Much controversy exists regarding the potential advantages and disadvantages of various graft choices for anterior cruciate ligament reconstruction. Advocates of hamstring autografts often cite the limited apparent morbidity associated with semitendinosus or semitendinosus and gracilis harvest, including evidence that hamstring tendons may regenerate after harvest. In this article, we attempt t...

[Purpose] This study developed a pelvic wedge and belt and investigated their effects on the selective activation of medial and lateral hamstring muscles during knee flexion. [Subjects and Methods] Nine adults were enrolled. The participants performed exercises without and with the pelvic wedge and belt, and the electromyographic activities of the medial and lateral hamstring muscles were recor...

Introduction: Since crown lengthening surgery could be accompanied by stress, pain and discomfort, knowledge about its predisposing factors could reduce the demands for such surgery.The aim of this study was to identify the most important indications of crown lengthening surgery in order to present new ideas to clinicians on how to reduce the need for this surgery. Methods: This cross-sectio...

[Purpose] This study compared the efficacy of passive and active stretching techniques on hamstring flexibility. [Subjects] Fifty-four healthy young subjects were randomly assigned to one of three groups (2 treatment groups and 1 control group). [Methods] Subjects in the passive stretching group had their knees extended by an examiner while lying supine 90° of hip flexion. In the same position,...

BACKGROUND Hamstring strain and anterior cruciate ligament injuries are, respectively, the most prevalent and serious non-contact occurring injuries in team sports. Specific biomechanical and neuromuscular variables have been used to estimate the risk of incurring a non-contact injury in athletes. OBJECTIVE The aim of this study was to systematically review the evidences for the effectiveness...

Hamstring injuries are the most prevalent injury in Australian Rules football. There is a lack of evidence based literature on the treatment, prevention and management of hamstring injuries, although it is agreed that the etiology is complicated and multi-factorial. We present two cases of hamstring injury that had full resolution after spinal manipulation and correction of lumbar-pelvic biomec...

BACKGROUND Hamstring injuries are the second most common injury causing missed days in professional baseball field players. Recent studies have shown the preventive benefit of eccentric conditioning on the hamstring muscle group in injury prevention. Specifically, Nordic-type exercises have been shown to decrease the incidence of acute hamstring injuries in professional athletes. PURPOSE This...

QUESTION Does eccentric muscle training of hamstring muscles reduce the rate of hamstring injuries in male soccer players? DESIGN Cluster randomised, controlled trial with concealed allocation. SETTING The 5 top men's soccer divisions in Denmark. PARTICIPANTS First team squad soccer players from teams in the top 5 national soccer divisions were included. Players who joined a team after th...

BACKGROUND Although equinus is more common in cerebral palsy (CP), the prevalence of calcaneal gait (CG) has been reported at more than 30% among patients with CP, even in the absence of prior surgical intervention. The goal of this study was to identify patient characteristics predictive of the development of CG in patients without prior triceps surae lengthening. METHODS Gait data were revi...
