Lewis SE, Fowler NE. Changes in intervertebral disk dimensions after a loading task and the relationship with stature change measurements.
To test the hypothesis that there would be a linear relationship between overall stature change determined by stadiometry and markers of lumbar disk height loss determined from magnetic resonance imaging (MRI).
The short-term loading response of the lumbar spine was evaluated with both stadiometry and MRI, using a within-subject repeated-measures design. Measures were obtained both before and after 15 minutes of walking wearing a weighted vest (20% of body mass). Stature loss measured on the stadiometer was compared with change in lumbar spine length assessed from the MRI images.
A university laboratory.
Participants (N=13; mean age +/- SD, 28.5+/-5.2y; mean height +/- SD, 1.76+/-0.10m; mean body mass +/- SD, 76.6+/-14.9kg) were invited to take part in the investigation. The group was mixed (9 men, 4 women) and comprised people with no history of low back pain.
Not applicable.
Lumbar spine length assessed via MRI and stature change measured via stadiometry.
A significant height loss was observed over the complete lumbar spine (P<.05), and a significant correlation was found between the decrease in posterior spine length and stature loss (r=.61).
The results were supportive of the use of stadiometry as an indirect measure of changes in intervertebral disk height.
刘易斯·SE，福勒·NE。负荷任务后椎间盘尺寸的变化及其与身高变化测量值的关系。
检验以下假设，即通过身高测量仪测定的总体身高变化与通过磁共振成像（MRI）确定的腰椎间盘高度损失指标之间存在线性关系。
采用受试者内重复测量设计，通过身高测量仪和MRI评估腰椎的短期负荷反应。在穿着加重背心（体重的20%）行走15分钟前后均进行测量。将身高测量仪测量的身高损失与从MRI图像评估的腰椎长度变化进行比较。
大学实验室。
邀请参与者（N = 13；平均年龄±标准差，28.5±5.2岁；平均身高±标准差，1.76±0.10米；平均体重±标准差，76.6±14.9千克）参与调查。该组为混合组（9名男性，4名女性），且均无腰痛病史。
不适用。
通过MRI评估腰椎长度，通过身高测量仪测量身高变化。
整个腰椎观察到显著的身高损失（P <.05），并且后脊柱长度的减少与身高损失之间存在显著相关性（r =.61）。
结果支持使用身高测量仪作为椎间盘高度变化的间接测量方法。
