Assessment of upper-body dynamic stability during walking in patients with subacute stroke

Marco Iosa, PhD, et al.

Figure 5. Mean and standard deviation of acceleration root-mean-square (RMS) ratios between RMS values evaluated along different body axes (RMSLL/RMSCC on left and RMSAP/RMSCC on right) for high functional group (HFG) (white), medium functional group (MFG) (gray), and low functional group (LFG) (grid). Stars indicate statistically significant difference between two groups highlighted by post hoc analyses performed with Bonferroni correction. RMSAP = RMS value along anteroposterior axis, RMSCC = RMS value along craniocaudal axis, RMSLL = RMS value along laterolateral axis.

In recent years, the use of accelerometers for quantitative assessment of dynamic balance during walking has been increasing. However, clinical applications of this technique have been limited by issues that have not been addressed with respect to the computation of the accelerometric parameters and their dependency on walking speed. We concentrated on these problems by analyzing the accelerations of 15 inpatients with subacute stroke who were able to walk autonomously, 15 age-matched nondisabled people, and 15 younger nondisabled adults. We highlighted key problems and possible solutions. Our findings are an important step toward transferring accelerometry from human movement analysis laboratories to clinical settings.
