Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18-80 with physician-diagnosed bone fractures and moderate pain levels that impact their quality of life.
✕Probably not a fit
Patients with severe pain requiring opioid analgesics or those currently using other interventional treatments may not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This study evaluates the effectiveness of a Sustained Acoustic Medicine (SAM) device combined with a diclofenac patch in alleviating pain associated with bone fractures over a 12-week period. Participants will self-administer the treatment for four hours daily while reporting their pain scores before, during, and after treatment. The study aims to recruit over 90 subjects from local communities, focusing on those who experience significant pain affecting their quality of life. The primary goal is to assess the analgesic effects of low-intensity therapeutic ultrasound on fracture-related pain.
Why it matters
Potential benefit: If successful, this approach could provide a non-invasive and effective pain management option for patients with bone fractures.
How similar studies have gone: While the use of low-intensity ultrasound for pain management is emerging, this specific combination of SAM and diclofenac is relatively novel and has not been extensively tested in prior studies.

Inclusion Criteria: * Have physician-diagnosed bone fracture * Are between 18-80 years of age * Report a pain score between 3-7 (range: 0-10) prior to enrolment * Report that pain from fracture negatively affects quality of life * Are willing not to use any cream, gel, or topical solution during the administration of treatment other than the approved treatment provided to the subject at the initiation of the study * Are deemed appropriate by their physician or by the study site physician to participate. * Be willing and able to self-administer treatment daily within their place of residence or during normal daily activity, excluding bathing, showering, or other water activities which may result in submersion of the study device. * Not use or initiate opioid and/or non-opioid analgesic medications. * Be willing to discontinue any other interventional treatment modalities on the affected area during the study period (e.g., transcutaneous electrical nerve stimulation, electronic muscle stimulation, traditional ultrasound). Exclusion Criteria: * Cannot successfully demonstrate the ability to put on and take off the device. * Displays any condition which, in the judgment of the investigator, would make participation in the study unacceptable including, but not limited to, the subject's ability to understand and follow instructions. * Participated in a clinical trial for an investigational drug and/or agent within 30 days prior to screening. * Is pregnant. * Is a prisoner. * Is non-ambulatory (unable to walk). * Has a pacemaker. * Has a malignancy in the treatment area. * Has an active infection, open sores, or wounds in the treatment area. * Has impaired sensation in the treatment area, such as caused by chemotherapy or anesthesia. * Has a known neuropathy (disease of the brain or spinal nerves). * Has a hereditary disposition (tendency) for excessive bleeding (hemorrhage). * Are currently taking steroids.
