Physical Therapist, Allyce Staffen, shares on Carpal Tunnel Syndrome- Symptoms, Risk Factors, Treatment, and Preventation.

Carpal Tunnel Syndrome – Anatomy
The carpal tunnel is a small tunnel found at the base of the palm of the hand. It is bordered by the little wrist bones and a thick ligament called the retinaculum. Inside this space, there is the median nerve and the tendons that bend the fingers and the thumb. The tendons are protected by a synovium sheath. When these get inflamed, this may put pressure on the median nerve.
What are the symptoms of Carpal Tunnel Syndrome?
Usually pain begins in the wrist and palm area, and at times the pain can be felt in the fingers and forearm. Tingling and numbness may occur along the median sensory distribution, which includes the thumb, index, middle, and half of the ring finger. In addition, progressive Carpal Tunnel Syndrome can result in motor weakness of the intrinsic muscles of the hand.
Other common symptoms include:
- Awakening at night by pain, cramping and/or numbness in the wrist and hand.

- Dropping objects, clumsiness.
- Having difficulty with gripping or pinching objects because of pain or weakness.
- Pain with writing or performing activities that require fine handling of objects like sewing, knitting or cutting.
- Pain to wrist or hand, and/or tingling and numbness to the fingers when gripping the wheel while driving.
- Pain to the anterior aspect of the shoulder.
Causes and Risk Factors:
Median nerve neuropathy, occurs when there is a compression on the median nerve, or a traction injury of the median nerve.
- Compression of the median nerve can happen when there is swelling surrounding the median nerve. Prolonged inflammation can also eventually lead to scar tissue surrounding the nerve.
- Traction of the median nerve can occur from an overstretching injury to the nerve such as a fall on the outstretched hand.
Most common activities and factors that increase the risks of developing carpal tunnel:
The most common risk factors to developing carpal tunnel are:
- Women: are more susceptible to developing carpal tunnel versus men. It is thought to possibly due to the carpal tunnel being smaller.
- Being overweight: Being overweight is well documented as a significant risk factor to developing carpal tunnel syndrome.
- Aging
- Sustained and, or forceful repetitive gripping: Manual workers in cold environment are particularly at risk ex: meat packers
- Fall on an outstretched hand
- Distal radius fracture
- Repetitive forceful or sustained gripping with vibration: ex: Manual workers using tools like jack hammers.
- Pregnancy: The increase in fluid retention is thought to be the reason of increased susceptibility to carpal tunnel syndrome while a women is pregnant. CTS will usually resolve following the birth.
- Diabetes
- Hypothyroidism
- Rheumatoid arthritis
- Tumors or ganglions
- Alcoholism
Acute Carpal Tunnel Syndrome Treatment and Prevention:
Early diagnosis and treatment is very important, therefore seeing your physician and hand therapist upon onset of symptoms will improve your outcome.
Important acute treatment considerations:
- Resting your wrist and hand is very important. A wrist splint that maintains your wrist straight should be worn daytime and nighttime during the acute phase. It has been shown in research that the pressure in the carpal tunnel is less when the wrist is kept in a neutral position. Wearing the wrist splint at night is very important to maintain this position. Most people tend to maintain their wrist in a bent position for prolonged periods at night. This position increases the pressure on the median nerve, therefore brings on tingling, numbness and/or pain during the night.
- You may apply an ice pack for 15 minutes to the wrist area for pain and swelling relief.
- NSAIDs (Nonsteriodal anti-inflammatory drugs).
- Physical Therapy for home exercise program guidance.
Activities to avoid any aggravating activities such as:
- Forceful or sustained gripping, carrying of lifting.
- Sustained use of the computer or mouse.
Prevention:
- Keep your hands warm. Your hands are more likely to get stiff and numb in cold weather.
- Take stretch breaks at work. Alternate tasks if possible to keep your hands from fatiguing.
- If you work at a desk, make sure to set up a proper work station and use ergonomic tools when possible ie large grip for mouse, oversized pens.
- If using tools that have a high frequency vibration, use vibratory dampening equipment ie. Anti-vibration gloves.
- As always, work on improving your posture!
