Comparison between effects of instrument-assisted soft tissue mobilization and manual myofascial release on pain, range of motion and function in myofascial pain syndrome of upper trapezius - A randomized controlled trial.

IASTM and manual MFR both are effective individually as treatment procedures for pain, PPT, range of motion, and function. Neither of the treatment options can be considered better that the other. The clinician can decide based on the availability of the instrument, training, patient's preference, and his/her comfort whether which of the two treatment methods should be used.
