Do athletes with hamstring strain injury have shorter muscle fascicles in the injured limb?

Introduction: Previous studies have suggested that a reduced length of the biceps femoris long head (BF) fascicles may increase the risk of hamstring strain injury (HSI). However, it remains unclear whether the BF fascicles of the injured limb are shorter than those of the contralateral limb in athletes with an acute HSI.

Objective: To investigate the between-limb asymmetry of BF fascicle length in amateur athletes with an acute HSI.

The Single Leg Bridge Test does not replace handheld dynamometer hamstring tests in a clinical setting.

Objective: To examine the correlation of Single Leg Bridge Test (SLBT) scores with maximum isometric strength values obtained in handheld dynamometer (HHD) hamstring tests performed in a clinical setting.

Design: Cross-sectional study.

Setting: Physical therapy clinic.

Effect of Nordic Hamstring Exercise Training on Knee Flexors Eccentric Strength and Fascicle Length: A Systematic Review and Meta-Analysis.

Context: Nordic hamstring exercise (NHE) has been widely employed to prevent hamstring strain injuries. However, it is still not clear which adaptations are responsible for the NHE preventive effects.

Objectives: The aim of this study was to investigate the effects of NHE on knee flexors eccentric strength and fascicle length.

Effects of low-level laser therapy on hamstring strain injury rehabilitation: A randomized controlled trial.

Objectives: To evaluate the effects of low-level laser therapy (LLLT) on functional rehabilitation following hamstring strain injury (HSI) in amateur athletes treated with an exercise-based rehabilitation program.

Design: Randomized controlled trial.

Methods: Male athletes (18-40 years old) who sustained HSI were randomized in LLLT or placebo groups.

ACCURACY OF THE FUNCTIONAL MOVEMENT SCREEN (FMS) ACTIVE STRAIGHT LEG RAISE TEST TO EVALUATE HAMSTRING FLEXIBILITY IN SOCCER PLAYERS.

Background: Poor flexibility is considered a risk factor for the hamstring strain injury, and the active straight leg raise (ASLR) test proposed as a part of the Functional Movement Screen™ (FMS™) has been used to assess athletes hamstring flexibility. However, the accuracy of this screening test remains undescribed.

Purpose: To examine the accuracy of the FMS™ ASLR test for assessment of hamstring flexibility in soccer players.

Conservative treatment of Achilles tendon partial tear in a futsal player: A case report.

Achilles tendon is the most commonly injured part in the lower limb, especially in athletes. Treatment options for Achilles tendinopathy and total rupture are well described; however, there is a lack of information regarding treatment protocols for partial tears. Thus, the purpose of this case report was to describe the examination, intervention and outcomes of patient who suffered an acute Achilles tendon partial tear.

Chronic effect of different types of stretching on ankle dorsiflexion range of motion: Systematic review and meta-analysis.

The calf muscles are one of the muscle groups that have the most need for adequate flexibility since they are deeply related to normal lower limb function. When the goal is to increase flexibility, the most commonly used technique is stretching. However, it remains unknown which stretching technique and parameters are the most effective to increase flexibility.
