RESUMO
Assessing the motor impairments of individuals with neurological disorders holds significant importance in clinical practice. Currently, these clinical assessments are time-intensive and depend on qualitative scales administered by trained healthcare professionals at the clinic. These evaluations provide only coarse snapshots of a person's abilities, failing to track quantitatively the detail and minutiae of recovery over time. To overcome these limitations, we introduce a novel machine learning approach that can be administered anywhere including home. It leverages a spatial-temporal graph convolutional network (STGCN) to extract motion characteristics from pose data obtained from monocular video captured by portable devices like smartphones and tablets. We propose an end-to-end model, achieving an accuracy rate of approximately 76.6% in assessing children with Cerebral Palsy (CP) using the Gross Motor Function Classification System (GMFCS). This represents a 5% improvement in accuracy compared to the current state-of-the-art techniques and demonstrates strong agreement with professional assessments, as indicated by the weighted Cohen's Kappa ( κlw = 0.733 ). In addition, we introduce the use of metric learning through triplet loss and self-supervised training to better handle situations with a limited number of training samples and enable confidence estimation. Setting a confidence threshold at 0.95 , we attain an impressive estimation accuracy of 88% . Notably, our method can be efficiently implemented on a wide range of mobile devices, providing real-time or near real-time results.

Introduction: The coronavirus disease 2019 (COVID-19) pandemic has profoundly affected the utilization of rehabilitation services. Existing evidence investigating this issue at the nationwide level is lacking, and it is uncertain whether the effects of the COVID-19 pandemic on the use of rehabilitation therapy of children and adolescents with cerebral palsy. This study aimed to investigate the impact of COVID-19 on the rehabilitation therapy of children and adolescents with cerebral palsy. Methods: We obtained data from South Korea's Health Insurance Review and Assessment Agency for 2017-2021. By analyzing the claims data, we focused on rehabilitation therapy in individuals with CP under 18 years of age. We categorized these according to therapy type (physical, occupational, or dysphagia), medical facility, hospital visits, and insurance. We calculated the patient counts and average claims per person and compared the average from before to during the COVID-19 pandemic. Results: Over the 5 years, there was a significant decline in the number of patients undergoing rehabilitation therapy (trend p = 0.004), but the average claims per person remained stable (trend p = 0.971). During the COVID-19 pandemic, the average number of claims per person decreased significantly compared to the control period (p = 0.013). Both the physical (p = 0.049) and occupational therapy groups (p = 0.019) showed significant differences in claims. General hospitals and hospitals experienced a decrease in average cases by 2.2 (p < 0.001) and 2.4 (p < 0.001) respectively, while long-term care hospitals increased by 3.1 cases (p < 0.001). Outpatients showed a decline of 2.0 cases (p < 0.001), whereas inpatients showed an increase of 5.9 cases (p < 0.001). Individuals with health insurance decreased by 0.5 cases (p = 0.007), but the decrease of 0.08 cases among medical aid-covered individuals was not statistically significant (p = 0.898). Conclusion: In 2020-2021, the average number of claims per person showed a significant decrease compared to the pre-COVID-19 pandemic period (2017-2019). Depending on the type of treatment, the number of claims for physical and occupational therapy significantly decreased.

