Benchmarking lower limb wearable robots: towards practical and evidence-based solutions
Venue and date: Singapore, August 14, 2015 (13:30 – 17:00)
Type: Half day workshop
Keywords: Benchmarking, wearable robots, walking, performance, human-machine interaction
This workshop is supported by the EU projects H2R (www.h2rproject.eu), BALANCE (www.balance-fp7.eu) and Biomot (www.biomotproject.eu) and by the recently created network on benchmarking bipedal locomotion (www.benchmarkinglocomotion.org)
Wearable robots (WR) are entering an exciting era. An increasing number of solutions are moving out of the lab, approaching the everyday rehabilitation practice and home-based assistive applications. In this context, the quantitative assessment of the technology is crucial for its correct introduction in the market. Nevertheless, a systematic framework to evaluate the WR technology under all its facets is still lacking. In the framework of the three European projects H2R, Biomot and BALANCE, we are developing a scheme for the definition of specific benchmarks designed to lower limb WR, focused on both the global functional perspective and user-machine interaction.
This workshop wants to draw the attention of the WR community on the importance of having a common benchmarking perspective. We believe that reaching an international consensus will be extremely beneficial to boost the process of finding reliable methods to test and compare different rehabilitation systems and identifying robust metrics to measure the Technology Readiness Level (TRL) of the solutions.
This workshop comes after a series of actions directed to involve the international community in the definition of real needs and critical issues related to benchmarking of lower limb functions. These actions included: 1) a web-based survey , which received more than 160 responses from robotics and clinical researchers, 2) several sessions and workshops in the WR and humanoids communities [2-5], 3) an international network (, ) specifically addressed to this topic, to support the clustering of people and ideas.
With this workshop we would like to make a step forward, and bring together different researchers already active in the development of evidence-based evaluation methods and protocols, with the goal of identifying the critical issues in translating these approaches into consented benchmarks. The workshop is organized in 9 talks and a final round table covering different perspectives, including research, industrial, institutional and regulatory aspects.

Jan Veneman*, Rehabilitation Application Area, Tecnalia Research and Innovation
Title of the presentation: Benchmarking of balance performance in perturbed standing and walking
Abstract: This presentation focuses on benchmarking of balance performance, specifically around two subtopics. The first subtopic is related to the BALANCE project, which aims to control lower extremity exoskeletons in such a way that they support human balance-control in standing and walking. The first subtopic can be characterized as: “how to benchmark an exoskeleton, on its ability to support a human in balance performance”. Around this subtopic potential protocols for such benchmarking will be discussed. The second subtopic is related to an initiative called STARS, part of the “COST TD1006 European Network on Robotics for NeuroRehabilitation”, which aims to define metrics that allow robotic assessment of several motor skills in patients. The specific discussions around assessment of human balance performance in standing, using robotic devices, will be summarized. This second topic can be characterized as “how to assess human balance performance, using robotic devices, in the context of neurorehabilitation”.
Finally, the interconnections between both topics and the potential and difficulties for general benchmarking protocols to address wearable robotic performance as well as human performance on balance skills, will be discussed.

Robert Riener* ETH Zurich
Title of the presentation: Cybathlon: Benchmarking Assistive Devices
Abstract: The Cybathlon is an international championship for racing pilots with disabilities (i.e., parathletes) who are using advanced robotic technologies that provide assistance for daily life activities. The competitions are comprised by six different disciplines that apply the most modern actuated devices such as powered prostheses, wearable exoskeletons, powered wheelchairs, functional electrical stimulation as well as novel brain-computer interfaces. The main goal of the Cybathlon is to provide a platform for developing and benchmarking novel assistive technologies useful for the daily life of persons with motor disabilities. The well-defined admission rules, race tracks, normed obstacles and competition rules will make it possible to compare the performance of assistive devices in a life-relevant setting. The first Cybathlon will take place in a large indoor stadium in Zurich, on 8 October 2016 and will be broadcasted all over the world. Thereafter, the Cybathlon will be held periodically every 2-4 years.

Rajiv Dubey*, Ph.D. Professor and Chair, Department of Mechanical Engineering. Director, Center for Assistive, Rehabilitation & Robotics Technologies (CARRT). University of South Florida
Title of the presentation: Multi-modal assessment tools for lower limb prostheses
Abstract: The CAREN (Computer Assisted Rehabilitation Environment) is a versatile, multisensory system that includes a real-time motion capture system, a 6-DOF motion platform with a spilt belt instrumented treadmill, a projection screen, a surround sound system and an integrated software package. The CAREN system can be used to measure how individuals walk with a prosthesis and adapt to changes in the environment. By requiring lower limb amputees to face more real life scenarios while collecting objective measures using the CAREN system, issues such as prosthetic fit, alignment, and function related to patient attributes (i.e. age, etiology, amputation level) for various prosthetic configurations and components can be determined. Baseline assessments and re-creation of functional clinical tests will help examine and develop patient-centered outcomes for lower limb prosthesis users. The development of a multi-modal assessment tool, allows for a better understanding of the following: specific time points in patient treatment where prosthetic intervention is most effective; different treatment algorithms to determine the most appropriate prosthetic devices; effects of different prosthetic devices on achievement of maximal functional ability; prevention of secondary adverse consequences of prosthetic device use; and application of specific rehabilitation interventions.
