What does DI stand for?

Outcome measures included the Oswestry Disability Index and several functional tests and were measured before and after intervention.

The inclusion criteria required patients to be between the ages of 18-65 years, with a primary report of neck pain with or without unilateral upper extremity symptoms, and a baseline Neck Disability Index (NDI) score of at least 10%.

During the Portuguese study's three month period, the researchers observed a 33 percent improvement in the HAQ (Health Assessment Questionnaire) disability index measurement of physical functioning (assessing ability to undertake everyday activities such as dressing, eating and walking, and whether assistance from another person or disability aids is required).

Pain/Disability Level Subject pain/disability was inferred from self-reported scores on the Oswestry Disability Index (ODI), which was given to each subject during the initial testing sessions.

The Oswestry Disability Index allowed the patients to project their perceived disability with an objective measure.

One item in the survey instrument Kinney and Benninger used (a modified Rhinosinusitis Disability Index questionnaire) requires one of five multiple-choice responses (ranging from never to always) to the statement: "Because of my problem I feel fatigued" Contrasting the results between the AR and the CRS group might offer insight into the cause of nasal- and sinus-related fatigue.

The HAQ disability index in this study showed a mean improvement of about 0.
