BACKGROUND This study was aimed at quantifying superoinferior and mediolateral skin distraction over the spine's midline for the purpose of designing a unique surface marker for use in a study originally proposed by Wojtys and Ashton-Miller. It was also aimed at testing the null hypotheses H(01): There is no difference in the amount of skin distraction between hamstring normal and hamstring tig...

This study aimed to determine: (a) the spatial patterns of hamstring activation during the Nordic hamstring exercise (NHE); (b) whether previously injured hamstrings display activation deficits during the NHE; and (c) whether previously injured hamstrings exhibit altered cross-sectional area (CSA). Ten healthy, recreationally active men with a history of unilateral hamstring strain injury under...

Open surgical management of proximal hamstring tears appear to yield superior outcomes versus non- operative, however, little is known about the efficacy performing an endoscopic repair. Therefore, purpose this study was evaluate repair (ePHR). Specifically, we evaluated: (1) functional and subjective outcomes; (2) effectiveness treatment (pre-to-post-operative change); (3) complications; (4) a...

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...

The present study examined site-specific hamstring muscles use with functional magnetic resonance imaging (MRI) in elite soccer players during strength training. Thirty-six players were randomized into four groups, each performing either Nordic hamstring, flywheel leg-curl, Russian belt or the hip-extension conic-pulley exercise. The transverse relaxation time (T2) shift from pre- to post-MRI w...

STUDY DESIGN Case report. BACKGROUND Proximal hamstring tendinopathy is a relatively uncommon overuse injury seen in runners. In contrast to the significant amount of literature guiding the evaluation and treatment of hamstring strains, there is little literature about the physical therapy management of proximal hamstring tendinopathy, other than the general recommendations to increase streng...

The purposes of this study were to document relative activation intensities of the hamstrings and gluteus maximus during 4 eccentric hamstring strengthening exercises and to assess the effects of a short-term strengthening program comprised of these exercises on knee flexor strength and the length-tension relationship. Twelve healthy subjects participated in this study. Electromyographic (EMG) ...

Recurrent hamstring injuries are a major problem in sports such as football. The aim of this paper was to use a clinical example to describe a treatment strategy for the management of recurrent hamstring injuries and examine the evidence for each intervention. A professional footballer sustained five hamstring injuries in a relatively short period of time. The injury was managed successfully wi...

BACKGROUND Harvested hamstring tendon length has received scant attention in published anterior cruciate ligament (ACL) reconstruction literature, yet length can limit the ability to increase graft diameter by folding the tendon over more than once. Indeed, some ultrashort tendons may be too short to yield a clinically useful graft after being folded over just once. Ultimately, the total length...

PURPOSE OF THE STUDY The aim of the study is to present a comparison of short-term results of doubleversus single-bundle anatomical reconstruction of the anterior cruciate ligament (ACL) using hamstring endons and their fixation with absorbable interference
