摘要

Purpose

To establish the intrasession reliability of a multidimensional visual biofeedback (VBFB) across various kinetic and kinematic metrics during static and dynamic postural control tasks.

Methods

Nine healthy, physically active young adults (3 males, 6 females; Age: 21.8 ± 1.39 years; Height: 169.3 ± 8.8 cm; Weight: 68.54 ± 9.14 kg) performed static and dynamic balance tasks with and without VBFB. Center of Pressure (COP) data and torso kinematic data were captured to determine both relative and absolute reliability, which included intra-class correlation coefficients (ICC), standard error of measurement (SEM), coefficient of variation (CV), and minimal detectable change (MDC95).

Results

The dynamic balance conditions yielded higher relative (ICCs mean: 0.927, range: 0.589–0.994) and absolute reliability (CVs mean: 25.51, range: 1.17–124.650) than those from the static conditions (ICCs mean: 0.850, range: 0.594–0.973; CVs mean: 37.57, range: 1.61–209.44). The presence of VBFB lowered the relative reliability (ICCs mean: 0.860, range: 0.589–0.979) and absolute reliability (CVs mean: 36.44, range: 1.72–209.44) compared to the absence of VBFB conditions (ICCs mean: 0.919, range: 0.594–0.994; CVs mean: 26.64, range: 1.17–111.59), indicating the potential complexity and novelty of VBFB.

Conclusion

Using multidimensional VBFB produced moderate to excellent intrasession performance for static and dynamic balance tasks with the latter yielding more consistent measurements. The results provide evidence for the application of multidimensional VBFB in postural control training programs that may target individuals with elevated fall risks.
