How the ODI Works
The Oswestry Disability Index (ODI) is a self-administered questionnaire that assesses the impact of low back pain on a patient’s ability to perform daily activities․ It consists of 10 sections‚ each focusing on a different aspect of functional ability․ These sections cover a range of activities‚ including personal care‚ lifting‚ walking‚ sitting‚ standing‚ sleeping‚ sex‚ social life‚ and travel․ Each section presents a series of statements that describe varying levels of difficulty or impairment․
Patients are asked to select the statement that best reflects their current condition‚ indicating the level of difficulty or impairment they experience in each activity․ The scoring system assigns numerical values to each statement‚ with higher scores reflecting greater disability․
The total score for all 10 sections is calculated‚ resulting in a percentage score that represents the overall level of disability․ This percentage score provides a quantitative measure of the functional impact of low back pain‚ allowing for objective comparisons across individuals and over time․
Sections of the ODI
The Oswestry Disability Index (ODI) is divided into 10 sections‚ each focusing on a specific aspect of functional ability․ These sections are designed to comprehensively assess the impact of low back pain on a patient’s daily life․
The sections of the ODI are as follows⁚
- Pain Intensity⁚ This section assesses the severity and frequency of pain experienced by the patient․
- Personal Care⁚ This section explores the patient’s ability to perform basic self-care tasks such as dressing‚ bathing‚ and grooming․
- Lifting⁚ This section assesses the patient’s ability to lift objects of varying weights․
- Walking⁚ This section evaluates the patient’s ability to walk different distances and terrains․
- Sitting⁚ This section explores the patient’s ability to sit for varying durations and engage in seated activities․
- Standing⁚ This section assesses the patient’s ability to stand for varying durations and engage in standing activities․
- Sleeping⁚ This section explores the patient’s sleep quality and the impact of pain on their sleep․
- Sex⁚ This section assesses the impact of pain on the patient’s sexual function (if applicable)․
- Social Life⁚ This section explores the patient’s ability to participate in social activities and interactions․
- Travel⁚ This section assesses the patient’s ability to travel by different means of transportation․
Each section presents a series of statements describing varying levels of difficulty or impairment․ Patients are asked to select the statement that best reflects their current condition․
Scoring the ODI
Scoring the Oswestry Disability Index (ODI) involves assigning numerical values to each section based on the patient’s chosen response․ Each section has a possible score range of 0 to 5‚ with 0 representing no disability and 5 representing the highest level of disability․
The scoring system is designed to reflect the increasing severity of functional limitations․ For example‚ in the “Pain Intensity” section‚ a patient who selects the statement “I can tolerate the pain I have without having to use pain medication” would receive a score of 0‚ while a patient who selects the statement “The pain is severe and does not vary much” would receive a score of 5․
After scoring each of the 10 sections‚ the scores are summed to obtain a total ODI score․ This total score is then divided by 50 (the maximum possible score) and multiplied by 100 to calculate the final percentage score․ The final percentage score represents the overall level of disability experienced by the patient due to low back pain․
A higher ODI score indicates a greater level of disability․ Scores can range from 0% (no disability) to 100% (complete disability)․ The ODI is a valuable tool for assessing changes in functional status over time‚ monitoring treatment progress‚ and evaluating the effectiveness of interventions․
