Carpal Tunnel Syndrome

Carpal tunnel syndrome is a common condition caused by compression of the median nerve as it passes through the wrist. It can cause numbness, tingling, discomfort and weakness in the hand and fingers and may interfere with work, exercise, sleep and everyday activities. 

Dr. Michael Hoiles has prepared this page as a resource to help you understand carpal tunnel syndrome, common symptoms, treatment options and when further assessment may be appropriate. 

​

 

Quick Facts 

✔ Carpal tunnel syndrome involves compression of the median nerve at the wrist. 

✔ Numbness and tingling commonly affect the thumb, index and middle fingers. 

✔ Symptoms are often worse at night. 

✔ Repetitive or sustained hand and wrist activities can aggravate symptoms. 

✔ Mild to moderate cases may respond to conservative management. 

✔ Persistent weakness or loss of hand function should be properly assessed.

Anatomy 

The carpal tunnel is a narrow passageway at the wrist formed by the wrist bones and a strong band of connective tissue called the transverse carpal ligament. 

The median nerve and several tendons travel through this space into the hand. When pressure within the tunnel increases, the median nerve can become compressed and produce symptoms in the hand and fingers. 

Carpal tunnel syndrome is one possible cause of hand and wrist pain, although many other muscles, tendons, joints and nerves can produce symptoms in this area.

​

 

What Is Carpal Tunnel Syndrome? 

Carpal tunnel syndrome occurs when the median nerve becomes compressed as it travels through the carpal tunnel at the wrist. 

The median nerve provides sensation to much of the thumb, index finger, middle finger and part of the ring finger. It also helps control several muscles involved in thumb movement. 

Symptoms can range from occasional tingling to persistent numbness, weakness and difficulty using the hand. 

​

 

Common Causes and Risk Factors

  • Repetitive hand or wrist activity 

  • Prolonged or repeated wrist positions 

  • Work involving gripping or vibrating tools 

  • Previous wrist injury 

  • Pregnancy and fluid retention 

  • Arthritis or changes around the wrist 

  • Certain medical conditions 

  • Individual anatomy of the carpal tunnel 

Sometimes there is no single identifiable cause. 

​

 

Common Symptoms 

  • Numbness or tingling in the hand 

  • Symptoms affecting the thumb, index and middle fingers 

  • Symptoms that are worse at night 

  • Waking with a numb or tingling hand 

  • Hand or wrist discomfort 

  • Reduced grip strength 

  • Dropping objects 

  • Difficulty with fine hand movements 

Symptoms can sometimes extend into the forearm. 

​

 

What Makes Carpal Tunnel Syndrome Worse? 

Symptoms may be aggravated by: 

  • Prolonged wrist bending 

  • Repetitive gripping 

  • Extended computer or keyboard use 

  • Holding a phone or steering wheel 

  • Repetitive hand-intensive work 

  • Vibrating tools 

  • Activities that repeatedly load the wrist 

Identifying and modifying aggravating activities can be an important part of conservative management. 

​

 

What Helps? 

Many people improve with: 

  • Relative rest and activity modification  

  • Gradual return to activity  

  • Strengthening exercises  

  • Mobility exercises  

  • Improving workstation ergonomics  

  • Improving lifting technique  

  • Temporary bracing when appropriate  

  • Manual therapy  

  • Managing training loads  

  • Addressing contributing shoulder and forearm strength deficits  

Treating the entire kinetic chain—not just the painful wrist—often leads to better long-term outcomes. 

​

 

Could My Symptoms Be Coming From Somewhere Else? 

Yes. Not every numb or tingling hand is caused by carpal tunnel syndrome. 

Similar symptoms can sometimes originate from the neck, forearm or another location along the nerve pathway. Other nerve conditions can also produce hand symptoms. 

Determining where the nerve is being irritated is an important part of choosing the appropriate treatment. 

​

 

How Is Carpal Tunnel Syndrome Diagnosed? 

Diagnosis typically involves reviewing your symptoms and examining the hand, wrist and arm. 

