About this study
This study was designed as a two-arm, parallel-group randomized controlled trial with a 1:1 allocation ratio. A total of 55 office workers were randomly allocated to an experimental group (n = 28) or a control group (n = 27). The experimental group participated in a four-week active break program, while the control group received no intervention. Participants in both groups were instructed to maintain their usual daily activities, ergonomic setups, and health routines throughout the study.
The study aimed to investigate the effects of a brief daily active break program on subjective musculoskeletal pain and spinal mobility in office workers. Assessments were conducted at baseline, after two weeks, and after four weeks to evaluate changes over the study period.
Read the detailed description
Previous research on workplace active breaks and microbreaks has primarily focused on subjective symptom questionnaires, with less emphasis on objective measurements of spinal range of motion. Furthermore, previously investigated programs have often involved activity sessions lasting ten minutes or longer, which may be difficult to incorporate into a typical working day. The present study examined whether a brief, once-daily active break program could produce measurable changes in subjective musculoskeletal pain and spinal mobility.
A total of 55 office workers were recruited through convenience sampling and randomly allocated to an experimental group (n = 28) or a control group (n = 27). The experimental group participated in the active break program for four weeks, whereas the control group received no intervention. Participants in both groups were instructed to maintain their usual daily activities, ergonomic setups, and health routines throughout the study.
Data collection included an online questionnaire and objective measurements of spinal mobility. All spinal mobility measurements were performed by a single blinded assessor. One measurement trial was conducted for each test, side, and assessment session, with values recorded to the nearest 0.1 cm. Repeated trials and averaging were not performed, and intra-rater reliability was not directly assessed.
To minimize potential immediate effects of exercise on spinal mobility measurements, participants in the experimental group were instructed to perform the active break only after the assessments scheduled for the second and third measurement sessions.
Daily activity behaviors were assessed using the Daily Activity Behaviors Questionnaire (DABQ), which evaluates sleep, sedentary behavior, light-intensity physical activity, and moderate-to-vigorous physical activity during the preceding seven days. The questionnaire was completed through an online survey platform accessed using a QR code. Each participant was assigned a unique identification number to link questionnaire responses with objective measurements while maintaining participant anonymity.
Adherence to the intervention was monitored using a daily online log. Participants in the experimental group recorded both days on which the active break was completed and days on which the intervention was not completed.
The control group served as a comparison group for changes in spinal mobility over the four-week observation period without the active break intervention.
Institutional approval was obtained from all participating organizations before study initiation. Written informed consent was obtained from all participants. Information regarding study procedures, the voluntary nature of participation, and the right to withdraw at any time without providing a reason or experiencing negative consequences was provided before enrollment.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Active BreakOther
To ensure correct and safe execution of the exercises, the exercises were demonstrated and performed together with the participants during the initial active break, allowing them to master the techniques; in addition, they received a leaflet with written instructions, which further reduced the likelihood of incorrect performance.
| Study group | Role | What they receive |
|---|---|---|
| No intervention group | No intervention | No intervention |
| Active break | Experimental | Active break Receives: Other: Active Break |
What is being measured
The primary outcome is the main question the study is designed to answer.
Pain assessment
Pain assessment using Visual Analoge Scale; 0 = no pain, 10 = very painful
Measured: Pain was assessed at the beginning and at the end of the 4-week active break program.
Secondary outcomes (1)
Spinal mobility results
Lumbal flexion, lateral flexion to the left and lateral flexion to the right were messured
Measured: At the beginning, after 2 weeks and at the end of 4 week protocol

Questions about this trial
What is this clinical trial studying?
A study testing Active Break in people with Musculoskeletal Pain and Flexibility, run by Julia Wegener at 1 site in Slovenia.
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 8 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 8 Oct 2026. 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 Slovenia. 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?
Pain assessment (time frame: Pain was assessed at the beginning and at the end of the 4-week active break program.). 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 NCT07865143, which also lists 10 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 8 Oct 2026; AzTrials last refreshed its copy on 6 Nov 2026.
