Sex Differences During Star Excursion Balance Test in Individuals With Chronic Hip-Related Groin Pain.
Article in Journal of sport rehabilitation, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
contextIndividuals with chronic hip-related groin pain display impaired dynamic postural control as measured by the modified star excursion balance test; however, the kinematics and kinetics displayed have not been reported in chronic hip-related groin pain populations. Hip joint kinematics during various tasks differ between males and females with chronic hip-related groin pain; however, few studies have reported trunk kinematics or hip joint loading. We were curious if sex differences exist in trunk, hip, and pelvis kinematics and hip joint loading during the modified star excursion balance test among those with chronic hip-related groin pain.
designCross-sectional.
methodsPatients with chronic hip-related groin pain performed 3 trials of the modified star excursion balance test, reaching in anterior, posteromedial, and posterolateral directions. We used a motion capture system and force plates to capture hip, pelvis, and trunk kinematic and kinetic data. Variables of interest included reach distance, normalized by leg length, and sagittal and frontal plane hip, pelvis, and trunk kinematics and hip joint kinetics at the time of max reach. We used independent t tests or Wilcoxon rank sum tests to assess between-group differences.
resultsCompared with males (n = 11, age = 28 years, body mass index = 25.0 kg/m2), females (n = 17, age = 25 years, body mass index = 22.1 kg/m2) displayed larger hip adduction angle during anterior (12.6° vs 6.1°, P = .048) and posteromedial (1.5° vs -4.6°, P = .043) directions, larger contralateral pelvic drop angle during anterior direction (-1.7° vs 2.3°, P = .014), smaller trunk flexion angle during posteromedial direction (25.8° vs 34.8°, P = .045), and smaller hip flexion moment during posterolateral direction (0.56 vs 0.87 N·m/kg, P = .021). Females and males displayed similar reach distances.
conclusionMovement strategies differ between sexes, with females displaying more hip adduction motion, more contralateral pelvic drop, less trunk flexion motion, and smaller hip flexion moments.
