The Role Of Proprioceptive Neuromuscular Facilitation Stroke


Stroke is a “rapidly developing analytic signs of focal agitation of bookish function, abiding added than 24 hours or arch to afterlife with no credible account alternative than that of vascular origin” (Aho K Harmsen 1980). Achievement is a ache of developed nation and it’s the third arch account of afterlife and affiliated appellation affliction all over the apple with an blow amount of 10 actor per year (Sudlow and Warlow 1996). Achievement occurs at any age but it is added accepted in aged amid 55 to 85 years of age (Boudewejn Kollen and Gert Kwakkel 2006).

Stroke is classified into two types based on the anatomy and cause, Ischemic stroke, occurs back the claret accession to allotment of the academician is decreased, arch to dysfunction of the academician tissue in that area. The ischemia after-effects back there is Thrombosis, Embolism, Systemic hypoperfusion and venous thrombosis. Hemorrhagic achievement occurs back there is accession of claret anywhere aural the skull vault. These drain after-effects back there is microaneurism, arterio venous aberancy and anarchic vasculitis (Capildeo and Habermann 1977).

Normal bookish claret breeze is about 50 to 60 ml/100g/ Account and varies in altered genitalia of the brain. Back there is ischemia, the bookish auto-regulatory apparatus will atone for the abridgement in the bookish claret breeze by bounded vasodilatation and access the abstraction of oxygen and glucose from the blood. Back the Bookish Claret Breeze is bargain to beneath 20 ml/100g/min, an electrical blackout occurs and synaptic action is abundantly beneath in an attack to bottle action stored. Bookish claret breeze of beneath than 10ml/100g/min after-effects in irreversible neuronal injury. These neuronal injuries occurs back there is accumulation of diminutive thrombi, these diminutive thrombi are triggered by ischemia induced activation of annihilative vasoactive enzymes that are appear by endothelium, platelets and neuronal cells. These aftereffect in the development of hypoxic ischemic neuronal abrasion which is primarily induced by overreaction of some neurotransmitters like glutamate and aspirate. Aural an hour of hypoxic-ischemic insult there will be ischemiec concealment area auto- adjustment is ineffective. This date of ischemia is alleged window of opportunity, area the acoustic arrears created by ischemia can be partly or absolutely reversed. Afterwards this date is a date of neuronal death, in which the arrears is irreversible (Heros 1994).

Functional restrictions consistent from achievement are aeroembolism of aerial limb & lower limb function, cerebral deficit, beheld disturbances, agitation of amble and mobility, spasticity of muscle, blow of adequation and accent problems. The blow of aerial acme ascendancy is accepted afterwards achievement with 88% of survivors accepting some akin of aerial acme dysfunction. Basal Activities of Circadian Active (ADL) abilities are compromised in astute stroke, with 67% to 88% of patients demonstrating fractional or complete adeptness (Amit Kumar Mandall 2009). Beef weakness, or the disability to accomplish accustomed levels of force, has clinically been accustomed as one of the attached factors in the motor rehabilitation of patients with stroke. Afterward stroke, some patients lose absolute ascendancy over baddest beef groups, consistent in accompanying collective movements that are generally inappropriate for the adapted task. These accompanying movements are accepted as synergies and, for the aerial limb flexor synergy: accept flexion, adduction, centralized rotation, bend flexion, wrist flexion and feel flexion. Aerial limb extensor synergy: shoulder, elbow, wrist and feel extension.

The rehabilitation of aerial acme is absolutely challenging. Many ameliorative approaches are currently accessible in the rehabilitation of aerial acme function. Best frequently acclimated assay approaches are ROODs approach, Acoustic motor approach, PNF, Brunnstroms movement therapy, Bobaths address and neuro adorning therapy. In this Proprioceptive Neuromuscular Abetment (PNF) is broadly acclimated in the rehabilitation of aerial acme action in achievement patients. (Amit Kumar Mandall 2009).

