SENSORS (BASEL, SWITZERLAND) 2024; 24:3787. [PMID: 38931570 PMCID: PMC11207423 DOI: 10.3390/s24123787] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/14/2024] [Revised: 06/06/2024] [Accepted: 06/08/2024] [Indexed: 06/28/2024]
Abstract
Conventional passive ankle foot orthoses (AFOs) have not seen substantial advances or functional improvements for decades, failing to meet the demands of many stakeholders, especially the pediatric population with neurological disorders. Our objective is to develop the first comfortable and unobtrusive powered AFO for children with cerebral palsy (CP), the DE-AFO. CP is the most diagnosed neuromotor disorder in the pediatric population. The standard of care for ankle control dysfunction associated with CP, however, is an unmechanized, bulky, and uncomfortable L-shaped conventional AFO. These passive orthoses constrain the ankle's motion and often cause muscle disuse atrophy, skin damage, and adverse neural adaptations. While powered orthoses could enhance natural ankle motion, their reliance on bulky, noisy, and rigid actuators like DC motors limits their acceptability. Our innovation, the DE-AFO, emerged from insights gathered during customer discovery interviews with 185 stakeholders within the AFO ecosystem as part of the NSF I-Corps program. The DE-AFO is a biomimetic robot that employs artificial muscles made from an electro-active polymer called dielectric elastomers (DEs) to assist ankle movements in the sagittal planes. It incorporates a gait phase detection controller to synchronize the artificial muscles with natural gait cycles, mimicking the function of natural ankle muscles. This device is the first of its kind to utilize lightweight, compact, soft, and silent artificial muscles that contract longitudinally, addressing traditional actuated AFOs' limitations by enhancing the orthosis's natural feel, comfort, and acceptability. In this paper, we outline our design approach and describe the three main components of the DE-AFO: the artificial muscle technology, the finite state machine (the gait phase detection system), and its mechanical structure. To verify the feasibility of our design, we theoretically calculated if DE-AFO can provide the necessary ankle moment assistance for children with CP-aligning with moments observed in typically developing children. To this end, we calculated the ankle moment deficit in a child with CP when compared with the normative moment of seven typically developing children. Our results demonstrated that the DE-AFO can provide meaningful ankle moment assistance, providing up to 69% and 100% of the required assistive force during the pre-swing phase and swing period of gait, respectively.

Digit Health 2024; 10:20552076241259664. [PMID: 38846372 PMCID: PMC11155325 DOI: 10.1177/20552076241259664] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2024] [Accepted: 05/07/2024] [Indexed: 06/09/2024] Open
Abstract
Objective Assessing pain in individuals with neurological conditions like cerebral palsy is challenging due to limited self-reporting and expression abilities. Current methods lack sensitivity and specificity, underlining the need for a reliable evaluation protocol. An automated facial recognition system could revolutionize pain assessment for such patients.The research focuses on two primary goals: developing a dataset of facial pain expressions for individuals with cerebral palsy and creating a deep learning-based automated system for pain assessment tailored to this group. Methods The study trained ten neural networks using three pain image databases and a newly curated CP-PAIN Dataset of 109 images from cerebral palsy patients, classified by experts using the Facial Action Coding System. Results The InceptionV3 model demonstrated promising results, achieving 62.67% accuracy and a 61.12% F1 score on the CP-PAIN dataset. Explainable AI techniques confirmed the consistency of crucial features for pain identification across models. Conclusion The study underscores the potential of deep learning in developing reliable pain detection systems using facial recognition for individuals with communication impairments due to neurological conditions. A more extensive and diverse dataset could further enhance the models' sensitivity to subtle pain expressions in cerebral palsy patients and possibly extend to other complex neurological disorders. This research marks a significant step toward more empathetic and accurate pain management for vulnerable populations.

Abstract
[Purpose] Children with cerebral palsy require more gait energy than healthy children. The association between gait abnormalities and gait efficiency remains unclear. We investigated the association between gait abnormalities, balance, and maximum step length to determine contributors to gait efficiency in children with cerebral palsy. [Participants and Methods] The study included 33 patients with cerebral palsy, who could walk without the use of walking aids. All participants were instructed to walk for 6 min, and the Total Heart Beat Index was calculated as a measure of walking efficiency. The Edinburgh Visual Gait Score was used to assess gait abnormalities. Additionally, the maximum step length was recorded, and all participants performed the Berg Balance Scale. Correlation analysis and stepwise multiple regression analysis were used to confirm the association between the aforementioned parameters and the Total Heart Beat Index. [Results] The Edinburgh Visual Gait Score was correlated with the heel lift during the stance, knee position during the terminal swing of gait as factors associated with the Total Heartbeat Index. The Berg Balance Scale was correlated with turning 360°, standing with feet together. [Conclusion] Our findings emphasize the need for treatment strategies focused on gait abnormalities and balance.

Abstract
Maintaining physical activity is important for children with cerebral palsy (CP). This study examined whether age predicted habitual physical activity (HPA) or cardiorespiratory fitness (CRF) in school-aged children with CP and clarified the relationship between HPA and CRF. We utilized cross-sectional data from 39 children with CP (18 girls and 21 boys; mean age 7.44 years; mean body weight 24.76 kg; mean body mass index 15.97 kg/m2; hemiplegic or diplegic CP). The participants wore an accelerometer (ActiGraph) for five days to measure HPA, physical activity energy expenditure (kcal/kg/d), sedentary physical activity (%SPA), light physical activity, moderate-to-vigorous physical activity (%MVPA), and activity counts (counts/min). Participants underwent cardiopulmonary exercise tests on a treadmill using a modified Naughton protocol. Linear regression and correlation analyses were performed. p-value (two-tailed) < 0.05 was considered statistically significant. Age was positively associated with SPA. MVPA negatively correlated with resting heart rate (HR), and activity counts were negatively correlated with resting HR. In conclusion, our study found strong evidence of a negative association between HPA and age in school-aged children with CP. It highlights the importance of creating and improving recreational opportunities that promote physical activity in all children with CP, regardless of whether they are considered therapeutic.

Abstract
OBJECTIVE This cross-sectional study aimed to assess lower extremity proprioception and investigate its relationship to activity and participation levels in children with unilateral spastic cerebral palsy (USCP). METHODS A total of 22 children with USCP between the ages of 5 and 16 years participated in this study. Lower extremity proprioception was evaluated with a protocol that consisted of verbal and location identification, unilateral and contralateral limb matching, and static and dynamic balance tests performed with the impaired and less impaired lower extremities under eyes-open and eyes-closed conditions. Furthermore, the Functional Independence Measure (WeeFIM) and Pediatric Outcomes Data Collection Instrument (PODCI) were used to evaluate the independence levels in daily living activities and participation levels. RESULTS Children demonstrated proprioceptive loss, as evidenced by an increase in matching errors under the eyes-closed condition compared to the eyes-open condition (p<0.05). Also, the impaired extremity had greater proprioceptive loss than the less impaired extremity (p<0.05). The 5-6-year age group experienced greater proprioceptive deficits than did the 7-11 and 12-16 age groups (p<0.05). Children's lower extremity proprioceptive deficit was moderately associated with their activity and participation levels (p<0.05). CONCLUSIONS Our findings suggest that treatment programs based on comprehensive assessments, including proprioception, may be more effective in these children.

