Assistive devices

Our research includes:

Physical therapy

We are developing innovative systems and muscular-skeletal models that measure and monitor human force and motion during physical therapy and activity. This knowledge will form the basis for the development of smart systems that will allow motion sensor and force resistive/assistive devices to create smart therapeutic environments for people requiring therapy. The outcome will be improved post-operation/accident rehabilitation, allowing complex physical therapy of disabled patients with minimal staff interaction, and enable independent monitoring to reduce therapist involvement.

Key applications of this work are:

• Upper limb exercising: The aim is to motivate stroke victims to use the limbs on the weaker side of their body and encourage more effective neuro-plastic retraining of the patient’s control of those limbs. 
• Force and motion measurement: A device (handheld dynamometer) has been developed that allows the simultaneous measurement of force and motion. This type of device is needed because existing methods are too subjective. 
• Home-based rehabilitation: Having the ability to conduct high-quality rehabilitation at home is a key driver for the healthcare sector. Monitoring and motivation along with cost-effective devices is key to this happening. 

• Augmented reality (AR): AR is a tool that motivates patients to generate a movement, which is then measured. Game play, which is structured to create a therapeutic exercise, provides the motivation.  The exercise can be tailored to suit the capability of the patient according to the measurements.

Independence

We are developing new knowledge on the use of body-shape conforming actuators, thin-film sensors and skeletal structural force to strengthen limb functions. One of the first applications under investigation is a power-assisted hand orthosis called the key grip device, which is being developed as part of our exoskeleton project.

This device will enable people with limited muscular strength to develop a grip that can be used for the manipulation of fine items and other activities. It incorporates active control systems, sensory interfaces and mechanical linkages.

Key applications of our exoskeleton work include:

• Medical rehabilitation: A medical exoskeleton around a patient’s limb will permit normal functioning while still allowing muscles and bones to heal, and reducing the recovery period. 
• Enhancing life: For older people, the exoskeleton technology may enable them to continue an active life in their later years.
• Manual handling for workers - A powered exoskeleton can enhance human capabilities, where total automation is not possible.
