About this study

The Korean herbal medicine is a complex extract of medicinal herbs prescribed by a Korean medicine doctor who has completed specialized education to diagnose the health condition and symptoms of patients with post-traffic accident syndromes. This treatment is known to relieve the post-accident syndromes and improve health. However, there are no studies examining the efficacy of Korean herbal medicine alone.

So, the investigators will conduct a randomized controlled trials to verify the efficacy and safety of Korean herbal medicine. From July, 2021 to May, 2022, the investigators recruited 40 patients who are suffered from post-accident syndromes with the numeric rating scale(NRS) over 5. For experimental group(the Korean herbal medicine treatment group, n=20), the investigators conducted Korean medicine treatment for 4 weeks(28 days), and for control group(the Non-Korean herbal medicine treatment group, n=20), just Korean medical treatment(acupuncture, pharmacoacupuncture, cupping, and chuna) has been conducted. For these two groups, the investigators compared NRS, Impact of Event Scale-Revised-Korean(IES-R-K), 5-level EuroQol 5-dimension(EQ-5D-5L), Short-Form-12 Health Survey version2(SF-12 v2), and Patient Global Impression of Change(PGIC).

Treatment and study plan

Korean herbal medicine treatment

Procedure

Korean herbal medicine treatment is a treatment using complex extract of medicinal herbs prescribed by a Korean medicine doctor who has completed specialized education to diagnose the health condition and symptoms of patients with post-traffic accident syndromes.

Non-Korean herbal medicine treatment

Procedure

acupuncture, pharmacoacupuncture, cupping, chuna

Primary outcomes

  1. Numeric Rating Scale(NRS) of post-accident syndromes

    Time frame: Change from baseline to 4 months

    The severity of post-accident syndrome will be assessed using NRS. NRS is a scale in which the patient indicates their subjective severity of symptoms as a whole number from 0 to 10. The participant is asked to report their severity of post-accident syndrome using NRS, where 0 indicates 'no pain or discomfort' and 10 indicates 'the most severe pain and discomfort imaginable'.

Secondary outcomes

  1. Numeric Rating Scale(NRS) of musculoskeletal complaints of post-accident syndromes

    Time frame: Baseline(week 1-1), week 3-1, week 5, week 9, week 17

    The severity of musculoskeletal complaints of post-accident syndrome will be assessed using NRS. The participant is asked to report their severity of musculoskeletal complaints(post neck pain, lower back pain, shoulder pain, knee pain, etc) using NRS, where 0 indicates 'no pain or discomfort' and 10 indicates 'the most severe pain or discomfort imaginable'.

  2. Numeric Rating Scale(NRS) of neurological complaints of post-accident syndromes

    Time frame: Baseline(week 1-1), week 3-1, week 5, week 9, week 17

    The severity of neurological complaints of post-accident syndrome will be assessed using NRS. The participant is asked to report their severity of neurological complaints(headache, dizziness, etc) using NRS, where 0 indicates 'no discomfort' and 10 indicates 'the most severe discomfort imaginable'.

  3. Numeric Rating Scale(NRS) of psychiatric complaints of post-accident syndromes

    Time frame: Baseline(week 1-1), week 3-1, week 5, week 9, week 17

    The severity of psychiatric complaints of post-accident syndrome will be assessed using NRS. The participant is asked to report their severity of psychiatric complaints(anxiety, depression, anger, insomnia etc) using NRS, where 0 indicates 'no discomfort' and 10 indicates 'the most severe discomfort imaginable'.

  4. Numeric Rating Scale(NRS) of digestive systemic complaints of post-accident syndromes

    Time frame: Baseline(week 1-1), week 3-1, week 5, week 9, week 17

    The severity of digestive systemic complaints of post-accident syndrome will be assessed using NRS. The participant is asked to report their severity of digestive systemic complaints(indigestion, loss of appetite, etc) using NRS, where 0 indicates 'no discomfort' and 10 indicates 'the most severe discomfort imaginable'.

  5. Numeric Rating Scale(NRS) of general symptoms of post-accident syndromes

    Time frame: Baseline(week 1-1), week 3-1, week 5, week 9, week 17

    The severity of general symptoms of post-accident syndrome will be assessed using NRS. The participant is asked to report their severity of general symptoms(fatigue, powerlessness, etc) using NRS, where 0 indicates 'no discomfort' and 10 indicates 'the most severe discomfort imaginable'.

  6. Impact of Event Scale-Revised-Korean (IES-R-K)

    Time frame: Baseline(week 1-1), week 3-1, week 5, week 9, week 17

    The IES-R-K is a 22-item self-report scale that evaluates subjective stress caused by traumatic events. Each item is rated on a scale of 0 (not at all) to 4 (extremely) of the severity of symptoms based on the past week, with a total score ranging from 0 to 88. Although it is not generally recommended for the diagnosis of PTSD, it is an evaluation scale widely used in trauma-related clinical studies.

  7. 5-level EuroQol 5-dimension (EQ-5D-5L)

    Time frame: Baseline(week 1-1), week 3-1, week 5, week 9, week 17

    The EQ-5D is a method of indirectly calculating the weights of certain health states for quality of life after a multidimensional investigation of health states, and is the most widely used instrument for this purpose. The EQ-5D consists of 5 questions about current health state (mobility, self-care, usual activities, pain, anxiety/depression), and each question is scored on a 5-point Likert scale (1=no problems, 3=moderate problems, 5=severe problems). In this study, the investigators will use the Korean version of the EQ-5D, which has been demonstrated to be valid.

  8. Short-Form-12 Health Survey version2 (SF-12 v2)

    Time frame: Baseline(week 1-1), week 3-1, week 5, week 9, week 17

    SF-12 version 2 is a questionnaire that evaluates health-related quality of life (HRQoL). It consists of 12 items in 8 areas (physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional and mental health).

  9. Patient Global Impression of Change (PGIC)

    Time frame: week 5, week 9, week 17

    The PGIC is an index that assesses improvements in post-accident syndromes caused by traffic accident. Participants rate the improvement in post-accident syndromes after treatment on a 7-point Likert scale (1=Very much improved, 4=No change, 7=Very much worse)

  10. Economic evaluation question

    Time frame: Through study completion, an average of 4 months

    In order to measure cost items, a questionnaire with questions measuring medical expenses, non-medical expenses, time costs, productivity loss costs, etc. is used.

  11. Drug Consumption

    Time frame: Through study completion, an average of 4 months

    Check the type and dose of drugs taken during the study period every visit

  12. Adverse events

    Time frame: Through study completion, an average of 4 months

    Check adverse events every visit
