Musculoskeletal Pain in Children and Adolescents: A Way Forward

Adolescent and Parent Experiences and Perceived Effectiveness of Physical Interventions for Chronic Musculoskeletal Pain: A Qualitative Study

INTRODUCTION

There is a paucity of evidence on the effectiveness of physical interventions for chronic musculoskeletal pain affecting adolescents. This study explored adolescent and parent experiences and perceived effectiveness of physical intervention for chronic musculoskeletal pain in the UK.

METHODS

Using semi-structured interviews, 21 young people receiving treatment for chronic musculoskeletal pain and 21 parents were interviewed regarding their healthcare experiences. Data regarding experiences of physical interventions were analysed in this secondary qualitative analysis using inductive reflexive thematic analysis.

RESULTS

Three themes that captured why adolescents and parents perceived physical interventions to be effective or not were (1) feeling in control, (2) the right person and an explanation that makes sense and (3) make a difference to me not my foot.

DISCUSSION

Core concepts that appeared to influence the perceived effectiveness of physical interventions from the perspectives of adolescents and parents included facilitating adolescent autonomy, establishing a therapeutic alliance on the basis of trust and focusing physiotherapy treatment on meaningful participation in life.

CONCLUSION

There were no ideal physical interventions. The themes convey the importance of therapeutic alliance, intervention context and the need for personalised care.

Developing and assessing the measurement properties of an instrument to assess the impact of musculoskeletal pain in children aged 9 to 12-the pediatric musculoskeletal pain impact summary score

BACKGROUND

Despite the high prevalence of musculoskeletal (MSK) pain in children, there is a lack of instruments to measure the impact of MSK pain on children's activity and participation.

OBJECTIVE

To assess the reliability and construct validity of the Pediatric MSK Pain Impact summary score in school children (aged 9 to 12) with MSK pain.

METHODS

We used a pragmatic approach in a reflective framework to assess internal consistency, structural validity, convergent validity, and discriminative validity in a sample of 615 children with MSK pain.

RESULTS

The confirmatory factor analysis results indicate that the summary score has limited internal consistency and construct validity. The estimated Cronbach's alpha was 0.63, and most goodness of fit indices met the recommended thresholds (SRMR = 0.030; GFI = 0.993, CFI = 0.955, RMSEA 0.073), although they were close to the lower bounds of the thresholds. The convergent validity showed appropriate correlation of the summary score with quality of life (r = -0.33), care-seeking (r = 0.45), and medication intake (r = 0.37). Discriminative validity showed that the instrument can discriminate between the impact of pain on children with frequent and infrequent (2.93; 95% CI: 2.36 - 3.50) MSK pain.

CONCLUSION

The Pediatric MSK Pain Impact summary showed limited internal consistency and construct validity; however, it can discriminate between children with frequent and infrequent pain. The results are promising for clinical and research practices as it is a short and convenient tool to be used in school-aged children.

Relationship between low-back pain and flexibility in children: A cross-sectional study

Low-back pain is common among school-aged children. Decreased trunk flexibility in childhood influences low-back pain in adulthood. Previous studies examining the association between low-back pain and trunk flexibility in children are insufficient. Examining this association among elementary school children may help to better understand trunk flexibility in children with low-back pain and to modify the management of inflexibility. Therefore, this study aimed to identify the prevalence of low-back pain and its relationship with physical function among elementary school students. School-aged children aged 6-12 years were recruited in Japan between May 2018 and March 2023. Fingertip-to-floor distance, back muscle strength, pelvic tilt angle during gait, and the visual analog scale for low-back pain were measured. In addition, factors independently related to low-back pain were determined through logistic regression analysis. Low-back pain was reported in 9.6% of the 394 participants (boys, 191; girls, 203). All children with low-back pain presented with back pain when they moved; however, the pain was non-specific. Logistic regression analysis showed that the fingertip-to-floor distance was an independent risk factor for low-back pain (odds ratio, 0.921; p = 0.007). The odds ratios calculated in the logistic regression analysis confirmed that low-back pain frequency increased as the fingertip-to-floor distance decreased. The risk of low-back pain was associated with inflexibility, regardless of sex and muscle strength. These findings suggest that children with low-back pain must increase their trunk and lower extremity flexibility.

