Carpal Tunnel Syndrome: Symptoms, Causes, and How Physiotherapy Can Help

Reviewed by the Physiotherapy Team at Waterloo Sports Medicine Centre 

Experiencing numbness, tingling, or pain in your hand, especially at night? You may be dealing with carpal tunnel syndrome (CTS), one of the most common nerve conditions affecting the wrist and hand. 

What Is Carpal Tunnel Syndrome? 

Carpal tunnel syndrome occurs when the median nerve, which travels from the forearm into the hand, becomes compressed as it passes through a narrow space in the wrist called the carpal tunnel.

Common symptoms include: 

• Numbness or tingling in the thumb, index, middle, and part of the ring finger 

• Hand pain that may radiate into the forearm 

• Symptoms that are often worse at night 

• Weakness or difficulty gripping objects 

• Frequent dropping of items or reduced hand dexterity

Without treatment, symptoms can gradually worsen and may affect everyday activities such as typing, driving, cooking, or sleeping. 

What Causes Carpal Tunnel Syndrome? 

In many cases, there is no single cause. Carpal tunnel syndrome often develops due to a combination of factors that increase pressure on the median nerve. 

Potential contributors include: 

• Repetitive hand or wrist movements 

• Prolonged gripping or use of vibrating tools 

• Wrist injuries or fractures 

• Pregnancy-related swelling 

• Diabetes 

• Thyroid disorders 

• Rheumatoid arthritis 

• Obesity and fluid retention

  
  

Who Is at Risk? 

You may be more likely to develop carpal tunnel syndrome if you: 

• Perform repetitive hand-intensive work 

• Spend long periods typing or using tools 

• Are female 

• Are pregnant 

• Have diabetes or arthritis 

• Have previously injured your wrist

How Can Physiotherapy Help? 

Physiotherapy is often an effective first-line treatment for mild to moderate carpal tunnel syndrome and can help reduce symptoms, improve hand function, and prevent progression. Your physiotherapist may recommend: 

Activity Modification and Education

Identifying movements or positions that aggravate symptoms and modifying daily activities to reduce stress on the median nerve. 

Wrist Splinting 

A neutral wrist splint, particularly at night, can help decrease pressure within the carpal tunnel and improve symptoms. 

Nerve and Tendon Gliding Exercises 

Specific exercises can improve the movement of the median nerve and surrounding tendons, helping reduce irritation and improve function. 

Manual Therapy 

Hands-on techniques for the wrist, forearm, and surrounding tissues may help improve mobility and reduce symptoms in some individuals. 

Strengthening and Ergonomic Advice 

As symptoms improve, strengthening exercises and workstation modifications can help prevent recurrence and support long-term recovery

Recovery and Healing Time 

Recovery varies depending on symptom severity and how long the condition has been present. 

Mild cases: Improvement may occur within 4-8 weeks with physiotherapy, activity modification, and splinting. 

Moderate cases: Recovery may take 2-3 months and sometimes requires additional medical treatment. 

Severe or long-standing cases: If there is significant nerve compression, persistent numbness, or muscle weakness, surgery may be recommended. Recovery following carpal tunnel release surgery often takes several weeks to a few months, depending on the individual.

Seeking treatment early generally leads to better outcomes and may reduce the risk of permanent nerve damage. 

When Should You See a Physiotherapist? 

Consider booking an assessment if you have: 

• Numbness or tingling that wakes you at night 

• Persistent hand or wrist pain 

• Difficulty gripping objects 

• Hand weakness or dropping items 

• Symptoms that interfere with work, sports, or daily activities
