Insights

Children with sensory modulation disorder (SMD) exhibit poorer stance control compared to typically developing peers. This study confirms impaired postural stability in children with SMD across various sensory conditions.

Area of Science:

  • Neuroscience
  • Developmental Psychology
  • Biomechanics

Background:

  • Sensory Modulation Disorder (SMD) affects sensory processing, potentially impacting motor control.
  • Postural stability is crucial for daily activities and development.
  • Previous research has not fully elucidated the impact of SMD on stance control under varied sensory conditions.

Purpose of the Study:

  • To compare stance control in children with SMD versus typically developing children.
  • To investigate the influence of visual and somatosensory conditions on postural stability.
  • To confirm and characterize stance control deficits in children with SMD.

Main Methods:

  • Recruited 17 children with SMD and 14 typically developing children.
  • Assessed sensory modulation using the Sensory Profile, electrodermal response, and Evaluation of Sensory Processing.
  • Measured postural stability using a lumbar-mounted dual-axis accelerometer.

Main Results:

  • Children with SMD demonstrated atypical sensory responses.
  • The SMD group exhibited significantly greater body sway than controls (p < .05).
  • Group differences in sway were less pronounced with reliable somatosensory input and sway-referenced vision.

Conclusions:

  • This study confirms impaired stance control in children with Sensory Modulation Disorder.
  • Findings highlight the role of sensory processing in maintaining postural stability.
  • Further research can explore interventions to improve balance in children with SMD.

Drug Dosing: Infants and Children01:29

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

What is a Sensory System?01:31

What is a Sensory System?

Sensory systems detect stimuli—such as light and sound waves—and transduce them into neural signals that can be interpreted by the nervous system. In addition to external stimuli detected by the senses, some sensory systems detect internal stimuli—such as the proprioceptors in muscles and tendons that send feedback about limb position.

Intrinsically Disordered Proteins02:18

Intrinsically Disordered Proteins

Intrinsically disordered proteins are a group of proteins that do not fold into specific three-dimensional structures. Their structural flexibility allows them to complement ordered proteins to perform functions that are inaccessible to rigid structures. They are more common in eukaryotes than prokaryotes and may either be exclusively intrinsically disordered or hybrid proteins, consisting of a mix of ordered and disordered regions. The absence of a rigid structure in these proteins can be...

Sensory Modalities01:15

Sensory Modalities

Sensation typically is the process by which the sensory receptors and sense organs detect stimuli from the internal and external environment and transmit this information to the central nervous system for processing.
General senses refer to the broad category of sensory information detected by receptors in the body and can be further grouped into somatic and visceral senses. Somatic sensations include touch, pressure, temperature, and pain and are essential for navigating our environment and...

Sensory Memory01:14

Sensory Memory

Sensory memory captures information from the environment in its original form for a very brief duration, just long enough to be exposed to visual, auditory, and other senses. This type of memory is detailed and rich but quickly lost unless certain strategies are employed to transfer it into short-term or long-term memory. Sensory information is continuously bombarding the human brain, yet only a small fraction is absorbed, as most of it does not significantly impact daily life. For instance,...

Factors Affecting Renal Clearance: Renal Impairment01:17

Factors Affecting Renal Clearance: Renal Impairment

Renal dysfunction significantly impairs the renal clearance of drugs, leading to potential complications in drug therapy. Renal failure, which can be caused by various factors, poses a significant challenge in the elimination of drugs from the body.
One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...
