INTELECT LEGEND COMBO

Ultrasound Indications and Contraindications

Indications

Ultrasound for use in applying deep heat can be used for treatment of selected medical conditions such as the relief of pain,
muscle spasms and joint contractures. These conditions may be associated with adhesive capsulitis, bursitis with slight
calcification, myositis and soft tissue injuries. The Intelect

®

Legend Combo can provide therapeutic deep heating between

40 and 45° C in all of its operating modes, while using any of the applicators available for this device.

Contraindications

•• This device should not be used for symptomatic local pain relief unless etiology is established or unless a pain syndrome has 

been diagnosed.

•• This device should not be used when cancerous lesions are present in the treatment area.
•• This device should not be used when open wounds are present in the treatment area.
•• Other contraindications are patients suspected of carrying serious infectious disease and or disease where it is advisable, 

for general medical purposes, to suppress heat or fevers.

•• This device should not be used over or near bone growth centers until bone growth is complete.
•• This device should not be used over the thoracic area if the patient is using a cardiac pacemaker.
•• This device should not be used over a healing fracture.
•• This device should not be used over or applied to the eye.
•• This device should not be used over a pregnant uterus.
•• This device should not be used on ischemic tissues in individuals with vascular disease where the blood supply would be unable 

to follow the increase in metabolic demand and tissue necrosis might result.

•• Patients with an implanted neurostimulation device must not be treated with or be in close proximity to any shortwave diathermy, microwave 

diathermy, therapeutic ultrasound diathermy or laser diathermy anywhere on their body. Energy from diathermy (shortwave, microwave, 

ultrasound and laser) can be transferred through the implanted neurostimulation system, can cause tissue damage and can result in severe injury 

or death. Injury, damage or death can occur during diathermy therapy even if the implanted neurostimulation system is turned "off."
