Clinical Trial Summary

This observational study will assess the long-term course and effect of Korean medicine treatment in lumbar intervertebral disc herniation patients who received integrative Korean medicine treatment for 24 weeks as part of a previous clinical study.


Description:

This observational study will assess the long-term course and effect of Korean medicine treatment in lumbar intervertebral disc herniation patients with a main complaint of radiating leg pain who received integrative Korean medicine treatment for 24 weeks at Jaseng Hospital of Korean Medicine (Gangnam main branch) as part of a previous clinical study which was conducted from November, 2006 to April, 2007, and give written informed consent to long-term follow-up assessment at 10 years.

Study Design


Intervention

Diagnostic Test:
Magnetic Resonance Imaging (MRI)
Changes in size and severity of the main herniated disc causing radiating pain will be evaluated by radiology specialists and Korean medicine doctors (KMDs) and categorized into three groups (improved, worse or no discernible change) in comparison with the immediate previous MRI to track long-term changes and assess for correlations in subjective clinical symptoms and objective physical evaluation and MRI results.

Outcome

Type Measure Description Time frame Safety issue
Primary Change in Visual Analogue Scale (VAS) of radiating leg pain Visual Analogue Scale (VAS) uses a 10cm line labeled at each end with scale anchors. In pain measurement using VAS, patients are asked to mark a point that represents their pain between the anchors of 'no pain (minimum score: 0)' and 'worst pain imaginable (maximum score: 100)'. Total scores are recorded in millimeters with a total range of 0-100 millimeters. Higher VAS values represent more severe pain, and a greater change from baseline (If baseline - follow up is a positive value) indicates a better outcome. Difference from baseline at 10 years
Secondary Visual Analogue Scale (VAS) of low back pain Visual Analogue Scale (VAS) uses a 10cm line labeled at each end with scale anchors. In pain measurement using VAS, patients are asked to mark a point that represents their pain between the anchors of 'no pain (minimum score: 0)' and 'worst pain imaginable (maximum score: 100)'. Total scores are recorded in millimeters with a total range of 0-100 millimeters. Higher VAS values represent more severe pain. Baseline, and 10 years
Secondary Visual Analogue Scale (VAS) of radiating leg pain Visual Analogue Scale (VAS) uses a 10cm line labeled at each end with scale anchors. In pain measurement using VAS, patients are asked to mark a point that represents their pain between the anchors of 'no pain (minimum score: 0)' and 'worst pain imaginable (maximum score: 100)'. Total scores are recorded in millimeters with a total range of 0-100 millimeters. Higher VAS values represent more severe pain. Baseline, and 10 years
Secondary Numeric Rating Scale (NRS) of low back pain In pain measurement using Numeric Rating Scale (NRS), patients are asked to rate their pain by selecting a number from 0 to 10 that best represents their pain severity between the anchors of 0 which indicates 'no pain', and 10 which indicates 'worst pain possible'. Baseline, and 10 years
Secondary Numeric Rating Scale (NRS) of radiating leg pain In pain measurement using Numeric Rating Scale (NRS), patients are asked to rate their pain by selecting a number from 0 to 10 that best represents their pain severity between the anchors of 0 (minimum score) which indicates 'no pain', and 10 (maximum score) which indicates 'worst pain possible'. Higher NRS values represent more severe pain. Baseline, and 10 years
Secondary Oswestry Disability Index (ODI) The ODI is a 10-item questionnaire developed to assess level of disability due to low back pain (LBP). Each item is graded into 6 levels, each representing a score of 0-5. Higher scores indicate greater limitation relating to LBP. Baseline, 10 years
Secondary 36-Item Short Form Survey (SF-36) SF-36 consists of 36 items across 8 domains: physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional, and mental health. SF-36 is used to rate functional health and well-being in patients and healthy individuals. Higher scores indicate better HRQoL. Baseline, 10 years
Secondary Patient Global Impression of Change (PGIC) PGIC grades the level of subjective improvement into 7 levels (1, very much improved; 2, much improved; 3, slightly improved; 4, no change; 5, slightly worse; 6, much worse; and 7, very much worse). Baseline, 10 years
Secondary Lumbar range of movement (ROM) ROM measurements are valid (r=0.97) and reliable (r=0.94), but not highly responsive (effect size=0.1-0.6). If ROM is uncheckable from pain, the angle will be recorded as 0°. Baseline, 10 years
Secondary Straight leg raise (SLR) test While SLR measurements are reliable (intraclass correlation coefficient=0.95), they are not very responsive (effect size=0.2). If SLR is uncheckable from pain, the angle will be recorded as 0°. Baseline, 10 years
Secondary Qualitative questionnaire on 10 year course The qualitative questionnaire on 10 year course and outcome since receiving integrative Korean medicine treatment used in this study is a 14-item descriptive evaluation encompassing various items (a mixture of short-answer questions, multiple choices, and transcript of essay form answers) on the change before and after treatment over the course of 10 years (e.g. change in perception of surgery and non-surgical treatment, change in everyday life or habits, and treatment recommendation to others). 10 years
Secondary Medical history Physicians will rate the causal relationship of each treatment from the previous clinical study with the patient's medical history potentially associated with treatment on a 6-point scale (1, definitely related; 2, probably related; 3, possibly related; 4, probably not related; 5, definitely not related; and 6, unknown), and classify all medical history potentially associated with treatment with the Spilker classification, which has 3 grades (1, mild: no intervention needed and does not greatly impede normal activity (function) of patient; 2, moderate: significantly impedes normal activity (function) of patient, and may need intervention, with subsequent resolution; 3, severe: severe adverse event needing intensive intervention, leaving sequela). 10 years
Secondary Adverse events Adverse events potentially associated with MRI will be assessed. 10 years
