It is of great challenge for physical therapist to select methods
most efficient for each patient's needs,
Following aspects needs considerations:
* The neuro-physiological basis of each method.
* The biomechanical influencing.
. The nature of pathology and symptoms affecting the patient's
activity.
* The individual characters of each patient.
DEFINITION
O'Sullivan S & Schmitz T (2007). Physical rehabilitation (5" ed). Philadelphia,
F. A. Davis Company.
The term neuromuscular facilitation refers to the facilitation, activation and
inhibition of muscle contraction and motor responses.
FACILITATION TECHNIQUES:
« It refers to the enhanced capacity to initiate a movement response through
increased neuronal activity and altered synaptic potential.
* The stimulus applied may lower the synaptic threshold of the alpha motor
neuron but may not be sufficient to produce an observable movement
response.
* It helps to normalize the muscle tone from flaccid state.
(On the other hand activation refers to the actual production of a movement
response and implies reaching a critical threshold level for neuronal firing.)
DEFINITION
INHIBITION TECHNIQUES:
* It refers to the decreased capacity to initiate a movement response
through altered synaptic potential.
* The synaptic potential is raised, making it more difficult for the neuron
to fire and produce movement.
* To normalize the muscle tone from hypertonic or spastic state.
( The combination of spinal and supraspinal inputs acting on the alpha
motor neuron (final common pathway) will determine whether a muscle
response is facilitated, activated or inhibited.)
THEORETICAL BASIS
Roods approach-As a therapeutic technique presented originally by Margaret
Rood to facilitate and inhibit movement responses.
Reflex Theory
* The basic unit of motor control are reflexes
+ Reflexes > purposeful movement.
+ Damage to the CNS results to re-emergence of and inability to control the
reflexes.
THEORETICAL BASIS
Hierarchical Theory
* Motor control is hierarchically arranged
+ CNS structures involved with movement can be grouped into HIGHER,
MIDDLE, and LOWER levels.
+ Higher centers regulate and control the middle and lower centers.
+ Damage to the CNS results to disruption of the normal coordinated function of
these levels.
PRINCIPLE OF TECHNIQUES
RECIPROCAL INHIBITION
+ Aka innervation, mobility
+ Phasic or quick type of movement
+ Contraction of the agonist while antagonist relaxes
+ Serves a protective function
CO-CONTRACTION
* Aka co-innervation, stability
* Tonic or static type of movement
* Simultaneous contraction of the agonist and antagonist
+ Foundation for postural control
PRINCIPLE OF TECHNIQUES
HEAVY WORK
* Aka mobility superimposed on stability
* Proximal muscles contract and move while distal segments are
fixed
SKILL
* Aka mobility and stability
* Proximal segments are stabilized while distal segments move
PRINCIPLE OF TECHNIQUES
* A fast, brief stimulus produces a large synchronous movement. F
+ A fast, repetitive stimulus produces a maintained response. A
* Slow, rhythmical, repetitive sensory input deactivates the body. I

GENERAL GUIDELINES TO BE
CONSIDERED
* Facilitative techniques (additive). Example, several inputs applied
simultaneously, such as a quick stretch, resistance and verbal cues, are
commonly combined during practice of a PNF.(SPATIAL
SUMMATION)
* Repeated stimuli (e.g. tapping) may also produce the desired motor
response owing to TEMPORAL SUMMATION.
GENERAL GUIDELINES TO BE
CONSIDERED
* Sensory receptors based on adaptation: Slow- and Fast- adapting.
* Fast- adapting, phasic receptors such as touch receptors and phasic la
muscle spindle endings are effective initiating and shaping dynamic
movements.
* Slow- adapting, tonic receptors such as joint receptors, GTOs, and
static 2 muscle spindle endings are effective in monitoring and
regulating postural responses.
GENERAL GUIDELINES TO BE
CONSIDERED
* The intensity, duration and frequency of stimulation need to be
adjusted to meet individual patients needs.
* Unpredicted responses = Inappropriate application of techniques. For
example, stretch applied to a spastic muscle may increase spasticity
and negatively affect voluntary movement.
* Facilitation techniques are not appropriate for patients who
demonstrate adequate voluntary control.

