Earthing as a Supportive Therapy for Post-Spinal Surgery Recovery

Background/Objectives: Spinal surgery often results in injury to the paraspinal muscles and postoperative pain, which is associated with an elevated inflammatory response and increased creatine kinase (CK) levels. Earthing, a practice involving direct or indirect contact with the Earth, facilitates the movement of electric charge between the body and the Earth, thereby stabilizing electrical potentials and influencing biochemical and bioelectrical processes. This study aimed to investigate the effects of earthing on postoperative pain and biochemical parameters. Materials and Methods: The study included an earthing group (EG) of 42 patients (18 females) who underwent spinal surgery and were earthed during nighttime postoperative rest. Blood samples were collected to measure serum concentrations of sodium, potassium, urea, glucose, C-reactive protein (CRP), alkaline phosphatase (ALP), calcium, phosphates, CK, iron, ferritin, and transferrin. These parameters were assessed on the day after surgery and the day following earthing. A control group (CG) of 42 patients (25 females) who underwent surgery for lumbar spondylosis did not receive earthing. Results: The median reduction in the EG was significantly greater than in the CG (for CK 45.0 and 20.0 U/L; for ALP 6.0 and 1.0; for transferrin 0.17 and 0.08, respectively). The median CRP difference in the EG was 0.05 mg/dL, significantly lower than in the CG, 17.2 mg/dL. The median reduction in pain intensity in VAS score was greater in the EG–2.0 compared to the CG-1.0, acknowledging a strong analgesic effect of earthing (p < 0.01). Conclusions: Earthing after spinal surgery seems to promote recovery by reducing inflammation and pain, and accelerating general healing, suggesting its potential as a supportive postoperative therapy.
