Acute hamstring injuries in Swedish elite sprinters and jumpers: a prospective randomised controlled clinical trial comparing two rehabilitation protocols.

Background: Hamstring strain is a common injury in sprinters and jumpers, and therefore time to return to sport and secondary prevention become of particular concern.

Objective: To compare the effectiveness of two rehabilitation protocols after acute hamstring injury in Swedish elite sprinters and jumpers by evaluating time needed to return to full participation in the training process.

Study Design: Prospective randomised comparison of two rehabilitation protocols.

Acute hamstring injuries in Swedish elite football: a prospective randomised controlled clinical trial comparing two rehabilitation protocols.

Background: Hamstring injury is the single most common injury in European professional football and, therefore, time to return and secondary prevention are of particular concern.

Objective: To compare the effectiveness of two rehabilitation protocols after acute hamstring injury in Swedish elite football players by evaluating time needed to return to full participation in football team-training and availability for match selection.

Study Design: Prospective randomised comparison of two rehabilitation protocols.

Total proximal hamstring ruptures: clinical and MRI aspects including guidelines for postoperative rehabilitation.

The aim of this article is to provide a state-of-the-art review for treatment of acute, total proximal hamstring tendon ruptures. For total proximal hamstring tendon ruptures, early (<2-3 w) surgical refixation minimizes muscle atrophy and facilitates a somewhat predictable time course for healing and rehabilitation. A postoperative rehabilitation program is detailed that has been used by one physical therapist for the past 7 years on over 200 patients with surgical repair for total proximal hamstring tendon rupture.

Proximal hamstring strains of stretching type in different sports: injury situations, clinical and magnetic resonance imaging characteristics, and return to sport.

Background: Hamstring strains can be of at least 2 types, 1 occurring during high-speed running and the other during motions in which the hamstring muscles reach extreme lengths, as documented for sprinters and dancers.

Hypothesis: Hamstring strains in different sports, with similar injury situations to dancers, also show similarities in symptoms, injury location, and recovery time.

Study Design: Case series (prognosis); Level of evidence, 4.

Acute first-time hamstring strains during slow-speed stretching: clinical, magnetic resonance imaging, and recovery characteristics.

Background: Hamstring strains can be of 2 types with different injury mechanisms, 1 occurring during high-speed running and the other during stretching exercises.

Hypothesis: A stretching type of injury to the proximal rear thigh may involve specific muscle-tendon structures that could affect recovery time.

Study Design: Case series (prognosis); Level of evidence, 2.

Acute first-time hamstring strains during high-speed running: a longitudinal study including clinical and magnetic resonance imaging findings.

Background: Hamstring muscle strain is one of the most common injuries in sports. Still, knowledge is limited about the progression of clinical and magnetic resonance imaging characteristics and their association with recovery time in athletes.

Hypothesis: Knowing the anatomical location and extent of an acute first-time hamstring strain in athletes is critical for the prognosis of recovery time.
