Résumé
Transcranial Doppler can be used for diagnosing,monitoring,identifying the site of arterial occlusion,selecting appropriate cases for thrombolysis,and monitoring arterial recanalization during intravenous thrombolysis,and intra-arterial and intravenous thrombolysis with recombinant tissue plasminogen activator,The continuous monitoring of low frequency transcranial ultrasound has the effect of assisted thrombolysis;however,there are still controversies on the frequencies used in clinical practice.Transcranial Doppler assisted with microbubble contrast agent may further enhance the effect of thrombolysis.
Résumé
@#ObjectiveTo investigate the therapeutic effectiveness of low-power laser on myofascial pain syndrome. Methods73 self-controlled patients with myofascial pain syndrome were irradiated on myofascial trigger points with Nd:YAG laser in wavelength 830nm, power 500mW, 20 minutes per day for 5 times. At pre-and post-treatment,pain intensity and pressure pain of myofascial trigger points were checked. ResultsAfter treatment, score of pain intensity was reduced signficantly from (7.24±2.41) to (2.21±1.22) (P<0.001). The pressure pain of myofascial trigger points were improved . Conclusions Low-power laser can reduce the pain intensity and increase the pressure pain threshold of myoficial trigger points.
