Abstract
INTRODUCTION
Despite adequate medical treatment, many young adults with haemophilia develop joint alterations-especially in ankles and knees. Undetected over years, subtle structural changes cause subclinical symptoms, before problems become obvious. To objectify these silent pressure pains, the pressure pain threshold (PPT) can be measured by algometry.
AIM
The aim was to investigate and compare the effect of age on PPTs in asymptomatic ankles and knees between boys and young adults with haemophilia and age-matched controls, in order to gain better knowledge about the alteration of the periarticular structures with increasing age.
MATERIAL AND METHODS
Nineteen persons with haemophilia (PwH; severe or moderate; 8-30 years) and 19 age-matched controls with 'healthy' ankles and knees were recruited. Asymptomatic joints with a Haemophilia Joint Health Score = 0 were included. The PPT was measured on four periarticular points per joint, and the data were analysed with a linear mixed model.
RESULTS
The PPT of the control group increased with age, whereas the PPT of the PwH decreased. The difference in age effect per year in kPa between PwH and controls was as follows: β [95%-CI]: -15.41 [-31.63; 0.79]. Although the result was not statistically significant (p = .08), a clear tendency was shown.
CONCLUSION
The results suggest that subclinical alterations in the periarticular structures of these joints may evolve unnoticed over time. However, further research is warranted to determine whether this observed trend is confirmed in a larger sample and at what age the PPT begins to decrease in PwH compared to controls.
