Outcome Measures

Primary Outcomes (1)

  • Muscle tonus reduction will be assessed by the Ashworth Scale.

    time of allocation, four, twelve, sixteen and twenty-four weeks after first application of toxin.

Secondary Outcomes (4)

  • Life quality will be assessed by WHOQOL-Bref, YQOL-R and Children's Life Quality assessment questionnaire, respecting the age of the patient.

    time of allocation, twelve and twenty-four weeks after first application of toxin.

  • Functional capability will be evaluated through the Functional Independence Measure Scale (FIM) for adults and PEDI scale for children.

    time of allocation, twelve and twenty-four weeks after first application of toxin.

  • Incidence, severity and duration of adverse effects of each treatment, through adverse events scale.

    every follow-up visit.

  • Perception of improvement of the symptoms by the patient himself or caregiver.

    every follow-up visit.

Study Arms (2)

1-BTA Lanzhou/Allergan

ACTIVE COMPARATOR

Patients randomly allocated to this arm will receive botulinum toxin type A from laboratory Lanzhou at allocation and after twelve weeks will receive the same drug from laboratory Allergan.

Drug: Botulinum toxin type A from laboratory LanzhouDrug: Botulinum toxin type A from laboratory Allergan

2. BTA Allergan/Lanzhou

ACTIVE COMPARATOR

Patients randomly allocated to this arm will receive botulinum toxin type A from laboratory Allergan at allocation and after twelve weeks will receive the same drug from laboratory Lanzhou.

Drug: Botulinum toxin type A from laboratory LanzhouDrug: Botulinum toxin type A from laboratory Allergan

Interventions

Patients will receive botulinum toxin type A from laboratory Lanzhou either at time of allocation (arm BTA Lanzhou/Allergan) or three months later (arm BTA Allergan/Lanzhou), so that all patients will receive both drugs in a crossover model. Application will be performed according to standard protocol and respecting parameters of the patients former sessions (if there were any), by a trained investigator, unaware of the kind of TBA in use. Standard dilution will be employed, within the usual dose and application spots (for patients already in treatment) or standard (for patients yet to start treatment). Identical dose will be used, with 2ml of saline solution 0,9% dilution for each 100units, thus, there will be no difference for the patient or investigator concerning the applicated volume.

Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • To be included, patients must have diagnosis of Spasticity by IC10 criteria.
  • We will enroll patients on current treatment for spasticity at the Spasticity outpatient clinic of HCPA, already in treatment with BTA or starting that treatment based on their doctors' decision, who are willing to participate in the trial by signing an informed consent form.
