The aim of trigger finger exercises is fourfold:
* to counteract the constant flexing of the joint
* to strengthen muscles
* to maintain the full range of movements in the affected digit
* to restore the tendon’s gliding movement.
Soaking your hand in warm water and massaging it before commencing exercises will warm it up and loosen the muscles and tendons.
These exercises help maintain the range of movement of the finger. Passive exercise means that the affected finger itself does not do the moving. Movements should never be forced. You use the other hand to bend, rotate and straighten the affected finger through its widest possible range of movements without causing pain. Repeat the movements10 to 15 times three times a day or more often.
When you stretch your finger, the movement is the exact opposite of the trigger position. This counteracts the persistent movements that were the possible cause of the trigger finger. Stretching the finger will keep it as flexible as possible. You can do the exercise both actively (the finger moving itself) and passively. For the passive stretching exercises, use your other hand and pull the affected finger backwards beyond extension until you experience the stretch in the palm of your hand at the base of the finger. Hold the position for about 10 seconds and repeat a sequence of 5. Repeat the exercise frequently.
Exercises to Strengthen Muscles:
Each muscle in our body is paired with another muscle that performs the exact opposite movement. Trigger finger is caused by overuse of flexor muscles. The opposite, extensor muscles, will probably be weak due to lack of use. Strengthening the extensor muscles often helps trigger finger.
1.You will need a fairly strong rubber band for a simple exercise to strengthen the extensor muscles in your hand. Wrap the rubber band round the tips of your fingers and thumb on the affected hand. Working against the resistance of the rubber band, open your fingers and thumb as far away from each other as possible. Hold the position for a few seconds then allow them to slowly relax back together. Repeat 15 times 2 or 3 times daily.
2. Finger abduction exercise. Straighten the affected finger and the finger next to it. Hold the two fingers fairly firmly together with the thumb and forefinger of your other hand. Try moving the two fingers apart against the resistance. Hold the position for a few seconds, then relax.
3. Opposite abduction exercise. Hold your affected finger and the one next to it apart in a “V”. Push the two fingers together with the thumb and forefinger of the other hand while trying to resist the movement with your affected fingers.
4. Finger-thumb touches: touch the pad of your thumb with each fingertip
Tendon Gliding Trigger Finger Exercises:
Close your hand into a fist keeping your wrist straight, hold the position for a few seconds then fully extend the fingers. Repeat a few times.
Repeat the sequence with the hand in the “hooked” position 90 degrees to your arm.
These exercises will encourage the tendons to glide freely.
Trigger finger exercises will improve trigger finger problems and might cure the condition completely. They will also maintain finger movement and flexibility.
