Abstract Resume

Background: The Range of Motion (ROM) Is Considered an Important Parameter of Training Prescription and Physical Assessment, like as Classifications Rules and Regulations for
Classification in Paralympic Sport by Ensure that Athletes Compete Equitably with each other. The Purpose of Classification is to Minimise the Impact of Eligible Impairment Types on the Outcome of
Competition, so that Athletes who Succeed in Competition are Those with Best Anthropometry, Physiology and Psychology and who Have Enhanced them to Best Effect. The Focus of this Work was to Build An
Innovative Tool for Measuring the Amplitude of Arm Movement, Called Rehabgesture.


Methods: In the Development of the Rehabgesture Tool, We Used the Gesture Recognition Sensor Kinect, and the Concepts of Natural User Interface (NUI) and Open Natural Interaction
(Openni). Rehabgesture Application was Developed in a Multidisciplinary Study in The Laboratory Of Visualization, Immersive, Interactive And Collaborative (Laviic), Computer Science Department, and
Was Approved by the Ethics Committee on Human Research Under the Process Number – CAAE 11319712.4.0000.5504, Supported by the Center for Science and Technology / Federal University of São Carlos.


Results: Rehabgesture Can Measure and Record the Range of Motion (in the Coronal Plane) from 0° Extension to 145º Flexion of the Elbow Joint, and from 0° Aduction to 180° Abduction of
the Glenohumeral (Shoulder) Joint, Leaving the Standing Position. The Movement of Abduction Goes Through Three Stages: 1st Stage - 0º to 60º is Performed Solely by the Shoulder Joint; The 2nd Stage -
60º to 120º is Performed by the Shoulder Joint with Participation of Scapulothoracic Joint and The 3rd Stage - 120º to 180º Degrees that Combines Trunk Inclination and the others Joints Described
above. Data are Recorded at 30 Hz (Frames per Second) and Separated by Joint (Shoulder / Elbow) and Side (Right / Left). The Proposed Tool has Application in the Fields of Training and Physical
Evaluation of Professional and Amateur Athletes in Clubs and Gyms, and May Have Application in Rehabilitation and Physiotherapy Clinics for Patients with Compromised Motor Abilities.


Conclusions: Rehabgesture Represents a Low Cost Solution to Measure the Movement of the Upper Limbs, and to Stimulate the Process of Teaching and Learning In Disciplines Related to
the Study of Human Movement, such as Kinesiology. From the Data Acquired, by Rehabgesture, Creating Charts is Possible to Compare Differences Between the Movement for the Same Joint (Right Vs. Left)
or Among Patients Undergoing the Same Therapy, Allowing Health Professionals (Kinesiology Experts) to Create a Database. However, More Studies are Necessary to Indicate the Use of Rehabgesture Tool in
Scientific Research on Human Movement Analysis.
