Trial Outcomes & Findings for Does Endurance Improve With the Use of Passy-Muir Valve for Patients With Tracheostomy? (NCT NCT04941456)

NCT ID: NCT04941456

Last Updated: 2025-12-11

Results Overview

Borg Rating of Perceived Exertion is a self reported outcome score, based on a scale of 6 through 20 (20 being the hardest or most exertion, 6 being the least exertion). The first session will occur within 72 hours of the participant being cleared by Medical Staff for PMV use. Subsequent sessions will occur on every consecutive day following for 6 days total, Monday through Friday, until a minimum of 2 to maximum of 6 sessions are completed. This will equal 1 to 3 paired sessions. Average change will be calculated by using Post intervention scores subtracted by Pre intervention scores.

Measure
Speaking Valve, Then Open Tracheostomy
Participants perform the six-minute walk test each study session to assess ambulation distance, first using the Passy-Muir Valve on day 1 and then switching to an open tracheostomy on day 2. Participants will alternate back and forth between the Passy-Muir Valve and open tracheostomy until 3 sessions are completed with each condition. Open Tracheostomy: Participants will perform the six minute walk test with an open tracheostomy. Participants will complete 1 to 3 session over approximately three-weeks. PMV in place: Participants will perform the six minute walk test with a PMV in place. Participants will complete 1 to 3 sessions over approximately three-weeks.

PRIMARY outcome

Timeframe: The first paired study session (Day 1) will occur within 72 hours of the participant being cleared by Medical Staff for PMV use. The second paired session will occur the day after session 1 (Day 2).

Population: Ambulation distance (feet)

During each session, Participants will be asked to walk as far as possible along a corridor for a period of six minutes. The distance the Participant walks will be recorded to compare if the Participant can walk further with or without the PMV in place. Participant can use a device to assist with balance and the Participant can be assisted by an investigator, if needed. Each session is scheduled in an alternating fashion for whether or not Participant will use the PMV (i.e. day one no PMV, day two with PMV, day three no PMV, day four with PMV). Participants will complete 3 sessions with the PMV in place and 3 sessions with an open tracheostomy. Study sessions will occur on consecutive days, five days a week, Monday through Friday, until a minimum of 2 to maximum of 6 sessions are completed. This will equate to 1 to 3 completed paired sessions.

Population: BORG change from before session to after session

Borg Rating of Perceived Exertion is a self reported outcome score, based on a scale of 6 through 20 (20 being the hardest or most exertion, 6 being the least exertion). The first session will occur within 72 hours of the participant being cleared by Medical Staff for PMV use. Subsequent sessions will occur on every consecutive day following for 6 days total, Monday through Friday, until a minimum of 2 to maximum of 6 sessions are completed. This will equal 1 to 3 paired sessions. Average change will be calculated by using Post intervention scores subtracted by Pre intervention scores.
