ABSTRACTWe reviewed the public comments submitted in response to the Department of Health and Human Services' (DHHS's) original and revised proposal for mandated single‐IRB review of federally funded multisite research to see who responded to the proposed mandate and to determine what they said and how the agency addressed the public comments in its revised proposal. Our analysis indicates that support for the single‐IRB mandate was limited. The most common argument against the proposed mandate came from those concerned with the loss of site‐specific institutional review board (IRB) review of the protocol for a multisite study to address issues relevant to local context. Concerns were also raised that the single‐IRB approach would replace one inefficient system (that entails, for example, multiple reviews of a single study) with another potentially inefficient system (involving the negotiation and management of multiple interinstitutional agreements). Empirical research about the implementation of DHHS's final rule—and the separate rule of the National Institutes of Health—mandating single‐IRB review is needed to determine whether the single‐IRB model achieves the stated goals.

BACKGROUND: A clinical pattern of damage to the auditory, visual, and vestibular sensorimotor systems, known as multi-sensory impairment, affects roughly 2% of the US population each year. Within the population of US military service members exposed to mild traumatic brain injury (mTBI), 15–44% will develop multi-sensory impairment following a mild traumatic brain injury. In the US civilian population, multi-sensory impairment-related symptoms are also a common sequela of damage to the vestibular system and affect ~ 300–500/100,000 population. Vestibular rehabilitation is recognized as a critical component of the management of multi-sensory impairment. Unfortunately, the current clinical practice guidelines for the delivery of vestibular rehabilitation are not evidence-based and primarily rely on expert opinion. The focus of this trial is gaze stability training, which represents the unique component of vestibular rehabilitation. The aim of the Incremental Velocity Error as a New Treatment in Vestibular Rehabilitation (INVENT VPT) trial is to assess the efficacy of a non-invasive, incremental vestibular adaptation training device for normalizing the response of the vestibulo-ocular reflex. METHODS: The INVENT VPT Trial is a multi-center randomized controlled crossover trial in which military service members with mTBI and civilian patients with vestibular hypofunction are randomized to begin traditional vestibular rehabilitation or incremental vestibular adaptation and then cross over to the alternate intervention after a prescribed washout period. Vestibulo-ocular reflex function and other functional outcomes are measured to identify the best means to improve the delivery of vestibular rehabilitation. We incorporate ecologically valid outcome measures that address the common symptoms experienced in those with vestibular pathology and multi-sensory impairment. DISCUSSION: The INVENT VPT Trial will directly impact the health care delivery of vestibular rehabilitation in patients suffering from multi-sensory ...
