Summary

This summary is machine-generated.

This review highlights inconsistencies in estimating physiological time delays within the human sensorimotor system. Standardization is needed for accurate delay estimation and prediction in future research.

Area Of Science

  • Neuroscience
  • Biomechanics
  • Control Systems Engineering

Background

  • The human sensorimotor system navigates complexities like noise, non-linearities, and delays.
  • Physiological time delays (sensory, transmission, CNS, muscle activation) are crucial for biomechanical stability.
  • Current literature shows significant discrepancies in methods for estimating and predicting these time delays.

Purpose Of The Study

  • To systematically characterize and categorize existing approaches for estimating physiological time delays.
  • To identify heterogeneity and variability in the definition, experimental protocols, and estimation values of time delays.
  • To call for standardization in future scientific endeavors concerning physiological time delay estimation.

Main Methods

  • A scoping review adhering to PRISMA guidelines.
  • Searched five databases (EMBASE, PubMed, Scopus, IEEE, Web of Science) from 2000-2022 using relevant keywords.
  • Analyzed 46 selected articles using 20 quantification and 16 qualification questions by two independent reviewers.

Main Results

  • Reviewed studies exhibited heterogeneity in defining time delays and variability in experimental protocols and delay values.
  • Most analyzed articles were of high quality, employing diverse analytical methods (optimization, regression, Kalman filters, neural networks).
  • Over 50% of studies failed to clearly define the nature of the time delays being estimated.

Conclusions

  • Significant variability and lack of clear definitions hinder consistent physiological time delay estimation.
  • Standardization of methodologies and definitions is essential for advancing research in sensorimotor control.
  • Future research should prioritize clear definitions and standardized protocols for reliable time delay quantification.
