Effects of intrathecal baclofen bolus injection in CP and acquired brain injury. In patients with acquired brain injury, the ITB bolus injection significantly decreased the MAS grade in upper extremity (A) and lower extremity (B). In nonambulatory CP, the MAS grade also significantly decreased after the ITB bolus injection in upper extremity (A) and lower extremity (B). However, in ambulatory CP, the MAS grade significantly decreased after the ITB bolus injection in upper extremity (A), but not in lower extremity (B). ABI = acquired brain injury, CP = cerebral palsy, ITB = intrathecal baclofen, MAS = modified Ashworth scale. ^∗P < .05, pre-ITB test trial versus post-ITB test trial.
