Quantitative assessment of postural control in patients with stroke

Objective:To discuss the quantitative assessment of postural control in patients with stroke using Smart Equitest balance master system.Method:Twenty-eight patients with 1 to 6 months post-stroke were randomly divided into a treatment group and a control group with 14 subjects in each group.Balance training with balance master system was used in the treatment group.Traditional balance training was used in the control group.Two groups received interventions 20min per time,5 times per week.Subjects were assessed using the sensory organization test(SOT)、limit of stability(LOS) and walking across test before and after 2 weeks of treatment.Result:The scores for the terms of EOSS、ECSS、SVSS in SOT test showed significant improvement post-treatment than pre-treatment and control group.The terms of EPE and DCL in LOS test showed significant improvement post-treatment than pre-treatment and control group.The step length and velocity in walking across test showed significant improvement post-treatment than pre-treatment and control group.Conclusion:Dynamic balance training can significantly improve the postural control in patients with stroke,improve the abilities of the sensation(especially the vestibular system) and motor systems based on the task-oriented and significantly improve walking ability in patients with hemiplegia simultaneously.