The relation of energy cost of walking with gait deviation, asymmetry, and lower limb muscle co-activation in children with cerebral palsy: a retrospective cross-sectional study. BMC Musculoskelet Disord 2023; 24:111. [PMID: 36759806 PMCID: PMC9909982 DOI: 10.1186/s12891-023-06223-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/07/2022] [Accepted: 06/20/2022] [Indexed: 02/11/2023] Open
Abstract
BACKGROUND Compared to typically developing children, children with cerebral palsy (CP) have increased energy expenditure during walking, limiting activity and participation. Insight into whether the also deviating and more asymmetric gait with increased muscle co-activation contributes to this increased energy expenditure is important for clinical decision making. The aim of this study was to investigate the relation between energy cost of walking with gait deviation, asymmetry, and muscle co-activation in children with CP. METHODS Forty ambulant children with CP, with Gross Motor Function Classification System (GMFCS) level I (N = 35) and II (N = 5), aged between 5-17y, were tested at one or two occasions with 24 weeks in between, resulting in 71 observations. Gross energy cost (J/kg/m) was measured during a 5-min walk test at self-selected speed. From a 3-dimensional gait analyses, kinematic variables and electromyography were extracted to calculate the gait deviation index (GDI) and co-activation index. The relation between energy cost and GDI, GDI asymmetry, and co-activation index of the lower limb muscles was evaluated through mixed model analyses. Height was included to control for growth-related variation. RESULTS Gait deviation and height combined explained about 40% of the variance in gross energy cost. No significant contribution was found for gait asymmetry or co-activation index. CONCLUSIONS This cross-sectional study indicates that increased gait deviation contributes to increased energy cost of walking in children with GMFCS level I and II.

Abstract
This paper serves as an update to the previous RESNA Position on the Application of Power Wheelchairs for Pediatric Users with more current and additional scientific literature. This document contains typical clinical applications and best evidence from the literature supporting the application of power mobility (PM) for young children and to assist practitioners in decision-making and justification. It is RESNA' s position that age, limited vision or cognition, behavioral issues, and the ability to walk or propel a manual wheelchair short distances should not, in and of themselves, be used as discriminatory factors against providing PM for children. RESNA recommends early utilization of PM for children with mobility limitations as medically necessary, to promote integration and psycho-social development, reduce passive dependency, and to enhance participation, function, and independence.

Abstract
Objectives: To describe and critique a systematic multidisciplinary approach to user engagement, and selection and evaluation of sensor technologies for development of a sensor-based Digital Toolkit for assessment of movement in children with cerebral palsy (CP). Methods: A sequential process was employed comprising three steps: Step 1: define user requirements, by identifying domains of interest; Step 2: map domains of interest to potential sensor technologies; and Step 3: evaluate and select appropriate sensors to be incorporated into the Digital Toolkit. The process employed a combination of principles from frameworks based in either healthcare or technology design. Results: A broad range of domains were ranked as important by clinicians, patients and families, and industry users. These directly informed the device selection and evaluation process that resulted in three sensor-based technologies being agreed for inclusion in the Digital Toolkit, for use in a future research study. Conclusion: This report demonstrates a systematic approach to user engagement and device selection and evaluation during the development of a sensor-based solution to a healthcare problem. It also provides a narrative on the benefits of employing a multidisciplinary approach throughout the process. This work uses previous frameworks for evaluating sensor technologies and expands on the methods used for user engagement.

Abstract
AIM To compare skeletal muscle mitochondrial enzyme activity and mitochondrial content between independently ambulatory children with cerebral palsy (CP) and typically developing children. METHOD Gracilis biopsies were obtained from 12 children during surgery (n=6/group, children with CP: one female, five males, mean age 13y 4mo, SD 5y 1mo, 4y 1mo-17y 10mo; typically developing children: three females, three males, mean age 16y 5mo, SD 1y 4mo, 14y 6mo-18y 2mo). Spectrophotometric enzymatic assays were used to evaluate the activity of mitochondrial electron transport chain complexes. Mitochondrial content was evaluated using citrate synthase assay, mitochondrial DNA copy number, and immunoblots for specific respiratory chain proteins. RESULTS Maximal enzyme activity was significantly (50-80%) lower in children with CP versus typically developing children, for complex I (11nmol/min/mg protein, standard error of the mean [SEM] 1.7 vs 20.7nmol/min/mg protein, SEM 4), complex II (6.9nmol/min/mg protein, SEM 1.2 vs 21nmol/min/mg protein, SEM 2.7), complex III (31.9nmol/min/mg protein, SEM 7.4 vs 72.7nmol/min/mg protein, SEM 7.2), and complex I+III (7.4nmol/min/mg protein, SEM 2.5 vs 31.8nmol/min/mg protein, SEM 9.3). Decreased electron transport chain activity was not the result of lower mitochondrial content. INTERPRETATION Skeletal muscle mitochondrial electron transport chain enzymatic activity but not mitochondrial content is reduced in independently ambulatory children with CP. Decreased mitochondrial oxidative capacity might explain reported increased energetics of movement and fatigue in ambulatory children with CP. What this paper adds Skeletal muscle mitochondrial electron transport chain enzymatic activity is reduced in independently ambulatory children with cerebral palsy (CP). Mitochondrial content appears to be similar between children with CP and typically developing children.

Energetics of walking in individuals with cerebral palsy and typical development, across severity and age: A systematic review and meta-analysis. Gait Posture 2021; 90:388-407.

Abstract
BACKGROUND Individuals with cerebral palsy (CP) report physical fatigue as a main cause of limitation, deterioration and eventually cessation of their walking ability. A consequence of higher level of fatigue in individuals with CP leads to a less efficient and long-distance walking ability. RESEARCH QUESTION This systematic review investigates the difference in 1) walking energy expenditure between individuals with CP and age-matched typically developing (TD) individuals; and 2) energetics of walking across Gross Motor Function Classification System (GMFCS) levels and age. METHODS Five electronic databases (PubMed, Web of Science, CINAHL, ScienceDirect and Scopus) were searched using search terms related to CP and energetics of walking. RESULTS Forty-one studies met inclusion criteria. Thirty-one studies compared energy expenditure between CP and age-matched controls. Twelve studies correlated energy expenditure and oxygen cost across GMFCS levels. Three studies investigated the walking efficiency across different ages or over a time period. A significant increase of energy expenditure and oxygen cost was found in individuals with CP compared to TD age-matched individuals, with a strong relationship across GMFCS levels. SIGNIFICANCE Despite significant differences between individuals with CP compared to TD peers, variability in methods and testing protocols may play a confounding role. Analysis suggests oxygen cost being the preferred/unbiased physiological parameter to assess walking efficacy in CP. To date, there is a knowledge gap on age-related changes of walking efficiency across GMFCS levels and wider span of age ranges. Further systematic research looking at longitudinal age-related changes of energetics of walking in this population is warranted.

Abstract
Skeletal muscle contractile proteins require a constant supply of energy to produce force needed for movement. Energy (ATP) is primarily produced by mitochondrial organelles, located within and around muscle fibers, by oxidative phosphorylation that couples electron flux through the electron transport chain to create a proton gradient across the inner mitochondrial membrane that is in turn used by the ATP synthase. Mitochondrial networks increase in size by biogenesis to increase mitochondrial abundance and activity in response to endurance exercise, while their function and content reduce with constant inactivity, such as during muscle atrophy. During healthy aging, there is an overall decline in mitochondrial activity and abundance, increase in mitochondrial DNA mutations, potential increase in oxidative stress, and reduction in overall muscular capacity. Many of these alterations can be attenuated by consistent endurance exercise. Children with cerebral palsy (CP) have significantly increased energetics of movement, reduced endurance capacity, and increased perceived effort. Recent work in leg muscles in ambulatory children with CP show a marked reduction in mitochondrial function. Arm muscles show that mitochondrial protein content and mitochondria DNA copy number are lower, suggesting a reduction in mitochondrial abundance, along with a reduction in markers for mitochondrial biogenesis. Gene expression networks are reduced for glycolytic and mitochondrial pathways and share similarities with gene networks with aging and chronic inactivity. Given the importance of mitochondria for energy production and changes with aging, future work needs to assess changes in mitochondria across the lifespan in people with CP and the effect of exercise on promoting metabolic health.