Musculoskeletal complaints and associated factors in school children aged between 6 and 13 years in Istanbul during the COVID-19 pandemic: A cross-sectional study

BACKGROUND: Following the first COVID-19 cases in Turkey, face-to-face education was ceased after March 16, 2020 until the end of the educational year (i.e. June 19, 2020) and education was substituted remotely due to confinement. OBJECTIVE: This study aims to investigate the frequency of musculoskeletal complaints in school-age children and associated risk factors including reduced physical activity, increased screen time and poor ergonomics conditions in school-age children during the pandemic. METHODS: This cross-sectional study included parents or guardians of 960 students aged between 6–13 years old with a non-randomized sampling. A survey was administered consisting of 66 items related with sociodemographic characteristics of the children and family, online education hours, technological device(s) used, screen time, type of physical activity, presence of musculoskeletal problems and poor ergonomics conditions such as incorrect sitting posture. RESULTS: Logistic regression results demonstrated that age, excess weight gain, total daily screen time, smartphone use, incorrect sitting posture were associated with musculoskeletal complaints. CONCLUSION: The long-term closure of schools due to the pandemic may have led to an increase in musculoskeletal complaints in 6–13 years old children, based on the factors identified in this study, which were excess weight gain, increased screen time and incorrect sitting posture. These findings might help education and health authorities to develop strategies to improve musculoskeletal health of children especially in emergencies such as the pandemic.

What Works When Treating Children and Adolescents With Low Back Pain?

BACKGROUND

Low back pain is a common health condition for all ages. One quarter to a third of children report persistent pain, including low back pain.

CLINICAL QUESTION

The aim of this Clinical Commentary is to provide an overview of evidence-based treatment approaches for children and adolescents with low back pain.

KEY RESULTS

Physical, psychological, and pharmacological interventions are effective in reducing pain intensity and disability. Interdisciplinary and patient- and family-centered treatment approaches are the gold standard for persistent pain in children and adolescents. Communication between health professionals, children, and parents is a key part of a therapeutic alliance. The use of holistic and complementary therapies is not supported by compelling evidence.

CLINICAL APPLICATION

Physical interventions can be delivered alone or as a component of other interventions. The interventions are delivered over 8 to 12 weeks. Psychological therapies are mostly delivered as a component of a multidisciplinary treatment program: cognitive behavioral therapy is most often used, and interventions usually run from 4 to 10 weeks. Pharmacological interventions should be delivered in combination with physical and psychological interventions. Tailor family-centered interventions to personal aspects, such as age, gender, and family structure. When communicating with children and adolescents, use simple language that is clear and direct. Aim to support trust between health professionals and parents to facilitate family decision making. J Orthop Sports Phys Ther 2022;52(7):419-424. Epub: 18 May 2022. doi:10.2519/jospt.2022.10768.

Prevalence and Characteristics of Back Pain in Children and Adolescents from the Region of Murcia (Spain): ISQUIOS Programme

Puberty is a vulnerable period for musculoskeletal disorders due to the existence of a wide inter-individual variation in growth and development. The main objective of the present study was to describe the prevalence of back pain (BP) in the past year and month in school-aged children according to sex, age, maturity status, body mass index (BMI) and pain characteristics. This study involved 513 students aged between 9 and 16 years. Anthropometric measures were recorded to calculate the maturity stage of the students using a regression equation comprising measures for age, body mass, body height, sitting height and leg length. An ad hoc questionnaire composed of eight questions was used to describe BP prevalence in school-aged children. The results showed that the prevalence of BP in school-aged children was observed in 35.1% over the last year (45% boys and 55% girls), and 17.3% (40.4% boys and 59.6% girls, with an association found between female sex and BP) in the last month. The prevalence of back pain in the past year and month was higher the older the students were, or the more pubertal development they had experienced. The prevalence of BP in the last year was also higher in those with overweight or obesity. After adjustment for sex, there was an association between BP and older age and higher BMI in boys and an association between BP and higher pubertal development in girls. In summary, the present study showed that the prevalence of BP was related to the maturity stage and weight of the participants, with different prevalence patterns found according to sex.

