Background: Radiographic evaluations are commonly used to determine calcaneal ossification staging throughout pediatric development. Sonographic imaging may offer a less expensive, noninvasive, clinically feasible option for developmental assessments. Here, we assessed (1) inter-rater agreement of radiographic and sonographic children adolescent patients with Sever’s disease (2) between scores. Hypothesis: There would be substantial across raters, measures. Study Design: Retrospective cohort...
ABSTRACT Age is an important factor to consider with Achilles tendon injury, as variability in structure during developmental growth and aging influence lower limb function mobility. However, the overlap structural alterations injury makes it unclear which changes are related age separate from pathology. The objective of this study was determine relationship between healthy tendons. Healthy tendons 389 children adults (8–79 years) were included retrospective analysis. morphology assessed via...
The absence of agreed methods to diagnose Achilles tendinopathy impedes research and clinical practice. This gap results in heterogeneous and/or poorly described study samples, making it challenging apply findings aim this Delphi was define consensus on (1) diagnostic domains; (2) differential diagnoses; (3) conditions requiring further medical attention, when assessing for tendinopathy. We conducted a sequential three-stage process which included: identifying domains, diagnoses attention...
Objective To identify latent subgroups among patients with Achilles tendinopathy, describe patient characteristics and clinical attributes that defined each subgroup, develop a classification model for subgroup membership. Design Cross-sectional study. Methods One hundred forty-five participants (men, n = 73; mean ± SD age, 51 14 years) clinically diagnosed tendinopathy completed baseline evaluation, including demographics medical history, patient-reported outcome measures, exam, tendon...
OBJECTIVES: To (1) evaluate whether the defining characteristics of previously reported Achilles tendinopathy subgroups were reproducible in a cohort with midportion and (2) compare recovery trajectories outcomes. DESIGN: Prospective single study. METHODS: Participants (n = 114; 57 women; age [mean ± standard deviation]: 47 12 years) received Silbernagel protocol evaluated at baseline, 8, 16, 24 weeks. Subgroups identified using mixture modeling. Main effects group time, interaction linear...
Achilles tendinopathy is a common overuse condition. Distinguishing between early- and late-stage may have implications on treatment decisions recovery expectations.To compare the effects of time baseline measures tendon health outcomes among patients with varying symptom durations after 16 weeks comprehensive exercise treatment.Cohort study; Level evidence, 3.Participants (N = 127) were categorized into 4 groups based number months since onset: ≤3 (n 24); >3 ≤6 25); >6 ≤12 18); or >12 60)....
Abstract Background Individuals with end‐stage knee osteoarthritis (OA) walk at a lower intensity (ie, slower step cadence) contributing to worse physical function. Previous literature reports daily counts and sedentary time, little information regarding stepping bouts or cadence. Determining relationships between higher cadence duration clinical outcomes can move the field toward optimal prescription. Objective To quantify activity patterns of individuals OA determine contribution high...
Several factors affect the reliability of anterior drawer and talar tilt tests, including individual clinician's experience skill, ankle knee positioning, muscle guarding.To compare gastrocnemius activity during measurement ankle-complex motion at different positions, secondarily, to a simulated trial guarding.Cross-sectional study.Research laboratory.Thirty-three participants aged 20.2 ± 1.7 years were tested.The was loaded under 2 test conditions (relaxed, guarding) positions (0°, 90°...
Objectives Calcaneal apophysitis (Sever's disease) is an overuse condition caused by repetitive traction stress to the calcaneal apophysis. Whether Achilles tendon morphology altered in this young patient population remains unknown. Therefore, we aimed identify differences between youth athletes diagnosed with and healthy controls. Methods This retrospective chart review included 46 patients (n = 23 Sever's disease, 15F/8M, 12.4 ± 2.3 years old) controls, 13F/10M, 15.9 1.5 who sought care a...
Abstract Tendons enable movement by transferring muscle forces to the skeleton, and athletic performances critically rely on mechanically-optimized tendons. How load-bearing structures of tendon sense adapt physical demands is an open question central importance musculoskeletal medicine human sports performance. Here, with calcium imaging in explants primary cells we characterized how tenocytes detect mechanical determined collagen fiber-sliding-induced shear stress as a key stimulus....
Calcaneal apophysitis and Achilles tendinopathy are common overuse injuries characterised by insidious posterior heel pain with activity. is commonly diagnosed in adolescents, although understudied the adolescent population therefore rarely considered until adulthood. Exercise therapy activity modification have highest level of evidence for treating tendinopathy, while calcaneal treated anecdotal passive treatment or complete rest. It remains unknown whether exercise effective adolescents...
This randomized controlled superiority trial will determine if an 18-month telehealth walking exercise self-management program produces clinically meaningful changes in sustainability compared to attention-control education for veterans living with lower-limb amputation.
PURPOSE: Gait deviations are common in patients with multiple sclerosis (MS) and can increase the risk of falls potential for musculoskeletal pain. This study evaluated relationships between fatigue-induced changes lower extremity kinematics spatiotemporal measures during a Six-Minute Walk Test (6MWT). METHODS: Baseline data from 29 participants ((age 49 ± 12 years, 21F, Expanded Disability Status Scale 1-5.0) MS completed 6MWT. parameters were recorded continuously via inertial measurement...
