About this study

Official title: Effects of Exercise Using Electrical Muscle Stimulation in End Stage Kidney Disease

The investigators propose a pilot feasibility study to determine if exercise delivered by passive electrical muscle stimulation (EMS) in patients with end stage renal disease (ESRD) on hemodialysis improves physical fitness and insulin resistance, outcome markers associated with morbidity and mortality in this population.

Read the detailed description

Subjects who enroll and meet the inclusion and none of the exclusion criteria will first undergo baseline testing including recording of demographic, medical, dialysis and exercise history, taking surveys to assess quality of life and overall mood, measurement of vital signs and anthropomorphic measurements (height, weight, thigh circumference), have blood collected to assess insulin resistance and cytokine levels, measurement of distance walked in 6 minutes and testing of thigh muscle strength.

Subjects will then undergo a 1 month observation period to monitor and optimize their dialysis treatment.

After 1 month the subjects will undergo a repeat assessment of all the baseline testing. They will also undergo a standardized exercise stress test and measurement of body fat and lean body mass with a dual-energy x-ray absorptiometry (DXA) scan.

Subjects then initiate passive electrical muscle stimulation (EMS) delivered by a commercially available FDA approved neuromuscular stimulator ("EMPI 300PV" or its replacement, EMPI Continuum device obtained from EMPI, Inc., St Paul MN) 3 times a week to the quadriceps muscle groups (15 minutes on each side, 30 minutes total) while on hemodialysis. The duration of training will last for 4 months. Subjects will be monitored at regular intervals during the training to make sure they are doing the training correctly and they are not experiencing any problems.

At 2 and 4 months the subjects will undergo again have repeat assessment of the baseline testing as well as undergoing the standardized exercise stress test and a DXA scan.

At 4 months the subjects will all stop the passive exercise training and then will be followed up 1 month later to repeat assessment of all the baseline testing but will not undergoing the standardized exercise stress test and a DXA scan.

For subjects who agree the investigators will also perform a muscle biopsy under local anesthesia before and 4 hours after the first exercise training session and again at 2 and 4 months. This is used to measure messenger RNA response (gene expression testing) to tell what genes are activated during training.

The efficacy of the exercise training will be assessed by change in aerobic capacity measured by maximal oxygen consumption (peak VO2) and quadriceps muscle strength measured

The primary outcome measure will be whether exercise training improves measures of insulin resistance The investigators will also assess whether there is improvement in other inflammatory and oxidative stress cytokines in the blood stream and whether the training improved their physical performance or overall quality of life.

The total duration of the study for any patient is expected to be 6 months.

What is being measured

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

  1. Quadriceps Muscle Strength Measured by a Belt-stabilized Portable Dynamometer

    Muscle strength was measured using a belt-stabilized hand held dynamometer (BSHHD) using a validated technique. Briefly, isometric knee extension strength (torque) was measured with patients seated on an elevated chair and their knees bent at about 90o of flexion (i.e., the legs hanging vertical). Patients are stabilized to the chair with straps around proximal thighs and waist. A dynamometer-stabilizing belt is passed around a bar secured behind the back legs of the chair and over a calibrated hand-held dynamometer that was placed against the anterior leg of the patient just proximal to the malleoli. The patient is asked to perform three leg extensions with the leg separated by 30 seconds of rest. The first effort is sub-maximal to get the patient accustom to the procedure. Then two full strength efforts are performed and used for calculation of average peak force (newtons, N) generated. The test is performed sequentially on both legs at each measurement session.

    Measured: Baseline, Start EMS, 2 months and 4 months of EMS training, and 1 month post exercise

Secondary outcomes (1)
  1. Leg Composition by Dual Energy X-ray Absorptiometry (DXA).

    Advanced body composition analysis will be performed by DXA scan to measure regional fat and lean mass before starting EMS training and again after 2 and 4 months of EMS training. Specific areas of interest will be in determining whether EMS training produces the expected changes in thigh fat and muscle mass. The test is performed in the CRU at the University of Iowa using a Discovery A DXA scanner with the latest software version package (Hologic Inc., Bedford, MA). The advanced body composition analysis software package measures total regional body composition (cm2) using a validated technique that produces comparable results to a CT scan with less cost and radiation exposure.The total radiation dose is less than one tenth that of a standard CXR and equivalent to one-day exposure to natural background radiation. Patients will be asked to report to the CRU dressed metal-free (no zippers, jewelry, piercings, underwire bra, etc.). Each study will take approximately 30 minutes.

    Measured: Baseline, 2 and 4 months of EMS training

Questions about this trial

What is this clinical trial studying?

A study testing EMS users in ESRD in people with Dialysis, run by University of Iowa 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 2 inclusion and 8 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: stopped early, as of the sponsor's last update on 8 Jan 2025. 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 8 Jan 2025). 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?

Quadriceps Muscle Strength Measured by a Belt-stabilized Portable Dynamometer (time frame: Baseline, Start EMS, 2 months and 4 months of EMS training, and 1 month post exercise). 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 Jan 2025.
