About this study

Official title: Could Contralateral Quadriceps Strength Training Attenuate the Strength Loss in the ACL-operated Knee?

The main aims of the study are (1) to examine the impact of contralateral strength training on the quadriceps muscle function after ACL surgery and (2) to compare the magnitude of cross-education induced by NMES versus eccentric strength training.

Being tested
Neuromuscular electrical stimulation, eccentric training

Receives: Behavioral: Neuromuscular electrical stimulation

What is being measured

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

  1. Change in bilateral quadriceps muscle strength [Nm]

    Measured: 1-2weeks preoperative/ 2weeks/ 8weeks/ 6month

  2. Change in quadriceps muscle activation

    Measured: 1-2 weeks preoperative/ 2weeks/ 8weeks/ 6month

Secondary outcomes (3)
  1. Change in muscle architecture

    Measured: 1-2 weeks preoperative/ 2weeks/ 8weeks/ 6month

  2. Change in self-reported questionnaire outcomes (KOOS, WOMAClk)

    Measured: 1-2weeks preoperative/ 2weeks/ 8weeks/ 6 month

  3. functional test outcomes

    Assessment of present functional status by means of hop tests

    Measured: 6month postop

Questions about this trial

What is this clinical trial studying?

A study testing Neuromuscular electrical stimulation and eccentric training in people with Muscle Weakness After Anterior Cruciate Ligament Reconstruction, run by Schulthess Klinik at 1 site in Switzerland.

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 4 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 19 Dec 2023. 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 Switzerland. 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. Some participants in this study may receive a placebo. 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 bilateral quadriceps muscle strength [Nm] (time frame: 1-2weeks preoperative/ 2weeks/ 8weeks/ 6month). 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?

On the ClinicalTrials.gov record for NCT01901965, which also lists 2 linked publications.

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 19 Dec 2023.