OBJECTIVE: Fragility fractures are common among adults with cerebral palsy (CP), but clinical rehabilitation use after fracture and its effect on long-term health outcomes have not been sufficiently studied. The objectives of this study were to identify patterns of the use of physical therapy, occupational therapy, or both in the 6-month postfracture period and the association with 3-year mortality in adults with CP. METHODS: This retrospective cohort study included adults who were ≥18 years old, had CP, and had sustained an incident fragility fracture between January 1, 2014, and December 31, 2016, as identified from a random 20% Medicare fee-for-service dataset. Six-month outpatient physical therapy or occupational therapy use patterns after fracture were identified using group-based trajectory modeling. Cox regression determined the association between physical therapy or occupational therapy use trajectory patterns and mortality from 6 months to 3 years after fracture, adjusting for confounders. Effect modification by key characteristics was tested, including age, sex, and the modified Whitney Comorbidity Index (mWCI), which is a CP-specific comorbidity index that better captures overall medical complexity. RESULTS: Of the 2429 participants included, the majority (73.2%) were characterized as having little to no probability of physical therapy or occupational therapy use, whereas 16.0 and 10.7% were characterized as having early initiation and later initiation, respectively. Compared to the mortality rate for the little to no physical therapy or occupational therapy group, the mortality rates were 26% lower for the early physical therapy or occupational therapy initiation group (hazard ratio [HR] = 0.74; 95% CI = 0.55-1.00) and were 20% lower for the later initiation group (HR = 0.80; 95% CI = 0.57-1.12). There was effect modification by the mWCI. The mortality rate was lower when the early initiation and later initiation groups were compared to the little to no initiation group across all mWCI values examined (median and interquartile range), but the effect was stronger (ie, lower mortality rate) for lower mWCI values for both early initiation and later initiation groups. CONCLUSION: Most adults with CP underutilize outpatient physical therapy or occupational therapy services within 6 months postfracture. Early or later initiation versus little to no physical therapy or occupational therapy use was associated with a lower HR of mortality, although the effect was stronger and statistically significant among those with less medical complexity. IMPACT: Throughout their lives, the use of rehabilitation services in individuals with CP, including physical therapy and occupational therapy, dramatically declines despite the need for continued rehabilitation across their lifespans. This study characterized longitudinal physical therapy or occupational therapy use patterns in the 6 months following a fragility fracture among adults with CP and found that nearly 3 in 4 adults with CP had little to no physical therapy or occupational therapy use during this critical window to optimize postfracture health and function. Further, those who more regularly used physical therapy or occupational therapy services, regardless of the timing of initiation (early vs later), had significantly improved survival up to 3 years after fracture, suggesting the need for greater access to and delivery of clinical rehabilitation services.

Cerebral palsy (CP) is a non-progressive neurologic pathology representing a leading cause of spasticity and concerning gait impairments in children. Robotic-assisted gait training (RAGT) is widely employed to treat this pathology to improve children's gait pattern. Importantly, the effectiveness of the therapy is strictly related to the engagement of the patient in the rehabilitation process, which depends on his/her psychophysiological state. The aim of the study is to evaluate the psychophysiological condition of children with CP during RAGT through infrared thermography (IRT), which was acquired during three sessions in one month. A repeated measure ANOVA was performed (i.e., mean value, standard deviation, and sample entropy) extracted from the temperature time course collected over the nose and corrugator, which are known to be indicative of the psychophysiological state of the individual. Concerning the corrugator, significant differences were found for the sample entropy (F (1.477, 5.907) = 6.888; p = 0.033) and for the mean value (F (1.425, 5.7) = 5.88; p = 0.047). Regarding the nose tip, the sample entropy showed significant differences (F (1.134, 4.536) = 11.5; p = 0.041). The findings from this study suggests that this approach can be used to evaluate in a contactless manner the psychophysiological condition of the children with CP during RAGT, allowing to monitor their engagement to the therapy, increasing the benefits of the treatment.

BACKGROUND The study assessed changes in functional performance of children with cerebral palsy (CP), immediately following treatment and 2 months later, in addition to investigating the relationship between therapy effect and sex, age, or comorbidities. MATERIAL AND METHODS Functional performance of 32 children with spastic diplegia CP, aged 9-16 years, was assessed for: 1) manual function (Box and Block test), motor capacities (Gross Motor Function Measure), sensory capacities (Finger Identification [FI] and Localisation of Tactile Stimuli test [LTC]), and 2) activity and participation, ie, independence in essential and more complex daily activities (Barthel Index; Paediatric Evaluation of Disability Inventory). Measurements were conducted before the start (Month 0), immediately after 6-month rehabilitation program (Month 6), and following a 2-month period with no therapy, ie, 8 months after baseline measurement (Month 8). RESULTS Comparison of Month 0 and Month 6 scores showed significant differences (P<0.001) in all measures. However, Month 8 scores were significantly worse in all the measures, except for sensory capacities assessed using FI and LTC (P<0.001). CONCLUSIONS Functional performance of children with CP was positively affected by 6-month therapy, but 2 months later these effects significantly deteriorated, except for the sensory capacities. This suggests that therapy focusing on functional performance should be included as a permanent component of rehabilitation programs. These findings may be important for clinical practice as they show that therapy of children with CP should be continuous and systematic, and this should be taken into account by those designing therapeutic programs.

