About this study

Official title: Clinical Research of Effectiveness and Safety of Herbal Medicine Strategy for Chronic Low Back Pain : A Prospective, Multicenter, Pragmatic Randomized Clinical Study

This study is a pragmatic multicenter randomized controlled trial evaluating the effectiveness and safety of herbal medicine strategy for chronic low back pain, using standard Korean medicine treatment as the control.

Read the detailed description
  1. Background Chronic low back pain (CLBP) is a common musculoskeletal disorder often managed in Korean medicine. This study aims to evaluate the effectiveness and safety of herbal medicine strategies for CLBP within a real-world clinical setting. It was initiated as part of a national research project to generate evidence for insurance coverage of herbal prescriptions.
  2. Patient Recruitment and Screening Phase A total of 150 patients with CLBP lasting more than 3 months will be recruited across seven Korean medicine hospitals. Patients will be randomly assigned (1:1) to either the herbal medicine strategy group or the standard Korean medicine treatment group. Randomization will be prospective and pragmatic, with no pre-specified protocol for individual treatments.
  3. Treatment and Evaluation Phase Experimental Group (Herbal Medicine Strategy): Participants receive individualized herbal prescriptions based on clinical judgment. Medication is prescribed every 10 days for a total of 30 days. Control Group (Standard KM Treatment): Participants receive acupuncture, electroacupuncture, cupping, moxibustion, infrared therapy, and physical therapy twice weekly for 5 weeks, with slight variations allowed based on symptom severity. Treatment details and frequencies will be recorded in CRFs and assessed during and after the intervention.
  4. Follow-Up Phase Participants will be followed up after the treatment period to assess outcomes. Evaluation includes pain intensity, affected areas, quality of life, and treatment adherence.
  5. Monitoring Although the study is investigator-initiated, third-party monitoring will be conducted in accordance with HRPP and Korean GCP guidelines to ensure protocol compliance and data integrity.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Herbal Medicine StrategyProcedure or surgery

    A pragmatic intervention involving tailored herbal prescriptions created by Korean medicine doctors. The specific composition, dose, and duration of herbal medicine vary per patient, and prescriptions are adjusted according to clinical response.

  • Standard Korean Medicine TreatmentProcedure or surgery

    This includes the application of Korean medical procedures widely used for chronic low back pain:

    Acupuncture: Insertion of needles at 10-20 selected acupoints for 10-15 minutes.

    Electroacupuncture: Electrical stimulation at 3 Hz to 4 acupoints for 10-15 minutes.

    Infrared Therapy: Application of infrared rays from 30 cm for 10-15 minutes.

    Cupping: Wet or dry cupping at 2-4 points on the lower back.

    Moxibustion: Applied to two points near the painful area at 43±1°C for 10-15 minutes.

    Physical Therapy (ICT or TENS): Applied for 10-15 minutes focusing on the quadratus lumborum.

    Treatment frequency is 2 times/week for 5 weeks, but may be adjusted to 1-3 times/week depending on symptoms. Total number of sessions is limited to 10.

Study groupRoleWhat they receive
Herbal Medicine Strategy GroupExperimentalParticipants in this group will receive individualized herbal medicine prescriptions tailored to their clinical condition (symptoms, imaging, and response to treatment). Prescriptions, including type, dosage, and frequency, are determined by Korean medicine doctors based on clinical judgment. The herbal medicine will be taken orally for a total of 30 days, prescribed every 10 days over three clinic visits. All prescription details will be recorded in the CRF.
Receives: Procedure: Herbal Medicine Strategy
Standard Korean Medicine Treatment GroupActive comparatorParticipants in this group will receive standard Korean medicine treatments for chronic low back pain, including acupuncture, electroacupuncture, cupping, infrared therapy, moxibustion, and physical therapy. Treatments are provided twice weekly for 5 weeks (maximum 10 sessions), with slight adjustments allowed depending on symptom severity. Treatment protocols are based on clinician judgment, and all interventions and points used are recorded.
Receives: Procedure: Standard Korean Medicine Treatment

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Low Back Pain Numeric Rating Scale (NRS)

    The primary outcome measure will be the change in the NRS score between Baseline and Week 7, which corresponds to the first follow-up visit after the end of treatment.

    The intensity of low back pain over the past week will be assessed using the NRS. In this scale, patients select a number from 0 to 10 that best represents their current level of discomfort (0 indicates no pain, and 10 indicates the worst pain imaginable).

    Measured: Baseline(Week 0), Week 3, Week 5, Week 7, Week 12, Week 19, Week 26

  2. Oswestry Disability Index (ODI)

    The primary outcome measure will be the change in the ODI score between Baseline and Week 7, which corresponds to the first follow-up visit after the end of treatment.

    The functional status of participants will be evaluated using the ODI questionnaire, which was developed to assess the degree of disability caused by low back pain. The ODI consists of 10 items, each rated on a 6-point scale from 0 to 5. The total score is summed and then divided by the maximum possible score (50 points for 10 items) to calculate a percentage. A higher percentage indicates a greater level of disability. A validated Korean version of the ODI will be used in this study.

