Design and Evaluation of Using Head-Mounted Virtual Reality for Learning Clinical Procedures: Mixed Methods Study

Immersive Virtual Reality Simulation for Learning Fundamental Nursing Skills: A Mixed-Methods Study

BACKGROUND

Literature showed that learners' perceived usability and perspective toward a technology application affected their learning experience. Fewer studies have investigated immersive virtual reality (IVR) simulation learning of fundamental nursing skills learning (FNSL).

PURPOSE

The aim of the study was to explore the perceived usability of IVR simulations for FNSL among first-year nursing students and their perspectives toward this learning modality.

METHODS

This study used a mixed-methods design with an educational intervention. Sixty-five first-year nursing students participated in 2 IVR simulation procedures in complementary mode. Surveys and focus groups were conducted in the postintervention period.

RESULTS

The findings demonstrated students' positive inclinations toward IVR simulation learning. Two areas emerged: using IVR simulation as a complementary modality for FNSL and barriers affecting students' perceived usability toward this technology.

CONCLUSIONS

With addressing the concerns from students' perceived usability, immersive virtual reality simulation could be a potential complementary modality for FNSL.

Design of Virtual Reality Exergames for Upper Limb Stroke Rehabilitation Following Iterative Design Methods: Usability Study

BACKGROUND

Since the early 2000s, there has been a growing interest in using exercise video games (exergames) and virtual reality (VR)-based interventions as innovative methods to enhance physical rehabilitation for individuals with multiple disabilities. Over the past decade, researchers and exercise professionals have focused on developing specialized immersive exercise video games for various populations, including those who have experienced a stroke, revealing tangible benefits for upper limb rehabilitation. However, it is necessary to develop highly engaging, personalized games that can facilitate the creation of experiences aligned with the preferences, motivations, and challenges communicated by people who have had an episode of stroke.

OBJECTIVE

This study seeks to explore the customization potential of an exergame for individuals who have undergone a stroke, concurrently evaluating its usability as a technological tool in the realm of physical therapy and rehabilitation.

METHODS

We introduce a playtest methodology to enhance the design of a VR exergame developed using a user-centered approach for upper limb rehabilitation in stroke survivors. Over 4 playtesting sessions, stroke survivors interacted with initial game versions using VR headsets, providing essential feedback for refining game content and mechanics. Additionally, a pilot study involving 10 stroke survivors collected data through VR-related questionnaires to assess game design aspects such as mechanics, assistance, experience, motion sickness, and immersion.

RESULTS

The playtest methodology was beneficial for improving the exergame to align with user needs, consistently incorporating their perspectives and achieving noteworthy results. The pilot study revealed that users had a positive response. In the first scenario, a carpenter presents a game based on the flexion-extension movement of the elbow; the second scenario includes a tejo game (a traditional Colombian throwing game) designed around game mechanics related to the flexion-extension movement of the shoulder; and in the third scenario, a farmer challenges the player to perform a movement combining elbow flexion and extension with internal and external rotation of the shoulder. These findings suggest the potential of the studied exergame as a tool for the upper limb rehabilitation of individuals who have experienced a stroke.

CONCLUSIONS

The inclusion of exergames in rehabilitation for stroke-induced hemiparesis has significantly benefited the recovery process by focusing on essential shoulder and elbow movements. These interactive games play a crucial role in helping users regain mobility and restore practical use of affected limbs. They also serve as valuable data sources for researchers, improving the system's responsiveness. This iterative approach enhances game design and markedly boosts user satisfaction, suggesting exergames have promising potential as adjunctive elements in traditional therapeutic approaches.
