A MEDLINE SURVEY ON BOTULINUM THERAPY IN CP |
N.B. We at UDAAN rarely now go in for Botox or Phenol Nerve Block in relieving spasticity in CP. The effect of these injections are magical: the child starts walking near normally within 5 minutes to a day. The doctor is happy, the parents are happy, the child is happy. In all this happiness, intensive Standard Therapy is given the go-by. Result: back to the pavilion within a year and Rs.15000 + (US $ 350 or more) gone down the drain. Last revised January 21, 2007.

TITLE - Treatment of cerebral palsy with
botulinum toxin: evaluation with gross motor function measure.
ABSTRACT - The objective of this study was
to investigate the effects of botulinum toxin A (BTA) injection in reducing
muscular spasticity and improving locomotor function in children with
cerebral palsy. Thirty-eight children with spastic cerebral palsy who were
undergoing regular physical therapy were enrolled. Twenty-eight of these
received BTA injection at the hip adductors and/or gastrocnemius, while the
other 10, whose parents refused the BTA treatment protocol, served as the
comparison group. The main outcome measures were:improvements in the
severity of spasticity, walking distance,gross motor function (as assessed
with the Gross Motor Function Measure, GMFM), and gait pattern (as assessed
with the Physician Rating Scale, PRS), all measured 6 and 12 weeks after the
start of BTA treatment. The severity of spasticity and walking distance at
baseline did not differ significantly between the two groups. However, the
severity of spasticity improved markedly in the BTA group,from 2.7 to 1.5
(Modified Ashworth Scale) at the hip adductor,and from 2.9 to 1.9 at the
gastrocnemius at the 6-week follow-up. The walking distance improved from
46.17 m to 55.32 m at the 6-week follow-up, and to 66.6 m at the 12-week
follow-up in the BTA group. Marked improvements in the quality of
several gross motor functions were also noted in the BTA group. The
improvements in spasticity,walking distance, and gross motor function were
significantly greater in the BTA group than in the comparison group. The
improvements in gait pattern did not differ significantly between the BTA
and comparison groups. The findings of this study show BTA injection to be
an effective treatment for reducing spasticity and improving gross motor
function in children with spastic cerebral palsy. GMFM provides objective
evidence regarding functional improvement after treatment in this patient
population.

TITLE - Use of botulinum toxin injection in
17 children with spastic cerebral palsy.
ABSTRACT - The use of botulinum toxin was
studied in 17 children with spastic cerebral palsy to determine its efficacy
and tolerability.Eleven ambulatory and 6 nonambulatory patients were
included.All children were undergoing a physiotherapy program with
monitoring of their baseline states for 3 months before botulinum toxin
injection. The effect was evident within 72 hours. The peak effect was
noticed by 1 to 2 weeks in the majority; the effect lasted
for 3 to 10 months. All children experienced decreased spasticity
scores. Their functional status improved, with three nonambulatory children
becoming ambulatory with assistance and five children with assisted
ambulation becoming more independently ambulatory.Measurement of joint
motion showed improvement in the range of motion as compared with baseline.
Video analysis of the functional state in the nonambulatory or gait in the
ambulatory children revealed improvement in all. The functional status of
rising from the sitting position or standing demonstrated improvement. None
of the children had any untoward side effects except mild transient pain at
the injection site. This study demonstrated botulinum toxin is useful as an
adjunctive therapy in ameliorating spasticity in children with cerebral
palsy, especially in the younger ones.

TITLE - The role of botulinus toxin type A
in treatment--with special reference to children.
ABSTRACT - Although botulinum toxin A was
first introduced to treat strabismus and blepherospasm it is now used in an
increasing number of conditions, many in the field of pediatrics. Its action
results from a prevention of the release of acetylcholine from nerve
terminals. A number of studies recording the effects of the toxin in the
treatment of spastic cerebral palsy are reviewed, and although these can be
criticized, there seems to be no doubt that it can be of benefit. It is few
side effects, but it may reveal an underlying weakness. Other disadvantages
are its cost and the need for repeated injections. It can be used for the
relief of rigidity, although the effects in the extrapyramidal form of
cerebral palsy are not so dramatic. Also it can be beneficial in some forms
of dystonia, rarely if this is generalized, but certainly if it is focal,
and especially if there is accompanying pain. There are several conditions
seen in children, such as strabismus, blepherospasm and tremors, in which
this form of treatment will rarely be indicated; but they will be mentioned.
An exception may be spasmodic torticollis during adolescence if it does not
respond to other therapy, as it is so disabling. Botulinum toxin can be used
to block the discharges from cholinergic sympathetic and parasympathetic
terminals. Focal hyperhidrosis can be very distressing among older children,
and the use of the toxin should sometimes be considered in this and other
autonomic disorders.
