Usability of a Novel Cueing Device for Patients With Parkinson's Disease (TCP)

January 11, 2024 updated by: Swiss Federal Institute of Technology

Usability Study of a Novel Tactile Cueing Device for Patients With Parkinson's Disease: A Monocentric Interventional Study

Hypokinetic gait disorder and Freezing of Gait (FOG) are frequent symptoms in the advanced stage of Parkinson's disease (PD). These impair quality of life and significantly increase the risk of falls. External movement pacemakers have been developed to improve gait and avert FOG by cueing strategies. The investigators developed a smart, small and lightweight, easy-to-handle wearable tactile cueing device (TCD), consisting of a control unit, two pulse generators and a battery-driven power supply. The device is programmed via a Graphical User Interface (GUI).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Include patients who suffer from advanced PD. Characteristic symptoms of parkinsonian gait like hypokinetic movements and/or FOG have to be present.
  • Parkinsonian gait is measured by the following items of the Movement Disorder Society Unified Parkinson Disease Rating Scale (MDS-UPDRS): item 2.12, item 2.13, item 3.10 and item 3.11. The Hoehn and Yahr (HY) stage during ON is 1-4/5.
  • MoCA ≥ 22/30.
  • Participant has signed the informed consent.

Exclusion Criteria:

  • Inability of the participant to understand the IC or to follow the procedures of the study (as judged by the Qualified Physician).
  • Significantly, impaired cognitive skills render the participant unable to use the TCD.
  • Presence of severe motor fluctuations and severely impaired walking ability as defined by HY stage V during ON.
  • Clinically relevant skin lesions on the wrist or fixation points (usually the thighs).

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Intervention
Using the Tactile Cueing Device
Device: Tactile Cueing Device
Each participant receives an individual training on how to use the Tactile Cueing Device and the set-up of the TCD will be done according to the results of a 10MWT and the participant's preferences. Gait assessments with an activated or deactivated TCD are executed using the Timed Up and Go test, the 2-Minute Waling test and a treadmill (C-Mill). Also a long-term test run of the TCD during one day is planned.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Setup cueing device
Time Frame: 2 weeks
Time needed for the setup [in seconds] and the variations of the different setup parameters (cueing length [seconds], cueing strength [% of maximum], cueing cadence [count/minutes]) between the days of usage. Overall descriptive summary of the variation between the different setup parameters during the days of usage.
2 weeks
System Usability Scale
Time Frame: 2 weeks
Items defined by the System Usability Scale: 5-point Likert scale ('strongly disagree' to 'strongly agree').
2 weeks
Usability
Time Frame: 2 weeks

Frequency using the device
Time Frame: 2 weeks
How often the device is used (counts logging protocol).

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
