Randomized Controlled Trial Comparative Study
Low-frequency high-intensity versus medium-frequency low-intensity combined therapy in the management of active myofascial trigger points: A randomized controlled trial.
Electrotherapeutic modalities have proven to be one of the best therapeutic options for myofascial pain syndrome, targeting the myofascial trigger points (MTrPs). Combined therapy (CT) is described with paucity in literature as the application of ultrasound (US) and electrical stimulating current concurrently and at the same site. ⋯ Within the scope of this study, both CT modalities were effective in increasing PPT and cervical lateral flexion ROM. Nonetheless, low-frequency, high-intensity burst-TENS-CT was shown to be superior over the medium-frequency, low-intensity AMF-CT in terms of reducing pain sensitivity and increasing ROM.
