1. What is the Back Pain Index?

The Back Pain Index is a standardized measure used to quantify the severity and impact of back pain on a patient's daily life. It provides a percentage score that helps healthcare professionals assess treatment effectiveness and monitor progress over time.

2. How Does the Calculator Work?

The calculator uses the Back Pain Index formula:

\[ Index = \frac{\text{Sum Scores}}{\text{Max Score}} \times 100 \]

Where:

\( Sum Scores \) — Total points scored on the assessment questionnaire
\( Max Score \) — Maximum possible score on the assessment
\( Index \) — Resulting percentage indicating back pain severity

Explanation: This formula converts raw questionnaire scores into a standardized percentage, making it easier to compare results across different assessment tools and track changes over time.

3. Importance of Back Pain Index

Details: The Back Pain Index is crucial for objectively measuring pain severity, monitoring treatment response, and making informed decisions about pain management strategies. It helps standardize pain assessment across different healthcare settings.

4. Using the Calculator

Tips: Enter the sum of all scores from your back pain assessment and the maximum possible score for that assessment. Ensure sum scores do not exceed maximum score. All values must be positive numbers.
