The Effect of Low Back Pain Daoyin Exercise Based on the Theory of Goal Attainment on Patients with Lumbar Disc Herniation: Study protocol of a randomized controlled trial

This paper outlines the protocol for a randomized controlled trial designed to evaluate the efficacy and underlying neuromuscular mechanisms of a 6-week Daoyin exercise program, grounded in the theory of goal attainment, compared to core stability exercises for improving pain and functional outcomes in patients with lumbar disc herniation.

The Gist

Imagine your lower back is like the foundation of a house. When that foundation gets cracked (a condition called Lumbar Disc Herniation, or LDH), the whole house starts to creak, groan, and feel unstable. This causes pain, makes it hard to walk, and can even make you feel anxious or down.

For years, doctors have treated this "cracked foundation" with painkillers (which are like putting a temporary patch over a leak) or standard exercises. But there's a new, ancient approach being tested: Daoyin.

Think of Daoyin not just as exercise, but as "internal yoga." It's a traditional Chinese practice that combines slow, flowing movements with deep breathing and mental focus. It's like tuning a musical instrument: you aren't just tightening the strings (muscles); you are adjusting the tension, the breath, and the mind all at once to make the whole system sing in harmony again.

The Big Experiment: A Race Between Two Teams

The authors of this paper are setting up a scientific race to see if this ancient "tuning" method works better than modern "bracing" methods.

• Team A (The Daoyin Group): These participants will learn a specific set of 5 gentle, flowing movements designed just for back pain. They will practice these moves like a dance, focusing on breathing and mind-body connection.
• Team B (The Control Group): These participants will do Core Stability Exercises (CSE). Think of this as building a strong, rigid steel frame around the house. These are standard, proven exercises (like planks and bridges) that strengthen the muscles to hold the spine steady.

The Twist: To make sure Team A actually sticks to their routine, the researchers are using a special coaching strategy called the Theory of Goal Attainment (TGA).

• The Analogy: Imagine a personal trainer who doesn't just yell "do 20 pushups!" but instead sits down with you, listens to your fears, helps you set your own goals, and creates a plan with you. This "partnership" approach is designed to make people want to keep exercising, rather than feeling forced to do it.

The 6-Week Challenge

The study will last six weeks. Here is the game plan:

1. Weeks 1-2 (Training Camp): Both groups meet five times a week for 30 minutes to learn their moves under expert guidance.
2. Weeks 3-6 (Home Practice): Participants go home and practice on their own, with videos and phone check-ins to keep them on track.

How Do They Measure Success? (The "Dashboard")

The researchers aren't just asking, "Does it hurt less?" They are using a high-tech dashboard to measure the "health of the house" in three different ways:

1. The Pain Meter (Subjective): They ask patients to rate their pain on a scale of 0 to 10. This is the "feeling" check.
2. The Muscle & Movement Sensors (Objective):
   • sEMG: Tiny sensors stick to the skin to listen to the muscles "talking." Are the back muscles firing correctly? Are they working in sync with the belly muscles?
   • Gait Analysis: They will watch the patients walk with high-speed cameras to see if their stride is smoother and more balanced.
3. The Brain Scan (The "Pain Center"): This is the most futuristic part. They will use EEG (brain waves) to look at the brain's electrical activity.
   • The Analogy: Pain isn't just in the back; it's also in the brain. Sometimes the brain gets stuck in a "pain loop," like a radio playing a sad song on repeat. The researchers want to see if Daoyin changes the brain's radio station, turning down the volume on the pain signals.

Why Does This Matter?

Right now, we know exercise helps back pain, but we don't fully understand why or if ancient practices like Daoyin are a secret weapon we've been ignoring.

If this study shows that the "Internal Tuning" (Daoyin) works as well as or better than the "Steel Frame" (Core Exercises), it could change how doctors treat back pain forever. It would mean that instead of just taking pills or doing boring gym reps, patients could learn a mindful, breathing-based movement that heals the body and calms the mind.

In short: This paper is a blueprint for a scientific test to see if an ancient Chinese dance of breath and movement can fix a modern back problem, using high-tech brain scans and muscle sensors to prove it works.

Technical Summary

Based on the provided study protocol, here is a detailed technical summary of the research:

1. Problem Statement

• Clinical Burden: Lumbar Disc Herniation (LDH) is a prevalent condition causing low back pain (LBP), radiating neuropathic pain, and functional limitations. It poses a significant global health threat, leading to productivity loss, disability, and psychological distress.
• Limitations of Current Treatments: While non-surgical treatments like NSAIDs and muscle relaxants are common, they often offer only temporary relief with potential side effects. Exercise therapy is recommended as a first-line treatment, but existing evidence for traditional Chinese exercises (Daoyin) is limited by low methodological quality and a lack of objective outcome measures.
• Theoretical Gap: There is a scarcity of rigorous Randomized Controlled Trials (RCTs) investigating Daoyin specifically tailored for LDH patients. Furthermore, the application of the Theory of Goal Attainment (TGA)—a framework designed to enhance patient adherence through nurse-patient collaboration—has not been sufficiently explored in the context of LBP management.

