The effects of VR training for the condition of FAI were not comparable to conventional training. However, VR training may be added to the conventional training programme as an optional for the condition of FAI. Implications for Rehabilitation Functional ankle instability (FAI) is subjective feelings of ankle instability resulting from proprioceptive and neuromuscular deficits in which individuals may experience "giving way" condition of the ankle. Therapeutic applications of virtual reality (VR) may be comparable to traditional rehabilitation interventions (TRI) in the rehabilitation of individuals with FAI. However, there is no definitive evidence for the issue. Integrating low-cost VR into functional rehabilitation programme can provide insight into an issue of whether it can be replaced with traditional therapeutic approaches. Although, the efficacy of VR application on strengthening muscles is unable to compare to traditional strengthening programmes, it may be considered an optional treatment based on the proprioceptive improvements.

LR should be recommended over AR for individuals with chronic LBP. Moreover, the application of ALR should be approached carefully on the basis of progress and ability to stabilize the spine in this patient population.

Studies provide convincing arguments to support the development of functional capacity instruments based on the Dictionary of Occupational Titles (DOT). The purpose of this study is to investigate the item-level measurement qualities of a newly developed DOT-based functional capacity instrument for clients undergoing rehabilitation treatment for back pain. Client and therapist ratings were collected on 124 clients from 27 rehabilitation sites using the newly developed Occupational Rehabilitation Data Base (ORDB) functional capacity instrument. Rasch analysis was used to investigate: (1) unidimensionality, (2) hierarchical item difficulty continuum, (3) rater severity, and 4) person-item match. Overall, the functional capacity scale of the ORDB showed good measurement qualities. All items, except the Handling item fit the Rasch measurement model. Because of high fit statistics and loading on factors independent from the remainder of the items, the "handling" item was removed, from further analyses. Separate client-rated and therapist-rated instruments retained good item-level psychometrics. While client and therapist items showed similar item-difficulty hierarchical structures, clients had a tendency to be more severe in their rating and the correlation between client and therapist ratings was relatively low, 0.32. These findings suggest that Handling items should not be included as a DOT measure for clients with back pain. While the above psychometric study supports using client or therapist ratings as independent instruments, the lack of concordance between these ratings requires further investigation.
