Aims: This study evaluated whether caregiver-provided learning opportunities moderated the effect of START-Play physical therapy intervention on the cognitive skills of young children with neuromotor delays, and whether START-Play impacted caregiver-provided learning opportunities over time. Methods: One hundred and twelve children with neuromot...
Article
Purpose: The purpose of this systematic review was to identify controlled trials evaluating the efficacy of contingency paradigm-based interventions to improve feeding, motor, or cognitive outcomes during the first year of life. Summary of key points: Seventeen studies, including 10 randomized controlled trials, incorporating contingency paradig...
Article
Infants' developing motor skills-including mastery of new postures such as sitting and standing-affect opportunities for learning that facilitate cognitive development. But how infant posture affects caregiver behavior is largely unexplored. Moreover, we know little about effects of posture on learning opportunities in infants with motor delay. Thi...

Importance Cerebral palsy (CP) is the most common childhood physical disability. Early intervention for children younger than 2 years with or at risk of CP is critical. Now that an evidence-based guideline for early accurate diagnosis of CP exists, there is a need to summarize effective, CP-specific early intervention and conduct new trials that ha...
Article
Introduction The purpose of this study was to quantify the relationship between early motor skills, such as sitting, and the development of problem‐solving skills in children with motor delays. Methods Motor (Gross Motor Function Measure) and problem‐solving (Assessment of Problem‐Solving in Play) skills of 134 children 7–16 months adjusted age at...
Article
Full-text available
Therapies for children with cerebral palsy (CP) often fail to address essential components of early rehabilitation: intensity, child initiation, and an embodied approach. Sitting Together And Reaching To Play (START-Play) addresses these issues while incorporating intensive family involvement to maximize therapeutic dosage. While START-Play was dev...
Article
Aim There is a lack of evidence-based tools for measuring problem-solving in young children with motor delays.

Purpose: To evaluate validity, reliability, and sensitivity of the novel Means-End Problem-Solving Assessment Tool (MEPSAT). Methods: Children with typical development and those with motor delay were assessed throughout the first 2 years of life using the MEPSAT. MEPSAT scores were validated against the cognitive and motor subscales of the Bayle...
Article
We propose that the collection of infant experiential and environmental data using smartphone surveys has the potential to fill a gap in foundational and clinical knowledge. To achieve this, these data need to be collected in a systematic way that is translatable globally. We can then begin to understand differences in child development and physica...

Article
Background An early intervention that enhances early development in infants born preterm, called ‘Supporting Play, Exploration and Early Development Intervention’ (SPEEDI) has been shown to be feasible in Virginia, United States, in a pilot study. Infants receive 10 therapy sessions until 3 months' corrected age (CA) (Phase 1[5 hospital sessions] a...
Article
Over 275,000 infants are born very preterm in the US each year. Fifty percent of infants born very preterm will have some degree of neurological dysfunction limiting their ability to keep up with their typically developing peers. Clinical rehabilitation for these high-risk infants has not kept pace with advances in basic science or developmental th...

Article
Aim: To synthesize the existing literature and determine the efficacy of neonatal therapy, starting in the neonatal intensive care unit (NICU), on the motor, cognitive, and behavioral outcomes of infants born preterm. Method: Databases were searched for randomized controlled trials or quasi-randomized controlled trials of direct therapy early in...
Article
A critical factor to move the field of physical therapy forward is the measurement of fidelity during comparisons of interventions. Fidelity translates as "faithfulness"; thus, fidelity of intervention means faithful and correct implementation of the key components of a defined intervention. Fidelity measurement guards against deviations from, or d...
Article
Aims : The American Academy of Pediatrics recommends “parents to incorporate supervised, awake ‘prone play’ in their infant’s routine to support motor development and minimize the risk of plagiocephaly”. The purpose of this feasibility study was to compare usual care to a reward contingency–based intervention, developed to increase prone tolerance...

Purpose: Evaluate the potential of a physical therapy intervention focusing on enhancing cognitive and motor outcomes in a child with severe motor impairments. Design: AB phase design wi...
Article
Knowledge translation is the process by which we take new information that is evidence based and incorporate it into our practice. While we can each incorporate evidence into our practice, the collaboration between a researcher and a clinician can advance the implementation of evidence-based practice. We highlight the use of the Plan-Do-Study-Act c...
Article
Date Presented 04/05/19 For infants with mild motor impairments, parent-provided cognitive opportunities during play continue to increase after mobility is achieved, in contrast to those with severe motor impairment, where cognitive opportunities decrease, as gross motor abilities remain stable. This analysis of two infants demonstrates this differ...

The objectives of this project were to systematically review the impact of mother–infant interaction on the development of infants 12 months or younger and determine factors that mediate this relationship and early development. We systematically reviewed the literature and identified 21 papers which fulfilled inclusion and exclusion criteria. The m...
Article
Background: Associative learning is the ability to discover a relationship between two or more events. We combined principles of learning and technology to develop a paradigm to assess associative learning in prone. Purpose: The purpose of this study was to determine whether 3- to 6-month-old infants can demonstrate: (1) short-term learning of a...
Article
The development of sitting changes how much infants are able to explore objects. Infants who can sit with their arms free are likely to explore their environment more effectively than prop sitters, as their hands are free to explore. We sought to quantify how prop sitters differed in the amount of visual and manual exploration of objects from arms‐...
Article
Parents are their infant's first teachers and play a very important role in early development. Early Intervention strives to enhance infant participation in the family and regulations require the engagement of families in assessment and intervention. Infants born preterm or with motor impairments demonstrate altered social engagements which may inf...
Article
Full-text available
Background: There is limited research examining the efficacy of early physical therapy on infants with neuromotor dysfunction. In addition, most early motor interventions have not been directly linked to learning, despite the clear association between motor activity and cognition during infancy. Objective: The aim of this project is to evaluate...
Article
Full-text available
Background: While therapy services may start in the Neonatal Intensive Care Unit (NICU) there is often a gap in therapy after discharge.

Method: Web of Science, PEDro, PubMed/MEDLINE,...
Article
Infants develop skills through a coupling between their sensory and motor systems. Newborn infants must interpret sensory information and use it to modify movements and organize the postural control system based on the task demands. This paper starts with a brief review of evidence on the use of sensory information in the first months of life, and...
