The objective of this study was to determine the level of agreement between face-to-face hamstring flexibility measurements and free software video analysis in adolescents. Reduced hamstring flexibility is common in adolescents (75% of boys and 35% of girls aged 10). The length of the hamstring muscle has an important role in both the effectiveness and the efficiency of basic human movements, a...

INTRODUCTION Increasing age is a commonly identified predictor of hamstring injury but is not modifiable to reduce injury risk. Why increasing age is a risk factor for hamstring injuries in athletes has not been studied to date. This study aimed to identify potentially modifiable age-related changes that predict hamstring injury in a population of Australian football players. METHODS One hund...

[Purpose] This study assessed the relationship between hamstring length and gluteus maximus (GM) strength with and without normalization by body weight and height. [Subjects and Methods] In total, 34 healthy male subjects volunteered for this study. To measure GM strength, subjects performed maximal hip joint extension with the knee joints flexed to 90° in the prone position. GM strength was no...

STUDY DESIGN Prospective randomized comparison of 2 rehabilitation programs. OBJECTIVES The objectives of this study were to compare the effectiveness of 2 rehabilitation programs for acute hamstring strain by evaluating time needed to return to sports and reinjury rate during the first 2 weeks and the first year after return to sport. A third objective was to investigate the relationship bet...

background: despite the importance of hamstring tendon autograft, one major disadvantage in applying this technique in the surgical reconstruction of anterior cruciate ligament is individual variability in the tendon diameter. hence, the purpose of the present study was to use anthropometric parameters such as gender, height and body mass index to predict 4-strand (quadruple) hamstring tendons ...

Sport Exerc., 9(1), pp. 188-200. The main purpose of the present meta-analysis was to examine the scientific literature on the criterionrelated validity of the toe-touch test for estimating hamstring extensibility. For ...

PURPOSE Are eccentric hamstring strength and between-limb imbalance in eccentric strength, measured during the Nordic hamstring exercise, risk factors for hamstring strain injury (HSI)? METHODS Elite Australian footballers (n = 210) from five different teams participated. Eccentric hamstring strength during the Nordic exercise was obtained at the commencement and conclusion of preseason train...

1. DIAGNOSING AND TREATING ACUTE HAMSTRING INJURIES In BJSM’s all-time favourite podcast, Dutch sports physician Robert-Jan de Vos has Guustaaf Reurink explain his 2014 NEJM paper on the role of platelet-rich plasma in acute hamstring injuries (https://goo.gl/ oGVjA8). They also discuss the value of clinical tests and MRI in acute hamstring injuries, and whether they can predict return to play ...

Hamstring injuries are common forms of muscle strains in athletes but a complete rupture of a proximal hamstring origin is rare. Often there is a considerable delay in diagnosis and stringent treatment because of its rarity, difficulty in clinical diagnosis, and initial attempts of conservative care. We report two cases of acute complete rupture of the proximal hamstring tendons treated with ea...

Abstract: Background: Flexible idiopathic flatfoot is the most common form of flatfoot. First line treatments are parental reassurance and conservative measures. However, surgical treatment may be needed in some cases. A number of surgical techniques with varying results have been described in the literature. Here, we present our clinical and radiological outcomes of calcaneal lengthening osteo...
