[0045] figure 1 , Figure 2A , Figure 2B , Figure 3A , Figure 3B and Figure 3C Different views of the hand rehabilitation device 100 according to a possible embodiment of the invention are shown. Device 100 is universal, meaning it can be configured for rehabilitation of either the right or left hand. The configuration shown in these figures is a right-handed configuration, but it can simply be switched to a left-handed configuration, which will be explained later in this article. The device 100 may be attached to another device or device, for example to a tool robot, manipulator or arm support (eg a support fixed to a table), or directly to a user's arm. It also works as a handheld.

[0046] The portable device 100 is configured to be grasped by the hand to be trained such that the palm, fingers and thumb (inside of the hand) surround the grasped device 100 . In this particular embodiment, the structure 110 will be grasped by the right hand, as Figure 2B shown. ...

Abstract

A hand rehabilitation device (100) comprises: at least one first support (124) configured to support the thumb of a hand, wherein said at least one first support (124) is designed to perform a flexion / extension movement for rehabilitating said thumb, said flexion / extension movement being actioned by a first transmission mechanism to which the at least one first support (124) is connected; at leastone second support (120, 121, 120B) configured to support the index finger of said hand, wherein said at least one second support (120, 121, 120B) is designed to perform a flexion / extension movementfor rehabilitating said index finger, said flexion / extension movement being actioned by a second transmission mechanism to which the at least one second support (120, 121, 120B) is connected; at leastone third support (122, 123, 122B) configured to support the three remaining fingers-middle ring, and little fingers of said hand, wherein said at least one third support (122, 123, 122B) is designedto perform a flexion / extension movement for rehabilitating said three remaining fingers, said flexion / extension movement being actioned by a third transmission mechanism to which the at least one third support (122, 123, 122B) is connected. The first, second and third transmission mechanisms are actuated by at least one motor, and the three flexion / extension movements of said at least one first support (124), said at least one second support (120, 121) and said at least one third support (122, 123) are independent from each other.

Description

technical field [0001] The present invention relates to the field of devices for the rehabilitation of damaged limbs, in particular devices for the rehabilitation of damaged hands and fingers. Background technique [0002] Finger function may be lost or damaged due to neurological damage such as stroke, spinal cord injury, traumatic brain injury, or Parkinson's disease. For example, a stroke may cause paralysis on one side of the body. Examples of impaired finger function are poor finger extension, poor finger coordination, loss of finger independence, poor grasping or manipulation, and inability to control a constant grip. Partial (or even complete) restoration of impaired function is possible due to the brain's limited ability to reorganize damaged neural connections. [0003] Active devices exist for hand rehabilitation including finger rehabilitation. This type of rehabilitation is usually designed to stimulate recovery by performing repetitive movements that involve ...