    Measured: Baseline(Week 0), Week 3, Week 5, Week 7, Week 12, Week 19, Week 26

Secondary outcomes (10)
  1. Radiating Leg Pain Numeric Rating Scale (NRS)

    The intensity of radiating leg pain over the past week will be assessed using the NRS. Participants will select a number from 0 to 10 that best represents their current level of discomfort (0 indicates no pain, and 10 indicates the most severe discomfort imaginable).

    Measured: Baseline(Week 0), Week 3, Week 5, Week 7, Week 12, Week 19, Week 26

  2. Low Back Pain and Radiating Leg Pain Visual Analogue Scale (VAS)

    The VAS consists of a 100 mm horizontal line where one end represents "no pain" and the other end represents "worst pain imaginable." Participants will mark a point on the line corresponding to the intensity of their low back pain and radiating leg pain during the past week.

    Measured: Baseline(Week 0), Week 7, Week 12, Week 19, Week 26

  3. Roland-Morris Disability Questionnaire-6 (RMDQ-6)

    The RMDQ-6 is a validated short-form version of the Roland-Morris Disability Questionnaire-24 (RMDQ-24) used to rapidly assess disability related to low back pain. It includes 6 items, and participants will respond based on their current condition. Higher scores indicate greater disability.

    Measured: Baseline(Week 0), Week 7, Week 12, Week 19, Week 26

  4. Patient Global Impression of Change (PGIC)

    The PGIC is a 7-point scale used to subjectively assess the patient's overall impression of improvement. The scale includes the following categories:

    1. = Very much improved,
    2. = Much improved,
    3. = Minimally improved,
    4. = No change,
    5. = Minimally worse,
    6. = Much worse,
    7. = Very much worse.

    Measured: Week 7

  5. EQ-5D-5L (EuroQol-5 Dimension, 5-Level)

    The EQ-5D-5L is a widely used instrument for assessing health-related quality of life across five domains: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each item has five levels of response. Weighted values are applied to each level to compute an index score representing the individual's overall health state.

    Measured: Baseline(Week 0), Week 3, Week 7, Week 12, Week 19, Week 26

  6. Health-related Quality of Life Instrument with 8 Items (HINT-8)

    The HINT-8 is a Korean-specific instrument developed to measure health-related quality of life, covering physical, social, mental, and positive health dimensions. It includes 8 items: climbing stairs, pain, energy, work, depression, memory, sleep, and happiness.

    Participants will choose one of four response levels per item. For example, in the stair-climbing item:

    1. = No difficulty,
    2. = Some difficulty,
    3. = Severe difficulty,
    4. = Unable to climb stairs.

    For depression:

    1. = Not depressed at all,
    2. = Occasionally depressed,
    3. = Frequently depressed,
    4. = Always depressed.

    Measured: Baseline(Week 0), Week 3, Week 7, Week 12, Week 19, Week 26

  7. Patient Health Questionnaire-15 (PHQ-15)

    The PHQ-15 is a validated Korean version of a 15-item questionnaire derived from the Patient Health Questionnaire (PHQ) used to assess general health status and somatic symptoms over the past 4 weeks. Each item is rated on a 3-point scale:

    0 = Not bothered at all,

    1. = Bothered a little,
    2. = Bothered a lot.

    The total score ranges from 0 to 30 and reflects symptom severity:

    0-4 = Minimal, 5-9 = Mild, 10-14 = Moderate, 15-30 = Severe. PHQ-15 is widely used to assess somatic symptom burden and is helpful in evaluating depression and somatoform disorders.

    Measured: Baseline(Week 0), Week 7, Week 12, Week 19, Week 26

  8. Credibility and Expectancy

    Treatment expectation will be assessed using a 9-point Likert scale. At the screening visit, participants will be asked:

    "How much do you think traditional Korean medicine treatment will relieve your symptoms?"

    Response options range from:

    1 = Not at all, 5 = Somewhat, 9 = Very much.

    Measured: Screening Visit

  9. Economic evaluation question

    Cost data will be collected using a structured questionnaire designed to measure direct medical costs (e.g., medical services), non-medical costs (e.g., transportation, caregiver expenses), informal medical costs (e.g., health supplements, devices), and productivity losses. Productivity loss will be evaluated using the Work Productivity and Activity Impairment (WPAI) questionnaire, and economic costs will be estimated for cost-effectiveness analysis.

    Measured: Baseline(Week 0), Week 3, Week 7, Week 12, Week 19, Week 26

  10. Drug Consumption

    Information on medications taken during the study period for current medical conditions will be collected at each visit, including drug name and dosage. Additionally, other treatments such as physical therapy or injections will be recorded by frequency.

    Measured: Baseline(Week 0), Week 3, Week 5, Week 7, Week 12, Week 19, Week 26
