I. Treatment Schedule
You should comply with the recommended daily 20-minute
treatment period that has been prescribed by your physician.
Following this treatment schedule with low-intensity
ultrasound therapy can provide the clinical benefit of
healing your nonunion or accelerating the healing time of
your fracture as was shown in the device clinical trials.
Please note that ultrasound therapy is automatically shut
off after each treatment period. However, the transducer
should be removed from the RAF after each treatment
period to allow for proper cleaning and storage.
Use the device for one 20-minute treatment period each day
until your physician advises you to discontinue therapy. The
EXOGEN 4000+ device contains an internal patient usage
timer, which monitors and records the daily use of your device.
This record is available to your physician so that he/she can
evaluate your adherence with the daily treatment schedule.
J. Trouble Signals and Corrective Actions
