Electroacupuncture Restores Movement After Spinal Cord Injury

A new study published in Burns & Trauma demonstrates that electroacupuncture can interrupt the destructive cascade of secondary damage following spinal cord injury. By targeting the PKCδ–TRPA1 signaling pathway, electroacupuncture reduces calcium overload, suppresses stress signals within neurons, and prevents cell death. The treatment also enhances nerve regeneration and motor coordination, offering a promising non-pharmacological strategy for restoring movement after spinal cord trauma.

Why it matters

Spinal cord injury is a leading cause of long-term disability, with current treatments offering limited protection against the delayed cellular events that drive lasting neurological impairment. Therapies capable of modulating calcium signaling and reducing neuronal stress are urgently needed to promote neural recovery.

The details

The study found that spinal cord injury activates the PKCδ–TRPA1 signaling pathway, leading to uncontrolled calcium influx that overwhelms neurons and triggers stress responses and apoptosis. Electroacupuncture treatment markedly suppressed this pathway, reducing calcium overload and dampening stress-related proteins linked to neuronal death. Treated mice showed enhanced hindlimb coordination, stronger muscle activation, and higher locomotor scores. Electroacupuncture also boosted neurotrophic factors, promoted new neuron generation, and facilitated axonal regeneration, translating into measurable recovery of motor function.

• The study was published in January 2025 in the journal Burns & Trauma.
• The research was conducted by a team from Wenzhou Medical University.

What’s next

The researchers emphasize that further clinical validation is required, but targeting stress-related calcium pathways may complement existing rehabilitation strategies and inspire new integrative treatment protocols for spinal cord injury.
