A Systematic Review of the Soft-Tissue Connections Between Neck Muscles and Dura Mater: The Myodural Bridge.

STUDY DESIGN: Systematic review. OBJECTIVE: To elucidate the existence of soft tissue connections between the neck muscles and cervical dura mater. SUMMARY OF BACKGROUND DATA: Several studies discuss the existence of a cervical myodural bridge; however, conflicting data have been reported. METHODS: Searches were conducted in the PubMed, Web of Science, Cochrane Library, and PEDro databases. Studies reporting original data regarding the continuity of non-post-surgical soft tissue between the cervical muscles and dura mater were reviewed. Two reviewers independently selected articles, and a third one resolved disagreements. Another two researchers extracted the methodology of the study, the anatomical findings, and evaluated the quality of the studies using Quality Appraisal for Cadaveric Studies Scale. A different third researcher resolved disagreements. RESULTS: Twenty-six studies were included. A soft tissue connection between the rectus capitis posterior minor, the rectus capitis posterior major, and the obliquus capitis inferior muscles seems to be proved with a strong level of evidence for each one of them. Controversy exists about the possible communication between the dura mater and the upper trapezius, rhomboideus minor, serratus posterior superior, and splenius capitis by means of the ligamentum nuchae. Finally, there is limited evidence about the existence of a soft tissue connection between rectus capitis anterior muscle and the dura mater. CONCLUSION: There is a continuity of soft tissue between the cervical musculature and the cervical dura mater; this might have physiological, pathophysiological, and therapeutic implications, and going some way to explaining the effect of some therapies in craniocervical disorders. LEVEL OF EVIDENCE: N/A.

Movilidad lumbopélvica en pacientes estreñidos tras la maniobra hemodinámica abdominal modificada / No disponible

Introducción: El estreñimiento funcional es la patología más frecuente en Gastroenterología. Recientes estudios aseveran una presencia del 78% de dolores referidos al aparato locomotor de origen visceral. Objetivos: Evaluar la Maniobra Hemodinámica abdominal modificada (MHAM) en pacientes estreñidos a través del Umbral de dolor a la presión (UDP) en los niveles dorsales T10,T11 y T12, inclinometría para la flexión lumbar, el test de extensibilidad Sit and Reach y la valoración postural del paciente con el programa SAPO. Material y Métodos: Ensayo clínico aleatorizado controlado, a doble ciego en 20 pacientes (n=20); Grupo Control (GC: n=10) y Grupo Experimental (GE: n=10). Resultados: Algometría T11: en el GE la diferencia media fue de 1,05 kg (IC95%=0,501 a 1,603; p=0,001; d Cohen= 0,84). Algometría T12: en el GE la diferencia fue 1,23 kg (IC95%=0,499 a 1,969; p=0,002 significativa; d Cohen=0,89). Inclinometría T12: en el GE se produjo un incremento medio de 10,4º (IC 95%=7,59 a 13,21º; p<0,001; d Cohen=0,94).Test Sit and Reach: en el GE el aumento medio fue de 3,47cm (IC95%= 2,35 a 4,58 cm; p<0,001; d Cohen=0,77). Conclusiones: La aplicación de la Maniobra Hemodinámica Abdominal Modificada en pacientes con estreñimiento funcional genera cambios inmediatos aumentando la tolerancia al dolor en las vértebras T11 y T12, aumentando la flexión lumbar y mejorando la extensibilidad de los miembros inferiores (AU)
