OBJECTIVE
We investigated the changes of the vestibulospinal tract (VST) and parietoinsular vestibular cortex (PIVC) using diffusion tensor imaging (DTI) and relation to balance between old and young healthy adults.
METHODS
This study recruited eleven old adults (6 males, 5 females; mean age 63.36 ± 4.25 years) and 12 young adults (7 males, 5 females; mean age 28.42 ± 4.40 years). The lateral and medial VST and PIVC were reconstructed using DTI. Fractional anisotropy (FA), mean diffusivity (MD), and tract volume were measured. The six-minute walk test (6-MWT), the timed up and go test (TUG), and the Berg balance scale (BBS) were conducted. Spatiotemporal parameters during tandem gait and values of sway during one-leg standing using the wearable sensors were measured. All parameters between two groups were analyzed by the Mann-Whitney test and independent -test.
RESULTS
Statistically significant decrease in old adults was detected in the tract volume of lateral ( = 0.005) and medial VST ( = 0.005) and medial VST ( = 0.005) and medial VST ( = 0.005) and medial VST ( = 0.005) and medial VST ( = 0.005) and medial VST ( = 0.005) and medial VST ( = 0.005) and medial VST ( = 0.005) and medial VST ( = 0.005) and medial VST ( = 0.005) and medial VST ( = 0.005) and medial VST ( = 0.005) and medial VST ( = 0.005) and medial VST ( = 0.005) and medial VST (.
CONCLUSION
The results suggested that there was a relationship between DTI parameters in the vestibular neural pathway and balance according to aging.
目的
我们通过弥散张量成像（DTI）研究前庭脊髓束（VST）和顶内前庭皮质（PIVC）的变化，并将其与老年和年轻健康成年人之间的平衡联系起来。
方法
本研究招募了 11 名老年成年人（6 名男性，5 名女性；平均年龄 63.36 ± 4.25 岁）和 12 名年轻成年人（7 名男性，5 名女性；平均年龄 28.42 ± 4.40 岁）。使用 DTI 重建外侧和内侧 VST 和 PIVC。测量各向异性分数（FA）、平均扩散系数（MD）和束流体积。进行 6 分钟步行测试（6-MWT）、计时起立行走测试（TUG）和伯格平衡量表（BBS）。使用可穿戴传感器测量串联步态的时空参数和单腿站立时的摆动值。使用 Mann-Whitney U 检验和独立样本 t 检验对两组间的所有参数进行分析。
结果
与年轻成年人相比，老年成年人的外侧（ = 0.005）和内侧 VST（ = 0.005）和内侧 VST（ = 0.005）和内侧 VST（ = 0.005）和内侧 VST（ = 0.005）的束流体积明显减少，差异有统计学意义。（ = 0.005）和内侧 VST（ = 0.005）和内侧 VST（ = 0.005）和内侧 VST（ = 0.005）和内侧 VST（ = 0.005）和内侧 VST（ = 0.005）和内侧 VST（ = 0.005）和内侧 VST（ = 0.005）和内侧 VST（ = 0.005）和内侧 VST（ = 0.005）和内侧 VST（ = 0.005）和内侧 VST（ = 0.005）和内侧 VST（ = 0.005）和内侧 VST（ = 0.005）。
结论
结果表明，前庭神经通路的 DTI 参数与年龄相关的平衡之间存在关系。
