Trial summary

The 1-minute sit to stand (1-min STS) test is a standardized test which is used to examine exercise capacity in patients with chronic obstructive pulmonary disease (COPD). The chair seat height used is standardized to 46-48 cm. Read more about this study

About this study

Official title: The Impact of Chair Seat Height on the 1-Minute Sit to Stand Test Performance in Chronic Obstructive Pulmonary Disease: a Randomized Cross-over Study

The 1-minute sit to stand (1-min STS) test is a standardized test which is used to examine exercise capacity in patients with chronic obstructive pulmonary disease (COPD). The chair seat height used is standardized to 46-48 cm. Using a standard seat height for all patients - irrespective of their body height - may lead to invalid estimates of functional exercise capacity. The objective of this study is to assess whether there is a difference in repetitions during the 1-min STS test if the seat height is adjusted to 90° knee joint angle or the standard height chair of 46 cm is used.

Read the detailed description

In a single-center, randomized crossover study, the investigators aim to elucidate whether there is a difference in repetitions during the 1-min STS test if the seat height is adjusted to 90° knee joint angle or the standard height chair of 46 cm is used.

Patients with COPD referred for pulmonary rehabilitation will be invited to perform one standardised- (chair seat height 46cm) and one individualized (chair seat height adapted to 90° knee flexion) 1-min STS test on two different days in random order.

The tests will be performed after patients are familiarised with the 1-min STS testing procedure and learning effects can be excluded.

What is being measured

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

  1. Number of repetitions in the 1-min STS test

    difference in the amount of sit to stand repetitions in the 1-min STS test from a standard chair (46cm) or an individualized seat height chair of 90° knee joint angle

    Measured: During pulmonary rehabilitation, approximately 14 days

Secondary outcomes (1)
  1. Sit to stand power index

    The sit to stand power index is used to calculate the force-generating capacity (in watt) of the knee extensor muscles and is defined as: (leg length (in m) - seat height (in m)) x body mass x acceleration of gravity x sit to stand repetitions / time (sit-stand) (in sec.)

    Measured: During pulmonary rehabilitation, approximately 14 days

Where is the study taking place?

The record lists 1 site in Switzerland. 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?

Number of repetitions in the 1-min STS test (time frame: During pulmonary rehabilitation, approximately 14 days). 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 NCT04579055, which also lists 5 linked publications.

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 21 Jul 2021.
