PROPRIOCEPTIVE NEUROMUSCULAR ELECTRICALLY STIMULATED FACILITATI ON INTEGRATING NMES INTO YOUR PNF PRACTICE
Abstract ：Both Proprioceptive Neuromuscular Facilitation (PNF) and Neuromuscular Electrical Stimulation (NMES) use the same underlying physiological principles to evoke amot or response .
Therapists can utilize NMES to tap into these principles when manual techniquesal one are not enought to elicit an optimal motor
contraction. While many PNF techniques depend on the patient ' s ability to voluntarily contract a muscle , NMES does not require
voluntary effort . Like manual contacts , electrodes can be thought
of as ' electrical contacts ' that increase the therapists ' ability to maximize proprioceptive facilitation. The stronger the muscle
contraction, the stronger the facilitation, and NMES provids the
ability to induce st ronger contractions , and thus , greater
facilitation in the weak patient . With advances in the understanding of neural plasticity, the brain is now of ten the
target of treatment, rather than muscles . NMES has traditionally be enused to reduce secondary peripheral impairments , but it can also be used to help reactivate existing neural pathways in the
brain that were temporarily rendered inaccessible , or to encour age cortical reorganization in the case of permanent brain damage.
While NMES can be used alone , when combined with PNF, the two together are better able to drive the be havioral signals that are
thought to promote neural plasticity and result in increased
function. This paper be gins by revie wing NMES principles to
provide the basis for discussing the combined use of NMES and PNF. The paper then presents : 1) the use of NMES to manage
peripheral dysfunction to address secondary impairments ; 2) the
use of NMES integrated with PNF procedures and techniques to manage central issues ; 3) research on combining PNF and NMES;
4) augmenting PNF manual therapy with NMES; and f inally, 5)
adescription of neuroplasticity research and its application to
integrating PNF and NMES.

Neurophysiological remote rebound effects of are resistive static
contraction using a Proprioceptive Neuromuscular Facilitation
pattern in the midrange of pelvic motion of posterior depression on the soleus H-reflex
Shiratani Tomoko, Arai Mitsuo, Kuruma Hironobu, Hobara Rui,
1. Introduction/ Background
With respect to the ascending effects of a resistive static
contraction of a pelvic depressors technique (RSCPD) using a
proprioceptive neuromuscular facilitation pattern in the mid-range
of pelvic motion of posterior depression, we found that the
neurophysiological remote rebound effects (RRE) induced by RSCPD on the he flexor carpi radialis H-reflex initially caused
reflexive inhibition during RSCPDT, followed by a gradual excitation after RSCPD in one case (Arai et al . ,2002) . The purpose of this
study was to compare the neurophysiological effects of descending remote after effects (RAE) of the RSCPD on the soleus (SOL)
H-reflex compared with the contralateral resistive exercise (RCE)
of the upper ankle plantar muscles in the side-lying position.
2. Materials and Methods
The effects of order were controlled by randomly assigning
numbers taken from a table of random numbers for the order of
the resistive static contraction (RCE, RSCPD) for each of fifteen normal subjects . The SOL H-reflex was measured at rest , during
each resistive exercise and after each resistive exercise . For
comparison, each H-reflex amplitude were normalized to the
corresponding a max M-waves (Mmax ) H-reflexes , which was
expressed by the ratio of H/Mmax (H/Mmax) .
A three way ANOVA for the H/Mmax showed that the technique
and time course produced a main effect ( exercise ; F ( 1, 132) =1. 88 p<0. 05; time course ; F ( 11, 132) =54. 53 p<0. 01) . RSCPD was significantly facilitated compared with the RCE. The interaction between technique and time course was also significant for the
H/Mmax( F ( 11, 132) =1. 94, p< 0. 01) . The relationship between
the H/Mmax and the time course in the RSCPD was best fitted by a single or derpolynomial equation ( y=0. 012x＋ 0. 162 ( p=0. 049). Gradual escalati on trend was observed RSCPD. Significant polynomial was not observedin RCE. A three way ANOVA f or the
H/Mmax showed t hat the technique and time course produced a main effect ( exercise ; F ( 1, 132) =1. 88 p<0. 05; time course ; F ( 11, 132) =54. 53 p<0. 01) . RSCPD was significantly facilitated
compared with the RCE. The interaction between technique and time course was also significant for the H/Mmax ( F ( 11, 132)
=1. 94, p< 0. 01) .
According to the significant facilitation of the RSCPD compared with the RCE of the right right plantar flexors , descending effects was
larger than the cross-education in this study.

