Pain characteristics and their association with quality of life and self-concept in children with hemiplegic cerebral palsy identified from a population register

A randomized, cross-over trial comparing the effect of innovative robotic gait training and functional clinical therapy in children with cerebral palsy; a protocol to test feasibility

PURPOSE

Robotic gait training is relatively new in the world of pediatric rehabilitation. Preliminary feasibility studies and case reports include stationary robot-assisted treadmill training. Mobile robotic gait trainers hold greater promise for intensive practice-based therapy within hospitals, schools, rehabilitation centers, and at-home therapy as they enable participation and social integration while practicing high-quality gait patterns.

MATERIALS AND METHODS

This paper (clinical trials registry number: NCT05378243) provides a detailed description of a mixed-method cross-over trial design with a broad set of outcome measures. Ultimately the goal is to establish the feasibility of this design which includes the collection of qualitative data regarding patient, family, and therapist experience and quantitative data regarding gait efficiency and quality, impact on tone, individualized goal achievement and bone strength.

Mental health and behaviour in children with dystonia: Anxiety, challenging behaviour and the relationship to pain and self-esteem

PURPOSE

To ascertain whether young people with dystonia are more likely than the general population to have mental health and/or behavioural difficulties, and to explore factors that may contribute to these difficulties.

METHOD

Using a quasi-experimental design, 50 young people with dystonia aged 7-17 and their carers were recruited from the Evelina London Children's Hospital. Young people completed the Beck Youth Inventories and the Strengths and Difficulties Questionnaire. Carers completed the Strengths and Difficulties Questionnaire-Parent version and the Paediatric Pain Profile. Important medical factors, such as age of onset, motor severity and manual function were obtained from medical records.

RESULTS

One sample z tests showed young people with dystonia self-reported significantly higher levels of anxiety (p < .001) and prosocial difficulties (p < .01), with 48% experiencing clinically significant anxiety levels. They experienced significantly lower levels of anger, disruptive behaviour and conduct problems (all p ≤ .01). Carers reported significantly higher rates of emotional problems, hyperactivity and peer problems, and significantly lower prosocial behaviours (all p ≤ .01). Pearson's correlation coefficients showed lower levels of self-esteem were related to higher levels of anxiety (p = .015). High levels of pain were related to parent-rated conduct problems (p = .004). Age of dystonia onset and motor severity did not correlate with any of the psychological or behavioural measures.

INTERPRETATION/CONCLUSIONS

Our study suggests high rates of anxiety and behaviours that challenge in children with dystonia. Screening in movement clinics would be helpful in early identification and signposting for support.

Determinants of sleep problems in children with intellectual disability

Children with intellectual disabilities are more likely to experience sleep disorders of insomnia, excessive daytime sleepiness and sleep breathing disorders than typically developing children. The present study examined risk factors for these sleep disorders in 447 children (aged 5-18 years), diagnosed with an intellectual disability and comorbid autism spectrum disorder, cerebral palsy, Down syndrome or Rett syndrome. Primary caregivers reported on their child's sleep using the Sleep Disturbance Scale for Children (SDSC), as well as medical comorbidities and functional abilities. Multivariate linear and logistic regressions were used to examine the effects of these factors on SDSC t scores and a binary indicator, respectively for the relevant subscales. Receiving operating characteristic curves were generated for each logistic regression model to determine their ability to discriminate between poor and good sleep. Comorbidities rather than functional abilities were associated with poorer sleep. In particular, recurrent pain, frequent seizures, frequent coughing, constipation and prescription of sleep medications were associated with abnormal sleep across the entire sample, but predictors differed between diagnostic groups. The present study suggests that comorbidities are more strongly associated with quality of sleep than functional impairments. The present study provides new information on potential associations between frequent coughing, prescription sleep medications and sleep quality that should be further investigated.

Clinical Factors Associated With Chronic Pain in Communicative Adults With Cerebral Palsy: A Cross-Sectional Study

Chronic pain is prevalent in adults with cerebral palsy. We aimed to explore associations between chronic pain and somatosensory, motor, cognitive, etiologic, and environmental factors in adults with cerebral palsy. This cross-sectional study enrolled 17 adult participants with cerebral palsy (mean age 31 years; 8 female; Gross Motor Functional Classification Status levels I-V) able to self-report and 10 neurotypical adult volunteers (mean age 34 years; 9 female). Participants reported pain characteristics, demographics, and affective factors. Physical examination included somatosensory and motor evaluation. Between-group comparisons used a ranksum test, and correlation analyses estimated effect size in terms of shared variance (ρ²). Individuals with cerebral palsy reported greater pain intensity, neuropathic qualities, and nociceptive qualities than control participants. Higher pain intensity was associated with female gender (ρ² = 16%), anxiety/depression symptoms (ρ² = 10%), and lower household income (ρ² = 19%). It was also associated with better communicative ability (ρ² = 21%), spinothalamic (sharp/temperature) sensory abnormalities (ρ² = 33%), and a greater degree of prematurity (ρ² = 17%). This study highlights similarity of chronic pain associations in people with cerebral palsy with patterns seen in other populations with chronic pain. Spinothalamic sensory abnormalities suggest central pain mechanisms.

Effect of pain on mood affective disorders in adults with cerebral palsy

AIM

To determine if pain is associated with 12-month incidence of mood affective disorders (MAD) in adults with cerebral palsy (CP).

