Pilot Study of Exercise and Peripheral Nerve Function in People With Diabetes - ENRGy2 Addendum

September 26, 2013 updated by: Patricia Kluding, PhD, University of Kansas

Pilot Study of Exercise and Peripheral Nerve Function in People With Diabetes - Exercise and Neuropathy Research Group v.2 (ENRGy2) Addendum

This is an amendment to study posting NCT00970060. Based on preliminary results from that study is was determined there needs to be a follow-up exercise intervention study. This study has two additional aims than the original study. The objectives are to determine is a prolonged exercise routine, 16-weeks, paired with refined measures of effectiveness positively impact people with diabetic neuropathy.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
19

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

40 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Design Details

  • Allocation: N/A
  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: 16-Week Exercise Program
Subjects to participate in 16-week3 supervised aerobic exercise 3 times per week. Exercise sessions to last between 30 and 60 minutes.
Other: Aerobic Exercise
Aerobic exercises in the program include cycle ergometers, treadmills, recumbent steppers and elliptical trainers.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change nerve function
Time Frame: Baseline to Week 16
Change in nerve function will be quantified using the Total Neuropathy Score (TNS). The TNS is a composite measure of peripheral nerve function that includes grading of signs/symptoms, nerve conduction studies, and quantitative sensory testing. We will not include proprioceptive testing in this project.
Baseline to Week 16
Change in aerobic fitness
Time Frame: Baseline to Week 16
Aerobic fitness will be assessed with a graded maximal exercise test as in the previous protocol with a metabolic cart and integrated ECG.
Baseline to Week 16

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in cutaneous innervation
Time Frame: Baseline to Week 16
Change will be measured after exercise intervention to see what effects exercise has on dermal and epidermal innervation. Change measured via skin biopsy.
Baseline to Week 16
Change in maximal workload
Time Frame: Baseline to Week 16
Measured as part of the aerobic fitness assessment. Use of standardized protocol with total body recumbent stepped to be used to obtain the maximal workload.
Baseline to Week 16
Change in pain experienced
Time Frame: Baseline to Week 16
Pain will be measured using the Brief Pain Inventory Short Form for diabetic peripheral neuropathy. This scale has been specifically validated in this population and consists of 3 pain severity items and a 7-item pain interference scale.
Baseline to Week 16

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
June 1, 2012

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
