About this study
Official title: Assessing the Use of Lasers on Shoes for Freezing of Gait in People With Parkinson's Disease: A Pilot Study
The purpose of this study is to assess the effectiveness of the visual cues of a wearable device in preventing freezing of gait (FOG) in those with PD.The aim is to investigate the impact of laser shoe attachments on gait in single and dual-tasking scenarios, as well as "real-world" mobility scenarios, in people with PD who freeze. For this study, participants will wear sensors on their feet, hips, chest, and head to show stride length, foot angle, and foot height, and head position during different gait assessments. The patients will do the gait assessments without the laser shoes and with the laser shoes to determine how the laser shoes affect freezing of gait. The gait assessments include having the patient complete a two minute walk, two minute walk with another task (reciting every other letter of the alphabet), obstacle course, obstacle course with another task (reciting every other letter of the alphabet), and quickly turning in place. The assessments are activities that are performed in everyday activities so there are no risks associated with these requested tasks. These activities will be done in a lab at the Phoenix Biomedical Campus. Safety for the participants will be monitored by placing a belt around the waist of the participant with a member of the research personnel close by in case the participant demonstrated a shift in their balance. The research member can use the belt to provide stability and secure the participant, preventing them from further loss of balance. Moreover, three different activities of daily living (ADL's) will be assessed with and without the laser shoes in a simulated apartment environment located at the Phoenix Biomedical campus. The ADL's include walking from the bed to the kitchen, walking from the living room to the kitchen and making tea in the microwave, and answering the door. The activities to be done in the apartment setting will be video-recorded and analyzed. Some participants will be given the laser shoes to take home and use for one week. The same protocol explained above will be used to assess freezing of gait after this one week in those selected participants. To assess retention of improvements, the participants who took the laser shoes home will also be given the same protocol two days later (after not having used the laser shoes during that time). Participants will also complete surveys for quality of life, freezing and gait and cognitive function. A standard test for balance will also be conducted.
Read the detailed description
15 individuals with Parkinson's Disease will complete two tasks: a gait task and an activity of daily living (ADL) task both with and without the use of laser shoe attachment. The gait task involves 5 separate scenarios: 2 min walk with a single and dual-task trial, obstacle course with a single and dual-task trial, and a quick turn-in-place. For the dual-task trials, participants will complete the 2 min walk and obstacle course scenarios in addition to a cognitive task (e.g. reciting the alphabet every other letter). During the single-task trials for the 2 min walk and obstacle course, participants will complete these activities without a cognitive task. Participants will also be required to fill out surveys for quality of life, balance and freezing of gait. A standard test for balance will be conducted (MiniBEST). Participants will be assessed using the UPDRS in order to categorize the level of Parkinson's Disease. Permission and training for use of the UPDRS will be obtained prior to testing participants.
The ADL task involves three "real-world" mobility scenarios, in which participants will be asked to: walk from the bedroom to the bathroom and also the kitchen, make tea in the kitchen, and move from the couch to answer the front door.
For both tasks, gait will be characterized during each scenario using inertial sensors (OPALs). Outcomes will include step length, foot angle and foot height (clearance from floor) and head movement. To characterize functional movements we will video movements during all scenarios for both tasks. Outcomes will be the number and temporal length of each freezing event, to be determined by a movement disorders neurologist.
A subset of participants (n=3) will use the sensors at home for 1 week, and return to the lab for gait and functional task assessment. They will return after a 2-day washout (no sensors) to assess retention of improvements from the 1-week exposure.

What is being measured
The primary outcome is the main question the study is designed to answer.
Freezing Severity
The severity of freezing during a gait task, as quantified by review of a video of the movement, assessed by a trained reviewer
Measured: 4 hours
Secondary outcomes (1)
Freezing of Gait Ratio
Freezing of gait (FoG) ratio is calculated from acceleration of the shins (measured via inertial sensors, Opals by APDM) in-place turning. First, power spectral density from antero-posterior acceleration signals are calculated. Then, a FoG ratio is calculated as the ratio of total power in the "freezing band" (3-8 Hz) and the "locomotion band" (0.5-3 Hz). Higher freezing ratios indicate higher severity of FoG. (Tang et al., 2019).
Measured: This outcome will be assessed during in-place turning with and without laser shoes (both collected within the same data collection). The time frame will be 2 hours with or without the lasers followed by 2 hours without or with the lasers.

Questions about this trial
What is this clinical trial studying?
A study testing gait task and activity of daily living task in people with Parkinson Disease, run by Northern Arizona 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 1 inclusion and 1 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: status not confirmed, as of the sponsor's last update on 23 Nov 2021. 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Cindy C Ivy, OTD ((602) 329-3878, Cynthia.Ivy@nau.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Freezing Severity (time frame: 4 hours). 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 NCT05131906, which also lists 4 linked publications.
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 23 Nov 2021.
