Plus-minus values are means ± SD unless otherwise noted.
Stage of the disease is divided according to duration of the low back pain symptoms first appeared of this time, acute stage (0~14 days), subacute stage (15~30 days), and chronic stage ( 30 days).
#Visual analogue scale (VAS, range 0 to 100) with higher scores indicating greater pain.
&Based on imaging examination to determine the segments of lumbar disc herniation; L3/L4 means disc herniation between the third and fourth lumbar, and the others are the same.
The Chinese Short Form Oswestry Disability Index (C-SFODI, range 0 to 100%) consists of 9 questions. A higher percentage indicates a more severe functional disability.
