The effect on spine height changes from different combinations of time and angle of static prone hyperextension, and one intervention of dynamic hyperextension was explored.
To explore whether controlled hyperextension would cause an height increase with greater duration than previously shown, and to find an optimal combination of hyperextension angle and duration of the intervention.
Hyperextension is a
Ten subjects were exposed to hyperextension in the prone position for different time periods and with different amounts of hyperextension. The effect was measured using the stadiometer for measurement of spine height changes.
The study showed that time was the most important variable, and also that for a given time, there was an increased recovery with increased angle.
The results indicate that hyperextension can be a beneficial maneuver to unload temporarily the spine after loading and to rehydrate the discs, providing enough time is given for the procedure. The optimal time and angle combination was 20 degrees for 20 minutes because this intervention resulted in the largest recovery that lasted for a relatively long period of time.
探讨静态俯卧过伸不同时间和角度的组合以及动态过伸这一干预措施对脊柱高度变化的影响。
探究控制性过伸是否会在比之前所示更长的持续时间内使身高增加，并找到过伸角度和干预持续时间的最佳组合。
过伸是一种……
10名受试者在俯卧位进行不同时间段和不同过伸量的过伸。使用身高计测量脊柱高度变化来评估效果。
研究表明时间是最重要的变量，并且在给定时间内，随着角度增加恢复也增加。
结果表明，过伸可以是一种有益的操作，在负荷后暂时减轻脊柱负荷并使椎间盘再水化，前提是为该操作提供足够的时间。最佳时间和角度组合是20度持续20分钟，因为这种干预导致最大的恢复，且持续时间相对较长。
