Efectos del instrumento inybi en pacientes con cervicalgia mecánica crónica

Zusammenfassung

ABSTRACT: Aims.- To confirm that no differences exist between the application of the manual suboccipital muscle inhibition technique and the application of the INYBI instrument in the suboccipital musculature, and to verify that in both cases the patient improves in relation to the different variables analysed. Material and methods.- The study was a randomised double blind, longitudinal, prospective, controlled clinical trial involving a total of 58 subjects (45 women and 13 men) randomly distributed between two groups: the experimental group (29), with application of the INYBI instrument in the suboccipital musculature, and the control group (29), which was treated using the manual suboccipital muscle inhibition technique. In both groups, pre, post and post 45 min measures were taken of: the pain threshold on trigger points on the upper trapezius and rectus capitis posterior major, using a pressure algorithm; pain intensity, using a pain scale (VAS); cervical goniometry (Plaincode Clinometer); rotation of the atlas, using the atlas rotation FRT; and maximum mouth opening, using vernier callipers. Results.- No statistically significant differences were found between the experimental and control groups for any of the variables studied (p> 0.05). Pain at the trigger points in both the upper trapezius and the rectus capitis posterior major was observed to improve, with the more significant difference being noted at the trigger points of both trapezius muscles (p<0.001). Significant increases were also observed in cervical mobility in flexion, extension, left rotation and right lateral flexion (p<0.05). The results also indicated significant changes in mouth opening (p<0.05), atlas mobility in rotation (p<0.05) and the VAS pain scale (p<0.05). Conclusions.- The application of the “INYBI” instrument may substitute the manual suboccipital inhibition technique providing the physiotherapist deems it appropriate, and both the manual and instrumental techniques are indications for the treatment of chronic mechanical cervicalgia.
