ABSTRACT
Introduction. The proprioceptive neuromuscular facilitation (PNF) is a physiotherapeutic concept based on muscle and joint proprioceptive stimulation. Among its principles, the irradiation is the reaction of the distinct regional muscle contractions to the position of the application of the motions. Objective. To investigate the presence of irradiated dorsiflexion and plantar flexion and the existing strength generated by them during application of PNF trunk motions. Methods. The study was conducted with 30 sedentary and female volunteers, the PNF motions of trunk flexion, and extension with the foot (right and left) positioned in a developed equipment coupled to the load cell, which measured the strength irradiated in Newton. Results. Most of the volunteers irradiated dorsal flexion in the performance of the flexion and plantar flexion during the extension motion, both presenting an average force of 8.942 N and 10.193 N, respectively. Conclusion. The distal irradiation in lower limbs became evident, reinforcing the therapeutic actions to the PNF indirect muscular activation.

Mentions: The data was collected in one single moment, according to volunteers availability, at morning or at afternoon. A familiarity with the motions was performed 48 hours before the study, but it did not involve any learning due to the given interval. Each volunteer seated at the same wooden chair with a backrest and without armrests, with the foot on the system, the knee flexion at 60° degrees on a foam wedge. Trunk flexion and extension motions were performed using the resistance PNF motion, evaluating both positioning feet, the left and the right one on the system at each motion. The motion of each foot was held in two trials, with one minute rest between them, considering the highest value and standard developed by this value. Between trunk flexion and extension motions, a ten-minute break was given in order to avoid fatigue and the decrease of the maximum developed force (Figure 3).
