Objective: To evaluate changes in temporospatial gait parameters after intrathecal baclofen (ITB) bolus administration in patients with spasticity resulting from acquired brain injury by using computerized gait analysis. Design: Case series; before-after intervention. Walking performance and spasticity in lower-extremity muscles were assessed before and at 2, 4, and 6 hours after ITB bolus injection. Setting: Tertiary care free-standing rehabilitation hospital. Participants: Consecutive sample of 28 adults with acquired brain injury due to stroke, trauma, or anoxia. Intervention: A 50-mu g ITB bolus injection (2 subjects received 75 mu g and 100 mu g, respectively). Main Outcome Measures: Ashworth Scale scores, self-selected gait velocity, stride length, cadence, step length symmetry, step width, and percentage of single support on the more involved side. Results: Ashworth score decreased from 2.0 +/- 0.5 at baseline to 1.3 +/- 0.3 at peak response (P < .001), whereas gait velocity increased from 41 +/- 26 to 47 +/- 31cm/s Langue : ANGLAIS |
