| Oswestry Disability Index (ODI) at baseline | using Oswestry questionnaire version 1.0 - Thai version The ODI is comprised of 10 questions that ask patients about their ability to manage everyday life, and covers intensity of pain, lifting, ability to care for oneself, ability to walk, ability to sit, sexual function, ability to stand, social life, sleep quality, and ability to travel. Each question contains 6 statements that correlate to a score of 0 through 5, where the patient is to choose the statement that best matches their ability. To obtain the index, the scores of all questions are summed and then multiplied by two. The final score/index ranges from 0-100. A score of 0-20 reflects minimal disability, 21-40 moderate disability, 41-60 severe disability, 61-80 crippled, and 81-100 bed-bound. |
