    Abstract:

    Objective:To study the sensory system characteristics of posture control in stroke patients, and to analyze the contribution rate and utilization rate of each receptor to the postural control ability of stroke patients. Methods:From January 2019 to July 2022, 30 elderly stroke patients (patient group) and 30 healthy elderly patients (control group) in our hospital were tested for sensory integration by computer dynamic posture tracing system, and the sensory integration tests under 6 conditions were recorded. Balance score, balance comprehensive score, and calculate the contribution rate and overall utilization rate of vision, proprioception, and vestibular sense under different standing conditions. Results:The balance score of the patient group was lower than that of the control group under the conditions of closed eyes/stable support surface, visual disturbance/stable support surface, closed eyes/unstable support surface, and visual disturbance/unstable support surface (Z=-3.248, p=0.001)、(Z=-2.829, p =0.005)、(Z=-4.283, p =0.000)、(Z=-4.074, p =0.000), the balance comprehensive score was significantly lower than that of the control group (Z=-4.133, p=0.000). In the Eyes-open/stable-support and eyes-closed/stable-support tests, the proportion of proprioception in the patient group was 16.351% and 34.942%, respectively, and the proportion of proprioception in the control group was 14.307% and 18.390%, respectively. The effect of the group was greater than that of the control group. Similarly, the effect of vision on the patient group was greater than that in the control group. The lowest contribution rate of vestibular sense under different standing conditions was 64.648%, indicating that the main factor to maintain the balance of human body is vestibular sense. The utilization rates of proprioception, vision and vestibular sense in the patient group were decreased sequentially, which were 95.092%, 72.382%, and 32.879%, respectively. The utilization rate of proprioception and vestibular sense was significantly lower than that of the control group(Z=-1.984,p=0.047)、(Z=-4.283,p=0.000). Conclusions:The decline in the contribution and utilization of sensory system in stroke patients is one of the important factors for stroke patients with postural control disorders. Posture control contributed the most to vestibular sense, followed by proprioception and vision. The biggest utilization rate of posture control is proprioception, followed by vision and vestibular sense. One of the reasons that affect the decline of posture control ability of stroke patients is the decline of proprioception and visual sensory information input of stroke patients, as well as the partial decrease of proprioception and vestibular sense participating in motor output. It is suggested that stroke patients should pay attention to the training of proprioception and vestibular sense to improve their posture control ability.
