Muscle HypertoniaNCT05685563
Load During Sweep Rowing and the Influence on the Posture
An observational study of Muscle Hypertonia and Postural Scoliosis, run by Charles University, Czech Republic at 1 site in Czechia.
Trial summary
The aim is to assess the influence of asymmetric training on the locomotor system in sweep rowers. To analyse possible changes objectively, the axial position of the hull will be assessed using Moiré topography, and the symmetry of foot loading will be monitored with a pedobarograph.

About this study
Official title: Influence of Regularly Repeated Asymmetric Load on the Locomotor System in Sweep Rowers
The aim is to assess the influence of asymmetric training on the locomotor system in sweep rowers. To analyse possible changes objectively, the axial position of the hull will be assessed using Moiré topography, and the symmetry of foot loading will be monitored with a pedobarograph. Furthermore, the Visual Analog scale and Cluster of Laslett will determine whether an asymmetric load can provoke pain in the lumbar region or cause a blockage in the SI joint. In the experimental study, there will be three different groups of participants. Selected sweep rowers will make the first study group. The second group will consist of scull rowers, and the last control group will consist of people with no experience with rowing. The selected participants will undergo the first measurement at the turn of the spring and summer seasons when intensive preparation for rowing competitions begins, in which sweep rowers train mainly on water and asymmetrically. The measurement results in the three groups will be further compared with each other to evaluate whether statistically significant differences can be found.
Read the detailed description
Methods: 21 sweep rowers, 20 scull rowers and 23 non-rowing peers were enrolled on the study of this diploma thesis. Each subject was assessed using DIERS formetic 4D and DIERS pedoscan devices. Additionally, participants in each group were assessed by FAIR test, Cluster of Laslett, trigger point palpation of the m. piriformis and Visual analogue scale were used to assess pain intensity in the lumbar region.

Questions about this trial
What is this clinical trial studying?
An observational study of Muscle Hypertonia and Postural Scoliosis, run by Charles University, Czech Republic at 1 site in Czechia.

The record lists 1 site in Czechia. 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?
Rotation deviation of the trunk at the level of L3 vertebrae and sway area of COP (time frame: one-time measurement). The study lists 5 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 NCT05685563, 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 17 Jan 2023.