A multidisciplinary assessment of pain in juvenile idiopathic arthritis

INTRODUCTION

Pain is prevalent in juvenile idiopathic arthritis (JIA). Unknowns regarding the biological drivers of pain complicate therapeutic targeting. We employed neuroimaging to define pain-related neurobiological features altered in JIA.

METHODS

16 male and female JIA patients (12.7 ± 2.8 years of age) on active treatment were enrolled, together with age- and sex-matched controls. Patients were assessed using physical examination, clinical questionnaires, musculoskeletal MRI, and structural neuroimaging. In addition, functional magnetic resonance imaging (fMRI) data were collected during the resting-state, hand-motor task performance, and cold stimulation of the hand and knee.

RESULTS

Patients with and without pain and with and without inflammation (joint and systemic) were evaluated.  Pain severity was associated with more physical stress and poorer cognitive function. Corrected for multiple comparisons, morphological analysis revealed decreased cortical thickness within the insula cortex and a negative correlation between caudate nucleus volume and pain severity. Functional neuroimaging findings suggested alteration within neurocircuitry structures regulating emotional pain processing (anterior insula) in addition to the default-mode and sensorimotor networks.

CONCLUSIONS

Patients with JIA may exhibit changes in neurobiological circuits related to pain. These preliminary findings suggest mechanisms by which pain could potentially become dissociated from detectable joint pathology and persist independently of inflammation or treatment status.

Manual Therapy in Preadolescent Children: A Delphi Investigation of Physical Therapists in the United States

OBJECTIVE

Limited research has investigated the use of manual therapy to treat the preadolescent (0-12 years of age) population with musculoskeletal and neurological impairments. The purpose of this study was to identify the following among physical therapists holding advanced credentials in pediatrics, neurodevelopmental treatment, or manual therapy: (1) consensus regarding effective techniques in the preadolescent population, (2) differences in opinion, and (3) perceived decision-making barriers and factors regarding use of manual therapy techniques.

METHODS

Credentialed physical therapists in the United States were recruited for a 3-round Delphi investigation. An electronic survey in Round 1 identified musculoskeletal and neurological impairments and the manual techniques considered effective to treat such conditions, in addition to factors and barriers. Responses were used to create the second round, during which a 4-point Likert scale was used to score each survey item. A third round of scoring established consensus. Descriptive statistics and composite scores were calculated for each manual technique by impairment. Between-group differences were calculated using the Mann-Whitney U test with Bonferroni correction.

RESULTS

Consensus was determined for several concepts. First, neuromuscular techniques were considered effective across all impairments, and joint mobilizations (grades I-IV) were believed to be effective to treat joint and muscle and myofascial impairments. Second, visceral manipulation and craniosacral therapy were considered ineffective in treating most impairments. There was lack of consensus and clear differences of opinion regarding the use of grade V mobilizations and dry needling. Significant barriers to use of manual therapy were: lack of knowledge, lack of evidence, and fear of litigation and harming patients.

CONCLUSION

This study is an initial step for developing manual therapy guidelines, research, and educational opportunities regarding manual therapy in pediatric physical therapy.

EFFECTS OF POSTURAL EDUCATION IN ELEMENTARY SCHOOL CHILDREN: A SYSTEMATIC REVIEW

Objective:

To determine the effect of postural education on the learning and postural habits of elementary school children without physical intervention.

Methods:

We searched PubMed, Lilacs, SciELO, Cochrane, and Science Direct data bases and reference lists of studies in February 2020. The eligibility criteria were randomized clinical trials related to the effect of postural education in children aged between 6 and 12 years old. Two authors independently assessed trials for inclusion and risk of bias: randomization process, deviations from intended interventions, missing outcome data, measurement of the outcome, and selection of the reported result. Data were extracted in standardized tables including information on author, publication year, country, sample size, age, sex, intervention characteristics, outcome measurements and results.

Results:

We found seven clinical trials (involving 2,568 children) for the review. The studies were conducted between 2000 and 2018: four in Belgium, two in Spain, and one in Germany. All seven included trials underwent evaluation: only one had a clear process of randomization and allocation concealment. All included studies were judged as having high risk of bias in at least one domain or have concerns for multiple domains.

