Trigger finger, also known as stenosing tenosynovitis, is a condition that affects the fingers and thumb. It occurs when the tendons in the fingers become inflamed or irritated, causing the finger or thumb to get stuck in a bent position or snap suddenly when straightened. This condition is characterized by pain, stiffness, and a popping or clicking sensation when moving the affected finger or thumb.
The exact cause of trigger finger is not always clear, but it is often associated with repetitive hand and finger movements, such as gripping or grasping activities. Certain factors, such as diabetes, rheumatoid arthritis, and previous hand injuries, may increase the risk of developing trigger finger. Symptoms usually worsen over time, and in severe cases, the finger may remain locked in a bent position and require manual straightening.
Manual Therapy Techniques: Physical therapists use hands-on techniques, such as joint mobilization and soft tissue mobilization, to improve the mobility of the affected finger or thumb. These techniques help in reducing inflammation, breaking up scar tissue, and restoring normal tendon function. Manual therapy can also enhance blood circulation and promote healing.
Education and Ergonomic Advice: Physical therapists provide education on proper hand and finger positioning during activities to minimize strain and prevent exacerbation of symptoms. They may offer ergonomic advice, such as recommending adaptive tools or modifications to workstations, to reduce repetitive movements and protect the fingers from further irritation.
