PURPOSE Ambulatory biofeedback has potential to improve carryover of newly established vocal motor behaviors into daily life outside of the clinic and warrants systematic research that is lacking in the literature. This proof-of-concept study was designed to establish an empirical basis for future work in this area by formally assessing whether ambulatory biofeedback reduces daily vocal intensi...

BACKGROUND Infants may be at neurodevelopmental risk from adverse events arising in the neonatal period. This study aimed to investigate the developmental outcomes and physical activity behaviours of term infants after neonatal major surgery, at age three years. METHODS This prospective study enrolled infants who underwent major surgery in their first 90 days, between August 2006 and December...

Knee-flexor motor activity rhythmically alternated with knee-extensor motor activity during fictive rostral scratching in the spinal turtle. A critical transition from knee-flexor motor activity to knee-extensor motor activity occurred during hip-flexor motor activity. A key feature of this transition was that the end-phases of knee-flexor motor activity were positively correlated with the star...

OBJECTIVE In order to effectively promote physical activity (PA) during childhood, and across the lifespan, a better understanding of the role of early motor skill development on child and adult PA is needed. METHODS Here, we propose a conceptual model delineating the hypothesized influence of motor skill development on child and adult PA, while providing an overview of the current empirical ...

We describe here the robust synchronization of motor neurons at a millisecond time scale during locomotor activity in the neonatal rat. Action potential activity of motor neuron pairs was recorded extracellularly using tetrodes during locomotor activity in the in vitro neonatal rat spinal cord. Approximately 40% of motor neuron pairs recorded in the same spinal segment showed significant synchr...
