Ultrasound therapy is most widely employed by physical
therapists, and has been an extremely popular therapy since the 1950s. When
ultrasound propagates through tissue, biophysical effects of both thermal
and non-thermal mechanical interactions take place at the same time.
Thermal Effects of Therapeutic Ultrasound
Ultrasound energy is absorbed by the tissue results in the conversion of
ultrasonic energy to heat. Thermal effects of ultrasound upon tissue may
include increased blood flow, reduction in muscle spasm, increased extensibility
of collagen fibers and a pro‐inflammatory response. However, excessive thermal
effects, seen in particular with higher ultrasound intensities, may damage
the tissue.
Non-thermal Effects of Therapeutic Ultrasound
Non-thermal effects of ultrasound can be divided into generating acoustic
cavitations, the formation of tiny gas bubbles as a result of ultrasound
vibration, and other mechanical effects. The cavitations can be classified
into stable cavitations and unstable cavitations.
Stable cavitations are described in which the bubble is
forced to oscillate its size and shape due to the change of ultrasonic pressure.
Acoustic streaming, localized liquid flow around the vibrating bubbles,
is another major effect. It can be distinguished between bulk streaming
and micro-streaming. It is the micro-streaming that can only alter cell
membrane permeability and stimulate the cell activity.
Unstable cavitations are described in which the bubble
collapses rapidly and produces a shock wave with very high local temperature
increase which produces toxic free radicals in the tissue.
Articular cartilage called shock absorber, since there
is no direct blood supply, it is generally hard to be repaired itself when
injured. Although there have been several approaches to the repair of injured
articular cartilage, current medical treatment is not able to give patients
satisfactory treatment.

TendonCARE Biophysics Hong Kong based Company provides beneficial solution,
optimized critical therapeutic ultrasound parameters is so important for
LIPUS application and healing. Physics of ultrasound parameter such as pulse
rate, pulse width, wavelength, intensity and know-how, all are critical
biophysical effects for healing.
Ultrasound treatment highlights:
-
* Relieve pain of Neuromuscular Disorder
* Healing of Articular Cartilage
* Reduce Muscle Spasms
* Reduce Resolution of Edema
* Improves Joints Immobility
* Improves Hamstring Flexibility
* Improves Blood Flow of Capillary
Applications of LIPUS
* Promoting bone fracture healing;
* Treating orthodontically induced root resorption;
* Regrow missing teeth;
* Enhancing mandibular growth in children with hemifacial microsomia;
* Promoting healing in various soft tissues such as Cartilage, Intervertebrl disc, etc;
* Improving muscle healing after laceration injury
* Improvement of peripheral nerve regeneration of neuronal axons
* Enhances cell proliferation and alters protein production in various kinds of cells such as endothelial cells, osteoblasts, chondrocytes, and fibroblasts
Ultrasound stimulates the production of more collagen which exists in soft tissue such as tendons and ligaments. Hence ultrasound accelerates the proliferative phase of tissue healing.

LIPUS is one of the physical agents that known to accelerate bone and tissue regeneration following injury (Heckman, Ryaby et al. 1994; Lu, Qin et al. 2006).
LIPUS has been accepted as an effective therapy for nonunion fractures and fresh fracture healing through an easy and non-invasive application (Azuma, Ito et al. 2001; Schortinghuis, Bronckers et al. 2005)
LIPUS has positive effects on axonal regeneration by in vivo peripheral nerve injury trials (Crisci and Ferreira 2002; Chang, Hsu et al. 2005).
Raso (Raso, Barbieri et al. 2005) have demonstrated that the locally applied ultrasound stimuli on the injured sciatic nerve rather than the untreated nerves of rats can effectively enhance the number of Schwann cell nuclei.
LIPUS has been used in conjunction with tissue engineered nerves in repairing
peripheral nerve defects, Chang (Chang, Hsu et al. 2005) demonstrated that
applying LIPUS on seeded Schwann cells within poly (D, L-lactic acid-co-glycolic
acid) conduits have a significantly greater number and area of regenerated
axons compared to the sham groups.
