This study required patients to meet the following inclusion criteria: (1) patients at 6 months or more after stroke, (2) unilateral stroke (infarction, hemorrhage), (3) ability to understand and perform three-step verbal instructions, and (4) ability to stand independently. Patients with severe abnormalities in their biorhythms who require inpatient treatment and those who were deemed unqualified for the study were excluded. Thirty patients who met the requirements were chosen as subjects. The subjects were randomly divided into two groups of 15 to create experimental and control groups to be respectively treated using Spine Balance 3D (CyberMedic) and Biodex Balance System (Biodex Medical Systems, Shirley, NY, USA). The random distribution of the subjects into the experimental and control groups is based on a random allocation table in the order of registration of the subjects, and the process of patient recruitment took a total of 4 months. We conducted this prospective study at the Chonbuk National University Hospital, and we notified the subjects regarding the content of the study and obtained their written consent before the experiment was conducted. The hospital's board of audit and inspection approved our study.
