Personalized Innovative Intervention Pathways to Promote EF in Children With CP

February 26, 2024 updated by: Giuseppina Sgandurra, IRCCS Fondazione Stella Maris

Personalized Innovative Intervention Pathways to Promote Executive Function in Children With Cerebral Palsy

Cerebral palsy (CP) is an umbrella term, covering a group of disorders of movement and posture. It is now accepted that CP represents much more than a disorder of movements considering the frequent association with a broad range of impairments, including cognitive impairments. In general, multiple clinical characteristics that define and determine different functional profiles. Several studies on children with unilateral and bilateral CP have been shown that, despite the overall preserved intellectual functioning, there are specific neuropsychological impairments distinguishing the two forms, including deficits in different Executive Functions (EF) components. Executive Functions (EFs) represent a complex cognitive domain consisting of a set of top-down functions essential for adaptive goal-directed behaviour, allowing to formulate, plan, and organise ideas, cope with challenges and novelties, resist temptations and stay focused. EF represents general domain abilities transversal to several cognitive processes and underling different daily life activities and school learning skills. Empowering EF becomes therefore crucial in children with CP both to strengthen specific functional EF weaknesses and to achieve far transfer effects on other compromised domains, such as motor planning, academic skills,and/or visuospatial processing. To pursue this, the EF training needs to be integrated into the complex and multidisciplinary care context promoting innovative intervention methodologies based on scientific evidence. Recent researches and clinical practice, carried out in our Institute, supports the effectiveness of innovative interventions on EF using new technologies in typical and atypical development, such as Self-adapting web based softwares, Game-based tools or Educational Robotics. Literature suggests these technologies allow to promote timely intervention within a user-friendly context, while respecting the key criteria of evidence-based neuropsychological rehabilitation, both reducing hospitalisation times and supporting interest and motivation for participation. The primary aim of this study is to evaluate the applicability of technological intervention integrated with psychomotor activities to promote EF and then secondary to measure the effect on the functional profile of children with CP, including motor planning, visuo-spatial processing and learning skills, evaluating both short-term (T2) and long-term changes (T3).

Study Overview

Detailed Description

Cerebral Palsy (CP) is an umbrella term, covering a group of permanent disorders of movement and posture development, causing activity limitation. It is now widely accepted that CP motor disorders are frequently associated with a broad range of functional impairments, including cognitive and neuropsychological functions. The presence of epilepsy, premature birth, low birth weight, reduced fetal growth, lesion characteristics and severe gross motor impairment are significant risk factors for cognitive deficit development. Due to the great heterogeneity of the clinical pictures, which depend on the extent, magnitude and timing of the lesion, it is possible to distinguish different forms of CP (International Classification of 2013): spastic forms (approx. 90% of total cases), dyskinetic and ataxic forms. Research indicates a better functional outcome in children with spastic hemiplegia and diplegia compared to those with tetraplegic and ataxic CP, where severe intellectual deficits are more commonly reported, although significant challenges in the standardized assessment of these children are due to more severe motor and oro-motor impairment (Ballester-Plane et al., 2018). A more substantial number of studies have been conducted on children with spastic hemiplegia and diplegia, revealing that, despite overall preserved intellectual functioning, there are specific neuropsychological impairments distinguishing unilateral and bilateral CP. Deficits in different Executive functions (EF) components, playing an important role in behaviour regulation, problem solving, social abilities and the successful completion of everyday activities, are also often reported in literature. One of the reference theoretical models for EFs is the one proposed by Adele Diamond who, starting from Miyake's fractional model, described EFs as made up of three main components (inhibitory control, working memory and cognitive flexibility) which allow the structuring of higher order EFs (reasoning, planning and problem solving). Several studies have identified a close association between EF and other domains considering such processes as transversal to several cognitive and motor functions, also underlying different daily life activities and school learning skills (such as mathematics, reading or writing). The role of specific training on EF becomes crucial in children with CP both to strengthen specific EF weaknesses and to achieve generalised benefits in other compromised domains, such as motor planning, visuospatial processing or academic achievements. To pursue this, the training needs to be integrated into the complex and multidisciplinary care context in which the child with neuromotor disorder is already placed. Recent years have seen the spread of innovative rehabilitation methods, such as Self-adapting web-based software, Game-based systems or Educational Robotics. Literature suggests these technologies have the advantage of intervening in a timely manner, within a home-based context , while following the the key criteria of evidence-based neuropsychological rehabilitation (intensity, self-adaptivity of the exercise and planning fun, enjoyable and motivating activities). In particular, Self-adapting web-based software improving the difficulties of the activities delivered according to the children's performance is used in several neurodevelopmental disorders for the treatment of motor, cognitive, learning and language impairments (e.g. Capodieci et al., 2022).

