PolyU develops first-of-its-kind multimodal robot empowering post-stroke ankle-foot telerehabilitation

The Hong Kong Polytechnic University (PolyU) has achieved another breakthrough in rehabilitation device development. The Mobile Ankle-foot Exoneuromusculoskeleton is the first-of-its-kind multimodal robot for ankle-foot rehabilitation specifically designed for stroke patients with hemiplegia, which helps improve the motor function of their lower limb and walking ability. Powered by Internet of Things (IoT) technology, the device enables telerehabilitation for remote management of patients’ rehabilitation progress and allows them to undertake self-help rehabilitation exercises at home. Therapists can remotely monitor the rehabilitation progress of multiple patients. In recent years, Hong Kong has seen around 50,000 new cases of stroke annually, with 85% of patients experiencing varying degrees of impaired physical mobility. Regular, repeated and intensive rehabilitation training is critical for restoring the physical mobility of stroke patients, thereby alleviating post-stroke symptoms such as disability. However, due to overwhelming demand, access to daytime outpatient rehabilitation services in local hospitals and rehabilitation clinics is challenging. Consequently, stroke patients are often unable to undergo timely and routine rehabilitation exercises. Common functional impairments among stroke patients include foot drop and inversion, which significantly disrupt their daily lives. Developed by a research team led by Dr Hu Xiaoling, Associate Professor of the Department of Biomedical Engineering of PolyU, the Mobile Ankle-foot Exoneuromusculoskeleton is an innovative multimodal wearable robot for ankle-foot rehabilitation that integrates the advantages of exoskeleton, soft pneumatic muscles, tactile sensory feedback and neuromuscular electrical stimulation technology in one system. The device can not only correct foot drop and foot inversion effectively, but also improve the gait of stroke patients. Additionally, it can help improve balance while walking and contribute to rehabilitative neuroplasticity in the long term. Stroke patients with hemiplegia generally have weakened muscle strength and discoordination at their affected lower limb, especially in the foot and ankle. The Mobile Ankle-foot Exoneuromusculoskeleton can automatically detect patients’ gait events including the standing state, heel strike, heel off and toe off. The multimodal assistance from the device can help a patient stand firm on their affected foot with mechanical support from the exoskeleton and soft pneumatic muscles, learn to balance the plantar pressure and exert propelling force when walking with the vibration tactile feedback and neuromuscular electrical stimulation, and improve foot drop with the neuromuscular electrical stimulation. The Mobile Ankle-foot Exoneuromusculoskeleton features a lightweight design weighing about 400g which, together with its sportswear features, makes it more suitable for the hemiplegic patients to wear it unilaterally on their own. This device also has the advantage of low power consumption and can be used continuously for four hours with a 9V rechargeable battery, enabling patients to practice anytime, anywhere – at home, outdoors, or indoors. Other exoskeleton lower-limb robots available on the market, which rely solely on external force to assist patients in walking, they are of very limited value in improving ankle joint and muscle coordination for stroke patients with hemiplegia. These robots are also limited to use in hospitals and rehabilitation clinics due to their high weight and power consumption. As for conventional ankle-foot orthoses, these are prone to causing muscle atrophy and interference to patients regaining voluntary motor control over the ankle of the affected leg. Dr Hu stated, “Combining the research capabilities of the Department of Biomedical Engineering, Industrial Centre, School of Fashion and Textiles and Department of Computing, the Mobile Ankle-foot Exoneuromusculoskeleton is a testament to PolyU’s exceptional strength in interdisciplinary research. This research achievement provides stroke patients a better option for lower limb rehabilitation training, incorporating the training into their daily activities. It also enables therapists to provide tele-supervision of the rehabilitation progress of multiple patients. We hope such flexible self-help training can effectively supplement traditional outpatient rehabilitation services, helping stroke patients achieve more efficient