Clinical Trial 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).

Gender All
Age group 18 Years and older
Eligibility 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).

Intervention

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.

Outcome

Type Measure Description Time frame Safety issue
Primary 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
Primary System Usability Scale Items defined by the System Usability Scale: 5-point Likert scale ('strongly disagree' to 'strongly agree'). 2 weeks
Primary Usability Usability of the cueing device is measured by a self-developed questionnaire. 2 weeks
Primary Acceptance Acceptance is measured by a self-developed questionnaire. 2 weeks
Primary Frequency using the device How often the device is used (counts logging protocol). 2 weeks
Secondary Walking speed [meters/second] Calculated by the assessments 10 meter walk test and 2-minute walk test. 1 week
Secondary Cadence [steps/minute] Number during 10 meter walk test. Also measured by a system of movement analysis (C-Mill MOTEK). 1 week
Secondary Walking distance [in meters] Measured by a digital measuring wheel during 2-minute walk test. Also measured by a system of movement analysis (C-Mill MOTEK). 1 week
Secondary Step length right/left [in meters] Measured by a system of movement analysis (C-Mill MOTEK). 1 week
Secondary Initial step latency [in seconds] Extracted from video documentation by a blinded rater. 1 week
Secondary Number of FOG Extracted from video documentation by a blinded rater. 1 week
