Action of therapeutic laser and ultrasound in peripheral nerve regeneration
نویسندگان
چکیده
OBJECTIVE To assess the efficacy of early therapeutic laser and ultrasound in the regeneration process of an injury in rats. METHODS We used 24 rats. Eighteen underwent surgery for sciatic nerve compression by a hemostat above the popliteal fossa. The animals were divided into three groups of six animals each. Normal control group. GI: Injured control without therapeutic intervention. GII: laser ArGaAl therapeutic intervention. GIII: therapeutic intervention of Pulsed Ultrasound. We begin therapeutic interventions 24 hours after injury, with daily applications for a period of fourteen consecutive days. RESULTS IN ASSESSING THE GIRTH OF THE MUSCLES OF THE RIGHT THEY, THE FOLLOWING AVERAGE DECREASE (IN MM) FOR EACH GI: 0.45, GII: 0.42, GIII: 0.40 In relation to travel time, both GII and GIII presented significant difference when compared to GI. In the final evaluation of the IFC, GII excelled in the GIII. As for the healing observed, a major great improvement was observed in GII and GIII. CONCLUSION The results showed that nerve recovery was higher with the laser application. Level of evidence II, Therapeutic Studies - Investigation of the results of treatment.

A B S T R A C TIntroduction: Peripheral nerve injury is a common disorder and leads to permanent neurological defects. Schwann cells have been shown to have nerve repair after being transplanted in peripheral nerve injury. The aim of this study was to determine the beneficial effect of allograft Schwann cells on electrophysiological outcome after transection of the sciatic nerve in rats.Methods...
متن کاملThe role of the desert hedgehog signaling pathway during degeneration and regeneration of peripheral nerves
The desert hedgehog (Dhh) signaling pathway is involved in the development of peripheral nerves (PNs). Dhh-null mice show abnormal neuronal development and perineurial barrier function. As it was previously shown that dhh is mainly expressed in developmental nerves and Sonic hedgehog protein (dhh homologous) has therapeutic effects in neuronal survival, we attempted to investigate the possible ...
