RSI

Repetitive Strain Injuries also known as Cumulative Trauma Disorders (CTD)s can occur in many parts of the body including wrist, elbow, back, neck, hip, knees and ankles.

Carpal Tunnel Syndrome (CTS)

Carpal Tunnel Syndrome is a form of RSI affecting the hand and wrist. It occurs when the nerves and tendons become irritated and swell. This occurs when there is added pressure on the nerve as it runs into the wrist through a passage called the carpal tunnel. The bottom of the tunnel is made up of the bones of the wrist and the top of the tunnel is made up of the carpal ligaments. The nerves and tendons run through this tunnel to the hand.

Causes

Flexor tendons rub against the walls of the carpal tunnel when you flex your hand or finger. In most cases if your hand is allowed time to recover this rubbing will not lead to irritation. The recovery time can vary from person to person.

CTS has a variety of causes and is often a result of a combination of factors. Among these factors are injuries and trauma (such as a blow to the wrist or lower arm), genetic predisposition, over flexion and over extension of the wrist as well as repetitive motion and vibration.

Symptoms

Symptoms can originate when hands and wrists are not given time to recover from flexing. Because of this delay in the onset of symptoms, many Carpal Tunnel Syndrome sufferers don't realize their work activities are causing the pain. The tingling can lead, over time, to stiffness and numbness in the fingers and hand, and then to severe wrist and hand pain.

  • Sensory motor numbness and loss of hand strength
  • At first, there may be numbness and tingling of the fingers or a burning feeling in the hand
  • Shooting pain in the wrist or forearm may follow and can move up the arm and to the back of the shoulder
  • Tingling and weakness on the thumb area
  • Burning sensation
  • Reduced muscle development
  • Coldness
  • Difficulty holding or pinching items
  • Pain often begins several hours after the work activity has stopped so it's usually worse at night

Prevention

  • Modifying or adjusting a workstation can help prevent CTS as well as changing the length of time spent on a computer or any other activity that aggravates the wrist
  • During the day an IMPACTO Wrist Support will help increase circulation, prevent over flexion and over extension and still allow flexibility while working
  • The IMPACTO Carpal Control has proven to provide relief for carpal tunnel syndrome sufferers
