The Effect of Video-Based Action Observation Training and Live Action Observation Training on Motor Function, Activity Participation, and Secondary Outcome Measures in Children With Spastic Diparetic Cerebral Palsy: A Randomized Controlled Study

BACKGROUND

This study aimed to investigate the effects of Video-Based Action Observation Training and Live Action Observation Training on motor function, activity participation, and secondary outcome measures in children with spastic diparetic cerebral palsy (CP).

MATERIALS AND METHODS

Thirty-nine children with spastic diparetic cerebral palsy, aged 5-14 years, with Gross Motor Function Classification System I-III, were distributed in equal numbers to any of the Video-Based Action Observation Training (conventional physiotherapy + Video-Based Action Observation Training), Live Action Observation Training (conventional physiotherapy + Live Action Observation Training), and control (conventional physiotherapy) groups through stratified randomization. For 8 weeks, action observation training groups received 20 minutes of conventional physiotherapy followed by 20 minutes of action observation training, and the control group received 40 minutes of conventional physiotherapy. Primary outcome measures were Gross Motor Function Measurement and Child and Adolescent Scale of Participation, secondary outcome measures were Pediatric Berg Balance Scale, timed-up-and-go test, five times sit-to-stand test (FTSST), Gillette Functional Assessment Questionnaire (GFAQ), and 1-minute walk test (1MWT).

RESULTS

Improvements were observed in all other evaluation parameters of the groups except Gross Motor Function Measurement-lying and rolling (P = .066) in the Live Action Observation Training Group, and lying and rolling (P = .317) and crawling and kneeling (P = .063) motor subtests and Gillette Functional Assessment Questionnaire-walking scale (P = .513) in the control group. Comparisons of the increases in all other measurements between the groups, except for the dimensions of Gross Motor Function Measurement-lying and rolling (P = .172), were statistically significant (P < .05) and this difference was in favor of action observation training.

CONCLUSION

It was found that 2 different AOTs applied in addition to conventional physiotherapy in children with spastic diparetic cerebral palsy were more effective on all outcomes than was conventional physiotherapy alone.

Effects of a 12-Week Mixed-Method Physical Exercise Program on Physical Fitness, Stress, Anxiety, and Quality of Life in Adolescents with Cerebral Palsy: A Case Series Study

BACKGROUND/OBJECTIVES

Although the health benefits related to physical exercise for adolescents with cerebral palsy (CP) have been recognized, studies indicate that individuals with CP at school age are less involved in physical activities than their typical peers and are twice as likely to engage in sedentary behaviors. Therefore, our study aims to investigate the effects of a physical exercise program on physical fitness, stress, anxiety, and quality-of-life variables.

METHODS

A total of 15 teenagers with ambulatory CP (n = 8 boys, n = 7 girls, between 12 and 18 years old; M = 14.35; SD = 1.76) completed a 12-week program based on a mixed-method approach with face-to-face and live online activities. The outcome measures were physical fitness, stress, anxiety, and quality of life.

RESULTS

The 12-week exercise program resulted in gains in muscular strength, flexibility, and aerobic endurance tests, characterized by an increase in average walking speed and average VO2 max. There was also a significant change in the perception of emotional states of depression, anxiety, and stress reported by the participants.

CONCLUSIONS

The program proved to be effective in physical fitness tests and perception of emotional states. Given the positive effects produced by the program, its design appears to meet the demands of adolescents with cerebral palsy.

The Methodological Quality of Studies on Physical Exercise in Adolescents with Cerebral Palsy: A Scoping Review of Systematic Reviews and Meta-Analyses

INTRODUCTION

Systematic reviews and meta-analyses point to the benefits of physical exercise for adolescents with cerebral palsy, improving physical conditioning, muscle strength, balance, and walking speed. However, given the high number of reviews that include randomized and non-randomized studies, it is increasingly necessary to assess the methodological quality of these reviews. This scoping review investigated the methodological quality of systematic reviews and meta-analyses on the effects of physical exercise in adolescents with cerebral palsy to elucidate the methodological limitations of the research and the priorities to be observed in future research.

METHOD

The electronic search used PubMed, Web of Science, and Cochrane. Studies published between 2016 and 2023 were selected. The terms used were "cerebral palsy" combined with "physical fitness", "exercise", and "physical activity".

