Brief Summary

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).

Outcome Measures

Primary Outcomes (5)

  • Setup cueing device

    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

    Items defined by the System Usability Scale: 5-point Likert scale ('strongly disagree' to 'strongly agree').

    2 weeks

  • Usability

    Usability of the cueing device is measured by a self-developed questionnaire.

    2 weeks

  • Acceptance

    Acceptance is measured by a self-developed questionnaire.

    2 weeks

  • Frequency using the device

    How often the device is used (counts logging protocol).

    2 weeks

Secondary Outcomes (6)

  • Walking speed [meters/second]

    1 week

  • Cadence [steps/minute]

    1 week

  • Walking distance [in meters]

    1 week

  • Step length right/left [in meters]

Intervention

EXPERIMENTAL

Using the Tactile Cueing Device

Device: Tactile Cueing Device

Interventions

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.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • 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.

You may not qualify if:

  • 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).
