“…Our results on the concurrent validity of the VR device are in line with previous studies evaluating the validity of VR or other IMU devices for cervical ROM [ 21 , 23 ]. A previous study evaluating cervical ROM using the VR headset Oculus Rift (Irvine CA) found errors of 1.9–4.4° (SD ranging from 4.3 to 10.9°) when compared to the Optotrak Certus 3D camera-based system [ 21 ].…”

“…The larger standard deviations suggest larger LOA, but this was not analyzed. A headmounted IMU device for left and right cervical rotation measurements, when tested against the Optotrak Certus [23], also showed high ICC values (0.998), in line with our results. Sarig Bahat et al (2009) compared VR-based ROM measures performed in a VR game to a conventional measure of ROM using an electromagnetic tracking system (Fastrak, Polhemus).…”

“…Clinical assessment of ROM is commonly performed using analog methods such as goniometers, inclinometers, visual estimation, or tape measurements, with varying accuracy [ 19 ]. In research and some specialized clinics, specific laboratory equipment is used, e.g., optoelectronic camera systems [ 20 , 21 ], electromagnetic systems [ 15 ], ultrasound systems [ 22 ], or inertial measurement units (IMUs) [ 23 ]. For standardization, cervical ROM is traditionally measured in each of the sagittal, frontal, and transverse movement planes.…”

“…Objective assessment of the maximum ROM in diagonal motion may have a clinical value but has, to our knowledge, not been investigated. New affordable technology, such as virtual reality (VR) and other IMU systems, enables feasible, accurate, and automatized measurements of ROM in the clinic [ 11 , 23 , 24 , 25 ].…”

Reduced cervical range of motion (ROM) and movement velocity are often seen in people with neck pain. Objective assessment of movement characteristics is important to identify dysfunction, to inform tailored interventions, and for the evaluation of the treatment effect. The purpose of this study was to investigate the concurrent validity of a newly developed VR technology for the assessment of cervical ROM and movement velocity. VR technology was compared against a gold-standard three-dimensional optical motion capture system. Consequently, 20 people, 13 without and 7 with neck pain, participated in this quantitative cross-sectional study. ROM was assessed according to right/left rotation, flexion, extension, right/left lateral flexion, and four diagonal directions. Velocity was assessed according to fast cervical rotation to the right and left. The correlations between VR and the optical system for cervical ROM and velocity were excellent, with intraclass correlation coefficient (ICC) values > 0.95. The mean biases between VR and the optical system were ≤ 2.1° for the ROM variables, <12°/s for maximum velocity, and ≤3.0°/s for mean velocity. In conclusion, VR is a useful assessment device for ROM and velocity measurements with clinically acceptable biases. It is a feasible tool for the objective measurement of cervical kinematics in the clinic.

Objectives This study aimed to determine the validity and reliability of a new device called MOTI for measuring balance by comparing its performance that with of the gold-standard force platform. Methods The study involved collecting data from both devices in dual- and single-leg standing positions with eyes open and closed and using statistical measures to compare their performance. Results The results showed that MOTI can accurately measure balance during dual-leg standing tasks but has poor to moderate performance during single-leg standing tasks. However, it could detect small changes in postural sway caused by a reduced base of support and/or visual feedback. The study also found that the test-retest reliability was poor to moderate for both devices. Conclusions These findings suggest that MOTI has potential as a reliable tool for measuring balance during certain tasks, but further research is needed to improve its performance during single-leg standing. This study provides valuable insights into the validity and reliability of MOTI for measuring balance and highlights the need for further investigation.
