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.
There have been frequent reports that ultrasound has beneficial effect on
the repair of bone fracture and soft tissue healing including articular
cartilage. TendonCARE provides flexible and beneficial
solution, optimized critical therapeutic ultrasound parameters such as pulse
rate, pulse width, wavelength, intensity and know-how for best biophysical
effects.
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.
Ultrasound therapy does not have Anti-inflammatory effects, please don’t stop your medical advice.

超聲波治療儀
是物理治療師最常使用的治療工具之一，主要用於治療軟組織損傷，例如肌肉、韌帶、肌腱或關節膜的損傷。超聲波是由電流通過晶體而產生的高頻率聲波，當超聲波遇到纖維組織時的振動會引起輕微熱量。它通過治療師手上的一個圓形金屬頭，直接聚集在疼痛的部位及按摩。 超聲波能以超聲波偶合凝膠透過皮膚深入軟組織內部，加速進微絲血管的循環； 不同於手力推拿, 對於受傷部位不會加深創傷 (因用力擠壓而做成微絲血管破裂) 及在治療過程中不會疼楚卻能加速痊癒。
超聲波按摩有速進微絲血管循環(消腫)、活血化瘀、鎮痛作用
每秒1百萬(1Mhz)次的高頻機械震動
1．可引起組織细胞内物質運動，是一種微细的按摩作用，具有鎮痛作用。
2．可產生細胞漿流動；刺激細胞半透膜的擴散和膜渗透性，具有消腫作用。
3．加强血液和淋巴循環，加速去瘀促進新陳代謝。
4．低強度脈衝超聲波促進細胞增殖，並改變蛋白生產各種細胞，如內皮細胞，成骨細胞，軟骨細胞和成纖維細胞
