The Capacity Profile: a method to classify additional care needs in children with neurodevelopmental disabilities

Mechanically assisted walking training for walking, participation, and quality of life in children with cerebral palsy

BACKGROUND

Cerebral palsy is the most common physical disability in childhood. Mechanically assisted walking training can be provided with or without body weight support to enable children with cerebral palsy to perform repetitive practice of complex gait cycles. It is important to examine the effects of mechanically assisted walking training to identify evidence-based treatments to improve walking performance.

OBJECTIVES

To assess the effects of mechanically assisted walking training compared to control for walking, participation, and quality of life in children with cerebral palsy 3 to 18 years of age.

SEARCH METHODS

In January 2020, we searched CENTRAL, MEDLINE, Embase, six other databases, and two trials registers. We handsearched conference abstracts and checked reference lists of included studies.

SELECTION CRITERIA

Randomized controlled trials (RCTs) or quasi-RCTs, including cross-over trials, comparing any type of mechanically assisted walking training (with or without body weight support) with no walking training or the same dose of overground walking training in children with cerebral palsy (classified as Gross Motor Function Classification System [GMFCS] Levels I to IV) 3 to 18 years of age.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane.

MAIN RESULTS

This review includes 17 studies with 451 participants (GMFCS Levels I to IV; mean age range 4 to 14 years) from outpatient settings. The duration of the intervention period (4 to 12 weeks) ranged widely, as did intensity of training in terms of both length (15 minutes to 40 minutes) and frequency (two to five times a week) of sessions. Six studies were funded by grants, three had no funding support, and eight did not report information on funding. Due to the nature of the intervention, all studies were at high risk of performance bias. Mechanically assisted walking training without body weight support versus no walking training Four studies (100 participants) assessed this comparison. Compared to no walking, mechanically assisted walking training without body weight support increased walking speed (mean difference [MD] 0.05 meter per second [m/s] [change scores], 95% confidence interval [CI] 0.03 to 0.07; 1 study, 10 participants; moderate-quality evidence) as measured by the Biodex Gait Trainer 2™ (Biodex, Shirley, NY, USA) and improved gross motor function (standardized MD [SMD] 1.30 [postintervention scores], 95% CI 0.49 to 2.11; 2 studies, 60 participants; low-quality evidence) postintervention. One study (30 participants) reported no adverse events (low-quality evidence). No study measured participation or quality of life. Mechanically assisted walking training without body weight support versus the same dose of overground walking training Two studies (55 participants) assessed this comparison. Compared to the same dose of overground walking, mechanically assisted walking training without body weight support increased walking speed (MD 0.25 m/s [change or postintervention scores], 95% CI 0.13 to 0.37; 2 studies, 55 participants; moderate-quality evidence) as assessed by the 6-minute walk test or Vicon gait analysis. It also improved gross motor function (MD 11.90% [change scores], 95% CI 2.98 to 20.82; 1 study, 35 participants; moderate-quality evidence) as assessed by the Gross Motor Function Measure (GMFM) and participation (MD 8.20 [change scores], 95% CI 5.69 to 10.71; 1 study, 35 participants; moderate-quality evidence) as assessed by the Pediatric Evaluation of Disability Inventory (scored from 0 to 59), compared to the same dose of overground walking training. No study measured adverse events or quality of life. Mechanically assisted walking training with body weight support versus no walking training Eight studies (210 participants) assessed this comparison. Compared to no walking training, mechanically assisted walking training with body weight support increased walking speed (MD 0.07 m/s [change and postintervention scores], 95% CI 0.06 to 0.08; 7 studies, 161 participants; moderate-quality evidence) as assessed by the 10-meter or 8-meter walk test. There were no differences between groups in gross motor function (MD 1.09% [change and postintervention scores], 95% CI -0.57 to 2.75; 3 studies, 58 participants; low-quality evidence) as assessed by the GMFM; participation (SMD 0.33 [change scores], 95% CI -0.27 to 0.93; 2 studies, 44 participants; low-quality evidence); and quality of life (MD 9.50% [change scores], 95% CI -4.03 to 23.03; 1 study, 26 participants; low-quality evidence) as assessed by the Pediatric Quality of Life Cerebral Palsy Module (scored 0 [bad] to 100 [good]). Three studies (56 participants) reported no adverse events (low-quality evidence). Mechanically assisted walking training with body weight support versus the same dose of overground walking training Three studies (86 participants) assessed this comparison. There were no differences between groups in walking speed (MD -0.02 m/s [change and postintervention scores], 95% CI -0.08 to 0.04; 3 studies, 78 participants; low-quality evidence) as assessed by the 10-meter or 5-minute walk test; gross motor function (MD -0.73% [postintervention scores], 95% CI -14.38 to 12.92; 2 studies, 52 participants; low-quality evidence) as assessed by the GMFM; and participation (MD -4.74 [change scores], 95% CI -11.89 to 2.41; 1 study, 26 participants; moderate-quality evidence) as assessed by the School Function Assessment (scored from 19 to 76). No study measured adverse events or quality of life.

