%X Chronic pain, a multidimensional experience affecting individuals¡¯
sensory, cognitive, and emotional aspects, significantly impacts their quality
of life. Post-laminectomy syndrome, a condition characterized by persistent
back pain following spinal surgery, often
leads to disability and increased healthcare utilization. Methods: This
randomized, controlled, blind clinical trial aimed to investigate the efficacy
of Transcranial Direct Current Stimulation (tDCS) in managing pain from
post-laminectomy syndrome in patients. Twenty-four participants were assigned
to three groups: sham stimulation, active stimulation over primary motor cortex
(M1), or stimulation over dorsolateral prefrontal cortex (DLPFC). Stimulation
was administered for five consecutive days, 20 minutes per session, using a
current of 1.5 mA through 25 cm2 electrodes. Pain intensity was assessed using Visual Analog Scale (VAS)
before, during, and after intervention. Results: An ANOVA model demonstrates significant reduction in
pain intensity compared to baseline in VAS, (F(7, 285) = 12.292; p < 0.001; Power = 1.000; ¦Ç2p = 0.534),
in tDCS applied to M1, after five days of intervention. After stimulation, a
significant improvement was observed in WHOQoL-Bref Quality of life item 1 (p = 0
