Usability Evaluation of the Safer Seat

Not Applicable

Recruiting

• Conditions: Impaired Mobility; Impaired Balance

• Registration Number: NCT07011446
• Lead Sponsor: Julie Faieta

Brief Summary

This is an initial usability assessment of a vehicle Seat Transfer device, the Safer Seat. The study will involve target end users (individuals with mobility impairments) trialing the Safer Seat and providing feedback via the Technology Acceptance Model Survey's Modified from Davis (1985) and brief qualitative interview.

Detailed Description

This study investigates the initial usability of the Safer Seat vehicle transfer aid. Participants with impaired mobility, strength, or balance are being asked to transfer onto and off of a vehicle seat with and without the device to trial its usability. In addition, transfers are doing rated by a licensed occupational therapist according to the Physical Mobility Scale to determine if independence level is affected. Usability evaluation is being done both qualitatively and quantitatively using Technology Assessment Surveys and a semi-structured interview. Insight gained through this initial trial will be used to refine the design of the Safer Seat.

Primary Outcome Measures

Name	Time	Method
Physical Mobility Scale	Day 1	Used to rate ability level in sit to stand and stand to sit transfers from 0 if not able to bear weight, to 5 if independent and not needing to use upper extremities for assistance.

Secondary Outcome Measures

Name	Time	Method
Technology Acceptance Model Perceived Ease of Use, Usefulness, and Attitudes Toward Use questionnaires	Day 1	Modified from Davis (1985) surveys to assess Perceived Ease of Use, Perceived Usability, and Attitudes Toward. Survey item responses on 5-item likert scale. Scoring progresses from Strongly Disagree (1) to Strongly Agree (5). For most items "Strongly Agree" indicase the individual favors the intervention. There are a few items phrased in a negative manner such that a response of "Strongly Disagree" indicates the individual favors the intervention; these items are reverse coded when scoring.
Demographic Data	Day 1
Semi structured interview	Day 1	Questions were focused on the usability and usefulness of the Safer Seat.
