Use of a temporary supramalleolar orthosis to manage foot pain in a patient with rheumatoid arthritis: A case report.

Background: Rheumatoid arthritis is a chronic inflammatory condition characterized by joint pain, stiffness, and functional disability. Approximately 90% of patients will report symptoms in the foot or ankle during the course of their disease.

Case Description: A case of a 40-year-old woman with a 12-year history of rheumatoid arthritis referred to outpatient physical therapy with a chief complaint of pain in the lateral rearfoot and forefoot is presented. At the time of the initial examination, the patient reported persistent pain ranging from 3 to 9/10, aggravated when standing and walking during activities of daily living. Treatment consisted of the fabrication of a supramalleolar orthosis that incorporated an in-shoe foot orthosis to address functional limitations and abnormal foot and ankle posture. A home exercise program was prescribed to address potential balance deficits and strength loss following the application of the orthosis.

Outcomes: Clinically significant improvements were seen in pain, gait speed, and on the Foot Function Index following the implementation of the orthotic device. The patient returned to standing and walking with minimal symptom limitations.

Discussion: This case report highlights the short-term clinical outcomes when using a supramalleolar orthosis in conjunction with an in-shoe foot orthosis to manage lateral rearfoot and forefoot pain in a patient with rheumatoid arthritis.
