Influence of Assistive Device Use While Performing Dual Task in Patients With Stroke

Trial Description

The primary purposes of the this three-year research proposal are to investigate the influence of assistive device use on dynamic balance and the associated attentional demands during standing and walking in patients with stroke

Detailed Description

Research has shown the effectiveness of using ambulatory assistive devices to increase standing stability of patients with stroke in clinical practice (Maeda et al., 2001). However, literature has also suggested that manipulation of ambulatory assistive devices in dynamic motor tasks, such as walking, inevitably requires additional attention, even in healthy adults (Wright & Kemp, 1992). Given that the majority of patients with stroke suffer from balance control difficulty, which subsequently increases their attentional demands associated with maintaining balance (Brown et al., 2002), it remains an important question as to whether the use of ambulatory assistive devices would take away some attentional resources that would otherwise be used for maintaining balance.

Outcomes

Type Measure Time Frame Safety Issue
Primary To investigate the voice reaction time and response accuracy while simultaneously performing the dual task with or without using assistive devices for healthy adults and stroke patients
Secondary To investigate the related gait parameters(ex. walking speed, stride length, gait cycle time, and foot pressure etc.)while simultaneously performing the dual task with or without using assistive devices for healthy adults and stroke patients
