Purpose:
The purpose of this study was to examine the association between pain sensitivity, central sensitization, and functional disability in adolescents with joint hypermobility.
Design And Methods:
A cross-sectional descriptive design was utilized for this study. A sample of 40 adolescents being evaluated for chronic pain and autonomic nervous system dysfunction were recruited. Subjects were evaluated for pain, function, central sensitization, and sensitivity on pain and touch sensory nerve fiber types. Data were analyzed to detect associations between variables.
Results:
Joint hypermobility had a moderately significant correlation with central sensitization measured by the Central Sensitization Inventory, as well as increased pain sensitivity as evidenced by hypersensitivity of Aδ sensory nerve fibers. The presence of central sensitization was also positively associated with level of functional disability.
Conclusions:
Findings implicate joint hypermobility as a possible antecedent to pain hypersensitivity and central sensitization syndromes that when recognized and addressed effectively may reduce functional disability in those affected.
Practice Implications:
It is important for pediatric nurses that work with adolescents that have chronic pain to understand variables that may impact pain and functional disability in order to develop methods to increase function, reduce pain, and increase perceived quality of life.

Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
01:09Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.