METHOD

Data from Optum Clinformatics^® Data Mart (2013-2016) were used for this retrospective cohort study. Diagnostic codes were used to identify adults (≥18y) with CP, incident cases of MAD, and covariates (other neurodevelopmental conditions, sleep disorders, arthritis). Pain (any type, location) was identified between 1st October 2014 and 30th September 2015. The pain group was divided into new or consistent pain if they had a history of pain (i.e. consistent) in the 12 months before their first pain claim date. Crude incidence rates of MAD (expressed per 100 person-years) were estimated. Cox regression was used to estimate hazard ratio (95% confidence interval [CI]) of MAD after adjusting for covariates.

RESULTS

Adults that had new pain (n=859; incidence rate=15.5) or consistent pain (n=1303; incidence rate=17.9) had greater crude incidence rate of MAD compared to adults without pain (n=3726; incidence rate=5.9). The elevated rate of MAD remained after adjusting for covariates, for new pain (hazard ratio=2.4; 95% CI=1.9-3.0) and consistent pain (hazard ratio=2.1; 95% CI=1.7-2.7).

INTERPRETATION

Pain is associated with greater incidence of MAD in adults with CP. This association remained after accounting for potential confounding factors.

WHAT THIS PAPER ADDS

What this paper adds Pain was associated with higher 12-month incidence of mood affective disorders (MAD). The 12-month MAD incidence was similar between new and consistent pain groups. The MAD incidence remained higher adjusting for neurodevelopmental comorbidities, sleep disorders, and arthritis.

A prospective study investigating gross motor function of children with cerebral palsy and GMFCS level II after long-term Botulinum toxin type A use

BACKGROUND

The aim of this study is to contribute to the knowledge base on the long-term outcomes of evidence-based medical interventions used to improve gross motor function in children and adolescents with Cerebral Palsy.

METHOD

Prospective cohort study of children with Cerebral Palsy in the birth years 2000-2009 attending a tertiary level service for children with Cerebral Palsy who's first recorded Gross Motor Function Classification System level was II.

RESULTS

A total of 40 children were eligible for the study, of whom 28 (72.7%) enrolled. The Botulinum toxin A treatment for this cohort, (median and interquartile ranges) were: total number of lower limb Botulinum toxin A injections 11 (6.7, 5.5); total dose of Botulinum Toxin A per lower limb treatment 6.95 u/kg (4.5, 11); and dose of Botulinum Toxin u/kg/muscle 2.95 (2.2, 4). For all 28 subjects there was a median of 15 (8.5 to 22) Gross Motor Function Classification System level recordings: six of the 28 children (21.4%) improved from level II to level I, the remaining 22 children remained stable at level II (78.6%). In this highly treated population, the average 66 item Gross Motor Function Measure score for the 22 children in level II was 72.55, which is consistent with the mean of 68.5 reported in the original Ontario cohort.

CONCLUSION

This cohort study has confirmed that children with Cerebral Palsy, Gross Motor Function level II treated at a young age with repeated doses of Botulinum Toxin A within an integrated comprehensive service, maintain or improve their functional motor level at a later age.

Community-Based Upper Extremity Power Training for Youth with Cerebral Palsy: A Pilot Study

Aim: To examine the effects of an upper-extremity, community-based, and power-training intervention.Methods: Twelve participants with cerebral palsy (CP) [8 males, 4 females; mean age 14 years 6 months (SD 5 years 4 months), range 7-24] were randomly assigned to a rest-training (RT; n = 6) or training-rest (n = 6) group in this randomized, cross-over design. Training took place in participants' home or school, three times per week for 6 weeks. We examined changes in upper extremity average power output (Pavg) in watts (W) and changes in function via the Pediatric Outcomes Data Collection Instrument (PODCI).Results: Each participant completed at least 15 of the 18 total training sessions (91.2% adherence). Pavg increased 92.2% on average among participants (p < .05). There was a significant three-way interaction among treatment, sequence, and period with the data stratified by (Bimanual Fine Motor Function [BFMF]) level on the pain subscale of the PODCI (p = 0.0118). All participants decreased pain after training with the exception of individuals with lower functioning (BFMF II-V) in the RT group.Conclusion: A community-based upper extremity power-training intervention was feasible and effective at improving power among young people with CP and has the potential to improve pain.

Prevalence, identification, and interference of pain in young children with cerebral palsy: a population-based study

OBJECTIVE

To explore the presence of pain, how pain was addressed by physicians and parents, and how pain affected everyday life in young children with cerebral palsy (CP).

METHODS

Children with CP, aged 5-10 years, participated in this cross-sectional study. Data were collected from medical records spanning a period of two years and by a standardized parental interview that included six structured questions and the Pain Interference Index.

RESULTS

A total of 118 children, with a mean age of 7.4 years (SD 1.5), participated in the study. The parents of 81% of these children were interviewed. Pain was reported in 52% of the children, and pain was present at all severity levels. The prescription of analgesics was documented in 25% of these children's medical records. Fifty-nine percent of the children with pain received analgesics from their parents. Pain restricted the children's everyday lives particularly concerning sleep, school work and being with friends.

CONCLUSIONS

Half of this group of young children with CP were reported to have pain. Pain restricted the children's everyday lives and seemed to be under-treated. If pain can be addressed early, the children's everyday lives are likely to be improved.Implications for rehabilitationThere is a need to early identify and treat pain in young children.Important to discuss pain with parents irrespectively of the child's age and severity level.Pain interference assessment gives valuable information.Early treatment of pain might improve children's everyday life.

