No increase in muscle tone
1
Slight increase in muscle tone,
manifested by a catch and release or
by minimal resistance at the end
range of motion when the part is
moved in flexion or
extension/abduction or adduction,
etc.
1+
Slight increase in muscle tone,
manifested by a catch, followed by
minimal resistance throughout the
remainder (less
than half) of the ROM
2
More marked increase in muscle tone
through most of the ROM, but the
affected part is easily moved
3
Considerable increase in muscle tone,
passive movement is difficult
• Spasticity or muscular hypertonicity is a
- disorder of the central nervous system (CNS) in
which certain muscles continually receive a message to
tighten and contract.
-The nerves leading to those muscles, unable to
regulate themselves (which would provide for normal
muscle tone), permanently and continually "over-fire"
these commands to tighten and contract.
- This causes stiffness or tightness of the muscles
and interferes with gait and movement, and
sometimes speech.

Goals of spasticity management
• To improve function related to the activities of
daily living, mobility, the ease of care by
caregivers, sleep, cosmesis, and overall functional
independence
• To prevent orthopedic deformity, the
development of pressure areas, and the need for
corrective surgery
• To reduce pain
• To allow the stretching of shortened muscles, the
strengthening of antagonistic muscles, and the
appropriate orthotic fit

Physical, Occupational and Speech
Therapy
• Physical and occupational therapy are the mainstays of treating
children with cerebral palsy and other brain injuries.
• Therapists provide range-of-motion exercises to prevent
contractures. The exercises include moving joints to maintain or
improve flexibility, stretching to maintain muscle length,
strengthening, and performing functional movements.
• Therapy also helps maximize the impact of other treatments.
• Speech/language pathologists assess speech and swallowing
problems and work with patients to improve their language
and other skills.
Orthoses
• Orthoses can help to compensate for
weakness and instability.
• Although they typically don’t reduce
spasticity, they may help prevent
complications of spasticity (such as
contractures) or abnormal joint positions.
• Ankle-foot orthoses have been known to
decrease clonus at the ankle as measured by a
computerized gait analysis.
Botulinum Toxin and Phenol
Injections
• Neurolytic blocks (using botulinum toxin or
phenol) can
focally reduce hypertonicity. The blocks can be
used in
children of any age.
• The blocks often control spasticity and its
complications until more aggressive treatments
are appropriate.
• The blocks can be used indefinitely if continued
functional improvements are seen.
Oral Medications
• Oral medications are a systemic, rather than
focal, treatment for spasticity in children.
• Oral medications commonly used in children
are baclofen, diazepam, dantrolene and
tizanidine.
Surgery
• Intrathecal Baclofen Pump Implantation
– baclofen is delivered intrathecally by a catheter
attached to a subcutaneously implanted
computerized pump (spasticity can be markedly
reduced)
– The pump needs refilling every one to three
months and replacing when the battery loses
power (usually after five to seven years)
Orthopaedic Surgery
• used to help correct the secondary problems
that occur with growth in the face of spastic
muscles and poor motion control.
• Those problems include muscle contractures
and bony deformities.
SDR Surgery
• reduces spasticity, primarily in the trunk and legs.
• Surgeons identify dorsal or sensory roots at the L1 to
S1 or S2 levels, then divide them into rootlets.
• The rootlets are then stimulated, and the resulting
motor or reflex responses are monitored by
electromyography and on clinical exam.
• If an abnormal response is seen, the rootlet is cut. The
percentage of rootlets cut varies among patients,
depending on their response to stimulation, but
typically it’s between 25 and 45 percent.
