0.027). Conclusions. These findings provide empirical support of a multidimensional Biobehavioral Model of Pediatric Pain. However, the practical clinical application of the present findings and much of the similar previously published data may be tenuous.