2. Methodology

• Study Design: A randomized, controlled, single-blind clinical trial.
• Participants:
  • Target: 66 patients with chronic LDH (aged 18–75), confirmed via CT/MRI.
  • Exclusion: Other causes of LBP (e.g., tumors, stenosis), severe comorbidities, or recent participation in other traditional Chinese exercises.
  • Recruitment: Shandong University of Traditional Chinese Medicine Affiliated Hospital and surrounding communities.
• Intervention Groups (1:1 Allocation):
  • Experimental Group (Daoyin): Participants perform a TGA-based Daoyin protocol consisting of five structured movements (e.g., "Rowing with Both Elbows").
    • Phase 1: 2 weeks of supervised training (30 mins, 5x/week) with an instructor.
    • Phase 2: 4 weeks of home practice (3x/week) supported by instructional videos and WeChat feedback.
  • Control Group (Core Stability Exercise - CSE): Participants perform standard CSE (Cat-Cow, Modified Plank, Glute Bridge, Dead Bug, Bird-Dog) under physiotherapist guidance.
    • Schedule: Matches the Daoyin group (30 mins, 5x/week for 2 weeks supervised, followed by home practice).
• Theoretical Framework: The Theory of Goal Attainment (TGA) is integrated into the Daoyin intervention. It involves a 5-stage process (assessment, diagnosis, planning, implementation, evaluation) where nurses and patients collaboratively set goals to improve adherence and self-management.
• Outcome Measures:
  • Primary Outcome: Pain intensity at 6 weeks, measured by the Visual Analogue Scale (VAS).
  • Secondary Outcomes:
    • Functional: Japanese Orthopaedic Association (JOA) score, Oswestry Disability Index (ODI).
    • Quality of Life & Psych: SF-36, Hospital Anxiety and Depression Scale (HADS).
    • Objective Physiological Metrics:
      • Surface Electromyography (sEMG): Assessing muscle activity (RMS, Median Frequency) and coordination (Flexion-Relaxation Ratio, Co-contraction index) of lumbar and abdominal muscles.
      • 3D Gait Analysis: Kinematic parameters (step length, speed, stride length) and pelvic coordination.
      • Electroencephalography (EEG): Monitoring brain activity (θ, α, β, γ bands) during resting and task states to objectively assess pain sensitivity and neural correlates of pain.
• Statistical Analysis:
  • Sample Size: Calculated for 90% power to detect an effect size of 0.86 (VAS change), accounting for a 10% dropout rate.
  • Model: Generalized Estimating Equation (GEE) to analyze longitudinal changes and group-by-time interactions.
  • Principle: Intention-to-Treat (ITT) with multiple imputation for missing data.

3. Key Contributions

• Novel Integration: This is the first RCT to combine Daoyin exercise with the Theory of Goal Attainment (TGA) specifically for LDH, aiming to bridge the gap between traditional exercise and modern behavioral change theory.
• Multimodal Objective Assessment: Unlike previous studies relying solely on self-reported scales, this protocol incorporates high-tech objective biomarkers:
  • EEG to quantify central nervous system responses to pain.
  • sEMG to measure neuromuscular efficiency and muscle coordination.
  • 3D Gait Analysis to evaluate biomechanical alterations in walking patterns.
• Rigorous Design: The study adheres to SPIRIT guidelines, employs single-blinding (assessors and analysts), uses a computer-generated randomization sequence, and includes a well-matched active control (CSE) to ensure internal validity.

4. Results

• Status: No results are reported in this document.
• Reason: This paper is a Study Protocol. It outlines the design, methodology, and analysis plan of the trial. The trial is currently ongoing (recruitment started July 2025, planned conclusion May 2026). The document explicitly states it reports new research that has not yet been certified by peer review or completed.

5. Significance

• Clinical Evidence: If successful, the study will provide high-quality evidence (Level 1) regarding the efficacy of Daoyin for LDH, potentially establishing it as a viable first-line or adjunctive therapy.
• Mechanistic Insight: By utilizing EEG, sEMG, and gait analysis, the study aims to elucidate the neuromuscular mechanisms underlying Daoyin's effects, moving beyond subjective symptom reporting to objective physiological validation.
• Behavioral Innovation: Demonstrating the efficacy of TGA in exercise adherence could revolutionize how chronic pain management programs are structured, emphasizing collaborative goal-setting over prescriptive instruction.
• Future Research: The findings will inform the design of large-scale multicenter trials and contribute to a solid evidence base for the broader clinical application of traditional Chinese medicine exercises in modern rehabilitation.
