Risk factors for acute injuries and overuse syndromes of the shoulder in amateur triathletes - A retrospective analysis.

ABSTRACT:

Objectives

To investigate the prevalence of shoulder-related acute and overuse injuries in triathletes and examine the role of possible risk factors, in order to identify potential preventive measures.

Methods

We performed a retrospective epidemiologic study of 193 amateur triathletes between June and August 2013 and evaluated their competition and training habits, as well as the presence of acute and overuse injuries of the shoulder sustained during the past 12 months. Contingency tables were analyzed using Pearson's chi-squared test. Normally distributed data were compared with the independent samples t-test, while non-parametric analyses were performed with the Mann-Whitney U test. Binary logistic regression was used to identify important predictors of injuries.

Results

12 participants (6%) sustained acute injuries and 36 athletes experienced an overuse injury. The acute injury rate amounted to 0.11 per 1000 hours of training and the overuse injury rate to 0.33 per 1000 hours of training. There was no association between athletes' age, height, weight, BMI, a history of shoulder complaints or triathlon experience in years and acute or overuse injuries. Male athletes had a trend for sustaining more acute injuries then female athletes (8% vs. 2%, p = 0.079). Athletes with acute injuries spent a significantly higher amount of time per week doing weight training (p = 0.007) and had a trend for a higher weekly duration of cycling training (p = 0.088). Athletes with overuse injuries participated in a significantly higher number of races compared to athletes without overuse injuries (p = 0.005). The regular use of paddles was associated with a significantly higher rate of overuse injuries (24% vs. 10%, p = 0.014).

Conclusion

The regular use of paddles during swimming training appears to be a risk factor for the development of overuse injuries, while an increased duration of weight and cycling training seems to be associated with a higher rate of acute injuries.

Project description:BackgroundThe physical examination is one of the cornerstones of the diagnostic process in patients with acute shoulder injuries. The discriminative properties of a given examination test depend both on its validity and reliability. The aim of the present study was to assess the interrater reliability of 13 physical examination manoeuvres for acute rotator cuff tears in patients with acute soft tissue shoulder injuries.MethodsIn a large walk-in orthopaedic emergency department, 120 consecutive patients ≥40 years of age were included in a diagnostic study. Patients who had follow-up within three weeks of an acute shoulder injury without fracture on radiographs were eligible. Four emergency department physicians participated as examiners. In a subset of 48 patients, the physical examination tests were performed by two physicians, randomly chosen by their work rotation. The physicians were blinded to the findings of each other and the results of the ultrasound screening. The interrater reliability was assessed by Cohen's kappa, intraclass correlation coefficient (ICC), standard error of measurement (SEM) and Bland-Altman plots depending on whether the examination test result was registered as a binary, ordered categorical or continuous numerical variable.ResultsThe median age was 55.5 years, 46% were female. Twenty-seven percent had a rotator cuff full-thickness tear on ultrasound screening; all but one involved the supraspinatus tendon. Cohen's kappa for binary tests ranged from excellent to fair. Excellent agreement (kappa > 0.8) was found for the inability to abduct above 90° and abduction strength. External rotation strength expressed substantial agreement (kappa 0.7). The lowest scores were registered for Hawkins` test and the external rotation lag sign (kappa 0.25 and 0.40, respectively). The ICCs for active range of abduction and external rotation were 0.93 (0.88-0.96) and 0.84 (0.72-0.91), whereas the SEM was 15 and 9, respectively.ConclusionsThe results indicate that examination manoeuvres assessing abduction and external rotation range of motion and strength are more reliable than manoeuvres assessing pain in patients in the acute phase of traumatic shoulder injury. The poor agreement observed is likely to limit the validity in the present setting of two commonly used tests.Trial registrationThe Norwegian Regional Ethics Committee South East ( 2015/195 ).

Project description:BackgroundRunning overuse injuries (ROIs) occur within a complex, partly injury-specific interplay between training loads and extrinsic and intrinsic risk factors. Biomechanical risk factors (BRFs) are related to the individual running style. While BRFs have been reviewed regarding general ROI risk, no systematic review has addressed BRFs for specific ROIs using a standardized methodology.ObjectiveTo identify and evaluate the evidence for the most relevant BRFs for ROIs determined during running and to suggest future research directions.DesignSystematic review considering prospective and retrospective studies. (PROSPERO_ID: 236,832).Data sourcesPubMed. Connected Papers. The search was performed in February 2021.Eligibility criteriaEnglish language. Studies on participants whose primary sport is running addressing the risk for the seven most common ROIs and at least one kinematic, kinetic (including pressure measurements), or electromyographic BRF. A BRF needed to be identified in at least one prospective or two independent retrospective studies. BRFs needed to be determined during running.ResultsSixty-six articles fulfilled our eligibility criteria. Levels of evidence for specific ROIs ranged from conflicting to moderate evidence. Running populations and methods applied varied considerably between studies. While some BRFs appeared for several ROIs, most BRFs were specific for a particular ROI. Most BRFs derived from lower-extremity joint kinematics and kinetics were located in the frontal and transverse planes of motion. Further, plantar pressure, vertical ground reaction force loading rate and free moment-related parameters were identified as kinetic BRFs.ConclusionThis study offers a comprehensive overview of BRFs for the most common ROIs, which might serve as a starting point to develop ROI-specific risk profiles of individual runners. We identified limited evidence for most ROI-specific risk factors, highlighting the need for performing further high-quality studies in the future. However, consensus on data collection standards (including the quantification of workload and stress tolerance variables and the reporting of injuries) is warranted.