Game-based tools facilitate meaningful learning, through serious game activities exploiting playful elements and delivering continuous feedback on children's performance. As its video-game nature, the difficulty is adapted to the children' skills and rises progressively according to the learning aims. Educational Robotic (ER) refers to a learning approach requiring children to design, assemble, and program robots through play and hands-on activities. Robot programming may be a tool to increase problem solving skills, cognitive flexibility and inhibition in both typical and atypical development (Di Lieto et al., 2019 and 2020). It is possible to profitably use all of these tools in children with Cerebral Palsy (CP), considering their neuropsychological and motor function impairments.

The aim of this study is to evaluate the applicability and effect of technological intervention integrated with psychomotor activities to promote EF and secondary the impact on academic skills and motor planning in children with CP, evaluating both short-term (T2) and long-term changes (T3). More specific outcomes will be:

  • To verify the feasibility of using new intervention technologies, adopting intensive and self-adaptive methodologies and encouraging interaction and learning between peers.
  • To build three personalised intervention protocols based on the different neuropsychological profiles.
  • To analyse the effect of such intervention on the EF directly targeted
  • To evaluate the generalised effect of the EF intervention on other domains, such as academic skills, visuo-spatial processing and motor planning.

Both short-term (T2) and long-term (T3) changes will be considered.

The attribution to the following treatment paths will not be completely randomised, because based on specific children rehabilitation needs, both considering age and neuropsychological profile:

  • Educational Robotics integrated with psychomotor activities (ERi) in small groups to strengthen EF. The training will take place bi-weekly, for 3 months, for approximately 60 minutes per meeting. For Educational Robotics will be used the Bee-bot, a robot bee-like to program its movement using some directional buttons on the back in order to achieve and reach objectives set in space, therefore allowing to stimulate navigation, visuospatial working memory and planning skills (the activities will be taken from those already used in our previous studies in children with typical development and BES (Di Lieto et al., 2020).
  • Self-adaptive web-based software on EF (RuntheRAN and MemoRAN; https://www.anastasis.it). The training will be conducted at home, for 3 months, for approximately 4/5 days a week for approximately 30/40 minutes per day. An adult (e.g. a family member) will support the child in the treatment and ensure that the exercises are carried out adequately at home. The clinician can monitor and control the intervention progress, also intervening manually on the auto-adaptation, both in online sessions and offline. For the intervention will be used: RuntheRAN (RidiNet, Coopertiva Anastasis), a software that aims to strengthen the prerequisites of reading by requiring the timed and progressively faster naming of colour matrices or black and white figures; MemoRAN (RidiNet, Cooperativa Anastasis), which involves rapid naming exercises of stimuli (figures and colours) presented in matrices, within tasks that require inhibition, cognitive flexibility and updating in working memory.
  • The ELLI's WORLD (https://www.anastasis.it/il-mondo-degli-elli/) integrated with psychomotor activities. The game-based app involves activities in small groups to promote various components of EF (interference control, inhibition, working memory, flexibility). The activities are organised with increasing difficulty, according to the self-adaptive algorithm, and within a narrative context.

The clinical sample will be evaluated at different times during the study period: T1, T2, T3.

The study involves 3 functional assessments: pre-training (T1), after 3 months from T1 assessment for post-training (T2) and after 6 months from T2 assessment for follow-up (T3).

The short-term effect of the treatment will be evaluated by comparing pre- post assessment and the degree of improvement during the training (Percentage of Nonoverlapping Data, https://ktarlow.com/stats/pnd). The long-term effect will be analysed 6 months after the end of the intervention by comparing the performances post intervention with those at the follow-up.

