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

Medical interventions in the management of hamstring muscle injury

European Journal of Sport Science, 2014
AbstractAcute muscle belly injuries to the semitendinosus, semimembranosus and biceps femoris (the ‘hamstring’ muscles) remain a common problem in the sporting population. Physiotherapy‐led rehabilitation remains the mainstay of treatment, and the physician's input is often minimal. Anecdotally, many different topical, oral and injectable therapies are

Influence of hamstring lengthening on muscle activation timing

Gait & Posture, 2004
The purpose of this study was to describe the changes in muscle activation patterns using surface electromyography (sEMG) during walking in patients with cerebral palsy (CP), before and after hamstring lengthening. In the current clinical use of sEMG during walking in CP for pre-operative planning, various authors have observed that timing of muscle ...

Hamstring Muscle Tightness

Physical Therapy, 1983
The purpose of this study was to examine intratester reliability of a test designed to measure tightness in the hamstring muscles. The test measures the angle of knee flexion with a pendulum goniometer after active knee extension with the hip stabilized at 90 degrees flexion. The angle of knee flexion represents hamstring tightness.
