A 48-year-old male presented to the emergency department with enlarging regions of ecchymoses over the posterior aspect of both legs (Figure 1). Four days earlier he had the sudden onset of severe achy hamstring pain during a 50-yard sprint. He denied weakness, similar prior episodes, or bleeding abnormalities. Both lower extremities had full range of motion, no loss of strength, a normal knee ...

Objective: Hamstring muscle strain is one of the most frequently occurring injuries in sports. Backward Walking (BW) and Forward Walking (FW) on the treadmill are as a common tool for fitness training in the sports. However minimal clinical research has been conducted on the effectiveness of BW in addition to conservative hamstring strain rehabilitation. Materials and Methods: Thirty, grade I a...

proprioceptive neuromuscular facilitation (pnf) training (contraction - relaxation method), in compared to the other methods of static and dynamic stretching exercises; has higher and safer effects on enhancement of hamstring muscle's flexibility, strength and endurance. achieving the optimal combination of contraction and stretching phases in pnf training that can increase these factors of phy...

Background. This study investigated the effects of short-duration high-intensity simulation of soccer fatigue on the dynamic balance and isokinetic strength of the lower limbs in youth soccer players. Methods. Thirty-nine youth soccer players completed a high-intensity fatigue simulation in 5-min. The participants performed tests on dynamic balance and isokinetic strength before the fatigue si...

Previous investigations have examined the effect of gravity correction on hamstring and quadriceps force and reciprocal muscle group ratios when tested from a seated position. The effect of gravity correction on these values when knee extension is tested from supine and knee flexion from prone has not been determined. This study tested 48 females for concentric and eccentric average force of th...

conclusions the two treatment methods had similar effects and there were no significant difference between them, while significant improvement was seen in the experimental groups compared with the control group. background shortness of skeletal muscles may cause musculoskeletal disorders of body; improvement of these muscles may improve posture and body function. objectives the aim of this stud...

conclusions simultaneous arthroscopic acl and pcl reconstructions using hamstring tendon for combined acl and pcl injuries is a clinically effective, safe, time saving and cost-effective procedure with better patient compliance and reproducible for a timely return of motion, strength, and function with favorable outcome. background multiligamentous injuries of knee are a complex problem in orth...

CASEREPORT A fit 33-year-old male with no predisposing illnesses, presented to the GP on day 4 following a muscular strain. The history given was of bending over and feeling a sudden pain in the left hamstring. The pain increased over the following 3 days. There was no obvious trauma; the patient was walking with a stick. The patient had taken 60 mg of dihydrocodeine and had felt nauseated and ...
