Abstract
ABSTRACTThe modeling and experimentation of a pneumatic actuation system for the development of a soft robotic therapeutic glove is proposed in this article for the prevention of finger deformities in rheumatoid arthritis (RA) patients. The Rehabilitative Arthritis Glove (RA-Glove) is a soft robotic glove fitted with two internal inflatable actuators for lateral compression and massage of the fingers and their joints. Two mechanical models to predict the indentation and bending characteristics of the inflatable actuators based on their geometrical parameters will be presented and validated with experimental results. Experimental validation shows that the model was within a standard deviation of the experimental mean for input pressure range of 0 to 2 bars. Evaluation of the RA-Glove was also performed on six healthy human subjects. The stress distribution along the fingers of the subjects using the RA-Glove was also shown to be even and specific to the finger sizes. This article demonstrates the modeling ...

AbstractThe motion mimicry ability of patients facilitates execution of therapy moves based on visual observation of rehabilitation exercise videos, which can help speed up the recovery process. This study investigates the effects of visual feedback on the mimicking ability of human subjects in video-based rehabilitation. Inertial Measurement Unit (IMU) sensors was used, which provide a portable system to detect human motion tracking, allowing for experiments to be conducted without space restri...

Deep vein thrombosis (DVT) is a severe medical condition that affects many patients around the world, where one of the main causes is commonly associated with prolonged immobilization. Current mechanical prophylaxis systems, such as the compression stockings and intermittent pneumatic compression devices, have yet to show strong efficacy in preventing DVT. The current study aimed to develop a soft pneumatic sock prototype that uses soft extension pneumatic actuators to provide assisted ankle dor...

In this paper, we present the design, fabrication and preliminary evaluation of a soft robotic glove which can be used with functional Magnetic Resonance imaging (fMRI) during the hand continuous passive motion (CPM) in rehabilitation. The device comprises of two major components: a) soft pneumatic actuators and b) a glove. The soft pneumatic actuators, which are made of silicon elastomers, generate a bending motion and actuate the finger joints upon pressurization. As the device contains no fer...

In this paper, we present the design of a soft wearable exoskeleton that comprises of a glove embedded with pneumatic actuators of variable stiffness for hand assistive and rehabilitation application. The device is lightweight and easily wearable due to the usage of soft pneumatic actuators. A key feature of the device is the variable stiffness of the actuators at different localities that not only conform to the finger profile during actuation, but also provides customizability for different ha...

Abstract Modelling of the mechanical properties of carbon nanocomposites based on input variables like percentage weight of Carbon Nanotubes (CNT) inclusions is important for the design of medical implants and other structural scaffolds. Current constitutive models for the mechanical properties of nanocomposites may not predict well due to differences in conditions, fabrication techniques and inconsistencies in reagents properties used across industries and laboratories. Furthermore, the mechani...

Advanced computer technology can be used to design and customize a Trachea-Esophageal Puncture (TEP) voice prosthesis for speech restoration. Current voice prostheses have a standard range of sizes and shape that do not cater for all patients. This causes issues such as transprosthetic and periprosthetic leakages due to poor valve closure and misfit of the prosthesis in the patient's fistula respectively. To address these limitations, we present a Computer Aided Design (CAD) methodology that uti...

In biomedical application, conventional hard robots have been widely used for a long time. However, when they come in contact with human body especially for rehabilitation purposes, the hard and stuff nature of the robots have received a lot of drawbacks as they interfere with movement. Recently, soft robots are drawing attention due to their high customizability and compliance, especially soft actuators. In this paper, we present a soft pneumatic bending actuator and characterize the performanc...

Rheumatoid arthritis is a chronic inflammatory disease that causes pain, joint stiffness and swelling leading to impaired hand function and difficulty with daily activities. Wearing therapy gloves has been recommended by occupational therapists as one of the alternative treatment methods for rheumatoid arthritis. This study aims to review the available literature on the effects of wearing therapy gloves on patients’ hand function and symptoms as well as to discuss the attributes of gloves that m...
