BACKGROUND There are still controversies about graft selection for primary anterior cruciate ligament reconstruction, especially with respect to knee stability and functional outcome. HYPOTHESIS Biodegradable interference screw fixation of hamstring tendon grafts provides clinical results similar to those achieved with identical fixation of bone-patellar tendon-bone grafts. STUDY DESIGN Coh...

OBJECTIVE To conduct a detailed analysis of hamstring injuries sustained in English professional football over two competitive seasons. METHODS Club medical staff at 91 professional football clubs annotated player injuries over two seasons. A specific injury audit questionnaire was used together with a weekly form that documented each clubs' current injury status. RESULTS Completed injury r...

Hamstring muscle injuries occur during high-speed activities, which suggests that muscular strength at high velocities may be more important than maximal strength. This study examined hamstring adaptations to training for maximal strength and for strength at high velocities. Physically active men (n = 25; age, 23.0 ± 3.2 years) were randomly divided into: (1) a resistance training (RT, n = 8) g...

Introduction: The slump test is used in athletes with suspected hamstring strains to determine the presence of neural mechanosensitivity. Other than cadaveric investigations, limited evidence exists regarding this test with respect to the neuromuscular system. Aim: To examine the effect of the slump test on local muscular and neural structures in the posterior thigh in athletes with hamstring i...

Humans and non-human primates are known to lengthen their response time (RT) to a go signal when they occasionally must cancel their responses following a stop signal in a countermanding task as well as to adjust their RT adaptively on a trial-by-trial basis. Less is clear regarding the adaptive RT adjustments in the countermanding performance of rodents. To investigate this question, male Wist...

CONTEXT There is a wide spectrum of hamstring-related injuries that can occur in the athlete. Accurate diagnosis is imperative to prevent delayed return to sport, injury recurrence, and accurate clinical decision making regarding the most efficacious treatment. EVIDENCE ACQUISITION This review highlights current evidence related to the diagnosis and treatment of hamstring-related injuries in ...

The hamstring muscle group is a vital constituent to injury prevention and lower extremity rehabilitation. During closed chain activity, hamstring muscle fibers influence dynamic interaction between the pelvis, sacrum, femur and lower leg. The hamstring muscle group functions as a frontal and transverse plane stabilizer, influencing knee flexion deceleration and eccentric extension during forwa...

Ilizarov is an accepted technique for lengthening short amputation stumps to improve prosthetic function andrehabilitation. The relation of stump lengthening and phantom limb pain (PLP) has not been reported in literature.We present here a case report of a transfemoral amputee who had a flare up of PLP following stump lengthening.He responded well to a combination of pharmacological therapy and...

  Background: Studies have shown that 75% of men and 35% of women over the age of 10 have hamstring tightness. Hamstring tightness is one of the major causes of hamstring injury and loss of function. Dry needling which is a common intervention used by physiotherapists for the treatment of common various conditions can improve hamstring flexibility in less time than other interv...

The hamstring tendons are an increasingly popular graft choice for anterior cruciate ligament reconstruction due to preservation of quadriceps function and the absence of anterior knee pain post-operatively. Two commonly used hamstring grafts are a quadruple strand semitendinosus graft (4ST) and a double strand semitendinosus-double strand gracilis graft (2ST-2G). It has been suggested that con...
