Trial summary

The aim of this pilot/feasibility study is to test if delivering rhythmic vibration cues to the lower legs, specifically in response to gait defects (rather than continuously), can improve walking quality and overcome gait freezing in Parkinson's disease. Read more about this study

About this study

Official title: Investigating Responsive Vibration Cueing Modalities From a Wearable Device to Overcome Gait Freezing in Parkinson's Disease

The aim of this pilot/feasibility study is to test if delivering rhythmic vibration cues to the lower legs, specifically in response to gait defects (rather than continuously), can improve walking quality and overcome gait freezing in Parkinson's disease.

During the study, people with Parkinson's disease that suffer from regular (daily) gait freezing will undertake a series of walking/activity circuits, receiving continuous cueing, responsive cueing (delivered in response to gait freezing), no cueing and no device. Vibration cueing is provided by a non-invasive wearable device prototyped at the University of Oxford, worn on the lower legs during 3 circuits. A series of walking metrics will be analysed.

Read the detailed description

Parkinson's disease (PD) is a progressive, neurodegenerative disorder that impairs the ability to control movement. Gait freezing is an inability to walk spontaneously and continuously, and affects nearly half of PD patients, reducing quality of life and contributing to increased fall risk. Cueing (with visual, auditory or somatosensory stimuli) is an effective way to improve walking quality in people with PD. In this pilot study we aim to test if delivering rhythmic vibration cues acutely, specifically in response to gait defects, can improve walking quality and overcome gait freezing in PD.

During the study, people with PD that suffer from regular (daily) gait freezing, but who are able to stand and walk with minimal assistance, undertake 4 walking/activity circuits. During each of the circuits participants receive either continuous cueing, responsive cueing (delivered in response to gait freezing), no cueing and no device. Cueing is provided by a non-invasive wearable movement-tracking cueing device prototyped at the University of Oxford (approximately the size of a smart phone), worn on the lower legs during 3 circuits. The ordering of the interventions/circuits are systematically alternated for each participant. The impact of responsive cueing on walking ability can be determined by analysis of walking metrics across the circuits.

What participants receive

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

  • Rhythmic vibration cueing (lower leg)Device

    A non-invasive wearable device worn against both gastrocnemius muscles provides rhythmic vibrations when triggered.

Single arm of studyExperimentalSingle Arm. During each study session the participant undertakes 4 walking/activity circuits. During each circuit the participant receives either continuous cueing, responsive cueing (delivered in response to gait freezing), no cueing and no device.

What is being measured

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

  1. Step frequency

    The primary objective is to test if gait-freeze initiated vibration cues, provided at the lower-leg, can improve gait/walking quality in PD patients. The primary outcome measure will be cadence (step frequency) with other gait measurements including frequency and duration of gait freeze events, continuous walking time, left/right rhythm and stride length. Measurements extracted from video data collected during 1 hour study sessions. Change in these measurements assessed between cued (intervention) and no-cue (no intervention) walking circuits for each participant.

    Measured: Data collected during 1 hour sessions up to study completion.

Secondary outcomes (1)
  1. Automated gait freeze detection

    Generation of algorithms capable of recognising gait freeze events from device movement data with >80% accuracy. Algorithm development to identify changes in accelerometer (g) and gyroscope (rsp) data from leg-worn devices indicative of gait freeze events. Algorithm accuracy expressed as % sensitivity and % specificity for identifying gait freeze events from movement data relative to observer time stamps.

    Measured: Movement data collected during 1 hour sessions up to study completion.

Questions about this trial

What is this clinical trial studying?

A study testing Rhythmic vibration cueing (lower leg) in people with Parkinson's Disease, run by University of Oxford at 1 site in United Kingdom.

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 7 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: finished, as of the sponsor's last update on 24 Aug 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 Kingdom. 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?

Step frequency (time frame: Data collected during 1 hour sessions up to study completion.). 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 24 Aug 2021.
