Hemophilic Knee Arthropathy Virtual Reality (hemophilia)

Adolescents With Hemophilic Knee Arthropathy Can Improve Their Gait Characteristics, Functional Ability, and Physical Activity Level Through Kinect-based Virtual Reality: a Randomized Clinical Trial

This study intended to examine the effect of a physical rehabilitation program incorporating Kinect-based virtual reality on gait characteristics, functional ability, and physical activity level in adolescents with hemophilic knee arthropathy.

The usage of virtual reality in clinical practice as an alternative for conventional procedures has recently sparked the interest of health professionals. Virtual reality is a type of computer technology that provides simulated sensory feedback to allow children to participate in activities and events that are comparable to those they could face in real life. It can be used therapeutically to enhance strength, range of motion, coordination, mental concentration, problem solving, decision making, balance, and gait.

Each participant was instructed to walk bare feet with a comfortable, self-selected speed along a 10-meter walkway while the trajectories of reflective markers and forces were respectively recorded through 12 optoelectronic cameras (Vicon Motion Systems Ltd., Oxford, UK) with a 120-Hz sampling rate and two force plates at 1000 Hz.