Time Frame: 1-36 months
In the study the investigators will assess the subtests digit span forwards and backwards at the BVN 5-11 (Bisiacchi et al., 2005) and BVN 12-18 (Gugliotta et al., 2009) for assess short-term and working memory, the child is asked to repeat the numbers spoken by the examiner following the same order for the forward condition or reversing the order for the backward condition. The length of the last sequence correctly retrieved is recorded as the span, ranging from 3 to 9 in the forward condition and from 2 to 8 in the backward. Higher span reveals better performance.
1-36 months
changes in score of Go/No-Go and N-back 1 subtest at the teleFE
Time Frame: 1-36 months

TeleFE (Cooperativa Sociale Anastasis) is a web platform for the multidimensional assessment of Executive Functions in developmental ages from 6 to 13 years. In the study the investigators will assess three subtests:

  • In the go/no-go subtest children are asked to press a button when they see only the target stimulus between distracting stimuli that appear on the screen.
  • In subtest n-back 1, children are asked to remember the same item as the previous one within a string of stimuli that appear on the screen.

Both accuracy and speed are scored for each subtest, with percentile score. Higher scores revealed better performances.

1-36 months
changes in score of verbal fluency subtest at the NEPSY-II
Time Frame: 1-36 months
In the study the investigators will assess the Verbal Fluency Subtest at the NEPSY-II (Urgesi et al., 2011), in which the child is asked to generate in one minutes as many words as possible from a given category (animals, food and drinks) or with an initial phoneme (F and S). The test evaluates lexical access and total number of correctly generated word is scored for both the semantic and the phonological condition. The standardised score range is from 1 to 19. Higher scores revealed better performances.
1-36 months

TPV (Hammill, 1994) is a test for the evaluation of visuo-perceptual and visuo-motor integration skills. In the study the investigators will assess the subtests:

  • Copying\ reproduction Subtest: the child sees figures that he must copy
  • Visual\motor speed: the child is asked to draw distinctive designs inside the target figures.
  • Hand-eye coordination: the child is asked to draw some lines inside bands of different widths.
  • Spatial relationships: the child is asked to connect some dots to reproduce the target figure.

From these four subtests, the visual-motor integration score can be calculated and converted into a percentile score. Higher scores revealed better performances.

1-36 months
changes in score of Praxic and Motor Coordination Skills-2nd Edition (APCM-2)
Time Frame: 1-36 months
APCM-2 (Sabbadini, 2015) aims to assess motor and praxis skills in children aged between 2-8 years, with age goup-specific performance tests.APCM-2 enables the early identification of deficits in motor-praxic coordination. The obtained scores facilitate a comprehensive assessment of each case, delineating the functional profile by calculating the deviation from the normative mean and referencing percentile values (5°, 10°, 25°). This approach aids in pinpointing specific functions for each scale, ranging from the most intact to the most impaired.
1-36 months
changes in score of Movement Assessment Battery for Children - Second Edition (Movement ABC-2)
Time Frame: 1-36 months
Movement ABC-2 (Henderson, 2013) evaluates movement difficulties in 3 to 16 years children and adolescents. This assessment battery examines motor difficulties in children and adolescents aged 3 to 16 years. Tasks are categorized by age group and distributed across three sections: manual dexterity, aiming and catching, and balance. Scores are presented in standard scores and percentiles, with interpretation facilitated by a traffic light system. A green light signifies typical motor performance (scores above the 15th percentile), a yellow light indicates a risk for motor impairment (scores between the 5th and 15th percentile), and a red light identifies a significant motor function impairment (scores below the 5th percentile).
1-36 months
changes in score of Synthetic scale for the evaluation of writing in developmental age (BHK test)
Time Frame: 1-36 months
The BHK test (Hamstra-Bletz et al., 2010) evaluates developmental dysgraphia, both the poor quality of the graphic sign (morphological analysis) and the disfluency (speed in the production of graphemes). Both accuracy and speed are evaluated with a z score and a percentile score, respectively. Higher scores reveal better performance.