AUTHORS' CONCLUSIONS

Compared with no walking, mechanically assisted walking training probably results in small increases in walking speed (with or without body weight support) and may improve gross motor function (with body weight support). Compared with the same dose of overground walking, mechanically assisted walking training with body weight support may result in little to no difference in walking speed and gross motor function, although two studies found that mechanically assisted walking training without body weight support is probably more effective than the same dose of overground walking training for walking speed and gross motor function. Not many studies reported adverse events, although those that did appeared to show no differences between groups. The results are largely not clinically significant, sample sizes are small, and risk of bias and intensity of intervention vary across studies, making it hard to draw robust conclusions. Mechanically assisted walking training is a means to undertake high-intensity, repetitive, task-specific training and may be useful for children with poor concentration.

The need for additional care in patients with classical galactosaemia

Purpose: Classical galactosaemia is an inborn error of galactose metabolism which may lead to impairments in body functions and accordingly, need for additional care. The primary aim of this study was to establish the type and intensity of this additional care. Materials and methods: Patients with classical galactosaemia aged ≥2 years were evaluated with the Capacity Profile, a standardised method to classify additional care needs according to type and intensity. Based on a semi-structured interview, current impairments in five domains of body functions were determined. The intensity of additional care was assessed (from 0, usual care, to 5, total dependence). Results: Forty-four patients with classical galactosaemia, 18 males and 26 females (median age 15 years, range 2-49 years), were included. There was a wide spectrum of impairments in mental functions. Motor function impairments were present in four patients, and mild speech impairments in eight patients. Additional care for sensory functions was uncommon. All patients needed a diet, which care is scored in the physical health domain. Conclusions: Apart from the diet all patients need, classical galactosaemia leads to the need for additional care mainly in the domains of mental functions and speech and voice functions. Implications for rehabilitation The Capacity Profile is a useful tool to demonstrate additional care needs in classical galactosaemia. In classical galactosaemia additional care is mostly indicated by mental impairments and speech and voice functions. One-fifth of patients have impairment of speech and voice functions at time of the study, and half of all patients had received speech therapy in childhood. Over 70% of patients need additional care/help due to impairment of mental functions, ranging from coaching due to social vulnerability to full day care.

Development and validation of a severity scoring system for Zellweger spectrum disorders

The lack of a validated severity scoring system for individuals with Zellweger spectrum disorders (ZSD) hampers optimal patient care and reliable research. Here, we describe the development of such severity score and its validation in a large, well-characterized cohort of ZSD individuals. We developed a severity scoring system based on the 14 organs that typically can be affected in ZSD. A standardized and validated method was used to classify additional care needs in individuals with neurodevelopmental disabilities (Capacity Profile [CAP]). Thirty ZSD patients of varying ages were scored by the severity score and the CAP. The median score was 9 (range 6-19) with a median scoring age of 16.0 years (range 2-36 years). The ZSD severity score was significantly correlated with all 5 domains of the CAP, most significantly with the sensory domain (r = 0.8971, P = <.0001). No correlation was found between age and severity score. Multiple peroxisomal biochemical parameters were significantly correlated with the severity score. The presently reported severity score for ZSD is a suitable tool to assess phenotypic severity in a ZSD patient at any age. This severity score can be used for objective phenotype descriptions, genotype-phenotype correlation studies, the identification of prognostic features in ZSD patients and for classification and stratification of patients in clinical trials.