Stationary cycling is a practical exercise modality in children with cerebral palsy (CP) that lack the strength for upright exercises. However, there is a lack of robust, sensitive metrics that can quantitatively assess the motor control during cycling. The purpose of this brief report was to characterize the differences in motor control of cycling in children with CP and with typical development by developing novel metrics to quantify cycling smoothness and rhythm. Thirty one children with spastic diplegic CP and 10 children with typical development cycled on a stationary cycle. Cycling smoothness was measured by cross-correlating the crank angle with an ideal cycling pattern generated from participant-specific cadence and cycling duration. Cycling rhythmicity was assessed by evaluating the revolution-to-revolution variability in the time required to complete a revolution. Statistically significant differences (p < 0.001) using the Wilcoxon Rank Sum test were found between the two groups for both the metrics. Additionally, decision tree analysis revealed thresholds of smoothness <0.01 and rhythm <0.089-0.115 s for discriminating a less smooth, irregular cycling pattern characteristic of CP from typical cycling. In summary, the objective measures developed in this study indicate significantly less smoothness and rhythm of cycling in children with CP compared to children with typical development, suggestive of altered coordination and poor motor control. Such quantitative assessments of cycling motion in children with CP provide insights into neuromotor deficits that prevent them from cycling at intensities required for aerobic benefits and for participating in cycling related physical activities with their peers.

Evaluation of Individualized Functional Electrical Stimulation-Induced Acute Changes during Walking: A Case Series in Children with Cerebral Palsy. SENSORS 2021; 21:s21134452.

Abstract
Functional electrical stimulation (FES) walking interventions have demonstrated improvements to gait parameters; however, studies were often confined to stimulation of one or two muscle groups. Increased options such as number of muscle groups targeted, timing of stimulation delivery, and level of stimulation are needed to address subject-specific gait deviations. We aimed to demonstrate the feasibility of using a FES system with increased stimulation options during walking in children with cerebral palsy (CP). Three physical therapists designed individualized stimulation programs for six children with CP to target participant-specific gait deviations. Stimulation settings (pulse duration and current) were tuned to each participant. Participants donned our custom FES system that utilized gait phase detection to control stimulation to lower extremity muscle groups and walked on a treadmill at a self-selected speed. Motion capture data were collected during walking with and without the individualized stimulation program. Eight gait metrics and associated timing were compared between walking conditions. The prescribed participant-specific stimulation programs induced significant change towards typical gait in at least one metric for each participant with one iteration of FES-walking. FES systems with increased stimulation options have the potential to allow the physical therapist to better target the individual's gait deviations than a one size fits all device.

Abstract
Activities of daily living (ADL) are key to daily living and adjustment. A number of ADL scales have been developed and validated to examine functional performance in the pediatric population; however, most of these scales are limited to specific groups. The purpose of this research was to test the plausibility of developing and validating a hierarchical versus additive ADL summary scale for children and youth using the interRAI Child Youth Mental Health (ChYMH) assessment system. Data from 8980 typically developing children (mean age 12.02 years) and 655 children with developmental disabilities (mean age 11.9 years) was used to develop ADL summary scales. Patterns among the data were analyzed and, unlike with adult populations, a hierarchical scale did not capture ADL performance and mastery. Two new ADL additive summary scales for children and youth were developed to measure ADL skills within this group.

Abstract
Ageing population is now a global challenge, where physical deterioration is the common feature in elderly people. In addition, the diseases, such as spinal cord injury, stroke, and injury, could cause a partial or total loss of the ability of human locomotion. Thus, assistance is necessary for them to perform safe activities of daily living. Robotic hip exoskeletons are able to support ambulatory functions in elderly people and provide rehabilitation for the patients with gait impairments. They can also augment human performance during normal walking, loaded walking, and manual handling of heavy-duty tasks by providing assistive force/torque. In this article, a systematic review of robotic hip exoskeletons is presented, where biomechanics of the human hip joint, pathological gait pattern, and common approaches to the design of robotic hip exoskeletons are described. Finally, limitations of the available robotic hip exoskeletons and their possible future directions are discussed, which could serve a useful reference for the engineers and researchers to develop robotic hip exoskeletons with practical and plausible applications in geriatric orthopaedics. The translational potential of this article The past decade has witnessed a remarkable progress in research and development of robotic hip exoskeletons. Our aim is to summarize recent developments of robotic hip exoskeletons for the engineers, clinician scientists and rehabilitation personnel to develop efficient robotic hip exoskeletons for practical and plausible applications.

Abstract
Introduction. Cerebral palsy (CP) is caused by an injury to the developing brain, and abnormal gross motor function is a hallmark of CP. Properly structured exercises on land have been reported to be effective in improving functional performance in children with CP while only few have been documented on aquatic therapy. Objective. To investigate the effect of a 10-week aquatic exercise training program on gross motor function in children with spastic CP. Methods. Thirty participants aged 1 to 12 years were randomized into the experimental and control groups. Both groups received manual passive stretching and functional training exercises, depending on their level of motor impairment, either in water (temperature 28°C to 32°C) or on land. Each exercise training session lasted for about 1 hour 40 minutes, twice per week for 10 weeks in both groups. Measurement of gross motor function was done using Gross Motor Function Measure (GMFM-88) at baseline and after 4 weeks, 8 weeks, and 10 weeks of intervention. Both groups were compared for differences in change in gross motor function using Mann-Whitney U test. The level of significance was set at P < .05. Results. Only the experimental group showed significant improvement (P < .05) in all dimensions of gross motor function except for walking, running, and jumping (P = .112). Statistically significant difference (P < .05) was found between both groups for all dimensions of gross motor function after 10 weeks of intervention. Conclusion. Aquatic exercise training program is effective in the functional rehabilitation of children with spastic CP.

Abstract
[Purpose] In children with cerebral palsy, despite increases in muscle strength after
strengthening, improvements in walking efficiency are inconsistent in previous studies.
The purpose of this study was to analyze the relationship between walking efficiency and
muscle strength in children with cerebral palsy. [Participants and Methods] Twenty-six
children with cerebral palsy participated in this study. Isometric muscle strength in the
lower extremities and the Total Heart Beat Index were measured. Participants were divided
into the high and low walking efficiency groups based on the median Total Heart Beat Index
value (2.06 beats/m). [Results] For all participants, all isometric muscle strength values
were significantly correlated with the Total Heart Beat Index. In the high walking
efficiency group, there was no significant correlation. All isometric muscle strength
values in the low walking efficiency group were significantly correlated with the Total
Heart Beat Index, except for that of the hip extensors. [Conclusion] The influence of
muscular strength on walking efficiency in children with cerebral palsy varied.
Significant correlations were observed only for those in the low walking efficiency group.
The walking efficiency level should be confirmed before planning muscle strength training
to improve walking efficiency.

Abstract
INTRODUCTION As the life expectancy has increased in individuals with cerebral palsy, this has led to being able to assess the changes in the bio-psycho-social dimensions of their health. OBJECTIVE The aim of the study is to describe the characteristics of individuals with cerebral palsy and to evaluate their functional situation. METHODS Cross-sectional descriptive study conducted on a sample of 26 individuals between 27 and 65 years old with cerebral palsy. Data was collected during a semi-structured interview. The Cross Motor Function Classification System (GMFCS), the Manual Ability Classification System (MACS), and the Communication Function Classification System (CFCS), were used to evaluate the functional situation. RESULTS The profile of the adult seen in the Cerebral Palsy Association of Burgos, Spain, is male, over 40 years old, single, illiterate, with no professional qualification, lives in a residence, receives social benefit, and with great functional disability. CONCLUSIONS The functional capacity of people with cerebral palsy who are in adult care centres is low. It emphasises the low cultural level and the lack of professional qualification and all of them have a disability that limits their ability to perform daily activities, possibly related to the high mean age.

