A new low-cost system for rehabilitation of the impaired upper limb for stroke survivors is presented. A computer game was developed specifically for this purpose and the user's impaired upper extremity is tracked using a downward-pointed Kinect, an inexpensive motion capture system commercially available from Microsoft. A Kalman filter was implemented to reduce data jittering. Patients are required to move their impaired arm, sliding it on top of a transparent support, in order to play the game. The game is personalized to the patient through specific settings that adapt to the patient's range of motion and motor control at the start of the game as well as performance during the game. The final score is proportional to the arm's movement speed. A feasibility study was carried out with one stroke survivor. The game was played for ten days and usability surveys were answered before and after the study. The patient was engaged with the game, found it easy to understand and reported willingness to use it in the home environment and enjoyment of the use in the clinic.

Human gait is an important indicator of health, with applications ranging from diagnosis, monitoring, and rehabilitation. In practice, the use of gait analysis has been limited. Existing gait analysis systems are either expensive, intrusive, or require well-controlled environments such as a clinic or a laboratory. We present an accurate gait analysis system that is economical and non-intrusive. Our system is based on the Kinect sensor and thus can extract comprehensive gait information from all parts of the body. Beyond standard stride information, we also measure arm kinematics, demonstrating the wide range of parameters that can be extracted. We further improve over existing work by using information from the entire body to more accurately measure stride intervals. Our system requires no markers or battery-powered sensors, and instead relies on a single, inexpensive commodity 3D sensor with a large preexisting install base. We suggest that the proposed technique can be used for continuous gait tracking at home.

The US military and Microsoft are trying to simplify therapy for injured soldiers Microsoft microsoft.com Microsoft and the United States Air Force are testing the Kinect as part of a home therapy physical suite program for injured soldiers. Microsoft will also be discussing the project with Army's Communications-Electronics Research, Development, and Engineering Center, according to reporting by Defense News. The Kinect hardware is partnered with Infostrat's ReMotion360 physical therapy software.

“Microsoft is committing R&D and marketing resources to ensure that the [Defense Department] community is aware of the capabilities of the product, as well as the breadth of our partner community, which includes the system integrators,” said Microsoft director of public sector solutions Phil West. “The targeted scenarios include therapy-related functions, but they also span training and simulation, interactive user interfaces, and so on.”

The project is part of Microsoft's efforts to use the Kinect outside of the consumer market, with focuses on enterprise and public sector utilization. Other defense-related organizations, including Defense Advanced Research Projects Agency, the Joint Improvised Explosive Device Defeat Organization, Army Medicine, the Navy's Bureau of Medicine, Lockheed Martin, SAIC and CACI, have looked at the inexpensive motion-tracking capabilities of the Kinect for different purposes.
