Hand-Arm Bimanual Intensive Training in Virtual Reality: A Feasibility Study.

OBJECTIVE: The aim of the study was to evaluate the feasibility of virtual reality (VR) software built using the core concepts of hand-arm bimanual intensive training (HABIT) for improving upper extremity motor function in children with cerebral palsy (CP). METHODS: Eight children with CP participated in a 10-day, 40-hour HABIT program. Half of the time custom VR software, HABIT-VR was used. The children's motor skills were assessed pre- and postintervention with the Assisting Hand Assessment, Box and Blocks Test, and Nine-Hole Peg Test. RESULTS: The children had significant and clinically relevant changes in the Assisting Hand Assessment and Box and Blocks Test; however, Nine-Hole Peg Test scores did not change with intervention. CONCLUSION: These data suggest that combining traditional HABIT strategies with HABIT-VR games improve upper extremity function and gross motor skills but not fine motor skills.

The Effect of Early-Life Seizures on Cognitive and Motor Development: A Case Series.

PURPOSE: This case series documents developmental changes over time and in response to a novel intervention, Sitting Together and Reaching to Play (START-Play), in children with early-life seizures. METHODS: Thirteen children with early-life seizures were included from a subset of participants in the START-Play multisite, randomized controlled trial. Seven received 3 months of twice weekly START-Play intervention; 6 continued with usual care early intervention. Bayley Scales of Infant Development-III (Cognitive Composite), Gross Motor Function Measure-66 Item Set, Assessment of Problem-Solving in Play, and reaching assessments were administered at baseline, 3, 6, and 12 months postbaseline. Change scores are reported at 3 and 12 months postbaseline. RESULTS: Over time, plateau or decline was noted in standardized cognition measures; motor development improved or was stable. Children receiving START-Play showed positive trends in problem-solving (71.4%) and reaching behaviors (57.2%). CONCLUSIONS: Interventions such as START-Play that combine motor and cognitive constructs may benefit children with early-life seizures.

The SIT-PT Trial Protocol: A Dose-Matched Randomized Clinical Trial Comparing 2 Physical Therapist Interventions for Infants and Toddlers With Cerebral Palsy.

OBJECTIVE: Although early intervention for infants at risk for cerebral palsy is routinely recommended, the content of intervention is poorly described, varies widely, and has mixed supporting evidence. The purpose of this study was to compare efficacy of 2 interventions grounded in differing domains of the International Classification of Functioning, Disability and Health on developmental outcomes of infants with or at high risk of cerebral palsy. METHODS: Infants who meet inclusion criteria will be randomized into either Sitting Together and Reaching To Play or Movement, Orientation, Repetition, Exercise Physical Therapy groups. Both groups will receive intervention twice weekly for 3 months and follow-up at 3, 6, 9, and 12 months from baseline. The primary objectives compare changes over time and between groups in sitting, gross motor, and cognitive development. The setting is the infant's home unless the caregiver requests otherwise. One hundred and fifty infants between 8 and 24 months of age will be enrolled in 3 geographically, racially, and ethnically diverse sites: Los Angeles, California; Omaha, Nebraska; and Seattle, Washington. Enrolled infants will demonstrate motor delays, emerging sitting skills, and signs of neurologic impairment. Sitting Together and Reaching To Play targets activities including sitting, reaching, and motor-based problem solving to improve global development. In contrast, Movement, Orientation, Repetition, Exercise Physical Therapy focuses on strengthening and musculoskeletal alignment while encouraging repeated movement practice. Outcome measures include the Gross Motor Function Measure, Bayley Scales of Infant Development-IV, Assessment of Problem Solving in Play, and a Parent Child Interaction assessment. Enrolled children will maintain usual intervention services due to ethical concerns with intervention withdrawal. IMPACT: This will be the first study, to our knowledge, comparing efficacy of early physical therapy with dose-matched interventions and well-defined key principles. The outcomes will inform selection of key principle of intervention in this population.

The Influence of Maternal Cognitions Upon Motor Development in Infants Born Preterm: A Scoping Review.

PURPOSE: This scoping review summarizes the extent, nature, and type of evidence linking broadly defined maternal cognitions to motor outcomes in infants born preterm. Maternal cognitions are beliefs, perceptions, or psychosocial attributes that inform parenting practices. METHODS: Arksey and O'Malley's 5-step method was applied. Thirteen articles between 1980 and November 2019 met inclusion criteria. RESULTS: Two key themes emerged with infants born preterm: (1) quality of the social and physical caregiving environment influence developmental outcomes with implications for motor development; and (2) complex interactions between environmental factors, prematurity-related biomedical risks, and maternal cognitions contribute to eventual motor outcomes. CONCLUSION: Further research is needed to understand how maternal cognitions either scaffold or constrain early motor opportunities for infants born preterm and at risk for motor delays. WHAT THIS ADDS TO THE EVIDENCE: This review summarizes studies that explore potential links between maternal cognitions and motor development in infants born preterm.

Sitting Matters! Differences Between Sitters and Nonsitters at 6 Months' Adjusted Age in Infants At-Risk and Born Preterm.

PURPOSE: Sitting delays in infants born preterm compound cognitive and language deficits. This retrospective study examines differences in prematurity-related risk and compares developmental outcomes between sitters and nonsitters at 6 months' adjusted age. METHODS: A total of 105 graduates of the neonatal intensive care unit met inclusion criteria. Infant demographic and medical risk profiles and 6-month Bayley Scales of Infant Development-3rd edition (BSID-III) cognitive and language scores were retrieved. Infants who sat with hands free greater than 60 seconds were classified as "sitters." RESULTS: Sixty-nine percent of the sample were nonsitters and were born earlier, had lower birth weights, were chronologically older at follow-up, and spent more days with respiratory support. BSID-III scores were significantly higher in sitters but did not differ by gender, multiple birth, head ultrasound results, payment type, or race/ethnicity. CONCLUSION: Sitting abilities at 6 months' adjusted age are associated with prematurity risk factors. Cognitive and language scores differ significantly between sitters and nonsitters.