Tetsuaki Sumida, Chihiro Sumida, Yasuhiro Harada
Abstract ：The purpose of this study was to determine the
aftereffects of resistive static contraction of the pelvic depressors (SCPD) or the anterior elevators (SCAE) using a proprioceptive
neuromuscular facilitation (PNF) pattern in the midrange of pelvic
motion to i mprove restricted hip extension. Thirty six or thopedic
disease patients (mean age : 70. 4 years , SD: 12. 9) at one
hospital were randomly as signed to the sustained stretch (SS) of
the hip flexors group, the SCPD group, or the SCAE group. The
change active range of motion (AROM) after each intervention was
calculated incomparison with AROM before the intervention. A one way ANOVA for the change in AROM revealed a significant differene
between the groups ( p<. 05) . Scheffé ' s test revealed that the
SCPD group and SCAE group showed signific ant improvements
compared to the SS group ( p<. 05) . The results of this study
suggest that use of the SCPD and SCAE may be effective approaches to improve the AROM of hipextension in the or thopedic

The after-effects of static contraction facilitation techniques of the
pelvic depressors while in the different sidelying position on the
improvement of the weight bearing of the affected side in the
standing posture in orthopedic patients

Abstract： The purpose of this study was to determine the after- effects of resistive static contraction of the pelvic depressos ( SCPD) on the unaffected or affected side while indifferent side-lying positions in orthopedic patients who were asked to shift to full weight bearing on the affected side in the standing posture . Eighteen subjects (mean age =79. 0 years , SD=12. 4) were randomly as signe d to the SCPD ( unaffected) , SCPD ( affected) or repeated weight shift exercise ( RWSE) groups where possible .
One way ANOVA demonstrated a significant difference between
groups based upon the percentage improvement in weight bearing.
Scheffé ' s post hoc test revealed that the SCPD for the unaffected and affected groups showed significant improvements compared with the RWSE group ( p<0. 05) . With respect to the weight bearing pain and feeling of unease , there were no significant differences between the three groups . These results suggest that SCPD may have immediate after-effects for increasing weight bearing of the affected side, and does not cause pain or a feeling of
unease on the affected side despite increased weight bearing.

Yoshimi Tanaka, Chiho Shimizu, Keisuke Kuwada, Yasuhiro Harada
Abstract：The purpose of this study was to investigate the effects of resistive static muscle contraction using a Proprioceptive
Neuromuscular Facilitation pattern in the mid-range of scapular anterior elevation ( SSCAET) or posterior depression ( SSCPDT) in
side-lying one xcitability of the upper soleus H-reflex . Forty healthy subjects ( mean age =30. 5 years ,SD=8. 0) were randomly as signed to the SSCAET group, SSCPDT group, Handgrip ( HG) group, or the Rest group. H-reflex amplitudes before, during and after each technique were measured every 20 seconds for 3 minutes . The results of repeated ANOVA in comparison of the amplitudes of the H-reflexes showed significant effects of both the
timecourse and group ( p<0. 05) . The interaction between group and timecourse was significant ( p<0. 05) . Post hoc analyis revealed significant effects on H-reflex during SSCAET and SSCPDT compared with the Rest group. The results of this study suggest that facilitation of the central nervous system occurs during resistive static contraction of the ipsilateral upper trunk muscles .

Effects of resistive static contraction in the mid-range pelvic motion on the soleus H-reflex
Chiho Shimizu, Yoshimi Tanaka, Keisuke Kuwada, Yasuhiro Harada
Abstract：Previous studies have reported that the application of resistive static muscle contraction with manual resistance using a Proprioceptive Neuromuscular Facilitation pattern in the mid-range pelvic posterior depression technique ( SCPDT) have improved the range of motion. However, the detailed mechanism remains unclear. The purpose of this study was to investigate the effects of
SCPDT based upon detection of changes of the H-reflex amplitude in the ipsilateral soleus muscle . Thirty one healthy subjects without neurological deficits were randomly as signed to SCPDT, sustained stretch ( SS) , or rest groups . The H-reflex amplitude of
the resisted side soleus muscle of each subject using an evoked pot ential measuring system ( mode lMEB9102) was measured. The H-reflex amplitudes before , during and after each technique were measured every 20 seconds for three minutes . The results of repeated ANOVA for the amplitude of the H-reflex showed significant group effects( p<0. 05) . The interaction between the group and timecourse was significant ( p<0. 01) .Post hoc analysis revealed significant effects on H-reflex during SCPDT compared with the SS and rest groups ( p<0. 01) . These results suggest that
the neurophysiological effects of the remote parts were evident during static contraction of the lower trunk.
