Haptic Device for Capturing and Simulating Hand Manipulation Rehabilitation

Capturing Human Hand Kinematics for Object Grasping and Manipulation

Continuous passive motion device for hand rehabilitation.

Prototypes have been designed and manufactured for a lightweight portable device which continually moves all the joints of the hand passively through a range of motion. Inflatable bag modules in the palm of the hand are ganged together to create the required range of motion. A battery-operated air pump cycles compressed air to the modules. Initial clinical experience with patients who have flex...

Visual Feedback Manipulation for Hand Rehabilitation in a Robotic Environment

The ultimate goal of this research is to manipulate visual feedback in order to make robotic therapy more effective than traditional human-assisted and robotic rehabilitation. Toward this end, this thesis examines the limits and effects of visual feedback distortion, a type of visual feedback manipulation, in a robotic environment. Visual feedback establishes a metric of performance for a given...

Reliability of the Modified In-hand Manipulation Test and the Relationship Between In-hand Manipulation and Handwriting

Objectives: This study aimed at analyzing the test-retest and interrater reliabilities of the Test of In-Hand Manipulation-Modified (TIHM-M), as well as the relationship between in-hand manipulation and handwriting. Methods: We administered the TIHM-M twice, two days apart, and the Beknopte Beoordelingsmethode voor Kinder Handschriften (BHK) - Concise Assessment Method for children’s handwriti...

Haptic Camera Manipulation: Extending the “Camera In Hand Metaphor”

Many applications that support force feedback make use of a haptic device (such as the PHANToM) used for pointing operations, combined with a second device mainly used for navigation (such as a SpaceMouse). In our former research project we introduced the Camera In Hand Metaphor in which we use the PHANToM device for camera manipulations. This allows us to eliminate the second device and hence ...
