A pull function attachment to manual wheelchairs: a case report on usability and shoulder pain in people with spinal cord injury.

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.
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
introductionShoulder pain mostly due to high biomechanical load of the anterior-shoulder musculature is prevalent among manual wheelchair users with spinal cord injury or disorder (SCI/D). This case study showcases a novel pull-function attachment to the wheelchair that reverses the propulsion motion by pulling rather than pushing the wheelchair. Additionally, the study reports its preliminary usability and impact on shoulder pain. CASE PRESENTATION: Four individuals with SCI/D (median age: 33; 1 female) used the novel pull-function attachment to the manual wheelchair for six weeks. Usability (System Usability Scale; ranging from 1 = 'strongly disagree' to 5 = 'strongly agree') and daily usage time were assessed. Shoulder pain intensity was explored before and after the six weeks using the Wheelchair User's Shoulder Pain Index. Median usability scores were ≥3.0 for 5/6 items, indicating high usability of the assistive technology. Shoulder pain intensity was reduced in all participants at the post-test (median change: -6.3), with the change in shoulder pain exceeding the minimal detectable change for 2/3 participants. DISCUSSION: The results of this case study suggest high usability of the pull-function attachment to the wheelchair. The decreases in shoulder pain intensity reported following six weeks of use were noticeable and may have clinical relevance. This novel assistive technology that enables forward propulsion by pulling rather than pushing the wheelchair may therefore have the potential to reduce shoulder pain in manual wheelchair users with SCI/D.
