Evaluating the Effect of the Zeen Mobility Device on Clinical Practicality, Safety, and Impact (Via Assessments of Walking, Standing Tolerance, Balance, Endurance, Effort, and Participation in Daily Tasks) in an Outpatient Rehabilitation Setting for Individuals With Mobility Impairments.

November 2, 2026 updated by: Casa Colina Hospital and Centers for Healthcare

Evaluating Functional Outcomes and Clinical Feasibility of the Zeen Mobility Device in Outpatient Rehabilitation

The goal of this clinical trial is to learn whether the Zeen Mobility Device can improve mobility and function during outpatient rehabilitation for adults with mobility impairments. The study will also evaluate the safety of the device and how easy it is for participants and therapists to use during routine therapy.

The main questions it aims to answer are:

  • Does using the Zeen Mobility Device improve walking, standing, transfers, and daily function compared with a participant's usual mobility device?
  • Can the Zeen Mobility Device be safely incorporated into outpatient rehabilitation?
  • How satisfied are participants and therapists with using the device during therapy?

Researchers will compare participants' performance using the Zeen Mobility Device with their performance using their usual mobility device, such as a walker or wheelchair. Participants will serve as their own comparison group.

Participants will:

  • Complete a baseline assessment before starting the study, a midpoint assessment after 4 treatment sessions, and a final assessment after 8 treatment sessions.
  • Attend 8 outpatient physical therapy sessions that include use of the Zeen Mobility Device.
  • Use the Zeen Mobility Device for at least 15 minutes during each study visit for balance, mobility, walking, transfer, or standing activities selected by their therapist.
  • Complete mobility and functional tests using both the Zeen Mobility Device and their usual mobility device at each assessment visit.
  • Provide feedback about their experience using the device while researchers monitor safety and any device-related problems.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Timed Up and Go
Time Frame: Baseline, 2 weeks, and 4 weeks

The Timed Up and Go Test is a clinical tool used to evaluate functional mobility, balance, walking ability, and fall risk in older adults and individuals with neurological or musculoskeletal conditions. Scoring is measured in seconds to complete the task. Higher scores indicate worse mobility, balance, and walking ability.
Baseline, 2 weeks, and 4 weeks
10 Meter Walk Test
Time Frame: Baseline, 2 weeks, and 4 weeks

The 10 Meter Walk Test is an assessment of a person's walking speed as they walk 10 meters, measured in seconds. A higher score indicates worsening balance and walking capacity, and is associated with poorer home and community access and increased fall risk
Baseline, 2 weeks, and 4 weeks
6 Minute Walk Test
Time Frame: Baseline, 2 weeks, and 4 weeks

The 6 Minute Walk Test is an assessment of a person's walking endurance as they walk during a 6-minute period, measured in total distance walked in meters. A higher score is associated with better walking endurance and capacity, and is associated with better home and community access and decreased fall risk
Baseline, 2 weeks, and 4 weeks
Barthel Index
Time Frame: Baseline, 2 weeks, and 4 weeks

The Barthel Index is an ordinal clinical scale that measures a patient's level of functional independence in 10 basic activities of daily living and mobility. The scale calculates 10 items into a point total, from 0 to 100, with a higher score indicating a greater level of independence and decreased need for nursing and caregiver support.
Baseline, 2 weeks, and 4 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Patient Satisfaction and Exertion Survey
Time Frame: Baseline, 2 weeks, and 4 weeks

Participants will report satisfaction with the device on a 5-point Likert Scale, or a 10-point scale, including:

  • Comfort using the device
  • Choosing to use the device during rehabilitation
  • Comfort, ease of use
  • Effort required for sit-to-stand transitions
  • Difficulty with 90-degree turns
  • Difficulty with larger turns
  • Exertion during ambulation
  • Hand strain during operation
  • Overall fatigue during walking

Total scores range from 9 to 50, with a higher score indicating more difficulty with the device, and decreased satisfaction.
Baseline, 2 weeks, and 4 weeks
