Abstract

Background

The Dual-task Augmented Reality Treatment (DART) trial recently established that dual-task training (DTT) delivered by a physical therapist or the augmented reality DART platform was effective in improving spatiotemporal gait parameters under single- and dual-task conditions in individuals with Parkinson’s disease (PD). Data regarding postural stability were not reported in the primary outcome manuscript.

Objective

The aim of this secondary analysis was to compare the effects of a Traditional DTT intervention delivered by a physical therapist and DTT delivered by the DART platform on postural stability, functional mobility, and turning in individuals with PD. It was hypothesized that both groups would experience similar improvements.

Methods

Forty-seven individuals with PD were randomized to an 8-week (16 sessions) Traditional DTT or DART intervention. The limits of stability test and the instrumented Timed Up and Go (TUG) under single- and dual-task conditions were gathered at Baseline, End of Treatment (EOT), and 8-weeks after EOT.

Results

At EOT, the Traditional DTT and DART groups experienced a 9 % and 14 % improvement in maximal excursion area and a 7 % and 12 % improvement in total TUG time under dual-task conditions, respectively (p<0.05). Turn duration and average and peak turn velocity during the TUG improved for both groups under single- and dual-task conditions at EOT. Improvements in turn duration (dual-task) and average turn velocity (single- and dual-task) persisted 8-weeks after intervention cessation.

Conclusion

Improvements in postural stability, functional mobility, and turning under single- and dual-task conditions following traditional and DART DTT in individuals with PD indicate that cognitive-motor training can be used to effectively treat postural instability in this population. Improvements in the DART group were similar to traditional DTT, supporting our previous data demontrating that DART is an effective digital therapeutic to improve gait and postural instability in individuals with PD.

增强现实双任务干预改善了帕金森病患者的姿势稳定性。

背景：双任务增强现实治疗（DART）试验最近证实，由物理治疗师或增强现实DART平台提供的双任务训练（DTT）能有效改善帕金森病（PD）患者在单任务和双任务条件下的时空步态参数。主要结果手稿中未报告有关姿势稳定性的数据：本二次分析旨在比较物理治疗师提供的传统 DTT 干预与 DART 平台提供的 DTT 对帕金森病患者姿势稳定性、功能移动性和转身的影响。假设两组患者的改善效果相似：47名帕金森氏症患者被随机分配到为期8周（16次）的传统DTT或DART干预中。分别在基线、治疗结束（EOT）和治疗结束后 8 周收集单任务和双任务条件下的稳定性极限测试和仪器定时上下楼（TUG）测试结果：结果：在治疗结束（EOT）时，传统 DTT 组和 DART 组的最大偏移面积分别提高了 9% 和 14%，双任务条件下的总 TUG 时间分别提高了 7% 和 12%（p 结论：帕金森氏症患者在接受传统和DART DTT训练后，在单任务和双任务条件下的姿势稳定性、功能移动性和翻身能力均有所提高，这表明认知运动训练可用于有效治疗该人群的姿势不稳定性。DART 组的改善效果与传统 DTT 相似，支持了我们之前的数据，证明 DART 是改善步态和姿势不稳定性的有效数字疗法。

期刊介绍： Gait & Posture is a vehicle for the publication of up-to-date basic and clinical research on all aspects of locomotion and balance. The topics covered include: Techniques for the measurement of gait and posture, and the standardization of results presentation; Studies of normal and pathological gait; Treatment of gait and postural abnormalities; Biomechanical and theoretical approaches to gait and posture; Mathematical models of joint and muscle mechanics; Neurological and musculoskeletal function in gait and posture; The evolution of upright posture and bipedal locomotion; Adaptations of carrying loads, walking on uneven surfaces, climbing stairs etc; spinal biomechanics only if they are directly related to gait and/or posture and are of general interest to our readers; The effect of aging and development on gait and posture; Psychological and cultural aspects of gait; Patient education.
