Trigger finger, a common hand condition, can make simple daily activities challenging due to impaired finger movement. Tendon glides offer a non-surgical approach to managing the discomfort and stiffness associated with this condition. These gentle exercises are designed to help restore smoother motion to the affected finger.
What is Trigger Finger
Trigger finger, medically known as stenosing tenosynovitis, occurs when a finger tendon or its surrounding sheath becomes inflamed or narrowed. This condition often affects the A1 pulley, a fibrous band located at the base of the finger near the palm. The flexor tendons, which control finger bending, must glide smoothly through these pulleys. When the sheath or pulley thickens, the tendon can catch as it tries to move.
Common symptoms include a catching or locking sensation when bending or straightening the finger. Individuals may also experience pain at the base of the finger, stiffness, and a popping sound or feeling. The finger might become locked in a bent position, requiring manual straightening.
How Tendon Glides Work
Tendon glides are targeted exercises designed to improve the smooth passage of the flexor tendons through their sheaths. These movements encourage the tendon to move more freely within the constricted A1 pulley. The repetitive, gentle motion helps to reduce friction and can potentially decrease localized inflammation and swelling within the tendon sheath.
Regular performance of these exercises helps maintain the flexibility and mobility of the finger joints and tendons. The goal is to encourage the tendon to glide without resistance, alleviating the characteristic symptoms of trigger finger and preventing catching or locking.
Step-by-Step Tendon Glides
Performing tendon glides involves a sequence of specific hand positions to encourage full tendon movement. Begin by extending your fingers straight out, palms facing you, forming a relaxed, open hand. This is your starting position for each exercise.
Next, form a “straight fist” by bending only the tips of your fingers, keeping the middle and knuckle joints straight. Hold this position briefly before returning to the open hand. Follow this with a “hook fist,” where you bend only the knuckles and middle finger joints, allowing the fingertips to remain extended.
Transition to a “tabletop fist” by bending your fingers at the knuckles and middle joints so your fingertips touch your palm, but your palm remains open. From there, create a “full fist” by curling all your fingers tightly into your palm, ensuring your thumb rests outside your curled fingers. Finish the sequence with a “reverse fist,” extending your fingers fully and gently arching them backward at the knuckles. Perform each position slowly and deliberately, holding for 3-5 seconds. Aim for 10-15 repetitions of the full sequence, completing several sets throughout the day.
Important Considerations and When to Seek Help
Consistency is important for better results when performing tendon glides. Always perform these exercises gently, without forcing any movement that causes increased pain. If you experience sharp or worsening pain, stop immediately. Listening to your body helps prevent further irritation to the tendon and sheath.
These exercises are often part of a broader management strategy, which might include rest, splinting, or anti-inflammatory measures. If your symptoms worsen, if there is no improvement after several weeks of consistent exercise, or if your finger remains locked, it is advisable to consult a healthcare professional. A doctor can assess your condition and recommend appropriate further treatments, which may include injections or surgical options.
