Learning Objectives…
At the end of the lecture, the students should be
able to:
• Discuss the theoretical basis of the
neurodevelopmental approaches
• Discuss the concepts and principles underlying
the Bobath approach
• Discuss the concepts and principles underlying
the Brunnstrom approach
Sensorimotor Approaches
•
•
•
•
Bobath approach
Brunnstrom’s movement therapy
Rood approach
Proprioceptive neuromuscular facilitation
Theoretical basis…
•
•
•
•
Neurodevelopmental model
Reflex theory
Hierarchical theory
Systems approach
Neurodevelopmental Model
• motor control and its production refers to
two systems of output: the open loop
(voluntary control ) and the closed loop
(postural control) mechanisms
(Keshner, , 1981)
Open-loop system…
• commands sequences of movement that
are centrally stored in the nervous system
and that serve the functions of mobility in
the production of isolated joint and limb
motions
(Keshner, , 1981)
Closed-loop system…
• Dependent upon afferent feedback for
the elicitation of its automatic movements
that serve as the principle motility or
stability of the organism
• prerequisite for the development of
normal movement behaviors
• arise from patterns of coordination
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
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
Systems approach
• suggests that the CNS does not operate in a
strictly descending manner
• no higher levels with which to control the
operation of the lower levels
• there is a mutable relationship between the
various levels so that each level will alternate
between command and subordinate roles in
relation to the other levels.
(Keshner, , 1981)
Bobath Approach
Concepts and Principles
History…
• Developed by Dr. Karel Bobath, a
neuropsychiatrist, and Mrs. Berta Bobath, a
physical therapist
• 1943 – while working with children with
cerebral palsy
Original theoretical framework…
• Based on the works of Jackson,
Sherrington, and Magnus
 who described nervous system as
HIERARCHICAL in nature
• Model
 Higher brain centers exerted control over
lower-level centers
 Eg. The cerebral cortex control supercedes that
of the brainstem
Original theoretical framework…
• Hypothesis
 A neurologic insult will lead to a release of
the lower-level centers from higher-level
center inhibitory control, resulting in
stereotypical postures, primitive movement
patterns and predominant reflex activity
Adult hemiplegia..
• Treatment approach was later on expanded
to include the rehabilitation of adults with
motor problems, particularly CVA
• Main problem: the abnormal coordination
of movement patterns combined with
abnormal postural tonus (Bernstein, 1967)
• Secondary problem: muscle strength and
muscle activity
Bobath concept…
• Is a living concept, it is not static
 It has undergone changes in its theoretical
base to accommodate developments in the
fields of neurophysiology, biomechanics, and
typical development
• Holistic approach
 It involves the whole patient, his sensory,
perceptual and adaptive behaviour, and motor
problems
Traditional View
• Principles of treatment
–
–
–
–
Normalize muscle tone
Inhibit primitive reflexes
Facilitate normal postural reactions
Treatment should be developmental
• Techniques
– Handling
– Weight bearing over the affected limb
– Utilize positions that allow use of the
affected limbs
– Avoidance of sensory input that affect muscle
tone
Previously…
• The control of movement was thought to be
dependent on the normal postural reflex
mechanism
 E.g. utilizing righting reactions and
equilibrium reactions in association with
normal postural tone
Systems Theory
Hierarchical Theory
Reconstruction of
the
NDT approach
Premise
• Different parts of the CNS influence one
another
• Nervous system is capable of initiating,
anticipating, and controlling movements
– feedforward and feedback mechanisms
• CNS has the ability to shape and/or renew
itself in response to practiced activities:
neuroplasticity
Evidence on neuroplasticity
(Fisher, BE and Sullivan, KJ, 2001)
• Neuroplasticity can occur on the lesioned side of
the cerebral cortex following CVA when
provided appropriate practice in using involved
side
• Rehabilitation strategies should promote
recovery rather than compensation
• Techniques should incorporate the following:
– Active participation in motor skill learning
– Specific skills training and strengthening directed
to the involved limbs
– Intense, task-specific practice that optimizes the
sensorimotor experience
Basic premises…
• Sensations of movements are learned, not
movements per se
• Basic postural and movement patterns are
learned that are later elaborated on to
become functional skills
Problems in the adult patient with
stroke
•
•
•
•
Abnormal tone
Loss of postural control
Abnormal coordination
Abnormal functional performance
Goals…
• Decrease the influence of spasticity and
abnormal coordination
• Improve control of the involved trunk, arm
and leg
• Retain normal, functional patterns of
movement in the adult stroke patient
Principles of treatment:
Adult hemiplegia
• Treatment should avoid movements and
activities that increase muscle tone or produce
abnormal reflex patterns in the involved side
• Treatment should be directed toward the
development of normal patterns of posture and
movement (movement patterns are not based on
the developmental sequence but on patterns
important for function)
Principles of treatment:
Adult hemiplegia
• The hemiplegic side should be incorporated
into all treatment activities to reestablish
symmetry and increased functional use
• Treatment should produce a change in the
quality of movement and functional
performance of the involved side
Principles of treatment:
Adult hemiplegia
•
•
•
•
Individualize functional outcomes
Emphasize motor control
Increase active use of the involved side
Provide practice to improve motor
performance that lead to motor learning
• Teach 24-hour management to increase
retention and carryover
• Use an interdisciplinary approach to
intervention
Stages of hemiplegia and the
Bobath Approach
• Initial Flaccid Stage
 tx focus on positioning and movement in bed
to avoid the typical postural patterns of
hemiplegia
• Stage of Spasticity
 tx is a continuation of the previous stage with
the goal of breaking down the total patterns by
developing control of the intermediate joints
Stages of hemiplegia and the
Bobath Approach
• Stage of Relative Recovery
 tx aims at improving the quality of gait and
the use of the affected hand
Principles of treatment: children
with cerebral palsy
• Treat the child as a whole
• Basis for intervention is normal movement
and their interrelationships
• Treatment incorporates facilitation and
inhibition using key points of control
 abnormal tone is always inhibited
 normal responses, once elicited, are always
repeated
What are key points of control
(KPC)?
