Reliable assessment of biomechanical and clinical outcomes is essential to distinguish true clinical change from measurement error and for guiding rehabilitation and return-to-running decisions. However, evidence for the reliability of commonly used measures in MTSS is limited. # Purpose To determine the test-retest reliability and minimal detectable change (MDC) of common biomechanical and clinical outcomes in runners with MTSS. # Study design Test-retest reliability study. # Methods Twenty-two runners with MTSS were assessed twice, three days apart, by the same examiner. Biomechanical outcomes included center of pressure (COP) trajectory during running and cross-sectional area (CSA) and strength of the flexor hallucis longus (FHL) muscle. Clinical outcomes included linear pain distance on palpation along the posteromedial tibial border, and pain level reported using a visual analog scale (VAS). Paired t-tests were used to analyze the differences between sessions. Intraclass correlation coefficients (ICC<sub>3,k</sub>) were calculated to assess reliability. The standard error of measurement (SEM), the MDC and the Bland-Altman plot were calculated. # Results No significant differences between sessions were observed for any outcome. Test-retest reliability was good to excellent for COP (ICC<sub>3,1</sub>=0.92), linear pain distance on palpation along the posteromedial tibial border (ICC<sub>3,1</sub>=0.94), CSA (ICC<sub>3,3</sub>=0.82), and FHL strength (ICC<sub>3,3</sub>=0.88). SEM and MDC value were 0.86% and 2.38% for COP, 0.77 cm and 2.12 cm for linear pain distance on palpation along the posteromedial tibial border, 0.23 cm² and 0.63 cm² for CSA, and 0.54 kg and 1.49 kg for FHL strength. The Bland-Altman plot shows the agreement of all variables. # Conclusion Common biomechanical and clinical outcomes in runner with MTSS demonstrated good to excellent test-retest reliability.

Accurate evaluation of the RA is therefore critical for both diagnostic and rehabilitative purposes. Musculoskeletal ultrasound (MSKUS) has emerged as a valuable imaging modality for assessing the structure and function of the RA muscle. Offering real-time, dynamic visualization without ionizing radiation, MSKUS enables clinicians and researchers to examine muscle morphology, thickness, echogenicity, and contractile behavior with high precision.

Recent advances in MSKUS have expanded its role in evaluating abdominal wall musculature, particularly in populations ranging from athletes and postoperative patients to postpartum women.

Post-ACL reconstruction, athletes were measured for YBT anterior reach distance at three months and isokinetic knee extensor strength at six months; their respective LSIs were calculated. Cutoff points for anterior reach distance LSI at three months postoperatively to identify if knee extensor strength would be achieved at six months postoperatively were determined using a minimum p-value approach, and phi coefficients; sensitivity and specificity were also calculated. # Results Data from 90 patients (53% female, age: 21(12.5) years) who met the inclusion criteria were analyzed. The cutoff point of 90% for the anterior reach distance LSI yielded the lowest p-value and highest chi-square value (p=0.010, chi-square value=6.553). At the cutoff point, a significant association was found between the anterior reach distance LSI at three months and the knee extension strength LSI at six months (φ=0.270), with a sensitivity of 38.1% and a specificity of 88.9%. # Conclusions Patients with an anterior reach distance LSI of <90% at three months postoperatively are at higher risk of not achieving a knee extension muscle LSI of 90% at six months. Anterior reach distance LSI can be safely measured daily during the early postoperative phase; therefore, it may help guide postoperative planning for rehabilitation until return-to-sport discussions begin.</p><p><strong>Level of evidence: </strong>3.</p>","PeriodicalId":47892,"journal":{"name":"International Journal of Sports Physical Therapy","volume":"20 10","pages":"1448-1456"},"PeriodicalIF":2.1,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12490895/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145233766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