rehabilitation progress.” Dr Hu’s research team is collaborating with several local and Mainland hospitals and rehabilitation clinics to conduct clinical studies on the Mobile Ankle-foot Exoneuromusculoskeleton. Research studies have confirmed that rehabilitation training for stroke patients using the device is 40% more effective for stroke rehabilitation than applying external mechanical forces alone. Among the 12 patients participating in the clinical studies who completed a 1.5-month training programme consisting of 20 one-and-a-half-hour sessions, ankle dorsiflexion improved from an initial five degrees to 10 degrees without equipment assistance, approaching the normal level of 15 degrees. In addition, more than 90% of the patients successfully corrected their foot inversion. The research team also utilised IoT technology to record patients’ rehabilitation progress via a mobile app. This approach, incorporating functions such as real-time monitoring and progressive evaluation, as well as personalised guidance and reminders, enables patients to effectively engage in rehabilitation training even without the physical presence of a therapist, thereby improving patient engagement and treatment outcomes. The rehabilitation progresses of multiple patients can be matched to each other via the app for fostering mutual support and companionship throughout their training journey. It also enables therapists to provide remote monitoring and supervision on the progress of multiple patients, ensuring that rehabilitation proceeds smoothly. Dr Hu’s research team plans to commercialise the Mobile Ankle-foot Exoneuromusculoskeleton next year. In 2021, she co-founded the startup Thecon Technology (HK) Limited, which has been supported by the Incu-Bio Programme of Hong Kong Science and Technology Parks. Last year, the startup successfully launched a mobile exoneuromusculoskeleton for upper limb rehabilitation, the “Mobilexo Arm”, onto the market. This product has been adopted by a number of local and Mainland hospitals and rehabilitation clinics.

Propelling Biomaterial Innovations for Advanced Cell Therapy

At the heart of biomaterials research lies the pursuit of enhancing human well-being.  Translational regenerative medicine is a dynamic and rapidly advancing field that requires multi-disciplinary research approaches to develop innovative clinical solutions, therapies, and devices to improve human health and well-being. Dr Xin ZHAO, Limin Endowed Young Scholar in Biomaterials and Tissue Engineering, Associate Professor in Department of Applied Biology and Chemical Technology of The Hong Kong Polytechnic University (PolyU), is at the forefront of this field.  Dr ZHAO's research interests involve the integration of multidisciplinary approaches, combining various fields such as material science, cell biology, engineering and medicine. The focus of her studies is on modulating cell microenvironments, manipulating cell behaviours and advancing tissue-engineered organ development. To synthesise patient-oriented biomaterials with unique structures and properties, her research team actively investigates how cells sense, interact and develop with biomaterials to regenerate damaged or diseased tissues.  Dr ZHAO said, “I begin by conducting a comprehensive study of the needs and developing a fundamental understanding of the clinical problem. I then design biomaterials with tailored features and structures to provide effective solutions.”  Specifically, photocrosslinkable polymers play a pivotal role in the research. They have garnered significant attention in the field of regenerative medicine due to their mild polymerization conditions, highly tunable physical properties, excellent biocompatibility and precise spatiotemporal control. These polymers offer immense potential for replacing or regenerating diseased or damaged tissues, such as skin and bone. In her research journey, Dr Zhao endeavours to develop and advance the revolutionary application potential of these materials for tissue engineering.   Uncovering practical uniqueness  Dr ZHAO’s discovery of the Photocrosslinkable Gelatin (GelMA) hydrogel offers a breakthrough solution in epidermal tissue engineering, which exceeds the conventional limitations of collagen- or gelatin-based hydrogels. Due to its tunable mechanical, degradation, and biological properties, GelMA hydrogel emerges as a promising option for various applications, such as epidermal substitutes, wound dressings, or substrates, to construct various in vitro skin models.  