2. Definition: Cerebral Palsy
Defined as a persistent but not unchanging disorder
of posture and movement, caused by damage to the
developing nervous system, before or during birth or
in the early months of infancy
(World commission for Cerebral Palsy,1988)
3. Definition: Spasticity
Defined as a velocity dependent increase in
resistance to passive stretch of a muscle,
with exaggerated tendon reflexes
(Lance,1990; Parziale et al., 1993)
4. SPASTICITY IN CP
Altered muscle tone is one of the earliest signs of
cerebral palsy (Binder H. Eng.GD 1989)
The nature of the movement disorder in spastic cp
is a combination of hyper tonus, impaired postural
control and equilibrium reactions, persistent
primitive reflexes, upper extremity flexor and lower
extremity extensor synergies and associated
weakness (Winters et al1987)
5. Cont..
Spasticity may coexist with other movement
disorders such as athetosis, chorea, or
dystonia
These neurologic abnormalities may lead to
muscle shortening, joint capsule tightness
and osseous deformities (Vinken PJ & Bruyn)
8. 1) EXAGGERATED SEGMENTAL REFLEXES
Exact mechanism is uncertain
The pathological basis of spasticity is the
abnormal enhancement of spinal stretch
reflexes
They could be enhanced by increased
muscle spindle activity or increased
excitability of central synapses involved in
the reflex arc.
9. 2) EXAGGERATED SUPRA SEGMENTAL
REFLEXES
Lesions at level of brain stem and above,
then supra segmental reflexes through the
spinal cord and brain stem became
hyperactive (e.g., tonic neck and vestibular
reflexes)
10. 3) ABNORMAL VOLUNTARY CONTROL
Imbalance in antagonist – agonist voluntary
Control
4) RELEASE REFLEX PHENOMENON
Hyperactive Excitatory neuronal firing
11. 5) DECORTICATE & DECEREBRATE RIGIDITY
Decorticate: Upper limb flexed and lower limb
Extended
Lesions above superior colliculus lead to
decorticate rigidity
Decerebrate: Full Extension Upper and lower
limbs
Lesions below superior colliculus may lead to
de cerebrate rigidity
12. Direct and Indirect Consequences of
Spasticity:
Increased Tone
Decreased Range of Motion
Involuntary Movements
Increased Autonomic Reflexes
Exaggerated Reflexes
Muscle Weakness
Balance Problems
13. Cont…
Abnormal Bone Stress
Contracture
Pain
Sleep Dysfunction
Patient Care (hygiene, transportation)
Bowel and Bladder Dysfunction
Respiratory Dysfunction
16. Modified Ashworth scale
0 = No increase in muscle tone
1 = Slight increase in muscle tone (catch or min resistance at end
range)
1+ = Slight increase in muscle resistance throughout the range.
2 = Moderate increase in muscle tone throughout ROM, PROM is
easy
3 = Marked increase in muscle tone throughout ROM, PROM is
difficult
4 = Marked increase in muscle tone, affected part is rigid
17. Oswestry Scale
It is based on clinical observation and is
graded from 0 to 5( No, Mild,
Moderate,Severe, Very Severe and solely
severe)
18. Spasm Frequency Scale
How many spasms in the last 24 hours in the
affected extremity?
0 = no spasms
1 = 1 / day
2 = 1-5/ day
3 = 5-9 / day
4 = >10/day
19. Adductor Tone Rating
0 = no increase in muscle tone
1 = increased tone, hips easily abducted 45
degrees by one person
2 = hips abducted 45 degrees by on person
with mild effort
3 = hips abducted 45 degrees by one person
with moderate effort
4 = two people are required to abduct the hips
45 degrees
20. Tardieu scale
A scale depending upon the responses of
each muscle to both high and low speed After
ranging a joint slowly and then quickly, the
spasticity is assigned one of the following
scores
21. Cont.. Tardieu scale
0 No resistance throughout the course of the passive movement.
1 Slight resistance throughout the course of the passive
movement with no clear catch at a precise angle.
