Wrist flexor injuries are prevalent, particularly among individuals engaged in repetitive activities or sports that strain the wrist and forearm muscles

Understanding the symptoms and treatments for these injuries is crucial for effective management and rehabilitation. In this blog, we'll explore the most common wrist flexor injuries, their symptoms, typical treatments, and the role of trigger points in exacerbating these conditions.

Anatomy of the Wrist Flexors:
Before diving into specific injuries, let's briefly review the anatomy of the wrist flexors. The wrist flexors are a group of muscles located on the anterior aspect of the forearm. The primary wrist flexors include the flexor carpi radialis, flexor carpi ulnaris, and palmaris longus. These muscles play a vital role in flexing the wrist and fingers and are heavily involved in various activities such as typing, gripping, and lifting.

Common Wrist Flexor Injuries:
1. Tendinitis/Tendinosis: Tendinitis, or its chronic counterpart tendinosis, occurs when the tendons of the wrist flexors become inflamed or damaged due to overuse or repetitive strain. Symptoms include pain, swelling, and tenderness along the front of the wrist or forearm. Activities such as typing, gripping tools, or playing racquet sports can exacerbate these symptoms.

2. Flexor Carpi Radialis Strain: This injury involves overstretching or tearing of the flexor carpi radialis muscle or its tendon. It typically occurs due to sudden forceful movements or repetitive stress. Symptoms include pain and weakness in the wrist, particularly during wrist flexion and radial deviation (moving the wrist towards the thumb).

3. Carpal Tunnel Syndrome (CTS): While not solely a wrist flexor injury, CTS can involve compression of the median nerve as it passes through the carpal tunnel, which is surrounded by wrist flexor tendons. Repetitive motions, such as typing or assembly line work, can contribute to the development of CTS. Symptoms include numbness, tingling, and weakness in the thumb, index, middle fingers, and half of the ring finger.

Symptoms and Trigger Points:
Trigger points, or localized areas of muscle tension, can contribute to wrist flexor injuries by causing referred pain and limiting range of motion. Common trigger points associated with wrist flexor injuries include those in the flexor carpi radialis and flexor carpi ulnaris muscles. Referred pain from trigger points may mimic symptoms of tendinitis or strain and can exacerbate existing conditions.

Typical Treatments:
1. Rest and Immobilization: Resting the affected wrist and avoiding activities that exacerbate symptoms is essential for recovery. Immobilization through splinting or bracing may be recommended to reduce stress on the injured wrist flexors.

2. Ice Therapy: Applying ice packs to the affected area can help reduce pain and inflammation. Ice therapy can be particularly beneficial after activities that aggravate symptoms.

3. Stretching and Strengthening Exercises: Gradual introduction of stretching and strengthening exercises can promote flexibility and resilience in the wrist flexor muscles. Physical therapy or guided exercise programs may be recommended for optimal results.

4. Trigger Point Therapy: Addressing trigger points through massage, trigger point release techniques, or dry needling can help alleviate referred pain and improve muscle function in the wrist flexors.

5. Anti-inflammatory Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) may be prescribed to reduce pain and inflammation associated with wrist flexor injuries. However, prolonged or excessive use should be avoided due to potential side effects.

Understanding the symptoms and treatments for common wrist flexor injuries is essential for effective management and rehabilitation. By incorporating rest, ice therapy, stretching, strengthening exercises, and targeted trigger point therapy into a comprehensive treatment plan, individuals can alleviate pain, restore function, and prevent recurrent injuries. If you suspect a wrist flexor injury, consult with a healthcare professional for an accurate diagnosis and personalized treatment recommendations.

Remember, proactive care and proper ergonomics can help mitigate the risk of wrist flexor injuries, ensuring continued comfort and functionality in daily activities and sports.


Wrist Flexors 



Trigger points build up over time, and may be the precursor to more complex injuries when left untreated. Simple daily stretching may help to prevent the activation of latent trigger points.

Here's a simple stretch that we often recommend. Start by allocating just a minute each day to this stretch.

Try to perform the stretch at least once a day, at the end of a long drive, or perhaps when you get up to take a break from your desk.

Build up from there but, as always, don't push too hard or over-stretch.

If you happen to be a manual therapists, you should be performing this stretch in between each client!



Stretching for Trigger Points




Hold onto your fingers and turn your palms outwards. Straighten your arm and then pull your fingers back using your other hand.


Primary muscles: Brachialis. Brachioradialis. Pronator teres. Flexor carpi radialis. Flexor carpi ulnaris. Palmaris longus.

Secondary muscles: Flexor digitorum superficialis. Flexor digitorum profundus. Flexor pollicis longus.


Tennis elbow. Golfer’s elbow. Thrower’s elbow. Wrist sprain. Wrist dislocation. Wrist tendonitis. Carpal tunnel syndrome. Ulnar tunnel syndrome.


The forearms, wrists, and fingers comprise a multitude of small muscles, tendons, and ligaments. Do not overstretch this area by applying too much force too quickly.
