About this study

Official title: Physical Deconditioning and Non-Specific Low Back Pain: the PHYDEL Study. A Prospective Study in a COVID-19 Positive Cohort

The purpose of this study is to take advantage of cohorts of patients followed for Coronavirus Disease 2019 (COVID19) expected to present poor physical fitness as the consequence of COVID19 to explore the relationship between physical fitness and low back pain (LBP). Level of physical fitness will be measured at baseline and incidence and intensity of LBP will be recoreded over 1 year.

Read the detailed description

Non-specific low back pain (LBP) is the worldwide number one cause for disease related years lived with disability. It is frequently assumed that a low physical fitness is a major risk factor for acute LBP as well as a factor for chronic LBP. However only few prospective observational study have been conducted.

The purpose of this study is to take advantage of cohorts of patients followed for Coronavirus Disease 2019 (COVID19) expected to present poor physical fitness as the consequence of COVID19 and assessing level of physical fitness and both incidence and intensity of LBP over a 1-year period.

The study aims to determine if a poor physical health, as measured by 6 minutes walk test (6MWT) and 30''seconds sit to stand test (30''STS), is a risk factor for LBP occurrence and for chronic LBP Secondary objectives aim to explore the respective weight of physical factors (i.e. physical fitness, BMI, smoking, physical activities) and psychological factors (i.e. depression, anxiety, catastrophism, fear-avoidance) on the occurrence and severity of LBP.

According to the literature, we expect that in the physically healthy population, 15% will developed back pain; whereas in the population in poor physical health the incidence at 1 year will be 30%. If alpha error is set at 0.05 then 236 patients are required to have a 80% chance to confirm our hypothesis. In order to account for drop out, and considering that the risk of drop out is high in this type of non-interventional study 350 persons will be recruited. Note that this amount of persons should yield approximately 70 persons with low back pain, which allow up to 7 independent variable in a logistic or cox regression. This is based on the rule of at least 10 events (low back pain) per variable.

What is this clinical trial studying?

An observational study of Low Back Pain, Mechanical, run by University Hospital, Geneva at 1 site in Switzerland.

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 3 inclusion and 3 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: stopped early, as of the sponsor's last update on 9 Nov 2022. 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 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 was stopped early (reason given: Grant not allowed). Results are not available in the source record.

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?

1-year incidence of LBP (time frame: 1 year). The study lists 2 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 NCT04990518, which also lists 9 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 9 Nov 2022.
