This study demonstrates that low sound pressure level (LSPL) infrasound (12-20 Hz, <90 dB) applied for 30 minutes twice daily over six weeks significantly enhances bone healing in a rat femoral fracture model, as evidenced by improved radiographic union, higher bone mineral content (BMC) and density (BMD), and increased new bone formation, likely mediated by a neuro-osteogenic network involving increased calcitonin gene-related peptide (CGRP) and decreased neuropeptide Y (NPY) innervation in the fracture microenvironment. For medical professionals, these findings suggest that LSPL infrasound could serve as a non-invasive therapeutic tool to accelerate fracture healing and bone remodeling in clinical orthopedics, particularly for delayed or nonunion fractures, although further research is needed to optimize treatment parameters and confirm efficacy in human patients.

Owners of the Infrasound 8 device and CHI Palm might use them to help speed up the healing of broken bones, such as those caused by accidents or injuries. The study suggests that applying the device at low settings (Acute setting on the CHI Palm) for 30 minutes twice a day for six weeks can help bones heal faster and become stronger, with more bone growth and better bone structure in rats. Owners could expect quicker recovery and stronger bones in the treated area, but more research is needed to confirm efficacy in humans.
