Uncertainty in Measurement: Reading Instruments

Counting is the type of measurement that is free from uncertainty, provided the number of objects being counted does not change during the process. Such measurements result in exact numbers. By counting the eggs in a carton, for instance, one can determine exactly how many eggs are there in the carton. Similarly, the numbers of defined quantities are also exact. For example, 1 foot is exactly 12 inches, 1 inch is exactly 2.54 centimeters, and 1 gram is exactly 0.001 kilograms. Quantities...

Area of Science:

  • Biomechanics and Movement Science
  • Wearable Technology in Healthcare
  • Clinical Assessment Tools

Background:

  • Turning is a fundamental component of daily mobility and a key indicator of functional independence.
  • Impaired turning is associated with an increased risk of falls and reduced quality of life.
  • Objective and reliable methods for quantifying turning performance are needed for clinical evaluation.

Purpose of the Study:

  • To determine the test-retest reliability of turning performance metrics derived from wearable inertial sensors.
  • To assess the reliability of these metrics across various ecologically valid turning tasks.
  • To evaluate the potential of wearable sensors for clinical use in assessing turning ability.

Main Methods:

  • Seventy-one healthy adults performed three turning tasks: a 1-minute walk, a modified Illinois Agility Test (mIAT), and a complex turning course (CTC).
  • Wearable inertial sensors placed on the head, trunk, and lumbar spine captured peak axial turning and rotational velocity (yaw angular velocity).
  • Intraclass correlation coefficients (ICCs) were calculated to assess the test-retest reliability of average peak turning speed and lap times.

Main Results:

  • Turning speed demonstrated good to excellent reliability across all tasks, with the highest reliability observed in the CTC (ICCs ranging from 0.71 to 0.83).
  • Reliability for 180-degree turns during the 1-minute walk was consistent across body segments (ICCs 0.74-0.76).
  • The mIAT showed fair to excellent reliability (ICCs 0.50-0.84), and lap times for both CTC (ICC 0.69) and mIAT (ICC 0.91) were reliable.

Conclusions:

  • Turning speed measured by wearable inertial sensors is a reliable outcome measure for various ecologically valid turning tasks.
  • These wearable sensor metrics are easily testable in a clinical setting, offering a practical approach to assessing turning performance.
  • Turning performance, reliably quantified by inertial sensors, should be integrated into clinical assessments and trials to enhance patient evaluation and research.
