Myofascial trigger points (MTrPs) are involved in pain
associated with autonomic nervous systems caused by one
or several hyperirritable spots called trigger points (TrPs)
in muscle tissues or fascia, leading to muscle stiffness and
hence loss or failure of bodily systems1) and neuromuscular
dysfunction2). Treatment of MTrPs is aimed at relieving or
eliminating TrPs and include pharmacological approaches,
such as the administration of nonsteroidal anti-inflammatory
drugs (NSAIDs) in conjunction with muscle relaxants or
painkillers, and non-pharmacological approaches, such as
ischemic compression and massage3). Among the non-pharmacological
approaches, massage is considered an effective
treatment for MTrPs4)