Abstract
Purpose: To systematically review the evidence about whether activity training on the ground is effective on activity or participation in children with cerebral palsy. Methods: Randomized controlled trials (RCTs) were searched in databases using relevant keywords. RCTs were included with children (≤18 years) with cerebral palsy who received activity training on the ground only or activity training on the ground combined with another type of physiotherapy. Outcome measures classified as measures of activity or participation according to the International Classification of Functioning, Disability, and Health were analyzed. Results: Nine RCTs (257 participants) were included in this review. Individual studies resulted in conflicting results when activity training on the ground was compared to no intervention. Based on meta-analysis, activity training on the ground was not more effective than no intervention (standardized mean difference [SMD]: 0.18; confidence interval [CI]: -1.49 to 1.86) or other therapies (SMD: -0.09; CI: -0.86 to 0.69) (I2 > 75%) on improving activity or participation. Results from a single study demonstrated that activity training on the ground combined with other physiotherapy intervention was not more effective than no intervention (SMD: -0.18 CI: -0.89 to 0.54). Conclusions: The available evidence shows little effect of activity training on the ground on activity or participation in children with cerebral palsy, suggesting that rigorous trials with larger samples and larger "dosage" of activity training on the ground are needed in the future.

Abstract
Background/Purpose Flexed knee gait and stiff knee gait are common coexisting gait disturbances in children with cerebral palsy. We analyzed the effect of medial hamstring transfer and distal rectus transfer around the knee as part of multi-level surgery for this group of patient. Methods Eleven lower limbs of six patients who received double transfer were retrospectively studied. Instrumented gait analysis were carried out before and a minimum of 2 years after operation. Results Comparing the kinematic study before and after the operation, maximum knee extension in stance phase (MKES), total knee swing (TKS) and the time to maximum knee flexion in swing phase (TMKFS) showed statistically significant improvement (p <0.05). Hip extension in swing phase and hip extension power were maintained. The oxygen consumption during walking also decreased after operation (p <0.05). Conclusion Double transfer around the knee can improve both flexed knee gait and stiff knee gait, without causing significant hip extension weakness.

Abstract
[Purpose] To improve walking efficiency could be useful for reducing fatigue and extending possible period of walking in children with cerebral palsy (CP). For this purpose, current study compared conventional parameters of gross motor performance, step length, and cadence in the evaluation of walking efficiency in children with CP. [Subjects and Methods] Thirty-one children with CP (21 boys, 10 girls; mean age, 12.3 ± 2.7 years) participated. Parameters of gross motor performance, including the maximum step length (MSL), maximum side step length, step number, lateral step up number, and single leg standing time, were measured in both dominant and non-dominant sides. Spatio-temporal parameters of walking, including speed, step length, and cadence, were calculated. Total heart beat index (THBI), a parameter of walking efficiency, was also calculated from heartbeats and walking distance in 10 minutes of walking. To analyze the relationships between these parameters and the THBI, the coefficients of determination were calculated using stepwise analysis. [Results] The MSL of the dominant side best accounted for the THBI (R2=0.759). [Conclusion] The MSL of the dominant side was the best explanatory parameter for walking efficiency in children with CP.

Abstract
BACKGROUND Cerebral palsy (CP) is a neurodevelopmental disorder resulting from an injury to the developing brain. It is the most common form of childhood disability with prevalence rates of between 1.5 and 3.8 per 1000 births reported worldwide. The primary impairments associated with CP include reduced muscle strength and reduced cardiorespiratory fitness, resulting in difficulties performing activities such as dressing, walking and negotiating stairs.Exercise is defined as a planned, structured and repetitive activity that aims to improve fitness, and it is a commonly used intervention for people with CP. Aerobic and resistance training may improve activity (i.e. the ability to execute a task) and participation (i.e. involvement in a life situation) through their impact on the primary impairments of CP. However, to date, there has been no comprehensive review of exercise interventions for people with CP. OBJECTIVES To assess the effects of exercise interventions in people with CP, primarily in terms of activity, participation and quality of life. Secondary outcomes assessed body functions and body structures. Comparators of interest were no treatment, usual care or an alternative type of exercise intervention. SEARCH METHODS In June 2016 we searched CENTRAL, MEDLINE, Embase, nine other databases and four trials registers. SELECTION CRITERIA We included randomised controlled trials (RCTs) and quasi-RCTs of children, adolescents and adults with CP. We included studies of aerobic exercise, resistance training, and 'mixed training' (a combination of at least two of aerobic exercise, resistance training and anaerobic training). DATA COLLECTION AND ANALYSIS Two review authors independently screened titles, abstracts and potentially relevant full-text reports for eligibility; extracted all relevant data and conducted 'Risk of bias' and GRADE assessments. MAIN RESULTS We included 29 trials (926 participants); 27 included children and adolescents up to the age of 19 years, three included adolescents and young adults (10 to 22 years), and one included adults over 20 years. Males constituted 53% of the sample. Five trials were conducted in the USA; four in Australia; two in Egypt, Korea, Saudi Arabia, Taiwan, the Netherlands, and the UK; three in Greece; and one apiece in India, Italy, Norway, and South Africa.Twenty-six trials included people with spastic CP only; three trials included children and adolescents with spastic and other types of CP. Twenty-one trials included people who were able to walk with or without assistive devices, four trials also included people who used wheeled mobility devices in most settings, and one trial included people who used wheeled mobility devices only. Three trials did not report the functional ability of participants. Only two trials reported participants' manual ability. Eight studies compared aerobic exercise to usual care, while 15 compared resistance training and 4 compared mixed training to usual care or no treatment. Two trials compared aerobic exercise to resistance training. We judged all trials to be at high risk of bias overall.We found low-quality evidence that aerobic exercise improves gross motor function in the short term (standardised mean difference (SMD) 0.53, 95% confidence interval (CI) 0.02 to 1.04, N = 65, 3 studies) and intermediate term (mean difference (MD) 12.96%, 95% CI 0.52% to 25.40%, N = 12, 1 study). Aerobic exercise does not improve gait speed in the short term (MD 0.09 m/s, 95% CI -0.11 m/s to 0.28 m/s, N = 82, 4 studies, very low-quality evidence) or intermediate term (MD -0.17 m/s, 95% CI -0.59 m/s to 0.24 m/s, N = 12, 1 study, low-quality evidence). No trial assessed participation or quality of life following aerobic exercise.We found low-quality evidence that resistance training does not improve gross motor function (SMD 0.12, 95% CI -0.19 to 0.43, N = 164, 7 studies), gait speed (MD 0.03 m/s, 95% CI -0.02 m/s to 0.07 m/s, N = 185, 8 studies), participation (SMD 0.34, 95% CI -0.01 to 0.70, N = 127, 2 studies) or parent-reported quality of life (MD 12.70, 95% CI -5.63 to 31.03, n = 12, 1 study) in the short term. There is also low-quality evidence that resistance training does not improve gait speed (MD -0.03 m/s, 95% CI -0.17 m/s to 0.11 m/s, N = 84, 3 studies), gross motor function (SMD 0.13, 95% CI -0.30 to 0.55, N = 85, 3 studies) or participation (MD 0.37, 95% CI -6.61 to 7.35, N = 36, 1 study) in the intermediate term.We found low-quality evidence that mixed training does not improve gross motor function (SMD 0.02, 95% CI -0.29 to 0.33, N = 163, 4 studies) or gait speed (MD 0.10 m/s, -0.07 m/s to 0.27 m/s, N = 58, 1 study) but does improve participation (MD 0.40, 95% CI 0.13 to 0.67, N = 65, 1 study) in the short-term.There is no difference between resistance training and aerobic exercise in terms of the effect on gross motor function in the short term (SMD 0.02, 95% CI -0.50 to 0.55, N = 56, 2 studies, low-quality evidence).Thirteen trials did not report adverse events, seven reported no adverse events, and nine reported non-serious adverse events. AUTHORS' CONCLUSIONS The quality of evidence for all conclusions is low to very low. As included trials have small sample sizes, heterogeneity may be underestimated, resulting in considerable uncertainty relating to effect estimates. For children with CP, there is evidence that aerobic exercise may result in a small improvement in gross motor function, though it does not improve gait speed. There is evidence that resistance training does not improve gait speed, gross motor function, participation or quality of life among children with CP.Based on the evidence available, exercise appears to be safe for people with CP; only 55% of trials, however, reported adverse events or stated that they monitored adverse events. There is a need for large, high-quality, well-reported RCTs that assess the effectiveness of exercise in terms of activity and participation, before drawing any firm conclusions on the effectiveness of exercise for people with CP. Research is also required to determine if current exercise guidelines for the general population are effective and feasible for people with CP.

