Over the last ten years Dr. Freeman has developed new healthcare technologies combining robotics and electrical stimulation to enable people with upper limb impairments to perform functional tasks. Over this time he has worked closely with clinicians (including former IFESS president Prof Jane Burridge), patients and carers. These include five clinical trials using technology he has developed, as well as numerous smaller studies and user-led design sessions. His focus has been to understand and define clinical problems within an engineering perspective and translate this into usable solutions.
Dr. Freeman’s background in adaptive and learning control of robotic structures has enabled him to rigorously tackle the challenge of designing systems that provide high performance in the face of significant model uncertainty/variability, restrictive clinical conditions, and complex dynamics/tasks. These problems have led to a productive interaction in his research between theory and practice (the latter generally providing new problems that need an algorithmic or theoretical solution). This is reflected in my publications which include 70 peer-reviewed journal papers and 130 peer-reviewed conference papers covering the spectrum from control application,
control theory, rehabilitation engineering, biomechanics, clinical studies and user perspectives. The research he has led in control of ES has elicited two best conference paper awards (ICORR ’09, UKACC ’12), and two best journal paper awards (most recently `2013 IEEE Control Systems Society Outstanding Paper Award’ based on `impact on the field of systems and control’). For example, his work using iterative learning control and adaptive control for stroke rehabilitation has met with an enthusiastic response from the research community, with invited workshops at IEEE Bio Rob Conference 2012, 18th IFESS Conference 2013, World Congress in Neuro Rehabilitation 2014, as well as a plenary at IEEE International Workshop on n D Systems 2013. Citations for my research using both ES and advanced control in the last 5 years exceed 500.
In a wider content, the last 10 years has seen a steady increase in research papers, funding calls, and postgraduate courses related to assistive technologies. An example of the latter is an EU-funded MSc in ‘Advanced Rehabilitation Technologies’ involving 10 EU partners that he is currently helping to develop.
His work in control design for systems combining ES and mechanical support is motivated by the lack of model-based controllers that reach clinical or commercial application and it has elicits an international response, from TU Berlin, ETH Zurich, U. Washington and U. California who have since applied iterative learning control-based FES to the lower limb.