BACKGROUND: The purpose of this study was to determine the differences in billable provider charges between single event multilevel surgery (SEMLS) based on comprehensive gait analysis and a staged surgical approach (SSA) without comprehensive gait analysis for the orthopedic treatment of ambulatory children with cerebral palsy (CP). METHODS: The charges associated with nine common orthopedic surgical combinations (both unilateral and bilateral, soft tissue or soft tissue plus bony) for children with CP were determined and compared between SEMLS and SSA. The charges included surgical, anesthesia, operating room, recovery room, hospital stay, physical therapy, and, for SEMLS only, comprehensive computerized gait analysis. RESULTS: Total charges to complete each combination was higher for SSA than for SEMLS. The differential ranged from $10,247 to $75,069 with the percentage difference ranging from 20% to 47%. The mean difference was $43,606 (p = 0.0002). The dollar difference (r = 0.98, p < 0.0001) and percentage difference (r = 0.79, p = 0.01) were both related to the total charge of the SEMLS surgery. SIGNIFICANCE: Financial costs are lower for SEMLS vs. SSA for the treatment of multilevel gait issues in children with CP. The cost of gait analysis is much smaller than the cost differential between SEMLS and SSA. Although some patients who have SEMLS may need additional orthopedic surgery with associated costs, this is also possible for SSA. Therefore, due to the many benefits of SEMLS, which also include more informed treatment decision-making as well as reduced time away from school and work (for caregivers), SEMLS guided by gait analysis is recommended over SSA for the treatment of gait disorders in children with CP.

PURPOSE: This needs assessment survey identifies the priorities of the clinical and research communities involved with the use of instrumented gait analysis (IGA) for a clinical practice guideline on IGA use with children with cerebral palsy (CP). METHODS: Thirteen Likert scale questions asked about the importance of topics related to IGA. Other questions addressed respondents' demographics, experience with IGA, patient populations, and gait laboratory characteristics. Several open-ended questions were included and analyzed. RESULTS: The survey was completed by 43 physical therapists and 53 non-physical therapists involved with IGA. More than 90% rated the following as critically or highly important: reliability and validity of IGA to identify gait pathology (94%); ability to longitudinally track gait pathology (93%); use in planning interventions (93%); use in evaluating outcomes (93%); and definition of IGA (90%). CONCLUSIONS AND RECOMMENDATIONS FOR CLINICAL PRACTICE: This needs assessment survey identified the topic priorities of clinicians and practitioners who use IGA for the management of children with CP. These results will guide the development of a clinical practice guideline on the use of IGA for the management of CP.

PURPOSE: We aimed to translate the Early Clinical Assessment of Balance (ECAB) from English to Japanese and examine the content validity, inter-rater reliability, intra-rater reliability, construct validity, and minimal clinically important difference (MCID) for children with cerebral palsy (CP). METHODS: The ECAB was translated into Japanese per international standards. The study included 106 children with CP and, aged 1.5-12 years. The ECAB, the Gross Motor Function Classification System (GMFCS), and the Gross Motor Function Measure 66 Basal & Ceiling (GMFM-66-B&C) were measured. The content and construct validity were examined based on therapist feedback and correlations between the ECAB and GMFM-66-B&C. The inter-rater reliability and the intra-rater reliability were examined by the intra-class correlation coefficient (ICC). The MCID was calculated by the anchor-based method with the GMFM-66-B&C. RESULTS: High content validity (more than 80% agreement), inter-rater and intra-rater reliability (ICC = 0.99 & 0.99, respectively), and construct validity (r = 0.96) were demonstrated, with MCID values of 7.39, 5.32, and 6.88 observed for the GMFCS I/II, III, and IV/V, respectively. CONCLUSION: The Japanese version of the ECAB is a reliable and valid measure of balance ability in children with CP. Furthermore, the MCID of the ECAB was established, appears to be useful in helping to provide rehabilitation.Implications for RehabilitationThe Japanese version of the Early Clinical Assessment of Balance is easy, safe, and low-cost, and has high reliability and validity for assessing balance ability in children with cerebral palsy.The use of the Japanese version of the Early Clinical Assessment of Balance is beneficial for determining the therapeutic effect, appropriate treatment, and prediction of prognosis regarding balance ability in children with cerebral palsy.The minimal detectable change of the Japanese version of the ECAB suggest that a score exceeding 6 is a true change and the minimal clinically important difference of the Japanese version of the ECAB suggest that the scores exceeding 8, 6, and 7 for the GMFCS I/II, III, and IV/V, respectively, is a clinically useful change.

