Rehabilitation Meets Internet: A Paradigm Shift in Therapy Delivery
Before delving into rehabilitation medicine, let us first examine a set of data:
According to PwC's research and statistics,In developed countries, the average ratio of rehabilitation therapists to the general population is 5 per 100,000 people, whereas in China, the ratio is only 0.4 per 100,000—a 12.5-fold difference.; According to statistics from the National Health and Family Planning Commission, data on rehabilitation hospitals in China in 2012 showed that there were only 322 rehabilitation hospitals nationwide, with 206 located in urban areas and 116 in rural areas. This means that more than half of the over 600 cities across China still do not have specialized rehabilitation hospitals.
Furthermore, according to a report by the Data Research Center of Guan Yan Tian Xia, 154.9 million people in China had rehabilitation needs in 2011, including nearly 100 million elderly individuals. As the aging process accelerates, this demand is becoming increasingly pronounced.
In China, rehabilitation medicine is primarily composed of rehabilitation departments in public hospitals, public rehabilitation treatment centers, and socially operated rehabilitation enterprises.These sessions typically involve one-on-one training between a physical therapist and a patient, which presents several limitations: (1) insufficient available resources, including both professional rehabilitation physicians and rehabilitation equipment; (2) monotonous, tedious, and highly repetitive training processes; and (3) difficulty in achieving quantitative functional assessment, as the intensity of physical activity fluctuates continuously during training.In short, the current rehabilitation therapy system struggles to meet the demand for diversified, convenient, and customized services.
How to Solve It? Small-Scale Initiatives Are Always More Effective at Breaking Through Limitations Than the Broader Environment.
According to VCBeat’s analysis, there are currently three major advanced approaches in rehabilitation medicine:(1) Rehabilitation robots; (2) Software: system software (virtual reality) and applications; (3) Wearable devices.
Diseases targeted mainly include:
Neurological Disorders and Disabilities
Musculoskeletal Diseases and Disabilities
Cardiovascular and Respiratory Diseases
Other (burns, cancer, chronic pain, diabetes, dental diseases)
Let’s begin by importing from the product attributes.
1) Rehabilitation Robots
In countries such as those in Europe, the United States, and Japan, the market share of medical rehabilitation robots has been increasing year by year. In Japan alone, the robot market rose to approximately USD 1.05 million in 2010.Its growth rate ranks first among all application areas of robots.Rehabilitation robots are generally categorized into rehabilitation training robots and assistive rehabilitation robots. Rehabilitation training robots primarily help patients perform various active and passive rehabilitation exercises, such as gait training, arm movement training, spinal movement training, and neck movement training. Assistive rehabilitation robots are mainly used to help patients with limb movement difficulties perform various actions, such as smart prosthetics, guide robots, and service robots.
▼ Walking Robot
Assistant Professor Yu Haoyong of the National University of Singapore led a team in developing a walking robot equipped with a body harness sensor system to monitor the user’s current gait. To adjust the gait to an appropriate rhythm, the robot delivers electrical stimulation to specific muscle groups at key points during the walking cycle. Physiotherapists can also configure “resistance levels” on the robot to facilitate gait training for patients.
Furthermore, during assisted walking, the robot collects the user’s gait and muscle data, enabling physical therapists to continuously refine rehabilitation plans in subsequent treatment.
▼MIT-MANUS Robot
A research team from the Massachusetts Institute of Technology and Spaulding Rehabilitation Hospital has developed a robot known as MIT-Manus, a 30-inch-tall robotic arm that can be connected to a computer screen. By securing the stroke patient’s arm to the robotic arm, the device can guide movements of the patient’s shoulder and elbow, which are displayed as cursor movements on the computer screen. The robot can exercise the stroke patient’s arm in a manner similar to that of a physical therapist, thereby helping to restore motor function in the shoulder and elbow impaired by stroke-induced paralysis.
▼ Germany’s Care-O-Bot II
A Mobile Home Care System to Assist People with Disabilities and the Elderly in Living Independently. It can arrange tables and chairs, serve beverages, and control air conditioning and alarm systems; it can support users in rising from bed or chairs and provide intelligent walking assistance; it also manages media such as video calls and television, facilitates communication with medical and public service institutions, monitors hazard signals, and initiates emergency calls for help.
2) Software System
There are two main types of software applications used in rehabilitation: virtual reality and mobile applications.
▼ Applications of Virtual Reality in Rehabilitation Medicine
VR rehabilitation systems can overcome the limitations of traditional training methods by providing tailored virtual training platforms for patients with various types of functional impairments. Through positive motivational feedback delivered via music, visuals, text, and voice prompts, these systems enable patients to engage in rehabilitation exercises through gamified or entertaining tasks, thereby enhancing their motivation. Furthermore, the system meticulously records patient training data, allowing rehabilitation physicians to remotely monitor progress, adjust training plans and intensity in real time as needed, and recommend appropriate rehabilitation treatment protocols. This approach enables a single physician to simultaneously guide multiple patients.
The applications of virtual reality in rehabilitation medicine are mainly manifested in three aspects: motor rehabilitation, cognitive rehabilitation, and telerehabilitation.
