Bobath therapy is inferior to task-specific training and not superior to other interventions in improving arm activity and arm strength outcomes after stroke: a systematic review

Question: What is the effect of Bobath therapy on arm activity and arm strength compared with a dose-matched comparison intervention or no intervention after stroke?Design: Systematic review of rando-mised trials with meta-analysis. Participants: Adults after stroke.Intervention: Bobath therapy compared with no intervention or other interventions delivered at the same dose as the Bobath therapy. Outcome measures: Arm activity outcomes and arm strength outcomes. Trial quality was assessed with the PEDro scale. Results: Thirteen trials were included; all compared Bobath with another intervention, which were categorised as: task-specific training (five trials), arm movements (five trials), robotics (two trials) and mental practice (one trial). The PEDro scale scores ranged from 5 to 8. Pooled data from five trials indicated that Bobath therapy was less effective than task-specific training for improving arm activities (SMD -1.07, 95% CI -1.59 to -0.55). Pooled data from five trials indicated that Bobath therapy was similar to or less effective than arm movements for improving arm activities (SMD -0.18, 95% CI -0.44 to 0.09). One trial indicated that Bobath therapy was less effective than robotics for improving arm activities and one trial indicated similar effects of Bobath therapy and mental practice on arm activities. For strength outcomes, pooled data from two trials indicated a large benefit of task-specific training over Bobath therapy (SMD -1.08); however, this estimate had substantial uncertainty (95% CI -3.17 to 1.01). The pooled data of three trials indicated that Bobath therapy was less effective than task-specific training for improving Fugl-Meyer scores (MD -7.84, 95% CI -12.99 to -2.69). The effects of Bobath therapy relative to other interventions on strength outcomes remained uncertain.Conclusions: After stroke, Bobath therapy is less effective than task-specific training and robotics in improving arm activity and less effective than task-specific training on the Fugl-Meyer score.
