About this study

The goal of this intervention is to explore the effectiveness of a Turning Intervention (TURN-IT) to improve quality of turning in participants with Parkinson's Disease (PD). An unique exercise program has been developed - TURN-IT - in which participants practice exercises that focus on physiological constraints that impair turning ability, such as axial rigidity, narrow base of support, bradykinesia, and inflexible set-shifting. The 60 participants with PD and a history of falls in the previous 12 months, will be randomized into a 6-week, 3x/week, one-on-one TURN-IT group or No-Intervention Control group. This pilot intervention study will determine the number of subjects needed for a future clinical trial and will determine the sensitivity to change with rehabilitation our daily-life turning quality measures (such as, mean and variability of number of steps to turn, turn amplitude, turn velocity). The investigators predict that the TURN-IT program will improve turning in daily life enough to justify a larger clinical trial.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • TURN-IT exercise programBehavioural

    Based on the exercise motor learning principles, participants spend 10-15 minutes at each Exercise Station that focuses on particular constraints of turning ability. The stations will focus on important underlying aspects of turning, such as weight-shifting and increasing axial rotation during functional turning tasks. Each station will be progressed across levels to make more challenging (such as adding a dual task). Initially participants will be supported in an overhead body-weight support system (ZeroG) to allow them to practice challenging exercises without the risk of falling.

Study groupRoleWhat they receive
TURN-IT groupExperimentalParticipants in the treatment group will attend supervised, 1-hour classes, 3 times per week for 6 weeks, one-on-one with the same exercise trainer, overseen by a physical therapist investigator.

No Intervention Control GroupNo interventionParticipants in this group will be tested at baseline and 6 weeks later. They will go about their normal daily life during the 6 week period.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Variability in Number of Steps to Complete a Turn

    The coefficient of variation in the number of steps in a turn, averaged from daily monitoring, as measured at 6 weeks.

    Measured: 6 weeks

Secondary outcomes (9)
  1. Change in Falls Efficacy Scale International

    The difference in the Falls Efficacy Scale, as measured at baseline and 6 weeks. The Falls Efficacy Scale is a 16 item self-administered questionnaire to assess fear of falling. Scores range 16-64 with higher score indicating more fear of falling.

    Measured: baseline and 6 weeks

  2. Prospective Fall Incidence

    Number of prospective falls recorded for 12 months starting from the end of intervention

    Measured: 52 weeks

  3. Patient Global Impression of Change

    Question of participant's rating of mobility. Score range from 1-7 with 1-3 indicating improvement, 4 no change, and 5-7 worsening of mobility. Single score provided at the end of 6 week period.

    Measured: 6 weeks

  4. Number of Steps to Complete a Turn

    The number of steps in a turning averaged from daily monitoring, as measured at 6 weeks.

    Measured: 6 weeks

  5. Turn Peak Velocity

    Peak velocity of turns averaged from daily monitoring, as measured at 6 weeks.

    Measured: 6 weeks

  6. Turn Angle Amplitude

    The peak size of turn angles averaged from daily monitoring, as measured at 6 weeks.

    Measured: 6 weeks

  7. Turn Duration

    Time to complete turns averaged from daily monitoring, as measured at 6 weeks.

    Measured: 6 weeks

  8. Variability of Double-support Time

    The coefficient of variation in time of double-support phase, as measured at 6 weeks.

    Measured: 6 weeks

  9. Lateral Trunk Range

    The range of motion in the trunk during walking, in the lateral direction, as measured at 6 weeks.

    Measured: 6 weeks

Questions about this trial

What is this clinical trial studying?

A study testing TURN-IT exercise program in people with Parkinson Disease, run by Oregon Health and Science University at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 6 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 6 Nov 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Variability in Number of Steps to Complete a Turn (time frame: 6 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04897256, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Nov 2026.
