Trial summary

Background: Many people who have had a traumatic brain injury have difficulty walking. Training on a treadmill is often used to help people with walking difficulties. Supporting a person s body weight with a harness while using the treadmill can help improve walking skills in people with brain injury. Read more about this study

About this study

Official title: Effect of Time Varying Walking Velocity in Body-Weight Supported Treadmill Training

Background:

  • Many people who have had a traumatic brain injury have difficulty walking. Training on a treadmill is often used to help people with walking difficulties. Supporting a person s body weight with a harness while using the treadmill can help improve walking skills in people with brain injury. Varying the rate at which people walk on the treadmill may also help more than walking at a constant rate. Treadmill training with body weight support or walking at different speeds may improve walking skills in people who have had a traumatic brain injury. More research is needed to see if one method is better than the other.

Objectives:

  • To compare the effects of two types of treadmill training in people who have had a traumatic brain injury.

Eligibility:

  • People at least 18 years of age who have had a mild or moderate traumatic brain injury at least 6 months ago and have mild or moderate walking difficulty.

Design:

  • Participants will be screened with a medical history and physical exam. They will also take a basic walking test (not on a treadmill).
  • Participants will be divided into two groups. The first group will have treadmill training at a constant speed. The second group will have treadmill training at different speeds. All participants will wear a support harness while walking on the treadmill.
  • At the first training visit, participants will have a gait assessment with different tests of walking. Then they will have a treadmill walking session.
  • After the first visit, participants will return twice a week for 6 weeks for treadmill training sessions (visits 3 through 12). They will also have grip strength and walking tests.
  • At the end of 6 weeks, participants will have a final treadmill training session, and will have a gait assessment exactly like the one in the first training visit.
  • At 6 months after the final session, participants will have a followup visit with a final gait assessment.
Read the detailed description

Objectives: To test the effectiveness of using time varying walking velocity in Body-Weight Supported Treadmill Training (BWSTT) as compared to using constant velocity in subjects with Traumatic Brain Injury (TBI). We hypothesize that using time varying velocity will result in a greater improvement in ambulatory function.

Study Population: 30 adult subjects with a clinical diagnosis of non-penetrating TBI and with functional deficits in gait will be enrolled. Subjects will be recruited from NIH, affiliated hospitals/clinics, and in the community.

Design: This pilot study will use an instrumented treadmill (Bertec Co., Columbus, Ohio) and a force controlled harness system called ZeroG (Aretech LLC, Ashburn, Virginia). Subjects will be randomly assigned to one of two groups (12 subjects per group): the first group will receive BWSTT at a constant velocity (also known as standard treadmill training); and the second group will receive BWSTT at randomized time varying velocity. BWSTT at time varying velocity consists of two components: 1) subjects passively adjusting their walking speed to the continuously changing speed of the treadmill; and 2) subjects actively changing their walking speed by following the instructed walking speed displayed on a monitor screen while the treadmill is automatically adjusted to the subjects speed. Each group will receive 8 gait training sessions (30 minutes per session, twice per week) for four weeks. Gait performance will be tested before (pre-test) and after (post-test) the 8 session gait training program.

Outcome Measures: The primary outcome measures are parameters representing gait performance: maximum walking speed, self-selected walking speed, cadence, stride length, percentage of swing, stance and double stance periods, gait symmetry, Time Up and Go (TUG), and Dynamic Gait Index (DGI) scores. The secondary outcome measure is physical and cognitive effort exerted during the training session as evaluated by grip-strength test and LNS (Letter-Number Sequencing) test.

What is being measured

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

  1. The primary outcome measures are parameters representing gait performance such as maximum/self-selected walking speed, cadence, stride length, Time Up and Go test scores and Dynamic Gait Index scores.

Secondary outcomes (1)
  1. The secondary outcome measures are physical and cognitive effort exerted during the training. Physical effort will be measured by grip strength. Cognitive effort will be estimated by Letter Number Sequence test.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Gait Training Method in people with Traumatic Brain Injury and Walking Impairment, run by National Institutes of Health Clinical Center (CC) 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 8 inclusion and 9 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 16 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.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early. Results are not available in the source record.

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 measures are parameters representing gait performance such as maximum/self-selected walking speed, cadence, stride length, Time Up and Go test scores and Dynamic Gait Index scores.. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01419522, which also lists 3 linked publications.

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 16 Dec 2019.
