Carpal tunnel syndrome (CTS) is a common condition of the wrist and hand that can affect the use of the whole arm. It is caused by pressure on the nerve at the base of the palm (median nerve).  Surgery for this condition is commonly performed on the wrist and hand. Fortunately for most people who develop CTS, physical therapy treatment like that offered at Progressive Physical Therapy can often relieve pain and numbness and restore normal use of the hand, wrist, and arm without the need for surgery.

What is carpal tunnel syndrome? 

About the width of your thumb, the carpal tunnel is a narrow channel on the palm side of your wrist. The tunnel protects the median nerve and the tendons that bend your fingers. Pressure on the nerve can cause pain and weakness in your wrist and hand and numbness or tingling in some of your fingers. This pressure is caused by crowding or irritation of the median nerve in the carpal tunnel and can lead to CTS.

Extreme wrist positions, as well as a lot of finger use, especially with a lot of force or vibration (such as holding the steering wheel when driving heavy machinery), can all contribute to CTS.

CTS is common in professions such as assembly-line work, particularly meat packing; and jobs requiring the use of hand tools, especially tools that vibrate. Although excessive keyboard and computer use is often associated with CTS, those performing assembly line work are 3 times more likely to develop CTS than those who perform data entry work. Some leisure activities can also create CTS, such as sewing, sports such as racquetball and handball, and playing string instruments such as the violin.

The following health conditions can also lead to CTS in some individuals:

  • Inflammation and swelling of the tendons of the wrist
  • Injuries to the wrist (strain, sprain, dislocation, fracture)
  • Hormone or metabolic changes (pregnancy, menopause, thyroid imbalance)
  • Fluid retention (eg, during pregnancy)
  • Diabetes
  • Certain medicine use (eg, steroids)
  • Degenerative and rheumatoid arthritis

How can a physical therapist help?

After the evaluation, your physical therapist at Progressive Physical Therapy will prescribe your treatment plan based on your specific case.

Conservative Care

If your evaluation confirms early-stage CTS, conservative care will be recommended as a first step. Physical therapy treatment can be effective in reducing your symptoms and getting you back to performing normal activities. During your first visit with the physical therapist, be prepared to describe your symptoms in as much detail as possible, and say what makes your symptoms worse.

Depending upon the causes of your CTS, your therapy program may include:

  • Education regarding:
    • changing wrist positions (ie, avoiding prolonged bent wrist positions)
    • proper neck and upper back posture (ie, avoiding forward head or slouching)
    • safe use of sharp utensils, tools, or other implements, if sensory changes are identified
    • “stretch breaks” during your work or daily routine
  • Exercises to increase the strength of the muscles in your hand, fingers, and forearm—and in some cases, the trunk and postural back muscles
  • Stretching exercises to improve the flexibility of the wrist, hand, and fingers
  • Use of heat/cold treatments to relieve pain
  • Use of a night splint to reduce discomfort
  • A worksite visit to assess your work area. For example, if you sit at a desk and work on a computer, it’s important for the keyboard to be in proper alignment to help avoid working in a bent wrist position.
  • Increasing the size of tool and utensil handles by adding extra material for a more comfortable grip
  • Anti-vibration gloves or anti-vibration wraps around tool handles, if vibration is a factor at your workplace

Your physical therapist will also consider your home and leisure activities, with recommendations such as wearing gloves to keep the wrist/hands warm and limiting sports that aggravate the condition, such as racquet sports, until symptoms resolve.

The goals of physical therapy are to reduce your symptoms without the need for surgery, to enable you to be as active and functional as possible, and to help you resume your normal work, home, and leisure activities.

Physical Therapy Following Surgery

If the evaluation reveals that your CTS is more severe, or if your symptoms persist, your physical therapist may refer you to a physician for a surgical consultation. If necessary, surgery will be performed to release the band of tissue that is causing pressure on the median nerve. Physical therapy treatment is important after surgery to help restore strength to the wrist and to learn to modify habits that may have led to symptoms in the first place. Your physical therapy treatment may include:

  • Exercises to improve the strength of the wrist/hand muscles and improve function
  • Stretching to improve mobility of the wrist/fingers and improve function
  • Scar management to keep the skin supple and flexible
  • Education regarding appropriate posture and wrist position to avoid carpal tunnel compression in home/leisure activities
  • A worksite visit or simulation to optimize postures and positions