Longitudinal neurodevelopmental evolution in children with severe non-progressive encephalopathy

AIM

The aim of this study was to evaluate the longitudinal neurodevelopmental evolution in children with severe non-progressive encephalopathy.

METHODS

Between 1984 and 2005, 17 patients diagnosed with severe non-progressive encephalopathy under the care of the Institute Provvida Madre underwent neurodevelopmental evaluation on an annual basis for at least five consecutive years using the Munich Functional Developmental Diagnostics (MFDD). The severity of each patient's encephalopathy was assessed using the Capacity Profile (CAP). Longitudinal development trends were assessed by means of linear regression analysis, while the degree of discontinuity of the development trajectories was quantified using the Mean Absolute Deviation from Perfect Linear Development (MADPLD). Spearman's rank correlation coefficient and the Mann-Whitney test have been used to investigate the statistical significance of the relationships among the various parameters.

RESULTS

We found that patients with severe non-progressive encephalopathy showed, on average, a linear maturation of 1.5-2.5months per year, irrespective of the neurodevelopmental area considered. Nevertheless, we also discovered that the development trajectories could be discontinuous. Indeed, a given child can show no development sign at all for many years and then suddenly encounter a "development jump", especially in the active language and autonomy areas. However, the long-term development linearity hypothesis seemed to hold true in our study. We also found evidences suggesting that faster development in a given domain could be linked to faster development in other domains, that higher discontinuity in a given area could be associated with higher discontinuity in other areas and that higher degrees of discontinuity could be related to lower developmental evolutions.

CONCLUSIONS

The main findings of this study are important for physicians to form prognoses, counsel effectively and appropriately target therapeutic interventions. In this perspective, there is a strong need to collect long-term repeated follow-up data concerning this group of infants in order to reinforce the findings presented. In fact, these results should be considered as a starting point for further research because they are based on a limited number of patients and more data are needed to confirm the findings.

Functional disability of children with spina bifida: its impact on parents' psychological status and family functioning

OBJECTIVE

To evaluate the impact of functional disability of Turkish children with spina bifida (SB) on parents' psychological status and family functioning.

METHODS

Fifty-four children with SB and parents were included. The Functional Measure for Children (WeeFIM), Beck Depression Inventory (BDI), and Family Assessment Device (FAD) were used.

RESULTS

Mothers' BDI scores were significantly higher than fathers' (p < 0.001). No significant effects of the knowledge of having children with SB before birth and the number of children in families on BDI scores and FAD sub-scores were found (p > 0.05). According to multiple regression analysis; significant correlations with fathers' BDI were problem-solving (p = 0.012) and general functioning (p = 0.037) and with mothers' BDI was roles (p = 0.018). Only childrens age was found to be an influential variable on WeeFIM scores (p < 0.001).

CONCLUSION

Spina bifida healthcare should include psychological support to parents of these children and this support should be independent from disability level of children.

Interrater reliability of the capacity profile in children with neurodevelopmental disabilities

OBJECTIVE

To investigate the interrater reliability of the Capacity Profile (CAP) in children with neurodevelopmental disabilities.

DESIGN

Cross-sectional study.

SETTING

Six rehabilitation centers in the Netherlands.

PARTICIPANTS

Children (N=70) with permanent, nonprogressive neurodevelopmental disabilities.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

The CAP is a method to classify additional care needs of children with nonprogressive neurodevelopmental disabilities in 5 domains of body functions: physical health, motor functions, sensory functions, mental functions, and voice/speech functions. The CAP was scored independently by 2 trained physiatrists during an outpatient visit. Interrater reliability was evaluated using an intraclass correlation coefficient (ICC).

RESULTS

Interrater reliability of the CAP is as follows: physical functions, ICC=.74; motor functions, ICC=.85; sensory functions, ICC=.61; mental functions, ICC=.85; and voice/speech functions, ICC=.79.

CONCLUSIONS

These findings support the interrater reliability of the CAP, when scored during a visit to the rehabilitation center.

Construct validity of the Capacity Profile in adolescents with cerebral palsy

Objective: To establish construct validity of the Capacity Profile, a method to comprehensively classify additional care needs in five domains of body functions (physical health, motor, sensory, mental, voice and speech functions), in adolescents with non-progressive, permanent conditions such as cerebral palsy.

