Development of a Novel Stocking for Foot Sole Pain in Patients with Rheumatoid Arthritis
Background: We sought to investigate the clinical efficacy of the Fuß-sole (Kuroda, Osaka, Japan), a newly developed stocking, in patients with severe foot pain attributable to rheumatoid arthritis. Methods: The Fuß-sole stocking incorporates a plantar insole made of breathable fabric. Twenty patients with rheumatoid arthritis and severe foot pain were enrolled in this study. Clinical efficacy was evaluated using the Japanese Orthopaedic Association's foot-scoring system. Outcome measures were evaluated before and after a 1-month trial of the Fuß-sole stocking. Results: Use of the Fuß-sole stocking resulted in significant improvements in foot pain, activities of daily living, and total scores. Conclusions: Use of the Fuß-sole improves the quality of life of patients with rheumatoid arthritis. (J Am Podiatr Med Assoc 100(1): 10–13, 2010)
