El pisiforme, una nueva zona de desencadenamiento segmental de los contenidos cinesiológicos de la mano en la terapia Vojta. Aplicaciones en rehabilitación

Abstract

ObjectiveTo study the effect of pisiform bone stimulation in the segmental pattern of the hand in the overall coordination complexes of Vojta reflex locomotion therapy. Material and methodA clinical trial was conducted with 32 healthy adults (average 23.56 years, standard deviation 2.96 years) with causal sampling. Inclusion criteria: healthy subject blind to the intervention type. Measurement was by surface electromyography of non-voluntary contraction in microvolts of the fingers extensor muscle (ECD), stimulating the pisiform area separately in contrast and combination with other LR areas. ResultsPisiform stimulation activates significant contraction (11.73 μV), p=0.00 of the ECD in relation with the styloid area (4.83 μV) in the reflex rolling pattern (RR), this being less on the reflex creeping (RC) (4.46 μV), p=0.015 compared to the styloid area (2.49uV). It also significantly activates (p=0.00) the kinesiological main pattern components of the opposite stimulated segment (9.47uV). The measurement in the sitting position (9.45 μV) also shows significant differences with the resting state (p=0.00). ConclusionIsolated stimulation of the pisiform area in the reflex rolling pattern activates the segmental pattern on both sides of the hand. With this, the therapist has new aids that can be used during work when the segmental hand pattern is not accessible from other points. However, its potential therapeutic in rehabilitation with hand function alterations needs to be studied.
