Personal profile


Dr. Christina Ma is currently an Assistant Professor in Gerontechnology (technology for older person) and a Certified Prosthetist and Orthotist (CPO, ISPO Category I) in Department of Biomedical Engineering, The Hong Kong Polytechnic University (PolyU). Before her appointment at PolyU, she served as a Lecturer, later promoted to Assistant Professor (regular appointment) in Prosthetics and Orthotics (P&O), in Department of Rehabilitation, Jönköping University, Sweden (2018-2020). She received her PhD in Assistive Technology and Rehabilitation Engineering from Faculty of Engineering, The Hong Kong Polytechnic University (2018); and BSc in Prosthetics and Orthotics from West China School of Medicine, Sichuan University (2012). She also used to work as a CPO and Clinical Instructor at China Rehabilitation Research Center (2012-2013), and a Visiting Research Scholar in Mechanical Engineering at University of Michigan (Ann Arbor) in United States (2017).


As a CPO who used to work in hospitals and rehabilitation centers, Dr. Ma is well aware of how physical disability could significantly affect the quality of life of older people and disabled persons, as well as their families. This is why Dr. Ma has a genuine interest in promoting these persons’ quality of life and developing active health strategies with research and development, and exploring the underlying mechanisms. Thanks to her multidisciplinary academic trainings in Healthcare and Engineering and her Clinical experience, Dr. Ma has been employing multiple interdisciplinary approaches (e.g. Rehabilitation, Biomechanics, Electronics, Biomedical Ultrasound Imaging, and Smart Wearable Technology) to realize her research goal. She has contributed to the evaluation and development of several smart wearable devices that could monitor the postural balance, walking pattern, and muscle contraction performance; and then provide some real-time corresponding reminders/warnings to users for necessary posture/motion adjustments. Such devices can not only act as balance/motion aids in daily life, but also facilitate community-/home-based training. Her research outcomes can benefit older people, patients with stroke, trainers/trainees of muscular fitness training, lower-limb amputees, and patients with low back pain, etc.
