Article Abstract

Background: The use of virtual reality (VR) technology in rehabilitation therapy has been growing, leading to the development of VR-based upper-limb rehabilitation softwares. To ensure the effective use of such software, usability evaluations are critical to enhance user satisfaction and identify potential usability issues.

Objective: This study aims to evaluate the usability of a VR-based upper-limb rehabilitation software from the perspective of occupational therapists. Specifically, the study seeks to identify usability challenges and provide insights to improve user satisfaction.

Methods: The VR-based upper-limb rehabilitation software was tailored for therapists to operate while delivering therapy to patients. Usability testing was conducted with occupational therapists from the Korean National Rehabilitation Center using cognitive walkthroughs and surveys. Participants performed tasks that simulated real clinical scenarios, including turning the device on, assisting patients with wearing the device, and shutting it down. Observers recorded user reactions during task performance, and participants completed surveys to assess the ease of use of the user interface. This mixed-methods approach provided qualitative insights into user difficulties and their root causes.

Results: Usability evaluations were conducted with 6 participants. Cognitive walkthroughs revealed potential areas for improvement in the software, including (1) enhancements to the graphical user interface for ease of use, (2) refinements in the natural user interface, and (3) better user manuals for clearer product instructions. The ease-of-use score for the user interface averaged 1.58 on a 5-point scale (1=very easy to 5=very difficult).

Conclusions: This study provides valuable insights into improving user satisfaction by focusing on the needs of occupational therapists who operate a VR-based rehabilitation software. Future research should explore software refinement and clinical efficacy to maximize the therapeutic potential of such technologies.

Purpose: To compare the accuracy of static guided surgery using a pilot drill guide and dynamic guided surgery for dental implant placement.

Materials And Methods: Partially edentulous adult patients requiring implant placement were randomly assigned to either the static guided surgery group using a pilot drill guide or the dynamic guided surgery group. Digital implant planning was conducted using intraoral scans and CBCT with planning software to determine the optimal prosthetic position.

Background: Acute myocardial infarction (MI), as a serious and fatal heart disease and an important medical emergency, imposes the large financial burden on the health and treatment systems of countries and the family economy. In the meantime, starting rehabilitation programs after acute myocardial infarction as soon as possible can minimize the unfortunate and irreparable side effects. Therefore, the present study was conducted with the aim of evaluating the effectiveness of an educational program on health index in the MI patients hospitalized in CCU ward.

Purpose: To explore the concurrent validity and responsiveness of the Wheelchair Skills Test-Questionnaire (WST-Q) caregiver proxy, and the inter- and intra-rater reliability of the Wheelchair Skills Test (WST) in children and young adults with cerebral palsy (CP).

Methods: Concurrent validity and responsiveness of the WST-Q caregiver proxy were assessed in 12 participants with CP (mean age 15 years; SD: 3 years 6 months); power wheelchair users. Concurrent validity of the WST-Q was determined using Pearson's correlation coefficients, and responsiveness with linear regression.