Clinical factors associated with mood affective disorders among adults with cerebral palsy

Objective

To determine individual and aggregated associations of cerebral palsy (CP)-related symptoms and the effect of comorbid neurodevelopmental conditions on mood (affective) disorders among adults with CP.

Methods

Cross-sectional data from 2016 were extracted from a random 20% sample of the Medicare fee-for-service database. International Classification of Diseases, Tenth Revision, Clinical Modification diagnosis codes were used to identify 18- to -64-year-old beneficiaries with CP, as well as mood (affective) disorders, pain, sleep disorders, fatigue, and comorbid neurodevelopmental conditions (intellectual disabilities [ID], autism spectrum disorders [ASD], and epilepsy).

Results

Four thousand eight hundred twenty-three of the 17,212 adults with CP had mood (affective) disorders (28.0%). After adjusting for age, sex, and race, pain (odds ratio [OR] = 2.15; 99.5% confidence interval [CI] = 1.94-2.39), sleep disorders (OR = 2.43; 99.5% CI = 2.13-2.77), fatigue (OR = 1.38; 99.5% CI = 1.18-1.60), ID (OR = 1.47; 99.5% CI = 1.31-1.63), ASD (OR = 1.44; 99.5% CI = 1.16-1.80), and epilepsy (OR = 0.81; 99.5% CI = 0.73-0.91) were each associated with mood (affective) disorders. When pain, sleep disorders, and fatigue were presented as a count variable, the adjusted odds of mood (affective) disorders increased with the number of factors: 1 factor (OR = 1.99; 99.5% CI = 1.79-2.22), 2 factors (OR = 4.18; 99.5% CI = 3.58-4.89), and all 3 factors (OR = 7.38; 99.5% CI = 5.17-10.53).

Conclusions

Among young and middle-aged adults with CP, mood (affective) disorders were associated with pain, sleep disorders, and fatigue, and increasing co-occurrence of these factors further increased the likelihood of mood (affective) disorders. Further, comorbid neurodevelopmental conditions were also associated with mood (affective) disorders among adults with CP. Study findings could be used to improve screening strategies for mood (affective) disorders among adults with CP in the clinical setting.

Mental health disorders, participation, and bullying in children with cerebral palsy

AIM

To examine how social factors might mitigate the elevated risk of mental health disorders in children with cerebral palsy (CP).

METHOD

This cross-sectional study included 6- to 17-year-olds with (n=111; 40.4% 6-11y, 59.6% 12-17y) and without (n=29 909; 50.2% 6-11y, 49.8% 12-17y) CP from the 2016 National Survey of Children's Health. Mental health disorders included depression, anxiety, behavior/conduct problems, and attention-deficit/hyperactivity disorder. Social factors included participation in activities, bully victimization, and difficulty with friendships.

RESULTS

After adjusting for sociodemographic factors and the presence of chronic pain, children with CP had higher odds of anxiety (odds ratio [OR] 4.4; 95% confidence interval [CI] 1.9-8.5), behavior/conduct problems (OR 3.9; 95% CI 1.4-11.3), and multimorbidity (OR 2.8; 95% CI 1.1-7.0), but not depression (OR 1.4; 95% CI 0.6-3.8) or attention-deficit/hyperactivity disorder (OR 1.7; 95% CI 0.6-4.6), compared to controls. With adjustment for participation in activities, the odds of anxiety, behavior/conduct problems, and multimorbidity remained increased in children with CP. With adjustment for difficulty with friendships, the odds of anxiety, behavior/conduct problems, and multimorbidity were no longer increased in children with CP. With adjustment for bully victimization, the odds of behavior/conduct problems and multimorbidity were attenuated in children with CP; however, the odds of anxiety remained increased.

INTERPRETATION

The elevated prevalence of certain mental health disorders in children with CP is partly associated with modifiable social factors.

WHAT THIS PAPER ADDS

Difficulty with friendships predicts an elevated prevalence of psychiatric conditions in children with cerebral palsy (CP). Bully victimization predicts an elevated prevalence of behavior/conduct problems in children with CP. Low participation does not predict mental health disorders in this population.

Post-Operative Pain Assessment and Management in Cerebral Palsy (CP): A Two-Pronged Comparative Study on the Experience of Surgical Patients

INTRODUCTION

This study compares the current practice patterns of pain assessment and management between children with and without CP following either posterior spinal instrumentation and fusion (PSIF) or hip osteotomy (HO).

METHODS

Two cohorts of CP patients were retrospectively identified and matched with non-CP patients based on age, surgical procedure, and approach to post-operative pain management. Sixteen CP patients undergoing PSIF and twenty-two undergoing HO were respectively matched with the same numbers of non-CP patients receiving the same procedures. The frequency of assessments conducted, highest pain scores recorded on each post-operative day (POD), and the amount of adjuvant analgesics administered were collected for POD 0-4.

RESULTS

Patients with CP were significantly more frequently evaluated for pain post-operatively, tended to have lower pain scores as measured by current scales, and received slightly fewer analgesics. Patients with CP differed from their non-CP counterparts in both frequency and method of post-operative pain assessment.

CONCLUSIONS

The purpose of this study is to elucidate the current state of post-operative pain assessment and management in children with CP undergoing major orthopaedic surgeries, to improve CP patient/caregiver understanding and expectation of the post-operative experience regarding pain, and to provide recommendations for improving the post-operative care for these patients.