+ Effective in initiating a generalized movement response, to elicit arousal, contraindicated to
agitated patients or when ANS is unstable.
Low threshold response, accommodates rapidly.
+ Can be used to initially mobilize patients with low response levels(eg., the patients with TBI who
is minimally responsive).
Findings indicate that light touch could be beneficial in postural control for individuals with hemi-
paretic stroke,

CUTANEOUS FACILITATION
FAST BRUSHING (receptors: tactile receptors, ANS sympathetic division)
+ Application can be manually or by using battery-operated brush.
* Skin overlying muscle can facilitate it and enhances static holding postural
extensors and will have immediate and long latency responses.
+ Used to facilitate inhibited muscles below the skin.
+ Anterior primary rami: excitatory effect is local and mainly to superficial
muscles,
+ Posterior primary rami: effect is excitatory for deep back muscles.
* The area to be brushed is very specific to dermatomes and myotomes.
+ Brush for at least 3 seconds , and wait for response until 20-30 minutes, where
nerve pathways are not active due to disuse or inhibition.
+ Positive effect on H-reflex.
THERMAL FACILITATION- BRIEF
ICING
* A ICING (FAST ICING); stimulates A fibers causing reflex withdrawal response in superficial
muscles. Patients with hypotonia, muscles are in state of relaxation causes alertness in them.
+ CICING: stimulates non-specific € fibers that maintain postural response.
+ Applied according to dermatomes.
* Contraindications: avoid to patients with h/o cardiovascular problems.
* Do not apply over the neck, it will cause low BP.
* Ice applied over lips and tongue facilitates sucking, swallowing and speech.
R-Abd El-Maksoud GM, Sharaf MA, Rezk-Allah SS. Efficacy of cold therapy on spasticity and hand
function in children with cerebral palsy. Journal of Advanced Research, 2011 Oct 1:2(4):319-25,
It can be concluded that cold therapy in conjunction with conventional physical and occupational
therapy significantly reduced spasticity, increased ROM and improved hand function in children with
spastic CP.
PROPRIOCEPTIVE FACILITATION
HEAVY JOINT COMPRESSION
+ Joint awareness will improve by joint compression which will enhance motor control.
: Receplors in joints and muscles are involved in awareness of joint position and movement
which are simulated by joint compression.
. Compression of the joint surfaces facilitates posture extensors which are needed to
stabilize the body. Compression greater than that applied by body weight is thought to
facilitate co-contraction at the joint.
* The application may be manually and/or by using weight bearing postures.

individ als with strokes. Physica ceupational Therapy In Geriatrics. 1993 Jan
Paper concludes that splints have been effectively used to reduce tone, facilitate muscle
activity around a joint, increase sensory input, control edema, and reduce pain.

QUICK STRETCH
* Receptor: muscle spindle endings, detecting length and velocity changes.
+ Stimulus: quick stretch or tapping over muscle belly or tendon.
* Response: activates agonist(intrafusal & extrafusal) to contract-stretch reflex,
reciprocal innervation effect will inhibit the antagonist; activates synergists.
* Optimally applied in the lengthened range. A low-threshold response, relatively
short-lived, can add resistance to maintain contraction.

There is a wide diversity in studies investigating the effects of stretching on
spasticity, and the available evidence on its clinical benefit is overall inconclusive.
PROPRIOCEPTIVE FACILITATION
INTRINSIC STRETCH
* Activates the proprioceptors in selected muscles and imply the
principle of reciprocal innervation.
+ It promotes stability of the scapulohumeral region, bearing more
weight on the ulnar side of the hands and promoting resistive grasp.
* Joint compression to elbow with stretch to wrist extensors in
quadruped position.
PROPRIOCEPTIVE FACILITATION
SECONDARY ENDING STRETCH
* Combination of resistance and stretch to facilitate developmental
patterns. Once a muscle is put on a full stretch, secondary nerve
endings which is facilitatory to the flexors and inhibitory to the
extensors.
PROPRIOCEPTIVE FACILITATION
STRETCH PRESSURE
* Mechanical stresses in contracting muscles in terms of stretch and
pressure led to activation of glucose metabolism and protein synthesis.
Hence causes muscular hypertrophy.
* Here comes the combine role of GTO(muscle tension and contraction)
and muscle spindles.(change in length of muscle fibers)
PROPRIOCEPTIVE FACILITATION
RESISTANCE
* Receptors: muscle spindles
* Stimulus: resistance given manually or with body weight or gravity or
mechanical weights
* Resistance needs to be graded dependent on the patient response and
goal; additional recruitment and overflow may be counterproductive to
movement goal,
PROPRIOCEPTIVE FACILITATION
TAPPING
* Stimulus: repeated quick stretch over tendon or muscle belly
* Response: activates agonist(intrafusal & extrafusal) to contract-stretch
reflex
* Tapping over muscle belly produces a weaker response than over the
tendon.
* Tapping over a muscle is used to enhance holding in a weight bearing
position.
PROPRIOCEPTIVE FACILITATION
VESTIBULAR STIMULATION(FAST)
* Receptor: semicircular canals in ears
* Stimulus: fast or irregular movement with acceleration and deceleration
component, such as spinning, use of a scooter board, fast rolling
+ Response: facilitates general muscle tone and promotes postural responses to
movement
+ Useful for patients with hypotonia (CP, downs syndrome); used to promote
sensory integration. Also in patients with sensory integrative
dyehunetron(hyperastive child ADHD); patients with bradykinesia (PD).
