Twice a day, exercise for at least 30 minutes. Measurement tools include the visual analog scale(VAS) and Oswestry Disability Index (ODI).

Results: Both the WE and ME groups showed a statistically significant decrease in VAS and ODI scores. In thecase of ODI, the ME group showed more effect. In detail, the WE group had a greater exercise effect on the¡®standing¡¯ and ¡®walking¡¯ items, and the ME group had a greater exercise effect on the ¡®sitting¡¯ and ¡®sleeping¡¯ items.
