[Insoles for the rheumatic foot. A clinical and pedobarographic analysis].
BACKGROUND
Insoles are regarded as an appropriate tool for the management of rheumatic foot disorders. However, a quality control for this purpose has not been established. In our study, the clinical effectiveness of insoles used in patients with rheumatic foot disorders was addressed. In addition, we sought to establish pedobarography as a means of quality control for orthotic management of the rheumatic foot.


METHODS
Our study included 20 rheumatoid arthritis patients with painful rheumatic foot deformities who were provided with insoles. Clinical data were obtained by physical examination and a 100-mm pain scale. Pedobarography was performed using the novel pedar cable system with new and individually designed insoles and after a 6-month follow-up. A shoe-only trial served as control. The parameters maximum force, peak pressure, force-time integral, and average pressure were analyzed in anatomical regions and an individually defined overloaded forefoot region.


RESULTS
Clinical improvement was significant after a 6-month follow-up in spite of a heterogeneous group of patients. However, our results could not confirm consistent changes in plantar pressure distribution.


CONCLUSIONS
As a conclusion, further efforts are necessary to establish a quality control for orthotic management of the rheumatic foot.
