Abstract.[Purpose] The purpose of this research was to clarify the effects of indirect treatment of proprioceptive neuromuscular facilitation (PNF).[Subjects] The subjects were thirty healthy male volunteers. Their mean age was 21.1 ± 1.1 years. [Methods] This study examined the extension force of the contralateral lower limb when manual isometric resistance exercise was performed by an upper limb at the start, middle, and final positions of PNF and shoulder flexion. A hand-held dynamometer measured the extension force of the contralateral lower limb.[Results] The extension force of the contralateral lower limb increased when an isometric resistance exercise was performed by an upper limb at the final position of the flexion-abduction-external rotation pattern of PNF.[Discussion] The extension force of the contralateral lower limb increased more with PNF movement than in shoulder flexion of an upper limb. The result suggests that isometric resistance exercise by an upper limb at the final position of PNF emphasized the "continue movement" and the systemic balance reaction occurred toward the side of the contralateral lower limb. This finding, therefore, could be applied to the treatment of patients having difficulty with moving their own lower limbs.

“…for instance, the mean frequency and the mean power of alpha band of EEG are higher at facilitating positions of the upper or the lower extremity than at neutral positon (Chida and Nakamura 1983: Hosokawa et al 1985). Both EEG and reaction time studies suggest that facilitating positions induce generalized activation of the central nervous system.…”

FUJITA, M. and NAKAMURA, R. The Effect of PNF Position of the Upper Extremity on Rapid Knee Extension. Tohoku J. exp. Med., 1986, 150 (1), [31][32][33][34][35] Premotor time (PMT) and maximum tension (FmaX) produced by isometric contraction of the left and the right quadriceps femoris for rapid knee extension were examined in 10 normal male subjects at two positions of the left upper extremity, neutral and facilitating position for the triceps brachii. Compared to the neutral position, PMT of the both sides decreased and FmaX increased at the facilitating position, while the contraction time did not change. It is assumed that the facilitating position brings about generalized activation of the central nervous system resulting in behavioral alertness. behavioral alertness ; force output ; PNF position ; reaction time It is empirically known that facilitating positions utilized in proprioceptive neuromuscular facilitation (PNF) technique make it easy for a subject to start and carry out patterned movements. Recent studies indicated that facilitating positions induced behavioral alertness, since premotor time (PMT) of the triceps brachii muscle, a latency from a response signal to the onset of EMG activities of the muscle, was short at the facilitating position compared to neutral or kinesiological reference position (Nakamura and Viel 1974;Taniguchi et al. 1980), and also indicated that vocal reaction time was faster at facilitating position of the upper or the lower extremity than at the neutral position (Nakamura 1983). Although facilitating positions generally decrease PMT, their effect on force output in a reacton time study has not been examined. In this study, we analyzed force output of rapid knee extension at two positions of the upper extremity, neutral and facilitating position for the triceps brachii (Nakamura and Viel 1974), and attempted to examine whether shortening of PMT was coupled with any change of force output. METHODSTen healthy male subjects aged from 27 to 50 years participated in the study. The experimental apparatus has been reported in detail (Nagasaki and Nakamura 1985). The subject sat on a chair with the trunk upright, and the hip and the knee flexed at 90 degrees. A strap with two ropes was attached to distal end of the leg. The one rope was connected

“…For instance, RT of the triceps brachii muscle for elbow extension is faster at facilitating position of the shoulder than at neutral position (Nakamura and Viel 1974;Nakamura 1976/77). This phenomenon is attributed to the shift of arousal level induced by the postural changes (Maria 1970, Nakamura 1983Hosokawa et al 1985). Previous studies showed that postural dependence of RT disappeared in patients with cerebellar lesion (Nakamura 1976/77), and reappeared transiently after proprioceptive neuromuscular facilitation (PNF) maneuver, a technique of physical therapy (Nakamura and Taniguchi 1980).…”

“…159 R. Nakamura and K.. Kosaka patients due to unsteadiness of their performance. Our recent study (Hosokawa et al 1985) suggested that the shift of arousal level due to postural changes could be detected by the measurement of mean power in alpha band of EEG. In this paper we examined the effect of postural changes on the mean power in alpha band of EEG before and after PNF maneuver in patients with spinocerebellar degeneration (SCD), and attempted to confirm the applicability of EEG topography instead of RT study.…”

“…The method to analyze the shift of mean power in alpha band of EEG due to postural changes was already reported (Hosokawa et al 1985). The patient sat on a chair with closed eyes and EEGs were recorded in two positions of the left lower extremity : neutral (N), the hip flexed at 90° and neutral rotation ; and facilitating (F), the left hip being passively maintained at 30° internal rotation.…”
