Association Between Changes in Shoulder Strength and Self-Reported Shoulder Symptoms in Patients With Hypermobility Following 16-Weeks of High-Load or Low-Load Exercise: A Secondary Analysis of an RCT.
Trial report in Physiotherapy research international : the journal for researchers and clinicians in physical therapy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03869307 (Shoulder Exercises in Patients With Hypermobility Spectrum Disorder and Long-lasting Shoulder Symptoms), which is not on this 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.

Abstract
background and purposeHypermobility Spectrum Disorder (HSD) is a common musculoskeletal condition that impairs function and quality of life. While exercise therapy has shown to improve outcomes, treatment standardisation is lacking and the relationship between strength and symptoms remains unclear. Therefore, our aim was to investigate the association between changes in shoulder strength and self-reported shoulder function, pain, and perceived effect in patients with HSD and shoulder symptoms.
methodsThis is a secondary analysis of a randomised controlled trial. Data from 76 participants (58 women; median age 35.5) were included. Primary outcomes were percentage change in relative strength (Nm/kg) measured in external rotation, internal rotation, and scaption, the Western Ontario Shoulder Instability Index (WOSI), the Numerical Pain Rating Scale (NPRS) and the Global Perceived Effect: Physical domain (GPEP). Secondary outcomes were achieving the Minimal Clinically Important Difference (MCID) in shoulder function and pain. Covariates were age, sex, Body Mass Index, hand dominance, previous shoulder dislocation, mechanical shoulder symptoms, and assigned intervention group.
resultsIncreasing strength in external rotation and scaption were linearly associated with an improvement in shoulder function (WOSI adjusted -3.5 (95% CI -5.9; -1.1), and WOSI adjusted -2.6 (95% CI -4.6; -0.6) respectively), while scaption strength was associated with a reduction in shoulder pain (NPRS -0.01 (95% CI -0.02; 0.00)). Improvement in external rotation and scaption were associated with higher odds of reporting an important improvement measured for every 10% increase in strength (adjusted OR 1.18 (95% CI 1.00; 1.38) and 1.30 (95% CI 1.07; 1.59), respectively). DISCUSSION: Increased shoulder strength may be associated with improved outcomes in patients with HSD and persistent shoulder symptoms although our findings suggest limited clinical relevance. Further research is needed to understand the relationship between strength and symptom relief.
