Relationship of sensory organization to balance function in patients with hemiplegia

Standing balance and dynamic weight shifting were evaluated in 10 subjects with hemiplegia using a sensory organization balance test (SOT) and the Fugl-Meyer sensorimotor assessment (FMSA). The SOT is a timed balance test that evaluates somatosensory, visual, and vestibular function for maintenance of upright posture. In contrast, the FMSA is a functional status assessment that indicates the amount of assistance needed during various balance tasks and the tolerated duration of the task. The results of both clinical tests were compared to determine whether the SOT correlated with functional ability. The SOT scores were significantly correlated with the FMSA balance subscores and the FMSA total lower extremity scores. Based on the results of this preliminary study, the authors concluded that the SOT may be useful for evaluating a patient's functional status. Further implications for the evaluation and treatment of balance dysfunction in persons with hemiplegia are discussed.
