Definitions

  • the present invention and method are framed in medical devices more specifically in a device related to assisted movements and passive movements of at least one joint and a method for calibrating the device to different anthropometric characteristics and ranges of movement.
  • the loss or abnormal motor control of the upper extremity generates difficulty or inability to perform activities of daily living such as dressing, bathing and eating.
  • Loss of motor control can be caused by neuromuscular conditions, spinal cord injuries, cerebrovascular accidents (CVA), or neurodegenerative diseases.
  • CVA cerebrovascular accidents
  • Another group of individuals corresponds to patients in the post-operative process of trauma surgeries or other surgeries.
  • a group of patients with options to rehabilitate are those who suffer Cerebrovascular Accident (CVA). Stroke represents one of the main causes of disability in elderly people, leaving as a consequence hemiparesis in 50% of patients and post-first-event spasticity in 20% of cases, increasing direct care costs 4-fold in the first year after stroke. Subjects with spasticity have a significant deterioration, a lower sensory-motor function, more pain, greater limitation to the ranges of movement and a decrease in sensitivity.
  • CVA Cerebrovascular Accident
  • Hemiparesis is the inability or difficulty in controlling one side of the body, making it difficult to perform activities of daily living such as dressing or grooming.
  • Spasticity is the involuntary contraction of a muscle, which causes stiffness in the joints and can cause pain to the person.
  • Another group are the devices that use pneumatic actuators or with other fluids. They are normally positioned on the dorsal surface, leaving the palmar surface free.
  • One of its drawbacks is the lack of control over which group of joints will be activated and the precision of its movements. If the actuator covers the middle and distal interphalangeal joint it will not be possible to just flex or extend the metacarpophalangeal joint.
  • An example is the invention of the application W02G192Q3732A1.
  • This device could be grouped with devices that base their mechanical concept on the use of the skeletal structure of the hand and fingers as the mechanical operating structure. These types of devices are usually lighter and more discreet in appearance than the devices of the first and second groups indicated.

  • the extension movements are actively generated by an actuator, running the risk of overextending the finger and causing damage to the patient, while the present invention eliminates this risk by using a passive actuator without sufficient force to cause damage to the user.
  • Another invention to highlight is the one presented in document CN208049296U. It is a glove with an area to accommodate the palm and covers to accommodate at least one finger and at least one external face of the cover for the finger has at least one fixing element, an actuation element with a rotary axis , on the same surface as the fixing element. A rope that at one end is fixed to the fixing element and at the other to the axis of rotation, which allows the rope to be wound or removed to adjust its length.
  • this device introduces the way of being able to adjust the length of the string for one finger, the invention does not allow it to be done independently for each finger, this is due to the fact that the actuation element is shared, so it does not solve the problem that present the different anthropometric measurements that can arise between different users.
  • the tensor or cable of the device of document CN208049296U is always fixed at the distal end of the finger sheath, which does not allow deciding whether to only mobilize the metacarpophalangeal joint, or metacarpophalangeal and proximal interphalangeal joint, or total finger joints.
  • this problem is combined with the problem of using a single actuator, since the tensioner travel difference between the different fingers will be greater depending on the number of transition pieces through which the turnbuckle passes. In this way, there is still a need for a device that allows adjusting the travel of the tensioner to configure the desired movements and that such configuration can be done independently for each finger.

  • the device uses one actuator to abduct the thumb and a second actuator to provide thumb flexion.
  • the device of patent SG179321A1 can be configured with passive actuators that apply a force opposite to that generated by the tensioner. In the event that the tensioner generates flexion, the passive actuator will apply an extension force and vice versa.

Abstract

Un dispositif mobilisateur d'articulation conçu pour produire des mouvements de flexion et d'extension de l'index, du majeur, de l'annulaire et de flexion, d'extension, d'abduction et d'adduction du pouce. Le dispositif comprend une interface de main, une unité électromécanique et une unité de transmission de mouvement. Chacun des cinq doigts se mobilise avec un extenseur relié à un actionneur et à un actionneur passif. Les mouvement d'abduction et de flexion du pouce se réalisent avec le même actionneur alors que l'adduction et l'extension se réalisent avec au moins un actionneur passif. Le dispositif peut comprend un support pour stabiliser la position du poignet et diriger les extenseurs. L'invention concerne en outre un procédé de calibrage d'amplitudes de mouvement et de mesures anthropométriques pour déterminer l'amplitude d'extension et de flexion (et d'abduction et d'adduction du pouce) de chaque doigt séparément.
