Collagen changes and realignment induced by low-level laser therapy and low-intensity ultrasound in the calcaneal tendon.

Background And Objective: The treatment of calcaneal tendon injuries requires long-term rehabilitation. Ultrasound (US) and low-level laser therapy (LLLT) are the most used and studied physical agents in the treatment of tendon injuries; however, only a few studies examined the effects of the combination of US and LLLT. Therefore, the purpose of this study was to investigate which treatment (the exclusive or combined use of US and LLLT) most effectively contribute to tendon healing.

Effect of low level laser therapy (830 nm) with different therapy regimes on the process of tissue repair in partial lesion calcaneous tendon.

Background And Objective: Calcaneous tendon is one of the most damaged tendons, and its healing may last from weeks to months to be completed. In the search after speeding tendon repair, low intensity laser therapy has shown favorable effect. To assess the effect of low intensity laser therapy on the process of tissue repair in calcaneous tendon after undergoing a partial lesion.

Effects of a progressive loading exercise program on the bone and skeletal muscle properties of female osteopenic rats.

The aim of this study was to determine the effects of a progressive loading exercise program on the bone and skeletal muscle properties of female osteopenic rats. Forty female Wistar rats (12 weeks old) were divided into four groups (n=10): sham-operated sedentary (SS); osteopenic-sedentary (OS); sham-operated training (ST) and osteopenic training (OT). Osteopenia was induced by ovariectomy (OVX).