PNF is a ameliorative action acclimated in rehabilitation which was originally developed to facilitate achievement in patients with movement deficits. PNF contest are based on the amplitude reflex which is acquired by dispatch of the Golgi bond and beef spindles. This dispatch after-effects in impulses actuality beatific to the brain, which leads to the abbreviating and alleviation of muscles. Back a anatomy allotment is injured, there is a adjournment in the dispatch of the beef spindles and Golgi tendons consistent in weakness of the muscle. PNF contest advice to re-educate the motor units which are absent due to the injury. A array of methods abatement beneath the explanation of PNF, including the corruption of postural reflexes, the use of force to facilitate movement in anemic muscles, the use of aberrant contractions to facilitate agonist beef activity, authority relax, arrangement relax, adroit stabilization, adroit admission and the use of askew movement patterns to facilitate the activation of bi-articular anatomy (Etnyre & Abraham L D, 1987; Hardy & Jones, 1986 Osternig, Robertson, Troxel, & Hansen, 1987).

Tomasz Wolny, Edward Saulicz and RafaÅ‚ Gnat in 2009 conducted a randomized ascendancy abstraction on the adeptness of proprioceptive neuro-muscular abetment in rehabilitation for activities of circadian active in backward post-stroke patients. In this abstraction sixty four achievement patients were recruited from the acoustic rehabilitation centre Capacity for this abstraction were recruited based on some admittance criteria. The patients with blow of sphincter control, blow of mobility, locomotion and advice were included in this abstraction and patients with brand 5 or 6 ‘Repty’ Anatomic lndex calibration were included in this study. Afterwards the application of patients, all the 64 patients were about disconnected into two groups, accumulation A (control group) and accumulation B (experimental group). Accumulation A will accept accepted assay like strengthening, amble training etc. Accumulation B will accept PNF based exercise. A pre and column appraisal of the anatomic cachet of the achievement patients was done application ‘Repty’ Anatomic lndex scale. The assay will be affiliated for 21 canicule for both the groups in the acoustic rehabilitation centre. . The abstracts were analyzed application chi-square test. Chi-square was acclimated to abstraction associations amid the treatments and changes in the archetype measurements. ANOVA was acclimated to analyze the boilerplate changes amid the two groups. The aftereffect of this abstraction showed that PNF-based rehabilitation exercise of backward post-stroke patients decidedly bigger in their ADL anatomic achievement and in locomotion back compared to the ascendancy accumulation advised with accepted therapy.

Kuniyoshi Shimura.A, Tatsuya Kasai. B in 2002 conducted a abstraction on Furnishings of proprioceptive neuromuscular abetment on the admission of autonomous movement and motor evoked potentials in aerial limb anatomy activity. In this abstraction columnist advised the aftereffect of PNF limb positions and aloof limb positions on the admission of autonomous limb movement and motor evoked potentials in aerial limb muscles. In this beginning abstraction the patients were disconnected into two groups, in beginning accumulation 1 they advised the capability of PNF by because the furnishings of limb position changes on the admission of autonomous movement in agreement of electromyographic acknowledgment times. In beginning accumulation 2 they advised the capability of no (neutral limb position) movement by because the aftereffect of limb position changes on the admission of autonomous movement with electromyographic acknowledgment times. Afterwards signing the accord the agreement was conducted on the patients. Two aerial arm positions acclimated in this study, a aloof position (N) and a position facilitating action of the aerial extensor anatomy (PNF). The furnishings of these positions are empiric in the EMG. The accountable could irenic accept the two aerial arm positions application his appropriate (affected) arm by agency of abnormally fabricated arm holders. For anniversary arm position, six blocks of 10 trials were performed. All trials of the first

block and the aboriginal balloon of anniversary of the afterward blocks were afar from the assay to annihilate start-up effects. In addition, a few trials were abandoned because of accessible mistakes in the recording. EMGs were recorded accompanying from three anatomy (Brachioradialis, triceps brachii and deltoid) application 3 cm diameter, bipolar, argent apparent electrodes affiliated to an EMG-unit.

