The objective of this study is to demonstrate the effect of intramuscular BoNT-A injections in relieving pain, in a broad population of patients who suffer pain as the primary problem associated with spasticity. Thus, this study will help to expand the information that is available regarding the impact of BoNT-A treatment in routine clinical practice conditions.

Treatment goals can vary greatly from one patient to another and there is no unique, single outcome that reflects the treatment benefits in all the cases. Therefore, this study with special focus on the achievement of therapeutic goals, will allow the identification of each patient's specific goals regarding the improvement of the functional outcomes, the quality of life and patient well-being.

Condition Intervention
Lower Limb Spasticity
Drug: Botulinum Toxin Type A (BoNT-A) Injection

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: A Prospective, Observational Study to Assess Pain Relief After 4 Botulinum Toxin Type A (BoNT-A) Injection Cycles in Patients With Post-stroke Lower Limb Spasticity

Further study details as provided by Ipsen:

Primary Outcome Measures:
  • Change in Pain relief on Numeric Rating Scale [ Time Frame: Baseline visit and every 4 months up to 16 months (Visit 5). ] [ Designated as safety issue: No ]
    Pain relief evaluated by Numeric Rating Scale (NRS). The NRS score for patient self-reporting of pain ranging from 0 (no pain) to 10 (the most severe pain).

Secondary Outcome Measures:
  • Change in Pain relief on Visual Assessment Scale [ Time Frame: Baseline visit and every 4 months up to 16 months (Visit 5). ] [ Designated as safety issue: No ]
    Pain relief evaluated by measuring changes in Visual Assessment Scale (VAS). The VAS used a 100 mm line in which values were reported, 0 (no pain) to 10 (the most severe pain).

  • Responder rate using goal Attainment Scale [ Time Frame: Every 4 months up to 16 months (Visit 5). ] [ Designated as safety issue: No ]
    Responder rate assessed on the Goal Attainment Scale (GAS). GAS is a 5-point scale, with the degree of attainment captured for each goal area.

Estimated Enrollment: 184
Study Start Date: April 2014
Estimated Study Completion Date: April 2018
Estimated Primary Completion Date: April 2018 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
