Trigger finger — medically known as stenosing tenosynovitis — is a condition where one of your fingers gets stuck in a bent position and may snap or pop when you try to straighten it. This frustrating condition affects roughly 2-3% of the general population, with higher rates among people with diabetes, women over 40, and those whose work involves repetitive gripping. Physical therapy provides effective non-surgical treatment that can resolve trigger finger and restore normal hand function.
What Causes Trigger Finger?
Your finger tendons glide through a series of pulleys — small tunnels of tissue that hold the tendon close to the bone. Trigger finger develops when the tendon sheath (the protective covering around the tendon) becomes inflamed and thickened, narrowing the space within the pulley. As the tendon tries to glide through this narrowed space, it catches and clicks. In severe cases, the finger becomes locked in the bent position and must be manually straightened.
Risk factors include repetitive hand use (particularly forceful gripping), diabetes, rheumatoid arthritis, gout, and hypothyroidism. The ring finger and thumb are most commonly affected, though any finger can develop the condition. Many patients develop trigger finger in multiple fingers over time.
Physical Therapy Treatment Options
Splinting
Your physical therapist may recommend a custom or prefabricated splint that holds the affected finger in a straight position, particularly at night. This prevents the finger from curling during sleep, which often causes the worst morning stiffness and locking. Splinting for six weeks resolves trigger finger in approximately 50-70% of mild to moderate cases.
Tendon Gliding Exercises
Specific exercises that move the tendon through its full range of motion help reduce adhesions and improve gliding within the tendon sheath. Your therapist will teach you a series of hand positions — straight, hook, fist, tabletop, and straight fist — that systematically mobilize the flexor tendons. These exercises are typically performed multiple times throughout the day.
Manual Therapy
Soft tissue mobilization along the affected tendon and pulley system helps reduce inflammation and improve tendon mobility. Your therapist may also use instrument-assisted soft tissue mobilization or massage techniques to address tightness in the hand and forearm muscles that contribute to increased tendon tension.
Activity Modification
Identifying and modifying the activities that aggravate your trigger finger is essential for recovery. Your therapist will evaluate your work tasks, hobbies, and daily routines, then recommend modifications such as using ergonomic tools, padded grips, or alternate hand positions that reduce stress on the affected tendon. For those who spend long hours gripping tools or devices, an ergonomic grip adapter can make a noticeable difference in symptom management.
When to Consider Other Options
If physical therapy alone doesn’t fully resolve your trigger finger after six to eight weeks, your therapist may recommend discussing corticosteroid injections with your physician. These injections are effective in 60-90% of cases, particularly when combined with ongoing physical therapy. Surgery is typically reserved for severe or recurrent cases that don’t respond to conservative treatment.
Most cases of trigger finger respond well to conservative treatment — the key is catching it early before the condition becomes chronic.
