Stolpern üben, um nicht zu fallen: Wie reaktives Gleichgewichtstraining funktioniert

BACKGROUND: Falls are a leading cause of injuries in older adults, often resulting from slipping and tripping. Perturbation-based balance training (PBT) applied on treadmills is an emerging task-specific approach to falls prevention but standardized training protocols are lacking. This review presents an overview of PBT protocols on treadmills, their theoretical justification and proposes recommendations for standardized reporting. METHODS: A systematic search was conducted in PubMed, Embase, Web of Science, CINAHL, CENTRAL and Clinical Trials Registration on May 9, 2025 to identify RCTs, pilot studies, study protocols and trial registrations on treadmill-based PBT for falls prevention in healthy older adults or those diagnosed with stroke, Parkinson’s disease or multiple sclerosis. Studies were screened by two independent researchers. Data on general and PBT specific training parameters as well as the justification for those parameters were narratively synthesized. RESULTS: 1253 studies were identified. The eligibility criteria were met by 69 publications referring to 36 research projects. In total, 1928 participants were included, with 950 participants in the PBT groups. The training periods lasted from a single session to 12 weeks, including one to three sessions per week, each from 20 to 60 min. During standing and walking, from 24 up to 160 unannounced perturbations were induced, consisting of treadmill belt acceleration and deceleration as well as lateral displacements.

Falls are a leading cause of injury-related hospitalization, morbidity, and mortality in older adults, with impaired postural control serving as a key predictor of fall risk. The triceps surae, and particularly the soleus, plays a central role in maintaining upright stance by generating continuous plantarflexion moments that stabilize the body's center of mass. This mini-review summarizes evidence for the neuromechanical contributions of the soleus to postural stability and how these functions decline with age. Mechanically, the soleus acts as a brace for balance, providing sustained torque through fatigue-resistant type I fibers and a compliant Achilles tendon that buffers perturbations and contributes to ankle stiffness. Age-related reductions in tendon stiffness and rate of torque development compromise these stabilizing properties, increasing fall susceptibility. When passive stiffness is insufficient, the soleus compensates through active contraction, trading energy cost of activation for joint stability. Reflexively, the soleus serves as a stabilizer of balance through strong coupling to spinal, cutaneous, vestibular, and transcortical pathways that rapidly adjust muscle activation in response to perturbations. These reflex mechanisms also degrade with aging, leading to delayed, less adaptable responses. Together, age-related mechanical and neural deterioration reduce the soleus' ability to sustain balance and contribute to fall recovery. Preserving soleus strength, ten

<h4>Background</h4>Falls are a major health concern among older adults, leading to injury, reduced independence, and increased healthcare cost. Reactive balance training can reduce fall risk, but barriers such as fear, joint discomfort, and harness burden limit its use - barriers that training in aquatic environment  may help overcome.<h4>Objective</h4>To design an aquatic reactive balance training (AquaReBal) program for older adults, integrating end-user perspectives to enhance safety, accessibility, and engagement.<h4>Methods</h4>Using a participatory design approach grounded in Participatory Action Research principles, we engaged three older adult partners, physiotherapists, and researchers in iterative phases including literature review, stakeholder consultations, practical pool sessions, and feedback meetings. Data collected through online meetings, surveys, field notes, and observations were reviewed using an inductive qualitative content analysis approach to inform iterative refinement of the intervention, following the Guidance for Reporting Involvement of Patients and the Public 2 framework.<h4>Results</h4>Three older adult partners and a multidisciplinary team co-designed the AquaReBal protocol through two participatory design sessions, one practical pool session, and two internal team sessions. Key recommendations from partners included using a vest instead of a hip belt for perturbations, addressing pool depth visibility, and creating an introductory package with
