These two types of self-massage stick,
are however, a bit heavy and, relatively rigid (non-elasticproperty) when performing the self-massage. The Wilai
massage stickTM is a lightweight device especially invented
for self-massage and is made from an aluminum shaft with
a 1-inch diameter bent into a shape resembling a hook. The
curve of the stick was designed according to ergonomics
principles to enhance gripping and handling while performing
self-massage. The tip of the stick is slightly raised and
has a wooden massage ball that is 1.2 inches in diameter. A
preliminary study suggested that it could decrease pain and
increase active range of motion (AROM) in patients with upper
back pain8). An experimental study with a control group
and appropriate sample size has not been conducted to verify
these effects. Therefore, the objective of the present study
was to evaluate the effectiveness of traditional Thai massage
using a Wilai massage stickTM in comparison with the
administration of ibuprofen in reducing pain intensity and
tissue hardness and in increasing the pressure pain threshold
(PPT) and cervical range of motion (CROM) in patients with
upper back pain associated with MTrPs.
