About this study
Official title: Effects of Traction Mobilization Techniques on Knee Joint Position Sense and Biomechanical Properties of Knee Joint Tissues
The aim of this study is to evaluate the effects of traction mobilizations on position sense in the knee joint and on the biomechanical properties of the knee joint tissues.
- Conditions
- Manual Therapy, Knee
- Being tested
- Pulse traction, Continuous traction, Sham therapy
- Keywords
- knee, manual therapy, healthy people, MyotonPRO
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Pulse tractionOther
The subjects underwent impulse traction of the knee joint in the second degree according to the Kaltenborn concept.
Continuous tractionOther
The subjects underwent continuous traction of the knee joint in the third degree according to the Kaltenborn concept.
Sham therapyOther
The therapist did not use traction force, the knee joint was kept in a flexed position of 40 degrees.
| Study group | Role | What they receive |
|---|---|---|
| Control group | No intervention | Participants in this group did not undergo any therapy. |
| Pulse traction group | Experimental | Participants assigned to this group underwent second degree impulse traction of the knee joint according to the Kaltenborn concept. Receives: Other: Pulse traction |
| Continuous traction group | Experimental | Participants assigned to this group underwent continuous traction of the knee joint in the third degree according to the Kaltenborn concept. Receives: Other: Continuous traction |
| Sham therapy group | Sham comparator | The therapist did not use traction force, the knee joint was kept in a flexed position of 40 degrees. Receives: Other: Sham therapy |
What is being measured
The primary outcome is the main question the study is designed to answer.
Joint position sense
A passive-active test will be used to assess the joint position sense. The parameters will be measured angular position (degree of flexion) of the knee joint in the position passively set by the researcher and in the position actively recreated by the participant in both knee joints.
Measured: Before intervention and immediately after intervention
Secondary outcomes (5)
Biomechanical properties of knee joint tissues: Frequency
The values of knee joint tissue parameters will be assessed by using MyotonPro
Measured: Before intervention and immediately after intervention
Biomechanical properties of knee joint tissues: Stiffness
The values of knee joint tissue parameters will be assessed by using MyotonPro
Measured: Before intervention and immediately after intervention
Biomechanical properties of knee joint tissues: Relaxation
The values of knee joint tissue parameters will be assessed by using MyotonPro

Questions about this trial
What is this clinical trial studying?
A study testing Pulse traction and Continuous traction in people with Manual Therapy and Knee, run by The Jerzy Kukuczka Academy of Physical Education in Katowice at 1 site in Poland.
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 5 inclusion and 6 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: under way, not looking for participants, as of the sponsor's last update on 21 Feb 2025. 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 Poland. 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?
This study is still under way. Results are not available in the source record yet.
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?
Joint position sense (time frame: Before intervention and immediately after intervention). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 Feb 2025.
