Reproducibility of Virtual Exercise Assessments Versus Face-to-face Exercise Testing in Adults With Cystic Fibrosis

NCT06565832 | Completed

• 1 other identifier: RExA-CF V3
• Study Type: interventional
• Target: 19
• Locations: 1 country
• Sites: 1

Brief Summary

RExA-CF is investing if results from exercise tests (the Chester Step Test and the One-Minute Sit-to-Stand test) completed face to face are comparable to results of the same tests completed via a virtual teleconferencing platform. The study involves two exercise testing sessions (one face-to-face and one via a video link), with participants being randomised to complete the two exercise tests (the 1-minute sit-to-stand test and the Chester Step test). The two testing sessions will be completed within three weeks of each other, the order of which will be randomly allocated. One session will be completed face-to-face during a pre-arranged visit to the hospital, the other test session will be completed through a video call at a time convenient to the participants. After the second testing session participants will be asked some questions about the face-to-face and video tests to get their views about the two formats.

Outcome Measures

Primary Outcomes (2)

• Aerobic Capacity from the Chester Step test

  This test involves the participant stepping up and down off of a step (this can be a bottom stair or doorstep at home) keeping up with the beat of a recording. The speed of the beat increases every 2 minutes, and the test continues until the participant cannot keep up with the pace, wish to stop or the test ends which takes 10 minutes. Participants will be asked to take their heart rate and oxygen levels before and after the test using a provided pulse-oximeter. This test should take a maximum of 15 minutes. The results of the test will be used to calculate the participants aerobic capacity (range 0-60)

  Completed at week 0 and within 2 weeks of first test

• Number of sit to stands completed during One-Minute Sit-to-Stand test

  This test involves the participant sitting down and standing up from a normal height chair (can be a dining room or kitchen chair at home) for one minute. Participants can rest or stop at any time if fatigued. This test should take a maximum of 5 minutes.

ACTIVE COMPARATOR

The One-Minute Sit-to-Stand test and the Chester Step test will be completed via a video link call with the participant and the research team.

Procedure: One-Minute Sit-to-Stand Test; Procedure: Chester Step Test

Face-to-Face exercise testing

ACTIVE COMPARATOR

The One-Minute Sit-to-Stand test and the Chester Step test will be completed face to face at a hospital appointment with the participant and the research team.

Procedure: One-Minute Sit-to-Stand Test; Procedure: Chester Step Test

Interventions

One-Minute Sit-to-Stand Test PROCEDURE

This test involves sitting down and standing up from a normal height chair (can be a dining room or kitchen chair at home) for one minute. Participants can rest or stop at any time if fatigued. Participants will be asked to record your heart rate and oxygen levels before and after the test and will be given a monitor to do this with if they do not already have one. This test should take a maximum of 5 minutes.
