Context:
Evidence suggests that central sensitization (CS) may contribute to pain in osteoarthritis (OA) knee patients, which cannot be treated by locally directed treatment strategies.
Aims:
The aim of this study was to examine differences in demographic profile of patients with and without central sensitization in osteoarthritis knee.
Settings And Design:
Observational cross-sectional study at tertiary care hospital.
Materials And Methods:
The study was conducted in the Department of Physical Medicine and Rehabilitation, VMMC and Safdarjung Hospital in 345 OA knee patients. Demographic profiles including age, gender, education, occupations, type of family, marital and socioeconomic status and central sensitization were assessed. The association between CS and various demographic parameters was investigated.
Statistical Analysis Used:
Statistical Package for Social Sciences (SPSS) software, IBM manufacturer, Chicago, USA, version 21.0. For statistical significance, P value of less than 0.05 was considered statistically significant.
Results:
Ninety out of 345 (26%) of study subjects had CS; out of which 96% were females. Younger homemaker and those with unskilled/semiskilled type of job had higher chances of having CS in comparison with those with skilled and professional job (P < .001).
Conclusions:
Elicitation of specific demographic factors that can predict CS in people with knee OA may help in early identification and management of CS in OA knee patients.
