In Donguibogam, a representative encyclopedic source of knowledge on traditional Korean medicine, left-sided hemiparesis due to stroke is called "Tan" as a sort of "Heyol-Byeong," while right-sided hemiparesis due to stroke is called "Tan" as a sort of "Gi-Byeong." According to the theory of Donguibogam, diseases on the left or right side of the human body must be treated differently. Clinically, the symptoms caused by left and right hemisphere lesions in stroke patients differ, as the functions of the left and right hemispheres differ. Considering these facts, when treating patients in clinical practice, it may be useful to distinguish between diseases on the left or right side according to Donguibogam. This study set out to confirm whether side-dependent gait rehabilitation could be used to treat hemiparetic stroke patients. Gait was selected for analysis, as it is the most important factor in returning stroke patients to daily life.This study conducted a retrospective chart review of stroke patients who satisfied the following criteria: outpatient or inpatient at the Wonkwang University Korean Medicine Hospital in Gwangju (WKUGH) with hemiparesis due to stroke; aged between 19 and 85 years old; with a stroke onset within the past 6 months; having undergone gait analysis (GAITRite) more than twice between September 1, 2017 and June 30, 2018 at the WKUGH, with a minimum 2-week interval between the first and next gait analysis; right-handed stroke patient; able to walk unaided. The spatio-temporal parameters for analysis included the FAP, walking velocity, step length, stance time, and swing time as obtained with GAITRite.In the initial gait analysis, there was no significant difference between the 2 groups in all spatio-temporal parameters. However, in the follow-up gait analysis, the left hemiparesis group showed a significantly higher FAP and faster walking velocity than the right hemiparesis group.This study found a difference in the recovery rate between the left and right hemiparesis groups. Based on this, we suggest that a different treatment strategy for gait rehabilitation can be used according to the paralyzed side.This study was approved by the Institutional Review Board (IRB) of the Wonkwang University Korean Medicine Hospital in Gwangju (WKUGH), Republic of Korea (WKIRB 2018 - 25, November 28, 2018). This trial was registered with the Clinical Research Information Service (CRIS) of the Korea National Institute of Health (NIH), Republic of Korea (KCT0002984).