[PMID: 28288332 DOI: 10.1016/j.gaitpost.2017.02.026] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/27/2016] [Revised: 02/10/2017] [Accepted: 02/26/2017] [Indexed: 02/02/2023]
Abstract
AIM This cross-sectional study into children and young adults with cerebral palsy (CP) aimed to assess the association of gross energy cost (EC), net EC and net nondimensional (NN) EC during walking with age and body height, compared to typically developing (TD) peers. METHOD Data was collected in 128 participants with CP (mean age 11y9mo; GMFCS I,n=48; II,n=56; III, n=24) and in 63 TD peers (mean age 12y5mo). Energy cost was assessed by measuring the oxygen consumption during over-ground walking at comfortable speed. Outcome measures derived from the assessment included the gross and net EC, and NN EC. Differences between the groups in the association between gross, net and NN EC with age and body height, were investigated with regression analyses and interaction effects (p<0.05). RESULTS Interaction effects for age and body height by group were not significant, indicating similar associations for gross, net and NN EC with age or body height among groups. The models showed a significant decline for gross, net and NN EC with increasing age per year (respectively -0.201Jkg-1m-1; -0.073Jkg-1m-1; -0.007) and body height per cm (respectively -0.057Jkg-1m-1; -0.021Jkg-1m-1; -0.002). INTERPRETATION Despite higher gross and net EC values for CP compared to TD participants , similar declines in EC outcomes can be expected with growth for participants aged 4-22 years with CP. All energy cost outcomes showed a decline with growth, indicating that correcting for this decline is required when evaluating changes in gross EC, and, to a lesser extent, in net and NN EC in response to treatment or from natural course over time.

Abstract
Cerebral palsy (CP) is a syndrome in which movement and posture disorders are progressive, along with the stationary nature of damage to the central nervous system. Despite the heterogeneity of clinical and functional status, patients with CP are a group of patients at high-risk of the occurrence of diverse pain. The aim of this study was to review literature on the phenomenon of pain in the course of cerebral palsy. An attempt was made to present the characteristics of the phenomenon of pain, and gather tools for its evaluation. A review of Polish and English language literature, in which the issue of pain in the course of cerebral palsy was discussed (in terms of epidemiology, characteristics and evaluation methods). Research papers and reports from the past 15 years included in the databases: PubMed, Medline and websites of Polish medical publishing houses, were analyzed. The works were searched using the key words: cerebral palsy, mental retardation, pain, pain assessment scales. Patients with cerebral palsy – due to their chronic health problems and performed diagnostic-treatment and physiotherapeutic treatments – are at risk of experiencing acute and chronic pain. There is a need to improve knowledge regarding the phenomenon of pain in patients with CP. The optimal course of therapy in this group of patients requires comprehensive and multi-faceted co-operation of doctors, physiotherapists, psychologists and patients as well as their immediate caregivers. Professionals working with patients suffering from CP should be aware of the potential pain causes, possess assessment tools and have the skills and, above all, the desire to use them. cerebral palsy, pain, pain assessment Received: 18.09.2016; accepted: 22nd Jan. 2017

Abstract
BACKGROUND Intramuscular injections of botulinum toxin A (BoNT-A) have been a cornerstone in the treatment of spasticity for the last 20 years. In Norway, the treatment is now offered to two out of three children with spastic cerebral palsy (CP). However, despite its common use, the evidence for its functional effects is limited and inconclusive. The objective of this study is to determine whether BoNT-A makes walking easier in children with CP. We hypothesize that injections with BoNT-A in the calf muscles will reduce energy cost during walking, improve walking capacity, increase habitual physical activity, reduce pain and improve self-perceived performance and satisfaction. METHODS/DESIGN This randomized, double-blinded, placebo-controlled, multicenter trial is conducted in a clinical setting involving three health regions in Norway. Ninety-six children with spastic CP, referred for single-level injections with BoNT-A in the calf muscles, will be invited to participate. Those who are enrolled will be randomized to receive either injections with BoNT-A (Botox®) or 0.9% saline in the calf muscles. Stratification according to age and study center will be made. The allocation ratio will be 1:1. Main inclusion criteria are (1) age 4 - 17.5 years, (2) Gross Motor Function Classification System levels I and II, (3) no BoNT-A injections in the lower limbs during the past 6 months and (4) no orthopedic surgery to the lower limbs during the past 2 years. The outcome measures will be made at baseline and 4, 12 (primary endpoint) and 24 weeks after injections. Primary outcome is change in energy cost during walking. Secondary outcomes are change in walking capacity, change in activity, perceived change in performance and satisfaction in mobility tasks, and pain. The primary analysis will use a linear mixed model to test for difference in change in the outcome measures between the groups. The study is approved by the Regional Ethical Committee and The Norwegian Medicines Agency. Recruitment started in September 2015. DISCUSSION The evaluation of effect is comprehensive and includes objective standardized tests and measures on both impairment and activity level. Results are to be expected by spring 2019. TRIAL REGISTRATION ClinicalTrials.gov, NCT02546999 . Registered on 9 September 2015.

Abstract
The aims of this paper were to investigate the effectiveness of a newly developed wearable hip assist robot, that uses an active assist algorithm to improve gait function, muscle effort, and cardiopulmonary metabolic efficiency in elderly adults. Thirty elderly adults (15 males/ 15 females) participated in thispaper. The experimental protocol consisted of overground gait at comfortable speed under three different conditions: free gait without robot assistance, robot-assisted gait with zero torque (RAG-Z), and full RAG. Under all conditions, muscle effort was analyzed using a 12-channel surface electromyography system. Spatio-temporal data were collected at 120 Hz using a 3-D motion capture system with six infrared cameras. Metabolic cost parameters were collected as oxygen consumption per unit (ml/min/kg) and aerobic energy expenditure (Kcal/min). In the RAG condition, participants demonstrated improved gait function, decreased muscle effort, and reduced metabolic cost. Although the hip assist robot only provides assistance at the hip joint, our results demonstrated a clear reduction in knee and ankle muscle activity in addition to decreased hip flexor and extensor activity. Our findings suggest that this robot has the potential to improve stabilization of the trunk during walking in elderly adults.

Abstract
AIM To describe participation trajectories, and impact of school transitions on those trajectories, of children with cerebral palsy (CP). METHOD This population-based longitudinal study assessed participation in activities outside school of children with CP born in 1994/1995. Eligible children contributed data between two and five occasions over 9 years, and had parents with sufficient English proficiency to complete the measures: the Children's Assessment of Participation and Enjoyment, and the Preferences for Activities of Children. Linear mixed models were used to assess the relationships between participation and age and the impact of transition. RESULTS At study commencement (2006), 233 children with CP born in 1994/1995 were registered in Victoria; 93 (51 males, 42 females; mean age 11y 2mo, age range 10-12y) contributed longitudinal data. Participation diversity and intensity decreased over time for recreational, active physical, and self-improvement activities (p<0.009). Social participation increased over time: diversity, intensity, and frequency (p<0.007). All of the identified slopes were generally small (β≤0.11, 1-point change every 9y) except for recreational diversity scores (β=-0.29). Transition from primary and secondary school had little impact on participation. INTERPRETATION Findings of increased social participation over time are encouraging. Declining participation in other activity types suggests that action is needed to ensure that meaningful recreation and leisure activities are maintained as adolescents with CP transition to adulthood.