OBJECTIVES: The aim of this study was to determine the impact of the COVID-19 pandemic on access to rehabilitation therapies and the impact of changes in therapy access on the physical and mental well-being of children with motor impairment and their caregivers. DESIGN: Caregivers of children younger than 18 yrs with childhood-onset motor impairment (primarily cerebral palsy) completed an anonymous survey through the online platform REDCap between May 5 and July 13, 2020. RESULTS: The survey was completed by 102 participants. Before the pandemic, 92 of 102 children (90%) were receiving one or more therapies; at the time surveyed, 55 children (54%) were receiving any therapies (P < 0.001). More than 40% of the sample reported increased child stress, decreased physical activity, and/or decline in mobility/movement. Participants who reported a decrease in number of therapies at the time surveyed more frequently reported lower satisfaction with treatment delivery (P < 0.001), a decline in child's mobility (P = 0.001), and increased caregiver stress (P = 0.004). Five qualitative themes were identified from open-ended question responses related to therapies and well-being. CONCLUSIONS: Access to pediatric rehabilitation therapies was disrupted during COVID-19. Disrupted access may be related to impact on physical and mental health. With the expansion of telehealth, caregiver and child feedback should be incorporated to optimize benefit.

AIM: To determine the predictors of magnitude of change in response to a participation-focused leisure-time physical activity intervention in children with cerebral palsy (CP) using the ParticiPAte CP protocol. METHOD: We included 33 children (16 males, 17 females) aged 8 to 12 years (mean age=10y, SD=1y 6mo) with CP with pre/postintervention data from a wait-list randomized trial. The hypothesized linear predictors of change in primary outcomes (Canadian Occupational Performance Measure [COPM]-performance and COPM-satisfaction, Belief in Goal Self-Competence Scale (BiGSS), and minutes per day moderate-to-vigorous physical activity [MVPA]) were: age; Gross Motor Function Classification System level; comorbid autism spectrum disorder (ASD); Goal Attainment Scaling T score; Problems in Schools Questionnaire; Physical Activity Climate Questionnaire; Motives for Physical Activities Measure-Revised; and stage of behaviour change. Multivariable models were selected using the Bayesian information criterion. RESULTS: Overcoming barriers to participation, age, and comorbid ASD explained 49% of the variance in change in COPM-performance. Being motivated by interest and/or enjoyment and age explained 32% of the variance in change in COPM-satisfaction. Being motivated by physical activity competence or appearance (extrinsic motivation) explained 24% of the variance in change in BiGSS. Parental autonomy supportiveness, overcoming barriers to participation, appearance motivation, and baseline MVPA explained 59% of the variance in change in MVPA. INTERPRETATION: These findings support a behaviour paradigm for conceptualizing physical activity in children with CP. WHAT THIS PAPER ADDS: Children who met their treatment goals showed a greater increase in physical activity participation. Children who were more intrinsically motivated by physical activity at baseline improved more. Being older and having a comorbid diagnosis of autism spectrum disorder were associated with an attenuated effect of the therapy.

BACKGROUND: While COVID-19 outbreak has had adverse psychological effects in children with special needs, the mental state and burden on their caregivers during this pandemic has yet to be reported. AIMS: The objectives of this study were to describe the mental health status and the change in perceived strain among caregivers during the COVID-19 outbreak. METHODS AND PROCEDURES: Two hundred sixty four caregivers completed an online survey that assessed demographics, use and perspective on tele-rehabilitation, homecare therapy, caregiver's strain and mental health. OUTCOMES AND RESULTS: The prevalence of depression, anxiety and stress symptoms were found to be 62.5 %, 20.5 % and 36.4 % respectively. A significant difference in caregiver strain (pâ¯<⯠0.001, effect size = 0.93) was observed during the outbreak compared to levels pre-outbreak (pre-outbreak strain was measured retrospectively). Caregivers not using tele-rehabilitation along with a perception of it being a poor medium for rehabilitation were at greater risks for poor mental health whereas a negative perception on homecare therapy were strongly associated with higher psychological symptoms and strain. CONCLUSIONS AND IMPLICATIONS: This study identified a high prevalence of depression and significant change in strain displayed by caregivers during the COVID-19 outbreak. We identified several factors associated with poor mental health and perceived strain that can be used to help safeguard caregivers.