The aftereffect of this abstraction showed that the EMG acquittal adjustment differed amid the two positions. PNF position improves movement adeptness of the collective by inducing changes in the arrangement in which the anatomy are activated. Hence PNF has an able role in the admission of autonomous movement and motor evoked abeyant in aerial limb beef activity.

Pamela Duncan and Lorie Richards et al., in 1998 conducted a abstraction on the aftereffect of Home-Based Exercise Affairs for Individuals with Balmy and Abstinent Stroke. In this randomized controlled pilot study, 20 individuals with balmy to abstinent achievement who had completed astute rehabilitation affairs and those who were 30 to 90 canicule afterwards access of achievement were randomized to a 12-week (first 8-week will be therapist-supervised affairs and the abutting 4-week will be absolute program) rehabilitation program. Afterwards signing the accord form, patients were called based on some admittance belief like (1) 30 to 90 canicule afterwards stroke; (2) basal or moderately broken sensorimotor action (3) ambulant with administering and/or advantageous device; (4) active at home; and (5) active aural 50 afar of the University. The exclusion belief for this abstraction are (1) a medical action that interfered with aftereffect assessments or bound accord in sub acute exercise program, (2) a Mini-Mental State account <18 and (3) acceptant aphasia that interfered with the adeptness to chase a 3-step command.

The participants for this abstraction were called and evaluated by a therapist based on the admittance and exclusion criteria. If the capacity agreed to participate in this study, again the basal appraisal is done afterwards accepting the abreast consent. The severity of the achievement were adjourned application Orpington Prognostic Calibration (Sue-Min Lai and Pamela W. Duncan 1998) and Fugl-Meyer Motor Account (Pamela W Duncan 1982) that includes appraisal of motor action of the arm, aerial acme proprioception, coordination, balance, and 10 cerebral questions. The anatomic assessments are performed application Barthel Basis Activities of Circadian Active (Fricke and Unsworth 1997) Lawton Instrumental Activities of Circadian Active and Medical Outcomes Study-36 Bloom Cachet Measurement (Colleen and John 1992).

Functional assessments of antithesis and amble of the participants were adjourned application 10-Meter Walk, 6-Minute Airing (Kosak and Smith 2005) and Berg Antithesis Calibration (Berg, Wood-Dauphinee and Williams 1995). Aerial acme duke action was evaluated with the Jebsen Assay of Duke Function.The Jebsen is a connected appraisal to admeasurement the time taken to accomplish duke activities. These includes: autograph a abbreviate sentence, axis over 3×5 cards, acrimonious up baby objects, stacking checkers, apish eating, affective abandoned ample cans, and affective abounding cans(Jebsen, Taylor, Trieschmann 1969).

After baseline appraisal the capacity were about assigned into two groups, beginning accumulation and ascendancy group. In beginning groups the PNF exercise were accomplished to the patients on day one as an home exercise and they were asked to abide the aforementioned exercise as an home affairs for eight weeks with three visits to the concrete assay administering every week. The exercise includes advantageous and arresting contest application Proprioceptive Neuromuscular Abetment Patterns and Theraband exercise to the above beef groups of the aerial and lower extremities. Capacity in the ascendancy accumulation accustomed accepted affliction as assigned by the physicians. The capacity of this accumulation were adjourned by the assay assistant.

The demographic abstracts of both the groups were statistically compared application Wilcoxon rank sum tests. The after-effects of this abstraction showed that there is no aberration in the pre and column exercise treatment. There is no change in the aerial acme action and the anatomic bloom cachet in both the beginning accumulation as able-bodied as in ascendancy accumulation afterwards the assay interventions.

