At Palms Physiotherapy & Allied Health, we specialise in diagnosing and treating Radial Tunnel Syndrome (RTS), a condition that involves compression of the radial nerve as it travels through the forearm. This condition can lead to pain, weakness, and numbness in the forearm and hand, impacting your daily activities. 

Our team of experienced physiotherapists, occupational therapists, and exercise physiologists work together to provide personalized, evidence-based treatment to alleviate symptoms and help you regain full function.

Symptoms of Radial Tunnel Syndrome

The symptoms of radial tunnel syndrome can vary from mild to severe and are often mistaken for other conditions, such as tennis elbow or carpal tunnel syndrome. Common symptoms include:

1. Pain in the Forearm

• Pain is often felt in the outer (lateral) forearm and may be described as a deep, aching or burning sensation.

• The pain typically worsens with repetitive arm movements, gripping, or wrist extension.

2. Tenderness Over the Radial Tunnel

• Tenderness is often noted in a specific area located just below the elbow, where the radial nerve passes through the radial tunnel.

3. Weakness

• Weakness or fatigue in the wrist and fingers may occur, making it difficult to extend the wrist or fingers properly.

4. Numbness or Tingling

• Numbness or a tingling sensation in the forearm or hand can occur, although sensory symptoms are less common than motor symptoms.

5. Pain that Worsens with Activity

• Pain may worsen with specific activities, such as gripping, lifting, or repetitive wrist and forearm movements (e.g., using a screwdriver, playing tennis, or lifting objects).

Causes of Radial Tunnel Syndrome

The radial nerve is susceptible to compression or irritation due to various factors that can lead to radial tunnel syndrome:

1. Repetitive Use or Overuse

• Repetitive activities that require gripping, wrist extension, or heavy lifting can contribute to swelling and irritation around the radial nerve. Professions or sports involving repetitive forearm movements, such as carpenters, tennis players, or athletes involved in racket sports, are at higher risk.

2. Trauma or Injury

• Direct injury to the elbow, forearm, or wrist can lead to swelling or scarring in the radial tunnel, which compresses the radial nerve.

3. Anatomical Abnormalities

• Some people may have anatomical differences, such as a tight or fibrous radial tunnel, that predispose them to nerve compression. In some cases, a benign growth, such as a cyst or bone spur, can also contribute to nerve compression.

4. Swelling from Inflammation

• Inflammation due to conditions such as tennis elbow (lateral epicondylitis) or other forearm injuries can lead to swelling that narrows the radial tunnel, putting pressure on the radial nerve.

Diagnosing Radial Tunnel Syndrome

Accurate diagnosis is essential to ensure proper treatment. Our team at Palms Physiotherapy & Allied Health uses a combination of physical examination, history-taking, and diagnostic testing to assess radial tunnel syndrome.

1. Physical Examination

• Palpation: Your physiotherapist will examine the forearm to assess for tenderness in the radial tunnel and check for muscle weakness or atrophy.

• Range of Motion: The physiotherapist may ask you to move your wrist and elbow in different directions to assess pain and restriction in movement.

• Nerve Tests: Specific tests (e.g., the resisted wrist extension test) can be performed to elicit symptoms and confirm the presence of radial nerve compression.

2. Imaging

While imaging is not always necessary, it can be helpful in certain cases:

• MRI: Magnetic resonance imaging can help identify any anatomical issues or structural abnormalities in the forearm, elbow, or wrist that may be contributing to compression.

• Ultrasound: Ultrasound can be used to assess for swelling or abnormalities in the radial tunnel.

3. Nerve Conduction Studies

In some cases, nerve conduction studies (NCS) or electromyography (EMG) may be performed to evaluate the function of the radial nerve and rule out other conditions.

Treatment for Radial Tunnel Syndrome at Palms Physiotherapy & Allied Health

The goal of treatment for radial tunnel syndrome is to reduce pressure on the radial nerve, relieve pain, and restore function. At Palms Physiotherapy & Allied Health, we offer a range of conservative treatments tailored to your individual needs:

1. Physiotherapy

Our physiotherapists are experts in providing non-invasive treatments to manage radial tunnel syndrome. We utilize a combination of:

• Manual Therapy: Hands-on techniques, such as soft tissue mobilization and joint mobilization, help reduce muscle tightness, improve blood flow, and decrease nerve compression.

• Stretching and Strengthening Exercises: Specific exercises are designed to stretch tight forearm muscles and strengthen weak muscles, promoting better muscle balance and reducing strain on the radial nerve.

• Nerve Mobilization: Gentle nerve gliding techniques can be used to improve the movement of the radial nerve and alleviate irritation.

• Activity Modification: Our physiotherapists will advise on ways to modify your daily activities to prevent further strain on the forearm muscles and radial nerve.

2. Splinting or Bracing

In some cases, a splint or brace may be recommended to support the wrist and reduce strain on the forearm. This is particularly useful during rest periods or at night.

3. Anti-inflammatory Medications

Non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, may be recommended to reduce pain and inflammation associated with radial tunnel syndrome. Corticosteroid injections may also be used in more severe cases to reduce inflammation and relieve symptoms.

4. Education and Ergonomics

We will educate you on how to adjust your posture, use ergonomic techniques, and incorporate proper wrist and arm positioning to prevent exacerbation of symptoms during daily activities.

5. Surgery (In Severe Cases)

In rare cases where conservative treatment is ineffective, surgical intervention may be considered to release the pressure on the radial nerve. Radial tunnel release surgery involves making an incision in the forearm to release the constricted tissue around the radial nerve.

Preventing Radial Tunnel Syndrome

While radial tunnel syndrome may not always be preventable, the following measures can help reduce the risk of developing the condition:

• Regular Stretching: Regularly stretching the forearm muscles can help prevent tightness and reduce the risk of compression on the radial nerve.

• Strengthening: Strengthening the forearm, wrist, and hand muscles helps maintain muscle balance and support proper nerve function.

• Gradual Increase in Activity: If you engage in activities that put strain on your forearm, it’s important to gradually increase intensity and take breaks to avoid overloading the muscles and nerves.

• Ergonomics: Implement proper ergonomics at work or while engaging in sports to avoid repetitive strain injuries.
