Paraplegia is a neurological dysfunction caused by traumatic spinal cord injury (SCI). It is clinically categorized into high-level paraplegia (tetraplegia) and low-level paraplegia (inferior limb paraplegia). This chapter focuses specifically on traumatic lower paraplegia, which predominantly affects bilateral lower limbs after lumbosacral spinal cord damage.
The primary etiology involves external violent trauma, such as direct spinal impact or high-altitude falls with forceful landing on the waist and buttocks. Such trauma commonly leads to vertebral fracture, spinal dislocation, and subsequent spinal cord compression and injury. Pathological changes after traumatic spinal cord damage are mainly divided into three categories.
Three Major Pathological Changes of Traumatic Spinal Cord Injury
1. Spinal Cord Shock
Spinal cord shock refers to temporary functional conduction interruption without significant anatomical structural damage. It presents clinical manifestations similar to complete transverse spinal cord injury and mainly occurs in the acute early stage of trauma. Mild cases can achieve full neurological and motor function recovery within several days to 4–6 weeks, while individual patients require a longer recovery cycle.
2. Spinal Cord Contusion and Laceration
Traumatic vertebral fracture and dislocation allow bone fragments or foreign bodies to invade the vertebral canal, causing spinal cord compression, tearing, and contusion. This results in varying degrees of intraspinal edema, hemorrhage, tissue laceration, liquefaction, and necrosis, leading to irreversible damage to the spinal cord parenchyma.
3. Secondary Spinal Cord Compression
Secondary spinal cord compression is a progressive secondary injury caused by multiple mechanical factors:
Spinal cord edema: Local inflammatory response after trauma induces tissue edema. Decreased local blood perfusion due to vertebral malformation further aggravates swelling, which typically lasts 1 to 2 weeks.
Intraspinal hemorrhage: Rupture of intradural blood vessels or epidural venous plexus causes bleeding in the acute injury phase. Gradually increased intraspinal pressure compresses the spinal cord, and persistent hemorrhage may expand compression upward and downward across multiple spinal segments.
Foreign body compression: Displaced vertebral bodies, fractured bone fragments, herniated intervertebral discs, and traumatic foreign bodies can directly compress spinal cord tissue.
Spinal arachnoid adhesion: Occurring mainly in the recovery phase, arachnoid adhesion forms due to residual intraspinal hemorrhage, softened necrotic tissue, scar hyperplasia, and long-term cerebrospinal fluid circulation obstruction, resulting in chronic spinal cord compression.
Clinical Diagnostic Criteria
Clinical manifestations vary according to injury location, trauma mechanism, and lesion severity. For lumbosacral spinal cord injuries (L1–L5, S1), spinal shock duration is relatively short, usually less than 24 hours. After shock resolution, patients present flaccid paralysis below the transverse injury level.
Patients with simple spinal concussion without structural compression can achieve favorable short-term recovery. For cases with displaced fractures and bone fragment compression, timely surgical reduction and debridement are required. Postoperative residual paraplegia manifests as complete flaccid paralysis of muscles below the injured spinal segment, consistent with preoperative neurological deficits.
Patients with mild spinal cord injury or short-term hematoma compression can obtain significant motor function recovery through standardized acupuncture rehabilitation after timely surgical decompression. In cases of severe spinal cord damage, bilateral lower limb muscular atrophy develops rapidly: paralyzed muscles progress from flaccid weakness to progressive thinning and atrophy over time.
Standard Acupuncture Treatment for Traumatic Lower Paraplegia
Acupuncture for traumatic paraplegia is a core TCM rehabilitation therapy for spinal cord injury sequelae. Combined with electroacupuncture and cupping intervention, it stimulates damaged spinal nerve conduction, improves local blood circulation, relieves muscle flaccidity and atrophy, and promotes lower limb motor and neurological functional recovery.
Standard Acupoints & Needling Specification (WHO Standard)
1. Shenshu (BL23, Bilateral)
Location: 50 mm lateral to the spinous process of the 2nd lumbar vertebra (Mingmen GV4).
Needling Method: Use two 28-gauge, 3-inch filiform needles. After aseptic disinfection, insert perpendicularly 70 mm toward the interspace between the 1st and 2nd lumbar transverse processes.
Needling Sensation: Radiating numbness and distension extending to the ipsilateral lower limb.
2. Dachangshu (BL25, Bilateral)
Location: 50 mm lateral to the spinous process of the 4th lumbar vertebra (Yaoyangguan GV3).
Needling Method: Use two 30-gauge, 2.5-inch filiform needles. After routine disinfection, perform perpendicular insertion up to the 5th lumbar transverse process, reaching bony resistance.
Needling Sensation: Local lumbar distending soreness or radiating sensation toward the lower limbs.
3. Huantiao (GB30, Bilateral)
Location: At the junction of the outer one-third of the line connecting the greater trochanter of the femur and the sacral hiatus; located with the patient in a lateral recumbent and hip-flexed posture.
Needling Method: Use two 28-gauge, 4-inch filiform needles. After local disinfection, insert 95 mm toward the greater sciatic foramen.
Needling Sensation: Strong radiating soreness and numbness throughout the ipsilateral lower limb.
4. Yinmen (BL37, Bilateral)
Location: On the line connecting Chengfu (BL36) and Weizhong (BL40), approximately 150 mm inferior to Chengfu acupoint.
Needling Method: Use two 30-gauge, 3-inch filiform needles. After disinfection, insert perpendicularly 70 mm.
Needling Sensation: Local posterior thigh distension and soreness.
5. Weizhong (BL40, Bilateral)
Location: At the midpoint of the popliteal crease, between the biceps femoris and semitendinosus tendons.
Needling Method: Use two 30-gauge, 2-inch filiform needles. After aseptic disinfection, insert obliquely upward 45 mm.
Needling Sensation: Local popliteal fossa distension and soreness.
6. Chengshan (BL57, Bilateral)
Location: At the midpoint of the inverted triangle crease formed by the gastrocnemius muscle belly during ankle extension.
Needling Method: Use two 30-gauge, 2-inch filiform needles. After routine disinfection, insert perpendicularly 45 mm.
Needling Sensation: Local calf distending soreness.
Clinical Treatment Protocol
Patients maintain a prone position throughout treatment. All acupoints are needled per standard aseptic procedures, followed by electroacupuncture stimulation. Needles are retained for 40 minutes per session. After needle removal, local cupping therapy is applied for approximately 1 minute to promote blood circulation and relax muscular adhesion.
Treatment is performed once daily. A complete therapeutic course includes 10 consecutive sessions, with a 5-day rest interval before starting the next course.
Clinical Discussion & Prognostic Analysis
Standardized acupuncture rehabilitation delivers definite clinical efficacy for traumatic paraplegia. The treatment achieves optimal outcomes for patients with spinal cord compression sequelae or residual dysfunction after surgical decompression without irreversible intrinsic spinal cord destruction.
For patients with severe, complete spinal cord injury or unresolved chronic compression, acupuncture can only temporarily improve muscle tension, partially restore atrophied muscle tissue and mild neurological function. Symptoms often relapse and muscular atrophy recurs after treatment discontinuation.
The final rehabilitation prognosis depends on two core factors: the severity of spinal cord tissue damage and the adequacy of surgical decompression. Patients with mild injury and early thorough decompression obtain the best functional recovery.
During rehabilitation treatment, patients are instructed to adhere to systematic functional exercise alongside acupuncture therapy, which significantly accelerates neural remodeling and limb motor function recovery for long-term rehabilitation.
