Investigation of alpha band of the electroencephalogram before and after a task of proprioceptive neuromuscular facilitation

Abstract

The proprioceptive neuromuscular facilitation (PNF) sets up a feature of treatment developed with the objective to facilitate and improve the motor performance. The aim of this study was to investigate in healthy female individuals the effects of electrophysiological of a diagonal of the PNF upper limb. The sample consisted of 30 female participants aged between 18 to 28 years, randomly divided into 3 groups (G1, G2, and G3). The three groups had 2 moments of electroencephalographic signal detection, before and after the task. The statistical neurophysiological design allowed the analysis of the relative power of alpha band in three leads (Fz, F7, and F8). Thus, a three-way mixed factorial analysis of variance (ANOVA) was performed to investigate the factor inter subjects (groups) and intrasubjects (areas and moments), a two-way ANOVA to investigate the interactions between the three factors, and a one-way ANOVA to analyze separately the factors time and area. A P≤0.05 was considered as significance level. The results showed significant increase of alpha band in the three groups analyzed, being more evident to the G2 group. Therefore, the PNF can be considered favorable also in relation to the cortical behavior, reinforcing its use in rehabilitation processes, especially in the clinical practice of physiotherapy.

Effect of proprioceptive neuromuscular facilitation technique on the treatment of frozen shoulder: a pilot randomized controlled trial

“…PNF technique emphasizes diagonal movement according to the patient’s rehabilitation goals. Here, the patient controls and relaxes, enhancing their ability to recover their perception and control of the diseased area [ 28 , 29 ]. PNF technique was also able to closely restore patients’ daily living ability, thus mobilizing their recovery [ 30 ].…”

“…PNF technique introduces resistance training, where patients need to coordinate their overall structure and movement to resist the motion given. This training can mobilize the diseased tissues so that that they could be restored through gradual training [ 29 ].…”

Efficacy and safety of proprioceptive neuromuscular facilitation for chronic low back pain: A meta-analysis of randomized controlled trials

“…[ 13 - 16 ] Proprioceptive neuromuscular facilitation was primarily developed by Dr. Herman Kabat and his collaborators in 1940s[ 17 ] and is used for numerous neurologic and musculoskeletal diseases. [ 18 ] It was reported that PNF could promote neuromuscular responses through stimulating proprioceptors,[ 19 , 20 ] improve muscular strength,[ 21 , 22 ] joint stability, mobility,[ 23 - 27 ] neuromuscular control, and coordination, consequently improving the overall functional ability of patients with CLBP. [ 28 - 30 ] However, the evidence on PNF for the management of CLBP is not sufficient.…”
