**4. Conclusion**

The results of this study show that the managed rehabilitation in a closed kinetic chain has demonstrably better results compared to the therapy conducted in an open kinetic chain. The similarity principle, which integrates functional movement patterns into patients´ activities of daily living, is considered the key element. The patients agree that if the movement therapy is aimed at improvement of specific motion skills applicable in ADL, their motivation to perform the exercises is higher. Correctly set up CKC therapy leads to reduction of subjective perception of pain, which has already been proved in various studies. The results of our study show not only significant improvement of functional skills of patients in ADL but also significant reduction of a number of postural errors concerning standing positions and locomotion.

Patients undergo total hip joint replacement in particular in order to improve the quality of their life. On the grounds of our study's results it can be stated that the ACT based therapy, compared with the open kinetic chain therapy, influences the quality of the patients´ life after total hip joint replacement in a significant way.
