A Novel Head Mounted Display Based Methodology for Balance Evaluation and Rehabilitation

Abstract

In this paper, we present a new augmented reality (AR) head mounted display (HMD)-based balance rehabilitation method. This method assesses the individual’s postural stability quantitatively by measuring head movement via the inertial measurement unit sensor integrated in the AR HMD. In addition, it provides visual feedback to train through holographic objects, which interacts with the head position in real-time. We implemented applications for Microsoft HoloLens and conducted experiments with eight participants to verify the method we proposed. Participants performed each of three postural tasks three times depending on the presence or absence of augmented reality, the center of pressure (COP) displacement was measured through the Wii Balance Board, and the head displacement was measured through the HoloLens. There are significant correlations (p < 0.05) between COP and head displacement and significant differences (p < 0.05) between with/without AR feedback, although most of them were not statistically significant likely due to the small sample. Despite the results, we confirmed the applicability and potential of the AR HMD-based balance rehabilitation method we proposed. We expect the proposed method could be used as a convenient and effective rehabilitation tool for both patients and therapists in the future.

Augmented Virtual Reality in Vestibular Assessment: A Dynamic Gait Application

“…Vestibular research groups have focused on the development of an effective and efficient therapy for artificially restoring the vestibular function in vestibular patients. Electrical stimulation can be divided into three subtypes: co-stimulation with a CI, direct vestibular stimulation with a VI, and GVS through surface electrodes [Sluydts et al, 2020] Several clinical applications of AR have already been proposed mainly for rehabilitative and training purposes [Lee et al, 2019;Pezzera et al, 2020;Tada et al, 2022;Blomqvist et al, 2021;Franzo et al, 2022] easy to administer and requires minimal equipment and space. Vereeck et al described a set of normative DGI values to identify healthy subjects [Vereeck et al, 2008].…”

The Hitchhiker’s Guide to Fused Twins: A Review of Access to Digital Twins In Situ in Smart Cities

“…Some of the research explicitly mentions the DT approach or a Situated Analytics approach but often simply uses the available technology to demonstrate that their problem can be addressed [428,430,431], implicitly developing a DT and applying Situated Analytics.

Review of Microsoft HoloLens Applications over the Past Five Years

“…Lee et al [44] proposed a balance rehabilitation method based on AR. This method measures the movement of the head through an inertial measurement unit sensor mounted on an AR HMD and quantitatively assesses the individual's postural stability.…”
