Ultrasound is a treatment that can be used to help ease the pain of soft tissue injuries. It involves the use of high frequency sound waves applied through a gel on the skin of an injured area. These sound waves travel 3-4cm through the skin and are absorbed into the area, giving a ‘micro tissue massage’.
This treatment is suggested to have effects due to both heat and the physical nature of sound waves.
- Thermal effects cause increased blood flow, decreased muscle spasm and increased stretch of muscle fibres.
- Physical effects of Ultrasound cause vibration and changes in pressure. This causes an increased movement of proteins both in and out of the cell which have been demonstrated to improve healing.
