Abstract

Background/Objective

Limb activation is one of the behavioural interventions to improve unilateral spatial neglect (USN). However, the effect of passive limb activation on activities of daily living (ADL) is not clear. This study examined the effect of passive limb activation by functional electrical stimulation (FES) on wheelchair driving for patients with USN, and to discuss the possibility of application of this treatment to occupational therapy.

Methods

A single subject design-baseline-intervention-baseline (ABA′), was applied to 2 stroke patients with USN. Phase A and A′ consisted of the wheelchair driving task only. Phase B consisted of the wheelchair driving task with FES. Each phase lasted for 2 weeks. The wheelchair driving task was maneuvering on a square passage in the clockwise and counter clockwise conditions for 8 minutes respectively, and four obstacles were set at each side. FES was applied to the affected forearm extensor muscles. Assessor recorded: 1) The distance participants drove wheelchair for 8 minutes, and 2) The number of collisions with obstacles and the wall, for 10 days.

Results

For one participant, the distance of maneuvering significantly increased in phase B (p < .05.), and USN on the cognitive test in the extrapersonal space indicated a tendency to improve after phase B.

Conclusion

Passive limb activation by FES improved wheelchair driving and cognitive performance for patients with USN. It can be used with instruction from occupational therapists to enhance the performance on ADL.

功能性电刺激被动肢体激活对单侧空间忽视患者轮椅驾驶的影响

背景/目的激活肢体是改善单侧空间忽视(USN)的行为干预措施之一。然而，肢体被动激活对日常生活活动(ADL)的影响尚不清楚。本研究探讨了功能电刺激被动肢体激活对USN患者轮椅驾驶的影响，并探讨了将其应用于职业治疗的可能性。方法对2例脑卒中合并USN患者采用单受试者设计-基线-干预-基线(ABA ')方法。阶段A和阶段A只包括轮椅驾驶任务。阶段B包括使用FES驾驶轮椅的任务。每个阶段持续2周。轮椅驾驶任务分别在顺时针和逆时针条件下在正方形通道上机动8分钟，每边设置4个障碍物。将FES应用于受累前臂伸肌。评估员记录:1)参与者驾驶轮椅的距离为8分钟，2)与障碍物和墙壁的碰撞次数，为期10天。结果1名受试者在B阶段的机动距离显著增加(p <结论FES被动肢体激活可改善USN患者的轮椅驾驶和认知能力。它可以在职业治疗师的指导下使用，以提高ADL的表现。
