Outcome Measures

Primary Outcomes (2)

  • Postural Instability / Gait Difficulty

    MDS-UPDRS subscore (ranging 0-20). Higher score is worse.

    From enrollment to the end of the study at eight months.

  • Lower Body Gait score

    MDS-UPDRS subscore (ranging 0-36). Higher score is worse.

    From enrollment to the end of the study at eight months.

Secondary Outcomes (7)

  • Patient Global Impression of Change

    From enrolment to the end of the study at eight months.

  • New Freezing of Gait Questionnaire

    From enrolment to the end of the study at eight months.

  • Active Balance and Confidence scale

    From enrolment to the end of the study at eight months.

  • Parkinson's Disease Questionnaire - 39

    From enrolment to the end of the study at eight months.

  • Berg Balance Scale

    From enrolment to the end of the study at eight months.

  • +2 more secondary outcomes
