Quantitative measures of sagittal plane head-neck control: A test-retest reliability study

摘要: Abstract Determining the reliability of measurements used to quantify head–neck motor control is necessary before they can be study effects injury or treatment interventions. Thus, purpose this was determine within- and between-day position tracking, stabilization force tracking tasks control. Ten asymptomatic subjects performed these on two separate days. Position required track a pseudorandom square wave input signal by controlling their angular (position tracking) magnitude isometric generated against sensor neck musculature (force in sagittal plane. maintain an upright head while perturbations were applied upper body using robotic platform. Within-day frequency response curves assessed coefficients multiple correlations (CMC). Root mean error (RMSE) bandpass energy, computed for each task calculated intra-class correlation (ICC). Within- CMCs all ≥0.96, ranged from 0.72 0.82. ICCs ≥0.93. For stabilization, RMSE energy 0.66 0.72, respectively. Measures plane demonstrated reliable.
