What is Laser Therapy?

Low-level laser therapy (LLLT) is a type of phototherapy that is also called cold laser or soft laser therapy. It is a non-invasive
technique that focuses low-level or low-intensity laser infrared light beams on the injured tendon. Low-level laser therapy for
tendinitis differs dramatically from conventional laser surgery that uses hot or high-intensity laser beams to treat cancer or other
medical conditions.

Laser therapy for tendinitis is painless. The patient may feel a warm, tingling sensation as the nerves are stimulated. Laser
surgery for tendinitis requires at least ten treatments, usually of short duration.

Laser acupuncture is also used to treat tendinitis. With laser acupuncture, the laser beam is focused on the appropriate
acupuncture points, eliminating the need for needles. Although there is evidence that acupuncture can be an effective treatment
for tendinitis, the evidence for the effectiveness of laser acupuncture is less compelling.


Is Laser Therapy Safe for Carpal Tunnel?

LLLT is considered to be safe and has no known side effects. However, the laser beam should never be:
  • Shone directly into an eye
  • Used on the abdomen of a pregnant woman
  • Used in the presence of photosensitive compounds
  • Applied directly to cancerous tissue

What is Carpal Tunnel syndrome (CTS)?

Carpal Tunnel Syndrome is a painful and disabling disorder
characterized by inflammation and swelling of the tendons that
run through the narrow carpal tunnel in the wrist, and is one of
the most common of repetitive stress injuries. Numbness,
tingling, and pain in the base of the thumb and the first three
fingers results from the compression of a nerve that shares the
carpal tunnel. The syndrome, categorized by the World Health
Organization as a work-related musculoskeletal disorder, is
caused by excessive and unrelieved repetition of movements that
in themselves appear innocuous, such as cutting meat or typing
on a computer keyboard. In addition to high frequency of
repetition and lack of rest periods, factors that increase risk of
hand-wrist damage include awkward or unnatural working
posture, use of excessive force in performing a task, and
emotional stress. 70% of all manual wheel chair users will suffer
from this condition.

Conventional CTS treatments include simple hand splinting;
steroid injection into the carpel tunnel, which has marginal
long-term efficacy; and, surgical release of the impinging
ligament.

More than half of all workers afflicted with CTS miss over 30 days
of work. Clearly, these statistics warrant the consideration of less
expensive, less invasive, and more effective therapeutic
alternatives for CTS, Such as Laser Therapy.

How Does Laser Therapy Treat Carpal Tunnel?

Laser treatments can work effectively for carpal tunnel syndrom. In Cold laser treatment, Microlight is the device that delivers a
"cold" laser beam deep into the tissue of the wrist and forearm to stimulate cell growth and reduce the swelling that's
characteristic of carpal tunnel syndrome .
.
Wrist splints and anti-inflammatories help some people, but surgery to cut the ligament sometimes is necessary. Laser therapy
provides another treatment. The device is held against the skin and delivers about 30 seconds of laser light at a time before
being moved to a new area.

Unlike surgical lasers, Cold lasers used in this procedure don't produce heat so it doesn't destroy the  tissue. The cold laser
uses a different wavelength of light, so it is able to penetrate deep into tissue with no pain involved.
