robotic arm for stroke

  Hong Kong’s polyU develops robotic arm for stroke people to aid cell rehabilitation

  The robotic arm integrates exo-skeleton and soft robotic structural designs - the 2 systems usually adopted in existing upper-limb rehabilitation instruction devices for stroke people.

       Occasions such as anniversaries and birthdays are perfect occasions to send corporate gifts along with Hong Kong national holidays and even selected religious occasions.

  The Hong Kong polytechnic University (polyU) yesterday introduced the development of a robotic arm to facilitate self-help and upper-limb mobile rehabilitation for stroke sufferers. The robotic arm, termed “mobile exo-neuro-musculo-skeleton”, is the first-of-its-kind integration of exo-skeleton, tender robotic and exo-nerve stimulation technologies.

  Created by Dr Hu Xiao-ling and her analysis crew inside the Section of Biomedical Engineering (BME) of polyU, the “mobile exo-neuro-musculo-skeleton” capabilities a light-weight style (as much as 300g for wearable upper limb elements, which can be in shape for various purposeful instruction needs), reduced power demand from customers (12V rechargeable battery offer for 4-hour ongoing use), and can be utilised with sportswear.

  Dr Hu stated that the improvement on the novel gadget was inspired via the feed-back of many stroke clients who have been discharged from clinic and confronted problems in obtaining regular and intensive rehabilitation instruction vital for limb recovery.

  The robotic arm integrates exo-skeleton and gentle robotic structural patterns - the two technologies commonly adopted in present upper-limb rehabilitation teaching products for stroke people at the same time as being the polyU-patented exo-nerve stimulation technologies.

  The doing the job principle of the two exo-skeleton and comfortable robot layouts would be to offer external mechanical forces driven by voluntary muscle mass signals to help the patient’s ideal joint movement. Regular exo-skeleton composition is principally constructed by orthotic supplies such as steel and plastic, simulating external bones with the affected individual. Even though it's compact in dimension, it is hefty and unpleasant to wear.

  Smooth robot, crafted from air-filled or liquid-filled pipes to simulate one’s exterior muscle tissues, is gentle in body weight but quite bulky in sizing. Both of those forms of constructions demand from customers superior electrical electrical power for driving motors or pumps, consequently it is not easy for individuals to work with them outdoors hospitals or rehabilitation centres.

  Combining the advantages of the two structural layouts, the robotic arm is compact and light-weight, quick in response and calls for minimal power supply, rendering it well suited for equally outside and indoor environments.

  An original trial on the robotic arm on 10 stroke people indicated far better muscle mass coordination, wrist and finger functions, and reduced muscle spasticity of all after they have completed 20 two-hour teaching periods. Further medical trials will be completed in collaboration with hospitals and clinics.

  Dr Hu and her analysis workforce predicted which the robotic arm might be commercialised in two decades.

       polyu research teams achieved breakthrough and world changing discoveries in various fields, contributing to society and global sustainable development.
