Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to reveal the effectiveness and safety of integrative Korean medicine for Ossification of Posterior Longitudinal Ligament(OPLL) by observation inpatients treated with integrative Korean medicine.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Numeric rating scale (NRS) | NRS uses an 11-point scale to evaluate current neck pain and radiating pain where no pain is indicated by '0', and the worst pain imaginable by '10'. NRS was assessed at admission, 2 weeks after admission, discharge, and long term follow up. | Finish survey by September 2020 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Vernon-Mior Neck Disability Index (NDI) | NDI is a 10-item questionnaire developed to evaluate the degree of disability for neck back pain. Each item is divided into 6 levels, and 0 to 5 points are awarded. The higher the score, the greater the degree of disability. We will conduct an validated Korean NDI questionnaire | Finish survey by September 2020 | 
| The five level version of EuroQol-5 Dimension (EQ-5D) | EQ-5D is most widely used as a method of indirectly calculating the quality of life from various aspects. The EQ-5D-5L consists of 5 questions (mobility, self-care, usual activities, pain, anxiety/depression) that ask about the current state of health, and answers each question with 5 likert. (1=I have no problems about, 2=I have slight problems about, 3=I have moderate problems about, 4=I have severe problems about, 5=I am unable to about) In this study, the validated Korean version questionnaire will be used. | Finish survey by September 2020 | 
| Patient Global Impression of Change (PGIC) | PGIC is an indicator that evaluates the improvement of patients in 7 steps, and the subject responds with improvement of functional limitation after treatment with 7 likert. (1=very much improved, 2=much improved, 3=minimally improved, 4=no change, 5=minimally worse, 6=much worse, 7=very much worse). | Finish survey by September 2020 | 
| Spine surgery | The number of spinal surgery after discharge | Finish survey by September 2020 | 
| Current symptoms survey | Pain, neurological problems, etc. | Finish survey by September 2020 | 
| Treatment after discharge survey | Treatment history in the last 3 month | Finish survey by September 2020 |
