Background: Falls are common in elderly individuals and those with neurological conditions like Parkinson's disease. Parkinson's disease causes postural instability and mobility issues that lead to falls and reduced quality of life. The fear of falling (FoF), a natural response to unstable balance, can exacerbate postural control problems. However, evaluating FoF relies primarily on subjective self-reports due to a lack of objective assessment methods.
Objectives: This mixed-methods feasibility study aims to develop an objective method for assessing fear of falling during motion and walking using virtual reality. This protocol examines a range of FoF-related responses, including cognitive, neuromuscular, and postural stability factors.
Methods: Individuals without and with Parkinson's disease will complete questionnaires, movement tasks, and walking assessments in real and virtual environments where FoF can be elicited using virtual reality (VR) technology. Data from center-of-pressure measurements, electromyography, heart rate monitoring, motion capture, and usability metrics will evaluate the method's acceptability and safety. Semi-structured interviews will gather participants' and researchers' experiences of the protocol.
Discussion: This method may allow accurate assessment of how FoF impacts movement by measuring cognitive, neuromuscular, and postural responses during gait and motion. Virtual environments reproduce real-life scenarios that trigger FoF. Rigorously assessing FoF with this approach could demonstrate its ability to quantify the effects of FoF on movement.
Conclusions: This protocol aims to improve FoF assessment by evaluating multiple responses during movement in virtual environments. It addresses current measures' limitations. A feasibility study will identify areas for improvement specific to Parkinson's disease. Successful validation could transform how FoF is evaluated and managed.

the Suitability Evaluation Questionnaire (SEQ) is the SEQ Suitability Evaluation Questionnaire for Virtual Rehabilitation Systems. The range of scores is 0 to 100, with higher scores indicating a better outcome. The SEQ is scored by summing the responses to the 14 items. The items are scored on a 7-point Likert scale, with 1 = strongly disagree and 7 = strongly agree. The total score can range from 0 to 98. A higher score on the SEQ indicates that the VR system is perceived as being more user-friendly, enjoyable, and safe. This suggests that the patient is more likely to use the VR system and to benefit from it. |

| Sense of Presence | The iGroup Presence Questionnaire (IPQ) has a range of scores is 0 to 6, with higher scores indicating a better outcome. The IPQ is scored by summing the responses to the 14 items. The items are scored on a 7-point Likert scale, with 1 = disagree strongly and 7 = agree strongly. The total score can range from 0 to 98. A higher score on the IPQ indicates that the user feels more present in the Virtual environment (VE).

The items are scored on a 5-point scale, with 0 = no problem and 4 = severe problem. The total score can range from 0 to 100, with a lower score indicating better quality of life. | 45 minutes |
| Balance confidence | Balance confidence will be evaluated using Activity-specific Balance Confidence scale (ABC scale). Which is a self-administered scale to indicate the level of confidence the person has in doing the activity without losing his/her balance. The ABC is an 16 point scale and ratings should consist of whole numbers (0 to 100) for each item. Total the ratings and divide by 16 to get each subject's ABC score. | 10 minutes |