RESULTS

A total of 219 original reviews were selected. Of these, 19 reviews were included for data analysis. AMSTAR2 was used to assess the methodological quality of the reviews. Three reviews presented high methodological quality (15.78%) and three had moderate methodological quality (15.78%). The remaining reviews had low or critically low methodological quality, according to AMSTAR2.

INTERPRETATION

This study evidenced that systematic reviews have variable methodological quality and that new studies are still needed.

Care Pathways in Rehabilitation for Children and Adolescents with Cerebral Palsy: Distinctiveness of the Adaptation to the Italian Context

BACKGROUND

In 2020, a multiprofessional panel was set up in collaboration with the Italian FightTheStroke Foundation family association to produce evidence-based recommendations for the management and neuromotor rehabilitation of persons with cerebral palsy aged 2-18 years to implement in clinical practice in Italy.

METHODS

The recommendations of these care pathways were developed according to the American Academy for Cerebral Palsy and Developmental Medicine guidelines for Care Pathways Development and the Grading of Recommendations Assessment Development and Evaluation working group for adoption, adaptation, or de novo development of recommendations from high-quality guidelines (GRADE-ADOLOPMENT).

RESULTS

Four strong positive recommendations were developed regarding comprehensive management, and twenty-four addressed neuromotor treatment.

CONCLUSIONS

A holistic, individualized approach was affirmed in terms of both multidimensional patient profile and interdisciplinary management in a network with the school where children and adolescents are integrated. It was defined that all motor rehabilitation approaches must be individually tailored considering age and developmentally appropriate activities as interventions and goals, in light of the reference curves addressing prognosis for Gross Motor Function and Manual Ability Classification Systems. Intervention must be structured with adaptations of the task and/or of the context (objects and environment) based on the analysis of the child's skills to support motivation and avoid frustration.

Cognitive approaches in the rehabilitation of upper limbs function in children with cerebral palsy: a systematic review and meta-analysis

INTRODUCTION

Cerebral palsy (CP) is the predominant cause of children disability. It is characterized by motor, sensory, and postural deficits due to a non-progressive injury to the developing central nervous system. In recent years, new rehabilitation techniques targeting the central representations of motor patterns have been introduced: the most used are action observation therapy (AOT), motor imagery (MI), and mirror therapy (MT). Aim of this study is to assess the effectiveness of these cognitive strategies on the recovery of upper limb motor functions in children with CP.

EVIDENCE ACQUISITION

This study was designed as a systematic review and meta-analysis, registered in PROSPERO (CRD42023403794). For the report and methodological definitions of this study, the recommendations of the PRISMA protocol and the Cochrane collaboration, were followed. A total of 3 electronic databases (PubMed, Scopus, and Web of Science) were searched for relevant Randomized Control Trials (RCT) using the combinations of terms "cerebral palsy" AND "action observation" OR "motor imagery" OR "mirror therapy" OR "cognitive therapy." A meta-analysis was carried out to compare cognitive and conventional approaches and combine direct and indirect effects. A random-effects meta-analysis model was used to derive pooled effect estimates.

EVIDENCE SYNTHESIS

Out of 328 records, 12 RCTs were analyzed in this systematic review published from 2012 to 2022, and included 375 children, of whom 195 received cognitive therapies, and 180 underwent conventional rehabilitation. AOT was the most investigated (RCTs N.=7), and showed significant results in the recovery of upper limb motor functions, albeit the meta-analysis demonstrated a non-significant difference in Melbourne Unilateral Upper limb Scale (MUUL) (95% CI: -7.34, 12); in Assisting Hand Assessment (AHA) (95% CI: -4.84, 10.74), and in AbilHand-Kids Questionnaire (95% CI: -1.12, 1.45). Five RCTs investigated MT showing significant improvements in grip and dexterity; none used MI as intervention therapy.

CONCLUSIONS

Cognitive therapies provided with encouraging results in the recovery of upper limb motor functions, although not a clinical effect in bimanual or unimanual performance; they could represent a valid therapeutic solution integrated to conventional rehabilitation in the treatment of upper limb motor impairment in children with CP.