Ruth Dickstein, Shraga Hochman, Thomas Pillar, and Rachel Shaham in 1992 conducted a abstraction on Achievement Rehabilitation with Three Exercise Assay Approaches. One hundred and ninety-six hemiplegic patients were about called for this study. All capacity were referred to the concrete assay administering of a geriatric-rehabilitation hospital over a aeon of 18 months were accepted to the study. All patients had a contempo cerebrovascular blow and came for a rehabilitation affairs afterwards an boilerplate break of 16 canicule in a accepted hospital. Sex administering was according with a beggarly age of 70.5 years. Thirteen physiotherapists were enrolled in the abstraction for exercise administering and the capacity were assigned about to anniversary therapist. The abstracts were calm in a abstracted form, which has two parts; aboriginal allotment was acclimated to aggregate the basal advice like age, gender, ancillary afflicted and area of the damaged artery. The additional allotment was acclimated to almanac the capricious data. Anniversary therapist advised their aboriginal bristles patients with accepted method, abutting bristles with PNF adjustment and the aftermost bristles with Bobath method. All patients were advised for bristles canicule a anniversary for six weeks, and anniversary assay sessions were aftermost for 30 to 45 minutes.

The outcomes of anniversary accommodating are abstinent afore the assay and every anniversary thereafter. The anatomic adeptness is abstinent with Barthal index. Beef accent of the complex extremities

was arrested by acquiescent movements of the extremities with the patients in collapsed position. Beef accent was graded application an cardinal calibration composed of bristles points: a) flaccid, b) low, c) normal, d) high, and e) spastic. Ambulant cachet of the accommodating was adjourned and classified with a nominal four class scale: a) accommodating does not walk, b) accommodating walks with an advantageous accessory and person’s help, c) accommodating walks with an advantageous device, and d) accommodating walks independently. The assay was affiliated for 6weeks in both the groups. The abstracts were analyzed application chi-square test. Chi-square was acclimated to abstraction associations amid the treatments and changes in the archetype measurements. The Kruskal-Wallis one-way assay of about-face (ANOVA) was acclimated to analyze the boilerplate changes amid the three groups.

The after-effects of this abstraction showed that there is no cogent aberration in the advance of activities of circadian active and in the walking ability. But there is cogent aberration in the advance of beef accent in PNF accumulation and in Bobath accumulation back compared to the accepted assay group.


The poor affection of the trials advised acutely banned the abstracts that can be drawn. However, it seems that currently there is no evidence, that interventions based on the Proprioceptive Neuro-muscular Abetment (PNF) are added able than alternative approaches. One Abstraction done by Ruth Dickstein on PNF vs. Bobath assured that PNF exercise accustomed in affiliation with Bobath address are added able in convalescent wrist backbone and aerial limb action than giving PNF alone. But the outcomes acclimated in these studies are cardinal appraisement scales, which may not be acute abundant to differentiate the aftereffect of the two techniques. The cardinal of capacity recruited for these studies is actual less. We cannot appear to cessation on the aftereffect of PNF in aerial limb action with these beneath cardinal of studies.

Stroke patients may alter broadly on factors such as concrete impairments, accent impairments, severity of impairments, cerebral impairments, and additionally in the alone personality and acquirements styles. So, we cannot accept that this PNF address is above to all alternative techniques, because we cannot say this address can be acclimated in individuals with achievement and at every date of recovery. For archetype one access may be able in antecedent date of stroke, but the aforementioned access may not be able for abiding achievement patients. Factors such as depression, spatial awareness, cognition, apperception and acoustic blow could additionally accept an appulse on the acknowledgment of a technique.

In best of the studies there is no exact analytic award about the problem, admeasurement of bane and the armpit of lesion. Characteristics of the bane may explain the airheadedness in admiration to the intervention. There is no ideal timing of the interventions, whether the address should be accustomed in the antecedent date or backward date of stroke.

In this assay on the aftereffect of PNF in aerial limb action in stroke, affirmation on the accepted convenance is lacking. Because of the abridgement of affirmation on accepted convenance it is actual difficult to accomplish a conclusion. Affirmation of abutment and assay acclimated in these accessories is not accepted to use in today’s bloom affliction practice. It is appropriate that added studies comparing the aftereffect of PNF with alternative approaches application sensitive, reliable aftereffect measures and with akin sample admeasurement should be done. Therefore it is important that approaching studies analyze the assay and interventions acclimated aural the PNF address to accredit authentic appraisal of the study. No studies on this assay adjourned the adeptness and the capability adequately, so added studies should be done to get an able and optimal access in the rehabilitation of aerial limb action in achievement patients.
