Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Interventions is basically an exercises with resistance of the lower limbs in closed biokinematic chains, performed with modified "Leg-press" device. This kind of device allows only movement of extension and flexion of lower limbs against resistance - in this specific device (TELKO, manufactured/ distributed byACX/Technomex, Poland) resistance is created from elastic tubing. The only exercise performed will be flexion/ extension of lower limbs in closed kinematic chain made simultaneously for both limbs. The device uses virtual reality visual games to maintain patient focus in training and control parameters like force distribution between left/ right leg. The modification from standard training is due to active correction of the position of the feet and the axis of the lower limbs performed by the strength of the patient's own muscles, against the force disturbing this setting towards the valgus of the knees. The disturbing force will be realized through an elastic band (medium strength). The control of the position of the feet and the axis of the lower limbs will be performed with the use of biofeedback phenomenon and additional controls ( two on upper lowel leg, responsible for lower legs axis, and two on foot, responsible for keeping correct position / pressure of the foot).
The exercises will last 15 minutes daily, with resistance and fatigue desribed by the patient as moderate to heavy but pleasant (3 to 5 in ten point Borg Scale). This exercise will be performed individually, as we have only one such device.
As every participant will have individual account on the device software, report from every training session will be recorded and used for control of attendance and participation in training session.
Speed of excercise - according to patient possibilities, but with instructions that primary goal is to perform the exercise correctly (according to attached controls described above) not speed or fatigue.
Excercises will be performed for 5 days between the initial and final assessment - to avoid effects of muscle strengtening, instead of motor contol effect.
Intervention will be delivered by Physiotherapist with active right to physiotherapy practice.
The research will be held at "Pod Tezniami" Health Resort and Physiotherapy center in Ciechocinek, Poland.
All patients will receive the patient's informed consent form to participate in the research, they will be informed in detail about the course of the research and that they can resign from participation at any time.

As every participant will have individual account on the device software, report from every training session will be recorded and used for control of attendance and participation in training session.
Speed of excercise - according to patient possibilities, but with instructions that primary goal is to perform the exercise correctly by patient own visual observation of lower limb axis

Summary
Brief summary
Bioethical comitee aproval was extended to the june of 2022 in attachment.

This approval is for wider range research, inckluding except described trial also assessment of effectiveness of Dynamic Taping for lower part of Spiral Line according to Myers.

Both interventions (excercises described in this registartion) and dynamic taping share the same inclusion/ exclusion criteria, recruitment method and outcomes.

Research are taken to confirm/ proof effects observed subjectively in clinical work on individual basis with dysfunctional patients.
