About this study

Official title: Closed Loop Control of Vibration for Muscular Spasms After Human Spinal Cord Injury: Efficacy and Mechanism

This study uses closed-loop control of tendon vibration to implement clinically meaningful management of muscle spasms after spinal cord injury (SCI), and to understand the mechanisms responsible for spasm generation change in response to vibration.

Read the detailed description

The specific aims of this study are listed below:

1a) Evaluate the ergonomics of the wearable device that will be used to record and detect spasms, then to deliver vibration to tendons to dampen spasms.

  1. b) Determine the vibration parameters that best reduce spasms in leg muscles paralyzed by spinal cord injury (SCI) in the laboratory using the wearable device.
  2. a) Examine the efficacy of tendon vibration in altering muscle spasms by treating spasms as they occur in real world environments using 24-hour electromyographic (EMG) recordings.

Hypothesis 2a: Achilles tendon vibration will dampen spasms acutely, and may alter their distribution Assess excitatory and/or inhibitory mechanisms that underlie spasms, and changes induced with vibration, by recording physiological, clinical, functional and self-reported measures of different aspects of spasticity, and health-related quality of life, before and after conditioning spasms with vibration. These data will provide insight into the site(s), magnitude, and time-course of changes with vibration; and user perspective on the effects of the therapy.

Achilles tendon vibration will dampen spasms by reconfiguring circuits generating 6-13 Hz shared drive to motoneurons.

What participants receive

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

Receives: Device: Wearable EMG/Vibration device
Spinal Cord Injury GroupActive comparator1a. A focus group to gather information about the perceptions, opinions, beliefs, and attitudes towards management of muscle spasms by vibration using our portable device, information that will drive design improvement (size, fit, weight). 1b. In the lab, we will trigger spasms in paralyzed leg muscles in one of two common postures (seated, reclined), detect the contractions using electromyography (EMG), and condition alternate spasms with vibration using our custom device. We will examine the vibration parameters that reduce muscle spasms best. 2. Participants will complete 1 or 2 multi-day experiments. EMG (24-hour) data will be collected at baseline (day 1), during the vibration intervention (day 2), and post intervention (day 3) to examine the acute effects of vibration on muscle spasms
Receives: Device: Wearable EMG/Vibration device

What is being measured

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

  1. Changes in muscle spasms with vibration device

    Measured by records of EMG from 4 muscles to quantify spasms

    Measured: 4 weeks

Secondary outcomes (1)
  1. Questionnaire

    Quantitative and qualitative survey for subjects developed to evaluate comfort and user-friendliness of device. The questionnaire includes 11-point scale questions to rate spasms and effect of the device (0 means no effect and 10 means complete satisfaction. Values for each answer will be interpreted separately and a 10 signifies a better outcome); dichotomous (yes/no) questions about the device, where "no" signifies no interruption to their different routines and therefore "no" represents a better outcome; and free-answer questions to collect qualitative data on concerns and recommendations.

    Measured: 10 minutes

Questions about this trial

What is this clinical trial studying?

A study testing Wearable EMG/Vibration device in people with Spinal Cord Injuries, run by Shirley Ryan AbilityLab 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 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: status not confirmed, as of the sponsor's last update on 25 May 2021. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Monica Perez, PhD, PT (312-238-2886, mperez04@sralab.org), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Changes in muscle spasms with vibration device (time frame: 4 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 25 May 2021.
