Trial summary

Following orthopedic surgery and/or injury, a significant loss of muscle mass is generally observed. While this loss of muscle mass appears to be the norm, it causes significant problems in both the athletic and general population. Read more about this study

About this study

Following orthopedic surgery and/or injury, a significant loss of muscle mass is generally observed. While this loss of muscle mass appears to be the norm, it causes significant problems in both the athletic and general population. Athletes struggle to regain their performance because of the decrease in muscle mass and also have a greater potential for reinjury while they are in a depleted state. In the general population, and particularly among the elderly, this loss in muscle mass can be even more devastating because as people age, it is more difficult to regain muscle after it is lost. In elderly individuals, this loss in muscle mass can lead to significant disability, diminished quality of life along with an increased risk of falls. In addition to the muscle mass lost during the post-operative period, the strength of the muscle also decreases. This has obvious performance implications in athletes, as well as having the potential to extend recovery time. In the elderly, decreased strength may result in reduced independence and inability to perform activities of daily living. Many previous bed rest studies have reported that significant bone loss also occurs during times of decreased mechanical loading. The post-operative period generally results in decreased mechanical loading; however, some muscle loading will still occur during the rehabilitation process. The dynamic relation between muscle activity/loading and bone density changes in the post-operative state has not been fully described and requires further study.

With this knowledge of the importance of nutrition to the musculoskeletal system, applying the principles of increased protein intake through the addition of a dietary supplement to a population preparing for orthopedic surgery and subsequent muscle disuse is a logical next step. The investigators hypothesize that through the consumption of a protein-based dietary supplement three times per day (75g protein), along with educating patients on the importance of consuming foods that are high in protein, there will be an attenuation of decreases in muscle mass and strength as well as losses in bone that occur with orthopedic injury and disuse. The investigators long-term goal is to identify a nutritional protocol that can be implemented prior to and following orthopedic surgery to diminish the deleterious effects of the subsequent disuse on muscle and bone.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Profile PerformDietary supplement

    The dietary supplement includes 1.5 grams of fat, 19 grams of carbohydrate, and 25 grams of protein per serving. Participants in the experimental group will consume 3 servings per day.

  • Lower Limb SuspensionOther

    This group will complete two weeks of lower limb suspension.

What is being measured

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

  1. Muscle Mass

    Whole body muscle mass (kg) will be measured using DXA while muscle cross-sectional area of the lower leg will be measured via pQCT

    Measured: Measurements will be obtained prior to immediately following 2 weeks of lower limb suspension

Secondary outcomes (1)
  1. Muscle strength

    Torque production (NM) will be measured using isokinetic testing with a Biodex System 4 Ergometer. The protocol will include maximal quadricep extension and hamstring flexion performed at 60, 180, and 300 degrees per second

    Measured: Measurements will be obtained prior to immediately following 2 weeks of lower limb suspension

Questions about this trial

What is this clinical trial studying?

A study testing Profile Perform and Lower Limb Suspension in people with Disuse Atrophy, run by South Dakota State University at 1 site in United States.

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 8 Feb 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 United States. 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?

Muscle Mass (time frame: Measurements will be obtained prior to immediately following 2 weeks of lower limb suspension). 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 8 Feb 2023.
