Sperimentale: tDCS
Participants receive active tDCS.
The anodal electrode is placed over the left dorsolateral prefrontal cortex (F3), and the cathodal electrode is placed over the right dorsolateral prefrontal cortex (F4).
A constant current of 2 mA is applied for 40 minutes per session, with a 30-second ramp-up and ramp-down period.
The intervention is administered once daily for 2 weeks (total of 10 sessions).

Sperimentale: alpha-tACS
Participants receive active alpha-tACS.
Two electrodes are placed over F3 and F4.
A sinusoidal alternating current at 10 Hz frequency (alpha band) is applied 1 mA (zero-to-peak) at the F3 and F4 electrodes.
Stimulation duration is 40 minutes per session, including 30-second ramp-up and ramp-down periods.
The intervention is administered once daily, 5 days per week, for 2 weeks (total of 10 sessions).

Comparatore fittizio: Sham
Sham group using the same electrode montage at F3/F4.
To maintain blinding, the stimulator delivers current only during the initial 30-second ramp-up period, followed by an immediate ramp-down, and a final 30-second ramp-up at the end of the stimulation session.
This mimics the initial sensation of active stimulation without delivering sufficient current to induce neural modulation.

Sperimentale: Exploratory Open-Label tACS Group
Participants in this exploratory arm receive the same active tACS intervention as Arm alpha-tACS, with identical stimulation parameters (e.g., 1 mA, 40 minutes, 10 Hz, targeting the bilateral dorsolateral prefrontal cortex (DLPFC)).
This arm is open-label (unblinded): participants and study personnel are aware of the treatment assignment.
It serves as a supplementary exploratory cohort to explore preliminary neural oscillation entrainment effects of tACS.
Unlike Arms 1-3, this arm is neither randomized nor blinded.
Data from this arm will be analyzed separately and are not included in the primary confirmatory hypothesis testing of the randomized controlled trial.
The overall study remains double-blind for the three-arm RCT component, with this exploratory arm conducted as an ancillary cohort.

Proportion of Participants Achieving MCID on BPI Pain Intensity Subscale
Lasso di tempo: At 1 week (mid-intervention), 2 weeks (end of intervention), and 6 weeks (follow-up) post-baseline
|
Description: The BPI is a validated self-administered questionnaire that assesses the severity of pain and its impact on daily functioning. The pain intensity subscale consists of four items rating pain at its "worst," "least," "average," and "current" (right now). Each item is rated on a 0 to 10 numeric rating scale. Higher scores mean a worse outcome. The Minimal Clinically Important Difference (MCID) is defined as a reduction of ≥ 1 point from baseline in the BPI pain intensity score. The outcome is the proportion of participants in each group who achieve this MCID threshold at each follow-up time point. |

Percentage Reduction from Baseline in HAMD-17 Total Score
Lasso di tempo: At 1 week (mid-intervention), 2 weeks (end of intervention), and 6 weeks (follow-up) post-baseline
|
The HAMD-17 is a 17-item clinician-rated scale assessing depression severity. Items are rated on 3- or 5-point scales, with total scores ranging from 0 to 52. Higher scores mean a worse outcome (greater depression severity). The outcome is the percentage reduction in HAMD-17 total score from baseline at each follow-up time point, calculated using the formula: [(Baseline score - Follow-up score) / Baseline score] × 100% A positive percentage indicates improvement (reduction in depressive symptoms). |

Change from Baseline in HAMD-17 Total Score
Lasso di tempo: At 1 week (mid-intervention), 2 weeks (post-intervention), and 6 weeks (follow-up)
|
The Hamilton Depression Rating Scale (HAMD-17) is a 17-item clinician-rated scale assessing depression severity.
Items are rated on 3- or 5-point scales, with total scores ranging from 0 to 52.
Higher scores indicate greater depression severity (worse outcome).
The outcome is the absolute change in the total score from baseline at each follow-up time point, calculated as: [(Baseline score) - (Follow-up score)].
A positive change value indicates improvement (reduction in depressive symptoms).
No pre-defined clinically meaningful threshold is applied to this continuous outcome; it is reported as the mean absolute change per group.

