The feasibility study is designed to assess the feasibility of conducting a group yoga intervention and acquiring neuroimaging data in adults with chronic brain injury.
In the United States in 2014, nearly 2.9 million individuals sustained traumatic brain injuries that resulted in emergency department visits, hospitalizations, and death. Traumatic brain injury (TBI) is caused by trauma, or an external force that creates rapid acceleration and deceleration of the brain within the skull creating lasting neurophysiological dysfunction. Although there are many effective treatment strategies for the weeks and months post-injury (e.g. intensive, multi-disciplinary in-patient rehabilitation), millions of individuals are living with residual disability from brain injury following discharge to home. This residual disability can include significant social, cognitive, emotional, and physical impairment. To date, there are limited strategies for treating the residual deficits of chronic brain injury. One such physical deficit is balance impairment, which is associated with increased fall risk, reduced community integration, and decreased quality of life. The use of intensive, holistic rehabilitation may be effective for improving balance and other impairments in individuals with chronic brain injury. Yoga, a holistic treatment option, is thought to be more therapeutic than traditional exercise because of the integration of the mind, body, and spirit. Further, yoga can be modified to accommodate individual abilities and needs. And, unlike formal rehabilitation, yoga does not need to be approved by insurance or prescribed by a physician and adapted yoga is available in the community. Thus, yoga is readily available, so long as yoga instructors are trained to appropriately modify activities. Recently, the research team found that group yoga improved balance performance in seven adults with chronic brain injury. This study is designed to test the feasibility of conducting another group yoga intervention and acquiring neuroimaging data before and after the intervention.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Group Yoga | Experimental | Yoga includes breath work (pranayama), gentle stretching and holding of postures (asanas), and meditation (dhyana). Modifications/adaptations are incorporated so all participants can successfully complete the yoga intervention. Yoga is delivered in a standardized progression, including: focused, slow breath with movement and breathwork throughout every session; mantras, progressively challenging yoga postures (sitting, standing, and floor); and meditation |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Group Yoga | Behavioral | Yoga is delivered as described in an earlier section in a group format. Classes are an hour in duration and occur once per week for 8 weeks, and they are led by an adaptive yoga specialist. |
| Measure | Description | Time Frame |
|---|---|---|
| Change in Balance Performance from Baseline to Post-Intervention Timepoint | Six balance tasks, adapted from the Berg Balance Scale, were administered with simultaneous functional near infrared spectroscopy (see secondary outcomes). Each balance task was evaluated using Functional Independence Measure (FIM) scoring, ranging from 0 (dependent, unable to do) to 7 (independent, able to do without help). A composite score was generated by averaging FIM scores from each balance task. Change in balance was quantified as the difference in the post-intervention balance composite score and the baseline balance composite score. | Baseline was ~ 2 weeks before the start of group yoga; Post-Intervention was after the last group yoga class, which was 12-13 weeks after baseline assessment. |
| Change in Executive Functioning from Baseline to Post-Intervention Timepoint | Executive function was assessed with a self-report measure, the Behavior Rating Inventory of Executive Function - Adult Version. The BRIEF-A includes nine clinical scales: inhibit, self-monitor, plan/organize, shift, initiate, task monitor, emotional control, working memory and organization of materials. Items are self-rated using a three-point frequency scale (1 = never; 2=sometimes; 3=often). These items contribute to two broad indexes, behavioral regulation and metacognition, which are combined for a summary score. Raw scores are transformed into a T-score. Higher T scores reflect more reported problems and T scores at or above 65 are considered clinically significant. | Baseline was ~ 2 weeks before the start of group yoga; Post-Intervention was after the last group yoga class, which was 12-13 weeks after baseline assessment. |
| Measure | Description | Time Frame |
|---|---|---|
| Resting State Functional Magnetic Resonance Imaging (rs-fMRI) - Feasibility Benchmark of Safety at Baseline | The feasibility of safely acquiring rs-fMRI data was defined as the following: Detect 100% MRI contraindications during screening. Sustain zero instances of adverse events (e.g. pain or significant anxiety) or falls during data acquisition. | Baseline was ~ 2 weeks before the start of group yoga. |
