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

Hip osteoarthritis (OA) affects millions worldwide, yet effective conservative (non-surgical) treatments are still limited. Conventional hip braces cannot reduce painful joint loads associated with contractile forces from flexors and extensors during locomotion. Powered hip exoskeletons could potentially reduce biological hip moments by applying flexion/extension torques, thus attenuating muscle forces that contribute to OA pain. Here, we present a novel task-agnostic controller for a backdrivable hip exoskeleton that relieves hip O A pain across the primary activities of daily life. Inspired by the energy shaping method, this controller utilizes biomechanicsbased components to assist with level walking, ramp and stairs ascent/descent, and sit-to-stand transitions, which can be customized to different populations, like hip OA. In a pilot study with three hip OA participants, the hip exoskeleton holistically reduced pain and perceived difficulty during a multi-activity test (except difficulty of level walking). The exoskeleton also increased hip range of motion during walking, with subject-specific improvements in walking speed. This pilot study suggests that hip exoskeletons may offer a promising new intervention for managing hip O A.
