Improvement After Botulinum Toxin Injections to the Arms in Children With Cerebral Palsy

April 20, 2011 updated by: Shaare Zedek Medical Center

Improvement After Botulinum Toxin A Injections to the Upper Extremities in Children With Cerebral Palsy

Hypothesis: (1) Treating upper limb hypertonia/spasticity with Botox®, in addition to reducing hypertonia/spasticity, will (a) improve global development, (b) improve function (passive & active), (c) reduce carer burden and (d) improve quality of life. (2) Early treatment with Botox® will have a greater impact on the rate of global development when compared to late treatment.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Background: Upper limb function is essential for activities of daily living impacting on quality of life in children with cerebral palsy (CP). In preschool children, dysfunctional upper extremity manipulation not only leads to disability but may further delay global development and substantially increase career burden. Even modest functional improvement could have tremendous long-term benefit in activities of daily living and significantly reduce career burden. Hypertonia is the main symptom causing motor dysfunction in CP. Intramuscular Botulinum toxin injection is one way of treatment. In spite of anecdotal evidence suggesting that early intervention can lead to better outcomes, Israeli physicians are unable to prescribe this treatment for the upper extremities due to limited health insurance coverage. A paucity research evidence is often cited as the reason for limiting the insurance coverage, in particular to the upper limb. We therefore propose to study the effects of Botox® in treating children with CP.

Method: Twenty cooperative quadriplegic CP children ages 8-11 years, gross motor function level 4, will be enrolled for the study. Inclusion criteria will be troublesome hypertonia that will respond to treatment with Botox® (as identified by clinical assessment and neurophysiological measures). Since cooperation is crucial for the intensive therapy children with cognitive impairment (IQ<70) or severe behavioural disorders will be excluded. The children will be randomized to one of two groups a Botox group (BG) and a control group (CG). CG children will undergo a program of intensive therapy and BG children will be given Botox, as clinically required, in addition to an equivalent program of intensive therapy. Botox injection will be tailored according to the specific child. Generally injection site will include biceps and brachioradialis , while flexors of the wrist and digits will be injected according to abnormal postures during function. Maximal total dose will be 23 IU per kg. The intensive therapy will be as clinically required and the therapy program will be fully documented.

Outcome measures will include the following:

  1. Hypertonia- neurophysiological measures
  2. Impairment measures - Grip and Pinch strength, active and passive range of motion at the writs elbow and shoulder
  3. Upper extremity function - Quality of Upper Extremity Skills Test (QUEST), Box and Blocks test
  4. Function and patient needs assessment - Goal Attainment Scores, Developmental Fine Motor Scale, Pediatric Evaluation and Disability Inventory (PEDI)
  5. Quality of life scales (care and comfort hypertonicity questionnaire) All of these measures will be taken once before treatment and then repeated at 7 months, and at 13 months after treatment.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