2 Clear catch at a precise angle, interrupting the passive
movement, followed by a release.
3 Fatiguable clonus, less than 10 seconds when maintaining the
pressure, appearing at a precise angle.
4 Unfatiguable clonus, more than 10 seconds when maintaining
the pressure, at a precise angle
22. Gait Analysis
A test based on timed 10 m walks during
which step are counted has been shown to
be of use ( Collen et al, 1990)
Parameters are Stride length, step length and
cadence can be measured
Video recording( Still man, 1991)

23. Others..
ROM tests: Helps to find tonal changes and
severity of tightness
EMG Studies… Pendular tests
Tendon reflex
Babinski Sign
25. Stepped Care
Stepped Care for spasticity begins with conservative
methods that carry fewest side effects and progress
to aggressive treatments with the most side effects.
First any remedial sources of nociception should be
eliminated. UTI, BOWEL IMPACTION, Pressure
sores, fractures, paronychia etc may increase
spasticity and hypertonus
26. Second Patient education should be
provided. Education allows patients to
minimize adverse effects and to function
despite spasticity
27.
28. MOVEMENT & HANDLING
The use of manual handling techniques is
one of the principle means available to the
neurological physiotherapist in the physical
management of spasticity
29. MAINTANENCE OF SOFT TISSUE
LENGTH
1) ACTIVE & PASSIVE ROM EXERCISES
Without the full range of motion, peripheral changes cause
muscle imbalance and this compounds any central motor
dysfunction (Ada & Canning, 1990; Carr & Shephard,1995)
This can be achieved by passive stretching of tight structures or
any active exercises
Daily ROM & Static muscle stretch prevents contracture &
capsule tightness and can reduce stretch reflex hyperactivity and
improve motor control (Odeen I. Scand. J. Rehabil. Med, 1981)
30. 2) WEIGHT BEARING EXERCISES
Standing is an excellent way of maintaining length in soft tissues
Standing is effective in altering tone via. The vestibular system,
which is a major source of excitatory influence to extensor
muscles, whist reciprocally inhibiting flexor muscles (Markhern,
1987; Brown, 1994)
It is another form of static stretch and it can reverse early
contracture and may reduce stretch reflex excitability (Richards CL
et al., Scand. J. Rehab. Med, 1991)
Back slabs or Standing frames may be used to assist Standing
(Davies, 1994)
31.
32. 3) POSITIONING
Various body or head positions can be used minimize facilitation
that is contributing to hyper tonus and to maximize facilitation to
muscles that have reduced voluntary recruitment (Stejskal L, Am.
J. Physic. Med.. 1979)
In Children with Cerebral Palsy, Lumbar extensor muscle activity
can be altered by adjusting head position and seat and back
angles of seating systems (Nwabhi OM et al., Dev. Med. Child.
Neurology 1983)
33.
34.
35. 4) MODULATION OF MUSCLE TONE
Movement and alteration of the alignment of
particular parts of the body can influence
muscle tone in other areas
For Example, the rotational element is
extremely important and is emphasized in the
approaches like PNF (Voss et al, 1985) & Bobath
(1990)
36. HANDLING TECHNIQUES
According to Mary Lynch,
For Spasticity,
Speed: Slow
Range: Full
Repetition: Yes
Voice: Quiet, Minimal
Other: Longitudinal traction
38. Different types of splinting were described
and reviewed by Edwards & Charlton (1996)
39. Prophylactic Splinting:
It is appropriate for patients who need more
than positioning and assisted movements to
maintain joint range (Conine et al., 1990)
For example, prophylactic splinting can take the
form of Plaster boots for Achilles tendon or
plaster cylinders for limb to prevent tightness or
contractures
40. Corrective Splinting/ Serial Casting
Corrective splinting is used to increase ROM in
the presence of contracture
For example, Serial Casting for elbow
contracture which is helpful in slowly correcting
contracted joints
41.
