Combined Effect of Underwater Ultrasound and Custom-made Foot Orthotics in Patients With Rheumatoid Arthritis: A Randomised Controlled Trial

This randomised controlled trial aims to investigate the effects of underwater ultrasound therapy and customised foot insoles in RA patients. The study evaluates the effects of the combined use of these two methods on pain, functional status and quality of life. The research aims to contribute to current treatment approaches and to demonstrate the effectiveness of innovative methods to improve the quality of life of RA patients.

Study Overview

Detailed Description

Rheumatoid arthritis (RA) is a chronic inflammatory disease that can cause pain, swelling, limitation of movement and deformities in the joints (Cabrera-Sánchez et al. 2024)(Cabrera-Sánchez et al. 2024). Foot and ankle involvement is quite common in RA patients and this may adversely affect the daily living activities of patients. In addition to pharmacological approaches, physical therapy methods and the use of biomechanical supports are also important in the treatment of RA.

Ultrasound is a physical therapy method used to reduce pain and inflammation and accelerate tissue healing (Király et al. 2021). Underwater ultrasound applications may be more effective in superficial areas and may reduce the risk of damage to sensitive tissues around the joint. On the other hand, customised foot insoles (orthotics) are frequently used to correct foot deformities, eliminate biomechanical imbalances and reduce pain (Gaino et al. 2021).

This randomised controlled trial aims to examine the effects of underwater ultrasound therapy and customised foot insoles in RA patients. The study evaluates the effects of the combined use of these two methods on pain, functional status and quality of life. The research aims to contribute to current treatment approaches and to demonstrate the effectiveness of innovative methods to improve the quality of life of RA patients.
