About this study

Official title: Comparative Analysis of Outcome Measures From Sit-to-stand Test Between Cystic Fibrosis and Healthy Subjects.

Introduction: In recent years, since the discovery of the cystic fibrosis (CF) transmembrane conductance regulator gene in human skeletal muscle, there appears to be growing interest in the measurement of muscle function in CF. One of the most used test in other chronic pulmonary diseases is the Sit-to-Stand test (STS) which consists of simply getting up from a chair. Although the main result of the STS test is the time developed during the task, the velocity and power generated during the task are considered very important variables to detect the functional decline. However, from our knowledge, no study has previously analyzed the differences in time, velocity and muscle power developed during the STS test in patients with CF and their respective healthy controls.

Objectives: To compare the values gained from handgrip strength, walking speed and STS test (time, velocity, and muscle power) in a group of patients with CF and their respective healthy controls, and to analyze if these differences (if any) are associated with lung function in patients with CF.

Methods: Cross-sectional study with a sample of 60 participants (30 patients diagnosed with CF and 30 healthy subjects) between 18-65 years old. The STS test will be measured through slow-motion video recording with a smartphone device (240 images per second) which will report the time, velocity and power generated during the test. Walking speed and handgrip strength will be also measured. Additionally, the relationship between the variables obtained during the test and the lung function of patients with CF will be analized.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Sit-to-stand time

    The time to complete the sit-to-stand test will be measured using a smartphone (Sit-to-stand App version 1.1) installed on an iPhone 6 running iOS 11 (Apple Inc., USA).

    To execute the test, subjects will sit on a rigid chair with their arms crossed over their chest with the hip, knee and ankle joints at approximately 90 degrees. The subjects will be instructed to stand-up as fast as possible. Participants will complete three STS repetitions to complete the test while standing without footwear.

    Measured: Cross-sectional baseline (non intervention)

  2. Sit-to-stand velocity

    The vertical velocity generated by the participants during the sit-to-stand test will be measured using a smartphone (Sit-to-stand App version 1.1) installed on an iPhone 6 running iOS 11 (Apple Inc., USA).

    To execute the test, subjects will sit on a rigid chair with their arms crossed over their chest with the hip, knee and ankle joints at approximately 90 degrees. The subjects will be instructed to stand-up as fast as possible. Participants will complete three STS repetitions to complete the test while standing without footwear.

    Measured: Cross-sectional baseline (non intervention)

  3. Sit-to-stand power

    The leg power generated by the participants during the sit-to-stand test will be measured using a smartphone (Sit-to-stand App version 1.1) installed on an iPhone 6 running iOS 11 (Apple Inc., USA).

    To execute the test, subjects will sit on a rigid chair with their arms crossed over their chest with the hip, knee and ankle joints at approximately 90 degrees. The subjects will be instructed to stand-up as fast as possible. Participants will complete three STS repetitions to complete the test while standing without footwear.

    Measured: Cross-sectional baseline (non intervention)

Secondary outcomes (3)
  1. Handgrip strength

    Handgrip testing will be performed in standing position with the arm at the side and the forearm and wrist placed into neutral. Using a digital hand dynamometer, subjects will squeez the device maximally. The test will be repeated two times on both the right and left hand with 30-s of rest between trials of the same hand. The greater of the two trials from the right and left side will be used and added together to give overall handgrip strength.

    Measured: Cross-sectional baseline (non intervention)

  2. Walking speed

    Self-selected walking speed will be determined by having participants walk at a pace they consider 'normal walking speed' over a distance of 8 m on a non-carpeted floor. To account for the time it will take participants to accelerate and decelerate, markers will be provided 2 m before and after the measured distance. Therefore, the total timed distance will be 4 m. The timed walking test will be completed twice to promote familiarity and improve accuracy.

    Measured: Cross-sectional baseline (non intervention)

  3. Lung function

    Lung function will be measured with a calibrated spirometer by a experimented nurse.

    Measured: Cross-sectional baseline (non intervention)

Questions about this trial

What is this clinical trial studying?

An observational study of Cystic Fibrosis, run by Universidad Católica San Antonio de Murcia at 1 site in Spain.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 26 Apr 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Sit-to-stand time (time frame: Cross-sectional baseline (non intervention)). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03524859, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Apr 2019.
