Parents' experiences with a home-based upper limb training program using a video coaching approach for infants and toddlers with unilateral cerebral palsy: a qualitative interview study.

BACKGROUND: Although early home-based upper limb training programs are promising, in-depth understanding of parents' experiences with these programs is still limited. We developed an early home-based upper limb training program for infants and toddlers (8-36 months) with or at risk of unilateral cerebral palsy using video coaching for parents. The aim of this qualitative study was to evaluate parents' experiences with the home-based training program using a video coaching approach in order to optimize implementation strategies. METHODS: We held semi-structured interviews with parents of 13 children with unilateral cerebral palsy, who participated in our program in the period from 2014 - 2017. On average, parents had delivered two training periods of the program at the time of the interviews. Interviews were analyzed using inductive thematic content analysis. RESULTS: We identified three overarching interacting themes that shaped the experiences of parents with the program: 1) Parental learning comprising the subthemes parents' training competencies and the facilitative and reinforcing role of video coaching, 2) Parental load comprising the subthemes flexibility of the program, supportive network, competing demands, and child's mood and functional capacities, and 3) Parental perseverance comprising the subthemes beliefs and expectancies and seeing child's functional improvements. CONCLUSIONS: For successful implementation of an early home-based upper limb training program using video coaching, support in delivering home-training from a therapist or from others within parents' social network, is needed to relieve parental load. Seeing functional improvements of their child on the videos increased parents' motivation to continue with the training. Positively phrased feedback from an occupational therapist stimulated parents' perseverance and training competency.

Neglect-like characteristics of developmental disregard in children with cerebral palsy revealed by event related potentials.

BACKGROUND: Children with unilateral Cerebral Palsy (CP) often show diminished awareness of the remaining capacity of their affected upper limb. This phenomenon is known as Developmental Disregard (DD). DD has been explained by operant conditioning. Alternatively, DD can be described as a developmental delay resulting from a lack of use of the affected hand during crucial developmental periods. We hypothesize that this delay is associated with a general delay in executive functions (EF) related to motor behavior, also known as motor EFs. METHODS: Twenty-four children with unilateral CP participated in this cross-sectional study, twelve of them diagnosed with DD. To test motor EFs, a modified go/nogo task was presented in which cues followed by go- or nogo-stimuli appeared at either the left or right side of a screen. Children had to press a button with the hand corresponding to the side of stimulus presentation. Apart from response accuracy, Event-Related Potentials (ERPs) extracted from the ongoing EEG were used to register covert cognitive processes. ERP N1, P2, N2, and P3 components elicited by cue-, go-, and nogo-stimuli were further analyzed to differentiate between different covert cognitive processes. RESULTS: Children with DD made more errors. With respect to the ERPs, the P3 component to go-stimuli was enhanced in children with DD. This enhancement was related to age, such that younger children with DD showed stronger enhancements. In addition, in DD the N1 component to cue- and go-stimuli was decreased. CONCLUSIONS: The behavioral results show that children with DD experience difficulties when performing the task. The finding of an enhanced P3 component to go-stimuli suggests that these difficulties are due to increased mental effort preceding movement. As age in DD mediated this enhancement, it seems that this increased mental effort is related to a developmental delay. The additional finding of a decreased N1 component in DD furthermore suggests a general diminished visuo-spatial attention. This effect reveals that DD might be a neuropsychological phenomenon similar to post-stroke neglect syndrome that does not resolve during development. These findings suggest that therapies aimed at reducing neglect could be a promising addition to existing therapies for DD.

A pilot study of the Video Observations Aarts and Aarts (VOAA): a new software program to measure motor behaviour in children with cerebral palsy.

A new computer software program to score video observations, Video Observations Aarts and Aarts (VOAA) was developed to evaluate paediatric occupational therapy interventions. The VOAA is an observation tool that assesses the frequency, duration and quality of arm/hand use in children, in particular those with cerebral palsy. Reliability studies show that the first module, designed to evaluate a forced-use programme, has an excellent content validity index (0.93) and good intra- and inter-observer reliability (Cohen's kappas ranging from 0.62 to 0.85 for the three activities tested). With the built-in statistical package, paediatric occupational therapy departments can conduct therapeutic evaluations with children with impairments in the upper extremities. Further research is recommended to apply the VOAA in clinical studies in paediatric occupational therapy.
