Efectos del dispositivo inybi en sujetos con acortamiento de isquiosurales

Résumé

Objectives To discern whether the application of the INYBI instrument in the suboccipital musculature is comparable to the application of the manual technique and to determine that there are no differences in the results obtained in the variables examined in patients with ischiosural musculature shortening. Materials and methods Randomized, double-blind, longitudinal, prospective, and controlled trial. A total of 40 subjects were included in the study (12 women and 28 men), randomly distributed in two groups: experimental (20), which received the INYBI instrumental application in the suboccipital musculature; and control (20), which received the manual technique of inhibition of the suboccipital musculature. Pre- and post- and post-20-mins measurements of the cervical goniometry were taken on both groups for flexion amplitude (Clinometer Plaincode); modified Schober's test modified for lumbar flexion amplitude; fingertip-to-floor test for trunk flexion amplitude; extended leg elevation test (digital and manual measurement) for hip flexion amplitude; and the width of the opening of the mouth using a slide gauge. Results In none of the variables studied were there statistically significant differences between the experimental group and the control group (p> 0.05). In the total sample, we found significant differences between the pre-, post- and post-20-mins moments in cervical flexion (p <0.001) and Schober’s test (p <0.05); and we found significant differences between the pre- and post-20-mins moment in the fingertip-to-floor test (P <0.05), the extended leg elevation test (p <0.05) (in both legs and with digital and manual measurement) and in the opening of the mouth (p <0.05). Conclusions Inhibition of the suboccipital musculature produces changes in the shortening of the posterior muscle chain and there are no significant differences between the application of the manual technique and the application of the INYBI instrument. The INYBI device has beneficial effects in the treatment of ischiosural musculature shortening.
