These initial results demonstrated sound statistical properties of the IHS and usefulness as a hyperacusis measurement tool in research and clinical practice. Factor structure and scale dimensions allow for differentiation between subtypes of loudness, annoyance, fear, and pain based on responses to clusters of specific items within the dimensional factor structure of the scale, and may thus prove useful in clinical practice and research.
Test); and a validated VE user questionnaire. Results: 18 participants (20 enrolled) completed the study (8 PT and 10 VE). Body mass index was higher (pZ0.02) and time from disease onset was shorter (pZ0.02) in the PT group. No statistically significant between-group differences in change on outcome measures were observed. There were significant within-group pre-post intervention changes for PT (T25FW velocity pZ0.01, dZ0.62; stride length pZ0.02, dZ0.38; PHQ-8 pZ0.03, dZ-0.25), and VE (dual-task step width pZ0.01, dZ0.48; GAD-7 pZ0.04, dZ-0.58). Participant satisfaction with the VE system was high. Conclusions: We found no significant difference between PT and VE on multidimensional outcomes, while significant changes were observed within each group. Further research is needed to better understand the usefulness of virtual reality in MS rehabilitation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
