Validation of Telephone-Based Application of Neck Disability Index and Mandibular Functional Limitation Index (pubmed.ncbi.nlm.nih.gov)

• Telephone-administered NDI and MFLI are valid and reliable
• Strong agreement between telephone and face-to-face scores
• Supports telerehabilitation for neck and TMD patients

"This study validates the telephone-based application of the Neck Disability Index (NDI) and Mandibular Functional Limitation Index (MFLI) for assessing neck and jaw dysfunction. Results indicate that telephone administration is reliable and valid, supporting its use in telerehabilitation. Clinicians can confidently use these tools for remote assessment, improving access to care for patients with limited mobility or distance barriers."
