CORRELATION BETWEEN CLINICAL VARIABLES IN HIP OSTEOARTHRITIS
Abstract:
Osteoarthritis is the most common joint disorder and has an important impact on patients’
quality of life. We aimed at establishing the correlations between several parameters: pain, functional
impact and disability, but also the relationships between these parameters and age or disease duration
in hip osteoarthritis patients. We evaluated 144 patients, all Caucasians, with hip osteoarthritis treated
in the Emergency Hospital “Avram Iancu”, from Oradea, Romania. All the patients followed a
rehabilitation programme for 12 days, repeated after 6 months and 1 year. We performed four
evaluations: at admission, before patients started the rehabilitation programme, at discharge, after 6
months and after 1 year, using VAS pain scale, Lequesne functional index and HAQ index. SPSS
statistics was used. There were high correlations, statistically highly significant between age and disease
onset, age and disability, assessments at admission, discharge, 6 months and 1 year. Age correlated
moderately, but statistically highly significantly with functional impact established at admission in the
hospital and at discharge. Both age and disease onset poorly correlated, but statistically significantly,
with pain. Correlation of pain with disability was low at admission, but highly statistically significant.
Disability assessed by HAQ and patients’ age were strongly correlated, showing that with age the
quality of life in hip osteoarthritis cases deteriorates. Correlations of clinical and functional variables
with duration of disease were of different intensities, most closely relationship was obtained with
functional impact, confirming that progression of anatomo-pathological phenomena interfere with
occupational activities.