Change from Baseline in Pain Catastrophizing Scale (PCS) Total Score
Lasso di tempo: At 1 week (mid-intervention), 2 weeks (end of intervention), and 6 weeks (follow-up) post-baseline
|
The Pain Catastrophizing Scale (PCS) is a 13-item self-reported questionnaire.
Each item is rated on a 5-point Likert scale from 0 (not at all) to 4 (all the time), with total scores ranging from 0 to 52.
Higher scores indicate higher levels of pain catastrophizing (worse outcome).
The outcome is the absolute change in the total score from baseline at each follow-up time point, calculated as: [(Baseline score) - (Follow-up score)].
A positive change value indicates improvement (reduction in pain catastrophizing).

Change from Baseline in Generalized Anxiety Disorder Scale-7 (GAD-7) Total Score
Lasso di tempo: At 1 week (mid-intervention), 2 weeks (end of intervention), and 6 weeks (follow-up) post-baseline
|
The GAD-7 is a 7-item self-report scale (0-21, higher scores = worse outcome) assessing anxiety symptoms over the past two weeks.
The outcome is the absolute change in the total score from baseline at each follow-up time point, calculated as: [(Baseline score) - (Follow-up score)].

Change from Baseline in Clinical Global Impression (CGI) Total Score
Lasso di tempo: At 1 week (mid-intervention), 2 weeks (post-intervention), and 6 weeks (follow-up)
|
The Clinical Global Impression (CGI) scale consists of two clinician-rated subscales assessing overall treatment response: CGI-Severity (CGI-S): Rates the severity of the patient's illness on a 7-point scale from 1 (normal, not at all ill) to 7 (among the most extremely ill patients). Higher scores mean a worse outcome. CGI-Improvement (CGI-I): Rates the patient's improvement compared to baseline on a 7-point scale from 1 (very much improved) to 7 (very much worse). This subscale is only assessed at post-baseline time points. Lower scores mean a better outcome (greater improvement). The outcome is the change from baseline in CGI-S score at each follow-up time point, and the CGI-I score at each post-baseline time point. |

Change from Baseline in Resting-State Functional Connectivity of the DLPFC at 2 Weeks
Lasso di tempo: Baseline and immediately after the 2-week intervention period
|
Resting-state functional connectivity (rs-FC) of the dorsolateral prefrontal cortex (DLPFC) is assessed using resting-state functional magnetic resonance imaging (rs-fMRI).
The primary measurement is the change in seed-based functional connectivity strength between the DLPFC and its target network regions (e.g., parietal cortex, default mode network nodes), quantified as Fisher-transformed correlation coefficients (z-values) from a priori defined regions of interest.
Higher z-values indicate stronger positive functional connectivity; lower or negative values indicate weaker or anticorrelated connectivity.
Structural MRI (sMRI) is acquired for co-registration and normalization purposes.

Change from Baseline in Brain-Derived Exosome Metabolite Levels
Lasso di tempo: From baseline to post-intervention at 2 weeks
|
Metabolite profiles are measured using untargeted liquid chromatography-mass spectrometry (LC-MS) in plasma-derived brain-enriched exosomes.
Changes in metabolite profiles from baseline to post-intervention are assessed using multivariate partial least squares discriminant analysis (PLS-DA).
The primary comparison is the separation distance (e.g., Q² or R² values) between baseline and post-intervention clusters, with positive values indicating greater separation between the two time points.
This is an exploratory outcome to identify potential metabolic biomarkers and generate hypotheses related to the mechanisms of tACS/tDCS action.
Results will be reported descriptively and are not part of the primary confirmatory analysis.

Change from Baseline in Resting-State EEG Power Spectra in the Exploratory Open-Label Cohort
Lasso di tempo: Baseline, Day 1 (immediately before and after the 1st tACS session), Day 10 (immediately before and after the 10th tACS session), and Day 11 (on the day after completion of all 10 sessions)
|
Resting-state EEG is recorded for 5 minutes with eyes open and 5 minutes with eyes closed using a 64-channel EEG system.
The primary measure is the change from baseline in spectral power (absolute and relative) across frequency bands (delta: 1-4 Hz, theta: 4-8 Hz, alpha: 8-12 Hz, beta: 12-30 Hz, gamma: 30-50 Hz), with a focus on the alpha band (8-12 Hz) due to the 10 Hz tACS intervention.
Data are analyzed descriptively without formal hypothesis testing.
