The Technology to Enhance Patient Motivation in Virtual Reality Rehabilitation: A Review

Virtual reality (VR) technology has experienced a steady rise and has been widely applied in the field of rehabilitation. The integration of VR technology in rehabilitation has shown promising results in enhancing their motivation for treatment, thereby enabling patients to actively engage in rehab training. Despite the advancement, there is a dearth of comprehensive summary and analysis on the use of VR technology to enhance patient motivation in rehabilitation. Thus, this narrative review aims to evaluate the potential of VR technology in enhancing patient motivation during motor rehabilitation training. This review commences with an explanation of how enhancing motivation through the VR rehabilitation system could improve the efficiency and effectiveness of rehabilitation training. Then, the technology was analyzed to improve patient motivation in the present VR rehabilitation system in detail. Furthermore, these technologies are classified and summarized to provide a comprehensive overview of the state-of-the-art approaches for enhancing patient motivation in VR rehabilitation. Findings showed VR rehabilitation training utilizes game-like exercises to enhance the engagement and enjoyment of rehabilitation training. By immersing patients in a simulated environment with multisensory feedback, VR systems offer a unique approach to rehabilitation that can lead to improved patient motivation. Both ultimately lead to improved patient outcomes, which is not typically achievable with traditional rehabilitation methods. The review concludes that VR rehabilitation presents an opportunity to improve patient motivation and adherence to long-term rehabilitation training. However, to further enhance patient self-efficacy, VR rehabilitation should integrate psychology and incorporate methods. Moreover, it is necessary to build a game design theory for rehabilitation games, and the latest VR feedback technology should also be introduced.

INFLUENCES OF LOWER LIMB STRENGTHENING ON MARTIAL ARTS TEACHING

ABSTRACT Introduction: One of the focuses of research on martial arts education is how to improve the assistance of martial arts teaching through strength training directed to sports movements. Scientific contributions about the influence of these strengths can underpin athletes’ training. Objective: Study the influences of lower limb strength training on the abilities of martial arts students. Methods: 20 students from a college martial arts class were randomly selected as volunteers for the experiment. They were divided into the experimental group, which performed systematic lower limb strength training according to a specific protocol, and the control group, which performed traditional exercise, and basic physical training in the physical education institute. The experiment lasted eight weeks. The relevant data were analyzed statistically. Results: Left unipodal balance ability in the experimental group increased from 43.646s before training to 56.110s, with an increased rate of 22.213%; right unipodal balance ability increased from 43.845s before training to 57.126s, with an increased rate of 23.249%. Conclusion: It is recommended to integrate targeted training methods, such as lower limb muscle training, into the martial arts teaching process to improve the physical quality of martial arts athletes due to the benefits observed in their teaching process.

Electrically Driven Lower Limb Exoskeleton Rehabilitation Robot Based on Anthropomorphic Design

To help people with impairment of lower extremity movement regain the ability to stand and walk, and to enhance limb function, this study proposes an anthropomorphic design of an electrically driven, lower-limb exoskeleton rehabilitation robot. The angular range of the robot’s motion was determined according to the characteristics of the targeted lower-limb joints; the robot was given an active–passive anthropomorphic design with 12 degrees of freedom. The multi-degree-of-freedom hip exoskeleton, bionic artificial knee exoskeleton and passive rigid-flexible coupling ankle exoskeleton can assist patients in rehabilitation exercises with better wear comfort and exercise flexibility. A kinetic model of the seven-rod lower-limb exoskeleton rehabilitation robot was built, and data analysis of the dynamically captured motion trajectory was conducted. These provided a theoretical basis for gait planning and the control system of the lower-limb exoskeleton rehabilitation robot. The results show that the lower-limb exoskeleton rehabilitation robot system possesses sound wearing comfort and movement flexibility, and the degree of freedom of movement of the exoskeleton robot matches well with that of human movement. The robot can thus provide effective assistance to patients’ standing and walking rehabilitation training.
