| Definition |
Ultrasound is a deep penetrating modality with both thermal and non-thermal (mechanical and chemical) effects. Piezoelectric crystals contract, expand, and vibrate, creating ultrasonic waves that penetrate down to bone, resulting in heat. Gel is the most common coupling medium utilized and is indicated for localized treatment. Water also may be used, especially in treating overbony areas like the hand and foot. The sound wave may be administered continuously or intermittently (pulsed). The pulsed sequence allows for minimal thermal effect, which allows usage in the acute phase of injury. The frequency of the crystal determines the depth of penetration. One mHz allows penetration to deep areas and 3 mHz allows treatment of superficial regions. The optimal intensity is 5.5 waves per cm2, and continuous motion must be employed in treating areas directly over bone to prevent the possibility of a periosteal burn.

| Context |
For chronic plantar fascititis and heelspur syndrome, tendinitis, or sesamoiditis, phonophoresis is of great benefit.22, 31 For chronic joint post-traumatic pain and stiffness ultrasound is beneficial. Ultrasound and electrical stimulation may be used together as an effective means to break the pain-spasm cycle