Design: Cross-sectional study.

Subjects: Ninety-four adolescents with cerebral palsy: 60 boys, 34 girls, median age 14.3, range 12—16 years, unilateral (n = 37), bilateral (n = 57), spastic (n = 76), ataxic (n = 4), dyskinetic (n = 5), mixed (dyskinetic and spastic, n =9), Gross Motor Function Classification System: level I (n = 50), level II (n = 6), level III (n = 10), level IV (n = 8), level V (n = 20).

Methods: Associations were calculated between Capacity Profile domains and Vineland Adaptive Behavior Scales (communication, daily activities, social and motor skills) and Gross Motor Function Classification System using Spearman’s rho. Furthermore, we explored the independent contribution of the Capacity Profile domains to activities and participation measured with the Vineland Adaptive Behavior Scales.

Results: All Capacity Profile domains were significantly associated with all domains of the Vineland Adaptive Behavior Scales and the Gross Motor Function Classification System (P<0.05). Multiple regression analysis showed that the Capacity Profile contributed 87% to variance in communication (Capacity Profile-voice 78%, mental 8% and physical 1%), 85% to daily activities (Capacity Profile-mental 75%, motor 8% and voice 2%), 60% to social skills (Capacity Profile-voice 56% and mental 4%), and 91% to motor skills (Capacity Profile-motor 87%, mental 3% and sensory 1%).

Conclusion: These findings support the construct validity of the Capacity Profile in adolescents with cerebral palsy. Construct validity in other medical conditions should be further investigated.

Construct validity of the Capacity Profile in preschool children with cerebral palsy

The Capacity Profile (CAP) classifies additional care needs, subdivided into five domains of body functions (physical health, motor, sensory, mental, and voice/speech) of children with stable conditions. Construct validity of the CAP was established in 72 children (56 males, 16 females) with cerebral palsy (CP); median age 2 years 7 months, range 2 years 6 months to 3 years; 34 unilateral and 37 bilateral spastic-type CP, one dyskinetic-type CP. Gross Motor Function Classification System (GMFCS) classification was 24 in level I, eight in level II, 18 in level III, 14 in level IV, and eight in level V. All CAP domains were significantly associated (p<0.001) with the Functional Skills (rho=-0.42 to -0.85) and Caregiver Assistance scales (rho=-0.42 to -0.82) of the Dutch Paediatric Evaluation of Disability Inventory. The CAP-motor domain and GMFCS were strongly correlated (rho=0.91, p<0.001). Stepwise regression analysis demonstrated that the CAP domains contributed 74% to mobility (CAP-motor 66%, mental 6%, voice 2%); 75% to self-care (CAP-voice 61%, mental 12%, physical 2%); and 70% to social functionality (CAP-mental 68%, voice 2%). CAP demonstrated good construct validity in young children with CP. The independent contribution of CAP domains to daily function underscores the importance of comprehensive assessment with regard to all domains of body functions in heterogeneous conditions like CP.

How well do care providers know the children with developmental disabilities they care for?

AIM

To assess the knowledge from memory of caregivers about the most significant impairments contributing to additional care needs in children with developmental disabilities in therapeutic toddler groups.

METHODS

Children's needs for additional care due to impairments of physical health, motor, sensory, mental and voice and speech functions were separately classified using the capacity profile (CAP). Twenty-three therapists and teachers of toddler groups in two regional centres for paediatric rehabilitation assessed the CAP individually, unprepared and without consulting their notes or the clinical record. These CAP scores (150 CAPs of 44 children) were compared with those based on the clinical record using weighted kappa statistics.

RESULTS

Weighted kappa values for the two sets of CAP scores ranged from 0.22-0.74 (median 0.53), with the lowest scores for the sensory domain (median 0.32, range 0.22-0.52) and the highest scores for the motor domain (median 0.62, range 0.56-0.74).

CONCLUSION

Team members in general had only moderate remembered knowledge of the current impairments determining need of additional care. Remembered knowledge was the poorest for domains not easily observable, such as sensory functions. As this knowledge is essential for optimizing the child's daily environment, improvement of this type of knowledge should be facilitated.
