Stroke is the third cause of death in contemporary society and causes many disorders. Clinical scales, ground reaction force (GRF) and objective gait analysis are used for assessment of patient’s rehabilitation progress during treatment. The goal of this paper is to assess whether signal correlation coefficient matrix applied to GRF can be used for evaluation of post-stroke patients status. Group of patients underwent clinical assessment and instrumented gait analysis simultaneously three times. The difference between components of patient’s GRF (vertical, fore/aft, med/lat) and normal ones (reference GRF of healthy subjects) was calculated as correlation coefficient. Patients were divided into two groups (“worse and better”) based on the clinical functional scales tests done at the beginning of rehabilitation process. The results obtained by these two groups were compared using statistical analysis. Increase of median value of correlation coefficient is observed in all components of GRF, but only in non-paretic leg. Analysis of GRF signal can be helpful in assessment of post-stroke patients during rehabilitation. Improvement in stroke patients was observed in non-paretic leg of the “worse” group. GRF analysis should not be the only tool for objective validation of patient’s improvement, but could be used as additional source of information.
