ABSTRACT
PURPOSE: Freezing of gait (FOG) is a disabling phenomenon defined by the periodic absence or reduction of forward progression of the feet despite the intention to walk. We sought to understand whether Google Glass (GG), a lightweight wearable device that provides simultaneous visual-auditory cues, might improve FOG in parkinsonism. METHODS: Patients with parkinsonism and FOG utilized GG custom-made auditory-visual cue applications: "Walk With Me" and "Unfreeze Me" in a single session intervention. We recorded ambulation time with and without GG under multiple conditions including 25 feet straight walk, dual task of performing serial 7's while straight walking, 180 degree turn after walking 25 feet, and walking through a doorway. FOG and patient experience questionnaires were administered. RESULTS: Using the GG "Walk With Me" program, improvements were noted in the following: average 25 feet straight walk by 0.32 s (SD 2.12); average dual task of serial 7's and 25 feet straight walk by 1.79 s (SD 2.91); and average walk through doorway by 0.59 s (SD 0.81). Average 180 degree turn after 25 feet walk worsened by 1.89 s (SD 10.66). Using the "Unfreeze Me" program, only the average dual task of serial 7's and 25 feet straight walk improved (better by 0.82 s (SD 3.08 sec). All other tasks had worse performance in terms of speed of completion. CONCLUSION: This feasibility study provides preliminary data suggesting that some walking tasks may improve with GG, which uses various musical dance programs to provide visual and auditory cueing for patients with FOG.IMPLICATIONS FOR REHABILITATIONFreezing of gait in parkinsonian syndromes is a disabling motor block described by patients as having their feet stuck to the floor leading to difficulty in initiation of gait and increased risk for falls.Wearable assistive devices such as Google Glass™ use visual and auditory cueing that may improve gait pattern in patients with freezing of gait.Augmented reality programs using wearable assistive devices are a home-based therapy, with the potential for reinforcing physical therapy techniques; this is especially meaningful during the COVID-19 pandemic when access to both medical and rehabilitative care has been curtailed.
ABSTRACT
BACKGROUND: Patient education is an essential part of management of complex, disabling neurological disorders. Mobile web-based educational materials provide a novel and potentially valuable means to communicate clinical information that can aid in both medical management and rehabilitation. AIMS: We, therefore, evaluated an educational tablet-based intervention in three patient cohorts regarding the following topics: Parkinson's disease (PD) medications, dystonia and botulinum toxin treatment. METHODS: A total of 50 subjects with PD, 32 with dystonia and 61 receiving botulinum toxin treatment for movement disorders or sialorrhoea were enrolled. Participants in each cohort completed a specific educational module at the time of their regularly scheduled clinic visit, comprising slides, in addition to pre- and post-module quizzes and a satisfaction survey. Additionally, participants in the dystonia and botulinum toxin modules were given a follow-up test at their 3- or 6-month clinical treatment visit. RESULTS: There were 143 participants with 50 completing the PD module, 32 completing the dystonia module and 61 completing the botulinum toxin module. All three groups demonstrated significant improvement in knowledge of module content between their pre- and post-module test scores (PD: p=.0001, dystonia: p<.0001 and botulinum toxin: p=.008), and those who took the dystonia module maintained significant improvement at either a 3- or 6-month follow up compared to pre-module (p <.0001). CONCLUSIONS: Tablet-based teaching modules are an effective means of communicating key concepts to patients. This study supports their use for improving patient understanding that can support lifelong approaches to managing disabling, neurological conditions.Implication for RehabilitationTablet-based modules are relatively easy to use for enhancing education during clinic visits and can possibly help reduce and maintain disability with chronic conditions like Parkinson's disease and dystonia.Improvements in post-test scores suggested that patient participants were able to retain information from the tablets about their complex and challenging conditions and treatments.Adding patients who are fluent in another language would have made this study more generalizable and future studies exploring educational interventions are warranted to help better tailor interventions to patients with chronic neurologic illnesses to help understand the complex aspects of their medical and rehabilitation therapy.The effect of cognitive changes in neurological conditions and understanding of educational information needs to be further tested.This positive result is especially meaningful during the COVID-19 pandemic when in-person access to both medical and rehabilitative care has been curtailed.