1. Applications of VR in Sports Rehabilitation
Movement disorders refer to a variety of conditions characterized by abnormal movements, including symptoms such as akinesia, chorea, and tics. Currently, in the field of movement disorder rehabilitation, the most significant application of VR technology is rehabilitative training for patients’ impaired motor functions, encompassing balance and coordination training, gait and walking training, and upper and lower limb rehabilitation training.
● Virtual Rehabilitation System
Holden et al. developed a virtual rehabilitation system that enables patients to consciously acquire various limb movements by imitating the actions of a virtual instructor. The virtual software within the system includes a basic three-dimensional graphics module, which can generate different therapeutic scenarios tailored to the patient’s specific condition. These scenarios typically involve simple tasks, such as hammering nails.
Currently, there are approximately 20 virtual training scenarios, each encompassing multiple difficulty levels. During training, an electromagnetic motion tracking device simultaneously records the movements of both the virtual instructor and the patient. By monitoring and comparing the trajectory differences in their limb movements, extensive feedback can be provided to the patient through verbal instructions or cue-based matching.
2. Application of VR in Cognitive Rehabilitation
According to encyclopedic sources, cognition refers to the process by which the human brain receives external information, processes and transforms it into internal psychological activities, thereby acquiring or applying knowledge. This process encompasses memory, language, executive function, calculation, and comprehension and judgment. The integration of virtual reality (VR) with cognitive rehabilitation offers distinct advantages over traditional methods by providing patients with safe, controlled stimuli within a virtual environment for therapeutic purposes, while simultaneously monitoring multiple critical indicators.
VERA
Visual Technology Applications, Inc., based in Philadelphia, USA, has developed VERA, a software-based screening system that enables accurate administration of standard visual examinations on computers while automatically generating precise result reports and forms. VERA employs automated tracking methods to facilitate optimized vision therapy protocols and enhance communication among teachers, patients, ophthalmologists, and school administrators.
3. Applications of VR in Remote Rehabilitation
VR combined with network communication technology can deliver top-tier medical resources to less developed regions.
Exoskeleton-based Tele-rehabilitation System
A three-degree-of-freedom exoskeleton-based telerehabilitation system was developed. During rehabilitation training, the exoskeleton system drives the patient’s upper limb to perform shoulder flexion/extension, abduction/adduction, and elbow flexion/extension movements. Virtual reality technology was employed to create a virtual human and a virtual environment. The virtual human, situated within the virtual environment, moves in synchrony with the patient and enables navigation through the scene, thereby enhancing the engagement of rehabilitation training and yielding improved therapeutic outcomes.
▼ Applications
Unlike the aforementioned attributes, the primary characteristic of this product category is its mobility; it leverages the convenience of mobile platforms to connect patients with rehabilitation therapists, hospitals, and enterprises providing rehabilitation services.
Rehabilitation for Lower Limbs
A clinical app developed by 3D4Medical.com, LLC, designed to help physical therapists and healthcare professionals visually and effectively communicate injuries and exercise rehabilitation to their patients. This app also serves as a patient education tool for individuals with injuries. Furthermore, it is an excellent visual aid for exercise therapy. The application includes 165 types of injuries, providing anatomical structures and descriptions for each, along with clinically applicable training methods for reference.
idoo rehab
It aims to guide users on how to exercise and assess whether their training methods are correct (primarily by analyzing data from the phone’s motion sensors). idoo rehab is primarily designed to aid post-injury recovery and provide support to those who need it most. Additionally, users can consult with doctors and physical therapists anytime, anywhere.
In China, a rough count by VCBeat across major app marketplaces reveals nearly 100 rehabilitation apps currently available. The majority offer in-home rehabilitation services, while others focus on community-based or hospital-based rehabilitation. Furthermore, many domestic platforms provide free online voice-guided rehabilitation instructions, self-diagnosis and self-treatment tools, and medication reminders, leveraging an Online-to-Offline (O+O) model to build their service networks. In contrast, foreign markets, benefiting from the maturity of advanced technologies, tend to favor more direct and in-depth virtual video guidance delivered online. Meanwhile, China’s “O+O” model offers broader service coverage and greater choice.
▼Wearable Devices
Wearable applications primarily enhance muscle strength through portable therapeutic methods, thereby improving rehabilitation outcomes and promoting patients' social participation.
MusicGlove
U.S. startup Flint Rehabilitation Devices has launched MusicGlove, a musical glove designed to assist stroke patients with finger rehabilitation therapy.
MusicGlove resembles an electronic glove, with sensors at each fingertip to capture finger movements. It offers two dedicated compatible devices for home and clinical settings: tablets and desktop computers. After connecting the glove to a tablet or computer and completing simple setup procedures, patients can wear the glove and perform rehabilitative finger exercises by following a series of therapeutic music games similar to “Rhythm Master” displayed on the screen.
During patient use, MusicGlove precisely records data on fine finger movements, enabling therapists to monitor progress in real time and adjust hand function rehabilitation goals accordingly, thereby significantly enhancing treatment outcomes.
