LBP
CHRONIC LOWER BACK PAIN, INFLAMMATION, SECONDARY, FATTY INFILTRATION, ADHESIONS
This study has limitations, such as only using a percussion frequency of 30 Hz. It will be interesting to measure the effect of different frequencies and different location of PT on TLF in the future. Moreover, the secondary outcomes were performed by two researchers who were not blinded, and this study did not measure the physical activity level of participants, which carries a degree of risk of bias. Furthermore, the participants in this study were young, healthy males, so the results need to be generalized with caution for women and other populations. In future studies, validation of the long-term effects of PT on TLF in patients with chronic lower back pain is necessary because TLF in patients with LBP is fibrotic or dense due to inflammation, fatty infiltration, and adhesions.
