The current study is designed to evaluate neck movements performed according to the VRP-Clinic software, and to verify that they promote physical activities that correspond with physical rehabilitation.

The study will take place at Shaare Zedek Medical Center (SZMC). The study will include a single visit.

Each subject will put on the VR headset and perform a series of neck movements guided by graphic instructions appearing in the VR environment. The session will be recorded with a video camera which will subsequently be viewed and evaluated by clinicians. The clinicians will identify each movement seen on the video from a predefined list and determine if such a movement is recommended as part of a rehabilitation training program.