Evidence-based management and motor rehabilitation of cerebral palsy children and adolescents: a systematic review

Background

Evidence regarding the management of several aspects of cerebral palsy improved in recent years. Still, discrepancies are reported in clinical practice. Italian professionals and stakeholders expressed the need of setting up updated, evidenced-based, shared statements, to address clinical practice in cerebral palsy rehabilitation. The objective of the present study was to provide an updated overview of the state of knowledge, regarding the management and motor rehabilitation of children and young people with cerebral palsy, as the framework to develop evidence-based recommendations on this topic.

Methods

Guidelines and systematic reviews were searched, relative to evidence-based management and motor treatment, aimed at improving gross motor and manual function and activities, in subjects with cerebral palsy, aged 2-18 years. A systematic search according to the Patients Intervention Control Outcome framework was executed on multiple sites. Independent evaluators provided selection and quality assessment of the studies and extraction of data.

Results

Four guidelines, 43 systematic reviews, and three primary studies were included. Agreement among guidelines was reported relative to the general requirements of management and motor treatment. Considering the subject's multidimensional profile, age and developmentally appropriate activities were recommended to set individual goals and interventions. Only a few approaches were supported by high-level evidence (i.e., bimanual therapy and constraint-induced movement therapy to enhance manual performance). Several task-specific active approaches, to improve gross motor function and gait, were reported (mobility and gait training, cycling, backward gait, and treadmill), based on low-level evidence. Increasing daily physical activity and countering sedentary behavior were advised. Based on the available evidence, non-invasive brain stimulation, virtual reality, action-observation therapy, hydrotherapy, and hippotherapy might be complementary to task or goal-oriented physical therapy programs.

Conclusion

A multiple-disciplinary family-centered evidence-based management is recommended. All motor rehabilitation approaches to minors affected by cerebral palsy must share the following fundamental characteristics: engaging active involvement of the subject, individualized, age and developmentally appropriate, goal-directed, skill-based, and preferably intensive and time-limited, but suitable for the needs and preferences of the child or young person and their family, and feasible considering the implications for themselves and possible contextual limitations.

Effectiveness of a Telecare Physical Therapy Program in Improving Functionality in Children and Adolescents with Cerebral Palsy: A Cases Study

Cerebral palsy (CP) is the most common physical disability in childhood and results in motor impairment that is often associated with other disorders. The aim of this study was to assess whether a telecare intervention consisting of Action Observation Therapy with a family-center approach produces improvements in functionality in children and adolescents with CP. Seven girls with CP ages between 6 and 17 participated in this case series study that lasted 12 weeks: 6 weeks of telecare program with a total of six sessions; and a follow-up period of 6 weeks. The outcome variables were Gross Motor Function (Spanish version of the Gross Motor Function Measure), balance (Spanish version of the Pediatric Balance Scale), walking endurance (6-min walk test) and walking speed (10-m walk test). The variables were measured before starting the study, after 6 weeks of intervention and after the 6-week follow-up period. Results showed statistically significant improvements in gross motor function (p = 0.02) after the intervention. After the follow-up period, gross motor function remained statistically significant (p = 0.02), as well as balance (p = 0.04) and walking endurance (p = 0.02). These results show that a telecare program has been beneficial in improving functionality with enhancements in gross motor function, balance and endurance in children and adolescents with CP that will facilitate participation.

Towards functional improvement of motor disorders associated with cerebral palsy

Cerebral palsy is a lifelong neurodevelopmental condition arising from non-progressive disorders occurring in the fetal or infant brain. Cerebral palsy has long been categorised into discrete motor types based on the predominance of spasticity, dyskinesia, or ataxia. However, these motor disorders, muscle weakness, hypotonia, and impaired selective movements should also be discriminated across the range of presentations and along the lifespan. Although cerebral palsy is permanent, function changes across the lifespan, indicating the importance of interventions to improve outcomes in motor disorders associated with the condition. Mounting evidence exists for the inclusion of several interventions, including active surveillance, adapted physical activity, and nutrition, to prevent secondary and tertiary complications. Avenues for future research include the development of evidence-based recommendations, low-cost and high-quality alternatives to existing therapies to ensure universal access, standardised cerebral palsy registers to harmonise epidemiological and clinical information, improved adult screening and check-up programmes to facilitate positive lived experiences, and phase 3 trials for new interventions.