Mental health disorders and physical risk factors in children with cerebral palsy: a cross-sectional study

AIM

To examine the prevalence of mental health disorders among children with and without cerebral palsy (CP), and to examine how physical risk factors in children with CP might mitigate any elevated risk of mental health disorders in this population.

METHOD

Children from 6 years to 17 years of age with (n=111) and without (n=29 909) CP from the 2016 National Survey of Children's Health were included in this cross-sectional study. Mental health disorders included depression, anxiety, behavior/conduct problems, and attention deficit disorder/attention-deficit/hyperactivity disorder (ADHD). Physical risk factors included physical activity (number of active days ≥60min), sleep duration, and pain.

RESULTS

Adjusting for sociodemographics, children with CP had higher odds of mental health disorders (odds ratio [OR]=2.7-7.1, p<0.05) except for attention deficit disorder/ADHD (OR=2.5; 95% confidence interval [CI]=0.9-7.1). Further adjusting for physical factors, the odds of depression were no longer increased (i.e. attenuated) in children with CP (OR=1.0; 95% CI=0.3-3.3); however, the odds of anxiety (OR=3.8; 95% CI=1.9-7.8) and behavior/conduct problems (OR=3.8; 95% CI=1.3-11.1) remained elevated. Assessed individually, low physical activity and pain attenuated the odds of depression in children with CP (OR=1.9; 95% CI=0.7-5.3; OR=1.4; 95% CI=0.6-3.8 respectively).

INTERPRETATION

Children with CP have an elevated prevalence of mental health disorders even after accounting for physical risk factors. Low physical activity and pain partially accounts for the association between CP and depression.

WHAT THIS PAPER ADDS

Children with cerebral palsy (CP) have an elevated risk of developing mental health disorders. Physical factors do not fully account for higher mental health disorder prevalence. Physical activity partially accounts for the relationship between CP and depression. Pain partially accounts for the relationship between CP and depression.

Prevalence and characteristics of pain in children and young adults with cerebral palsy: a systematic review

AIM

The primary aim of this review is to evaluate the evidence for pain prevalence in children and young adults with cerebral palsy. Secondary aims are to identify pain characteristics and types of pain measurement used in this population.

METHOD

Ovid MEDLINE, Embase, CINAHL Plus, and PubMed were searched in October 2016 and updated in November 2017. Two authors independently screened studies according to Preferred Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Pain outcomes were categorized within a biopsychosocial pain framework, with pain prevalence extracted for all recall periods and measurement types.

RESULTS

One hundred and six publications from 57 studies met inclusion criteria. Pain prevalence varied widely from 14 per cent to 76 per cent and was higher in females, older age groups, and those classified within Gross Motor Function Classification System level V. Pain was most frequent in the lower limbs, back, and abdomen and associated with reduced quality of life or health status. The influence of pain on psychological functioning, interference, and participation was inconclusive.

INTERPRETATION

Variation exists in reported pain prevalence because of sampling bias, inconsistent measurement, varying recall periods, and use of different participant age ranges.

WHAT THIS PAPER ADDS

Pain prevalence varies from 14 per cent to 76 per cent in children and young adults with cerebral palsy. Pain is more prevalent in females, older age groups, and children in Gross Motor Function Classification System level V.

Analgesic Effects of Botulinum Toxin in Children with CP

Experiencing pain is the greatest contributor to a reduced quality of life in children with cerebral palsy (CP). The presence of pain is quite common (~60%) and increases with age. This leads to missed school days, less participation, and reduced ambulation. Despite these alarming consequences, strategies to relieve the pain are absent and poorly studied. Moreover, it is difficult to evaluate pain in this group of children, especially in cases of children with cognitive deficits, and tools for pain evaluation are often inadequate. Botulinum toxin has been shown to alleviate pain in a variety of disorders and could potentially have an analgesic effect in children with CP as well. Even though most of the studies presented here show promising results, many also have limitations in their methodology as it is unlikely to capture all dimensions of pain in this heterogeneous group using only one assessment tool. In this review, we present a new way of examining the analgesic effect of botulinum toxin in children with CP using a variety of pain scores.

Prevalence and factors associated with sleep disorders among children with cerebral palsy in Uganda; a cross-sectional study

Background

Sleep plays a prominent role in the growth and development of children. Children with cerebral palsy (CP) are more prone to sleep disorders (SDs) than their peers. Children with CP, have a higher prevalence of disorders involving; initiation and maintenance of sleep, sleep-wake transition, excessive sleepiness and arousal. These sleep disorders impact on the quality of life of these children. Despite, having a high prevalence of CP in Uganda, there is a paucity of data that focuses on sleep disorders in CP, including a lack of prevalence estimates of sleep breathing disorder (SBD) in CP. Understanding the prevalence and disorders of sleep within this population would help advise on the development of tailored interventions to address the needs of these children and improve their quality of life. This study determined the prevalence and associated factors of sleep disorders among children aged 2 – 12 years with cerebral palsy in Uganda.

Methods

This was a cross sectional study. All participants had a physical examination and screening with the Sleep Disturbances Scale for Children (SDSC) questionnaire to determine the prevalence of sleeps disorders. A total score (TS) ≥ 51 on the Sleep Disturbances Scale for Children was regarded as abnormal.

