Abstract: Provided herein are control and monitoring protocols for a virtual or augmented reality environment provided to patients, and which enable a trainer to have real-time monitoring and control of the virtual reality environment. In various embodiments, a virtual environment is provided to a first user at a first location. Data (e.g., biometric data) is collected based on the first user's interaction with the virtual environment while engaging in a training protocol. A real-time mirrored view of the virtual environment is provided to a second user via a network. The data and one or more control tools are provided to the second user. The control tools are configured to adjust one or more parameters of the virtual environment. A selection of at least one of the control tools is received form the second user and the virtual environment is adjusted based on the selection.

Abstract: An extended reality-based system for dynamic assessment of upper extremity impairments is disclosed. A virtual environment is provided to a user. A target path is received. A sensory stimulus is presented to the user. Three-dimensional position information is determined for one or more body part defining a recorded path. A plurality of motion parameters corresponding to a user response to the stimulus are determined by: comparing the recorded path to the target path, determining a smoothness metric of the recorded path, determining starting coordinates and ending coordinates of the path, determining a first time period from presentation of the sensory stimulus to when motion of the one or more body part begins, and determining a second time period for motion between the starting coordinates and the ending coordinates. At least one index indicative of upper extremity impairment from the plurality of motion parameters.

Abstract: A virtual/augmented reality-based system for guiding patients through rehabilitation exercises and providing real time feedback is disclosed. In various embodiments the system, methods, and computer program products relate to guiding and measuring neck and shoulder motion, specifically protraction and retraction motions. A virtual reality environment includes a fixed object having a guidance feature and a moveable object having a complementary shape to the guidance features. Whether the fixed object is in a complimentary orientation to the movable object is determined. When the fixed object is in a complimentary orientation with the movable shape, an indication is presented to the user to perform a motion. A plurality of sensors determines a plurality of measurements relating to the motion of the user. Whether the fixed object is in a complementary orientation with the movable object is determined based on the plurality of measurements.

Abstract: Provided herein are methods of and computer program products for physical therapy using VR/AR, specifically, for guiding user motion for physiotherapy in VR/AR environments. In various embodiments, a virtual environment is provided to a user via a VR/AR system. An event marker is provided at a first location within the virtual environment. A position of the event marker is adjusted to a second location. Positional data is collected based on the user's interaction with the one or more event markers. The positional data is provided to a remote server via a network and a compliance metric is determined based on the positional data. When the compliance metric differs from a predetermined range, an adjustment is applied to the event marker. In various embodiments, a visual field of a user may be altered and the user guided to repeat a task to assess and/or monitor proprioception.
