Carpal Tunnel Syndrome: Causes, Symptoms and Treatment.


Carpal tunnel syndrome is a disorder that affects the hands and wrists, which can be quite painful. The carpal tunnel is a passageway at the base of the hands or the wrists, made up of bones and ligaments, through which the median nerve passes. – PowerPoint PPT presentation

Title: Carpal Tunnel Syndrome: Causes, Symptoms and Treatment.

Causes Symptoms Treatment Preventions
  • Carpel Tunnel Syndrome

Introduction to Carpel Tunnel Syndrome
  • Carpal tunnel syndrome is a common condition
    that causes pain, numbness, and tingling in the
    hand and arm. The condition occurs when one of
    the major nerves to the hand the median nerve
    is squeezed or compressed as it travels through
    the wrist.
  • Tingling, Numbness and pain in your first three
    fingers and thumb of your hand are common
    symptoms of carpal tunnel syndrome.
  • The pain in your carpal tunnel is due to excess
    pressure in your wrist and on the median nerve. 
  • Carpal tunnel syndrome can be made worse if the
    wrist is overextended repeatedly.

Causes of Carpel Tunnel Syndrome
  • Women are actually 3 times more likely to have
    symptoms of carpal tunnel syndrome.
  • Most often a result of a person's occupation.
  • Activities requiring continual use of the hands.
  • Repetitive motions using force.
  • Prolonged flexion or extension of the wrist.
  • gripping.
  • Pressure over the palm.
  • Trauma.
  • Fractures.
  • Vibration.
  • Examples data-entry, meat cutters, assembly,
    construction workers, and musicians.

Symptoms of Carpel Tunnel Syndrome
  • Tingling or numbness in the fingers and hands,
    particularly the thumb, the index finger, and the
    middle finger.
  • Pain in the forearm, palm, or wrist.
  • Increased numbness felt during the night compared
    to the day time. In fact, the pain could be so
    intense, that it could wake you up. You may find
    yourself rubbing or shaking your hand in order to
    alleviate the pain.
  • Increased pain on using the wrist or hand more.
  • Weakness in the thumb.
  • Difficulty in gripping things.

Diagnosis of Carpel Tunnel Syndrome
  • Physical examination. Your doctor will conduct a
    physical examination. He or she will test the
    feeling in your fingers and the strength of the
    muscles in your hand.
  • X-ray. Some doctors recommend an X-ray of the
    affected wrist to exclude other causes of wrist
    pain, such as arthritis or a fracture.
  • Electromyogram. Electromyography measures the
    tiny electrical discharges produced in muscles.
    During this test, your doctor inserts a
    thin-needle electrode into specific muscles. The
    test evaluates the electrical activity of your
  • Nerve conduction study. In a variation of
    electromyography, two electrodes are taped to
    your skin. A small shock is passed through the
    median nerve to see if electrical impulses are
    slowed in the carpal tunnel. This test may be
    used to diagnose your condition and rule out
    other conditions.

Treatments of Carpel Tunnel Syndrome
  • Home treatment, such as changing or avoiding
    activities that may be causing symptoms and
    wearing a wrist splint.
  • Physical therapy or occupational therapy. This
    includes ultrasound, stretching, and
    range-of-motion exercises.
  • Medicines, such as nonsteroidal anti-inflammatory
    drugs (NSAIDs) to relieve pain and reduce
    inflammation. In some cases, oral corticosteroids
    or corticosteroid injections into the carpal
    tunnel may be considered.
  • Surgery. Surgery is sometimes recommended when
    other treatment hasn't helped, if you've had
    carpal tunnel syndrome for a long time, or if
    there is nerve damage or the risk of nerve

Preventions of Carpel Tunnel Syndrome
  • If your job requires performing the same tasks
    over and over with your hands, try not bending,
    twisting or extending your hands for extended
    periods of time.
  • Avoid resting your wrists on surfaces that are
    hard for extended periods of time.
  • While working, see that your arms are not too far
    away or too close to your body.
  • While performing tasks, keep switching hands.
  • Taking breaks regularly from repetitive hand
    movements is a good way to give your wrists and
    hands time to rest.
  • Ensure that the tools you are using are not too
    large for your hands.
  • If you use the keyboard for extended periods of
    time, make sure to see that your forearms are at
    the same level as the keyboard, and that you do
    not need to flex your wrists in order to type.