Abstract
INTRODUCTION Gait is inefficient in children with cerebral palsy, particularly as they transition to adolescence. Gait inefficiency may be associated with declines in gross motor function and participation among adolescents with cerebral palsy. Resistance training may improve gait efficiency through a number of biomechanical and neural mechanisms. The aim of the Strength Training for Adolescents with cerebral palsy (STAR) trial is to evaluate the effect of resistance training on gait efficiency, activity and participation in adolescents with cerebral palsy. We also aim to determine the biomechanical and neural adaptations that occur following resistance training and evaluate the feasibility and acceptability of such an intervention for adolescents with cerebral palsy. METHODS AND ANALYSIS 60 adolescents (Gross Motor Function Classification System level I-III) will be randomised to a 10-week resistance training group or a usual care control group according to a computer-generated random schedule. The primary outcome is gait efficiency. Secondary outcomes are habitual physical activity, participation, muscle-tendon mechanics and gross motor function. General linear models will be used to evaluate differences in continuous data between the resistance training and usual care groups at 10 and 22 weeks, respectively. A process evaluation will be conducted alongside the intervention. Fidelity of the resistance training programme to trial protocol will be quantified by observations of exercise sessions. Semistructured interviews will be conducted with participants and physiotherapists following the resistance training programme to determine feasibility and acceptability of the programme. ETHICS AND DISSEMINATION This trial has ethical approval from Brunel University London's Department of Clinical Sciences' Research Ethics Committee and the National Research Ethics Service (NRES) Committee London-Surrey Borders. The results of the trial will be submitted for publication in academic journals, presented at conferences and distributed to adolescents, families and healthcare professionals through the media with the assistance of the STAR advisory group. TRIAL REGISTRATION NUMBER ISRCTN90378161; Pre-results.

Abstract
INTRODUCTION Children with cerebral palsy (CP) exhibit increased energy expenditure during movement, but whether this is due in part to decrements in skeletal muscle mitochondrial oxidative capacity is unknown. Accordingly, we compared fiber-type specific succinate dehydrogenase (SDH) activity in children with CP with typically developing (TD) children. METHODS SDH activity and myofiber areas of type 1 and 2A fibers were measured in semitendinosus biopsies of both groups (n = 5/group). RESULTS SDH activity was ∼35% higher in type 1 compared with type 2A fibers, but there were no differences between groups. Average myofiber area was 45% smaller in CP versus TD (P < 0.05), and type 2A fibers were 32% larger than type 1 fibers (P < 0.05) only in TD children. CONCLUSIONS Fiber-type specific SDH activity is similar between TD children and children with CP. This suggests that increased energy expenditure in children with CP is not related to impaired mitochondrial oxidative capacity. Muscle Nerve, 2016 Muscle Nerve 55: 122-124, 2017.

Abstract
Objective: To verify the correlation between visual gait analysis (VGA) by the Edinburgh visual gait score (EVGS) and functional aspects using the Timed Up and Go Test (TUG) and Gross Motor Function Classification System (GMFCS) in individuals with cerebral palsy (CP). Methods: Retrospective cross sectional study of 35 patients with CP. The mean age 12.61 years old, 94.3% were spastic; 34.4% hemiplegic, 54.3% diplegic, 11.4% triplegic; 45.7% were level II GMFCS, 42.9% level I, 5.7% level III and 5.7% level IV. VGA was analyzed by the Edinburgh visual gait score (EVGS), functional mobility was assessed by TUG and functionality through GMFCS. The Spearman correlation was used for statistical analysis. Results: The mean EVGS score was 18.97. The mean TUG was 13.71sec. EVGS showed moderate correlation with TUG (r=0.46, p=0.03) and GMFCS (r=0.45, p=0.00). Conclusion: Worse VGA scores correlate to worse functionality and mobility performance. Due to the observed correlation, it is possible to assert that VGA is a useful tool on evaluation of CP patients. Level of Evidence III, Retrospective Comparative Study.

Abstract
BACKGROUND Efforts to improve the participation and performance of children with cerebral palsy (CP) are often related to the adaptation of environmental conditions to meet their cognitive and motor abilities. However, the influence of affective stimuli within the environment on emotion and performance, and their ability to improve or impede the children's participation has not been investigated in any systematic way although the emerging evidence suggests that it affects the individuals in many levels. OBJECTIVES (1) To measure autonomic responses to affective stimuli during a simulated Meal-Maker task in children with CP in comparison to children who are typically developing, and (2) to examine the interactions between autonomic functions, subjective reports of stress, and task performance among children with and without CP. METHODS Fifteen children with CP and 19 typically developing peers (6 to 12 years) participated. After completing behavioral questionnaires (e.g., State and Trait Anxiety Inventories), children prepared meals within a camera tracking virtual Meal-Maker environment. Either a negative, positive, or neutral visual stimulus was displayed, selected from the International Affective Picture System. Children also passively viewed the same pictures while rating their valence and arousal levels. Heart rate (HR) and skin conductance were recorded synchronously with stimulus onset. RESULTS Significant differences in autonomic functions were found between groups, i.e., a higher "low frequency" to "high frequency" (LF:HF) ratio in the children with CP during the meals associated with a negative stimulus (p=0.011). Only children with CP had significant positive correlations between trait anxiety and LF:HF ratio during virtual meal-making associated with positive (p=0.049) and negative stimuli (p=0.003) but not during neutral stimuli. For children with CP the amplitude of skin conductance response during passive picture viewing was significantly higher for negative than for positive stimuli (p=0.017) but there were no significant changes in autonomic responses during virtual Meal-Maker task. Significant correlations between trait anxiety, autonomic activity during the calm state and Meal-Maker performance outcomes were found only for children with CP. CONCLUSIONS In general, the Meal-Maker virtual environment was shown to be a feasible platform for the investigation of the effect of emotionally loaded stimuli on the balance of autonomic functions in children with and without CP. Anxiety level appears to play a significant role in children with CP and should be considered as a potentially important factor during clinical evaluation and intervention. Further studies are needed to develop additional measurements of emotional responses and to refine the types of affective interference.

Abstract
PURPOSE The purpose of this study was to determine the absolute reliability and responsiveness of the Timed Up and Go (TUG) test, as measured using minimal detectable change (MDC) and minimal clinical important difference (MCID) values. METHODS Prospective observational study of children aged 3 to 10 years with cerebral palsy (CP) in Gross Motor Function Classification System levels I-III who completed the TUG test. Minimal detectable change estimates were calculated using baseline data. MCID estimates for each Gross Motor Function Classification System (GMFCS) level were calculated using distribution- and anchor-based methods. RESULTS Minimal detectable change values ranged from 1.40 to 8.74 seconds and MCID estimates ranged from 0.22 to 5.31 seconds. CONCLUSIONS The TUG test is a reliable and responsive measure of balance and mobility for children with CP between 3 and 10 years of age in GMFCS levels I-III. Study results support improved use of the TUG test in clinical and research settings by providing reliability values and estimates of meaningful change.

Abstract
BACKGROUND Reduced participation in physical activity and increased time spent in sedentary behavior are associated with overweight, chronic disease, and disability. In order to optimize recommendations and interventions to increase physical activity and reduce sedentary behavior in children with cerebral palsy (CP), knowledge of their physical activity and sedentary behavior is needed. OBJECTIVES The aim of this study was to describe light, moderate, and vigorous physical activity and sedentary behavior in preadolescent children with and without CP and compare physical activity and sedentary behavior between the 2 groups. DESIGN This was a cross-sectional study of 33 children, aged 6 to 10 years, with CP (Gross Motor Function Classification System [GMFCS] levels I-III) and 33 age- and sex-matched children with typical development. METHODS Physical activity was measured using the RT3 accelerometer over 7 days. RESULTS Children with CP spent more time in sedentary behavior and accumulated less total activity, moderate activity, vigorous activity, and sustained bouts of moderate-to-vigorous activity (MVPA). They also accumulated a fewer number of bouts of MVPA and vigorous activity, despite spending a similar amount of time in each bout. LIMITATIONS The small number of children in GMFCS levels II and III did not allow for adjustment for GMFCS level when comparing physical activity between children with and without CP. CONCLUSIONS Preadolescent children with CP spent less time in moderate and vigorous activity and more time in sedentary behavior than children with typical development. Children with CP also accumulated less continuous MVPA and vigorous activity as a result of achieving fewer sustained bouts of MVPA and vigorous activity throughout the day.

