Sustained Acoustic Medicine for Symptomatic Treatment of Knee Pain Related to Osteoarthritis

Summary

The purpose of this study is to assess the ability of long-duration low intensity therapeutic ultrasound (LITUS) to alleviate knee Osteoarthritis pain over a 24-week period. The primary objective of this study is to evaluate the analgesic effect of LITUS in subjects suffering from knee Osteoarthritis pain. Secondary objectives are to assess the ability of LITUS to improve joint function.

* Report that knee pain 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 ultrasound gel provided to the subject at the initiation of the study
* Are deemed appropriate by their physician or by the study site physician to participate.

* Not use or initiate use of opioid and/or non-opioid analgesic medications.
* Be willing to discontinue any other interventional treatment modalities on the knee during the study period (e.g., transcutaneous electrical nerve stimulation, electronic muscle stimulation, traditional ultrasound).
