About this study
Official title: A Prospective Multicenter Cohort Study to Evaluate the Effect of Early Mobilization of Patients After Hip Fracture Fixation on Functional Outcomes in the Chinese Population
The study will assess the difference in functionality between early vs. standard mobilization after hip fracture in the Chinese population.
Read the detailed description
The primary objective of this prospective observational cohort study is to assess the difference in functionality between Group I and II (see mobilization regimens for the two groups above) at 6 weeks using the modified Barthel Index in the Chinese population.
The allocation of patients to the two groups will be performed on a clinic level: 50% of patients will be recruited by study sites in Group I (early mobilization). The other 50% of patients will be recruited by study sites in Group II. The sites are carefully selected after evaluating their standard procedures of mobilizing elderly patients after hip fractures. This process is documented using formal site selection questionnaires.
The modified Barthel Index is estimated at 75 points for Group II and at 85 points for Group I.
Patients aged 65 years and older with unstable intertrochanteric fractures (AO 31 A2 or A3) treated with an intramedullary nail will be included in this study.
The study visits will be defined as preoperative, surgery, discharge, 6 (± 2) weeks and 12 (± 2) weeks follow-up (FU) visits. Furthermore, there will be a telephone contact 12 months (± 1 month) postsurgery.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Group I | Study sites in which patients perform early mobilization as per local standard of care, which is as follows: * 2 days (at the latest) after surgery: Transfer from the bed to a sitting chair for the first time * 4 (± 2) days after surgery: Stand up and put both feet on the ground for the first time (walking aids allowed) * 5 (± 2) days after surgery: Walking (at least partial weight bearing, walking aids allowed) * The patients are instructed by the investigator at the hospital about a standardized mobilization program to be followed at home | |
| Group II | Study sites in which patients start walking (i.e. partial weight bearing, walking aids allowed) more than 7 days after surgery as per local standard of care |

The record says: finished, as of the sponsor's last update on 4 Jun 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 11 sites in China, Hong Kong. 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?
Modified Barthel Index (time frame: 6 weeks postoperative). 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 4 Jun 2020; AzTrials last refreshed its copy on 27 Oct 2026.
