How effective is therapeutic ultrasound (TUS) in the management of non-specific, chronic, low-back pain (LBP), ie, lasting longer than 12 weeks?
Most of the studies only provided short-term follow up (a few days to a few weeks). Not all recommended outcome measures for studies on LBP (eg, pain and back-specific function) were measured by all studies. Ultrasound application parameters and dose were inconsistently reported, which meant no conclusions on the most effective dose could be made.
TUS is frequently used by physiotherapists in the treatment of LBP, using vibration to deliver heat and energy to muscles, ligaments, tendons and bones, with a goal of reducing pain and speeding healing.
