Trigger Finger Physiotherapy Rehabilitation

Trigger Finger Physiotherapy

Trigger finger, scientifically known as stenosing tenosynovitis, is a condition characterized by the involuntary locking or catching of a finger in a bent position.

It’s a condition that affects the flexibility and smooth movement of the fingers and can be a source of discomfort and pain.

Whether you’re an athlete, an office worker, or anyone in between, understanding the trigger finger physiotherapy rehabilitation is essential.

The root cause often lies within the tendons and their protective sheaths in the hand, particularly the flexor tendons responsible for finger movement.

The narrowing of these sheaths due to inflammation or thickening leads to the triggering sensation, impeding smooth finger movement.

Causes Of Trigger Finger

Understanding the causes behind this condition is essential for both prevention and effective treatment.

Repetitive Hand Movements:

Engaging in repetitive hand movements, especially those involving forceful gripping or grasping, can lead to the development of a trigger finger.

Activities such as using tools, playing musical instruments, or even typing for extended periods can strain the finger tendons, leading to inflammation and subsequent constriction.

Occupational Hazards:

Certain occupations, such as repetitive hand tasks or heavy manual labor, can increase the risk of trigger fingers.

People working in construction, manufacturing, and assembly lines are particularly susceptible due to the constant strain on their hand tendons.

Medical Conditions:

Underlying medical conditions, including diabetes and rheumatoid arthritis, have been linked to an increased risk of trigger finger.

These conditions can cause changes in the tendon structure and metabolism, making the tendons more prone to inflammation and thickening.

Gender and Age:

Women and individuals over the age of 40 are more likely to experience trigger fingers.

Hormonal changes and age-related degeneration of tendons can contribute to the development of the condition.

Overuse and Strain:

Overexertion of the finger tendons due to excessive hand use or sudden increase in activity can lead to a trigger finger.

This overuse causes inflammation and swelling in the tendon sheath, impairing the smooth gliding of the tendons.

Anatomical Factors:

Certain anatomical factors, such as the shape and size of the finger tendons, can make some individuals more susceptible to trigger fingers.

People with naturally thicker tendons or narrower sheaths may experience more friction and constriction, leading to the condition.

Trauma or Injury:

Direct trauma to the hand or finger, such as a sprain or fracture, can disrupt the normal alignment of the tendons and their sheaths.

This disruption can lead to inflammation and trigger finger symptoms.

Signs and Symptoms of Trigger Finger

The most common signs and symptoms of trigger finger include:

  • Finger Catching or Locking: The most distinctive symptom of the trigger finger is the sensation that the affected finger(s) catch, lock, or get stuck in a bent position. This occurs due to the narrowing of the tendon sheath, making finger movement difficult.
  • Pain and Discomfort: Pain and discomfort are commonly experienced at the base of the affected finger or thumb. The pain can range from mild to severe and may worsen with movement or pressure.
  • Tenderness and Swelling: Tenderness around the affected finger’s base, accompanied by localized swelling, can be observed. The area may feel tender to the touch due to inflammation.
  • Clicking Sensation: As the finger is straightened, a noticeable clicking or snapping sensation might occur. This clicking sound is the result of the tendon suddenly moving through the narrowed sheath.
  • Stiffness and Limited Range of Motion: Individuals with trigger fingers often experience stiffness in the affected finger, making it challenging to fully extend or flex the finger. The range of motion becomes limited due to the tendon’s restricted movement.
  • Morning Stiffness: Many people, notice increased stiffness and discomfort in the morning, which tends to improve as the day progresses and the finger becomes more active.
  • Difficulty Grasping Objects: A trigger finger can make it difficult to grip objects firmly, as the finger’s ability to fully close or open is compromised.
  • Visible Finger Deformity: In severe cases, prolonged untreated trigger fingers can lead to the affected finger appearing slightly bent or crooked, indicating significant tendon thickening and constriction.
  • Aggravation with Activities: Activities that involve repetitive gripping or grasping, such as holding a pen or using tools, can exacerbate the symptoms of a trigger finger.
  • Multiple Finger Involvement: While the trigger finger commonly affects a single finger, it can also occur in multiple fingers or both hands simultaneously.

Trigger Finger Physiotherapy Rehabilitation

A physiotherapy treatment protocol for the trigger finger aims to alleviate symptoms, improve finger function, and prevent recurrence.

This comprehensive approach involves a combination of exercises, manual therapy, and education.

It’s important to note that the protocol can vary based on the severity of the condition and the individual’s specific needs. Always consult a qualified physiotherapist for personalized guidance.

Below is a generalized physiotherapy treatment protocol for trigger finger:

Phase 1: Initial Assessment and Education

Initial Evaluation:

The physiotherapist assesses the individual’s medical history, symptoms, and finger mobility to determine the severity of the trigger finger.


The patient is educated about the trigger finger, its causes, and the importance of adhering to the treatment plan. Ergonomic advice and recommendations for activity modifications are provided.

Phase 2: Reduction of Inflammation and Pain Management


Modalities such as ice therapy or ultrasound may be used to reduce inflammation and alleviate pain in the affected finger.

Manual Therapy:

Gentle joint mobilizations and soft tissue techniques are performed by the physiotherapist to improve blood circulation and relieve finger stiffness.

Phase 3: Range of Motion and Flexibility Exercises

Finger Stretches:

The patient is guided through gentle finger stretches to improve flexibility and reduce stiffness in the affected finger’s joints.

Tendon Gliding Exercises:

Specific exercises involving controlled finger movements are introduced to promote the smooth gliding of the tendon within its sheath.

Phase 4: Strengthening Exercises

Finger Abduction/Adduction:

Exercises that involve spreading the fingers apart and then bringing them back together help strengthen the muscles responsible for finger movement.

Grip Strengthening:

The patient performs grip-strengthening exercises using resistance bands, stress balls, or other specialized tools to enhance finger strength.

Phase 5: Gradual Progression and Monitoring

Progressive Exercises:

The physiotherapist gradually increases the intensity of exercises as the patient’s symptoms improve, ensuring that the affected finger’s mobility and strength continue to improve.

Monitoring and Adjustments:

Regular follow-up appointments are scheduled to monitor progress and make necessary adjustments to the treatment plan based on the patient’s response to therapy.

Phase 6: Ergonomic Advice and Prevention Strategies

Ergonomic Guidance:

The physiotherapist provides advice on proper hand posture, ergonomics, and techniques to minimize the risk of trigger finger recurrence.

Activity Modifications:

Patients are educated about the importance of varying hand activities, taking breaks during repetitive tasks, and avoiding activities that may strain the affected finger.

Phase 7: Long-Term Maintenance

Home Exercise Program:

The patient is provided with a personalized home exercise program that includes a combination of stretching, tendon gliding, and strengthening exercises.


Patients are encouraged to continue practicing the exercises and ergonomic strategies learned during physiotherapy sessions to maintain finger flexibility and strength.

Phase 8: Follow-Up and Discharge

Discharge Planning:

Once the patient achieves optimal finger function and experiences reduced symptoms, they are discharged from regular physiotherapy sessions.


Periodic follow-up appointments may be recommended to ensure that the patient’s progress is sustained and to address any new concerns.


This physiotherapy treatment protocol is designed to provide comprehensive care for the trigger finger, addressing pain, improving finger function, and minimizing the risk of recurrence. However, individual variations in treatment plans may occur based on factors such as the severity of the condition, patient compliance, and response to therapy. It’s crucial to consult a skilled physiotherapist for personalized assessment and guidance.
