Background and Need:- Trigger finger being one of
the common causes of pain and disability in the
hand, is thought to be caused by inflammation and
narrowing of the A1 pulley. Extracorporeal
Shockwave Therapy (ESWT) which is commonly
used to treat varied orthopaedic conditions, works
by correcting the mechanical insufficiency related to
trigger finger. This article aims to give an overview
of ESWT in reducing pain, stiffness and improving
range of motion in patients with trigger finger.
Methods:- 570 articles were retrieved from databases
viz. PubMed, Science Direct and Google Scholar.
Considering the inclusion and exclusion criteria, five
studies were found eligible for this review that
consisted of interventional and cohort studies.
Results:- Two randomised controlled trials found
significant reduction in pain intensity and severity of
triggering, but did not show any significant
differences in functional impact of triggering.
Alternately, two non-randomised trials and one
retrospective cohort study showed reduced pain
levels and increased general functional capacity,
grip strength, pinch strength and range of motion.
Conclusion:- ESWT can be consider as a safe and
effective treatment in alleviating pain and general
function in patients with trigger finger. However,
these findings need to be confirmed by future trials
and establish the short- and long-term effects of
ESWT on pain, range of motion, strength and
function in the management of trigger finger.
