About this study

This project proposes a longitudinal design that uses multinuclear-MRI to evaluate the mechanistic effects of exercise on skeletal muscle function and peripheral nerve integrity in patients with diabetic peripheral neuropathy (DPN), and to determine whether exercise can reverse DPN symptoms. The investigators will prescribe a 10-week exercise program to 40 DPN patients. The investigators will acquire multinuclear-MRI data before and after the intervention that can provide mechanistic insight into the adaptations in lower leg muscle function and peripheral nerve integrity of patients with DPN, and their role in improving DPN symptoms following physical exercise intervention.

What participants receive

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

  • Exercise ProgramProcedure or surgery

    The exercise program will combine moderate intensity aerobic exercise with lower-extremity specific resistance training. A moderate level of intensity will be calculated based on results from a maximal graded exercise test (VO2R) conducted prior to the intervention.

Study groups in NCT03686423
Study groupRoleWhat they receive
Patients with Type 2 Diabetes and Clinical Symptoms of DPNExperimentalPatients will be individually prescribed to a 10-week exercise program with both aerobic and resistance components. Prior to beginning the intervention, patients will participate in a maximal graded exercise test (VO2R) using a cycle ergometer with a metabolic cart and integrated ECG.

What is being measured

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

  1. Body Mass Index (BMI)

    The BMI calculation divides an adult's weight in kilograms by their height in meters squared.

    Measured: Baseline

  2. Change From Baseline in Body Mass Index (BMI)

    The BMI calculation divides an adult's weight in kilograms by their height in meters squared.

    Measured: Week 10

  3. Glycosylated Hemoglobin (HbA1c)

    The glycosylated hemoglobin test shows what a person's average blood glucose level was for the 2 to 3 months before the test. Measured via patient blood samples.

    Measured: Baseline

  4. Glycosylated Hemoglobin (HbA1c)

    The glycosylated hemoglobin test shows what a person's average blood glucose level was for the 2 to 3 months before the test. Measured via patient blood samples.

  7. Michigan Neuropathy Screening Instrument (MNSI) Symptom Questionnaire

    15-question assessment of symptoms. Responses of "yes" to items 1-3, 5-6, 8-9, 11-12, 14-15 are each counted as one point. A "no" response on items 7 and 13 counts as 1 point. Item 4 is a measure of impaired circulation and item 10 is a measure of general asthenia; neither are included in scoring. The total score ranges from 0-13; lower scores indicate less prevalent symptoms; a decrease in scores indicates symptoms decreased during the observational period.

  21. Fractional Anisotropy (FA) in the Tibial Nerve

    FA is a scalar value between zero and one that describes the degree of anisotropy of a diffusion process. A value of zero means that diffusion is isotropic, i.e. it is unrestricted (or equally restricted) in all directions. A value of one means that diffusion occurs only along one axis and is fully restricted along all other directions. Measured using Diffusion Tensor Imaging (DTI).

    Measured: Baseline

  22. Fractional Anisotropy (FA) in the Tibial Nerve

    FA is a scalar value between zero and one that describes the degree of anisotropy of a diffusion process. A value of zero means that diffusion is isotropic, i.e. it is unrestricted (or equally restricted) in all directions. A value of one means that diffusion occurs only along one axis and is fully restricted along all other directions. Measured using Diffusion Tensor Imaging (DTI).

  23. Apparent Diffusion Coefficient (ADC) in the Tibial Nerve

    ADC is a measure of the magnitude of diffusion (of water molecules) within tissue. Measured using DTI.

Questions about this trial

What is this clinical trial studying?

A study testing Exercise Program in people with Peripheral Neuropathy and Diabetes, run by NYU Langone Health 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 5 inclusion and 10 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 17 May 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?

Yes. Results are posted in the registry (first posted 17 May 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Body Mass Index (BMI) (time frame: Baseline). The study lists 24 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 17 May 2023; AzTrials last refreshed its copy on 31 Oct 2026.
