The purpose of this study is to investigate the efficacy of using Korean medicine treatment with post-concussion syndrome. We primarily treated the patient’s post-concussion syndrome during hospitalization (22.04–22.11.11) with Korean medicine treatments (herbal medicine, acupuncture, and Chuna therapy). The KHIT-6 and Numeric Rating Scale were used to assess symptom (headache, dizziness, and nausea) changes. Following treatment, the patient’s KHIT-6 and Numeric Rating Scale scores decreased. This study suggests that Korean medicine may be effective in the treatment of post-concussion syndrome.
