Study Stopped
The study has been temporarily halted due to a malfunction with the biofeedback equipment we are using. At present, we do not have the necessary funds to repair the equipment, and as a result, the research has been suspended for the time being.

Outcome Measures
Primary Outcomes (8)
Yale global tic severity scale
Tic symptom severity is estimated by Yale Global Tic Severity Scale Total Tic score. The YGTSS is a clinician-rated scale used to assess tic severity over the prior week. It includes a checklist of motor and vocal tics followed by an assessment of the number, frequency, intensity, complexity, and inference of motor tics and phonic tics-scored separately. Each of these dimensions is scored on a 0 to 5 scale. The YGTSS provides three tic severity scores: Total Motor (0 to 25); Total Phonic (0 to 25) and the combined Total Tic Severity Score (0 to 50), as well as a separate Impairment dimension scored from0 to 50. The Total Tic Score (YGTSS-TTS) was used in these analyses.Lower scores indicate improvement and higher scores indicate worsening.

3-month follow-up after completion of treatment (T3).
Wisconsin Card Sorting Test
The participants were asked to sort 64 cards to match either color (red, blue, yellow, or green), form (crosses, circles, triangles, or stars), or number of figures (one, two, three, four). During the task, the sorting rule changed discreetly from color to form or number of figures without the participants being informed. The participants had to shift sets accordingly and sort cards following the new sorting rule. Set shifting difficulties were indicated by preservative errors; thus, higher scores on this test represent worse performance.

Biofeedback therapy
EXPERIMENTALthree times a week, every other day interval, 30 minutes each time, each subject received 20 biofeedback training (using the Infiniti3000A biofeedback system Patients in the theta group decreased the theta amplitude at Cz. Patients in the theta group received positive feedback when their theta activity was below the feedback threshold.
Drug therapy
ACTIVE COMPARATORConsidering the patients with chronic tic disorder (chronic motor or vocal tic disorder or Tourette's disorder), aripiprazole was selected as a single drug with constant dose during the treatment. In case of extrapyramidal side effects, benhexol was given to reduce the extrapyramidal side effects, and the dosage and duration of medication were recorded