Abstract
PURPOSE To examine if individualised resistance training increases the daily physical activity of adolescents and young adults with bilateral spastic cerebral palsy (CP). METHOD Young people with bilateral spastic CP were randomly assigned to intervention or to usual care. The intervention group completed an individualised lower limb progressive resistance training programme twice a week for 12 weeks in community gymnasiums. The primary outcome was daily physical activity (number of steps, and time sitting and lying). Secondary outcomes included muscle strength measured with a one-repetition maximum (1RM) leg press and reverse leg press. Outcomes were measured at baseline, 12 weeks and 24 weeks. RESULTS From the 36 participants with complete data at 12 weeks, there were no between-group differences for any measure of daily physical activity. There was a likely increase in leg press strength in favour of the intervention group (mean difference 11.8 kg; 95% CI -1.4 to 25.0). No significant adverse events occurred during training. CONCLUSIONS A short-term resistance training programme that may increase leg muscle strength was not effective in increasing daily physical activity. Other strategies are needed to address the low-daily physical activity levels of young people with bilateral spastic CP. IMPLICATIONS FOR REHABILITATION Progressive resistance training may increase muscle strength but does not lead to increases in daily physical activity of young people with bilateral spastic cerebral palsy (CP) and mild to moderate walking disabilities. Other strategies apart from or in addition to resistance training are needed to address the low daily physical activity levels of young people with bilateral spastic CP and mild to moderate walking disabilities.

Abstract
PURPOSE To assess healthcare use and family perception of family-centred care in children and young adults with severe cerebral palsy (CP) within a geographical region of the UK. METHOD Young people (4-27years) with severe forms of CP; Gross Motor Function Classification System levels IV and V, were recruited via an established case register. Data were collected in the participant's home using a standardised background proforma and validated questionnaires. The Measure of Processes of Care was used to assess the family's perception of family-centred care. RESULTS One-hundred and twenty-three children, young people and their families/guardians participated. Results showed high accessing of specialist services in childhood with a considerable decrease in young adults. Use of generalist services remained relatively constant. The reported use of formal respite services and support groups/youth clubs was relatively poor. Family-centred care was poor in the area of "providing general information" (2.8 ± 1.73) but more moderate in the areas of "providing specific information about the young person" (4.2 ± 1.94), "enabling and partnership" (4.2 ± 1.9), "co-ordinated and comprehensive care" (4.3 ± 1.95) and "respectful and supportive care" (4.7 ± 1.75). CONCLUSIONS The accessing of specialist services and respite care notably decreases amongst adolescents with severe forms of CP and the perception of family-centred care amongst families was fair at best. In particular, the results highlight the need for families to be provided with more general information and advice. Implications for Rehabilitation In a quest to enhance the rehabilitation process in young people with severe forms of cerebral palsy: Commissioners and service providers need to a adopt a more rationalised, needs led approach to service provision across the lifespan of people with severe forms of cerebral palsy, to include an effective and efficient transitional period. Habilitation specialists working with young adults need to continue to recognise the importance of family-centred care in managing this complex and chronic condition. Professionals working within the healthcare system must provide better communication and improve their dissemination of information to the families of children and young people with complex needs.

Abstract
The Berg balance scale (BBS) and the paediatric balance scale (PBS) are reliable tools for measuring balance ability. However, reports of BBS and PBS scores in adolescent cerebral palsy have been limited. The objectives of this study were to investigate functional balance capacities, as tested with the BBS and PBS in adolescents with cerebral palsy, to compare the total PBS and BBS scores between Gross Motor Function Classification System-Expanded and Revised (GMFCS-E&R) levels and to compare the static balance PBS and BBS scores within each GMFCS-E&R level. Fifty-eight school-aged adolescents with cerebral palsy between the ages of 12 and 18 years with GMFCS-E&R levels of I to IV were recruited. The Kruskal-Wallis test was utilized to compare the median scores for the PBS and BBS between the different GMFCS-E&R levels. Wilcoxon signed-rank tests were performed to examine the differences in the static balance scores between the PBS and the BBS within the same GMFCS-E&R levels. The results reveal that there were differences in the BBS and PBS scores among the four GMFCS-E&R levels. A significant difference was found between the BBS and PBS scores only among the patients with cerebral palsy and level III GMFCS-E&R. The BBS and PBS are valid and reliable tools for clinical examination and for distinguishing between levels of functional balance in adolescents with cerebral palsy.

Abstract
Multilevel surgery is commonly performed to improve walking in children with cerebral palsy (CP). Classical gait analysis (kinetics, kinematics) demonstrated positive outcomes after this intervention, however it doesn't give global indication about gait's features. The assessment of energy cost and mechanical work of locomotion can provide an overall description of walking functionality. Therefore, we propose to describe the effects of multilevel surgery in children with CP, considering energetics, mechanical work, kinetic and kinematic of walking. We measured external, internal, total work, energy cost, recovery, efficiency, kinetic and kinematic of walking in 10 children with CP (4 girls, 6 boys; 13 years ± 2) before and 1 year after multilevel surgery. Kinetic and kinematic results are partially comparable to previous findings, energy cost of walking is significantly reduced (p < 0.05); external, internal, total work, recovery, efficiency are not significantly different (p = 0.129; p = 0.147; p = 0.795; p = 0.119; p = 0.21). The improvement of the walking's energy consumption is not accompanied by a corresponding improvement of mechanical work. Therefore it is conceivable that the improvement of walking economy depend on a reduced effort of the muscle to maintain the posture, rather then to an improvement of the mechanism of energy recovery typical of human locomotion.

Abstract
AIM Adolescents and young adults with cerebral palsy (CP) show reduced motor function and gait efficiency, and lower levels of habitual physical activity (HPA), than adolescents with typical development and children with CP. This study examined activity duration and patterns in this population in the Middle East through long-term monitoring of a large sample using accelerometers. METHOD Adolescents and young adults with bilateral CP at Gross Motor Function Classification System (GMFCS) levels II, III, and IV, were monitored in their habitual environment for four consecutive days with ActivPAL3 monitors. Time spent in sedentary, standing, and walking activities, and frequency of walking steps and transitions, were analysed for each GMFCS level. RESULTS Measurements were made on 222 participants (132 males, 90 females; mean age 16 y 9 mo SD 2y, range 13 y 4 mo-22 y). The Mann-Whitney U test demonstrated significant differences (p<0.05) between GMFCS levels, showing reduced walking and standing activity and increased sedentary duration at higher GMFCS levels (p<0.001), except for increased standing time between GMFCS levels II and III (p=0.07). Participants in educational facilities exhibited less sedentary behaviour than those who were homebound (p<0.05). INTERPRETATION These descriptions of duration and frequency of active and sedentary behaviours may serve as a basis for recommendations to minimize inactivity in this population. Adolescents and young adults with CP in the Middle East demonstrate similar patterns of HPA to their peers in other regions.

Abstract
The goal of the International Classification of Functioning is to standardize the classification of health and function of children around the world. To facilitate the application of this classification, International Classification of Functioning-based tools like the "Core Sets" are being developed. We conducted an international survey of professional experts to identify the most relevant areas of functioning in children with cerebral palsy. The questionnaire covered each component of the classification. In total, 193 professionals completed the survey (response rate 78%). Overall, 9706 answers were linked to the classification (pediatric version) by 2 professionals. From the experts' perspective, movement-related areas and social participation are the most relevant areas of functioning. Experts suggest a more comprehensive profile of functioning in particular in areas of personal capacity and social participation. The results of this survey will inform the development of the International Classification of Functioning Core Sets for children with cerebral palsy.

