[Purpose] The trunk muscles frequently become weak after
stroke, thus impacting overall
activities of daily living. However,
activities of daily living items closely related with trunk strength remain unclear. This study aimed to clarify the influence of trunk
muscle weakness on
activities of daily living items. [Subjects] The subjects were 24
stroke patients who fulfilled the following inclusion criteria: first
stroke and the absence of severe
paralysis, marked cognitive function deterioration, unilateral spatial neglect or apathy. [Methods] According to abdominal strength, the 24 patients were divided into a nonweakness group and a weakness group. For the assessment, we used the
stroke impairment assessment set, the Berg balance scale, a simple test for evaluating hand function, grip strength, and functional independence measure scale scores and the results were compared between the groups. [Results] The Berg balance scale score and scores for dressing,
toilet use, transfer to bed, and walk items of the functional independence measure were significantly lower in the weakness group than in the nonweakness group. [Conclusion] Our results suggest that weakness of the abdominal muscles adversely impacts the balance of patients with mild
stroke as well as their ability to dress, use a
toilet, transfer, and walk. Trunk training, including abdominal muscle exercises, can effectively improve the performance of these
activities of daily living items.