The research “Photocrosslinkable Gelatin Hydrogel for Epidermal Tissue Engineering” was published in Advanced Healthcare Materials, and has garnered widespread citations.1  The ability of cells to attach, spread and grow on hydrogels is fundamentally important to tissue development. Photocrosslinkable GelMA hydrogel with tunable mechanical and degradation features ideally makes it suited for skin-tissue engineering scaffolds. By varying the concentration of GelMA prepolymer solution, the physical and biological properties of the resulting hydrogels could be adequately controlled to meet the requirement for epidermis formation.  Hydrogels of higher concentrations display improved material mechanical and degradation properties for cell adhesion and keratinocyte monolayer formation. Also, GelMA hydrogels support the formation of a stratified epidermis with certain barrier functions such as electrical resistance and prevention of water loss.    Persistent pursuit of novel approaches Dr ZHAO and her research team have showcased the exceptional processability of photocrosslinkable polymers, rendering them inherently compatible with a diverse range of biomanufacturing technologies. Their groundbreaking work has unveiled a multitude of new possibilities in this field.  Stem cell transplantation has emerged as a promising treatment for various injuries ranging from bone fractures to bone cancers and for other disorders. Very often, bone marrow-derived mesenchymal stem cells (BMSCs) are used for bone regeneration due to their osteogenic differentiation potential. In this research area, Dr ZHAO presents a strategy of microfluidics-assisted technology encapsulating BMSCs and growth factors in photocrosslinkable GelMA microspheres to ultimately generate injectable osteogenic tissues constructs.  The findings were published in Advanced Functional Materials, titled “Injectable Stem Cell-Laden Photocrosslinkable Microspheres Fabricated Using Microfluidics for Rapid Generation of Osteogenic Tissue Constructs”. The research demonstrated that the GelMA microspheres can sustain stem cell viability and proliferation, support cell spreading inside the microspheres, and facilitate migration from the interior to the surface.2 In vitro and in vivo studies showed that BMSCs encapsulated GelMA microspheres exhibit enhanced osteogenesis. This approach holds promise for facilitating bone regeneration with minimum invasiveness and can potentially be combined with other matrices for broader applications.  Putting patients at the centre “Scientific research is a highly dynamic field that demands continuous innovation. It allows us to delve into fascinating new phenomena and discover unexplored realms that undoubtedly broaden our horizons,” said Dr ZHAO.  Large-scale bone defects caused by injuries, diseases, or trauma impose significant challenges in orthopaedic surgery due to the limited capacity of damaged bone tissues for self-repair and complete remodelling. Dr ZHAO has persistently investigated a new approach to advance therapeutic development in this area. In particular, for 3D printing, it shows great potential in the rapid and accurate fabrication of bone tissue engineering scaffolds to the patients’ needs.  Dr ZHAO’s team envisions the novel photocrosslinkable nanocomposite ink as an ideal candidate for 3D printing bone grafts. The research “Photocrosslinkable nanocomposite ink for printing strong, biodegradable and bioactive bone graft” was published in Biomaterials and has received significant attention.3 Compared with commonly used polymer or composite inks, the proposed material holds great promise in the 3D printing of bone grafts tailored to meet the specific needs of patients. This is attributed to its suitable rheological characteristics, rapid photocrosslinking solidification, adequate mechanical strength and toughness, tunable degradation rate and excellent bioactivity. Both in vitro and in vivo studies demonstrated excellent biocompatibility and osteogenic potential of the printed nanocomposite scaffolds.  Dr ZHAO said, “I believe that accumulating numerous citations is a cherished goal for every researcher. By making a high impact with research, it inspires further exploration and expands the functionality and applications of the developed materials. These collective efforts foster the development of superior materials and innovative solutions to clinical challenges.” Research Interests: Biomaterials, Drug Delivery, Tissue Engineering, Cell Micro-environment, Microfluidics Highly Cited Researcher: 2022 (Clarivate Analytics) Selected Highly Cited Publications: X.

