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.
