About this study
Official title: Weight-bearing Training Exercise May Improve Loading of Trans-tibial Prosthesis and Functional Gait
A simple weight-bearing exercise has been designed using off-the-shelves devices (Nintendo Wii Balance Board) and centre of pressure (COP) analysis software (Python) for trans-tibial amputees receiving their first prosthesis. A pilot randomised control study will be conducted to check the progress with weight-bearing training using COP-based objective measures. Additionally, gait and functional task performance will be assessed by means of clinical test. Participants will be divided into 2 groups: test group (performing additional weight-bearing exercises) and control group (receiving only conventional training for fitting of initial prosthesis).
Read the detailed description
Each patient meeting the inclusion criteria will be randomised to either the test group or the control group. The patients will perform ten training sessions with the initial prosthesis, each session lasting for about 30 minutes, within the period of two weeks. They will be assessed at baseline and after the training program.

Questions about this trial
What is this clinical trial studying?
A study testing additional weight-bearing exercise and standard weight-bearing exercise in people with Amputation, run by University Rehabilitation Institute, Republic of Slovenia at 1 site in Slovenia.
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 2 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 27 Jan 2022. 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 Slovenia. 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?
Change in centre of pressure (COP) from baseline (time frame: Assessment at baseline and after two weeks). 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 27 Jan 2022; AzTrials last refreshed its copy on 6 Nov 2026.
