The goal of this clinical trial is to learn the effect of carbon fiber ankle foot rothosis (AFO) on dual-task walking perfromance and cognitive load for stroke patients.
The main questions it aims to answer are:

Does wearing carbon fiber AFO can improve gait and secondary task during dual task walking for individual with stroke ? Does wearing carbon fiber AFO can reduce the prefrontal load during dual task walking for individuals with stroke?
Researchers will compare gait, concurrent task performance, and FNIRs activation over prefrontal area under different test conditions (with/without AFO, single walk, cognitive dual walk, motor dual walk)
Participants will:
execute all different conditions repeatedly in a randomized order. require to visit the lab once, about 2 hours period to complete the whole experimental protocol.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Wear an off the shelf carbon fiber ankle foot orthosis(AFO).Device
Participants wore an appropriately sized off-the-shelf carbon fiber ankle-foot orthosis (AFO) during the AFO-on condition, compared with not wearing an AFO during the AFO-off condition.
Perfrom single and dual task walking.Procedure or surgery
Single-task walking was defined as walking along a 13-m pathway at a self-selected comfortable speed. Dual-task walking was defined as walking along the same pathway while concurrently performing an auditory Stroop test or holding a tray with three wooden blocks stacked on top of each other.
| Study group | Role | What they receive |
|---|---|---|
| Stroke | Experimental | Participants with subacute or chronic stroke who could walk independently without an assistive device, demonstrated normal cognitive function (Mini-Mental State Examination (MMSE) > or equal 24), and were able to comprehend instructions and respond verbally were included.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The goal of this clinical trial is to learn the effect of carbon fiber ankle foot rothosis (AFO) on dual-task walking perfromance and cognitive load for stroke patients.
The main questions it aims to answer are:
Does wearing carbon fiber AFO can improve gait and secondary task during dual task walking for individual with stroke ? Does wearing carbon fiber AFO can reduce the prefrontal load during dual task walking for individuals with stroke?
Researchers will compare gait, concurrent task performance, and FNIRs activation over prefrontal area under different test conditions (with/without AFO, single walk, cognitive dual walk, motor dual walk)
Participants will:
execute all different conditions repeatedly in a randomized order. require to visit the lab once, about 2 hours period to complete the whole experimental protocol.

Questions about this trial
What is this clinical trial studying?
A study testing Wear an off the shelf carbon fiber ankle foot orthosis(AFO). and Perfrom single and dual task walking. in people with Ankle Foot Orthosis (AFO) and Dual Task Walking, run by National Cheng-Kung University Hospital at 1 site in Taiwan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 30 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Taiwan. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
walking speed (time frame: a single experimental session (Day 1)). The study lists 7 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07500662, which also lists 22 linked publications.
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 30 Mar 2026.