Conclusions:

The positive effects of acquired knowledge and postural habits found in the studies cannot be used to reliably support postural education in elementary school children due to a high risk of bias in the evaluated studies.

Family history of pain and risk of musculoskeletal pain in children and adolescents: a systematic review and meta-analysis

Emerging evidence suggests that musculoskeletal (MSK) pain should be viewed from a biopsychosocial perspective and consider the influence of family factors. We conducted a review with meta-analysis to provide summary estimates of effect of family history of pain on childhood MSK pain and explore whether specific family pain factors influence the strength of the association (PROSPERO CRD42018090130). Included studies reported associations between family history of pain and nonspecific MSK pain in children (age <19 years). The outcome of interest was MSK pain in children. We assessed the methodological quality using a modified version of the Quality in Prognosis Studies instrument and quality of evidence for the main analyses using the GRADE criteria. After screening of 7281 titles, 6 longitudinal and 23 cross-sectional studies were included. Moderate quality evidence from 5 longitudinal studies (n = 42,131) showed that children with a family history of MSK pain had 58% increased odds of experiencing MSK pain themselves (odds ratio [OR] 1.58, 95% confidence interval 1.20-2.09). Moderate quality evidence from 18 cross-sectional studies (n = 17,274) supported this finding (OR 2.02, 95% 1.69-2.42). Subgroup analyses showed that the relationship was robust regardless of whether a child's mother, father, or sibling experienced pain. Odds were higher when both parents reported pain compared with one ([mother OR = 1.61; father OR = 1.59]; both parents OR = 2.0). Our findings show moderate quality evidence that children with a family history of pain are at higher risk of experiencing MSK pain. Understanding the mechanism by which this occurs would inform prevention and treatment efforts.

Center of rotation locations during lumbar spine movements: a scoping review protocol

OBJECTIVE

The objective of this review is to identify and map current literature describing the center of rotation locations and migration paths during lumbar spine movements.

INTRODUCTION

Altered lumber spine kinematics has been associated with pain and injury. Intervertebral segments' center of rotations, the point around which spinal segments rotate, are important for determining the features of lumbar spine kinematics and the potential for increased injury risk during movements. Although many studies have investigated the center of rotations of humans' lumbar spine, no review has summarized and organized the state of the science related to center of rotation locations and migration paths of the lumbar spine during lumbar spine movements.

INCLUSION CRITERIA

This review will consider studies that include human lumbar spines of any age and condition (e.g. heathy, pathological) during lumbar spine movements. Quantitative study designs, including clinical, observational, laboratory biomechanical experimental studies, mathematical and computer modeling studies will be considered. Only studies published in English will be included, and there will be no limit on dates of publication.

METHODS

PubMed, MEDLINE, Embase, the Cochrane Library Controlled Register of Trials, CINAHL, ACM Digital Library, Compendex, Inspec, Web of Science, Scopus, Google Scholar, and dissertation and theses repositories will be searched. After title and abstract screening of identified references, two independent reviewers will screen the full-text of identified studies and extract data. Data will be summarized and categorized, and a comprehensive narrative summary will be presented with the respective results.

Ventrolateral disc herniation causes psoas muscle compression: A case report

We report a case of a 39-year old male patient who presented to us with several months of lower back pain. Following clinical assessment, the patient underwent a magnetic resonance imaging exam, which after using advanced imaging protocols showed a ventrolateral disc hernation toward the psoas muscle. Based upon the findings in the magnetic resonance and the electromyoneurographic examination, the decision was made to treat the patient conservatively. Coronal planes are useful for discerning changes of various origins not usually seen on the sagital and axial planes. If needed, additional advanced protocol is available for increased specificity and diagnostic accuracy.

Musculoskeletal Pain in Children and Adolescents: A Way Forward

There are substantial gaps in our understanding of musculoskeletal pain in children and adolescents. While there are challenges to performing research in this space, the prevalence, burden, and lack of available evidence to inform clinical practice mean that overcoming these challenges is important. The editors see the collection of work in this special issue as a step in the right direction. J Orthop Sports Phys Ther 2017;47(10):702-704. doi:10.2519/jospt.2017.0109.
