About this study

Official title: Development of a Smartphone-based System for Training Subjects With Chronic Ankle Instability and Training Effect Evaluation

This study aims to verify the training effect of smartphone-based training for chronic ankle instability(CAI) subjects. By randomizing subjects to App training group, clinical training group and control group, the training effect will be compared among groups.

Read the detailed description

Postural control ability may be damaged after ankle sprains. Poor postural control ability is the risk factors of the ankle sprain, forming a vicious circle of recurrent sprains. Proper and early assessment is the key to breaking down the circle. Smartphones have been utilized in the medical field. With built-in sensors, utilizing smartphones as assessment tools can provide quantitative data of postural control performance. This study aims to verify the training effect of smartphone-based training for CAI subjects.

CAI subjects were recruited and randomly assigned to App training group, Home training group and control group, receiving 6 weeks of intervention. Pre-test was conducted before the intervention, and the post-test was conducted after the 6-week intervention. The follow up assessment was conducted 4 weeks after the post-test.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Postural sway measurement

    Using smartphone application and force plate to record the postural sway during single leg stance.

    Measured: 30 seconds

  2. Star Excursion Balance Test

    To assess the dynamic balance ability of subjects.

    Measured: 5 minutes

Secondary outcomes (2)
  1. Foot and Ankle Outcome Score

    An ankle function assessment tool, with 5 dimensions includes symptoms, pain, activity, function and sport, and quality of life.

    The scale score ranges from 0% to 100%, the higher the percentage, the better ankle function. Subjects answer the questions by choosing different choices that describe their condition the best.

    The total score will be summed up and calculated as percentage.

    Measured: 5 minutes

  2. Foot and Ankle Ability Measure-sport subscale

    An ankle function assessment tool. The scale score ranges from 0% to 100%, the higher the percentage, the better ankle function. Subjects answer the 7 questions by choosing different degree of difficulty to accomplish the activities.

    The total score will be summed up and calculated as percentage.

    Measured: 5 minutes

Questions about this trial

What is this clinical trial studying?

A study testing App Balance training and Home Balance training in people with Chronic Ankle Instability, run by National Yang Ming Chiao Tung University 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 7 inclusion and 5 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 17 Feb 2020. 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?

Postural sway measurement (time frame: 30 seconds). The study lists 2 primary outcomes in all. 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 17 Feb 2020.
