Outcome Measures

Primary Outcomes (1)

  • Changes in severity of the freezing of gait phenomenon: percentage time frozen (%TF)

    %TF is determined based on video annotations of the full FOG-provoking protocol (OFF+ON) during the pre- and post-intervention assessment (T1 and T2). %TF = (summed duration FOG during FOG-provoking protocol ON+OFF)/(total duration FOG-provoking protocol OFF+ON)\*100%. Freezing includes episodes of akinetic FOG, trembling FOG and festination.

    immediate post-intervention

Secondary Outcomes (9)

  • Changes in severity of the freezing of gait phenomenon: %TF OFF medication

    immediate post-intervention

  • Changes in severity of the freezing of gait phenomenon: %TF ON medication

    immediate post-intervention

  • Change in number and duration of FOG episodes (video-based)

    immediate post-intervention

  • Changes in severity of the freezing of gait phenomenon (subjective measurement): score on new Freezing of Gait questionnaire (NFOG-Q).

    immediate post-intervention

  • Changes in physical activity, as recorded using an accelerometer placed on the lower back.

    One week post-intervention

  • +4 more secondary outcomes

Eligibility Criteria

Age40 Years - 90 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Clinical diagnosis of Parkinson's disease (PD) (n=31 per site) according to the UK PD Society Brain Bank criteria
  • Modified Hoehn \& Yahr Stage I to IV in the ON-state;
  • Age between 40 and 90 years;
  • Ability to walk 5 minutes while unassisted by another person;
  • Mini-Mental State Examination (MMSE) score of \>= 21 or \> 16 on the 26-item MMSE screening;
  • Stable PD medication during the previous month and no medication change foreseen for the next 6 weeks.
  • Self-reported freezing of gait (FOG) severity of at least 1 FOG episode per day, based on Characterizing of Freezing of Gait Questionnaire, irrespective of FOG occurring ON- or OFF-medication.

You may not qualify if:

  • Participation in another clinical study;
  • Use of a cueing device as normal practice;
  • A fall frequency of more than once a day;
  • Acute musculoskeletal or other neurological or cardiovascular conditions affecting gait or any other medical condition which, in the opinion of the investigator, may prevent completing the protocol;
  • Hearing problems, precluding use of auditory feedback from the DeFOG system;
  • The occurrence of any of the following within 3 months prior to informed consent: orthopedic surgery of the lower extremity, myocardial infarction, hospitalization for unstable angina, coronary artery bypass graft, percutaneous coronary intervention, implantation of a cardiac resynchronization therapy device, implantation of deep brain stimulation;
  • Substance abuse, major depressive disorder or clinical apathy that affects daily walking activity or may interfere with the patient's compliance;
  • Inability to walk without a rollator indoors;
  • Use of a Duodopa® or apomorphine injections, jeopardizing OFF-medication assessments;
  • Absence of clinically observed FOG during the FOG-provoking assessment at the pre-intervention assessment (T1).

Masking Details
Prior to randomization, all participants will be informed that the goal of the study is to compare the effects of two types of feedback about physical activity on freezing of gait. By withholding information about the cueing intervention, we hope that the participants in the control group will not realize that they are in the control group, in order to avoid a lack of motivation in this group. The intervention group will probably become unmasked after group allocation, as the cueing therapy was not mentioned in the informed consent. During the post-assessment, the FOG provoking protocol will be performed with and without cueing. This induces the risk of the investigator/outcome assessor becoming unmasked, as patients in the control group may mention that this cueing option is something they haven't experienced during the intervention period. In order to prevent this, the therapist will ask patients in the intervention group to also act surprised to the cueing modality.

Intervention Model
PARALLEL
Model Details: This is an interventional study with a parallel design, consisting of pre- and post-assessments, 2x (pre- and post) 7 days of free-living gait monitoring and an intervention/control period of 4 weeks. The pre-assessment and first week of free-living gait monitoring will take place prior to randomization.
