Background. Ischaemic stroke is responsible for 80-85% of strokes. There is great interest in finding effective methods of rehabilitation for post-stroke patients. Objectives. The aim of this study was to assess the results of rehabilitation carried out in the normalization of upper limb muscle tonus in patients, estimated on the Ashworth Scale for Grading Spasticity. Material and Methods. The examined group consisted of 60 patients after ischaemic stroke. 10 sessions of NDT-Bobath therapy were provided within 2 weeks (ten days of therapy). Patient examinations using the Ashworth Scale for Grading Spasticity were done twice: the first time on admission and the second after the last session of the therapy to assess rehabilitation effects. Results. Among the patients involved in the study, the results measured on the Ashworth Scale (where possible) were as follows: recovery in 16 cases (26.67%), relapse in 1 case (1.67%), no measurable changes (or change within the same grade of the scale) in 8 cases (13.33%). Conclusions. Statistically significant changes were observed in the health status of the patients. These changes, in the area of muscle tone, were favorable and reflected in the outcomes of the assessment using the Ashworth Scale for Grading Spasticity (Adv Clin Exp Med 2012, 21, 4, 513-517).