PolyU and Rohto join forces to establish the Centre of Research Excellence for Eye Care

The Hong Kong Polytechnic University (PolyU) partnered with Rohto, an eye care brand under Mentholatum, to establish the PolyU-Rohto Centre of Research Excellence for Eye Care (“the Centre”). The Centre’s inauguration took place at the “Leading Research in Eye Fatigue, Empowering the Joy of Seeing” launch ceremony held in Hong Kong. During the event, PolyU and Rohto also jointly released the “Promoting Healthy Vision and Prioritizing Standardised Diagnosis of Eye Fatigue” advocacy paper, which aims to enhance eye health within the broader community. Honourable guests witnessing this significant event included Prof. Jin-Guang TENG, President of PolyU, Prof. Christopher CHAO, Vice President (Research and Innovation), Prof. ZuanKai WANG, Associate Vice President (Research and Innovation), Prof. David SHUM, Dean of Faculty of Health and Social Sciences, Prof. Mingguang HE, Director of the PolyU-Rohto Centre of Research Excellence for Eye Care and Chair Professor of Experimental Ophthalmology School of Optometry, Mr Michael SIN, President of Mentholatum Asia Pacific, and Mr Wesley CHAN, General Manager of Sales and Marketing, Mentholatum (China) Pharmaceutical Co., Ltd. Establishment of The PolyU-Rohto Centre of Research Excellence for Eye Care marks a breakthrough for the optometry industry At the launch ceremony, Prof. Teng, said, "The University's School of Optometry is one of the world's leading institutions in optometry and vision science, and PolyU is the only university in Hong Kong offering optometry education. We have established several research centres related to ophthalmology, including the Centre for Eye and Vision Research launched with the University of Waterloo in Canada and supported by the HKSAR Government, as well as the Centre for Vision Science Research under the PolyU Academy for Interdisciplinary Research. The partnership with Rohto represents a powerful alliance in eye care." Moving forward, the Centre will gather teams of ophthalmic experts to conduct research and testing in multiple locations and establish collaborative networks with various regions to develop eye health and care technologies, aiming to provide comprehensive medical and care solutions for eye fatigue. Early attention is crucial in the face of rising eye fatigue cases Prof. Mingguang He, Director of the PolyU-Rohto Centre of Research Excellence for Eye Care and renowned scholar in the international optometry field, corroborated these findings at the launch ceremony, stating “Due to society’s digital transformation and fast-paced lifestyles, eye-fatigue problems are increasingly prevalent. This problem can significantly impact both quality of life and work efficiency, but the majority of people tend to overlook its significance.” Prof. Mingguang He also noted that eye fatigue is caused by prolonged eye usage, leading to tiredness and discomfort. It already affects approximately 20-30% of children and adolescents and 50-80% of adults, including university students and office workers who use computers extensively. However, the establishment of an innovative and standardised treatment system for eye fatigue is still a work in progress. Currently, the traditional diagnosis of eye fatigue relies heavily on subjective questionnaires, while treatment methods vary, lacking a unified objective diagnostic standard and evaluation. As a result, eye fatigue is often overlooked by patients and clinical practitioners, leading to a relatively limited understanding of this condition in terms of both public awareness and academic research. It is crucial to prioritise high-quality research into and resolution of eye fatigue issues. Rohto partners with PolyU to introduce Eye Fatigue advocacy: Enhancing public eye health in four key areas The low level of public awareness of eye fatigue and the existing diagnosis system being ill-prepared to effectively tackle this issue are of growing concern. Mr Michael Sin, President of Mentholatum Asia Pacific, said, "Mentholatum holds a strong commitment to scientific research, grounding its practices in scientific principles and relying on experimental evidence. It prides itself on introducing products of the highest quality. The Rohto brand is recognised as the world's leading eye-care brand. Over the years, Mentholatum has been dedicated to promoting eye health, particularly through the development and introduction of a range of eye drops targeting eye fatigue. We are honoured to collaborate with The Hong Kong Polytechnic University in establishing the PolyU-Rohto Centre of Research Excellence for Eye Care. We share a common vision in promoting research into eye fatigue, recruiting talented individuals, and focusing on the study of eye-fatigue technology to aid in treatment and alleviate the impact of eye fatigue, allowing us to appreciate the world with our eyes to the fullest.” On this occasion, Rohto and PolyU also jointly announced the launch of the "Promoting Healthy Vision and Prioritizing Standardised Diagnosis of Eye Fatigue" advocacy paper." This advocacy, centred around the "Know-Diagnose-Explore-Engage" framework, aims to enhance public awareness of eye fatigue. Its objectives are to establish and promote globally unified diagnostic standards and develop a multi-level diagnosis system. It also seeks to explore new prevention methods and treatment approaches. Through collaboration with various sectors, the Centre is dedicated to creating a healthy environment for eye health, cultivating healthy eye habits, and mitigating the impact of visual fatigue on public eye health, thereby improving individuals' quality of life.
