Summary
Preterm infants show delayed segmental trunk control development compared to full-term infants. Early intervention focusing on trunk control and motor skills is crucial for improving outcomes in infants with motor delays.
Area of Science:
- Developmental Pediatrics
- Motor Control Research
- Neonatal Development
Background:
- Segmental trunk control is crucial for infant motor development.
- Limited research exists on trunk control development in preterm infants.
Purpose of the Study:
- To longitudinally examine segmental trunk control development in preterm infants compared to full-term infants.
- To assess trunk control from 4 to 12 months corrected age.
Main Methods:
- Recruited 31 preterm and 30 full-term infants.
- Utilized the Segmental Assessment of Trunk Control and Alberta Infant Motor Scale monthly.
- Tested infants at 4, 8, and 12 months corrected age.
Main Results:
- Preterm infants exhibited significantly delayed segmental trunk control.
- Positive correlations were observed between trunk control and gross motor skills.
- Segmental trunk control and gross motor performance are coupled in infants.
Conclusions:
- This is the first study demonstrating significantly different segmental trunk control development in preterm infants.
- Therapeutic interventions should integrate training of upright trunk control and specific motor skills.
- A dual-focus approach may optimize therapy outcomes for infants with motor delays.

483
Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...

02:20Longitudinal Research
13.1K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

01:21Pilot and Numeric Relaying
483
Pilot relaying is a type of differential protection used in power systems. It compares electrical quantities at the terminals of equipment via a communication channel instead of direct relay interconnection. This method is essential for transmission lines where the terminals are far apart, typically up to 80 km for lines with 69 to 115 kV ratings. Four types of communication channels are used for pilot relaying:

414
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

01:05Long-term Depression
33.2K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.
