Spine Outcome Measurements: Spine Function Index-10

The Spine Function Index-10 (SFI-10) is a self-report questionnaire that measures the level of functional limitation in individuals with low back pain. The SFI-10 consists of 10 items that assess the individual's ability to perform everyday activities, such as bending, lifting, walking, and standing.

The SFI-10 can be used in clinical and research settings to evaluate the impact of low back pain on functional ability and to monitor changes in functional status over time. It is appropriate for use in individuals with acute or chronic low back pain, as well as those undergoing rehabilitation for low back pain.

The SFI-10 is relatively quick and easy to administer, making it a convenient tool for clinicians to use in routine clinical practice. It can also be used in combination with other measures of pain and disability to provide a comprehensive assessment of the impact of low back pain on an individual's health status.

Overall, the SFI-10 is a useful tool for assessing functional status in individuals with low back pain and can provide valuable information for guiding treatment and rehabilitation efforts.

The SFI-10 is scored on a scale of 0-10, with higher scores indicating greater functional limitation. A score of 0 indicates no functional limitation, while a score of 10 indicates severe functional limitation.

Interpretation of SFI-10 scores should take into account the individual's specific context and functional goals. However, in general, scores can be interpreted as follows:

• 0-3: Mild functional limitation
• 4-6: Moderate functional limitation
• 7-10: Severe functional limitation
