Rationale: Dosing of pediatric physical therapy intervention is a current topic of high interest in the field, and researchers are starting to investigate the feasibility of different approaches for providing early, intense interventions. Although these approaches are laudable and strongly theoretically based there is a fundamental gap: it is currently unknown what amount and type of leg movement experience is necessary and sufficient to have a positive effect on the development of infant neuromotor control.
Intervention: The intervention promotes movement experience from 3 months to sitting onset in infants at risk for developmental delay (AR). The goal of the intervention is to increase amount and type of infant leg movement experience above 1200 movements per hour of awake time with 1/3 single and 2/3 bilateral leg movements.
Objective: The first aim is to determine the effectiveness of the intervention to increase leg movement and neurodevelopment in infants AR versus a cohort of infants from the same population who received standard care. The second aim is to determine the association of amount of leg movement experience and motor development rate.
Study population: This study will include 12 infants AR from 3 months of corrected age until sitting onset or 9 months corrected age, whichever occurs first.
Study methodology: Single-arm, prospective intervention study.
Study outcomes: The primary outcome will be leg movement rate at 9 months of corrected age and the secondary outcome will be neurodevelopmental outcomes (good or poor).
Follow-up: Families will be contacted every 4 months from 9-24 months of corrected age for updates on their child's medical and developmental status.
Statistics and plans for analysis. The investigators hypothesize that infants in this study (all of whom will receive the intervention) will have higher leg movement rates and lower risk of poor neuromotor outcomes at 9 months corrected age than an existing observation-only sample of infants from the same population who received usual care. The investigators will explore whether the relationship between amount of movement and rate of motor development is linear or non-linear.

Experimental: Movement intervention
The intervention promotes movement experience from 3 months to sitting onset in infants at risk for developmental delay (AR). The goal of the intervention is to increase amount and type of infant leg movement experience above 1200 movements per hour of awake time with 1/3 single and 2/3 bilateral leg movements.
Behavioral: Movement Intervention
At each visit, the caregiver will be reminded of the infant's movement rate and proportion of unilateral and bilateral movements from the last visit. The research team will help the caregiver to determine possible ways to achieve the goal of 1200 movements per hour of awake time, with 1/3 single leg movements and 2/3 bilateral leg movements. Strategies to increase leg movements will be encouraged based on the infant's developmental level and what they demonstrate a response to, including: shake a toy when infant moves legs, sing a line of a song when infant moves legs, change the position of the infant to encourage more leg movement, or lightly tickle the legs and feet of the infant. The intervention will use the GAME (Goals - Activity - Motor Enrichment) protocol, a motor learning, environmental enrichment intervention that has recently been shown to be effective for improving motor skills in infants at high risk of cerebral palsy compared to standard care.
