About this study
This is a multi-site feasibility trial of an embedded emergency department (ED) physical therapy care model for dizziness at two EDs in the Northwestern Medicine and University of Utah Health systems. The study intervention (embedded ED physical therapy) is a reconceptualization of the traditional outpatient physical therapy care model in which we place a physical therapist directly in the ED to initiate timely care for patients with dizziness; we previously evaluated this intervention in a single center randomized trial for low back pain. This multi-site feasibility trial will be comprised of 9 months of active intervention and 12 months of longitudinal data collection. The two sites will be parallel randomized 1:1 to receive either the embedded ED physical therapy condition (intervention, n=1) or usual care (control, n=1) via simple randomization. This trial focuses on feasibility outcomes - such as our ability to enroll participants, deliver the intervention with fidelity, and collect longitudinal patient-reported outcome data and electronic health record data.
Read the detailed description
After a 12-month milestone-driven planning and preparation phase, we will conduct a 21-month randomized feasibility clinical trial of the embedded ED physical therapy intervention at the Northwestern Medicine and University of Utah health systems, comprised of 9 months of active intervention and 12 months of longitudinal data collection. Two hospital EDs (Northwestern Memorial Hospital, University of Utah Hospital) will be randomized to receive either the embedded ED physical therapist intervention (treatment, n=1) or usual care (control, n=1). Following completion of the feasibility trial, the control site will receive the intervention as per standard waitlist procedures for randomized trials. A third hospital ED (Northwestern Lake Forest Hospital) will not participate in randomization or participant enrollment but will contribute baseline electronic health record data to assist in feasibility assessments for a future full-scale trial.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Embedded Emergency Department Physical TherapyOther
We place a physical therapist directly in the emergency department to initiate timely care for patients with dizziness rather than waiting on an outpatient referral to physical therapy, which can often take weeks to accomplish, if ever at all. The actual techniques and approaches used by the embedded ED physical therapist in this study (e.g., exercises, maneuvers, coaching) are standard-of-care and do not involve investigational interventions, devices, or drugs.
Usual CareOther
Standard-of-care treatment for dizziness presenting in the emergency department

What is being measured
The primary outcome is the main question the study is designed to answer.
Longitudinal participant surveys (effectiveness): missing data rate for the Dizziness Handicap Inventory
Rate of missing data for assessments administered between baseline and 12 months. Variable type: binary / proportion.
Measured: 12 months
Longitudinal participant surveys (effectiveness): screening-to-enrollment ratio
Number of participants who enter screening compared to the number of participants who enroll in the study. Variable type: binary / proportion.
Measured: Baseline
Longitudinal participant surveys (effectiveness): participant retention rate defined as completion of at least one follow-up survey.
Ratio of participants enrolled to the number who complete at least one follow-up survey.
Measured: 12 months
Electronic Health Record (EHR) extraction (implementation): adoption of Emergency Department (ED) physical therapy
Adoption is defined as the number of potentially eligible dizziness ED visits have a documented order for a physical therapy evaluation. Cross-sectional at the level of site/Emergency Department during the trial. Variable type: Proportion.
Measured: Baseline
Electronic Health Record (EHR) extraction (implementation): fidelity of Emergency Department (ED) physical therapy
Fidelity is defined as the number of dizziness ED visits that have a structured research note documenting use of the protocol. Cross-sectional at the level of site/Emergency Department (ED) during the trial. Variable type: proportion.
Measured: Baseline
Clinician surveys before and after implementation of the intervention (implementation): Normalisation Measure Development Questionnaire (NoMAD) questionnaire scores
1-6 months prior to opening study to accrual and 1-6 months after the last participant enrolls at the site. Variable type: continuous.
Measured: 1-6 months prior to opening study to accrual and 1-6 months after the last participant enrolls at the site.
Secondary outcomes (7)
Longitudinal participant surveys (effectiveness): a sum of the missing data rate for the remaining Participant Reported Outcomes (PROs) combined.
Missing data rate for each PRO will not be analyzed separately, but will be combined into one measurement as one outcome. PROs: nine-item Vestibular Activities Avoidance Instrument (VAAI), Global Rating of Change, Numeric Pain Rating Scale, additional healthcare utilization (e.g., physical therapy, ED, doctor's office), and a medication use survey.
Measured: 12 months

Measured: 12 months
Electronic Health Record (EHR) extraction (effectiveness): rate of advanced diagnostic imaging
Variable type: count, may be considered binary / proportion

Questions about this trial
What is this clinical trial studying?
A study testing Embedded Emergency Department Physical Therapy in people with Dizziness, run by Northwestern University at 2 sites 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 5 inclusion and 4 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: looking for participants now, as of the sponsor's last update on 7 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Howard Kim, MD, MS (312-926-0591, howard.kim@northwestern.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Longitudinal participant surveys (effectiveness): missing data rate for the Dizziness Handicap Inventory (time frame: 12 months). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 7 Apr 2026.
