Qobjective compared the reliability of standard goniometers with virtual reality (VR) for measuring cervical active ranges of motions (AROM) in six motions. The study compared goniometric methods taught to students with those using VR methods with the Oculus Rift in the measurement of cervical AROM.
Students recorded cervical motions with goniometers and VR with students paired with one blind to the numbers on the goniometer while the other recorded cervical AROM for all 40 subjects. The same condition was met for the VR measurements in a randomized control sequence.
Setting : The study was performed on the college campus with the health science building in the observation room.
Participants (or Animals, Specimens, Cadavers) :
40 adults comprised the study group of participants ages 22 to 70 years old of both genders ranging from students, faculty, staff, community members. Based on an intraclass correlation coefficient (ICC) of 0.90 and 0.95, an 80% power, an appropriate sample of 40 was chosen for this study.
Each participant moved their head in right rotation, left rotation, extension, flexion, left-side bending, and right-side bending. The same instructions for both methods with a brief survey to collect their subjective perceptions upon completion.
Main Outcome Measure(s) :
The resulting main outcome measure suggests a directional pedagogical shift in the teaching of future physical therapy students for more technology in the assessment, examination, and treatment of patients.
Results : Currently, the study is 75% complete but early indications are for higher reliability outcomes using VR systems over goniometric methods. VR methods show more consistent objective data capture and 50% faster. Subject surveys reflect a preference for motions to be taken by VR with easier to follow instructions while avoiding any temptation to compensate for certain cervical motions.
Conclusions : Data suggests health-related educational programs should consider using more technology as part of patient examinations, re-examinations, and even for treatment interventions using technology. It will improve the preparation of future health care professional for the contemporary health care settings, which will include the expansion of more community-based health care interactions.