Results

A total of 135 participants were recruited. The prevalence of sleep disorders was 43/135 (32%) with 95% CI: (24.0-39.7). The most common type of sleep disorders was a disorder of initiating and maintaining sleep 37(27%). The factors associated with sleep disorders among children with cerebral palsy were bilateral spasticity (p = 0.004); OR:(95%CI), 11.193: (2.1 – 59.0), lowest levels of gross motor function V (p = < 0.001); OR:(95%CI), 13.182: (3.7 – 47.0) or IV (p = 0.007); OR:(95%CI), 12.921: (2.0 – 82.3), lowest level of manual ability V (p = 0.004); OR:(95%CI), 11.162: (2.2 – 56.4) and presence of epilepsy (p = 0.011); OR:(95%CI), 3.865: (1.4 – 10.9).

Conclusions

The prevalence of sleep disorders among children with cerebral palsy in Uganda is high. Severe disability and presence of epilepsy were associated with sleep disorders among children with cerebral palsy.

The effect of supported physical activity on parental-reported sleep qualities and pain severity in children with medical complexity

PURPOSE

To study the impact of a 5-week supported physical activity (PA) intervention on parental report of sleep qualities, sleep duration, and pain severity in children with medical complexity (CMC).

METHODS

Twenty-nine CMC participated in 180 minutes of daily supported PA on weekdays over 5 weeks. A pre- and post-test design was used to collect sleep qualities (Children's Sleep Habits Questionnaire) and pain severity (Faces Pain Scale- Revised) as reported by parents. Using a repeated measures design, weekly sleep diaries captured sleep duration.

RESULTS

Children with medical complexity experienced no adverse effects, including pain, with the supported PA intervention. Significant improvements in sleep problems, sleep duration, and pain severity (P< 0.05) were demonstrated.

CONCLUSION

Short-term supported PA did not interfere with sleep or pain in CMC, and in fact, seems to have enhanced parental report of sleep qualities, sleep duration, and pain severity. Supported PA appears safe for CMC and healthcare professionals should explore methods to expand opportunities for supported PA participation.

Parent-reported pain in non-verbal children and adolescents with cerebral palsy

AIM

This cross-sectional study aimed to determine the prevalence, frequency, and intensity of parent-reported pain among non-verbal children with cerebral palsy (CP) and explore associations with medical, demographic, and parental psychosocial factors.

METHOD

Participants were parents of non-verbal outpatients (aged 2-20y) with CP at University of Malaya Medical Centre, Kuala Lumpur and two community centres. Parents answered the Caregiver Priorities and Child Health Index of Life with Disabilities Questionnaire and a pro forma regarding parent-reported frequency and intensity of pain during the preceding 4 weeks. Parental psychosocial well-being was assessed via the Depression, Anxiety and Stress Scale and Multidimensional Scale of Perceived Social Support.

RESULTS

The response rate was 94%; 104 children (54 males, 50 females) were studied. The majority (51%) were in Gross Motor Function Classification System level V and 65% had spastic quadriplegia. Parents reported pain in 65%, intense pain in 17%, and daily pain in 28%. Intense and frequent pain was reported during physiotherapy. More intense pain was reported in older children (p=0.016) and those with spastic quadriplegia (p=0.020).

INTERPRETATION

Caregivers of non-verbal children with CP report a high frequency of pain. Pain intensity is associated with patient factors but not parental psychosocial factors.

Investigating the impact of pain, age, Gross Motor Function Classification System, and sex on health-related quality of life in children with cerebral palsy

AIM

To explore whether health-related quality of life (HRQOL) can be predicted by pain, age, Gross Motor Function Classification System (GMFCS) level, and sex in children with cerebral palsy (CP) and whether different pain etiologies have varying effects on HRQOL.

METHODS

Children with CP aged 3 to 19 years and their caregivers were consecutively recruited. Caregivers reported their child's pain (Health Utilities Index 3 [HUI3] pain subset) and HRQOL (DISABKIDS questionnaires). Physicians identified pain etiologies. A multiple linear regression model determined whether pain, GMFCS level, sex, and age predicted HRQOL. An ANOVA evaluated the effects of pain etiologies on HRQOL.

RESULTS

Three hundred and forty-four participants were approached and 87% (n=300) participated. Sufficient data were available on 248 (72% of total sample). Sixty-six participants (27%) formed the pain group with HUI3 pain scores of at least 3. The presence of pain and increasing age significantly negatively predicted HRQOL (p<0.001, R(2) =0.141), while GMFCS and sex did not. Musculoskeletal deformity (24%) and hypertonia (18%) were the most frequent pain causes. HRQOL statistically differed depending on the pain etiology (p=0.028) with musculoskeletal deformity showing the lowest mean HRQOL.

INTERPRETATION

The presence of pain and increasing age negatively predict HRQOL in CP. musculoskeletal deformity has the greatest negative impact on HRQOL.

Chronic Pain Assessment Tools for Cerebral Palsy: A Systematic Review

BACKGROUND AND OBJECTIVE

Chronic pain in children with cerebral palsy (CP) is underrecognized, leading to detriments in their physical, social, and mental well-being. Our objective was to identify, describe, and critique pediatric chronic pain assessment tools and make recommendations for clinical use for children with CP. Secondly, develop an evidence-informed toolbox to support clinicians in the assessment of chronic pain in children with disabilities.