BACKGROUND: Activities of daily living frequently require children to make rapid decisions and execute desired motor actions while inhibiting unwanted actions. Children with hemiparetic cerebral palsy due to perinatal stroke may have deficits in executive functioning in addition to motor impairments. The objective of this study was to use a robotic object hit and avoid task to assess the ability of children with hemiparetic cerebral palsy to make rapid motor decisions. METHODS: Forty-five children with hemiparetic cerebral palsy due to perinatal stroke and 146 typically developing children (both groups ages 6-19 years) completed a robotic object hit and avoid task using the Kinarm Exoskeleton. Objects of different shapes fell from the top of the screen with increasing speed and frequency. Children were instructed to hit two specific target shapes with either hand, while avoiding six distractor shapes. The number of targets and distractors hit were compared between children with hemiparetic cerebral palsy and typically developing children, accounting for age effects. We also compared performance to a simpler object hit task where there were no distractors. RESULTS: We found that children with hemiparetic cerebral palsy hit a greater proportion of total distractors compared to typically developing children, demonstrating impairments in inhibitory control. Performance for all children improved with age. Children with hemiparetic cerebral palsy hit a greater percentage of targets with each arm on the more complex object hit and avoid task compared to the simpler object hit task, which was not found in typically developing children. CONCLUSIONS: Children with hemiparetic cerebral palsy due to perinatal stroke demonstrated impairments in rapid motor decision making including inhibitory control, which can impede their ability to perform real-world tasks. Therapies that address both motor performance and executive functions are necessary to maximize function in children with hemiparetic cerebral palsy.

Cerebral palsy (CP) describes a group of disorders of movement, posture and balance caused by a non-progressive brain injury in the immature brain. It is the most prevalent cause of chronic motor disability in childhood, and although two thirds of CP children are able to walk, they show gait limitations. In this context, rehabilitation therapy can improve muscle balance and gait. Previous studies showed the importance of gait analysis as part of multidisciplinary tools for effective rehabilitation treatment. However, the high cost and the infrastructure required for the implementation of commercial gait analysis systems as well as the time-consuming preparation procedures, limit the access to this service. A low cost, non-restrictive, portable and of simple operation and installation system was developed based on Kinect v2 sensor. This study aims to validate it for capturing and analysing gait parameters in children with cerebral palsy. Several gait parameters from eleven CP patients with different levels of disability classified as a function of the Gross Motor Function Classification System (GMFCS) from II to III were recorded while they walked on a flat surface. The Kinect-based gait analysis system was compared with video-recording that yielded the same results. These results show the potential of Kinect to analyse gait in frail patient populations unobtrusively and with very low cost. More importantly, regarding to spatial parameters, the Kinect system was useful even for the worst case of GMFCS III that show a large gait variability with abnormal patterns.

In children with cerebral palsy (CP), rigid ventral shell ankle-foot orthoses (vAFOs) are often prescribed to reduce excessive knee flexion in stance and lower the energy cost of walking (ECW). However, how vAFOs affect ECW is a complex issue, as vAFOs may have an impact on lower limb biomechanics, upper body movements, and balance. Besides, the vAFO's biomechanical effect have been shown to be dependent on its stiffness around the ankle joint. We examined whether vAFO stiffness influences trunk movements and gait stability in CP, and whether there is a relationship between these factors and ECW. Fifteen children with spastic CP were prescribed vAFOs. Stiffness was varied into a rigid, stiff and flexible configuration. At baseline (shoes-only) and for each vAFO stiffness configuration, 3D-gait analyses and ECW-tests were performed. From the gait analyses, we derived trunk tilt, lateroflexion, and rotation range of motion (RoM) and the mediolateral and anteroposterior Margins of Stability (MoS) and their variability as measures of gait stability. With the ECW-test we determined the netEC. We found that wearing vAFOs significantly increased trunk lateroflexion (Wald χ2 = 33.7, p < 0.001), rotation RoM (Wald χ2 = 20.5, p < 0.001) and mediolateral gait instability (Wald χ2 = 10.4, p = 0.016). The extent of these effects partly depended on the stiffness of the vAFO. Significant relations between trunk movements, gait stability and ECW were found r = 0.57-0.81, p < 0.05), which indicates that trunk movements and gait stability should be taken into account when prescribing vAFOs to improve gait in children with CP walking with excessive knee flexion.

