Significant research has been done on recognizing the daily activities using acceleration data but few works have focused on classifying the movements comprising an activity due to the shorter time scales of the movements compared to that of an activity. Recognizing the individual movements within an activity can help improve the activity recognition on the whole by using the extra information from...
Rehabilitation of the sit-to-stand movement may be made more effective by providing feedback about the underlying coordination pattern rather than movement parameters. Principal component analysis (PCA) was used to identify coordination modes in sit-to-stand. An algorithm of movement parameters was used to create a visual feedback signal representing this coordination mode in real-time.
An interactive software assistant (SimScript) has been developed to help in the design of neuromuscular tests and in the analysis of data gathered from these tests. The tool is based on the Kinematic Theory of rapid human movements and its Sigma-Lognormal (SigmaLambda) model. It allows the manipulation of the movement kinematics using analytical expressions. Although the project is still exploratory,...
For elderly and or physically disabled people who have lost their body functioning of motions due to geriatric disorders, and/or disease processes including trauma, sports injuries, spinal cord injuries, occupational injuries, and strokes, we have been developing a 3 DOF mobile robotic exoskeleton for rehabilitation and for assisting motion of elbow and shoulder, since human shoulder and elbow motions...
A low cost portable acquisition system for monitoring and processing human body segment movements is presented It is equipped with 32 multiplexed input channels, each one linked to an external 2 axis MEMS accelerometer. Input signals from sensors are converted into a digital form by a 10 bit analog to digital converter and transmitted via Bluetooth technology to a remote PC. The instrument is battery...
Skeletal deformity is an important characteristic of osteogenesis imperfecta (OI). To study the influence of deformity in stress/strain distribution, a finite element analysis (TEA) of the femur during physiological loading was developed. The diaphysis was altered mathematically to reflect different clinical deformities of OI. Joint reaction and muscle forces were adapted from the literature to reproduce...
Virtual reality (VR) has the potential to offer experiences which are engaging and rewarding. In VR, the focus is shifted from the person's efforts in producing a movement or completing a task to that of interaction with the virtual environment. We have found that participants place value and meaning on and enjoy the activities programmed. Virtual reality interventions have been shown to improve cognitive...
