Abstract

Background: Vibrotactile stimulation has been studied in its efficacy of reducing freezing of gait (FOG) in patients with Parkinson's disease (PD). However, the results are still controversial. We evaluated the efficacy of a newly developed vibrotactile foot device on freezing severity and gait measures in PD patients with FOG.

Objective: To evaluate the efficacy of vibrotactile foot device on PD patients with FOG.

Methods: Thirty-three PD patients with FOG were examined during their "off" medication state. The efficacy of the vibrotactile foot device was evaluated using a gait protocol comprising walking trials with vibrotactile stimulation "off" and "on." Walking trials were videotaped for the offline rating by two movement disorder specialists. The Opal inertial sensor unit (128 Hz; Mobility Lab; APDM Inc., Portland, OR, USA) was used for quantitative gait analysis.

Results: The results demonstrated 33.1% reduction in number of FOG episodes (P < 0.001) and 32.6% reduction of freezing episodes (P < 0.001). Quantitative gait analysis showed a significant increase in step length (P = 0.033). A moderate negative correlation was observed between the change of percent time frozen and age (r = -0.415, P = 0.016). 73% of participants reported minimal to substantial improvement in walking with this vibrating stimulation delivered by the vibrotactile foot device.

Conclusions: The vibrotactile foot device is an efficient device that could significantly reduce freezing severity and provide gait regulation to patients with PD experiencing frequent freezing. It could potentially be used in the home environment for improving the quality of life.

振动触觉足部装置治疗帕金森病步态冻结：一项试点研究

背景：振动触觉刺激对减少帕金森病（PD）患者步态冻结（FOG）的疗效进行了研究。然而，研究结果仍存在争议。我们评估了新开发的振动触觉足部装置对帕金森病 FOG 患者冻结严重程度和步态测量的疗效：评估振动足部触觉装置对患有 FOG 的帕金森病患者的疗效：方法：对33名患有FOG的PD患者在 "停药 "状态下进行了检查。振动触觉足部装置的疗效通过步态协议进行评估，步态协议包括振动触觉刺激 "关闭 "和 "开启 "时的行走试验。两名运动障碍专家对行走试验进行了录像，以便进行离线评级。Opal 惯性传感器装置（128 Hz；Mobility Lab；APDM Inc.，美国俄勒冈州波特兰市）用于步态定量分析：结果表明，FOG 的发作次数减少了 33.1%（P 结论：振动触觉足部装置对 FOG 的治疗效果显著：振动触觉足部装置是一种有效的装置，可显著降低僵直的严重程度，并为经常僵直的帕金森病患者提供步态调节。该装置可在家庭环境中使用，以提高生活质量。
