Musculoligamentous Origin: Methods for Treating Pain or Restoring Health, Medications, Rehabilitation Instruments, or Rehabilitation Equipment

I. Clinical Manifestations and Pathological Mechanisms

The symptoms you described are highly consistent with the typical presentation of what is medically termed “lumbar muscle strain,” “myofascial pain syndrome of the lower back,” or “lumbosacral sprain.”

• Core Features: Pain is usually confined to the lower back or buttocks and does not radiate below the knee. Musculoligamentous low back pain originates from mechanical injury or chronic aseptic inflammation of the paraspinal muscles, fascia, ligaments, or joint capsules. The pain is typically not accompanied by progressive neurological deficits (such as foot drop or bowel/bladder dysfunction).

• Common Triggers:

  • Acute Injury: Sudden violence during bending to lift heavy objects, or sudden twisting, causing violent muscle contraction or ligament tears.

  • Chronic Strain: Long-term poor posture (prolonged sitting, prolonged standing) or repetitive loading leading to cumulative damage to muscles and fascia.

II. Pharmacological Treatment Options

Medications are primarily used to relieve acute-phase pain and muscle spasms and are generally recommended for short-term use (typically no more than 6 weeks for acute injuries).

• Non-Steroidal Anti-Inflammatory Drugs (NSAIDs): These are first-line medications for controlling inflammation and pain. Commonly used drugs include ibuprofen, diclofenac sodium, and celecoxib. Their action is to inhibit prostaglandin synthesis, thereby exerting anti-inflammatory and analgesic effects. Note: Long-term use (exceeding 3-6 months) may increase the risk of gastrointestinal bleeding or ulcers, and should be used under medical supervision.

• Muscle Relaxants: When significant muscle spasm is present (hard, intensely tender lower back muscles), these may be used in combination. Examples include methocarbamol or eperisone hydrochloride. These drugs help break the vicious cycle of “pain-spasm-more pain” and facilitate subsequent physical therapy. However, they cannot shorten the healing time of the injury itself and may cause drowsiness.

• Traditional Chinese Patent Medicines and Topical Agents: Chinese herbal formulations with actions of soothing tendons, invigorating blood circulation, and relieving pain, or topical plasters, may serve as adjunctive treatment methods.

III. Rehabilitation Therapy and Physical Modality Treatment

Physical therapy is the core rehabilitation approach for musculoligamentous low back pain, aimed at relieving pain, releasing adhesions, and improving circulation.

• Extracorporeal Shockwave Therapy (ESWT): Relatively high level of evidence. Utilizes mechanical pressure generated by high-energy acoustic waves to release adherent lesional tissue and stimulate the release of analgesic substances (substance P). Typically administered once every 4-7 days, with 3-5 sessions constituting one treatment course.

• Electrotherapy (Low-Frequency/Medium-Frequency/High-Frequency): Uses electrical current stimulation to produce skeletal muscle contraction or promote local blood circulation, used to relieve muscle spasm and prevent muscle atrophy. Among these, Transcutaneous Electrical Nerve Stimulation (TENS) is commonly used for acute and chronic pain control.

• Laser and Ultrasound: High-energy laser can promote local blood vessel growth and healing and relieve pain; ultrasound promotes tissue repair through micro-massage and thermal effects. Ultrasound-mediated drug phonophoresis is particularly effective for acute sprains and fasciitis.

• Others: Wax therapy, water-filtered infrared A (wIRA), and specific electromagnetic wave (TDP) therapy may serve as part of comprehensive treatment. However, they are not recommended as standalone treatments and should be combined with active training or other therapeutic modalities.

IV. Rehabilitation Training and Equipment

Core Principle: In the acute phase, rest and symptom relief are the priority; in the recovery phase and chronic phase, active lumbar-back muscle exercises are the key to preventing recurrence and stabilizing the spine.

• Dynamic Neuromuscular Stabilization (DNS): This is a manual rehabilitation technique based on human motor ontogenesis, emphasizing the reconstruction of innate neuromuscular pathways. Studies have shown that DNS training combined with Kinesio Taping (KT) can significantly improve pain, dysfunction, and spinal stability in chronic non-specific low back pain, with effects superior to conventional treatment alone.

• Traditional Lumbar-Back Muscle Functional Exercises: Such as the “superman exercise” (prone extension) and the “five-point support method,” aimed at strengthening the erector spinae and multifidus muscles to provide dynamic protection for the spine.

• Rehabilitation Assistive Devices:

  • Sling Suspension Training System: Used for core muscle training under unstable conditions.

  • Kinesio Taping (KT): As an adjunctive method, it can relieve pain, improve proprioception, and joint range of motion.

V. Key Indicators for Seeking Medical Attention

Although musculoligamentous low back pain is mostly benign, if the following conditions occur, other serious etiologies should be considered and medical attention should be sought promptly:

1. Pain persists for more than 2-4 weeks without improvement.

2. Pain is accompanied by radiating leg pain, numbness, or weakness.

3. Accompanied by unexplained weight loss, fever, or night resting pain.
