8 sessions of VR therapy over 4 weeks (each of them 20 minutes long). As a virtual reality source, VRTierOne device (Stolgraf®) were used. Thanks to using head mounted display and the phenomenon of total immersion VR therapy provides an intense visual, auditory and kinesthetic stimulation. It can have a calming and mood-improving effect or help the patients recognize their psychological resources and motivate to the rehabilitation process. In the virtual therapeutic garden there are a rich set of symbols and metaphors based on Ericksonian Psychotherapy approach. The most important is the Garden of Revival which symbolizes the patient's health. It used to be full of life and energy, now it is neglected, requires work to be revived. In the therapeutic process day by day, the therapist tells the patient a symbolic story about his/her situation.

The experimental group will receive eight sessions of audio recording based on the Non-Sleep Deep Rest (NSDR) concept during the 4-week rehabilitation program. Each 20-minute session is conducted in a quiet setting using noisecancelling headphones. The recording guides patients through a structured body scan, directing attention sequentially to specific body regions and prompting active muscle relaxation. Body scanning is combined with mindful breathing to deepen relaxation and attenuate sympathetic nervous system activity. Therapeutic suggestions focus on reframing overload versus relief, letting go versus holding on, and balancing action with awareness. The intervention aims to enhance psychological resilience and support the balance between the sympathetic and parasympathetic parts of the autonomic nervous system. The protocol is non-invasive, safe, and feasible for routine clinical use.

Conventional rehabilitation follows standard postoperative protocols after hip or knee arthroplasty. The 4-week program includes five weekly sessions. Gait training is conducted in hospital corridors under physiotherapist supervision, using assistive devices as needed (crutches, walkers). Daily therapy includes 120 minutes of kinesiotherapy (general exercises and gait training), 30 minutes of ergotherapy to improve functional independence, and three individualized physical therapy procedures (laser therapy, magnetic therapy, or electrotherapy) tailored to patient needs.
