Abstract:Recent
studies have demonstrated that home-based rehabilitation for stroke
patients has excellent potential in reducing the cost and enhancing
rehabilitation efficiency. Nonetheless, a timely and accurate
rehabilitation assessment is required to attain efficacy and provide
feedback to both clinicians and patients. In this paper, a lower limb
motor function assessment approach based on limb kinematic data has been
presented. The kinematic characteristics of lower limbs were quantified
into specific evaluation parameters, which were calculated during a set
of selected rehabilitation exercises. A body area network composed of
two triaxial accelerometers was used to acquire the limb kinematic data
of twenty stroke patients and six healthy subjects. While a referenced
template was developed using the data from healthy subjects, an
empirical score was obtained to evaluate the lower-limb motor function
of stroke patients from the calculated parameters. The results have
demonstrated that the scoring has a statistically significant strong
correlation with the Brunnstrom stage classification, which provides a
practical quantitative evaluation approach for home-based rehabilitation
for lower limbs of stroke patients.Clinical Relevance— The proposed
quality assessment method provides practical technical support for
performing early support discharge rehabilitation.