Can a pathological model improve the abilities of the paretic hand in hemiplegic children? The PAM-AOT study protocol of a randomised controlled trial

Introduction

Action Observation Treatment (AOT) is an innovative therapeutic approach consisting in the observation of actions followed by subsequent repetition. In children with unilateral cerebral palsy (UCP), it improves upper limb function in daily activities. The standard paradigm of AOT requires the observation of healthy models; however, it has been demonstrated that the mirror neuron system of children with UCP is more activated by observation of pathological models, showing a similar motor repertoire, than by the healthy model, suggesting that AOT based on pathological models is superior to the standard paradigm of AOT in the functional rehabilitation of the affected upper limb of children with UCP.

Methods and analysis

This protocol describes an active two-arm randomised controlled evaluator-blinded trial. Twenty-six children with UCP will participate in 3 weeks of intensive AOT: the experimental group will observe a pathological model, while the control group will observe a typically developed model. The primary outcome is the spontaneous use of the paretic hand, measured with the Assisting Hand Assessment. Secondary outcome measures are the Melbourne Assessment of Unilateral Upper Limb Function, the ABILHAND-Kids and the Activities Scale for Kids-performance. Assessments will be performed at baseline (T0), at the end of intensive AOT (T1), at 8–12 weeks (T2) and at 24–28 weeks (T3) after the end of intensive AOT.

Ethics and dissemination

The trial was approved by the Area Vasta Emilia Nord Ethics Committee (AVEN prot. n. 133117, 29 November 2018), and it was prospectively registered on ClinicalTrials.gov. The results will be submitted for publication to a peer-reviewed journal, discussed with parents of children participating in the trial and disseminated at suitable conferences.

Early intervention evidence for infants with or at risk for cerebral palsy: an overview of systematic reviews

AIM

To perform an overview of systematic reviews and more recent randomized controlled trials (RCTs) on early motor interventions in infants aged 0 to 3 years with or at risk of cerebral palsy to inform current clinical and research efforts and provide a benchmark to assess future interventions ideally initiated within the first 6 months.

METHOD

Standardized searches of the PubMed, Embase, Scopus, and Web of Science databases were conducted for systematic reviews (2009-2020) and RCTs (2015-2020).

RESULTS

From 840 unique records, 31 full texts were reviewed, yielding three systematic reviews encompassing 46 studies, 16 with comparison groups, and six additional RCTs that met the criteria. Two enrichment- and activity-based approaches had medium effect sizes on motor development, only one with low risk of bias; two others had large task-specific effect sizes but some bias concerns; and three enriched environment studies with some bias concerns had medium effect sizes on cognitive development. Most had small or no effect sizes, bias concerns, and uncertain diagnostic determinations.

INTERPRETATION

Data synthesis revealed limited data quantity and quality, and suggest, although not yet confirmed, greater benefit from early versus later intervention. Research efforts with greater early diagnostic precision and earlier intervention are accelerating, which may transform future outcomes and practices. What this paper adds For over 50% of trials within the reviews, the intervention was compared to standard care with only two showing efficacy. Similar to results in older children, constraint-induced movement therapy (CIMT) emerged as efficacious with high effect sizes. CIMT was not superior to similarly intense bimanual training or occupational therapy. Goals-Activity-Motor Enrichment intervention initiated before 5 months of age was superior to equally intense standard care. Several other enriched environment strategies promoted cognitive and/or motor development.

The role of mirror mechanism in the recovery, maintenance, and acquisition of motor abilities

While it is well documented that the motor system is more than a mere implementer of motor actions, the possible applications of its cognitive side are still under-exploited, often remaining as poorly organized evidence. Here, we will collect evidence showing the value of action observation treatment (AOT) in the recovery of impaired motor abilities for a vast number of clinical conditions, spanning from traumatological patients to brain injuries and neurodegenerative diseases. Alongside, we will discuss the use of AOT in the maintenance of appropriate motor behavior in subjects at risk for events with dramatic physical consequences, like fall prevention in elderly people or injury prevention in sports. Finally, we will report that AOT can help to tune existing motor competencies in fields requiring precise motor control. We will connect all these diverse dots into the neurophysiological scenario offered by decades of research on the human mirror mechanism, discussing the potentialities for individualization. Empowered by modern technologies, AOT can impact individuals' safety and quality of life across the whole lifespan.