Individuals with neuromuscular impairment from conditions like cerebral palsy face reduced quality of life due to diminishing mobility and independence. Lower-limb exoskeletons have potential to aid mobility, yet few studies have investigated their use during over-ground walking - an exercise that may contribute to our understanding of potential benefit in free-living settings. The goal of this study was to determine the potential for adaptive plantar-flexor assistance from an untethered ankle exoskeleton to improve over-ground walking economy and speed. Six individuals with cerebral palsy completed three consecutive daily over-ground training sessions to acclimate to, and tune, assistance. During a final assessment visit, metabolic cost, walking speed, and soleus electromyography were collected for baseline, unpowered, low, training-tuned, and high assistance conditions. Compared to each participant's baseline condition, we observed a 3.9 ± 1.9% (p = 0.050) increase in walking speed and a 22.0 ± 4.5% (p = 0.002) reduction in soleus activity with training-tuned assistance; metabolic cost of transport was unchanged (p = 0.130). High assistance resulted in an 8.5 ± 4.0% (p = 0.042) reduction in metabolic cost of transport, a 6.3 ± 2.6% (p = 0.029) increase in walking speed, and a 25.0 ± 4.0% (p < 0.001) reduction in soleus activity. Improvement in exoskeleton-assisted walking economy was related to pre-training baseline walking speed ( [Formula: see text], p = 0.001); the slower and more impaired participants improved the most. Energy cost and preferred walking speed remained generally unchanged for the faster and less impaired participants. These findings demonstrate that powered ankle exoskeletons have the potential to improve mobility-related outcomes for some people with cerebral palsy.

Objective: To assess and evaluate the change in functional skills among children with cerebral palsy (CP) who participated in an intensified habilitation program. Methods: In this prospective longitudinal study, a cohort of 39 preschool children (2-5 years) with cerebral palsy (Gross Motor Function Classification System levels I-V) together with their parents participated in an intensified multidimensional habilitation program for 1 year. Activities strengthening functional skills were among the main interventions. The children were evaluated with the Pediatric Evaluation of Disability Inventory before and after the program period. Results: Only children at GMFCS levels I-II showed improvements in mobility and social function on norm-referenced scales. After the intervention period, these children scored similar to the mean for typically developing children of the same age on the social function domain. Conclusions: Functional skills among preschool children with CP, GMFCS levels I-II, seems strengthened after participation in an intensified habilitation program.

Movement or gait analysis has become a viable assessment tool not only used in sports science or basic biomechanical research, but has also expanded to be a very valuable instrument in clinical diagnostics, monitoring functional recovery and musculoskeletal rehabilitation. In this context, this method has long been an integral part solely in neurological disorders such as cerebral palsy. However, in the meantime the benefits have also become apparent in other medical areas, such as foot surgery, orthopaedic technology, or in patients after lower limb amputation. These procedures proved to better understand, objectify and quantify the individual causes of gait and movement disorders in order to optimize patient-specific therapy. Currently we are able to rely on a multitude of available measurement systems. These can either be used in everyday life for simple monitoring of one's own activity or to complement therapeutic approaches in the clinical and scientific environment. The following review highlights the various fields of movement analysis, including markerless motion capture, marker-based analysis, pedobarography and wearable sensors. Each of these areas presents its own field of application and potential usage as well as the advantages and disadvantages arising in this context. The following article will give an overview of the type of measurement technology used, the respective fields of application, and the selected parameters and their interpretation possibilities for each of the areas mentioned.

