Trigger Finger Exercises For Pain And Stiffness

Trigger finger is a condition that affects the tendons in the fingers, causing a painful snap or lock when attempting to bend and straighten affected fingers.

The fingers that are commonly affected are the ring finger and the thumb.

Tendons connect muscles to bones. They have soft tissue that covers them to allow for easy movement. This soft tissue is known as the tendon sheath.

When these tendons get irritated or inflamed in the sheath, the tendons do not move about easily and this causes the catching and locking sensation that is known as trigger finger.

Exercises For Trigger Finger

You should discuss with your doctor before exercising a trigger finger. This is to be sure that it is appropriate for your particular case. Exercises will involve stretching the tendons that have been affected. Some of these exercises are:

1. Finger To Thumb Circle Stretch

    • Take your index finger to the pad of the thumb to form a circle
    • Apply a little pressure on the finger using your thumb to stretch the finger
    • Repeat this on the other fingers
    • Do this up to ten times

2. Grip Strength

      • Using a softball or a rolled-up towel, squeeze the ball and towel 10 times
      • Hold each squeeze for 10 seconds

3. Rubber Band Stretch

    • Place a rubber band or a hair grip around your fingers
    • Open up your fingers to stretch out the band
    • Hold for 5 seconds
    • Relax your fingers

4. Finger Extensor Stretch

    • Place your palm flat on a table
    • Use your other hand to slowly lift the affected finger off the table
    • Pull the finger as high as it can go without straining it
    • Hold the pull for 5 seconds
    • If other fingers are affected, do the same as well

5.Finger Stretches

    • Place your palm with the affected finger flat on the table
    • Spread your fingers out wide
    • Hold for 5 seconds
    • Then squeeze your fingers together for a few seconds
    • Use your other hand to bend your fingers backward and forward
    • This can be done 2 – 4 times in a day

6. “V” Stretch

    • Move the affected finger away from its neighbor finger
    • To go deeper into the stretch use your index finger and thumb finger, on the other hand, to stretch them further
    • Hold this stretch for 5 seconds
    • Press the affected finger and its neighbor close to each other
    • Repeat this 5 times

7. Finger Lifts

    • Place your palm on the table
    • Actively lift each finger off the table for 5 seconds
    • Repeat 5 times with more time on the injured finger
    • This increases the strength in the muscles of the fingers

8. Tendon Gliding

This is very necessary to avoid adhesions in the tendon as it heals. This form of exercise helps to relieve pain and reduce swelling.

    • Spread out your fingers wide
    • Bend your fingers towards the end of the palm except for the thumb
    • Take them back to their original position then bend them to the middle of the palm
    • Take each fingertip to the tip of the thumb
    • Take the tip of the thumb to the base of the fingers

Trigger Finger Symptoms

  1. Pain when bending and straightening the affected finger
  2. The stiffness of the fingers especially in the morning
  3. Locking and catching sensation

How Is It Treated?

1. See Your Doctor First

Seeing a doctor will help to pinpoint the major cause of the symptoms and if it is associated with other conditions. Sometimes, the doctor may advise running some diagnostic tests. Based on the results, the doctor will then manage the condition by prescribing medications and referring to a physiotherapist or a rheumatologist.

2. Analgesics

Medications with active ingredients like ibuprofen, naproxen, and diclofenac may be prescribed by the doctor to help relieve pain and reduce any form of swelling at the tendons. Topical gels with the same active ingredients may be recommended as well that can be used to massage the affected finger.

3. Rest

Resting from activities involving the finger will help to speed up healing to avoid further irritation of the already irritated tendon.

4. Ice

Ice is usually recommended to relieve pain and also to reduce swelling. Depending on the course of the injury, a physiotherapist may change this modality to heat modalities to reduce joint stiffness. Ice immersion, which involves placing the entire hand in a bowl of crushed ice and water, is usually advised for trigger finger. This should not be done for more than a few minutes.

5. Orthotics

A splint is recommended for a trigger finger to avoid unnecessary movement of the finger.

6. Physiotherapy

Physiotherapy’s main goal is to relieve pain, increase joint movement and prevent deformities that may arise from the condition. A physiotherapist will have gotten some information from the referring doctor and will carry out an assessment on the affected finger and other associated joints like the wrist.

After carrying out the assessment, the physiotherapist will:

  • Relieve pain using heating modalities like infrared, paraffin wax bath or ice. Using heating modalities can increase blood flow around the affected finger or the synovial fluid in the sheath to allow for easy movement of the tendon and the finger.
  • Massage can also be used to relieve pain. Frictional massage can help to reduce and prevent adhesions at the tendon while kneading massage can help reduce the swelling and improve range of motion.
  • Increase the range of movement at the joint by reducing joint stiffness. This can be done by using the heating modalities mentioned earlier and passively stretching the affected finger to the client’s limit.
  • Strengthening exercises to the hand and fingers. strong muscles support injured tendons and ligaments and help to relieve the pressure on the injured soft tissues as well. The physiotherapist will prescribe the exercises based on the assessment findings.
  • Modify a daily lifestyle. For instance, if your job expects a lot of typing, rets or stretch breaks can be suggested.

7. Steroid Injections

Unlike other pain medications that are basically non-steroidal, corticosteroids are stronger and faster pain-relieving medications. They are injected into the affected finger to reduce inflammation and swelling thereby relieving pain. However, they have side effects such as pain or discomfort for some days at the injection site and may also cause an infection at the painful joint.

8. Surgery

A trigger finger release surgery is done as a last resort if other forms of treatment do not alleviate the symptoms. The two major forms of surgery that are usually done are:

Open Surgery – In this type of surgery, the tendon sheath is cut to allow for easy movement of the tendon. This is done under local anesthesia given in the affected hand. A cut is done in the palm under the affected finger. The surgeon moves the affected finger while gradually cutting the tendon sheath until the movement is free.

Percutaneous Release – Unlike open surgery where there is an incision, percutaneous release involves injecting a needle into the sheath and moving it within the sheath and moving the finger at the same time to try and reduce any restriction the tendon may have in the sheath.

Complications

If a trigger finger is not well treated, it may lead to the finger being in a permanently bent or straightened position. This often requires surgery. However, complications may arise from performing surgery such as:

  • Infection
  • Tendon position might have been changed
  • Damage to blood vessels in the sheath
  • Nerve injury
  • Pain
  • Recurring palm swelling
