1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundFalls in older adults increase the risk of mobility loss. Proper understanding of gait mechanisms related to falls may provide novel solutions for maintaining mobility in older adults. RESEARCH QUESTION: Identify fall-related gait patterns through analyzing alterations in gait parameters to walk faster than usual pace in older adults.

methodsA Total of 519 participants (mean age = 73.12 years; 51.05 % female), including non-fallers (n = 396) and fallers (n = 123), aged 60-96 years were assessed in the Baltimore Longitudinal Study of Aging. Participants completed gait assessments at both usual and fast paces. Range of motions (ROM) for the hip, knee, and ankle joint in the sagittal plane and hip abductor ROM during normal and fast pace gait were measured by 3D motion capture system (Vicon 612). For all gait variables, percentage-changes (PC; (((fast-walking_parameter - usual-walking_parameter) /usual-walking_parameter)*100)) was calculated. Associations of PC for gait speed and PC for other gait parameters were compared between fallers and non-fallers.

resultsCompared to non-fallers, fallers walked with shorter stride, elongated double support time and shorter knee ROM in the faster pace walk (p = 0.044, p = 0.019, and p = 0.036, respectively). PCs of all gait related variables were significantly associated with PC of gait speed in non-fallers (ps < 0.005), while in the fallers, only PC for stride length, cadence, and hip ROM were associated with PC for gait speed (ps < 0.001). SIGNIFICANCE: Among non-fallers related PC for gait speed was associated with PC across gait parameters suggesting the use of similar biomechanical approaches in usual and fast gait. Compared to non-fallers, fallers demonstrated different mechanisms of transition from usual to fast gait. Evaluating speed-up strategies could provide insight into subtle yet important gait modifications in apparently well-functioning older adults that would help identify individuals at high risk of falling.
