Trial summary

Background: Primary lateral sclerosis (PLS) is a rare disease. It leads to weakness in the muscle of the arms, legs, and face. People with PLS develop muscle stiffness called spasticity. Researchers want to find a better way to measure this. Read more about this study

About this study

Official title: A Pilot Study of Muscle Ultrasound Measures as Biomarkers of Upper Motor Neuron Function

Background:

  • Primary lateral sclerosis (PLS) is a rare disease. It leads to weakness in the muscle of the arms, legs, and face. People with PLS develop muscle stiffness called spasticity. Researchers want to find a better way to measure this. They want to see if ultrasound, which uses sound waves to look at parts of the body, can measure spasticity and stiffness in muscles.

Objective:

  • To see if ultrasound can detect and measure muscle spasticity in people with PLS.

Eligibility:

  • People ages 18 75 who have a diagnosis of PLS and are enrolled in protocol 01-N-0145.
  • Healthy volunteers ages 18 75.

Design:

  • Participants with PLS will have 1 study visit. Healthy participants will have upto 5 visits. Each visit will be about 2 hours.
  • Participants will have tests of muscle strength. They will be examined. They will push their arms and legs against researchers in different positions.
  • Participants will have tests of muscle stiffness. Their arms and legs will be moved while they relax.
  • Participants will have a muscle ultrasound test. They will lie on a table. Gel will be placed on the skin over the muscles of the arms and legs. A probe, like a microphone, will be moved over the skin. Researchers will look at several muscles.
  • Participants should try to stay still during the ultrasound. It may be done several times and may be done by different examiners.

Objective

Persons with corticospinal, or upper motor neuron dysfunction have increased muscle stiffness from spasticity. Spasticity is established by clinical examination, but there are few reliable objective measures of spasticity. New ultrasound techniques to measure the elastic properties of tissue represent a potential measure of spasticity. The ultrasound measures of tissue elasticity are painless and quick to perform, but their ability to detect changes resulting from spasticity is uncertain. The goal of this pilot study is to see how much ultrasound measures of muscle elasticity differ between patients with spasticity and healthy controls. Secondary objectives are to correlate muscle elasticity measures with a clinical rating scale of spasticity and to assess intra and inter-rater reliability. This is a protocol for primary lateral sclerosis (PLS) patients who are enrolled in another NIH study in which they have been diagnosed with spasticity.

Study Population

23 adult PLS patients with arm or leg spasticity currently enrolled in an NIH protocol

30 healthy adult controls with normal neurological exams.

Design

The first phase, an investigator training phase, is aimed to become familiar with the Siemens Acuson S2000 after the upgrade. The two investigators will train with 5 healthy volunteers. In the second phase inter-observer variability of the ultrasound and Ashworth scale will be assessed by having healthy volunteers and patients evaluated by the different investigators. Since spasticity does fluctuate throughout the day, subjects will be consecutively assessed for inter-observer variability and within a few hours or around the same time the following day (depending on patient availability) for intra-observer variability. Each investigator will do the Ashworth scale independent of the other. Each investigator will do the ultrasound independent of the other. In the third phase, we will assess patients and volunteers to reach the sample size that a power analysis suggested that we would need to measure differences between patients with spasticity and controls.

Outcome Measures

The primary outcome will be measuring muscle stiffness from the biceps brachii using ultrasound elastography, which will be compared between patient groups and control groups. A secondary outcome will be the correlation of muscle stiffness at rest with the modified Ashworth score for elbow flexion. Measures of muscle strength and ultrasound measures of density and thickness will be examined in an exploratory fashion. Elastography of the tibialis anterior will be examined in an exploratory fashion.

Questions about this trial

What is this clinical trial studying?

An observational study of Muscle Spasticity, run by National Institute of Neurological Disorders and Stroke (NINDS) 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 10 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 17 Dec 2019. 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?

The primary outcome will be measuring muscle stiffness from the biceps brachii using ultrasound elastography, which will be compared between patient groups and control groups. (time frame: 2 years). 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 Dec 2019.
