In addition, for pain and disability, the Modified Neck Disability Index
(MNDI) and the Visual Analog Scale (VAS) for the Neck Pain and Disability Scale (NPAD); for measuring the quality of life, the Short Form-36 (SF-36) were applied.
Functional disability was assessed with neck disability Index
(NDI) items score range from 0 to 5, higher score indicated greater disability.
79 (53.02%) patients had moderate disability, 42 (28.18%) had severe disability and 28 (18.79%) had mild disability according to neck disability index
The neck disability index
(NDI) is a commonly used, simple and validated outcome measurement tool, which is available in multiple languages to determine self-assessed disability in patients with neck pain.
Her baseline Neck Disability Index
Total Score was 25/50 suggesting moderate to severe disability.
Participants were eligible for inclusion if they reported no neck pain or neck-related disorders during the previous year, scored <5 points on the Neck Disability Index
(NDI), and demonstrated no signs of cervical pathology during a standardized physical examination .
Disability of the participants, due to back pain (disability) was evaluated, using a Polish version of the Neck Disability Index
(NDI) for the cervical spine, and the Oswestry Disability Index (ODI) for the lumbar spine.

: a systematic review', The Journal of Orthopaedic and Sports Physical Therapy, 39(5), pp.
Then, we explored its validity in a sample of chronic WAD patients by comparing TSK-PM scores with scores on the Neck Disability Index
(NDI), the original TSK, active cervical ranges of motion.

Neck Disability Index
scores decreased similarly in both patient groups.
