Design outcomes

Primary

MeasureTime frame
Main Objective: To demonstrate that Intrathecal Baclofen Therapy (ITB) Therapy, compared to Best Medical Treatment (BMT), has superior efficacy in the treatment of severe spasticity in adult post-stroke patients with genera-lized spastic hypertonia who have not reached their therapy goal with other treatment interventions assessed by a decrease in the average Ashworth Scale (AS) score in the lower extremities.;Secondary Objective: To evaluate safety (Adverse Events (AE)) in ITB Therapy and BMT. To evaluate the differences between ITB Therapy and BMT on: 1. Spasticity in the upper extremities assessed by AS 2. Function assessed by Functional Independence Measure (FIM) 3. Function assessed by 10 meter timed walking test (10MTWT; High Level Functional Patients only) 4. Function assessed by ability to transfer 5. Pain assessed by Numeric Pain Rating Scale (NPRS) 6. Primary therapy goal achievement assessed by Goal Attainment Scale (GAS) 7. Quality of Life (QoL) assessed by EuroQol group – 5 Dimensional (EQ-5D) 8. QoL assessed by the Stroke Specific – Quality of Life (SS-QoL) 9. Satisfaction with the therapy assessed by Likert Scale (patient and ca-regiver) 10. Healthcare resource utilization ;Primary end point(s): The average AS will be calculated as an average of the AS value on following lower extremeties muscles: hip flexors, hip adductors, knee extensors, knee flexors, plantar flexors and ankle-dorsal flexors. Change in the average AS from baseline to 6 months visit.
