Gout patients who make poor footwear choices experience higher foot-related pain, impairment and disability, a new study found.
New research shows that use of poor footwear is common among patients with gout. According to the study published today in Arthritis Care & Research, a peer-reviewed journal of the American College of Rheumatology (ACR) gout patients also reported that comfort, fit, support and cost were the most important factors for selecting footwear.
Gout is a type of inflammatory arthritis caused by the crystallization of uric acid within the joints and other tissues. Those with gout experience severe pain and swelling, with the majority of cases affecting the feet. A study published last month in the ACR journal, Arthritis & Rheumatism, shows that doctor-diagnosed gout has risen over the past twenty years and now affects 8.3 million individuals in the U.S. Previous studies have shown that chronic gout contributes to changes in patients' gait parameters, which is consistent with pain avoidance strategy, and likely leads to impaired foot function.
A research team led by Professor Keith Rome from AUT University in Auckland, New Zealand, recruited 50 patients with a history of gout from local rheumatology clinics. Researchers assessed clinical disease characteristics, overall function, foot impairment and disability. The type of footwear worn by patients and factors associated with patient choice of footwear were also evaluated. To determine the suitability of footwear, the team used criteria gauging the adequacy of the footwear from a previous rheumatoid arthritis foot pain study.