Assessment may include sensation, grip strength, thumb strength and tests that place stress on the median nerve. The neck, shoulder and forearm may also be assessed because symptoms from other areas can sometimes resemble carpal tunnel syndrome. 

When the diagnosis is uncertain or symptoms are significant, nerve conduction studies or other medical investigations may be recommended. 

​

 

How Chiropractic Can Help 

For appropriate mild to moderate cases, chiropractic management may focus on improving function and addressing factors contributing to symptoms. 

Depending on the assessment, treatment may include: 

  • Wrist and forearm manual therapy 

  • Soft tissue treatment 

  • Activity and ergonomic modifications 

  • Nerve mobility exercises when appropriate 

  • Hand, wrist and forearm rehabilitation 

  • Assessment of the neck and upper extremity 

If symptoms suggest significant nerve compression or aren't responding appropriately, further medical investigation or referral may be recommended. 

​

 

Recovery varies considerably depending on the severity and duration of nerve compression. 

  • Mild cases: symptoms may improve over several weeks with appropriate activity changes and conservative care. 

  • Moderate cases: may require several weeks or months of management. 

  • More advanced cases: particularly those involving persistent numbness, weakness or muscle loss, may require medical or surgical treatment. 

Earlier assessment is particularly important when weakness or loss of function is developing. 

​

 

Exercises Commonly Recommended 

Exercise depends on the individual presentation, but may include: 

Phase 1 – Reduce Irritation 

  • Gentle wrist mobility 

  • Median nerve mobility exercises 

  • Finger and hand movement 

  • Postural and activity modifications 

Phase 2 – Restore Function 

  • Grip exercises 

  • Wrist strengthening 

  • Forearm strengthening 

  • Progressive nerve mobility when appropriate 

Phase 3 – Return to Activity 

  • Progressive gripping 

  • Functional wrist strengthening 

  • Work-specific exercises 

  • Gym- or sport-specific loading 

Exercises should not repeatedly provoke significant numbness or tingling. 

​

Can I Still Exercise? 

Usually, yes. 

Exercises that place prolonged pressure on the wrist or significantly increase numbness and tingling may need to be modified temporarily. 

Training can often continue by adjusting wrist position, grip, load or exercise selection while symptoms are being addressed. 

​

 

When To Seek An Assessment 

Consider an assessment if: 

  • Numbness or tingling keeps returning 

  • Symptoms frequently wake you at night 

  • Symptoms interfere with work or exercise 

  • Grip strength is decreasing 

  • You frequently drop objects 

  • Symptoms aren't improving with simple activity changes 

​

Common Mistakes That Slow Recovery 

  • Ignoring persistent numbness 

  • Repeatedly aggravating symptoms 

  • Sleeping with the wrist significantly bent 

  • Assuming every tingling hand is carpal tunnel syndrome 

  • Continuing the same workload without modification 

  • Waiting too long to assess progressive weakness 

​

 

When Should I worry?  

Seek medical assessment if you develop progressive hand weakness, persistent loss of sensation, noticeable muscle wasting around the thumb or rapidly worsening symptoms. 

Significant or progressive nerve compression should not simply be treated as a sore wrist. 

​

 

Frequently Asked Questions 

Which fingers are affected by carpal tunnel syndrome? 
Symptoms most commonly affect the thumb, index finger, middle finger and part of the ring finger. 

 

Why is carpal tunnel often worse at night? 
Wrist position during sleep and changes in pressure within the carpal tunnel can contribute to nighttime symptoms. 

 

Does a wrist brace help? 
A neutral-position wrist splint, particularly at night, can help some people with mild to moderate symptoms. 

 

Can carpal tunnel syndrome come from my neck? 
True carpal tunnel syndrome involves compression at the wrist, but nerve irritation originating from the neck can sometimes produce similar hand symptoms. 

 

Can I still work out? 
Usually. Exercises may need to be modified if certain wrist positions or gripping activities increase numbness and tingling. 

 

Does carpal tunnel syndrome always require surgery? 
No. Mild to moderate cases may respond to conservative treatment, while more severe or persistent nerve compression may require surgical assessment.
