About this study
This is a double blinded, randomized control trial with a pretest-posttest control and interventional groups design. Both the assessor and participants are blinded to all assessments and evaluations. All patients with subacute stroke undergo in-patient or out-patient rehabilitation are screened initially by a series of screening test. Suitable patients are assigned randomly to 3 groups respectively. Group 1 is the combined transcranial direct current stimulation (tDCS) and neurofeedback group. Group 2 is the neurofeedback group. Group 3 is the control group with sham neurofeedback training.
Read the detailed description
Treatment sessions for all three groups are conducted by the investigators who has training in neurofeedback and transcranial direct current stimulation (tDCs). Each participant performed 10 training sessions on different days. Sessions were conducted 3-5 times a week The tDCS + neurofeedback group will carry out 30 minutes tDCS and 30 minutes neurofeedback training.
The real neurofeedback group will carry out 30 minutes neurofeedback training. The sham neurofeedback group will conduct the 30 minutes sham neurofeedback training.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change score in Trail Making Test A & B from baseline
Trail Making Test is a neuropsychological test of visual attention and task switching. It consists of two parts in which the subject is instructed to connect a set of 25 dots as quickly as possible while still maintaining accuracy.
Measured: One day before the treatment , up to 4 weeks, up to 16 weeks
Secondary outcomes (2)
Change score in Functional Independence Measure (FIM) from baseline
The Functional Independence Measure instrument is a basic indicator of patient disability. FIM is used to track the changes in the functional ability of a patient during an episode of hospital rehabilitation care.
Measured: One day before the treatment , up to 4 weeks, up to 16 weeks
Change score in Stroke Adapted 30 item version of the Sickness Impact Profile (SA - SIP 30)
SA-SIP 30 assesses quality of life in patients who have sustained a stroke.
Measured: One day before the treatment , up to 4 weeks, up to 16 weeks

Where is the study taking place?
The record lists 1 site in Hong Kong. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change score in Trail Making Test A & B from baseline (time frame: One day before the treatment , up to 4 weeks, up to 16 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Mar 2024; AzTrials last refreshed its copy on 8 Nov 2026.
