Combining 3D printing technology to design a hand dynamic orthosis for stroke patients

2020-08-11

Hand rehabilitation of stroke is always a big problem for patients. Because of the lack of appropriate training equipment, the rehabilitation of hands cannot be done correctly and efficiently. A large numbers of hand exercises cannot be performed and learned properly, so that the recovery of hand functions cannot meet the requirements. Not only will it affect the functions of daily life, most patients will finally choose to give up. The invention of this orthosis combines 3D printing technology and traditional splinting technology to custom-made the individualized training equipment for stroke patients. It can be used to adjust the appropriate tension in response to the interference of various abnormal muscle tone. It also helps the affected hand with difficulty of grasping and releasing to perform these exercises many times in a short- term period. Then the large amount of repeated exercises will help promote the possibility of hand function recovery.

 

Product features

 

  1. Suitable for patients who can hold their hands but are not easy to open after stroke.
  2. Combined with 3D printed parts and hardware materials, it is mounted on the custom-made forearm base made by splinting materials, which has excellent conformability and stability.
  3. With the elasticity of the external elastic mechanism and the special finger cuff design, the patient's grasping action can be as close as possible to the normal action mode to achieve correct action learning and training.
  4. It can adjust the most appropriate resistance of each finger according to the muscle tone change at any situation.
  5. It allows the patient to effectively and repeatedly practice finger grasping & releasing exercises, which greatly increases the number of exercises compared to traditional treatment.
  6. This orthosis is suitable for in the home environment, repeat practice at any time by yourself, and use simple grasping activities in daily life.
  7. Patent registered (No.M54431)
