“…Using virtual reality to contextualize a test environment to assess the risk of falls [13] requires an interest in motor changes induced by VR. In a previous study [14], we used the Timed Up and Go task [15] to compare the time and number of steps required to complete the task in real life and in a virtual environment simulating a real-life situation.…”

Background/Aims: Falling among the elderly is a major public health issue, especially with the advancing age of the baby boomers. The fall risk assessment tests for many lack a context that would bring them closer to everyday life. Thus, immersive virtual reality, which makes it possible to simulate everyday situations, could make it possible to strengthen the quality of the assessment of the risk of falls. However, it is necessary to understand how the use of a virtual reality device influences the motor control of elderly participants. If vestibular physiotherapists use VR to virtualize their tools, what impact would a visual simulation of movement have on motor control in a locomotor task, if this simulation were plausible? Methods: Sixty-two elders (70.8 ± 6.7 years old) completed a Timed Up and Go task under 3 conditions: real, virtual reality, and virtual reality with visual and sound movement information. The virtual reality task takes place in a train either stationary at a station or in uniform linear motion. The time and number of steps were recorded using video, and comparisons between conditions were made using Friedman’s test. Results: The results show a significant increase in the time and number of steps in “virtual reality” condition compared to the “real” condition. They do not show significant differences between the 2 virtual conditions. Conclusion: The use of a running virtual train to provide plausible movement is particularly distinguished from vestibular physiotherapy applications with first a fixed visual support partially obscuring the optical flow. This visual aid coupled with the attention dedicated to the task inhibits the effect of the moving environment on locomotion. However, the visual optical flow will potentially have an effect in people with fear of falling. Virtual reality shows great potential for the simulation of realistic environments for the assessment of the risk of falls and opens up avenues for the development of tests.

“…In recent years, some scholars have studied the strategy of taking multiple steps to restore balance when the elderly are about to fall under certain disturbances, indicating that the movement training of the elderly in the front, back, left and right directions can help the elderly master balance and prevent body posture control. The various dangers brought by the decline [4][5]. Based on this, some studies have proposed to improve this problem through exercises that exercise the front, back, left, and right directions of the limbs, such as multi-directional movement training, whole-body vibration training, uniform jogging, tennis exercises, and Tai Chi.…”

In today's society, the rate of population aging is getting faster and faster, and the health of the elderly has attracted much attention. It has been found that many elderly physical diseases are caused by the long-term bad habits and lack of exercise in the elderly. More and more studies have shown that proper exercise can prevent and reduce the occurrence of these diseases. With the development of smart sensor technology and the application of artificial intelligence technology, smart sensors have been used to monitor various body information data of the elderly, and play an important role in studying the influence of various sports exercises on the ability of the elderly to control their body posture. This article uses the intelligent sensor system to study the influence of tennis practice on the control ability of the elderly's body posture. This article first analyzes the knowledge of sports mechanics in tennis practice through literature research, formulates correct and comfortable tennis practice methods suitable for the elderly, and uses smart sensors to track and monitor the body posture data of the elderly. Then this paper uses a particle filter-based sensor target tracking model to monitor the elderly's fall, and uses a fourth-order Butterworth filter to evaluate the elderly's body posture control ability. Then this paper uses BP neural network to recognize and analyze the body posture of the elderly and predict the posture control ability. Finally, a comparative analysis of the effect of tennis exercises on the body control ability of the elderly is carried out through the control experiment of the elderly body posture test. Experiments show that tennis exercises can significantly improve the body control ability of the elderly, especially the lateral posture control.
