Abstract
Leung MC, Ng GY, Yip KK. Effect of ultrasound on acute inflammation of transected
medial collateral ligaments. Arch Phys Med Rehabil 2004;85:963–6.
Objective
To evaluate the effect of therapeutic ultrasound on the acute inflammation of soft-tissue
injuries by measuring the levels of prostaglandin E2 (PGE2) and leukotriene B4 (LTB4).
Design
Randomized, case-control study.
Setting
Laboratory animal facility.
Animals
Thirty 3-month-old male Sprague-Dawley rats.
Intervention
Rats with medial collateral ligament transection were given 5 minutes of pulsed ultrasound
therapy (1:4) daily, with different durations (1, 5, 10d) and intensities (0, 0.5,
1.5, 2.3W/cm2).
Main outcome measures
Levels of PGE2 and LTB4.
Results
The levels of PGE2 and LTB4 were higher in all intensity subgroups that received 2.3W/cm2 intensity on postinjury day 2. On postinjury day 11, LTB4 was significantly decreased, but PGE2 was significantly increased.
Conclusions
Pulsed ultrasound therapy may stimulate inflammation of acute ligament injury.
