Luciane A P Sande de Souza, Cyntia R J A De Baptista, Fernanda Brunelli, Valdeci C Dionisio.

Abstract
Objective: To investigate the occurrence and irradiation/overflow amount on the muscular activity of healthy individuals submitted to proprioceptive neuromuscular technique
Design and setting: experimental study with convenience sample
Seeting: physiotherapy university rehabilitation centre.
Subjects: Sixteen volunteers dexterous, healthy (8 men and 8 women), with 18 to 24 years (21± 1.61) were evaluated.
Procedures: Bilateral electromyography of the upper limbs and trunk muscles (anterior deltoid, posterior deltoid, pectoral major and external obliquous) were recorded during the proprioceptive neuromuscular facilitation movement pattern in left lower limb (diagonal of flexion/adduction/internal rotation. The electromyographic activity were obtained in 5 different conditions:(1) rest, (2) right upper limb movement in free diagonal of extension-adduction- internal rotation, (3) left lower limb diagonal of flexion, adduction and internal rotation, with upper limbs in rest, (4) left lower limb diagonal with contralateral upper limb having an attachment point, (5) right upper limb performing free diagonal 3, 6, and 9 seconds after lower limb isometric diagonal.
Results: There were differences between tested conditions for the most of muscles (p