• Parts of the body where the therapist can most
effectively control and change patterns of
posture and movement in other body parts
– Proximal: spine, sternum, shoulder/scapula,
pelvis/hip
– Distal: jaw, elbow, wrist, knee, base of the
thumb, ankle, big toe
– Head may be a proximal or distal KPC
• use KPC that allow full pattern to be broken
during handling
Facilitation-Inhibition
• Facilitation
 is a mean by which movement is made easy,
made possible, and made necessary
• Inhibition
 involves decreasing the use of pathological
movements and the effects of tonal dysfunctions
on movement
• Facilitation and inhibition may be used
simultaneouly and may be applied throughout
the session
What is handling?
Manner of controlling the patient through
tone influencing patterns
•
•
Normal patterns of activity used to modify
abnormal patterns of posture and movement
o Total TIPs: whole body is controlled in a
reversal of the abnormal pattern
o Partial TIPs: some body parts remain
free to move
TIPs are utilized via KPCs
Law of Shunting
• “ at any moment during the movement or a
postural change, the CNS mirrors or reflects
faithfully, the state of the body
musculature”
• Therefore, it is the body musculature which
guides and directs the CNS
• Thus, tone inhibiting patterns are used to
give the CNS the sensation of normal
movements
Principles of treatment: children
with cerebral palsy
• Child must be active during treatment to
achieve functional goals
 Voluntary control of normal responses is
encouraged
• Treatment and evaluation are ongoing
• Treatment if functionally-oriented
Principles of treatment: children
with cerebral palsy
• NDT is appropriate for persons with
sensorimotor dysfunction regardless of
age and cognition
• Non-professionals can be an active
participant in treatment
Treatment methods…
• Modify sensory input through handling,
positioning reflex inhibiting postures and
use of key points of control
• Facilitate automatic reactions
• Normal movement patterns are integrated
into developing nervous system
OLD THEORY
Hierarchical brain organization (Reflex
model)
NEW THEORY
Systems Model
Normal postural reflex mechanism as the Postural control is learned together with
basis of normal movement
the skill; feedback and feedforward
mechanisms needed for efficient
movement control
Static postures and positions used for
treatment
Client is an active participant in the
session
Progressing the client through normal
developmental milestones
Developmental milestones serve as
guidelines but should not be strictly
adhered to
Development of control proceeds in a
cephalocaudal direction
Control of movement develops in
proximal to distal or distal to proximal
directions
Work on components of motions which
the child will then apply to function
Client must work on functional tasks to
learn the skill
Evidence
The Effectiveness of the Bobath
Concept in Stroke Rehabilitation
• Boudewijn, K. et al. (2009)
• Stroke. 2009;40:e89.
• 16 studies involving 813 patients with stroke were
included for further analysis.
• There was no evidence of superiority of Bobath on
sensorimotor control of upper and lower limb, dexterity,
mobility, activities of daily living, health-related quality
of life, and cost-effectiveness.
• Only limited evidence was found for balance control in
favor of Bobath.
