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
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. Take a moment
