Våpen og intervensjoner
Deltakergruppe / Arm |
Intervensjon / Behandling |
|---|---|
|
Sham-komparator: Sham comparator
Participants receive sham TI stimulation one session per day for 5 consecutive days
|
The sham TI device is the same as the active comparator's except that no current was delivered during the stimulation period.
|
|
Aktiv komparator: real TI stimulation
Participants receive real TI stimulation one session per day for 5 consecutive days
|
Stimulation was delivered as two sinusoidal alternating currents with carrier frequencies of 2000 Hz and 2010 Hz, generating a 10 Hz amplitude-modulated envelope.
Current intensity was set at 3 mA per channel.
Each session included 30-second ramp-up and ramp-down periods at the beginning and end of stimulation.

Tiltaksbeskrivelse |
Tidsramme |
|---|---|---|
|
CRS-R (Coma Recovery Scale-revised)
Tidsramme: Baseline; Within 1 week post-stimulation
|
The CRS-R scale, with scores ranging from 0 to 23, a standardized neurobehavioral assessment measure designed for use in patients with disorders of consciousness.
The scale is intended to be used to establish diagnosis, monitor behavioral recovery, predict outcome, and assess treatment effectiveness.
The CRS-R consists of 6 subscales designed to assess auditory function, receptive and expressive language, visuoperception, communication ability, motor functions, and arousal level.

Tidsramme |
|---|---|---|

EEG spectral power
Tidsramme: Baseline; Within 1 week post-stimulation
|
EEG spectral power was quantified across five canonical frequency bands: delta (1-4 Hz), theta (4-8 Hz), alpha (8-13 Hz), beta (13-30 Hz), and gamma (30-40 Hz).
Relative power spectral density (PSD) was calculated for each frequency band.
|
Baseline; Within 1 week post-stimulation
|
|
fNIRS-derived hemoglobin concentration changes
Tidsramme: fNIRS data were acquired over a 40-min session on each of the 5 treatment days.
|
Changes in oxygenated hemoglobin (ΔHbO), deoxygenated hemoglobin (ΔHbR), and total hemoglobin (ΔHbT) concentrations were measured using functional near-infrared spectroscopy (fNIRS).
|
fNIRS data were acquired over a 40-min session on each of the 5 treatment days.
|
|
GOS-E(Glasgow Outcome Scale - Extended)
Tidsramme: 6 months
|
The outcome of patients was divided into 8 grades by GOS-E, and the higher the grade, the better the prognosis.
|
6 months
|
|
Changes in CRS-R subscale scores
Tidsramme: Baseline; Within 1 week post-stimulation and at 1-month, 3-month, and 6-month follow-up.
|
The CRS-R scale, with scores ranging from 0 to 23, a standardized neurobehavioral assessment measure designed for use in patients with disorders of consciousness.
The scale is intended to be used to establish diagnosis, monitor behavioral recovery, predict outcome, and assess treatment effectiveness.
The CRS-R consists of 6 subscales designed to assess auditory function, receptive and expressive language, visuoperception, communication ability, motor functions, and arousal level.

Baseline; Within 1 week post-stimulation and at 1-month, 3-month, and 6-month follow-up.
|
|
Total CRS-R score changes at follow-up
Tidsramme: Pre-stimulation, post-stimulation and at 1-month, 3-month, and 6-month follow-up.

EEG functional connectivity
Tidsramme: Baseline; Within 1 week post-stimulation
|
EEG functional connectivity was quantified using phase-locking value (PLV) across five frequency bands: delta (1-4 Hz), theta (4-8 Hz), alpha (8-13 Hz), beta (13-30 Hz), and gamma (30-40 Hz).
|
Baseline; Within 1 week post-stimulation
|
|
Auditory steady-state response (ASSR)
Tidsramme: Baseline; Within 1 week post-stimulation
|
ASSR was recorded during EEG while participants listened to modulated tones.
ASSR strength was quantified using an amplitude-based signal-to-noise ratio (SNR), calculated as the amplitude at the target frequency divided by the mean amplitude of the surrounding spectral background.
|
Baseline; Within 1 week post-stimulation
|
|
fNIRS-derived functional connectivity
Tidsramme: fNIRS data were acquired over a 40-min session on each of the 5 treatment days.
|
Functional connectivity was estimated by calculating Pearson correlation coefficients between fNIRS time series.
|
fNIRS data were acquired over a 40-min session on each of the 5 treatment days.
