Wearable sensory-feedback technology has been shown to improve walking in individuals with neurological conditions. This study examined the feasibility and acceptability of procedures to use this technology with older adults who have fear of falling. Recruitment, retention, measurement, and intervention procedures were assessed in a single-center, pre-post, within-subject design study. Older adults with fear of falling were recruited to use wearable sensory feedback technology during a single session conducted in a laboratory setting under the supervision of a physical therapist. Objective measures consisted of gait and posture measures that were made at three time-points during the study session: "baseline," "during" (after training, while wearing the device), and "post" (after the second assessment following removal of the device). Participants ended the session by reporting on their perceptions of the technology. Twenty-four participants were enrolled over a period of 12 months. All enrolled participants were able to complete the study protocol without adverse or unexpected events. Participants provided favorable feedback indicating that it was easy to find a natural rhythm for walking while using the technology. Small to moderate effect sizes were obtained regarding pre-post increases in cadence and double support time and decreases in single limb stance time. Overall, intervention procedures were found to be feasible and acceptable but preliminary data did not point to improvements in gait or balance, i.e., the direction of the effects suggested of pre-post worsening of gait. Areas for improvement were identified that may inform the design and execution of future studies with this patient population.

Establishing the Feasibility of a Tablet-Based Consent Process with Older Adults: A Mixed-Methods Study

Purpose of the Study/UNASSIGNED:This mixed-methods study explored the feasibility and acceptability of using a tablet-based research consent process with adults aged ≥65 years. Design and Methods/UNASSIGNED:In the first phase, focus group participants reported on their perceptions of a tablet-based consent process. In the second phase, older adults were randomized to view either a tablet-based or paper-based consent for a mock clinical trial. Measurements included: time to complete, adverse/unexpected events, user-friendliness, immediate comprehension, and retention at a 1-week delay. Results/UNASSIGNED:Focus group participants (N = 15) expressed interest in the novel format, cautioning that peers would need comprehensive orientation to use the technology. In the randomized pilot (N = 20), retention was 100% and all participants completed the protocol without the occurrence of adverse/unexpected events. Although the participants took longer to complete the tablet-based consent than the paper-based version, user-friendliness, immediate comprehension, and retention of the tablet-based consent were similar to the paper-based consent. Discussion and Implications/UNASSIGNED:The findings suggest that a tablet-based consent process is feasible to implement with older adults and acceptable to this population, but we would underscore that efforts to optimize design of tablet-based consent forms for older adults are warranted.
