FORCED GRASPING AND GROPING

Improvement and Neuroplasticity after Combined Rehabilitation to Forced Grasping

The grasp reflex is a distressing symptom but the need to treat or suppress it has rarely been discussed in the literature. We report the case of a 17-year-old man who had suffered cerebral infarction of the right putamen and temporal lobe 10 years previously. Forced grasping of the hemiparetic left upper limb was improved after a unique combined treatment. Botulinum toxin type A (BTX-A) was fi...

Genome Evolution: Groping in the Soil Interstices

Centipedes are a very old lineage of terrestrial animals. The first completely sequenced myriapod genome reveals that the blind centipede Strigamia maritima has no gene for light-sensory proteins, lacks the canonical circadian clock and possesses unusual features related to chemosensory perception.

3-Fingered Hand an Unknown Objects by Groping

This paper addresses the development of a three-fingered hand and discusses a strategy for grasping unknown objects by groping. In the former part of the paper, the design of the developed robot hand is presented. The robot hand has thumb, index finger and middle finger with a total of eight degrees-of-freedom. The location of thumb is designed considering opposability of human hand. Eightyseve...

People Groping by Spatio-Temporal Features of Trajectories

This paper proposes a method for detecting people groups from their trajectory data. This grouping is applied to each pair of people. The trajectories of the pair are featured by their spatio-temporal relationships such as a distance and velocities. The features are classified to either of “group” or “non-group” by a discriminative classifier. In contrast to previous features, the proposed feat...
