About this study

The purpose of this study is to determine if there are differences in balance, strength, functional performance and self-reported outcomes for subjects with knee osteoarthritis who complete a low intensity, long duration eccentric training program compared to those who complete a high intensity, short duration eccentric training program. This study will be utilizing the Eccentron (manufactured by BTE Technologies) for the performance of all eccentric exercise.

Read the detailed description

Arthritis is the leading cause of disability in the United States. Osteoarthritis (OA) is the most common type of arthritis and affects nearly 27 million Americans. Knee OA is the most common type of osteoarthritis and is estimated to affect 42.1% of women and 31.2% of men over the age of 60.

Osteoarthritis is most likely multi-factorial with several underlying causes. It is no longer considered "a degenerative joint disease" but rather a process that involves dynamic biomechanical, biochemical, and cellular processes. It not only involves degeneration of the articular cartilage, but also inflammation of the synovium, changes to the underlying subchondral bone, and the development of osteophytes. Currently, it appears that numerous systemic factors can lead to the initiation of OA through different causal pathways . These systemic causes can then be amplified by local factors such as trauma or increased loading caused by obesity.

Currently, there is no "cure" for OA and attempts to find a disease modifying drug have been unsuccessful. Thus, treatment currently focuses on mitigating factors that are known to affect the radiographic progression of the disease as well as lead to activity limitation and participation restriction.9,10 Decreases in lower extremity strength are a major cause of activity limitations given the vital role of strength in activities of daily living.

One method that is used to mitigate progressing factors is through the use of an exercise program. Many types of exercise have been used successfully in the literature including resistance training. Resistance training can take many different forms such as isometric, isotonic (concentric and/or eccentric) or isokinetic with various intensities. Presently, there is little evidence for the use of eccentric training interventions for patients with knee OA. This study aims to further examine this type of resistance training for the OA population. Therefore, the purpose of this study is to examine the effects of low intensity, long duration eccentric resistance training and high intensity, short duration eccentric resistance training in individuals with knee OA. Ideally, this study will allow us to determine the overall effects of eccentric resistance training as well as the potential differences of the two types of eccentric resistance training.

What participants receive

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

  • High Intensity Short Duration ExerciseProcedure or surgery

    Participants randomized to this group will perform 4 sets of 8-15 repetitions of eccentric exercise using the Eccentron set at 50-80% of the participant's one repetition maximum.

  • Low intensity Long Duration ExerciseProcedure or surgery

    Participants randomized to this group will perform 5-20 minutes of continuous eccentric exercise using the Eccentron set at 50% of the participant's one repetition maximum.

What is being measured

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

  1. Isometric quadriceps strength as measured by a hand held dynamometer

    The primary outcome for this study is the change in quadriceps strength from baseline to 8 weeks (end of intervention) in both experimental groups.

    Measured: Change from baseline to 8 weeks

Secondary outcomes (7)
  1. Lower extremity muscle strength as measured by a hand held dynamometer

    Trunk flexion/extension, Hip Abduction/Extension, Knee Flexion/Extension, and Ankle Plantarflexion and Dorsiflexion will be assessed at baseline and 8 weeks by a hand held dynamometer.

    Measured: Change from baseline to 8 weeks

  2. Timed Up and Go Test

    Measured: Change from baseline to 8 weeks

  3. 6-minute Walk Test

    Measured: Change from baseline to 8 weeks

  4. Five times sit to stand test

    Measured: Change from baseline to 8 weeks

  5. Balance (assessed utilizing the romberg, sharpened romberg, one-legged stance test, functional reach test, and step test)

    Balance will be assessed utilizing the romberg, sharpened romberg, one-legged stance test, functional reach test, and step test.

    Measured: Change from baseline to 8 weeks

  6. Arthritis Impact Measurement Scale (AIMS)

    Measured: Change from baseline to 8 weeks

  7. Pain and muscle soreness ( assessed utilizing a numeric pain rating scale)

    Pain and muscle soreness will be assessed utilizing a numeric pain rating scale at the beginning and end of every treatment session.

    Measured: At the beginning of every treatment session and following every treatment session for the 8 week intervention

Questions about this trial

What is this clinical trial studying?

A study testing High Intensity Short Duration Exercise and Low intensity Long Duration Exercise in people with Osteoarthritis, run by Regis 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 6 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 26 Feb 2016. 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?

Isometric quadriceps strength as measured by a hand held dynamometer (time frame: Change from baseline to 8 weeks). 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 26 Feb 2016.
