Effect of Two Osteopathic Techniques on Thickness of Paravertebral Muscles of the Lumbar Spine

The objective of this randomized controlled trial is to describe the effect of two osteopathic techniques - \"high velocity, low amplitude\" (HVLA) and muscle energy (ME) - on thickness, activation, strength, pressure pain threshold (PPT) of the paravertebral muscles at the lumbar spine, as well as the peak plantar pressures immediately and after a two-day follow-up. The muscle thickness of the paravertebral muscles at the lumbar spine, namely internal oblique, external oblique and transversus abdominis can be altered after the application of \'high-velocity low-amplitude\'(HVLA)and \'muscle energy\' (ME)techniques immediately and after a two-day follow-up.
