Device for Stretching the Hamstring Muscles

Physical Therapy, 1985
If a patient's hamstring muscles are of inadequate length, his ability to perform or the manner in which he performs various functional maneuvers may be altered. A number of methods for stretching the hamstring muscles have, therefore, been described or recommended.1–4 Of the muscle stretching techniques practiced by clinicians, the most effective are ...

TRANSPLANTATION OF THE HAMSTRING MUSCLES IN CEREBRAL PALSY

The Journal of Bone and Joint Surgery. British volume, 1967
1 . A ten-year study of fifty-four operations for transplantation of the hamstring muscles in thirty-one spastic patients has been made. 2. Twenty-one patients were improved after operation, six were not improved, and in four the duration of follow-up was too short for proper assessment. One patient died from other causes. 3.

Hamstring Muscle Injury

2014
Hamstring muscle injury is common among athletes and can range in severity from mild strains to complete ruptures of the hamstring muscle complex. Injury to the hamstring muscles is commonly sustained during eccentric contraction of the muscle while running or stretching carried out to extreme joint positions.

Architectural differences between the hamstring muscles

Journal of Electromyography and Kinesiology, 2012
The purpose of this study was to understand the detailed architectural properties of the human hamstring muscles. The long (BFlh) and short (BFsh) head of biceps femoris, semimembranosus (SM) and semitendinosus (ST) muscles were dissected and removed from their origins in eight cadaveric specimens (age 67.8±4.3 years).

Rupture of the Ischial Origin of the Hamstring Muscles

The American Journal of Sports Medicine, 1995
We treated eight patients who had complete rupture of the ischial origin of the hamstring muscles. This uncom mon injury results from a sudden forceful flexion of the hip joint when the knee is extended and the hamstring muscles powerfully contracted.

The relationship between hamstring muscle injuries and hamstring muscle length in young elite footballers

Physical Therapy in Sport, 2004
Abstract Purpose We determined the relationship between hamstring injury and hamstring length in a prospective analysis of adolescent football players as well as assessing the impact of age and test type upon hamstring length. Method One hundred and eleven footballers (9–19 years old) volunteered after subject and parental/guardian consent ...

Computed tomography of hamstring muscle strains

Medicine & Science in Sports & Exercise, 1989
Acute hamstring muscle strains occurring in ten college athletes were evaluated using computed tomography to identify the location and characteristics of these common injuries. Acute muscle strains appeared as areas of hypodensity within the muscle 1-2 d following injury.

Practical Management: Hamstring Muscle Injuries

Clinical Journal of Sport Medicine, 2003
INTRODUCTIONHamstring muscle injuries are the most common muscle injury in running and sprinting athletes, leading to significant pain, disability, and time lost from sports participation. 1–5 Persistent symptoms, slow healing, and a high rate of re-injury make hamstring injuries a frustrating ...

Mechanics of the Human Hamstring Muscles during Sprinting

Medicine & Science in Sports & Exercise, 2012
An understanding of hamstring mechanics during sprinting is important for elucidating why these muscles are so vulnerable to acute strain-type injury. The purpose of this study was twofold: first, to quantify the biomechanical load (specifically, musculotendon strain, velocity, force, power, and work) experienced by the hamstrings across a full stride ...

Relationship Between Muscle Length, Muscle Activity, and Torque of the Hamstring Muscles

Physical Therapy, 1981
The relationship between muscle length, integrated electromyographic activity, and torque of the biceps femoris muscle was investigated while the line of action of the muscle at the knee was held constant. Muscle length was changed by varying the hip joint angle. Sixteen subjects produced 1) maximal isometric contractions, 2) contractions with constant
