Does joint hypermobility exacerbate altered landing and jumping strategies in adolescents with fibromyalgia syndrome compared to controls?

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
backgroundJoint hypermobility is common in children and persists in various genetic and connective tissue disorders, including conditions characterized by chronic musculoskeletal pain (i.e. Juvenile Fibromyalgia Syndrome), which involves movement dysfunction. It is unclear if joint hypermobility contributes to this dysfunction. This study investigated whether generalized joint hypermobility is associated with altered landing/jumping biomechanics in adolescents with juvenile fibromyalgia syndrome compared to controls.
methodsAdolescents with juvenile fibromyalgia syndrome and hypermobility (n = 17), juvenile fibromyalgia syndrome without hypermobility (n = 17), and non-hypermobile controls (n = 17) performed a landing/jumping task while 3D-motion capture and ground reaction force data were collected. Timewise data were compared using statistical parametric mapping.
findingsBoth groups with juvenile fibromyalgia syndrome exhibited altered lower extremity biomechanics compared to controls, including increased sagittal hip and ankle kinematics (P < 0.0001), ∼25 % reduced sagittal knee and ankle kinetics (P ≤ 0.038) and ∼ 2.5× greater knee internal rotation (P < 0.0001) during landing/jumping, as well as ∼75 % and ∼ 20 % reduced ground reaction force during initial landing and jumping (P < 0.0001), respectively. Both groups with juvenile fibromyalgia syndrome, demonstrated 17-26 % reduced landing depth (P < 0.0001;d ≤ 1.79) and 26 % reduced jump height (P ≤ 0.01;d ≤ 0.86), indicating inefficient momentum absorption.
interpretationAltered biomechanics observed in both groups with juvenile fibromyalgia syndrome may reflect an attempt to avoid pain. While hypermobility did not significantly differentiate the groups with juvenile fibromyalgia syndrome overall, it was associated with more inefficiencies. This study highlights the need for hypermobility-specific movement assessments to understand movement-associated pain, strength, and kinesthetics to improve early identification and treatment of youth with hypermobility at risk for chronic pain and functional limitations.
