Ultrasound

Ultrasound is the use of common household current converted to an ultrasound wave by the combination of a transformer, transducer head, and oscillating circuit. The crystal in the transducer head creates the piezoelectric effect of the ultrasound wave which allows these waves to penetrate deep into the tissues. This can have many favorable thermal and non-thermal effects.

PHYSIOLOGICAL EFFECTS OF ULTRASOUND:

Increased metabolic rate of tissue
Increased extensibility of collagen
Increased blood flow and tissue healing
Increased joint range of motion
Decreased sensitivity of neural elements
Decreased pain and muscle spasms

INDICATIONS FOR ULTRASOUND:

Treatment of non-acute soft tissue injuries
Sub-acute and chronic inflammation
Tissue regeneration
Non-acute bursitis
Adhesive capsulitis
Scar tissue softening
Myositis
Nerve root irritation

CONTRAINDICATIONS FOR ULTRASOUND:

Neoplasms--active cancers
Circulatory disorders
Pregnant uterus or over reproductive organs
Areas of acute inflammation
Open wounds
Epiphysis of growing bones
Over or around pacemakers
Over areas of decreased sensation
Healing fractures
Feverish conditions
Also avoid brain, heart, eyes, and ears

COMMENTS:

Can be used in combination with electrical stimulation (Medco) or with 10% Hydrocortisone cream for Phonophoresis. Commonly used in conjunction with other modalities.
Can be used directly on skin surface with ultrasound gel or in water (immersed ultrasound)
PTC, Inc. clinical policy is to discontinue ultrasound after 10-12 treatments to a single area due to possible detrimental physiological effects.