Brunnstrom’s Movement
Therapy
Concepts and Principles
History…
• Developed by Signe Brunnstrom, a physical
therapist from Sweden
• Theoretical foundations:




Sherrington
Magnus
Jackson
Twitchell
Premise
 When
the CNS is injured, as in CVA, an
individual goes through an “evolution in
reverse”
– Movement becomes primitive,
reflexive, and automatic
 Changes
in tone and the presence of
reflexes are considered part of the normal
process of recovery
Principles of treatment
 Facilitate
the patient’s progress throughout
the recovery stages
 Use
of postural and attitudinal reflexes to
increase and decrease tone of muscles
 Stimulation
of skin over the muscle
produces contraction
 Resistance
facilitates contraction
Basic limb synergies
• Mass movement patterns in response to
stimulus or voluntary effort or both
– Gross flexor movement (flexor synergy)
– Gross extensor movement (extensor synergy)
– Combination of the strongest components of the
synergies (mixed synergy)
• Appear during the early spastic period of
recovery
Important! (Limb Synergies)
• Muscles are neurophysiologically linked
and cannot act alone or perform all of their
functions
• If one muscle in the synergy is activated,
each muscle in the synergy responds
partially or completely
• Patient CANNOT perform isolated
movements when bound by these synergies

Associated reactions
• Investigation by Walshe (1923)
– Associated reactions are released postural
reactions deprived of voluntary control
• Investigation by Simons (1923)
– Position of the head has a marked influence on
the outcome of the associated rections
– Limb reactions evoked closely resemble tonic
neck reflexes
• Observations by Brunnstrom (1951,1952)
– UE: movements employed elicited the same
reactions in the affected limb
– LE: movements employed elicited opposite
reactions in the affected limb
Associated reactions
• Observations by Brunnstrom
(1951, 1952)
– may be evoked in a limb that is essentially flaccid,
although latent spasticity may be present
– may occur in the affected limb under a variety of
condition: in the presence of spasticity, when a
degree of voluntary control has been achieved, and
after spasticity has subsided
– may be present years after the onset of hemiplegia
Associated Reactions
• Observations by Brunnstrom (1951,1952)
– repeated stimuli may be required to evoke a
response
– tension in the muscles of the affected limb
decrease rapidly after cessation of stimulus that
evoked the associate directions
– attitudinal reflexes influence the outcome of
associated reactions
Associated reactions
• Homolateral Limb Synkinesis
– The response of one extremity to stimulus
will elicit the same response in its ipsilateral
extremity
• Raimiste’s Phenomenon
– Resisted abduction or adduction of the
sound limb evokes a similar response in the
affected limb
Associated reactions
• Yawning
– Flexor synergy is elicited during initiation of
yawn
• Coughing and Sneezing
– Evoke sudden muscular contractions of short
duration
Hand reactions
• Steps to restoration of hand function
(Twitchell, 1951)
1. Tendon reflexes return and become
hyperactive
2. Spasticity develops; resistance to passive
motion is felt
3. Voluntary finger flexion occurs, if facilitated
by proprioceptive stimuli
Hand reactions
4. Proprioceptive traction response can be
elicited
–
–
Aka proximal traction response
Stretch of flexors of one of the joints of the
upper limb facilitates a contraction of the flexor
muscles of other joints of the same limb thus
producing total limb shortening
5. Control of hand without proprioceptive
stimuli begins
Hand reactions
6. Grasp is reinforced by tactile stimulus on
the palm of the hand; spasticity declines
7. True grasp reflex can be elicited; spasticity
further declines
–
Elicited by disctally moving deep pressure over
certain areas of the palm and digits
»
»
Catching phase: weak contraction of flexors and
adductors upon stimulus
Holding phase: proceeds when traction is done on
muscles activated in the catching phase
Other hand reactions
• Instinctive Grasp Reaction
– Stationary contact with the palm of the hand results
to closure of the hand
• Instinctive Avoiding Reaction
– With the arm elevated in a forward-upward
direction, the fingers and thumb hyperextend;
stroking the palm in a distal direction exaggerates
the posture
• Soque’s Finger Phenomenon
– Elevation of the hemiplegic arm beyond the
horizontal results to estension and abduction of the
fingers
Recovery stages in hemiplegia
STAGE
CHARACTERISTICS
Stage 1 •Period of flaccidity
•Neither reflex nor voluntary movements are present
Stage 2 •Basic limb synergies may appear as associated reactions
•Spasticity begins mostly evident in strong components
(flexor synergy appear prior to extensor synergy)
•Minimal voluntary movement responses may be present
Stage 3 •Patient starts to gain voluntary control over movement
synergies
•Spasticity reaches its peak
•Semi-voluntary stage as individual is able to initiate
movement but unable to control it
STAGE
CHARACTERISTICS
Stage 4
•Some movement combinations outside the path of
basic limb synergy patterns are mastered
•Spasticity begins to decline
Stage
5
•More difficult combinations are mastered
•Spasticity continues to decline
•Individual joint movement becomes possible
•Coordination approaches normalcy
•Spasticity disappears: individual is more capable of
full movement patterns
Stage
6
Stage
7
Normal motor functions are restored
Treatment Principles
1. Treatment progress developmentally
2. When no motion exists, movement is
facilitated using reflexes, associated
reactions, proprioceptive facilitation and or
exteroceptive facilitation to develop
muscle tension in preparation for voluntary
movement
Treatment Principles
3. Resistance (proprioceptive stimulus)
promotes a spread of impulses to produce a
patterned response while tactile stimulation
facilitates only the muscle related to the
stimulated area
Treatment Principles
4. When voluntary effort produces or
contribute to a response, patient is asked to
hold the contraction (isometric). If
successful, an eccentric (contracted
lengthening) is performed and finally a
concentric (shortening) contraction is done.
Treatment Principles
5. Facilitation is reduced or dropped out as
quickly as the patient shows evidence of
volitional control.
6. No primitive reflexes, including associated
reactions, are used beyond Stage 3.
7. Correct movement once elicited is repeated
