Description

The Neck Disability Index (NDI) is an assessment tool used to evaluate the disability related to neck problems. It assesses the impact of cervical dysfunction on the individual’s daily life, including work, social life, and everyday activities.

Analysis and Use of Data

Data analysis from the Neck Disability Index includes:

Scoring: Questions are typically rated on a Likert scale, where participants select scores reflecting their difficulty with various activities.

Statistical Analysis:

Descriptive Statistics: The mean and standard deviation are calculated to determine the overall disability level.

Correlation: The correlation of disability with factors such as age, gender, and severity of symptoms is examined.

Comparative Analysis: Comparisons between different groups, e.g., patients with different conditions or therapeutic approaches.

Objective

The objective of the Neck Disability Index is to provide a reliable method for assessing disability related to the cervical region, in order to guide therapeutic intervention and rehabilitation. Through assessment, healthcare professionals can better understand patients’ needs and monitor their progress.

Calibration

Calibration of the Neck Disability Index involves the process of adapting the tool for different populations and their needs. This is achieved through:

Cross-Cultural Studies: Testing the NDI in different cultures to ensure its validity.

Reliability Analysis: Using techniques such as Cronbach’s alpha to evaluate the consistency of the questions.

Validity Testing: Assessing the ability of the NDI to reflect the real experiences of individuals with neck problems.
