Purpose The purpose of this singlecase study was to investigate the effects of trunk stabilization based on the Bobath concept on balance in a patient with cerebellar stroke. The intervention aimed to improve postural control by enhancing trunk stability and extensor muscle activation, which are essential components of the Bobath approach to neurorehabilitation. Methods A 76yearold female patient with cerebellar stroke participated in this case study. The intervention consisted of five sessions over a threeweek period, with each session lasting approximately one hour. The treatment included targeted therapeutic approaches designed to enhance trunk stability and extensor muscle activation Results Following the intervention, notable improvements were observed in the patient's postural alignment while standing against gravity. The Trunk Impairment Scale (TIS) score increased by 3 points, the Berg Balance Scale (BBS) score increased by 10 points, and the Functional Reach Test (FRT) showed a 10 cm improvement. Conclusion A threeweek intervention applying Bobathbased trunk stabilization techniques led to measurable improvements in balance in a patient with cerebellar stroke. These findings support the potential effectiveness of the Bobath concept in enhancing trunk control and balance safety in individuals with cerebellar dysfunction.
