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.

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.

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.

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

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

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.

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.
