Age Moderates the Relationships between Family Functioning and Neck Pain/Disability.

This cross-sectional clinical study was designed to explore the relationships between family functioning, coping styles, and neck pain and neck disability. It was hypothesized that better family functioning and more effective coping styles would be associated with less pain and pain-related disability. It also was hypothesized that these relationships would be stronger in older people because they have fewer resources, more limited coping styles, and may depend more on their family for support.

The role of selected variables in the diagnosis of cervical derangement syndromes.

Background: The study analyzed correlations between selected variables in cervical derangement syndromes.

Material And Methods: We analyzed data from 63 patients regarding pain (VAS, McGill Pain Questionnaire), mobility (CROM goniometer), dizziness, nausea, the duration of the current episode, and the number of previous episodes (history). Student's t and chi(2) tests and Pearson's r correlation were used.

Purpose: Psychometric validation of the authorized Polish version of the Neck Disability Index (NDI).

Methods: Ninety-five patients with neck pain were enrolled. Reliability was assessed through Cronbach's alpha, split-half reliability, intra-class correlation (ICC) and agreement between measures with limits of agreement using the interval of 48 hours.