Background: Children with cerebral palsy have difficulty to sit, stand, walk, run and jump independently. Therapy is an important factor in improving these aspects, and if applied in early intervention treatments, when the child is growing, it could have many benefits. These therapies require intensive and extended sessions, which in turn demand dedication and effort. New strategies that provide interesting and motivating interventions are often incorporated to improve the participation and performance of the children in the therapies. Therapies using social assistive robots can be alternative and complementary methods to promote the participation and motivation of children with cerebral palsy.Methods: The objective of this work is to validate the effectiveness of a 16-session physical therapy program to improve the participation and fulfillment of therapeutic objectives on an 8 year-old boy with dyskinetic cerebral palsy for motor learning to walk using a social assistive robot. The therapy program was carried out through a methodological proposal that uses SMART objectives (Specific, Measurable, Achievable, Realistic and Timed), Goal-Directed Therapy (GDT) and its evaluation through Goal Attainment Scaling (GAS). Results: A NAO robot was used as a social assistive robot to support a physical therapy for a child with cerebral palsy. In this work, it was observed that the motivation generated by the interaction with the social assistive robot facilitated the persistence in the walking and the fulfillment of the objectives. Conclusion: Using humanoid robots as social assistive robots may benefit therapeutic processes on children with motor disabilities. The methodology developed provides a formal way to achieve objectives in therapeutic processes for children with cerebral palsy.Implications for rehabilitationIt requires researchers to conduct more studies to validate the potential of the use of social robots in therapeutic interventions that promote development in children with motor disabilities, such as cerebral palsy.Promoting the use of new technologies in therapeutic processes such as humanoid robots allows us to create new strategies to know the impact of this technology in the area of rehabilitation.The use of formal methodologies focused on the patient, along with multidisciplinary teams, could increase the possibilities of using social robots to improve cognitive and motor outcomes in children with cerebral palsy.The formulation of SMART objectives and their quantification through the GAS scale can be used as recommendations to improve the formulation of goals in therapeutic interventions for children with cerebral palsy.

OBJECTIVE: To describe the influence of adapted hip-hop dancing on the quality of life (QoL) and biopsychosocial profile of children/adolescents with cerebral palsy (CP). METHODS: Pilot study including 18 children/adolescents with CP and Gross Motor Function Classification System levels I and II. Nine participants took part in an adapted hip-hop dance practice (study group; SG), and nine others served as the control group (CG). All participants were assessed with the Pediatric Outcomes Data Collection Instrument and the Child Behavior Checklist at baseline and after at least three months of dance practice and a public performance (SG) or a similar period without intervention (CG). RESULTS: Improvement in QoL was observed in the SG in the domains of transfer and basic mobility (p = 0.00*), sporting and physical function (p = 0.04*), and global function and symptoms (p = 0.01*). In the SG, there was a reduction in emotional and behavioral problems and an increase in social competence in the biopsychosocial profile. Greater participation in adapted hip-hop dancing was associated with a greater gain in the transfer and basic mobility domains (p = 0.05*) of the Pediatric Outcomes Data Collection Instrument and in the activities (p = 0.05*) and social (p = 0.04*) scales of the Child Behavior Checklist. CONCLUSIONS: Children/adolescents with CP participating in adapted hip-hop dance practice showed improvement in QoL and biopsychosocial profile scores.

RESUMO Descrever a influência da dança hip-hop adaptada na qualidade de vida (QV) e no perfil biopsicossocial de crianças/adolescentes com paralisia cerebral (PC). Método Estudo piloto incluindo 18 crianças/adolescentes com PC, níveis I e II no Sistema de Classificação da Função Motora Grossa. Nove participaram da prática de dança hip-hop adaptada (grupo de estudo; GE) e nove outros compuseram o grupo controle (GC). Os participantes foram avaliados pelo Instrumento Avaliação de Resultados de Reabilitação em Pediatria e pelo Child Behavior Checklist antes e após frequentarem pelo menos três meses de aulas de dança semanais e realizarem uma apresentação ao público (GE) ou período similar sem intervenção (GC). Resultados A melhora da QV foi observada no GE nos domínios: transferência e mobilidade básica (p = 0,00*), função física e esportiva (p = 0,04*), função global e sintomas (p = 0,01*). Na análise do perfil biopsicossocial, houve redução dos problemas emocionais e comportamentais e aumento da competência social no GE. Maior participação na prática esteve associada a maior ganho nos domínios transferência e mobilidade básica (p = 0,05*) do Instrumento Avaliação de Resultados de Reabilitação em Pediatria e nas escalas de atividades (p = 0,05*) e sociais (p = 0,04*) do Child Behavior Checklist. Conclusão A prática de dança hip-hop adaptada proporcionou melhora nos escores de QV e do perfil biopsicossocial de crianças e adolescentes com PC.
