L4–L5 range of motion (in degrees), corresponding to a moment of 8 Nm in flexion and 6 Nm in extension, ±6 Nm in lateral bending, and ±5 Nm in axial rotation.

Abbreviations:FE = Flexion-Extention.MI –D = Minimally invasive decompression.TD = Traditional decompression.WTD = Wide traditional decompression.(SD) = Standard deviation.(*denotes statistically significant difference from the intact condition;†denotes statistically significant difference from the MI-D condition).The values in parentheses denote one standard deviation of the mean.缩略语说明：FE即屈伸（Flexion-Extention）；MI-D即微创减压术（Minimally invasive decompression）；TD即传统减压术（Traditional decompression）；WTD即广泛传统减压术（Wide traditional decompression）；(SD)即标准差（Standard deviation）。*代表与完整状态存在统计学显著性差异；†代表与MI-D组存在统计学显著性差异。括号内的数值为均值的一个标准差。
