Trigger finger
Trigger finger, or stenosing tenosynovitis, is a condition where
a finger gets stuck in a bent position, often snapping or locking
when straightening. This happens due to inflammation or thickening of
the tendon sheath in the affected finger, which restricts smooth movement. Common
causes include repetitive gripping, extended hand strain, arthritis, or diabetes. Typical
symptoms involve finger stiffness, pain at the base of the finger, tenderness, and
a clicking or locking sensation when bending or straightening the finger. If
not treated, trigger finger can worsen, leading to permanent stiffness or loss
of function.
Physical therapy serves as an effective, non-surgical
way to manage trigger finger by reducing inflammation, enhancing mobility,
and restoring function. Treatment usually starts with gentle stretching and
range-of-motion exercises to maintain flexibility and avoid stiffness.
