Ultrasound refers to mechanical vibrations which are essentially the same as sound waves but of a higher frequency. Such waves are beyond the waves of human hearing and can therefore be called ultrasonic.
Vibration merges with sound at frequencies around 20 Hz. Therapeutic Ultrasound frequency is 1 to 3 MHz.
Therapeutic Uses :
Pain Relief :- Ultrasound is used in low backache, Osteoartritis, tendinitis, Prolapsed intervertebral disc and many other conditions.
Acute tissue injury – Ultrasound is used in soft tissue and sport injury, occupational injury and Post natal injuries. It is used for perineal post-natal pain, for painful shoulders and for both neurogenic and chronic pain.
Scar Tissue :- Ultrasound improves the quality of scar tissue and excessive fibrous tissue. It is used in conditions like Dupuytren’s contracture and Plantar fascitis. Dupuytren’s contracture is a thickening and contracture of Palmar fascia typically affects the ring finger and may involve years later incompletely little finger.
Bone Injury :- Ultrasound therapy is used in the early diagnosis of stress fracture.
Chronic Indurated Oedema :- The mechanical effect of Ultrasound has an effect on chronic oedema and helps in its treatment .It also breakdown adhesions formed between adjacent structures.
Varicose Ulcers :- Ultrasound promotes healing of varicose ulcers and pressure sources.
