Trial summary

The purpose of this study is to investigate the impact of a specifically designed ankle foot orthosis (AFO, hinged, with Tamarack joint and adjustable check strap) on the spatial and temporal gait parameters, electromyography (EMG) and walking endurance, in select individuals living with Parkinson's disease.

About this study

Official title: Investigation of Lower Extremity Orthoses on Gait in Persons With Parkinson's Disease: a Case Series.

The purpose of this study is to investigate the impact of a specifically designed ankle foot orthosis (AFO, hinged, with Tamarack joint and adjustable check strap) on the spatial and temporal gait parameters, electromyography (EMG) and walking endurance, in select individuals living with Parkinson's disease.

Read the detailed description

This study will be 10 weeks long. Following fitting with unilateral or bilateral custom-fabricated AFOs the subject will participate in 4 gait training sessions which will be at weeks 1, 2, and 7. Each training session will be 45-60 minutes in duration. Various outcome measures will be completed at the following times: time of consent (T1), treatment 1 at time of brace delivery (T2), week 5 (T3), and week 10 (T4). Subjects will be closely monitored throughout the 10 week study and will be unenrolled by self-request or the following medical reasons: 1. New diagnosis with direct consequences affecting gait training, 2. Inability to tolerate the study AFO(s).

What participants receive

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

  • Ankle foot orthosisDevice

    Also called Tamarack with check strap

    Participants will receive a Tamarack ankle foot orthosis with a check strap for gait training as well as a home walking program.

Receives: Device: Ankle foot orthosis

What is being measured

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

  1. Change in Step Length by Means of Computerized Gait Analysis From Initial to Final Testing

    Participants will be asked to walk on a 12-16 foot long vinyl pad placed on the floor. The mat will record and analyze step length.

    Measured: Done at time of enrollment in the study, i.e. baseline and 10 weeks post enrollment

Secondary outcomes (1)
  1. Number of Participants With a Change in Electromyography of Key Lower Extremity Muscles From Initial to Final Testing

    Surface electromyography will be done on key muscles in the lower extremity (quads, anterior tibialis, gastrocnemius) during computerized gait assessment. Changes in EMG activity include things such as increases in amplitude or timing that might indicate increases in strength or motor learning as a result of wearing the ankle foot orthosis.

    Measured: Done at time of enrollment in the study, i.e. baseline and week 10 post enrollment.

Questions about this trial

What is this clinical trial studying?

A study testing Ankle foot orthosis in people with Parkinson's Disease, run by University of Texas Southwestern Medical Center 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 6 inclusion and 3 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 3 Aug 2015. 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 3 Aug 2015). 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?

Change in Step Length by Means of Computerized Gait Analysis From Initial to Final Testing (time frame: Done at time of enrollment in the study, i.e. baseline and 10 weeks post enrollment). 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 3 Aug 2015.
