Dizziness is one of the most common symptoms in the general population. Patients with dizziness experience balance problems and anxiety, which can lead to decreased physical activity levels and participation in their daily activities. Moreover, recovery of vestibular function from vestibular injury requires physical activity. Although there are reports that decreased physical activity is associated with handicap, anxiety, postural instability and reduced recovery of vestibular function in patients with chronic dizziness, these data were collected by self-report questionnaires. Therefore, the objective data of physical activity and the relationships between physical activity, handicap, anxiety and postural stability in patients with chronic dizziness are not clear. The purpose of this research was to objectively measure the physical activity of patients with chronic dizziness in daily living as well as handicap, anxiety and postural stability compared to healthy adults. Additionally, we aimed to investigate the relationships between physical activity, handicap, anxiety and postural stability in patients with chronic dizziness.
Twenty-eight patients with chronic dizziness of more than 3 months caused by unilateral vestibular hypofunction (patient group) and twenty-eight age-matched community dwelling healthy adults (healthy group) participated in this study. The amount of physical activity including time of sedentary behavior, light physical activity, moderate to vigorous physical activity and total physical activity using tri-axial accelerometer, self-perceived handicap and anxiety using questionnaires, and postural stability were measured using computerized dynamic posturography.
The results showed worse handicap, anxiety and postural stability in the patient group compared to the healthy group. Objective measures of physical activity revealed that the patient group had significantly longer time of sedentary behavior, shorter time of light physical activity, and shorter time of total physical activity compared to the healthy group; however, time of moderate to vigorous physical activity was not significantly different between groups. Moreover, there were correlations between physical activity and postural stability in the patient group, while there were no correlations between physical activity, handicap or anxiety in the patient group.
These results suggest that objectively measured physical activity of the patients with chronic unilateral vestibular hypofunction is lower compared to the healthy adults, and less active patients showed decreased postural stability. However, the details of physical activity and causal effect between physical activity and postural stability were not clear and further investigation is needed.
头晕是普通人群中最常见的症状之一。头晕患者会经历平衡问题和焦虑，这可能导致身体活动水平下降以及日常活动参与度降低。此外，前庭损伤后前庭功能的恢复需要身体活动。尽管有报告称身体活动减少与慢性头晕患者的残疾、焦虑、姿势不稳以及前庭功能恢复降低有关，但这些数据是通过自我报告问卷收集的。因此，慢性头晕患者身体活动的客观数据以及身体活动、残疾、焦虑和姿势稳定性之间的关系尚不清楚。本研究的目的是客观测量慢性头晕患者在日常生活中的身体活动情况，以及与健康成年人相比的残疾、焦虑和姿势稳定性。此外，我们旨在研究慢性头晕患者身体活动、残疾、焦虑和姿势稳定性之间的关系。
28例由单侧前庭功能减退引起的慢性头晕超过3个月的患者（患者组）和28例年龄匹配的社区居住健康成年人（健康组）参与了本研究。使用三轴加速度计测量身体活动量，包括久坐行为时间、轻度身体活动、中度至剧烈身体活动以及总身体活动量；使用问卷测量自我感知的残疾和焦虑；使用计算机化动态姿势描记法测量姿势稳定性。
结果显示，与健康组相比，患者组的残疾、焦虑和姿势稳定性更差。身体活动的客观测量结果显示，与健康组相比，患者组的久坐行为时间明显更长，轻度身体活动时间更短，总身体活动时间更短；然而，两组之间的中度至剧烈身体活动时间没有显著差异。此外，患者组中身体活动与姿势稳定性之间存在相关性，而患者组中身体活动、残疾或焦虑之间没有相关性。
这些结果表明，与健康成年人相比，慢性单侧前庭功能减退患者的客观测量身体活动较低，活动较少的患者姿势稳定性降低。然而，身体活动的细节以及身体活动与姿势稳定性之间的因果关系尚不清楚，需要进一步研究。
