- •Synergies were associated with posttreatment gait outcomes.
- •This association was independent of treatment group at both centers.
- •Less impaired motor control was associated with faster walking posttreatment.
- •Less impaired motor control was associated with greater improvements in kinematics.
- •Associations were similar across 2 commonly used clinical muscle sets.