42. Dynamic Splinting
Dynamic splinting aims to facilitate recovery
and assist stability for improved function
For example, In children with CP, AFO’s with
tone reducing features have been used to
inhibit tonic postures of the foot (Hylton N.,
1990)
44. ES.. Cont..
Vang et al, (1995) found electrical stimulation
resulted in a measurable reduction in
spasticity in upper limb
O’Daniel & Krapfl, 1989 reported that the
use of ES increases the effectiveness of
stretching spastic muscles by reciprocal
inhibition
ES at nearly all levels of the nervous system
relieves spasticity ( Stefanovska. A, 1991)
45. ES.. Cont..
Shindo (1987), has reported a reduction of
spasticity by clinical evaluation, lasting 8 to
72 hours after each session of FES.
Stefanovska (1988) measured decreased
tone and increased voluntary strength in
ankle plantarflexors after peroneal nerve
stimulation for 1 year
46. THERMAL TREATMENTS
Cryotherapy:
Ice can be used as an adjunct to other treatment
methods or as a means of controlling tone in a
specific area
Muscle cooling reduces phasic stretch reflex
activity and clonus (Hartviksen. K, 1962; Giebler KB, 1990)
Slow Icing reduces spasticity (Roods Approach)
Ice can be used with static stretch to overcome
hyperactive stretch reflexes (Giebler KB, 1990)
47. Apply warm water soaks to spastic muscles
or have child sit or lie in warm water
48. HYDROTHERAPY
Pool therapy can be used a adjunct
management for cerebral palsied Children
It helps in stretching large muscle groups & to
help movements in trunk.
49. BIO FEEDBACK
The effectiveness of EMG biofeedback machines in
the treatment of increased muscle tone is yet
unproven (Moreland & Thompson, 1994)
Bio feedback using either EMG or Joint position
sensors and providing auditory or Visual feedback,
has reduced spasticity in patients with preservation
of voluntary motor control (Neilson et al., J. Neurol. Neuro Surg.
Psychiatry, 1982)
It can provide the patient with useful feedback
between therapy sessions
51. VESTIBULAR STIMULATION
All static positions and or movement patterns
facilitate the vestibular system which in turn has
effects over muscle tone (Anne G. Fisher et al..)
Various researches proves vestibular stimulation as
a therapeutic modality in managing abnormalities of
muscle tone. (Weeks ZR, Am. J. Occupational therapy, 1979)
Vestibular stimulation has more impact on the
development of Cerebral Palsied or Mentally
retarded Children than a normal, at risk or
premature infants (Ottenbacher KJ et al., Clinical Paediatrics, 1983)
58. HIPPOTHERAPY
Hippotherapy is a physical, occupational and
speech therapy treatment strategy that utilizes
equine movement (The American hippo therapy Association)
Benda W et al 2003, reported improvements in
muscle symmetry in Children with CP after equine
assisted therapy (The Journal of Complimentary
Medicines, 2003)
Casady R et al reports positive outcome in 10 CP
Children after having hippotherapy
59.
60. Suit therapy
Suit therapy is often used as part of a
comprehensive program of intensive physiotherapy
of 5–7 hours a day for four weeks (UCP, 1999).
This therapy is based on a suit originally designed
by the Russians for use by cosmonauts in space to
minimize the effects of weightlessness. The idea is
to move body parts against a resistance, thus
improving muscle strength.
61. Through placement of the elastic cords, selected
muscle groups can be exercised as the patient
moves limbs; thus, suit therapy is a form of
controlled exercise against a resistance. It is also
claimed that the suit improves coordination.
The suit consists of a cap, a vest, shorts, knee pads,
and shoes. An attached series of elastic cords
provides compression to the body’s joints and
resistance to muscles when movement occurs.
