About this study

Isokinetic muscle strength test implemented by the Biodex system is a method used for evaluating muscle function that has been applied clinically in the field of sports and rehabilitation medicine. However, information on its application on Haglund's deformity remain insufficient. Therefore, the present study is designed to examine the effectiveness of the muscle strength test using the Biodex system in evaluating the recovery of athletic capacity in patients with Haglund's deformity following endoscopic surgery.

Read the detailed description

Patients. A retrospective (medical records), level 3 evidence study was designed to evaluate the outcomes of patients who underwent endoscopic surgery for Haglund's deformity. The present study was approved by the Peking University Third Hospital's ethics committee. Written informed consent was obtained from all patients, parents or guardians of the patients prior to the present study. The rights of the patients were protected.

Diagnosis. Patients were designed to be diagnosed based on subjective complaints, combined with clinical and radiological examinations. Radiological measurements for this disease include the Fowler-Phillip angle, calcaneal pith angle, parallel pitch lines, Chauveaux-Liet angle and the X/Y ratio.

What is being measured

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

  1. Biodex results on both sides before surgery

    Biodex isokinetic muscle testing system was applied in this research. Isokinetic muscle strength test is a kind of muscle function evaluation and test method, which has been applied in the research and clinical work of sports medicine and rehabilitation medicine but never on Haglund's disease before. The isokinetic muscle strength test of the flexor and dorsiflexion of the ankle joint can evaluate the muscle strength and endurance to reflect the postoperative patient's capacity for action, providing reliable clinical evidence for postoperative rehabilitation of patients after endoscopic calcaneoplasties. Isokinetic strength test conducted on both the injured and uninjured sides of the patients using the Biodex system before surgery.

    Measured: pre-surgery

  2. Biodex results on both sides at 3 months

    Isokinetic strength test conducted on both the injured and uninjured sides of the patients using the Biodex system 3 months after surgery.

    Measured: 3 months after surgery

  3. Biodex results on both sides at 6 months

    Isokinetic strength test conducted on both the injured and uninjured sides of the patients using the Biodex system 6 months after surgery.

    Measured: 6 months after surgery

Questions about this trial

What is this clinical trial studying?

An observational study of Haglund's Deformity, 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 1 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 15 Jul 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 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?

Biodex results on both sides before surgery (time frame: pre-surgery). The study lists 3 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 15 Jul 2020.
