Stopping the
Effects of Trigger Thumb
Trigger thumb is a common repetitive strain injury that
can cause significant impairment in hand strength, dexterity,
and daily functioning. The condition is characterized
by pain and catching in the thumb, and it can result
in difficulty performing everyday tasks. Although there
are many organic causes of trigger thumb, environmental
factors (e.g., workplace conditions and job demands)
usually play a significant role.
Trigger thumb (or tenosynovitis, as it is also known)
is the result of a degenerative process in the tendon
that runs through the thumb. Specifically, the flexor
pollicis longus tendon deteriorates, which in turn leads
to swelling in the tendon. This inflammation and irritation
impedes the movement of the tendon at the metacarpophalangeal
joint. Essentially, the tendon in the thumb gets trapped
which produces the painful catching or clicking that
is commonly associated with trigger thumb.
The condition is more common in women than men, and
it is more likely in people suffering from other chronic
illnesses. Rheumatoid arthritis and diabetes, for example,
are common correlates of trigger thumb. However, movement
also play a role in the manifestation of the malady.
Repetitive strain on the hands through heavy lifting,
typing, and long hours at a steering wheel can lead to
trigger finger as well.
There are numerous treatment options for reducing pain
and impairment associated with triggering. Often rest and
over-the-counter medications are enough to bring temporary
relief. Individuals looking for long-term treatment for
trigger thumb, however, are advised to consider exercises
that promote the integrity of the muscles and tendons in
the hand and forearm such as those offered by FLEXTEND® and
the RESTORE™ products.
