Hong Kong’s polyU develops robotic arm for stroke patients to aid cell rehabilitation
The robotic arm integrates exo-skeleton and comfortable robot structural layouts - the 2 systems normally adopted in current upper-limb rehabilitation education products for stroke individuals.

The Hong Kong polytechnic University (polyU) yesterday announced the event of a robotic arm to facilitate self-help and upper-limb cell rehabilitation for stroke individuals. The robotic arm, called “mobile exo-neuro-musculo-skeleton”, could be the first-of-its-kind integration of exo-skeleton, comfortable robot and exo-nerve stimulation systems.
Made by Dr Hu Xiao-ling and her exploration staff during the Division of Biomedical Engineering (BME) of polyU, the “mobile exo-neuro-musculo-skeleton” functions a light-weight design and style (as much as 300g for wearable higher limb components, that happen to be fit for various practical instruction desires), minimal ability demand from customers (12V rechargeable battery offer for 4-hour continual use), and might be utilised with sportswear.
Occasions such as anniversaries and birthdays are perfect occasions to send corporate gifts along with Hong Kong national holidays and even selected religious occasions.
Dr Hu mentioned that the improvement in the novel unit was influenced because of the opinions of numerous stroke individuals who were being discharged from healthcare facility and confronted challenges in possessing frequent and intensive rehabilitation teaching essential for limb restoration.
The robotic arm integrates exo-skeleton and gentle robot structural styles - the 2 systems normally adopted in current upper-limb rehabilitation coaching products for stroke individuals as well as the polyU-patented exo-nerve stimulation technologies.
The working theory of both exo-skeleton and gentle robot designs is usually to present external mechanical forces pushed by voluntary muscle mass alerts to assist the patient’s sought after joint movement. Conventional exo-skeleton structure is especially produced by orthotic resources these as steel and plastic, simulating external bones of your client. Whilst it truly is compact in dimension, it really is major and unpleasant to put on.
Tender robotic, crafted from air-filled or liquid-filled pipes to simulate one’s external muscle tissues, is gentle in pounds but incredibly cumbersome in sizing. Both equally kinds of constructions desire higher electrical energy for driving motors or pumps, therefore it's not easy for sufferers to utilize them outdoors hospitals or rehabilitation centres.
Combining the advantages of both equally structural patterns, the robotic arm is compact and lightweight, quick in response and calls for minimum electrical power offer, rendering it ideal for both outside and indoor environments.
An first demo with the robotic arm on 10 stroke people indicated better muscle coordination, wrist and finger capabilities, and decrease muscle mass spasticity of all once they have done twenty two-hour coaching sessions. Further clinical trials might be performed in collaboration with hospitals and clinics.
Dr Hu and her analysis group anticipated which the robotic arm may be commercialised in two years.
polyu research teams achieved breakthrough and world changing discoveries in various fields, contributing to society and global sustainable development.相關文章：