METHODS

Ovid Medline, Cumulative Index to Nursing and Allied Health Literature, and Embase databases were systematically searched by using key terms "chronic pain" and "clinical assessment tool" between January 2012 and July 2014. Tools from multiple pediatric health conditions were explored contingent on inclusion criteria: (1) children 1 to 18 years; (2) assessment focus on chronic pain; (3) psychometric properties reported; (4) written in English between 1980 and 2014. Pediatric chronic pain assessment tools were extracted and corresponding validation articles were sought for review. Detailed tool descriptions were composed and each tool underwent a formal critique of psychometric properties and clinical utility.

RESULTS

Of the retrieved 2652 articles, 250 articles met eligibility, from which 52 chronic pain assessment tools were retrieved. A consensus among interprofessional working group members determined 7 chronic pain interference tools to be of importance. Not all tools have been validated with children with CP nor is there 1 tool to meet the needs of all children experiencing chronic pain.

CONCLUSIONS

This study has systematically reviewed and recommended, through expert consensus, valid and reliable chronic pain interference assessment tools for children with disabilities.

Hip reconstruction is more painful than spine fusion in children with cerebral palsy

PURPOSE

Concerns about pain control in patients with cerebral palsy (CP) are especially anxiety provoking for parents, given the fact that spasticity, communication issues, and postoperative muscle spasms are significant problems that make pain control difficult in these patients. A better understanding of the magnitude and quality of the pain these patients experience after our surgical procedures would better prepare the patients and their families. The purpose of this study is to quantify the amount of postoperative pain in children with CP undergoing hip reconstruction and spinal fusion. Specifically, the study will compare pain scores and the amount of narcotics used between the two groups.

MATERIALS AND METHODS

This is a retrospective chart review of a consecutive series of children with CP (GMFCS levels IV and V) over a 5-year period undergoing hip reconstruction (femoral osteotomy, pelvic osteotomy, or both) and posterior spinal fusion (PSF) at a tertiary-care pediatric hospital. The primary end point was the total opioid used by the patient during the hospitalization, by converting all forms of narcotics to morphine equivalents. The secondary end point was the documentation of pain with standard pain scores at standard time points postoperatively. Adverse effects related to pain management were documented for both groups. Student's t-tests were utilized to statistically compare differences between the groups, with significance determined at p < 0.05.

RESULTS

Forty-two patients with CP who underwent hip reconstruction (mean age 8.8 years) were compared to 26 patients who underwent PSF (mean age 15.4 years). The total opioid used, normalized by body weight and by days length of stay (DLOS), in the hip group was 0.49 mg morphine/kg/DLOS, compared to 0.24 for the spine group (p = 0.014). The mean pain score for the hip group was 1.52, compared to 0.72 for the spine group (p = 0.013). There were no significant differences in the occurrence of adverse effects related to pain management between the two groups.

CONCLUSION

Patients with CP undergoing hip reconstruction surgery had significantly more pain, as exhibited by requiring more narcotics and having higher pain scores, than those patients undergoing PSF. The knowledge that hip reconstruction is more painful than PSF for patients with CP will better prepare families about what to expect in the postoperative period and will alert providers to supply better postoperative pain control in these patients.

Sleep disorders in children with cerebral palsy and its correlation with sleep disturbance in primary caregivers and other associated factors

AIMS

To observe prevalence of sleep disturbance (SD) in cerebral palsy (CP) children in a specific age-group and its correlation with SD in primary caregivers and other associated factors.

MATERIALS AND METHODS

This was a prospective cross-sectional study. SD assessed using Sleep Disturbance Scale for Children (SDSC) in CP children and Pittsburgh Sleep Quality Index (PSQI) in caregivers. Fifty cases of clinically diagnosed CP [27 females, mean age: 107.9 ΁ 29.5 months (range: 78-180 months)] fulfilling criteria were included.

RESULTS

Eighteen (36%) children had pathological sleep total score (TS) and Disorders of Initiating and Maintaining Sleep (DIMS) was the commonest SD (n = 25, 50%). All primary caregivers were mothers. Twenty-five (50%) mothers had SD on PSQI scale. DIMS, Disorders of Excessive Somnolence (DES), and TS had significant correlation with PSQI (P < 0.05). Disorders of Arousal (DA) and TS had significant correlation with seizures (P < 0.05) in CP children. Bed-sharing had significant correlation with SD in caregivers (P < 0.001) but not with CP children. No significant correlation was observed between SD in CP and gross motor function (Gross Motor Function Classification System), use of orthoses, and dental caries.

INTERPRETATION

Children with CP have underreported significant SD, which negatively impacts caregiver's sleep also. Seizure disorders and medications contribute significantly to SD.

Are We Undermedicating Patients With Neuromuscular Scoliosis After Posterior Spinal Fusion?

STUDY DESIGN

Retrospective, matched study of patients with adolescent idiopathic scoliosis (AIS) and patients with cerebral palsy (CP) undergoing (PSF).

OBJECTIVES

To compare pain management, through measurement of the amount of narcotic used and pain scores, for patients with neuromuscular (NM) scoliosis undergoing PSF to a cohort of patients with AIS.

SUMMARY OF BACKGROUND DATA

Posterior spinal fusion for children with severe NM scoliosis carries a high risk of complications. Appropriate assessment of pain is crucial; undertreatment of pain leads to anxiety whereas overtreatment can lead to respiratory depression and additional complications.

METHODS

A series of patients with NM scoliosis was matched for age, gender, and weight with a group of patients with AIS. Data collection included age, curve type and magnitude, and instrumentation type and levels fused. The total opioid used (TOU) was determined by summing all narcotics given during the hospital stay and converting them to morphine equivalent units. The data were then analyzed to determine differences in TOU.

