Background Exposure to brain injury via blast or blunt mechanisms disrupts multiple sensorimotor systems simultaneously. Large numbers of US Gulf War era and Operation Iraqi/Enduring Freedom veterans with traumatic brain injury (TBI) are suffering the symptom of dizziness - presumed due to "Multi-Sensory Impairment", a clinical pattern of damage to the auditory, visual and vestibular sensorimotor systems. Objective To describe the oculomotor response to rapid head rotation in a population of veterans with dizziness. We also describe the reliability of using the video head impulse test (vHIT) in a veteran population. Methods We used the vHIT to evaluate the vestibular-ocular reflex (VOR) gain and presence of compensatory saccades (CS) in each semicircular canal of 81 veterans (31% TBI) with dizziness. Data was collected using the ICS Otometric™ vHIT. Data was processed using both the Otometric™ software and custom software written in MATLAB™. This data was evaluated through Kruskal-Wallis rank-sum test and analysis of regression. Results Veterans with dizziness recruit CS in all semicircular canal planes even though their VOR gain is normal. The vHIT is a reliable clinical test to quantify the metrics of the VOR and CS in veterans. Conclusion Veterans with dizziness symptoms use compensatory saccades in all planes of semicircular canal rotation, despite having normal peripheral VOR gain during rapid head rotation. The video head impulse test is a stable measure of vestibular slow phase and metrics of compensatory saccades in veterans with dizziness.

To explore the views of women who attended a specialist antenatal nutrition clinic that was specifically developed and piloted for pregnant women with a BMI ≥ 40 kg/mA phenomenological approach, using individual interviews, was employed. Discussions were audio recorded, transcribed verbatim and scrutinised using Interpretive Phenomenological Analysis. Themes were pinpointed and supported with direct quotes to demonstrate results.Eight women, with a BMI ≥ 40 kg/mThree main themes emerged: 1) Motivation to be Healthy; 2) Woman Centred Nutrition Care; 3) Conflicts, Confusion and Assumptions.Pregnant women with a BMI ≥ 40kgm

Objective Deficits in vestibular function increase the risk for falls while turning. However, the clinical assessment of turning in patients with vestibular dysfunction is lacking, and evidence is limited that identifies the effectiveness of vestibular physical therapy in improving turning performance. The purpose of this study was to quantify walking and turning performance during the instrumented Timed “Up & Go” (TUG) test using body-worn inertial measurement units (IMUs). Novel instrumented TUG parameters were investigated for ability to distinguish patients with unilateral vestibular deafferentation (UVD) from control groups and discriminate the differences in turning parameters of patients with UVD following vestibular physical therapy. Methods Thirty-eight individuals were recruited following UVD surgery: 26 age-matched veteran controls with reports of dizziness not from a peripheral vestibular origin, and 12 age-matched healthy controls. Participants were donned with IMUs and given verbal instructions to complete the TUG test as fast as safely possible. The IMU-instrumented and automated assessment of the TUG test provided component-based TUG parameters, including the novel walk:turn ratio. Among the participants with UVD, 19 completed an additional instrumented TUG testing after vestibular physical therapy. Results The walk:turn time ratio showed that turning performance in patients with UVD before rehabilitation is significantly more impaired than both the individuals with nonperipheral conditions and healthy controls. Vestibular rehabilitation significantly improved turning performance and “normalized” their walk:turn time ratio compared with healthy controls. The duration of the straight walking component in individuals with UVD before vestibular physical therapy, however, was not significantly different compared with that component in people after vestibular physical therapy and in healthy controls. Conclusion The IMU-instrumented TUG test can be used to distinguish individuals with vestibular deafferentation and to objectively quantify the change in their turning performance after vestibular physical therapy. Impact The IMU-based instrumented TUG parameters have the potential to quantify the efficacy of vestibular physical therapy and be adopted in the clinic.

To examine inter-rater, intra-rater and test-re-test reliability of the Community Balance and Mobility Scale (CBM) and compare reliability in live vs videotape rating contexts for children with acquired brain injury (ABI).Repeated measures design.Seven physiotherapists (PTs) were trained as assessors. The primary assessor administered and scored baseline CBM while the second assessor observed and scored independently (inter-rater reliability). Re-assessment occurred 3-10 days later by primary assessor (test-re-test reliability). Assessments were videotaped.There were 32 participants with ABI (mean age = 14 years 1 month (SD = 2 years 1 month)). Baseline mean scores were 67.4% (18.2) and 66.7% (18.3) for primary and second assessor, respectively. Primary assessors' re-test mean score was 69.3%. Inter-rater reliability ICC was 0.93 (95% confidence interval (CI) = 0.87-0.97). Test-re-test ICC was 0.90 (95%CI = 0.81-0.95) and Bland-Altman plot indicated greatest test-re-test differences for mid-range CBM scores. Minimum detectable change (MDC₉₀) was 13.5% points.The CBM showed excellent reliability in youth. Reliability was comparable for live and videotape rating approaches, meaning that the easier and less expensive live-rating can be recommended. Future work should focus on evaluation of responsiveness to change in rehabilitation centre and community intervention contexts.

Collaborative goal setting between clinicians and clients/families is considered a fundamental component of the pediatric rehabilitation process. However, truly client-centered goal setting is not without its challenges. The purpose of this paper is to highlight theoretical concepts relevant to rehabilitation goal setting, review clinical studies directly evaluating relationships between goal setting and pediatric rehabilitation outcomes, and provide recommendations to facilitate collaborative goal processes. Four theoretical frameworks were identified that may lie behind and help explain the effectiveness of collaborative goal setting. The four relevant outcome studies found in the review revealed that individualized goal setting is an important component of the intervention, engages families more actively in therapy, and is associated to some extent with positive outcomes. The evidence suggests that the impact of fully collaborative goal setting is sufficiently positive to support investment of organizational and individual time, energy, and resources to make it an integral part of the rehabilitation process.
