Multi-sensory, Non-Invasive Whole-Body Range of Motion Detection for Quality of Improvement Measurement


·  Goniometers are manual devices for measuring joint Range of Motion (ROM) and hence are not very accurate.

·  Minor recovery in ROM in patients cannot be measured using goniometers.

·  Use of goniometers requires the help of a trained person.

·  A patient needs to get an appointment at the clinic to measure her improvement with a goniometer.

·  A patient seeing day-to-day improvement will be encouraged to do more exercise and recover quickly. This cannot be done with a goniometer due to the above mentioned reasons.


·  We have developed a simple software application that can use devices like Kinect and Leap motion to measure joint ROM.

·  The Kinect device can measure 25 joints in the human body 60 times per second while the Leap device can measure all hand joints at 30-200 times per second.


•  ROM can be detected easily anytime without the help of the therapist.

•  Patients can know their improvement pace through detailed measurements.

•  Gamification of the technology can lead to immersive environments for providing physiotherapy to remote patients.

•  Motion detection facility provided by the sensors can be used to detect gestures which can in turn be used to perform different chores around the house using a computer and smart home appliances, making daily life activities easier for disabled people.

•  The large amount of data collected through these devices can be used to study and discover new recovery metrics.

•  The 3D skeleton displayed on the screen allows the user to explain to the patient the exact details of her disability which may help her in focusing on the right group of muscles to perform the exercise properly.

•  The 3D skeleton can be used for pedagogical purposes.
