The goal of this clinical trial is to determine the effectiveness of perturbation-based balance training (PBT) in preventing unrecovered falls among geriatric patients aged ≥70 years with a prospective fall risk of ≥40%. The study will also assess the safety and feasibility of PBT. The main research questions are:
A total of 396 participants will receive 9 training sessions of either PBT or conventional treadmill training and will attend an assessment before and after the intervention, as well as 6 and 12 months follow up. Falls will be documented throughout the entire study period using calendars, telephone interviews, and proxy information. The primary outcome, unrecovered falls, will be recorded after the end of the intervention until 12 months follow up.
Falls are common and the leading cause of injuries among older adults, but falls may be attenuated by the promising and time-efficient intervention called perturbation-based balance training (PBT). The aim of the TRAIL-study is to confirm the effectiveness of a treadmill PBT protocol for preventing unrecovered falls in geriatric patients with and without cognitive impairment. This study is designed as a confirmatory, multicenter, assessor-blinded, randomized controlled study. The 396 geriatric patients aged ≥70 years with ≥40% prospective fall risk and being capable of walking ≥70 m in a 2-Minute Walk Test will receive 9 sessions of PBT on a treadmill (intervention) or a conventional treadmill training (control group; CTT).
Outcome assessments will be performed shortly after the intervention interval as well as 6 and 12 months thereafter. The primary outcome is defined as unrecovered falls (defined as falls in which persons who fell are unable to get up independently) within 12-month follow-up. Falls are documented over at least 12 months using calendars, telephone interviews, and proxy information. Secondary outcomes include mobility, balance performance, concerns about falling, physical activity and capacity, stepping responses, health-related quality of life, cognitive functioning, mobility, reactive dynamic balance and training acceptability of PBT. The study will be accompanied by a patient advisory board and an expert advisory board and focus groups will be conducted to involve the target group.
Based on pilot studies and the available literature, we expect a ≥50% reduction of unrecovered falls during the following year in the intervention group (PBT) compared to the control group (CTT).

| Conventional Treadmill Walking (CTT) | Other | The CTT serves as a comparison to PBT. It involves standard treadmill walking without perturbations on the same treadmill. This intervention is conducted over the same defined period as PBT (3-6 weeks), with a matched frequency and exercise time compared to the PBT group for consistency. Participants are secured with safety harnesses while walking. |

| Perturbation-Based Balance Training (PBT) | Other | Overall, 9 training sessions with different objectives and progression regarding perturbation directions, predictability, and intensity will be conducted within 3-6 weeks. During the initial sessions, familiarizing participants with the treadmill and establishing their individual walking pace will be focused. Pace can be individually adjusted in each training session. Participants are secured with safety harnesses while walking. |

Physical activity will be measured over 7 days using a body-fixed inertial measurement unit (AX6, Axivity Ltd., Newcastle, UK) , which will be placed at lumbar level (L5) of the participant. The sensor measures linear acceleration data in 3 dimensions in combination with angular data. From these data, besides others, time spent with physical activity, steps as well as time spent in the supine sitting or standing position can be determined and reported. Data will be used to describe the participants and to report falls per physical activity.
