ABSTRACT

Objetivo: Determinar si la mialgia de esfuerzo en los antebrazos de los músicos está asociada a un trastorno de irrigación u oxigenación muscular condicionado por una alteración en la presión intracompartimental (PIC). Material y método: Se estudiaron 29 músicos con mialgia de esfuerzo en antebrazos y un grupo control de 9 músicos sanos. Se midió simultáneamente la presión en el compartimento extensor superficial del antebrazo y la oxigenación tisular mediante espectroscopia con luz casi-infrarroja. Las mediciones se realizaron antes, durante y después de realizar un trabajo dinámico de flexo-extensión contra resistencia de los dedos hasta la fatiga. Resultados: El valor medio de la PIC en reposo fue de 13,22 mmHg (grupo control) y de 12,42 mmHg (grupo mialgia). La PIC post-esfuerzo fue de 17,19 mmHg y de 14,83 mmHg. Los valores de la PIC no mostraron diferencias estadísticamente significativas entre los dos grupos. Se objetivaron diferencias significativas de oxihemoglobina entre los dos grupos en la fase de recuperación. Conclusiones: La mialgia de esfuerzo podría asociarse a una alteración en la oxigenación e irrigación tisular pero sin existir indicios de estar provocado por un aumento patológico de la PIC (AU)


Aim: investigate whether exertional myalgia in musician’s forearms is a disorder associated with a deficiency on muscle irrigation/oxygenation and whether this is determined by an increased intracompartmental pressure (ICP). Material and methods: We have studied 29 musicians with forearm’s exertional myalgia and a control group of 9 healthy players. In all them the ICP, measured in the forearm superficial extensor compartment, and the tissue oxygenation, by means of near-infrared spectroscopy, was simultaneously recorded. Measurements were taken before, during and after doing dynamic fingers flexion-extension work against resistance to fatigue. Results: The mean resting ICP was 13.22 mmHg (control group) and 12.42 mmHg (myalgia group). Postexertion ICP was 17.19 mmHg and 14.83 mmHg. The PIC values showed no statistically significant differences between the two groups. Significant discernible differences were seen in the amount of oxyhemoglobin between he two groups in the recovery phase. Conclusions: Exertional myalgia seems to be associated with an alteration in tissue oxygenation and irrigation but there are no indicators of being caused by a pathological increase in ICP (AU)

ABSTRACT

OBJECTIVE: To explore the effect of intravascular low level He-Ne laser irradiation on skin flap survival after orthotopic transplantation in avulsion injury. METHODS: Fifty eight cases suffered avulsion injury were treated by debridement and orthotopic transplantation of avulsed flap within 6 hours, 31 of them were received intravascular low level He-Ne laser irradiation and routine treatment, and 27 of them were received routine treatment as control group. RESULTS: The survival area and quality of avulsed flap in the experimental group were superior to that of control group after 15 days of operation, and the hemorheological items were markedly changed at 5 days after operation. CONCLUSION: The better flap survival after orthotopic transplantation in avulsion injury can be improved by intravascular low level He-Ne laser irradiation through changed superoxide dismutase activity and hemorheological items in optimal irradiation intensity.
