Objective
[edit | edit source]

The NDI is a modification of the Oswestry Low Back Pain Disability Index  www.physio-pedia.com/index.php5. It is a patient-completed, condition-specific functional status questionnaire with 10 items including pain, personal care, lifting, reading, headaches, concentration, work, driving, sleeping and recreation. The NDI has sufficient support and usefulness to retain its current status as the most commonly used self-report measure for neck pain [1]. 

The NDI is translated in many languages (greek, german, dutch, Korean, Spanish, frensh…) each has its own validity and reliability outcomes. Because there is an impact of translation on validity.
The NDI can be used for evaluating the patients status praeses and evolution during the therapy (intended population).[2]

Intended Population[edit | edit source]

Chronic neck pain, musculoskeletal neck pain and whiplash injuries.

Method of Use
[edit | edit source]

The NDI can be scored as raw score [1]or doubled, and expressed as a percent [2]. Each section is scored on a 0-5 scale, with the first statement being “0” (ie. No pain) and the last statement being “5” (ie. Worst imaginable pain). Al the points are than summed. Interpretation of the test can be numeric form 0 points to 50 points. It can also be calculated in percentages.
0 points or 0% means : no activity limitations ,
50points or 100% means complete activity limitation.

A higher score indicates more patient-rated disability. There is no statement in the original literature on how to handle missing data. To use the NDI for patient decisions, a clinically important change was calculated as 5 points, with a sensitivity of 0.78 and a specificity of 0.80[3].

Mean duration of the test: 3 to 7.8 minutes
Some benchmarks can be found in literature but methodologically they were not described and theire validity and reliability are questionable Vernon and Moir presented the following interpretation:
• 0-4points (0-8%) no disability,
• 5-14points ( 10 – 28%) mild disability,
• 15-24points (30-48% ) moderate disability,
• 25-34points (50- 64%) severe disability,
• 35-50points (70-100%) complete disability

Responsiveness[edit | edit source]

The NDI appears to demonstrate adequate responsiveness in patients with neck pain and concomitant upper extrmity referred symptoms[5]. Young et al [5] suggest that a 10-point change should be used as the minimum clinically important difference.
