About this study
Official title: Acute Effects of Spinal Manipulation on the Neuromuscular Performance of Amateur Cyclists: Pilot Study
The present study aims to assess the effects of spinal manipulation therapy on neuromuscular performance.
Read the detailed description
The present study will follow a parallel, pre-post design. The aim will be to determine the acute effects of spinal manipulation therapy (SMT) on different neuromuscular properties of recreational cyclists. Specifically, the investigators will measure the maximum force production capacity and muscle activation of the knee extensors concomitantly during a maximal voluntary contraction, as well as the maximum and mean power attained during a Wingate cycling test (i.e., 30 seconds 'all out'). Participants will undergo the tests on two different occasions separated by at least 48 hours and a maximum of 2 weeks. The same tests will be conducted in both testing sessions, but participants will be randomly assigned into two groups (sham or actual SMT) immediately before the second testing session.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Spinal manipulative therapyProcedure or surgery
Also called Chiropractic manipulation, Spine thrust manipulation
Participants in the actual spinal manipulative therapy group will be assessed through the activator basic method protocol. SMT will be performed with an Activator IV (Activator Methods International, Phoenix, AZ) setting the force at level 3 for the low thoracic spine (T7-T12), and level 4 for the lumbar spine and pelvis.
Sham spinal manipulative therapyOther
Participants in the sham SMT group will undergo a protocol identical to the actual one, with the exception that a sham mechanical thrust (force set at level 0) will be delivered to the targeted areas. In the force level 0 no excursion of the stylus occurs, but the instrument produces the same clicking sound as in the actual SMT condition
| Study group | Role | What they receive |
|---|---|---|
| Sham spinal manipulation | Sham comparator | Participants in the 'sham' group will receive a sham mechanical thrust (force set at level 0) instead of an actual one. In the force level 0, no excursion of the stylus occurs, but the instrument produces the same clicking sound as in the actual SMT condition. Therefore, the subject does not distinguish between intervention or placebo. Receives: Other: Sham spinal manipulative therapy |
| Actual spinal manipulation | Experimental | Participants in the actual actual spinal manipulative therapy (SMT) group will be assessed through the Activator basic method. SMT will be performed with the Activator IV Adjusting Instrument (Activator Methods International, Phoenix, AZ) varying the force level depending on the adjusted segment. Receives: Procedure: Spinal manipulative therapy |
What is being measured
The primary outcome is the main question the study is designed to answer.
Maximal force
Peak force registered during an isometric maximal voluntary contraction of the knee extensors.
Measured: On the control session and on the intervention session (immediately after the sham or actual SMT procedure)
Voluntary activation
Electromyographic activity of the vastus lateralis muscle registered during an isometric maximal voluntary contraction of the knee extensors.
Measured: On the control session and on the intervention session (immediately after the sham or actual SMT procedure)
Peak power
Peak power registered during a 30-second Wingate anaerobic cycling test
Measured: On the control session and on the intervention session (immediately after the sham or actual SMT procedure)
Mean power
Mean power registered during a 30-second Wingate anaerobic cycling test
Measured: On the control session and on the intervention session (immediately after the sham or actual SMT procedure)
Timeline
From the start of the study to its completion; the mark is today. Estimated dates are the sponsor’s plan.
- First posted12 Apr 2019
- Study startJun 2022 (estimated)
- Primary completionJul 2022 (estimated)
- Study completionOct 2022 (estimated)
Why it stopped: In the first tests the force meter gave an error and all the records were lost. Then came the COVID-19 pandemic. At this time we are unable to finish the study. We hope to be able to complete it by the middle of next year.

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 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: withdrawn, as of the sponsor's last update on 13 May 2024. 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. Some participants in this study may receive a placebo. 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 withdrawn before enrolling participants, so there are no results.
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?
Maximal force (time frame: On the control session and on the intervention session (immediately after the sham or actual SMT procedure)). The study lists 4 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 NCT03913546, 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 13 May 2024; AzTrials last refreshed its copy on 6 Nov 2026.