Abstract
The energy cost (EC) of walking is different for typically developing (TD) and children with cerebral palsy (CP). The associated factors of EC are not fully understood in children with CP. We assessed the relationship between EC and age, body surface area (BSA), and gross motor function measure (GMFM). We retrospectively examined data collected between 2003 and 2011 on 276 children aged 4-18 years who were classified as Gross Motor Function Classification System level I, n=79; II, n=123; and III, n=74. Energy cost was assessed while children walked 6-8 min at a comfortable, self-selected speed using their typical walking aids and/or orthoses as part of a clinical gait analysis. During the test, participants wore a breath-by-breath portable gas analysis system, measuring oxygen consumption. To calculate EC (J/kg/m), oxygen consumption was converted to J/kg/min and divided by walking speed. Data were analyzed using linear regression model. Energy cost correlated inversely with age (β=-0.16, R2=0.02, P=0.01), BSA (β=-3.35, R2=0.11, P<0.0001), and GMFM (β=-0.12, R2=0.42, P<0.0001). In the multiple linear regression model, GMFM was the most potent correlate of EC, BSA explained another 10% of the variance (R2=0.53), and age was a marginally significant correlate of EC (P=0.08). In summary, in children with CP in our study, EC decreased as GMFM and BSA increased, and GMFM was the most potent correlate of EC.

Abstract
The International Classification of Functioning children and youth version (ICF-CY) provides a universal framework for defining and classifying functioning and disability in children worldwide. To facilitate the application of the ICF in practice, ICF based-tools like the "ICF Core Sets" are being developed. In the context of the development of the ICF-CY Core Sets for children with Cerebral Palsy (CP), the aims of this study were as follows: to identify and compare the content of outcome measures used in studies of children with CP using the ICF-CY coding system; and to describe the most frequently addressed areas of functioning in those studies. We searched multiple databases likely to capture studies involving children with CP from January 1998 to March 2012. We included all English language articles that studied children aged 2-18 years and described an interventional or observational study. Constructs of the outcome measures identified in studies were linked to the ICF-CY by two trained professionals. We found 231 articles that described 238 outcome measures. The outcome measures contained 2193 concepts that were linked to the ICF-CY and covered 161 independent ICF-CY categories. Out of the 161 categories, 53 (33.5%) were related to body functions, 75 (46%) were related to activities/participation, 26 (16.1%) were related to environmental factors, and 7 (4.3%) were related to body structures. This systematic review provides information about content of measures that may guide researchers and clinicians in their selection of an outcome measure for use in a study and/or clinical practice with children with CP.

Abstract
We aimed to identify predictors for the changes of various developmental outcomes in preschool children with cerebral palsy (CP). Participants were 78 children (49 boys, 29 girls) with CP (mean age: 3 years, 8 months; SD: 1 year, 7 months; range: 1 year to 5 years, 6 months). We examined eight potential predictors: age, sex, CP subtype, Gross Motor Function Classification System (GMFCS) level, selective motor control, Modified Ashworth Scale, and the spinal alignment (SA) and range of motion subscales of the Spinal Alignment and Range of Motion Measure (SAROMM). Developmental outcomes for cognition, language, self-help, and social and motor functions were measured at baseline and a 6-month follow-up with the Comprehensive Developmental Inventory for Infants and Toddlers. Regression model showed GMFCS level was a negative predictor for change of language (adjusted r(2)=0.30, p<.001), motor function (adjusted r(2)=0.26, p<.001), social function (adjusted r(2)=0.07, p=0.014), and self-help (adjusted r(2)=0.26, p<.001). Age was a negative predictor for change of cognition (adjusted r(2)=0.21, p<.001) and language functions (adjusted r(2)=0.26, p<.001). SAROMM-SA was a negative predictor for cognitive change (adjusted r(2)=0.30, p<.001). The GMFCS levels and age are robust negative predictors for change of most developmental domains in these children.

Abstract
Mechanical efficiency (ME) during stair-climbing measures ambulation ability. This study investigated the relationship between ME and age, anthropometric, functional walking, and balance parameters in 52 adolescents with cerebral palsy (CP), age 13.5-23.3 yrs, who participated in an intervention study to improve walking. Measurements included ME, 6-min and 10-m walk tests and the Berg balance scale (BBS). Walk test measures correlated significantly with ME, as expected, as did BBS (r=0.68) and age (r=0.51). The multiple correlation coefficient with both age and BBS increased to 0.80. The measurements were divided into two groups of low (<40, n=19) and high (>40, n=33) BBS scores. Repeating regression analyses, demonstrated that in the low BBS group ME was significantly related to BBS, but not age, in contrast to opposite results in the high BBS group. Regressions were calculated for each of the 14 items of the BBS with ME. For the whole group, 12 items correlated significantly, but only three in the high BBS group (one leg standing, reach while standing and tandem standing). In the low BBS group 10 of the items correlated significantly, with the former three ranking near the top. Balance is an important component of ambulation in children with CP. Mobility in those scoring>40 is related to age, but in those more deficient in balance (<40) mobility is more closely associated with balance than age. Effective therapy to improve walking in younger children might incorporate more balance-focused exercises, similar to those related to BBS items strongly associated with ME.

Abstract
PURPOSE The aim of the study was to describe the lived bodily experience of cerebral palsy (CP). METHOD This was a descriptive phenomenological inquiry. Ten participants were interviewed about their bodily experiences of living with CP. Interviews were semi-structured around pain and fatigue. Inductive thematic analysis was used to identify themes. RESULTS The bodily experience of CP centered on issues of fatigue and pain as a feeling of muscle soreness. An overwhelming amount of the discussion on fatigue emphasized the fatigue that occurs with walking and prolonged activity. Self-awareness of the individuals' own bodies and adapting activity to continue to participate in various aspects of their lives emerged as the most important theme. Some participants used strategies to manage their pain or fatigue; other participants were not yet fully aware of how to recognize signs of fatigue and/or how to adapt their activities. CONCLUSIONS Self-awareness appears to be an important process to be fostered by service providers and parents. Specifically, encouraging youth with CP to be aware of their own bodies and the effects (positive and negative) of activity on pain and fatigue should be incorporated into transition programs as the individual becomes responsible for his or her own health care needs. Implications for Rehabilitation Fatigue is a major concern for some youth and young adults with cerebral palsy. Adolescents and young adults with cerebral palsy use a variety of techniques (including adapting or restricting activity and building in rest breaks) to manage fatigue. The process of self-awareness should be fostered by health care professionals leading up to and during transition from pediatric to adult care. Clinical conversations should explore the role of exercise, adaptive equipment, rest and other strategies for dealing with fatigue with a focus on understanding each client's needs individually.

Abstract
The aim of this study was to quantitatively assess the stability and harmony of gait in children with cerebral palsy. Seventeen children with spastic hemiplegia due to cerebral palsy (5.0±2.3 years old) who were able to walk autonomously and seventeen age-matched children with typical development (5.7±2.5 years old, p=0.391) performed a 10-m walking test with a wearable device fixed to their lower trunk and included a triaxial accelerometer and three gyroscopes. Three parameters related to gait stability and three related to gait harmony were computed; all of these yielded significant differences between children with cerebral palsy and those with typical development (p<0.020 for all the computed parameters). In the latter group of children, trunk accelerations were found to be negatively correlated with age (partial correlation controlled for walking speed: R(p)<-0.58, p>0.020). Conversely, in children with cerebral palsy, the upper body accelerations were proportionally correlated with their gait speed (R=0.548, p=0.023 in the antero-posterior direction) but not with their age (p>0.05). This finding can be related both to difficulties in managing the higher upper body accelerations involved in rapid walking and to compensation strategies.
