Design outcomes

Primary

MeasureTime frameDescription
Neck disability index1 monthPatient-completed, condition-specific functional status questionnaire with 10 items including pain, personal care, lifting, reading, headaches, concentration, work, driving, sleeping and recreation. This questionnaire has been designed to give us information as to how your neck pain has affected your ability to manage in everyday life. The NDI can be scored as a raw score or doubled and expressed as a percent. Each section is scored on a 0 to 5 rating scale, in which zero means 'No pain' and 5 means 'Worst imaginable pain'. Points summed to a total score. The test can be interpreted as a raw score, with a maximum score of 50, or as a percentage. 0 points or 0% means: no activity limitations, 50 points or 100% means complete activity limitation. A higher score indicates more patient-rated disability.
