Objectives: To examine the effects of anterior load carriage on dynamic sagittal spinal alignment during the gait cycle in younger (<65 y) and older (≥65 y) adults. Design: Cross-sectional study of 47 participants aged 20–80 years categorized as young and older adults. Participants walked at self-selected speeds with and without a 4.5 kg anterior chest load. Whole-body kinematics were recorded using a 19-camera infrared motion capture system. Outcome measures included lumbar lordosis (LL), thoracic kyphosis (TK), trunk inclination (TI), sagittal trunk shift (STS), and pelvic tilt (PT). Gait-cycle–dependent differences were analyzed using statistical parametric mapping. Results: The mean age was 41 years in young adults (n=28) and 70 years in older adults (n=19). Anterior load carriage increased LL during portions of the gait cycle and reduced TI throughout the entire gait cycle. Younger adults demonstrated greater LL and lower TI than older adults. A significant age-by-load interaction for TI was observed during portions of the gait cycle. Conclusions: Anterior load carriage alters spinal alignment by increasing LL and reducing TI during walking, with distinct age-related patterns. These results provide valuable reference data and a foundation for future studies on load management and ergonomic interventions across the adult lifespan.

There is an increased clinical use of elbow orthoses. It is important to consider patient experiences in their use. Patient-reported outcome measures (PROMs) serve as essential tools for gathering patient perspectives. This review provides a comprehensive list of PROMs used in clinical trials of elbow orthoses, and documents their properties, uses, and quality. A systematic literature search across PubMed, Scopus, Embase, Cumulative Index to Nursing and Allied Health Literature, and Web of Science identified 31 clinical trials of elbow orthoses that used PROMs as outcome measures. Subsequently, manual searches were conducted to report on each PROM's characteristics. A total of 15 different PROMs were used as outcome measurements in clinical trials that used an elbow orthosis as an intervention for 11 different conditions. Researchers can use this review to aid in making informed decisions about which PROMs to use for future clinical trials.
