Trigger finger exercises, which occur when the finger flexes suddenly, serve to strengthen the extensor muscles of the hand, especially the affected finger, counteracting the natural movement the trigger finger makes.
These exercises are important because normally the flexor muscles, responsible for folding the fingers, become stronger, while the extensors become weaker, causing a muscle imbalance.
Before these exercises, you can massage the affected joint to facilitate blood flow and help lubricate the joint by gently rubbing the joint through circular motions for 2 to 3 minutes.
So, some trigger finger exercises can be:
Exercise 1
Place the hand with the affected finger on a flat surface and lift the affected finger as far as it will go, maintaining the stretching for 30 seconds, as shown in the image. Repeat the exercise 3 to 5 times.
Exercise 2
Put an elastic around your fingers in forcing your fingers to open the hand, stretching the elastic. Slowly return to the starting position and repeat the exercise about 10 to 15 times.
Exercise 3
Put the dough under your hand and try to stretch it, keeping your fingers straight, as shown in the picture. Do this exercise for 2 minutes.
The exercises should be performed slowly and when the individual starts to feel pain should stop. To relieve the stiffness of the hand, warm the tendons and help stretch the finger, you can place your hand in a bowl of warm water.