RESULTS

A total of 25 patients with NM scoliosis were included in the study. This group was matched with 25 patients with AIS scoliosis. The TOU for the NM group was 1.2 mg morphine/kg (range, 0.28-4.21 mg morphine/kg) whereas the TOU for the AIS group was 3.52 mg morphine/kg (range, 0.71-15.51 mg morphine/kg) (p < .0000001).

CONCLUSIONS

In this case-control analysis, patients with AIS undergoing PSF received more than twice the amount of narcotic compared with a matched group of patients with NM scoliosis. These data suggest that NM patients' pain may be undertreated compared with AIS patients. More study is indicated to investigate pain assessment and pain control in this vulnerable patient population to improve care.

Pain, motor function and health-related quality of life in children with cerebral palsy as reported by their physiotherapists

Background

Children and adolescents with cerebral palsy suffer from higher levels of pain than their peers without disability. The aim of this study was to explore the impact of pain on health-related quality of life and motor function in individuals with cerebral palsy as reported by health professionals.

Methods

Cross-sectional study carried out in Associations for Care of Individuals with Cerebral Palsy and Related Disabilities (ASPACE) in Balearic Islands and Castile Leon (Spain). Thirty-five physiotherapists rated pain, health-related quality of life and motor function in 91 children and adolescents with cerebral palsy [8-19y]. A semi-structured interview was used to collect demographic and clinical data according with the Study of Participation of Children with Cerebral Palsy Living in Europe (SPARCLE).

Results

Physiotherapists reported that 51% of individuals with cerebral palsy suffered from pain. Physiotherapists also perceived that pain in individuals with cerebral palsy was responsible for reductions of psychological but not physical domains of health-related quality of life. According with physiotherapists’ estimations, motor impairment scores were not correlated with pain scores in individuals with cerebral palsy, but they were significantly associated with physical and autonomy domains of health-related quality of life.

Conclusions

These findings highlighted the importance of assessing and providing interventions for pain relief in persons with cerebral palsy even at an early age.

Therapy management of the upper limb in children with cerebral palsy: a cross-sectional survey

PURPOSE

To establish perceived severity of upper limb (UL) impairments and their therapeutic management in children with cerebral palsy (CP).

METHODS

A cross-sectional questionnaire survey was mailed to all 208 paediatric physiotherapists (PTs) and occupational therapists (OTs) working in a region of the UK. Data analysis included descriptive statistics, frequency counts and chi-square tests.

RESULTS

A 74% response rate was achieved, of which 94 questionnaires were valid for analysis. Many impairments were rated as affecting the UL to a moderate or great extent. Goniometry and manual muscle testing were frequently reported for measuring UL impairment and by significantly more PTs than OTs. UL activity measures were rarely reported as being available or used by therapists. Participants frequently reported using positioning, neurodevelopmental therapy and task practice to treat UL dysfunction.

CONCLUSIONS

UL management in children with CP could be enhanced by application of standardized measurement tools and evidence-based interventions.

Clinical prognostic messages from a systematic review on cerebral palsy

OBJECTIVE

To summarize evidence on the rates of co-occurring impairments, diseases, and functional limitations with cerebral palsy into succinct clinical messages.

METHODS

A search was conducted of the databases PubMed, Medline, CINAHL, and PsycINFO, and the results were supplemented with hand searches. Two independent reviewers determined whether retrieved abstracts met the following inclusion criteria: human subjects; >90% were children or adults with cerebral palsy; published after 1999; and population-based data. Articles were appraised, analyzing design, participants, level of evidence, rates of impairments, and functional implications. Methodologic quality was rated by using a standardized checklist.

RESULTS

A total of 1366 papers were identified in the search; 82 were appraised and 30 were included in the meta-analyses. High-level evidence existed, as rated on the Oxford 2011 LEVELS OF EVIDENCE: 97% of prevalence studies were level 1. The data were of a moderate to high quality grade (with the exception of sleep disorders), allowing plain English clinical messages to be developed.

CONCLUSIONS

Among children with cerebral palsy, 3 in 4 were in pain; 1 in 2 had an intellectual disability; 1 in 3 could not walk; 1 in 3 had a hip displacement; 1 in 4 could not talk; 1 in 4 had epilepsy; 1 in 4 had a behavior disorder; 1 in 4 had bladder control problems; 1 in 5 had a sleep disorder; 1 in 5 dribbled; 1 in 10 were blind; 1 in 15 were tube-fed; and 1 in 25 were deaf.

Characteristics of recurrent musculoskeletal pain in children with cerebral palsy aged 8 to 18 years

AIM

The aim of this study was to explore the prevalence, predictors, severity, and impact of recurrent musculoskeletal pain in children and adolescents with cerebral palsy (CP).

METHOD

One hundred and fifty-three participants (81 males, 72 females) aged 8 to 18 years were assessed by clinical examination, interview, and questionnaires. CP type distribution was 38% unilateral spastic, 55% bilateral spastic, 6% dyskinetic, and 1% ataxic. Gross Motor Function Classification System (GMFCS) levels were as follows: level I, 54; level II, 56; level III, 20; level IV, 8; and level V, 15. Sixty-four children and 89 parents recorded pain on the Child Health Questionnaire, 56 children and 85 parents indicated impact of pain on 0 to 10 numeric rating scales, and 72 children indicated pain intensity on the Faces Pain Scale-Revised.

