Tech4Pod Presents an Online Lecture:

Home Based Technology for Children with Impaired Upper Extremity

Dr. Yi-Ning Wu presented a lecture on home-based technology therapy for children with impaired upper extremity. Electronics and video games are used as motivators for therapy. Children with hemiplegic cerebral palsy often neglect the impaired arm, which can lead to decreased brain excitability and hand mobility. Due to limited clinic visits in current rehabilitation practice, the program Massed-practice AT Home (MATH) was developed, incorporating electronics, video games and advanced software programming to create more effective outcomes in therapy.

Seminar: A Predictive Energy-Bounding Approach for Haptic Teleoperation

Presenter: Prof. Jeha Ryu
Department of Mechatronics/Medical Systems Engineering Gwangju Institute of Science and Technology
Gwangju, Korea (South)

In this seminar, a predictive energy-bounding approach (EBA) was presented for transparent and stable haptic bilateral teleoperation for any time delay and data losses as well as for any uncertain environments over any network. The proposed scheme (termed as Predictive EBA) combines the bilateral EBA with Smith predictor (SP) architecture in the master site which predicts the slave (site) states on the master site to improve the force tracking transparency using the SP while EBA guarantees robust stability against any uncertainties.

Quantitative and qualitative transparency analyses of bilateral EBA and Predictive EBA show significant improvement in magnitude and phase of feedback force and consequently the perceived impedance if the slave/environment dynamics is well known.

The proposed predictive EBA also allows any feedback signals such as measured contact forces/torques, position error based forces, and obstacle avoidance forces from slave sites. Experimental results show the effectiveness of the proposed predictive EBA for any large time delay while keeping robust stability of the overall system.

Tech4POD Presents an Online Lecture:

Title: Home-based technology for children with impaired upper extremity
Speaker: Dr. Yi-Ning (Winnie) Wu
Host: Li-Qun Zhang

1-2pm CST on February 15, 2013

Abstract: Cerebral palsy (CP) is one of leading causes of childhood disability. Children with CP have impaired motor or sensory function or both about one limb, one side of body or four limbs depending upon the lesion site and size of the brain. Children with one side of body involved are categorized as hemiplegic CP. A child with hemiplegic CP often only uses the unimpaired arm for daily activities and disregard his/her less-able arm, which is potentially valuable. This observed developmental disregard is similar to the learned non-used seen in the adult stroke. Decreasing usage of impaired hand leads to further reduction in excitability of injured brain. This connection sets off a deleterious circle of decreasing brain excitability and hand mobility. Massed-practice of the impaired hand is thought to facilitate use-dependent neuroplasticity and promote functional recovery of hand use. However, solely relying on the conventional rehabilitation is not practical to reach the effective intensity of massed-practice because of limited clinic visits due to health care cost, time commitment, travel inconvenience, etc. To overcome the limitation, we have been developing a low-cost home-based therapy system which could deliver and monitor Massed-practice AT Home (MATH) beyond the clinical setting. Our system, consisting of a standard computer, a small hand-held controller, an arm rest, a camera and various video games, capitalizes on cheaper electronics, advanced software programming and using video games as motivators. In this talk, I will share the findings and experience based on our earlier home-based approach and the currently evolved approach. I will also present the preliminary data on how the children responded to our new system. Our system can potentially have great impact on the neurorehabilitation for both children and adults with movement disorders.
