About this study
Official title: Difference of Plantar Pressure Distribution Between Surgical Treatment and Conservative Treatment for Chronic Ankle Instability
The objective of this study was to compare the difference of plantar pressure distribution between surgical treatment and conservative treatment for CAI.
Read the detailed description
The data of 20 patients who underwent surgery after reconstruction of the lateral collateral ligament of the ankle joint and 20 patients who underwent balance rehabilitation training were analyzed to compare the clinical effects of surgical treatment and conservative treatment for chronic ankle instability, in order to better guide the selection of the optimal intervention program for patients with chronic ankle joint.

Questions about this trial
What is this clinical trial studying?
An observational study of Chronic Ankle Instability, run by Peking University Third Hospital at 1 site in China.
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 2 inclusion and 1 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 14 Jul 2021. 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 China. 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?
FAAM (time frame: pre-surgery, one year after sugery). 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 14 Jul 2021; AzTrials last refreshed its copy on 7 Nov 2026.