RESULTS

Ninety-five (62%) children across all GMFCS levels experienced recurrent musculoskeletal pain. Age above 14 years was the only significant predictor (OR 2.90, 95% CI 1.22-7.80, p=0.02, adjusted for sex, CP type, gross motor function and mother's education). Children reported recurrent musculoskeletal pain to be moderate. Parents reported pain to be more severe and with higher impact on sleep than their children did. Children and parents reported similar impact of pain on general activity and walking.

INTERPRETATION

Recurrent musculoskeletal pain is the dominating pain problem in children and adolescents with CP. Monitoring of musculoskeletal pain should be part of the medical follow-up across the whole range of motor impairment.

Tactile assessment in children with cerebral palsy: a clinimetric review

This review evaluates the clinimetric properties of tactile assessments for children with cerebral palsy. Assessment of registration was reported using Semmes Weinstein Monofilaments (SWMs) or exteroception. Assessment of two-point discrimination was reported using the Disk-Criminator® or paperclip methods; Single point localization and double simultaneous were reported from the Neurosensory Motor Developmental Assessment (NSMDA); graphaesthesia was reported from the Sensory Integration and Praxis Test (SIPT); and stereognosis was assessed using Manual Form Perception from the SIPT and the Klingels method (Klingels, K. et al. (2010). Upper limb motor and sensory impairments in children with hemiplegic cerebral palsy. Can they be measured reliably? Disability and Rehabilitation, 32(5), 409-416) and the Cooper method (Cooper, J., Majnemer, A., Rosenblatt, B., & Birnbaum, R. (1995). The determination of sensory deficits in children with hemiplegic cerebral palsy. Journal of Child Neurology, 10, 300-309). The SIPT and NSMDA demonstrated stronger content validity. Inter-rater reliability was excellent for SIPT (ICC = 0.99) and exteroception (k = 0.88). Test-retest reliability was excellent for exteroception (k = 0.89) and stereognosis (ICC = 0.86; 100%), moderate for SIPT (r = 0.69-0.74) and poor for SWM (k = 0.22). Together these assessments measure tactile registration and spatial perception. Temporal and textural tests are to be developed for comprehensive tactile examination.

Common medical comorbidities associated with cerebral palsy

The medical issues associated with the diagnosis of cerebral palsy (CP) can have significant interplay with the neuromuscular issues that most physiatrists manage in the clinical setting. Identification and appropriate management of these common comorbidities by the primary care and subspecialist physicians can have significant impact on the quality of life of the patient and family. Some of these issues are prevalent across all gross motor function classification system (GMFCS) levels of severity, whereas others more commonly complicate the care of those children with the more severe GMFCS levels IV and V. Performance of a complete review of systems to address the potentially complex medical comorbidities and subsequent application of appropriate screening tools can assist in achieving optimal outcomes in children with CP and their families.

Upper limb orthoses and assistive technology utilization in children with hemiplegic cerebral palsy recruited from a population register

OBJECTIVE

To describe the use of upper limb orthoses and assistive technologies (AT) in a representative community-based sample of children with hemiplegic cerebral palsy (HCP) and compare children on the basis of their prescription.

METHOD

Survey of all children with HCP entered on a population register. Outcome measures included a clinical examination; Assessment of Motor and Process skills; Self-perception Profile for Children; PedsQL version 4; Paediatric Evaluation of Disability Inventory.

RESULTS

Of 107 respondents, 56% were prescribed upper limb orthoses and 46% AT; 48% of children prescribed upper limb orthoses were using them, compared to 98% of children prescribed AT. Greater tone at the wrist was associated with orthotic prescription (OR [95% CI] 39.6 [4.8, 323]).

CONCLUSION

Children with HCP prescribed orthoses and AT are a more severely affected group. AT have higher utility than upper limb orthoses in children with HCP, with orthoses having a high rate of abandonment.

Self-esteem in children and adolescents with mobility impairment: impact on well-being and coping strategies

AIM

The first aim was to investigate dimension-specific and global self-esteem in children and adolescents with mobility impairment and to analyse the relation between self-esteem and demographic data and disability characteristics. The second aim was to identify the impact of five self-esteem dimensions on well-being and coping strategies.

METHODS

A total of 138 children and adolescents aged 7-18 years with mobility impairment took part in a semi-structured interview. Demographic and disability characteristics were recorded and motor function was assessed. Self-esteem was measured by the 'I think I am' inventory. Perceived overall well-being was measured by a nine-grade visual scale, the Snoopy scale, and coping strategies by the Children's Coping Strategies Checklist.

RESULTS

Although a majority estimated a relatively high level of dimension-specific and global self-esteem, several demographic and disability factors for lower self-esteem were identified. Those who estimated their 'physical characteristics' lower used the coping strategy 'distraction' more often. Three out of five dimensions of self-esteem were positively associated with perceived overall well-being: 'physical characteristics', 'psychological well-being' and 'relationships with others'.

CONCLUSION

Awareness of vulnerability factors for lower self-esteem in children and adolescents with mobility impairment offer health care professionals specific opportunities to enhance self-esteem in this group.

Cerebral palsy: medical aspects

Cerebral palsy describes a wide spectrum of motor problems caused by a nonprogressive lesion of the developing brain. It is variably associated with a variety of other developmental and medical problems that present challenges to parents and care providers alike. This article provides an overview of etiology and diagnosis, with a system-based discussion of management.
